Frame: weight and length calculations in construction work

The capital construction of country houses of the monolith can not do without reinforced structures. The majority of costs in the purchase of materials mainly falls on the rebar. Material weight, calculated precisely and correctly, will really appreciate not only the cost of organizing the construction work, but also an important part of the cost of the entire facility.

The need for reinforcement of weight calculation: weight correspondence table and lengths

Armature - building material representing the set of certain metallic elements, intended for the construction of monolithic structure with cement mortar. It serves as a support for the retention of tensile stress and to enhance betonokonstruktsii in the compression zone.

Reinforcing components are mainly used in the construction of the foundation and erection of walls of buildings betonomonolita. Much of the time, effort and material costs in the construction of concrete buildings it is necessary to create a reinforcement, which is made of reinforced rods and nets. In order to avoid unnecessary costs should be possible to accurately calculate the necessary amount of material. We can not do without the knowledge of the weight of fittings in meter. Table weight relationships and length of different types of structures to help make the right calculations.

To calculate the weight of the valves, it is necessary to lay down the total length of all the bars and multiply it by the weight of one meter. All relevant data, taking into account the grade of steel and the diameter of the rods, leading to calculation tables. Also takes into account the brand of the material from which produce rebar.

Table armature mass: GOSTRegulating the quality of the goods

Indicator standard mass corresponding diameter valves regulate developed standards - GOST 5781-82 and GOST P 52544-2006.

Table weight per meter fittings, length and diameter of the rod guides you through the correct calculation:

The cross section of reinforcement, mm	The weight per meter, g	The total length of the reinforcement in a ton of material, m
6	222	4505
8	395	2532
10	617	1620
12	888	1126

55	18650	54
60	22190	45
70	30210	33
80	39460	25

Use this table is quite simple. The first column contains the data on the rod diameter, the second - the mass per meter of rebar concrete type. The third column is displayed overall length of the reinforcing elements in one tonne.

After studying the table, you will notice a pattern. The higher the valve diameter, the greater the weight meter material. The total length of one ton, on the contrary, is inversely proportional to the thickness of the rods.

Useful advice! diameter size to be recognized by the manufacturer. If measure its own, then it would entail an error in the calculations, since the surface of the reinforcing bar has a ribbed structure.

Thus, knowing the weight of the reinforcement according to GOST 5781-82, we can easily calculate the total coefficient reinforced structure, it is possible to determine the weight of the armature with respect to the volume of concrete required. Due to the presence of this data, we can easily calculate the total amount of material that will be required for the construction of concrete structures - whether the foundation or monolithic building. The amount of consumption of materials made from calculations cubic meter of concrete.

Specific weight of reinforcement: table according to the account square footage sold by the meter

Running meter of profile bar - a segment of the material length of one meter. It can be both smooth and textured surface. Mass rods, respectively, regulate their diameter. GOST set indicators from 6 to 80 millimeters. The basis material is taken periodic steel.

Weight of reinforcing mesh wire plaster reinforcement for the foundation of reinforced concrete, armosetki under brickwork depends on the dimensions of the webs, the area of ​​the cell and the diameter of the rods in millimeters. Reinforcing steel, produced in the domestic market, widely used in construction, different quality characteristics, meets all the requirements of guests at the metal.

Calculations performed using the above table reinforcement. Weight 1 meter depends on the external profile of the structure, which is corrugated or smooth. The presence of the ribs and the outside of the corrugations provides a more reliable coupling rods with concrete mortar. Thus betonokonstruktsiya itself in such a case has a high quality characteristics.

Properties technological process of reinforcing steel determine the entire assortment of fittings. By such indicators steel is hot-rolled or cold-drawn wire rod.

Armature produced in accordance with GOST 5781-82 - it bars with smooth surface class as well as profiles of periodic steel grades from A to A-II-VI. GOST 52544-2006 - it profiles A500C classes of periodic and B500C steels intended for welding. The letter A and marked hot-heat strengthening reinforcement, the letter C - cold-material, with the letter C - weldable rolling.

Marking material, the weight of 1 meter: table assortment

If we take the basis of the mechanical properties of reinforcing steel, such as strength and weight, then material is divided into separate classes mix with a specific designation of A-I to A-VI. The weight meter fittings hot-rolled steel not depend on them.

