Calculation of the grid reinforcement calculator. Calculation of the reinforcement grid. How is the calculation of the fittings of the foundation

In order to significantly increase the strength of monolithic concrete structures, a special reinforcement grid is used. To properly perform all the necessary installation operations, you will need to know how to calculate the reinforcement grid. If you do not know the weight of the material, its length and the value of the magnitude of the loads, which can withstand the design, will never be able to perform the correct reinforcement.

Improper strengthening of reinforced concrete structures may result in serious consequences. Cracks will appear, the service life will significantly decrease, sometimes it can lead to the destruction of the building or structure.

In this article, we will analyze all questions regarding the calculations and selection of the necessary material during the construction of various objects.

To begin with, it is necessary to understand why in general they perform the procedure for reinforcing reinforced concrete structures of various purposes. First of all, it is necessary in order to make the construction object more durable and monolithic. The grid will pull the concrete, thereby increasing the rigidity. This will allow you to withstand heavy loads, as well as the service life will increase.

The reinforcement procedure is quite complicated and requires high accuracy. Therefore, before starting strengthening concrete structures, you will need to perform all the necessary calculations of the main indicators and characteristics. This will help not only choose the need to choose the necessary material, but also to save significantly. You will know exactly what the number of relevant products should be purchased.

Different building structures (gender, inter-storey floors, walls, supports, plates, etc.) require strengthening. Depending on this, a specific reinforcement scheme is selected. This scheme includes a number of rules and basic provisions, in accordance with which the installation and assembly of the metal grid will be carried out. Accordingly, the calculations of the main parameters will be performed in different ways.

How to calculate the mesh reinforcement - the main parameters for the calculation

It will be necessary to define the following parameters:

Accurate amount of reinforcing grid;
Full mass (weight) of the necessary products;
The principle of laying the mesh;
Carrying capacity and maximum allowable external loads.

If it is required to strengthen the foundation of the building, then in this case there should be both a longitudinal and transverse firming layer, which are stacked at a certain distance from each other. The grid has standard dimensions that do not always have enough to cover the entire base area. Therefore, it is necessary to connect several products, as a result of which the place of the joints appear. For high-quality junction joints, steel wire is used.

If the reinforcement of the interheautable overlap is performed, then two layers will be put here, and connect them into a strictly parallel position using high-quality wire. In the case of the walls of the building or the foundation of a ribbon type, the firming frame may consist of three layers. When reinforcing columns and supports of various types, the frame is laid and connected in a round or rectangular position.

6 parameters that should be considered when selecting the grid

The definition of the main characteristics will help not only to count its costs, but also to understand what products in each case will suit the best. The metal grid is selected depending on the root of the reinforcement and features of the construction object.

There are six basic parameters that should be considered when selecting the grid:

The diameter of steel rods from which the product is manufactured;
Appropriate product class;
Values \u200b\u200bof maximum loads;
Values \u200b\u200bof the mass and length of the product;
Specific place of installation and form of reinforced concrete design;
Product price.

The diameter of the rods will be one of the most important indicators to pay attention to first. The number of perceived loads will depend on this indicator, and, consequently, the strength of the structure will depend. The thicker the mesh rods will be, the more loads it can withstand. The diameter will affect other indicators. For example, the more it will, the greater the mass and price.

To strengthen highly loaded plates and bases, products with rod thickness from 13 to 30 millimeters are used. Elements of buildings or structures that are not exposed to a large effect of external forces can be rejected by a grid with a rod diameter from 8 to 12 millimeters. In some cases, combined options are used when the grid with different thicknesses is used in one reinforced concrete structure.

How to calculate the grid reinforcement

The calculation of the reinforcement grid is divided into two main stages. At the first stage, the calculation of the loads that will affect, and at the second stage determine how much products are necessary.

Determination of loads will help to understand how much weight will be able to withstand the finished design, as well as what forces and in what places will influence. On the basis of the data obtained, the grid of the appropriate size is selected. Only after that you can proceed to the definition of the required amount of metal products.

The first stage of calculations is quite complicated and requires professional skills and knowledge. Special formulas apply here, taking into account the set of additional coefficients. If you do not have sufficient knowledge, then this work is best trusted by trained professionals. When erecting large buildings or structures of various purposes, all necessary calculations are performed at the design stage.

Calculation of the required amount of material

After all the necessary indicators of the future reinforcing framework were defined in the first stage, you can begin to determine the required amount of material. There is nothing complicated here, everything you need is the usual calculator and sheet of paper. Knowing the geometric sizes of the frame and the standard dimensions of the grid sheets that are sold, you can calculate the desired amount of material.

