Dimensions and weight of the foundation blocks according to GOST , the use and characteristics

From the title it is clear that the products are used for construction of the building foundation.As a rule, most often, especially in the individual building, select the tape type of foundation, since it allows to equip a full basement, suitable for use in various applications.In addition, according to experts, the installation of the foundation blocks in the average cost of 2 000 rubles / m3 cheaper than construction of the formwork and pouring concrete monolith manufacturing solution.

When appropriate to apply

• the presence on the building site space.Blocks have considerable weight, and moving them by hand is not possible.Therefore it is necessary to use a crane.
• If time is short.Precast foundation mounted quickly, it is only necessary to prepare a place in the bookmark blocks.At the same time for the construction of reinforced tape base necessary to build a fence (formwork), produce Valve "skeleton", knead and pour the solution, to take measures for its heating and wait until the concrete hardens.
• when working in adverse weather conditions (for example, in the autumn, in the period of intense rainfall), which make it difficult to fill the production of foundation method.
• case of insufficient training of employees.The construction of the monolith requires knowledge and experience, and the installation of blocks in a trench complexity is not.
• If his performance tape will not be made continuous and discontinuous.This type of foundation provides additional savings on materials.

Features

blocks These blocks characteristics as size and weight are directly correlated.Their production is regulated by state standards.For example, for foundation products - GOST 13579 of 1978.

In accordance therewith, the length of the blocks is in the range 0.8 - 2.4 m;width of 0.3 - 0.5 m;height 0.3 - 0.6 m Weight foundation blocks -.. from 340 kg to 2 tonnes

All units have a name in line with the part number.For example, a product manufactured 8-3-6 with such characteristics (length x width x height) in "m" - 0.8 x 0.3 x 0.6.Estimated cost - 740 rubles / pcs.

It is clear that with such a designation numbers in the name of the product indicate its dimensions expressed in the "dm".The abbreviation stands for "F" - foundation;"B" - the block;"C" - continuous.

For example, a product FBS 05/03/24 corresponds to the size of 2.4 x 0.5 x 0.3 m, weighs 800 kg and is worth about 920 rubles / pcs.

are commercially available w / w foundation blocks of different manufacturers.Therefore, it may be slightly different as the sample size and brand of used concrete.

for M100 (Class 7.5) can be reduced following data:

• length - from 78 cm to 2.38 m;
• width - from 30 to 60 cm;
• height - of 30 or 58 cm
• Weight -.. From 320 kg to 1.96 t
• price within 445 - 2670 rubles / piece.

Recommendation

should try to use blocks of greater length.Then they reduced the number of joints, decrease the amount of work on the installation, sealing joints.And when you consider that you have to pay for each hour of use of the crane, it significantly reduce the cost of construction.
