The weight of the reinforcement is a very important parameter and for the construction of reinforced concrete structures, and for the construction of various buildings (for example - greenhouses). The mass of metal elements should be taken into account when planning the construction of the building itself. It depends on the calculation of the number of reinforcement rods in free and intense zones, the distance between the rods, etc.
In addition, the weight of the metal stroke will depend on the weight of the metal stroke. Cheaper to purchase metal rods on wholesale bases, where the price is indicated by ton. Calculation in construction is made in the route meters. Therefore, it is important to be able to calculate how many rod meters in one ton.
1 Matching Matching Figure Weight for Different Diameters
The standard mass of the valves of one or another diameter is governed by the standards GOST 5781-82. Table of standard calculations of magnitudes looks like this:
This table is absolutely easy to use. In the first column, select the diameter of the rod in mm, which will be used, in the second column immediately we see the weight of one rod rod of this type.
Third column shows us the number of stream meters of reinforcement in one ton.
1.1 Calculation of immature weight
The first and easiest way to find out how much the meter of reinforcement is weighted - the use of an electronic calculator for similar calculations.
To work with it, it is necessary to know only the diameter of the rod with which we will work. All other parameters of calculations have already been laid in the program.
Two other ways to learn How heavy the meter of reinforcement, more complicated. Consider them in order of increasing complexity.
Since in private construction, fittings with a diameter of 12 mm and 14 mm are most often used, we take such rods as a basis for calculations.
1.2 Example of calculating the weight of the reinforcement (video)
2 Calculation of regulatory weight
Calculate the number of reinforcement, The desired for construction (provided that we have a table at hand).
- Make a plan for building a building, taking into account the creation of the reinforcement grid.
- Determine with the diameter of the rods.
- Calculate the number of reinforcement used in meters.
- Multiply a mass of one meter of fittings of the desired diameter by the number of rods used.
Example: For construction, 2322 meters of reinforcement rods with a diameter of 14 mm will be used. The weight of the circuit meter of such rods is 1.21 kg. We multiply 2322 * 1,21 we get 2809 kilograms 62 grams (grams can be neglected). For construction, we will need 2 tons of 809 kilograms of metal rods.
2.1 Calculation by specific mass
This method of calculation requires certain knowledge, skills and labor. It is based on the mass calculation formula, in which such values \u200b\u200bare used as the volume of the figure and its share. Resort to such a method for calculating the route of reinforcement It is only possible if there is neither an electronic calculator, no table with GOST standards.