With the result obtained, you can already go to the seller and order the amount that is necessary for the manufacture of reinforced concrete design. In this case, you will never have excessive fittings, plus you will save a little on it.

1 meter Armatures \u003d. 1 m x (0.785 x d x d)
In brackets area surroundings. D - diameter.
Specific weight \u003d 7850 kg / m³

If you want to get the weight, then you need to multiply the volume on the proportion.

Example

We consider volume: 1 m x (0.785 x 0,012 m x 0,012 m) \u003d 0.00011304 m³

We consider the weight: 0.00011304 m3 x 7850 kg / m³ \u003d 0.887 kg

How and for what weight calculation is performed

Determination of the weight of the mesh for reinforcement is performed to understand how much the ready-made construction object will weigh. This parameter will also be very important when choosing ways to deliver products to the construction site.

First, it is necessary to know the diameter of the rods from which the mesh and the geometric sizes of the cells are made. There are special tables in which the weight of the product is specified depending on the above parameters.

If an individual order was performed on the manufacture of a non-standard grid, it is not possible to calculate the weight of this product on the table, because it takes into account the standard dimensions. In this case, it will be necessary to use special formulas for calculation. If you do not want to do it yourself, you can delegate the task of experienced professionals, which in a short time will calculate everything.

What is a selection calculator

On the Internet, you can meet various online calculators that help determine all the necessary parameters in several clicks. These are specially programmed algorithms. To calculate, you will need to specify the basic parameters, and the program will give you the result.

There are two types of calculators. The first type helps determine the load, and the second is to calculate the weight and cost of metal. Load calculator gives only a general presentation, but not exact data. Therefore, it is impossible to use it to draw up a project. Accurate load values \u200b\u200bshould be calculated only by experienced people and with the help of special formulas and algorithms.

Weight Calculator and Prices You can fully utilize. It gives out fairly accurate indicators. The program has several fields for filling. These indicate the thickness of the rods, the sizes of the cells and the cost of one ton of specific products. If the reinforce the designs have a rather complicated form, then the grid will have to cut. In this case, it is necessary to consider an additional percentage. In most cases, this is not more than 5 percent.

After you filled all the fields, press the calculation button, and the calculator will give you the testimony of the weight of the material and the total cost. Finding such programs on the Internet is very easy, just to enter the corresponding request to the search string.

For high-quality strengthening of various reinforced concrete structures (floor, overlapping, plates, blocks, supports, bridges, etc.) you need to know how to calculate the mesh reinforcement. This procedure consists of several steps that must be successively executed. Each of these stages, we dismantled in detail in the article.

Steel reinforcement grid is most often used to strengthen various designs. It is made from a metallic thread of different diameters, may have additional corrosion protection. A small proportion of the reinforcement grid simplifies its installation and transportation.

The quality of this product

Characteristics of welded grids depend on their purpose:

masonry and road;
strengthening thermal insulation and glass.

Use wire with a low carbon. The rods of different lengths are welded with contact point welding. Corrosion protection is carried out by plated by a polymer or galvanizing, which is carried out in several ways:

bruh galvanized before welding;
electrolytic method;
hot coating.

Armature without a galvanized layer is called light.

On the welded grid for glass, the heat insulation is applied with a range of 1 or 2 layers.

The mass is calculated depending on the size of the cell, the distance between the wire axes, the range of galvanis:

Mesh grid area translation tables

The reinforcement metal products is used for such purposes:

reinforcement of reinforced concrete products;
strengthening coast;
reinforcement of the road fabric;
in the household (manufacture of fences for the bird);
fencing territories.

The mass of 1 square meter of metal wear depends on the length, the width of the cells, the area of \u200b\u200bthe cross section of the rod, the specific weight of the material. The size value Ø rod ranges from 0.5 to 8 mm.

The form of the production of products from the welded reinforcement:

rolls;
cards;
panels.

The dimensions of the reinforcement grid depend on the form of release. Products in maps reach a length of 6 m. Maximum width - 2 m, minimum - 35 cm. The two-meter panels have a width of 2.5 m. Rolls are released with a width of 0.2-2 m, 15-118 m long wide.

The dimensions of the window depend on the purpose, there are 6 * 6-20 * 20 cm. There are rectangular, with different overall values.

Standard TU 14-4-1284-88

Products on these specifications are made with square and rectangular windows.

