Replacing crowns in a wooden house: replacement methods, design, advice and recommendations. Old wooden floor, floor replacement: selection of materials and tools, selection of floorboards and beams, dismantling of the old floor. Replacing the floor in the house. (detailed instructions) When l

Every owner wooden house sooner or later faces the need to replace the most important structural elements of the structure. Most often we are talking about the restoration of the lower rims. This is not an easy task, requiring certain theoretical knowledge, special tools and experience in carrying out such work.

The need to replace the lower rims of the house

Wooden houses remain popular even with the advent of modern, more practical materials and construction technologies. However, wooden log houses have one significant drawback - the fragility of wood and its susceptibility to decay. The lower rims of the structure deteriorate over time.

If the construction of a wooden house is carried out "according to the mind", then the period of operation of the house without major repairs is from 50 years. But in practice this is not always the case. First of all, the lower rim of the house begins to collapse, which is in contact with water more than other structural elements.

Rapid decay of the lower rims is a consequence of the use of low-quality, unprepared material. Experienced craftsmen recommend using only larch when laying. This wood, oddly enough, becomes stronger over time when wet.

Often engaged in the construction of wooden houses non-professional builderswho are dismissive of the subtleties technological process... In addition, it is not always possible to control the quality of the material - the wood may not be sufficiently dried or harvested “out of season”. An important factor is poor waterproofing made from inexpensive brands of roofing material. As a result, after 5-6 years, the homeowner is forced to decide on the replacement of the lower crowns and reconstruction of the building.

Important! A house built of solid, high-quality dried and antiseptic wood, with reliable waterproofing and wide roof overhangs that protect the walls from snow and rain, will last at least half a century without repair.

Determine the need for repairs and the amount of work to be done will help visual inspection wreaths. When tapping with a hammer or the butt of an ax on a log, a dull sound will be heard in some places - a sign that the tree is deteriorating from the inside. A more detailed idea of \u200b\u200bthe destruction can be obtained with a little chisel work.

It is necessary to inspect and 2-3 logs located above the mortgage - the likelihood of damage is also high. It will also be useful to assess the state of the foundation. Small cracks must be sealed with paper construction tape. If after a while the strips are torn, then the base is deformed and you will have to replace the crowns and repair the foundation of the wooden house.

Ways to replace rotted crowns at home

It is highly recommended to replace the lower rims with the assistance of specialists. This process is technologically and physically very complex. Errors in work can lead to the destruction of the roof, chimney, ceiling or the entire house. In addition, self-reconstruction of a house is not safe for performers.

The repair technology depends on a number of factors: the technical condition of the foundation and crowns, the dimensions of the building, the availability of free space near the house, the proximity of the adjacent buildings, the presence of a chimney, etc. Competently choose the method of reconstruction, weighing all the pros and cons, can be a master who has experience in performing such work.

Partial replacement of crowns without raising the house

Partial repair, the so-called "point", is performed if the wood begins to rot in one or more sections of the lower belt of the crowns. In this case, it is impractical to completely change the crown.

"On-site" repair means replacing only the damaged part of the log.

pros partial replacement crown:

• ease of repair;
• the work can be done independently, without the involvement of professionals and special devices;
• insignificant financial investments.

Cons of "spot" repair:

• the formation of additional joints increases heat loss;
• structural strength is weakened.

General procedure for partial replacement of crowns:

The crown, consisting of several sections, is less durable than a solid one. Therefore, some experts recommend using this technology in extreme cases, or as a temporary solution.

Replacing the lower crown of the house with brickwork

There are two ways to replace the lower crown with brickwork: with raising a wooden house and without raising it. The choice of this or that technology depends, first of all, on the type of foundation, the age of the building and the budget allocated for repairs.

If the house has no foundation and stands directly on the ground, then it is not necessary to raise the entire building. Without lifting, it is possible to reconstruct the crowns if a columnar foundation was laid during construction.

