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 on concrete bases Loads in other areas can also be influenced. 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 different areas. 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 different 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.
Excellent solution when forming metal carcass It can be the use of reinforcement grid.
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 reinforcement grid, you can form and complex durable reinforced concrete structures, for example, entrance stairs.
Reinforcement grid - Photo 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:
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.
Separately, it is worth saying about what form the reinforcement grid is supplied with industrial enterprises. 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.
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.
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. Good decision There will be use for such a calculation of mathematical spreadsheets.
In addition, the reinforcement grid can be issued with various coatings. Thus, a number of enterprises produces a galvanized reinforcement grid. Such a grid has an incomparable longer service life and can be used for outdoor finishing work. For example, to create fences or fences.

The weight of the reinforcement grid
Learn more about how to determine the weight of the reinforcement grid, and the calculator will help you make a calculation.
With the help of this calculator, you can produce online calculation of the weight and cost of the rectangular reinforcement grid . In other words, by setting the diameter of the reinforcement, the length and width of the mesh, the pitch of the reinforcement rods in the same direction, the price of the valve for 1 ton, you can learn indents (the distance between the edge of the grid and the first rod) and the number of rods in both directions, as well as mass , length and cost of the grid.
In case you have a few identical reinforcement grids, then sets the number of grids in a certain column, you additionally, you can calculate their total weight, length and cost. When one grid is considered, then the figure "1" is set in this column.
As for an additional percentage, then in this graph you put such a figure as you would like to purchase fittings anymore. This percentage is always taken into account when the reversal of reinforcement is meant. And usually it is 5%.
Note: The calculation takes into account weight 1 perm. Armatures according to GOST 5781-82 * and GOST R 52544-2006.
Calculation of the weight and value of the reinforcement grid
By building buildings from a monolithic reinforced concrete, you need to pay a maximum of your efforts to assembling a high-quality reinforcement frame.
Without an internal reinforcement grid concrete construction It remains fragile and does not work on bending. Reinforced concrete carrier element is different more high levels Sustainability, quality transmission quality, etc.
Grid for reinforcement of the foundation from fittings
In this article, we will talk about how and why the reinforcement frames are collecting, which gives us reinforcement, which role is played by the calculation of reinforcement, as well as this very calculation of the reinforcement.
The calculation of the number of reinforcement for the foundation or any other carrier structure is performed in a strict sequence. It is unacceptable to refuse this operation.
At the same time, it is necessary to clearly understand why reinforcement is generally necessary, what advantages it gives, etc.
The reinforcement frame for a tie of the floor, the foundation (ribbon, slab, silent-woodworked), columns, walls or overlaps, protrudes a kind of skeleton.
Armature tightens the concrete, increases its rigidity and limit of operational capabilities. If there are at least one rod for 10 square centimeters of concrete, its stability increases several times.
Moreover, the indicators are increasing both standard and side. If you use the correct reinforcement scheme, the monolithic concrete can be used when building any home, ranging from small low-rise buildings, and ending with high-rise building, where the house scheme provides for the giant structures with a height of several dozen, if not hundreds of meters.
At the same time, if you calculate all expenses, you can understand one simple thing - even if to strengthen carrier structures There are a complex scheme consisting of a variety of elements, the cost of the design will eventually remain acceptable.
1.1 Construction and Scheme
For reinforcement of each design, some particular scheme is applied. The reinforcement scheme is the principle and rules by which the elements of the frame and the grid are collected.
Foundation reinforcement frame
W. different designs It is different. Accordingly, for different designs at home you need to think through different methods Calculate how many materials and weight are needed to create a particular framework.
Reinforcement mesh diagram affects:
The grid circuit of any base consists of a transverse and longitudinal reinforcement laid in a certain sequence with a specified step.
Rods of transverse and longitudinal reinforcement are associated together using wire or clutches.
The wire should be used when it is necessary to connect the nodes of the transverse and longitudinal reinforcement of the brass, and the clutches are intended to eliminate the rods.
Wall reinforcement formwork belt Fundament
Any framework consists of a properly laid longitudinal reinforcement, tied up additional transverse. Such a gleaming allows you to create one of the frames of the frame. Further, these marines are permissible to use as its main components.
If, for example, we consider the frame of overlapping at home, here you need to connect only two levels of the grid: lower and top.
For the designs of the walls of the house or ribbon foundation, two or three-level meshes are used, attached to the transverse face in the form of a frame of ribbon base pillows.
