When not one floor is planned in a residential building, but two or three, it is imperative to think over the design that will lead to the upper tiers. A drawing of a metal staircase, created on the basis of measurements, will help facilitate the work and make the arrangement process accessible.

Schemes and drawings of metal stairs

The design of the metal staircase has all the necessary safety and durability parameters. That is why they often rely on this type of product. The metal is practically not subject to corrosion, advantageously emphasizes the style of the room and brings rigor and elegance to the design. Looking at the wide variety of metal stairs offered, one can understand that even a person who does not have experience in such incarnations can make them with his own hands.

Dimensional drawing of a metal staircase

The most important thing is to choose a design that will be feasible to draw, prepare and install in the space of the room or outside it.

Advantages

Flaws

1. One of the disadvantages can be called the bulkiness of gangways and railings. But thanks to the skills of modern developers, you can easily choose a scheme that will best match the load for a particular room.
2. Some curves and decorative elements are difficult to bring to life without special skills.

Based on the priorities and disadvantages of the material and design in general, one can bet in favor or against such a decision.

Metal staircase on stringers

It is much easier to make a drawing of a metal staircase if the structure is equipped with stringers. This is due to the fact that you need to calculate the distance for each step and prepare the material, which will subsequently be fixed to the base. Stringers are the base (base) in the form of a future staircase.

It can be made from different materials and be fixed as required by the premises. Of course, measurements are still required to purchase suitable stringers.

After all, the design must fit the parameters of the space allocated for the stairs. A ladder on metal stringers will help even inexperienced craftsmen to complete the installation task.

The main thing - correctly with a mark of the place where the gangway will be located. And also have at hand the tools and materials necessary to implement this idea in your own home.

Advantages

Design option for a metal staircase

Due to the fact that gangways equipped with stringers have earned their calling, the positive aspects of such a solution are obvious:

• This makes the work process easier;
• Allows you to easily organize the order of actions;
• Such structures are strong and durable;
• Thanks to the stringers, even an inexperienced specialist or just the owner of the house will be able to realize his plans and make it a reality;
• This element allows you to devote more time to details and design experiments that will decorate.

These are far from all the positive aspects of the stairs on the stringers; each owner of a private house finds his own independent advantages.

Flaws

It is necessary to correctly determine the size of the base for the steps so that the design fits clearly into the interior. It is easy to make such calculations. Simply measure the height, angle and width of the desired installation.

How to draw a metal staircase drawing

Make your own drawing of a metal staircase with my own hands simple enough. To do this, you need to measure the space in which the steps leading to the second floor will be located.

Required materials for measurement

In order to carry out the measurement of space, the following accessories should be at hand:

• Roulette with maximum length;
• Surface level gauge;
• Chalk or a special felt-tip pen with which you can make the necessary marks on the wall, floor and ceiling.

This is the minimum set of accessories that will help you quickly and efficiently carry out the measurement process.

Required materials for the drawing

To make the scheme as accurate and correct as possible, you should also prepare a number of stationery items. Namely:

• Sharpened pencil or black marker with a thin rod;
• A sheet of paper or whatman paper;
• Ruler;
• Compass.

The diagram should be drawn carefully and accurately so that during the direct installation process, errors that are difficult to correct are not made.

What parameters need to be measured

In order not to miscalculate and correctly make a drawing with your own hands, you will need to make the following measurements:

After taking measurements, you can transfer the recorded parameters to a sheet of paper, forming a diagram of future gangways.

What nuances must be taken into account in the process

When carrying out measurements, be sure to pay special attention to the following factors:

What are metal stairs

It happens differently, but each of them is worthy and we often choose. The designs of metal stairs are:

screw	Such gangways will help to save a maximum of usable space in the room. The steps will favorably emphasize the sophistication of the design and add a spark to the overall picture of the interior space. The only thing that can stop is the complexity of the independent implementation of the drawing. Without special skills, a person cannot cope with the measurements necessary for such a complex structure. As well as the direct process of installing ladder structures requires some skill and skill. Knowing all the features spiral staircase, a person will be able to realize the idea with the installation of such a design of a gangway. After the implementation of the plan, the interior will immediately sparkle with new colors.
marching	This option is most often used to implement the idea of ​​​​installing ladder structures. For such an array, it is easy to draw a diagram even for those who have never encountered such a task before. Marching stairs are straight, leading to the second floor or with turns (this helps to save space). It is very simple to measure the parameters required for the drawing of any of these types of gangways. Enough to have on hand necessary tools and fixtures. Direct installation of the structure is also elementary. You just need to follow the step-by-step actions that you can read about in any thematic literature.
hinged	There are structures leading to the second floor, holding on to the wall. Supports are not installed under such structures. The main load-bearing and load-bearing structure is the wall. Therefore, before proceeding with the action, you should make sure that the walls are strong and ready to withstand such a high load. If so, then you can safely equip a hinged metal staircase. Such a staircase will help save space, make the style of the room exquisite.

Specialized design programs significantly save time when developing drawings, calculating the main dimensions of structures, and compiling accompanying documentation for products. In addition, using the programs, there is no doubt that all design stages will be carried out in compliance with the existing SNiP and GOSTs. The article will help you understand how to build a staircase in AutoCAD.

Modeling

The program allows you to design structures for any purpose, even for a beginner who does not have special experience in owning a system that includes:

• Metal buildings for industrial and domestic purposes;
• Firefighters;
• Instructions for assembly and installation of any other design options.