Repair sequence:

1. The affected areas are cut out according to the technology described above.
2. A brick foundation is being laid.
3. The surface of the foundation is brought under intact logs.
4. If necessary, replace not one, but several rows of crowns.

Council. It is advisable to start the work from the corners of the house - cut off the connections at the ends and install a solid support.

A more costly and laborious way is to raise the house with jacks. With the help of a hydraulic or screw device, lifting is carried out, the elements of the log house are repaired and the masonry is started. General algorithm of actions:

1. Raise the building in the corners.
2. Place a temporary support at the corners.
3. Remove the old foundation of the house.
4. Build up brickwork, install waterproofing and lower the building.

Raising a wooden frame with jacks

When self-repairing, they often resort to technology with raising the house with a jack. The advantages of the method:

• optimal ratio of the cost of work and its quality;
• the possibility of updating the waterproofing layer of the foundation;
• high reliability.

The disadvantages of the jacking method include:

• the need for certain skills and knowledge;
• strict adherence to work technology;
• duration of the process;
• when using jacks, new joints subsequently appear.

The easiest way is to raise the house on a columnar foundation. The base of the jack is installed between the base supports, for example, concrete blocks. First, an old log is cut. If there are plans to replace several crowns, then several logs are cut out at once.

When replacing the two lower rims, two logs are cut out, the jack is installed so that it rests against the log of the third row.

When reconstructing a house on a strip foundation, the lifting procedure is somewhat different - partial destruction of the base will be required. From the corner of the house, you need to retreat a distance of about 1 m and hollow out a section 40 cm wide. The height depends on the type of jack.

When raising a building, you must adhere to some rules:

• for less skew, it is advisable to raise the house at the same time from all sides;
• on each side of the house, two or more niches must be made - it depends on the size of the structure;
• the location of niches at the same distance from the corners of the house.

Important! After the repair of crowns in a house with a strip base, the integrity of the foundation is violated, which leads to a decrease in its strength.

Phased repair of a wooden house: replacement of crowns

Preparatory activities

A log house must be carefully prepared for raising, namely:

1. Take furniture out of the house, household appliances... In general, the house must be freed as much as possible.
2. Remove the sashes and frames from the windows, remove the doors and door frames... This will facilitate the construction and protect windows / doors from damage and possible distortion.
3. Detach the wooden floor from the walls. It should be taken into account:
   • the floor embedded above the mortgage crown, which is not planned to be changed, can not be removed;
   • the logs embedded in the mortgage crown must be disassembled, the support posts installed under the logs, and then separated from the lower crown.
4. A fireplace or stove in a home is usually installed on a separate foundation. If this norm is not followed, then raising the house without damaging the heating equipment is impossible.
5. Separate the stove / fireplace chimney from the roof and ceilings.
6. The undamaged crowns of the house must be fixed and fastened. Boards 40 cm thick are nailed vertically along the perimeter of the building, the fixing step is 50 cm. Boards are nailed both from the outside and from the inside of the house. The lower end of the board is fixed to the lower remaining rim, and the upper, respectively, to the upper rim. This measure will protect the house from deformation during the lifting process.

The procedure for raising a log house: columnar and strip foundation

Step-by-step lifting of a house on a columnar foundation:

Important! You will need at least 4 jacks to raise the house. They are installed in two on opposite sides of the house - they choose the wide sides of the building. The distance to the corner of the house is about 1 m.

Raising a log house on a strip foundation:

Important! Using the lever-jack combination, the sides of the house can be lifted in turn. In addition, after replacing the crowns, it is necessary to close up the gap through which the lever was driven.

Algorithm for replacing the crown of a wooden house

The next stage is the direct replacement of the crowns. Any crown consists of a lower and an upper log connected at the corners. Jacks are installed with an emphasis on the upper logs, and the lower ones can be easily removed. In their place it is necessary to put temporary supports supporting the upper crown.