For the columns of the pile foundation or carrier structures of the house, rectangular oblong frames are formed, where the role of transverse reinforcement is reduced to the dressing and stabilization of the overall design.
1.2 Used Armature
The calculation of the fittings for the foundation is carried out in order to be able to calculate its future expenses, and also to determine exactly what particular products we need.
As we noted above, different schemes provide different types Frames. The frame of the ribbon foundation is not similar to the frame of the pile, and the one, in turn, does not look like a fire frame.
Accordingly, the reinforcement itself in them should be used different. What exactly depends on the features of the house. However, we can allocate several main advice.
When selection of fittings, it is taken into account:
The diameter affects how many loads will be able to transfer the rod without deformations. The larger the diameter strong construction. The larger the diameter, the greater the price of the rod and the indicators of its mass.
As a rule, in frames, the reinforcement, the diameter of the cross section of which begins from 8 mm and reaches 25-30 mm.
Reinforcement rods 18 mm thick
The diameter of 8-12 mm is suitable for low-loaded frames of the frame. For example, for the device of transverse reinforcement during the reinforcement of the columns of the pile base, the device of the upper mesh of overlaps, tape basement, etc.
The diameter of the straighter is more than 15 mm involves it installation in workers loaded frames, somehow the bottom grid of overlapping, the base of the ribbon or scatter of the pile foundations, etc.
The builders are trying to combine the working diameter of the rods so that it is nowhere to reset the stick. Because in fact, the calculation of fittings for the foundation and is carried out. It allows you to optimize the construction process and significantly reduce extra costs.
The calculation itself is divided into 2 stages: the stage of calculating loads and quantity.
The first stage makes it possible to understand how much loads takes on the design, how much it will endure weight, what should the reinforce framework should be, which rods should be used in it and how many of them should be.
The second stage is the calculation of a specific number of reinforcement on a predetermined scheme.
The first stage, as a rule, delegate specialists. Newcomers or people without experience make the calculations of loads are not recommended. Exceptions concern only small bearing structures.
For example, if you are interested in reinforcement of a column foundation for an extension, cottage, remote kitchen, etc. Reinforcement of a column foundation, carrying a load from such small structures - non-critical.
Another thing, a reinforcement frame for the foundation of the capital structure, or any other design. Here is a similar eye, a clear understanding of the goals, the nature of the actions of carrier loads, etc.
You can also use the calculator for the calculation of loads. This calculator is found on the Internet on most construction sites. However, the calculator only gives a general presentation. Calculations that the calculator will provide you with accuracy and quality will not be compared with the calculations from the experienced proven of the specialist. Yes, and no calculator will give you a guarantee if you entered the wrong parameters in its fields, then the result will get similar.
For which a calculator can be used is to calculate the number and cost of reinforcement. That is, when working with the second stage.
2.2 Calculation of quantity
After calculating the loads, you already know, from which valves you need to create one or another element of the frame, with what step to collect grids, etc. What you do not know is the exact number of reinforcement. However, these knowledge is necessary.
You must come to the store and call some particular figure to the seller, and not just show the seller documents with incomprehensible formulas.
Knowing all future frame parameters, its carrier loads and an approximate level, to determine the exact amount of material for reinforcing ribbon or pile foundations will not be difficult even newcomer.
To do this, you need a regular calculator and several sheets of paper.
2.3 Example of calculating the design of the structure
To begin with, consider the principle of determining the number of reinforcement of the pile base.
The design of the pile foundation consists of columns and woodwork. The reinforcement for the columns is quite easy. It is enough to know the number of longitudinal thick rods per column.
Then we calculate the transverse fittings. Cross fittings fixes longitudinal. It is enough to find out the distance between the thick longitudinal reinforcement and its length. The bandage of the transverse rods of the columns is carried out in increments of 20-30 cm, respectively, to determine the specific values \u200b\u200bwill not be difficult.
The calculation of the design of the ribbon foundation is somewhat more complicated. For a belt base, the presence of several planes is characterized. However, we will look at its basic performance, in the form of a tape without soles.
The tape in this case knits from two parallel mounted frames, pulled by transverse reinforcement. The number of rods on the frame depends on its size, as well as the selected step.
If, for example, the wall of the belt base has a length of 10 meters, and the reinforcement step is 30 cm, then we obtain 10 by 0.3, we get approximately 34-35 rods. So much material it will take to form one of the parts of the grid.