The program has its own data library, which includes regulatory documents for choosing a design, its parameters or SNiPs, and rules for building a model. A series of regulations includes the basics of building metal structures, GOSTs for the materials used, requirements fire safety and elementary rules of town planning.

The documentation or series regulates the basics of building a structure, fencing for them, provides rules for the competent installation of products and operation, there is a list of additional elements.

Structure design procedure

Drawings executed in the AutoCad program must comply with certain rules:

• First of all, center lines are drawn, passing through the center;
• The location of the march is tied to the walls of the building;
• On the main view, the floor levels of the first and second floors are marked;
• On the cuts, all bends and bevels should be visible;
• On the wiring diagram, behind the contour of the main projection of the product, the dimensions of the room are applied in thin lines, the placement of openings for windows and doors in it.

To develop a drawing "for yourself" - these are the basic provisions for working with the program.

Type selection

Initially, you should choose the type of its design and material of manufacture.

Types in AutoCad

Types shown in the photo:

• a - straight single-march;
• b - straight two-march with an intermediate platform between marches;
• c - L-shaped two-march with a corner platform between the marches;
• g - U-shaped two-march with an intermediate platform in the corner of the room;
• e - three-march with platforms in between marches;
• e - single-march curvilinear, located near the wall;
• g - single-march curvilinear, placed in a rectangular volume;
• h - screw;
• and - single-march with a turn of 90 ° and winder steps;
• k - single-march with a turn of 90 °, with lower and upper winder steps;
• l - single-march with a turn of 180 °, with winder steps in the middle of the structure.

The choice of type is influenced by:

• The area allocated for its installation;
• Ceiling height;
• Architectural style.

The choice of material depends on the solidity of the house and the degree of its fire resistance. The most convenient design, which provides the safest ascent, is a flat one-flight with 15 steps.

Composition of a march in AutoCad

How to draw in autocad

When creating a virtual structure, ready-made blocks are used, which are offered by the program - they can be edited by setting the required parameters. The composition includes several basic elements.

These include:

• Prefabricated steps;
• Area;
• Fencing;
• Railing.

Blocks for autocad

In the AutoCad program, drawings are created by compiling and selecting parameters for each specific element. The versatility of such computer software allows you to perform and calculate in advance absolutely any design with or without a platform.

Elements of marches with platforms

The entire drawing is developed in section, which allows you to carefully view all the selected elements. Each of them in the drawing has the appearance of not only the structure itself, but also all the main dimensions.

A set of ready-made documentation, which was developed in the AutoCad program, includes a longitudinal and cross section of objects, a specification with the necessary fasteners. Everything is done in compliance with the relevant GOSTs.

Steps and marches

Marches and nodes in AutoCad are performed in accordance with GOST 9818-85.

Steps for them can be:

• Flat without friezes - LM;
• Ribbed with friezes - LMF;
• Ribbed, which include two half-platforms - LMP.

At the same time, flat ones are installed on a slab, and ribbed types - on a stringer. At the same time, LMP marches have a large-sized structure, united together by a slab.

For each type of structures, a site is selected, which is laid down in the program.

Tip: You should pay attention to the turn - it can be right and left.

After the development of working drawings, an assembly diagram for the placement of structural elements on the construction site is drawn up. To do this, each node in AutoCAD is marked with a specific brand, which are placed on the assembly drawing.

Wiring diagram

Design with given parameters

For example, consider the most difficult option- creation of a structure in the AutoCad program. In this case, the steps from bottom to top are placed around a common rack.

The user sets the radius on the screen, in the absence of restrictions on the trajectory of the model. Otherwise, the radius must be determined taking into account the given tread length and its shape parameters. To get the desired radius, you should adjust the length of the tread.

Initial design stage

To create a model of a given tread width along the midline (T), you must:

• Form a structure twice the width of the given distance (A);
• Using the "Edge adaptation" function, the outer edge is moved to a position that corresponds to the overall width B;
• The offset value is B - 2A.

Design

Tip: Before selecting tools, to display the properties palette, you need to click in sequence: the Home tab, then the Create panel, then the Tools drop-down list and Properties.

After that:

• Open the palette of tools required for work, and select the desired tool;
• On the properties palette, go to the "Design" tab and expand the "General" and "Basic" nodes;

• The location is set;
• Development continues;
• Enter is pressed.

In more detail, the construction of any design shows the video.

Modern technologies can significantly save time on the development of drawings, wiring diagrams for metal structures, on the necessary calculations. The program allows you to get acquainted in 3D projection with all the corners of the staircase structure, to see its location in the space of the room. By designing a section according to the model, one can get an idea about its design, about internal arrangement the entire building.

The use of specialized computer program allows you to significantly simplify and speed up the construction in AutoCAD. However, if possible, it is better to entrust the process of developing drawings to a professional. The price of even a small mistake is too high, because the staircase is one of the most important components of the building.

Stairs - bearing structures buildings serving for vertical communication between floors. When designing a staircase made of prefabricated reinforced concrete steps along steel stringers, it is important to pay special attention to the interconnection of the individual parts of the staircase.

If the supporting structures of the flight of stairs and the interfloor platform are channels, then they can be connected using a mounting element from a hot-rolled corner, to which the supporting structures are attached by welding.

With the help of standard parts from the SPDS GraphhiCS database, you can quickly draw the junction of the stairs to the interfloor platform (If you have not installed this program yet, you can do this using). The drawing created in this way in AutoCAD will be dynamic, that is, it will be easy to make changes.