Further progress of work:

1. Carefully lower the jacks together with the upper crown. Remove the dressing log.
2. Prepare two logs for replacing the upper elements of the lower rim. The tree must be carefully processed and precisely sawed so that the fit is tight.
3. Place the top log on jacks, and cover the top with caulking material.
4. Raise the jack as far as it will go - the new log should press tightly against the counter top log.
5. Raise the jack with the house and remove the temporary supports from other walls.
6. Replace the lower harness log in the same order as the upper one.
7. Renovate the foundation, improve its waterproofing and lower the house.

The nuances of replacing the lower crown of a frame house

Mounting frame house carried out on a crown made of beams and logs. The restoration technology of the lower crown is in many ways similar to replacing the trim in a house made of timber. However, there are some important nuances:

Important points when replacing the crowns of a wooden and frame house

Many homes have wood floors. And since wood is a material that nature gave us, it is subject to decay, it can dry out and crack. As a consequence, at some point, this wood floor will require repair or replacement. And when replacing a decayed or repaired wooden floor, it is very important to follow a certain technology of complete or partial reconstruction of a wooden floor, with the help of which you can easily, efficiently and without unnecessary worries restore the old wooden floor.

Particular attention should be paid, above all, to the moisture content of the wood used. If a wooden floor is made of damp boards, then it will soon become unusable, as a result of which it will have to be rebuilt again. Since the wood is wet, it cracks when it dries and forms cracks. The moisture content of the boards cannot be determined by eye. Therefore, when buying wood, if it was in a ventilated area, the wood will be dry and its moisture content will be low. The wood for the floors is dried separately from the joinery. It is worth paying attention to the ends of the boards: it is strongly not recommended to coat them, as this will ultimately lead to their decay.

After selection the right wood you can go directly to the repair of the floor. When replacing wooden floors or decayed boards, use new ones of the correct size. Having carefully examined the remaining whole boards, you need to pay attention to the location of the old fibers. This is to ensure that the fibers of the fresh boards run parallel to the old fibers. If it is necessary to replace them, then the old boards are treated with an antiseptic. Remaining old boards suitable for replacement must be laid in the same order in which they were laid on wooden floor, according to their numbering. New boards are treated appropriately on the edges and on the back.

The width of the board should be 76-124 mm, and its moisture content - 12%.

• The wooden floor is laid perpendicular to the joists.
• If nails are used when replacing the floor, they should be twice as long as the floorboards are thick.
• You need to nail the boards at an angle of 45 degrees.
• The heads of the nails should go no more than 5 mm into the surface of the board.
• The rows of hammered nails should be neat and even.
• It is best, of course, to use self-tapping screws when repairing the floor.

Under constant load, nails begin to bulge out of the floorboards and, accordingly, no longer provide their reliable fastening. To prevent this from happening, it is necessary to use self-tapping screws, which can also be screwed in next to the old nail, and the resulting small depression is sealed with a special putty for wood. The boards are laid on a common log along the entire length or width of the room, articulated and covered with a frieze. The frieze is fixed with nails to the log in a couple of rows.

A small distance should be left between the flooring and the wall to ensure good sound insulation. The gaps are covered with a plinth. The floor covering in the room should be 1.5-2 cm lower than the floor in the hallway.

The procedure for repairing a log is the same as for a wooden one flooring, that is, they are replaced by new ones.

• They are treated with an antiseptic, rotten logs are removed.
• Logs on a reinforced concrete base are installed on soundproofing pads.
• If the logs are laid on the ground, it is necessary to lay out small columns from brick or concrete, and lay the waterproofing in two layers of roofing tar.
• To align the lags in relation to each other, use a building level.
• The first logs should be laid at a level across the room, leaving a gap between the wall of 8-9 cm.
• Do not put wedges under the logs.
• When the first lighthouse logs are precisely verified, others are laid over the entire area.

It is recommended to lay logs, focusing on the degree of illumination. In light rooms, the logs are laid along the incident rays of light, and in dark places, for example, in the corridor, across. The joining of the lags is carried out end-to-end, while the offset of the parallel lags is at least one meter.

