The foundation is the main attribute of any structure. It is also a kind of support, on which the success of construction depends on seventy percent. It is from the laying of the foundation that any engineer-builder begins to directly build a new building. To make the right choice of the foundation, you need to know which device you need. It is necessary to pay attention to some features:- take into account what loads will be transmitted to the foundation of the building;- what type of soil will be used;- it is necessary to determine the depth of freezing of the earth in the location of the development;- at what depth there are groundwater occurrence; if we talk about the loads, then First you need to know that they are constant and temporary. The constant loads of the foundation include the weight of the future structure and operational loads. The category of operational loads includes the weight of furniture equipment, people. The temporary loads of the foundation of the building include a layer of snow on the roof of the building, wind impulses, heavy rains. After determining the load and other parameters, you should decide which foundation to lay. To date, the following types of foundation are known in construction:- strip reinforced concrete foundation;- strip monolithic foundation;- foundation of monolithic plates. The basis of the belt reinforced concrete foundation is concrete preparation, which has a thickness of 100 millimeters. The foundation of monolithic plates implies the use of a monolithic reinforced belt, as well as an elaborate reinforced concrete plate. The calculation and design of the foundation must be made depending on the relief of the area where the building will be built.
