Interconnection of external and internal components of building materials
More details on how to carefully calculate the load from the replacement of the pipeline to the building, read below in the article. This will not require a special education - enough care.
As already mentioned, the density of the profile pipeline is 7.8, the volume of used metal can be fluctuated, which is clearly prescribed in the state standard. If the metal consumption for fabrication of the material is less than planned, it is better not to use such building material for installation indoors.
Still, in order not to make a mistake in buying, the buyer needs to freely navigate, know the formula and do calculations of the weight and length of the profile system.
Weight formula of profile systems
To calculate the weight, it is necessary to use multiplication in the formula. First, we multiply the volume of the material by its density( constant value 7.8 cubic meters).So, we are counting:
M.P.= S * 2 *( A + B) * p.
We remember the lessons of physics:
- S - wall thickness,
- Аи B - length of the prodil,
- р - density( 7.8 cubic meters).
Determining the volume of the
pipe There are several ways to calculate the volume:
- We consider the difference between the volume of a metal pipe of the same dimensions and the volume of the internal cavity.
- We calculate the volume of the sheet spent for the production of
- Let's sum up the volume on each side of the finished product.
The first method was most widely used. For this it is necessary to take a section of the profile pipe, determine its length, measure the external dimensions of its height, width and internal parameters of the same values. Then multiply the outer width, height. The result will be equal to the volume of the whole metal tube.
It is necessary, among other things, to multiply the inner height and width. This will be the volume of the internal space. The difference between the volume of an integral metal system and an internal space is called the volume of metal in the profile pipe. A similar formula for calculating volume is very clear and effective.
Well, at the very end we will reveal to you a terrible secret: there is a simplified formula to estimate the weight of the profile pipe, equal to 1 m. Although, here you can even do without formulas - you just need to read the table.
Other calculation methods for
For other methods of calculating weight and volume, you can always refer to the special document "State Standard 8639-82".A complete list of values of the mass of a 1-meter pipe segment, calculated each type of assortment of profile building materials. See the table for the values.
The value of the mass of a meter section of the profile pipe should be multiplied by the length of a meter length of the product.