After the logs are laid, and the level is verified, it is advisable to start laying the boards with or without clamps. It is necessary to lay the boards closely so that the width of the gaps is no more than 1 mm. When fitting the ends and joining the boards on the log, the nails are nailed into them at an angle, sinking to a shallow depth. Hanging floor boards is unacceptable, as you will have to lay an additional log under them. To get rid of unevenness between the boards, it is necessary to use a sander to level the top layer of the floor covering. A planing machine is used to cut the floor, pre-wetting the floor surface with water. When turning the machine in the opposite direction, overlap a nearby cut strip by 50-100 mm.

After completing all the repair work, the wooden floors are cleaned of shavings and sawdust, the surface is primed and putty. When the putty dries, the floor surface is cleared of debris, the dust is removed with a damp cloth, and only then the floor is painted or varnished.

Good luck replacing or renovating your old wood floor.

Wooden houses are comfort and coziness, a special microclimate and positive energy. In order for it to serve for a long time, you need to carry out current repairs on time and with high quality.

The experience of operating wooden buildings shows that without special tools, experience and knowledge, structural elements it is extremely risky to touch structures. When replacing crowns and repairing the foundation of a wooden house, the cost of professional services will pay off with the durability of the structure.

Causes of destruction of the integrity of the lower rims

Ideally wooden building will stand without overhaul half a century. The “weak link” of the design is the bottom rows. Moisture seeps through the cracks inside the wood and through the cracks between the logs. In damp places, fungal spores begin to develop. Mold appears, then rot. Internal destruction of wood is completed by insect pests.

The reasons why wood is destroyed can be the following:

Use of unprepared material. Raw wood harvested “out of season” quickly loses strength and begins to deteriorate.

The wood species is of great importance. For example, when choosing larch for the construction of the lower rows, you don't have to worry about high humidity, the tree will only become stronger. It is not recommended to use linden logs as lower rims.

Poor-quality waterproofing of the foundation, performed in violation of technology.

Failure to comply with the antiseptic technology of building material.

Insufficient air exchange in the underground space, lack of ventilation ducts.

Incorrectly erected foundation that does not correspond to the type of soil, relief, without taking into account the depth of the groundwater, climatic conditions region.

Illiterately assembled front panels covering the crowns.

All reasons boil down to two main factors: improper use of the home or an unprofessional approach to the work of builders.

How to determine the degree of destruction of the crowns

To radically resolve the issue of replacing the crowns in a wooden house and the degree of reconstruction, it is necessary to determine the extent of the damage.

The dull sound of an ax butt on a log will give out the degree of destruction of the wood from the inside. If you work with a chisel, you can imagine a more complete picture of damage. Routine inspection is not enough to correctly assess the condition of the building. A professional approach involves assessing the state of the foundation, determining the degree of load on the structure. An accurate forecast of the further operation of the dwelling can be given by experienced craftsmen... If you do not need to completely change the rows of logs, you can save the family budget. And, conversely, time, effort and money can be spent on local repairs, but it will not lead to the expected result.

On our website you can find contacts of construction companies that offer a foundation repair service. You can communicate directly with representatives by visiting the exhibition of houses "Low-rise Country".

Features of reconstruction

Before starting work, you should free the premises from furniture and things. Take out window framesremove the doors and take apart the door frames.

The chimneys of the stove or fireplace are separated from the ceilings and the roof. They do their best to facilitate construction and avoid distortions. Hold the intact rows together.

Illiterate actions can damage the roof, chimneys and attic floors... Therefore, it is not recommended to carry out them yourself.

The technology is quite complex and depends on the following points:

foundation conditions;

the degree of destruction of wood;

dimensions of the building, number of storeys;

sizes free space near the building;

the presence of adjacent buildings,

chimney design and condition.

If the furnace does not have a separate foundation, as provided for by the construction technology, it will not work to raise the house. A specialist who has the necessary knowledge and experience in this area will be able to choose the right method of restoration work.