From light, with a large cell size, cages build cells for the content of birds and fur animals. It is used to strengthen reinforced concrete structures, making them stronger. But for this, the metallet must be high quality. You should not use the product that the welding points are located not at every point of touching the rods, but through one. Such technology significantly reduces quality. This may affect security.

For construction work, rods with a diameter of 0.6, 0.8 and 1 cm are used. The higher the load on the structure, the stronger the grid must be, the greater the wire diameter.

The cell size depends on the strengthened material. To secure the brick design, the wall length is 5 cm. For cement screed, these indicators will not be enough, you need to use smaller marking.

The estimated program is designed to design engineering systems for various purposes using in the design of technical insulation "K-FLEX", covering protective materials and components, based on the requirements contained in the norms of technological design and other regulatory documents.

To increase the strength of the foundations, monolithic structures and bases, fittings are used so that the design can experience significant loads in all directions. The most efficient option is a masonry mesh, the valve in which is connected by welding or loops. The diameter of the components may vary from 3 to 40 millimeters, the distance between them is from 0.5 to 40 centimeters. The weight of the reinforcement grid is the indicator necessary for the calculations, since the product is made of metal and significantly drags the design. Also, this parameter should be known when purchasing construction material and settlements with transport companies.

Today, all the necessary engineering operations can be made online, there is an assembly weight of the reinforcement grid. To maximize the accuracy of the result, it is proposed to make the following parameters:

the diameter of the longitudinal wire;
diameter of transverse reinforcement;
a step of longitudinal reinforcement;
pitch of transverse elements;
length and width of the sheet.

After filling out the forms, click on the "Run" button and all unknown parameters will be displayed in the table.

a, B and B - flat;
g - spatial;
d - spatial with a 1-tier cross section;
e - spatial with a 2-tier cross section;
w - curved products;
z - bent spatial;
and - mortgage elements.

Classification

Products for reinforcement are classified by several features:

Armature diameter and its location

the diameter is distinguished: light modifications with D wire from 3 to 10 mm and severe with D rods from 12 to 40 mm;
the location of the working fittings can go in 1 direction with the distribution - in another or - on both directions.

Marking

Purpose:

to enhance the foundation;
for road linen;
formation of interroom partitions;
for masonry work;
for plastering work;
alignment of the floor surface;
for installation of thermal insulation.

Standard dimensions

With the standard dimensions of the reinforcement material you can find the table below.

In the table you can easily find the necessary characteristics, for example, the weight of the 50x50 mesh mesh is 1.1 kg. But, if you do not have a computer with an internet connection or you prefer to make calculations yourself, this material parameter can be calculated by the formula.

Welding calculation

The calculation is performed in 2 stages:

We find the volume of 1 meter of material. Indicator \u003d 1 meter x (0.785 x D x D)
Calculate the desired parameter. The mass is set to multiply a specific indicator - 7850 kg / m3 per volume indicator.

Example of calculation

Consider how to use the proposed formula in practice. For example, we need to calculate the weight of the material for reinforcing with the diameter of the transverse and longitudinal wire in 0.012 meters. So, the volume is: 1 x (0.012 x 0.012 x 0.785) \u003d 0.00011304 m3. Now you can calculate the mass: 0.00011304 x 7850 \u003d 0.887 kilogram. If the table is at hand, it is advisable to verify the results for accuracy.

Calculation of the value of the reinforcement grid

To calculate the purchase price of the product for reinforcement, the resulting weight is multiplied by the cost of a kilogram represented by the seller. As a result of the calculations, you get the desired value. So, by simple solutions, you can quickly determine the required amount of reinforcement to perform specific work, make a purchase in exact volume and do not overpay for transportation.

Standard and non-standard execution

In addition to the foregoing, it should be understood that some manufacturers make materials for reinforcement of non-standard sizes. In this case, more complex formulas will be required to determine the weight, so such calculations better entrust specialists or use electronic mathematical tables. Also, some manufacturers produce material for reinforcing with anti-corrosion coatings. It has not only a longer service life, but a larger mass. For example, rods with galvanized will weigh more, in comparison with ordinary products. In such cases, you should use information from the product specification.

The weight of the reinforcement grid

Concrete casting used to create foundation bases in itself is a fairly durable design. However, its strength is large only in one direction - namely the concrete is well resistive pressure.

But loads in other areas can also work on concrete bases. For example, it may experience an effect on bending, twisting and so on. The soil is a non-uniform substance and when freezing can change its structure and volume, expanding in different directions. In order to give concrete casting strength and resistance to the effects in any directions - a metallic power frame is introduced into the body of concrete casting.

