For structures and buildings with small sizes, the main criterion of which is the height (and, kurs, configuration) WAND (for frame buildings and structures) width of the span, the foundation of the strip little -deep -over .
If the height is less than 5 meters for the construction of a straight line (and for tent or arched type buildings this height can be significantly larger), and for the frame building a span width is not more than 15-18m, then this is the cheapest cost, but not thereby less completely reliable option. Typically, the tape is buried at 200-400mm, its height is 300-600mm, and the width is usually 300-400 mm.
In order to calculate the volume of concrete, it is necessary to multiply the perimeter of the structure by the cross -sectional area of the tape . The degree of reinforcement, as well as the scheme, are determined by calculations, which are approximately 40-70 kg. AUF 1 cubic meter.m. Concrete. Sand-gravel mixture or just sand, pour 200-300 mm under a tape and tampedly tamp . This tape quite carries the building, and reinforcement serves to protect against cracking concrete in the rainy season, when the tape, and the entire structure, can swim slightly slightly. At the same time, it serves as a basement, on it you can build enclosing wall structures – whether it be a beam, panels or brick, depending on geological conditions, in some cases, waterproofing (coating or layered) of the strip foundation may be needed.
But nevertheless, if the structure has large sizes (for example, height), and, accordingly, a huge weight (say, a building of 2-3 floors of brick and above)-you need to make the foundation deepened strip string . This foundation requires more accurate and thorough calculations (of course, you can take with a margin, and then this can be very much affected by the price). The deepening is made to the depth of freezing in this region, for the production of construction. In Central Russia, for example, (including Moscow and in neighborhood), freezing depth is 1.6m. This means that in no case should you deepen the foundation less – because it can lead to the fact that your foundation in the winter will raise it with freezing soil water, and very significantly. And besides – in different places in different ways. The structure is skewed. Of course, soils are of varying degrees of heaving and wintering in frosts are also all different … But after starting the construction of the building, it is necessary to think seriously and calculate not relying on.