Whenever possible, materials are used that are as close as possible to the original ones; sometimes it is advisable to replace the decayed parts with bricks.

Sometimes wooden facades covered with siding or bricked to hide the elements of reconstruction. A waterproofing layer is laid between the foundation and the new rows, the wood is treated with an antiseptic.

Reconstruction methods

There are several ways to repair crowns:

Partial replacement (local restoration of wood rotting places).

Brickwork instead of damaged crowns.

Replacing a lower log in a wooden house when lifting a log house with jacks.

Each of these methods has features, advantages and disadvantages.

Partial crown replacement

Assumes local reconstruction. This is the most affordable and low-budget way. Spot repair is possible when the wood has just started to deteriorate and does not have a large scale of damage. However, this technique has a drawback - the strength of the structure decreases, the heat loss of the room increases. With a competent approach to business, you can minimize these shortcomings.

An important point: it is necessary to correctly determine the boundaries of damage. If this is not done, the effort will be in vain. The decay process will continue.

In order for the inserts to hold for a long time, their dimensions must fully correspond to the removed elements. Around the places where new bars are inserted, craftsmen make special holes for driving in dowels.

Brickwork instead of damaged crowns

Partial wood restoration technology is a temporary measure. Therefore, brickwork is more often chosen as a way to solve the problem. This can be done with or without jacking up the entire structure. The age of the building, the type and condition of the foundation, possible material investments are taken into account.

Places affected by rot are cut out. The end connections are cut off and solid brick supports are installed in their place. A brick foundation is laid, its surface is brought under undamaged logs. With this method, several rows can be updated at once.

If the brickwork is carried out with the lifting of the structure with jacks, the scheme is as follows:

When replacing the two lower rims, cut out two logs and set the jack in such a way that it rests against the third row.

The structure is raised at the corners and temporary supports are installed. To avoid dangerous distortions, the structure is raised simultaneously from all sides.

The old foundation is being removed.

The structure is lowered only after it has been completed brickwork and a waterproofing layer was installed.

Complete replacement of the lower rims

Unlike local repairs, the cost of replacing crowns in a wooden house using hydraulic or screw devices will cost more, but the result will justify the money spent.

The jacks are installed with an emphasis on the upper logs so that the lower ones can be removed. Temporary supports are being erected. The equipment used to lift the structure must be reliable. Breakage of the jack while lifting the structure can lead to a violation of the integrity of the structure and personal injury.

Although the jacking process will require more time and effort, the lifespan of the structure before the next major overhaul will increase significantly. The renewed waterproofing layer will keep moisture out of the wood walls.

What is the price of

When replacing the lower rims of a wooden house, the cost of work depends on the complexity of the repair, the degree of wear of materials, the terrain, and the size of the house.

When the lower rims of a wooden house are replaced, the cost of the work consists of the following components:

The whole range of actions to raise the structure.

Dismantling the damaged crown.

Preparation and installation of a new crown.

Construction of a new foundation.

Waterproofing device.

Installation of fasteners.

To this should be added the cost of building materials.

On average, the cost of services for replacing the lower crown in Moscow starts from 5000 per 1 sq. M. rubles at the most small size timber. If the walls are made of logs, then the price for replacing crowns in a wooden house will be more expensive: from 13,000 rubles per 1 sq. M.

Conclusion

Determining the exact scope of work and the right way restoration of the lower rims will allow you not to spend extra money on reconstruction. Handicraft restoration can lead to distortion of the structure and further destruction of the house.

It makes no sense to save on hiring specialists, because the price of work to replace a crown in a wooden house is not sky-high and it is better to carry out a reconstruction once with a high quality than constantly face new problems.

Ecology of consumption. Manor: Repair of the most vulnerable part of a wooden house - the lower crowns - is a very laborious work. Usually it requires the involvement of specialized teams with the appropriate equipment, but in some cases it can be done by hand.

Repairing the most vulnerable part of a wooden house - the lower rims - is a very time-consuming job. Usually it requires the involvement of specialized teams with the appropriate equipment, but in some cases it can be done by hand. It all depends on the type of foundation and the extent of damage to the wood of the lower rims of the house.