Metal frame in concrete castings is applied not only during the construction of foundations. It also is also created with other concrete work, for example, in the construction of stairs or when creating an aligning cement-sand tie.

Metal frame of concrete casting can be created in various ways. Thus, the spatial frame can be created from metal rods that bind to each other in the places of intersections. Fixed rods can be knitted wire, clamps or electric welding.

An excellent solution in the formation of a metal frame can be the use of reinforcement grid.

Reinforcement grid. Characteristics and examples of use

The reinforcement grid is formed from a metal wire or from the reinforcement rods of a larger cross section in industrial production. This achieves the accuracy of the sizes of the grid step, which has a positive effect on the general quality of the reinforced concrete structure.

In the process of its manufacture, the segments of the wire or reinforcement rods are laid out with a certain step, and then in places of intersection are fixed with point electrical welding.

The reinforcement grid is widely used in the construction industry, both for exterior and foundation and internal interior work. Laid in several horizontal layers in the foundation and connected by vertical jumpers - the reinforcement grid becomes an excellent power frame for reinforced concrete casting. The reinforcement grid, laid in one layer on the surface of the overlap, can become the basis for a floor screed or for fastening the warm flooring system with a liquid coolant. In addition, using the reinforced concrete structures, such as input staircases can be formed using reinforced concrete structures.

Types of reinforcement nets

Classification of reinforcement grids can be made by several parameters. First of all, it can be divided into types of the reinforcement grid based on the thickness of the source material used:

If the reinforcement grid is manufactured from a relatively thin metal wire - then it is conditional called "thin",
In the event that the reinforcement grid is made of a thick metal bar, it can be called "Tolstoy".

In addition, the reinforcement grid can be manufactured with varying degrees.

An ordinary welding accuracy may be distinguished, quite suitable for external construction work and reinforcement grid with increased accuracy. The accuracy of welding elements of the reinforcement grid is indicated by numbers after the letter "P" in marking.

Sample reinforcement grid

Separately, it is worth saying about how the reinforcement grid from industrial enterprises is supplied. Depending on the thickness of the elements used from the plant, the grid can be supplied in the form of flat plates or in the form of rolls.

In addition, depending on the purpose, the reinforcement grid can be manufactured with different cell configuration. They can be rectangular or square.

Flaps of reinforcement grid

Features of applying reinforcement grid

The reinforcement grid can significantly reduce the time to carry out construction work using concrete castings.

With a classic method of forming a power frame, it is created from individual metal rods. At the same time, the creation of a spatial frame seems to be quite complex. Each place of intersection of reinforcement rods should be bonded.

Fixation of places of intersection of reinforcement rods can be carried out with the help of hinges of knitting wire. It is twice, turns around around the intersection area and twists with a pointed hook or special automatic devices.

Naturally, such fixation can take a lot of time and effort. Therefore, in some cases, when conducting foundation and general structures, it is advisable to use the finished reinforcement grid.

Calculation of the weight of the reinforcement grid

The calculation of the weight of the reinforcement grid can be useful to you to determine the total weight of the building structure and for the calculation of logistics - that is, ways to deliver building materials to the construction site.
In order to make the calculation of the weight of the reinforcement grid First of all, it is necessary to know the diameter of the used metal rod or wire, the step between the wire or rods and the configuration of the cells.
So, a step between wire or rods can leave from 5 to 25 centimeters. When creating a reinforcement grid, it can be used as a wire with a diameter of 3 millimeters and the reinforcement metal bar with a diameter of up to 12 millimeters.
When marking a grid, standard designations are used that will help you calculate the weight of the reinforcement grid.
So, if the reinforcement grid is marked "150x150x5", it means that this product has a cell of the square configuration of 15 to 15 centimeters and is made of wire with a thickness of 5 millimeters.
In order to calculate the weight of the reinforcement grid, you can use the table shown in our article.

Table for calculating the weight of the reinforcement grid

Please note that different manufacturers can use and non-standard values \u200b\u200bof the reinforcement grid. In this case, it is necessary to calculate its weight individually, with the use of special formulas. The use of mathematical spreadsheets for such a calculation will be a good solution.

In addition, the reinforcement grid can be produced with different coatings. Thus, a number of enterprises produces a galvanized reinforcement grid. Such a grid has an incomparable longer service life and can also be used for external finishing works. For example, to create fences or fences.