Value class mark diameter and amply demonstrated in the table:

Steel grade according to GOST 5781-82	The diameter of the rod, mm	Steel grade according to GOST P 52544-2006	The diameter of the rod, mm	Brand reinforcement
A-I	6-40	A240	6-40	St3kp, St3ps, St3sp
A-II	10-40	A300	40-80	St5sp, St5ps 18G2S
Ac-II	10-32	AS300	36-40	10GT
A-III	6-40	A400	6-22	35GS, 25G2S 32G2Rps
A-IV	10-32	A600	6-8 36-40	80C 20 * 2 Hz

A-VI	10-22	A1000	10-22	22 2G2AYU *, 22 * ​​2G2R, 20 * 2G2SR

If we take, for example, the valve class A-III, then it is used to strengthen the foundations of concrete buildings erected in a short time. Mass valves in this case is equal to the total weight of the steel frame, including foundation, walls and concrete floors, as well as the weight of the welded mesh, concrete is poured.

The diameter of the rebar in the range of 8 to 25 mm is considered the most popular size profiles in the construction market. All domestic fixture before hitting the metal bases are quality controlled steps to guarantee its compliance with GOST.

Reference! Displacement of the steel rod is calculated by multiplying the square footage on the geometric area of ​​a circle - 3,14 * D * D / 4. D - is the diameter. Specific reinforcement weight - 7850 kg / m³. If you multiply it by the amount, you get an overall specific gravity of one meter fittings.

Frame: Weight and various embodiments thereof calculation

reinforcement weight is calculated in different ways:

• According to the normative weight;
• taking as a basis the specific gravity;
• using an online calculator.

The required number of rods regulatory weight is determined using the weight of the table above in relation to the meter. This is the simplest version of the calculation. For example, we calculate the weight of reinforcement 14.

The main condition of such calculations - the matching table. Calculation process itself (in the preparation of the construction plan view of the construction of reinforcing mesh) comprises the following stages:

• select the appropriate diameter rods;
• calculate the yardage required reinforcement;
• multiplied by the weight of one meter diameter corresponding to the number of required valve rods.

For example, for a building to be used 2300 meters armature 14. Weight 1 meter bars was 1.21 kg. We perform the calculation of 2300 * 1.21 = 2783 kg. Thus, to perform this amount of work required 2 tons 783 kilograms of steel rods. Similarly calculated number of rods of diameter corresponding to one tonne. The data is taken from the table.

Calculations for a specific weight per weight calculation example valves 12 meters

The method of calculations by specific weight requires special skills and knowledge. At its base laid formula for determining mass using quantities such as the volume of the object and its specific gravity. This is the most difficult and time-consuming option of calculating the weight. It is applicable only in cases where there is no table available with the standards and is a possibility to use an online calculator.

Visually examine these calculations can be for example, determining the weight of 1 meter valves 12 mm. First we need to remember the formula for calculation of the weight rate of physics, according to which the mass is equal to the volume of the object multiplied by its density, i.e. the proportion. We began this figure corresponds to 7850 kg / m³.

Volume determined independently, given the fact that the valve rod has a cylindrical shape. In this case, useful knowledge of the geometry. The formula reads as follows: volume of the cylinder is calculated by multiplying the cross-sectional area at the height of the figure. In the cylinder section - it is a circle. Its area is calculated by another formula where a constant with a value of 3.14 pi multiplied by the radius squared. Radius - is known to half the diameter.

The order of weight calculations valves 12 mm per meter, the length of the entire rod

The diameter of the rebar taken from the planning and building settlements. Independently of its best not to be measured in order to avoid errors. Determine how much weight one meter valves 12 mm. Thus, we conclude that the radius is 6 mm or 0.006 m.

Useful advice! The easiest way to settlement - using special software (or online calculator). For this part of the cell mass is introduced data reinforcement in tons, and the number of the profile rod length in millimeters. Standard length rods - 6000 or 12000 mm.

Sequence independent calculation using the following formula:

1. Determining the area of ​​a circle: 3,14 * 0,006² = 0,00011304 m².
2. Calculation of the volume meter rods: 0.00011304 * 1 = 0.00011304 m³.
3. Calculation of weight valves 12 1 meter: 0.00011304 m³ 7850 kg / m = 0.887 kg.

If the result is checked against the table, we find compliance with national standards of data. If you want to calculate the mass of a particular rod, the area of ​​a circle is multiplied by its length. In general, the same algorithm calculations.

Full procedure for calculating the weight of 1 meter of reinforcement 12, represented by the mathematical expression will look like this:

1m * (3.14 * * 0,012m 0,012m / 4) * 7850kg / m = 0.887 kg.

The result is identical to the previous one. Depending on the length of the armature corresponding value substituted into the formula and calculate the weight of it. Calculate the weight of the grid is possible by multiplying the value obtained for 1 m², the desired number of square meters reinforcement.

calculation of the weight of the reinforcement wire in square meters

Reinforcing wire meets the requirements of GOST 6727-80. For its production using low-carbon steel. Diametrically value ordinary wire - 3, 4 and 5 mm. Range has two classes: B-I - with a smooth surface and Bp 1 - Material from periodic profile.