Types of repair of the lower rims of the house

Consider the types of repairs, as well as the production technology in each of the possible options.

Repair without raising the house:

• with the replacement of the lower crown section;
• complete replacement of the lower rims with fragments of logs;
• replacing the lower crown with brickwork.

Repair with raising the house:

• replacement of the crowns of a house with a pile (columnar) foundation;
• replacement of the crowns of a house with a strip foundation.

The indicated types of repair of the lower rims are arranged in the order of increasing production complexity. Replacement without raising the house can be done independently, without the involvement of outside help. Lifting a house requires synchronizing the efforts of at least two people working with the jacks to avoid skewing and destroying the house or sliding it off the foundation.

Preparing the house to replace the crowns

The first stage of replacement is to strengthen the structure of the log house. Even if it is not planned to raise the house with jacks, it will be useful to strengthen the structure. For strengthening use wooden bar at least 40 mm thick, located vertically along the outer and inner surface of the wall.

The lower edge of the timber should be at the level of the crown, which cannot be replaced, the upper edge - at the level of the upper crown of the frame. The screed bars are attached to the wall with nails. At the upper and lower points, they are fixed with a tie (pins of at least 10 mm) through a through hole drilled in the wall (log). The screeds are located at a distance of 300–400 mm from the edge of the crown section to be replaced, or in all inter-window spaces of the wall.

Diagram for replacing a section of a log

First, the affected area of \u200b\u200bthe wood is determined. It is visually difficult to understand how widespread rot has spread. To accurately determine the damage, either a chisel is used, with which the log is channeled from the side of the visible area of \u200b\u200bthe lesion, or a feather drill in wood, with which holes are drilled using an electric drill.

The condition of the wood is determined by the condition and color of the shavings. Having decided on the section to be replaced, they retreat 200 mm to the sides from its borders, and with the help of a chain petrol or electric saw, a section of the lower crown is cut out. After that, two layers of waterproofing are laid on the foundation.

Replacement of part of the crown. 1. Damaged area. 2. The cut area with a margin of at least 10 cm from the detected damage. 3. Insert

On unaffected areas of the lower rim, cuttings are cut out with a saw for more reliable fixation of the insert element. The lower part of the second crown is treated with an antiseptic. An insert is cut out of a log of the corresponding diameter; its length should be 10–20 mm shorter than the cut area.

The length of the cut must correspond to that of the undamaged parts of the lower rim. After that, the insert is installed (hammered with a sledgehammer) into the opening and the existing cracks are poured with moss or other available material.

Thus, you can gradually replace the entire perimeter of the decayed crown. The replacement starts from the corners from the lower log of the log dressing.

Alternatively, it is possible to replace the damaged area not with wooden inserts, but with brickwork.

Replacement of a log house on a columnar (pile) foundation

This is an easier option, since it does not require the destruction of the foundation. The distance between the piles or foundation posts is usually sufficient to accommodate the jacks. To prevent the deformation of the log house and its sliding off the posts, it is advisable to raise the house synchronously from all four corners of a simple rectangular log house. Only in extreme cases is it possible to lift only one side of the house.

The jacks are put under the upper log of the log dressing. A support is placed under the jack to prevent falling into the ground ( wooden shield not less than 500x500 mm). The jack rod should not rest directly on the log, but have a metal plate-plate. After lifting with jacks, the lower dressing log is released from the load and can be replaced. Temporary supports made of logs or bricks are installed on it and jacks are lowered.

Simultaneously with the jacks, the upper logs of the frame dressing will also be lowered. They are also replaced and immediately jacked up. After that, the temporary supports are removed from the lower logs of the dressing and the jacks are lowered. The blockhouse falls into place.

Replacing the crowns of a log house on a strip foundation

This work is the most difficult because it requires either partial destruction of the foundation to form niches for the installation of jacks, or the use of a lever system for raising the corners of the house.

