Rifle foundations
A screw foundation is widely used in the construction of suburban private houses, especially if the construction of the house is carried out on complex and very unstable soil. At the same time, the piles themselves can have different sizes. It's no secret that the foundation, no matter what type it is, is always subject to shrinkage. So, before starting to build the foundation, you need to carefully calculate everything, taking into account not only the features of a particular soil, but also the potential load provided on it. The calculation of a screw foundation is made in three stages. The first stage: the screw piles of the grillage for strength are calculated, taking into account the materials from which the piles are made. The second stage: the bearing capacity of the soil is determined. At this stage, it is very important to consider the features of the climate of the area where construction will be carried out. If the house will be built in the territory where cold winters and frequent minus temperatures, this circumstance, certainly, should be taken into account when calculating. The third stage: the final calculation of the foundation and the determination of its bearing capacity. Here all the factors that can affect the degree of shrinkage and strength of the future foundation are taken into account. The screw piles are often installed at a great distance from each other (about 2-3 meters), it is impossible to exclude the fact that when subsequently carried out construction work, The structure can give an uneven shrinkage. As a result of this, when calculating the screw piles, first of all, it should be taken into account the load that the future building will be provided on the piles. In the event that it is presumably, the building is constantly subject to significant wind loads, then the figure obtained as a result of calculations should be increased at least than 20%. Some builders prefer to increase the load by 30%, for safety. This provides the necessary margin of safety, which is able to block all those inaccuracies that are very difficult to avoid. With regard to calculating the foundation, it is better to show excessive caution than something to be unreasonable. In addition, if the building of the building provides for an internal supporting wall, which is forced by beams of ceilings from all sides, calculating the foundation, will not be superfluous to reduce the step between the screw piles under this wall by at least 30%. pin up casino