Lower reinforcement mesh in the formwork of overlapping
As we see, it is enough to use the simplest calculator to use for such calculations.
Calculation of overlaps is performed similarly, only there are 2 levels of the grid. The lower level is made of thicker reinforcement with a big step, and the top of the thinner, with a smaller step and does not cover the entire overlap area.
The principle of determining the number here is similar. We divide the length of the plate on the pitch of the reinforcement, then produce similar steps with a width. Two digits as a result we add and get the total number of reinforcement on the bottom grid. Then, according to the same scheme, we consider the upper, and the case is done.
The reinforcement grid is a building element made from a special corrugated wire, which is fixed with welding at the intersection points to form characteristic square cells. Who at least once saw no longer confuses. The grid is designed for reinforcing elements from concrete and serves to ensure the strength of the entire design.
Made a welded mesh made of metal rods, the total diameter of which is 3 to 40 mm. Divided into light and severe species, while the first possesses the diameter of the rod up to 10mm., And the second from 12mm. respectively.
Considering the sizes of their cells, the naked eye can be noticed the difference that is from 0.5 cm and comes to 2.5 cm.
The reinforcement grid can be made of a large area and reaches length in 12 meters, P. minimum meaning from one meter. Maximum envelope width is 240 cm, with minimal value at 50 cm.
Table of geometric characteristics of welded grids TU 14-4-1284-84
Types of reinforcement products:
d, E. - Spatial frameworks of brazier and 2-way cross sections, respectively
z. - spatial frame bent from grids
The reinforcement grid is divided into two main subspecies below:
1. According to the original location of working fittings.
Working reinforcement is in one direction, and distributed in another (workers can be both longitudinal and transverse stripes).
Working reinforcement is made in both directions.
2. P. diameter Vertical and horizontal rods.
Hard species include meshes with a diameter over 12 mm. The lungs include all other grids that are in diameter. from 3 to 10 mm inclusive.
In order to increase the service life, this construction element can be galvanized or processed by polymers that carry a protective function and prevent corrosion formation.
At the moment, a single standard label is adopted to designate the types of reinforcement:
Ai. (hot rolled smooth, Roman figure I denotes strength level)
AII, AIII, AIV. AV, Avii. (hot rolled ribbed)
AT III, AT IV, AT V, AT VI (hot-rolled thermally hardened)
IN 1 (cold-rolled with a round cross section)
BP-1 (cold-rolled with periodic profiling)

If there are no tables at hand, the weight can be found by simple calculations.
In brackets area surroundings. D. - diameter.
In order to gain weight, you must multiply the volume on the proportion.
Example of calculation
We consider volume: 1 m x (0.785 x 0,012 m x 0,012 m) \u003d 0.00011304 m³
We consider weight: 0.00011304 m3 x 7850 kg / m³ \u003d 0,887 kg
The result obtained above will be identical to the table data that can be used as part of "work on errors".
Also, it is also impossible not to mention a specialized online calculator " LotServiscalc.". A convenient service allows you to get data literally in several clicks. It quickly calculates weight not only for the reinforcement grid, which is marked as welding, but also for any other.
The reinforcement grid provides a multiple increase in the strength of any design, which involves its use. The key tasks in construction are the reinforcement of the foundation and the acquisition of greater strength walls - the creation of a kind of wall frame. What provides the long-term operation of the entire structure.
Reinforcement of rapidly destroyed roadbed.
For reinforcement with masonry work.
To enhance the foundation.
To increase the characteristics and strengthen thermal insulation.
For leveling and maximum strengthening of the initial flooring.
To strengthen walls when working with plaster.
It is also used in the field of the manufacture of partitions both in private houses and apartments.
Non-standard use of material:
Gol on the fiction of the cherry. Surely you themselves have repeatedly noted the reinforcement wire used at all for reinforcement. As a rule, this happens when a roll remains after construction and you need to put it into the case. Here are some examples:
Some craftsmen use fittings when erending cells for pets.
And also use the reinforcement grid for making a variety of small parts in the form of mousetrap or feeders (a special feeder for fish).
When nothing was better in hand, it is used as a barrier for ventilation pipes and holes.
Cement mortar can be made more fat, that is, more plastic and convenient to work. To do this add to it detergent - Mandatory on the basis of soap, like "Fairi", not a synthetic detergent.