The replacement of the crowns, as in the case of the columnar foundation, begins with the replacement of the lower logs of the ligation of the log house. For this, niches are grooved in the foundation at a distance of 200–300 mm from the corners of the house under the upper dressing logs. After installing the jacks, the replacement procedure is similar to that described above.

When using a lever system, destruction of the foundation is not required. The initial stage is the sampling of half the thickness of the upper log of the frame dressing at 1000–1500 mm from its edge from all four corners of the frame.

After that, a metal channel or rail is laid in the formed niche, and the corner of the house is raised with a jack. As it rises, wooden wedges are hammered between the foundation and the channel (rail) until the lower bandage log is released from the load. It is removed and temporary supports are substituted.

Next, wedges are knocked out between the channel and the foundation and removed. The upper dressing log is released and can be replaced with a new one. After that, the channel or rail is installed again and the house is raised using wedges in the same way. Temporary supports are removed and new lower logs are laid for the bandaging of the log house. Lowering the jacks and knocking out the wedges, the log house is lowered onto the lower dressing log. The blockhouse fell into place.

Despite the technology of replacing the lower rims of wooden log cabins, which has been developed over the centuries, this work still remains very time consuming and requires great physical strength. It is impossible to do it alone. But the point is not only in physical activity, but also in the need to synchronize the rise of the log house at the same time in 2 or 4 points. And with a complex structure of a log house - in an even greater number of points. Nevertheless, replacing only the lower rims is a much less time-consuming process than a complete bulkhead of the entire log house. published

Replacing wooden floors with reinforced concrete

Any structure consists of several basic elements: foundation, floor, roof and walls. Distinctive feature wooden floors is the emerging need to replace them. This is due to the minimum service life. If the service life of foundations, walls and reinforced concrete covers is practically the same, then wooden structures are used for about 50 years.

Replacement relevance

Most of the buildings and structures that need renovation worksah and were built a long time ago, they have wooden interfloor ceilings. After a certain period of time, such structures lose their quality and functional properties, therefore, the need for change is formed.

The solution to the topical issue of the buildings of the old fund is to reject wood. Structures with wooden floors in most cases have a small number of floors and thick and strong load-bearing walls. Some buildings are of historical value and serve as museums.

After analyzing the house, experts decide what kind of floor to replace the wooden one: with a protective structure made of reinforced concrete slabs or reinforced concrete, which is a monolith.

A brief excursion into history

Structures are divided into monolithic and prefabricated. Monolithic structures were limitedly used until the mid-90s of the last century. This was due to the lack of:

• special mechanisms and equipment that allow the delivery of concrete mix through the structure under construction;
• reversible formwork.
• Since the 50s of the XX century, construction technologies have involved the use of prefabricated reinforced concrete structures.

Work principles

Replacing wooden floors with a practical reinforced concrete structure is based on the use of beams. They are laid at their ends in load-bearing enclosing structures. And also in existing recesses, in which there were old beams or in additional open holes.

In almost all structures in which there is a need to replace floors, load-bearing walls represent longitudinal vertical enclosing structures located in parallel. Therefore, when creating a project or renovation plan, it is necessary to take into account the distribution of the load on these walls.

The use of a structure in the form of a monolith for these works is not advisable. Since in order to obtain the necessary support on the walls, the need is formed to create holes along their entire total length, which leads to a weakening of the wall structure.

A prefabricated slab is a complex of cross beams, blocks located between these elements, and a reinforced monolith. An important element of formwork has a rectangular base made of light reinforced concrete, an upper base made of reinforcement.

For a single floor, they are used, taking into account the load indicators on the load-bearing walls, wide-profile standard profiles - I-beams or metal profileslightweight.

Characteristics of the building materials used:

• profiles of steel products;
• brand and type of concrete;
• thickness of reinforced concrete coating;
• other parameters.

They are determined when creating a project before starting the main construction and repair work, taking into account the state of the structure, the features of operation and the main reassignment of the structure.
