reliable basis for any construction is the foundation.From the correctness of its devices, as well as accurate calculations at the design stage will depend overall stability and durability of the structure of the future.For these purposes, you must have certain skills in construction and extensive experience in the construction of these structures, which is not all there is.In this article we will talk, how to make the foundation and highlight some of the issues faced by many people in the initial phase of construction.

Calculation of the foundation under the house part of the project an ideal base

When erecting the house is worth paying attention to the nature of construction, that is the material from which it is made, calculate its total weight, analyze the nature of the soil and the soil, and only then chooseone or the other type of foundation and proceed directly to the calculations.

For light buildings are quite suitable columnar and melkozaglubolennye strip foundation

s.Multi-storey buildings, built of brick and concrete best place for a pre-arranged concrete monolith.

Depth of.This figure is based on the degree of soil freezing in the winter on a separate territory.For the central part of Russia, for example, this value is between 150 and 180 cm. The calculation of the foundation of its shallow depth should be no more than half this value.

to calculate the load on the foundation use special construction of the table, where painted as weigh different design house per 1 m3.This value will also affect both the penetration of a base and in its width.

Before you calculate the load on the foundation, it is necessary to evaluate the soil in the area in which you are going to carry out construction.Sometimes even the strongest monolith can not resist the natural processes in the soil.Therefore, carefully examine maps of the area, making the basis of their respective estimates.

calculation foundation rollover is to prevent it shifting under load of the building to the side, along with the ground.To this end, it should be possible to deepen, making desirable little more underground base its part protruding above the ground.

Generally, any base under load subject to shrinkage.In order to determine the calculation used for punching foundation.This figure depends on the size of the foot, and the nature of burial ground on which it is installed.

How to calculate the foundation for the house, especially the design.

proceed directly to design issues of a particular type of foundations.Calculation pier foundation is in the selection of thickness, width and penetration values ​​of individual poles, and the distance between them.If burial is necessary to consider the nature of the soil and the mass of the building.Typically, the distance between its elements is 1.5 to 2.5 meters, depth - up to 180 cm diameter poles - 40 cm.

If you choose the base for the house of the pile, the pile foundation settlement should start with itbearing members.They may be prefabricated or made on the construction site.As a rule, the load on a pile should be about 2 tons, this figure is calculated and the required number of them, as well as the location of a future home.

Strip foundation, calculation which are also subject to the indicators used for any type of foundation, has its own characteristics.The main task is to choose the width, which must be at least 10 cm more than the thickness of the walls of the future building.Its height is determined according to planning decisions at home, and the depth is selected depending on the characteristics of the soil and the presence of basement and ground floor.

When calculating the slab foundation of its depth should be at least 50 cm. The width and length is selected according to the size of the building.It is desirable to have within its structure at least two reinforcement zones connected in a network.The main indicator in the calculation is the amount of the pour of concrete per unit area.On average of 1 m3 is necessary to 2.5 tons of concrete.Multiply the height, length and width of the formwork 2.5, we obtain the required amount thereof.
