Individual developers often prefer the foam blocks, as this artificial stone allows you to save significantly on building materials. We wrote a lot about all its advantages and features of the masonry, and it's unlikely that anything completely new will be added. But here on the sizes of blocks it is necessary to stop all the same more in detail. Why do they need to know?
Firstly, , in order to fully understand the required volume of the purchasing lot, as the correct compilation of any estimate assumes, among other things, a reasonable optimization of costs. Especially, if it is a question of own purse.
Second , to determine the number of machines( flights), sufficient carrying capacity of machinery. Penobloks can not be transported by private transport, and renting a "board" depends on the type of car, and on the time of its use( as a rule - payment by the hour).
Previously, products were produced in accordance with a single standard:
- length( D) - 400,
- width( W) and height( B) - 200( mm).
Now the range of products is somewhat wider, especially since all the "bricks" are divided into several types, depending on the features of the application( installation site) - wall, partitions, for load-bearing or non-bearing structural elements. Enumerate all the types of foam blocks is not worth it, as there are quite a few of them, and the application depends on the method by which the masonry is carried out - by "landing" on the adhesive compound or on the CSP solution. In addition, there are differences in 1 parameter when the other two are equal.
It is enough to indicate that only by the height of the foam block( with the use of glue) there can be 7 positions( depending on "Ш" and "Д").A total of about two dozen. Those who wish to familiarize themselves in more detail can refer to GOST No. 21520 of 1989.
In practice, a private developer is unlikely to calculate everything to "mm."Yes it does not make sense, because technological errors depend entirely on the professionalism of the master, first of all, on the thickness of the fastening layer, which he puts( solution or glue).
It is possible to be guided by such( averaged) data( linear dimensions of standard foam blocks in "mm"):
- for bearing( external) walls - D = 600 x 300 x 200( 23.4 kg).When building internal, the same "bricks" are used, only they are put "on the priest".In this case, "Sh" turns into "B"( 200);
- for non-load-bearing( partitions) - 600 x 300 x 100( 11.7 kg).
These parameters are the most common in individual construction. In addition to the standard sizes, the volume of one foam block is also important. It is 0.036( for the "carrier") and 0.018( for the dividing wall) m³.On 1 pallet of blocks of the first type 40 pieces will fit, the second - 2 times more. How many blocks of different size in cubic meters - see here.
What to take into account
When determining the required number of foam blocks, it is necessary to slightly increase the calculated values (make the recommended "corrections").For what? First, in the process of transportation to the facility, certain products will be damaged( approximately 2.5%).Secondly, some of the "bricks" will have to be cut off, adjusted to the place of masonry( much depends on the architecture of the structure).This is given another 3 to 5%.In this regard, experts recommend buying foam blocks with a margin of about 10%.
Artificial stone is loaded into the machine on pallets. These devices are reusable, so they should be returned to the seller. But since not everyone does this, or they are brought in such a condition that they are unsuitable for further exploitation( and sometimes they are not subject to recovery at all), then when purchasing building materials for pallets, they will have to leave a cash deposit which can only be collected back after they have been returned.
