What is and how to build the foundation of their own hands columnar

foundation called that part of the building, which takes up the entire load structures and transmits it to the ground.From the strength of the foundation depends on the stability, strength and durability of the whole house, so it's important to choose the right type.

One type of foundation is a bar.His device is useful when you want to deep foundations and other foundations, such as tape or slab, are too expensive option.Usually pier foundation under the light suit, one or two-storey buildings made of wood or brick.

Arrange the foundation with his hands columnar or any other thing, though not easy, but it is feasible, it should only become familiar with the technology of construction.

design Stolbovoye foundation is the construction of separate, unrelated posts under major construction sites - under the angles of the perimeter of the building, the intersection of walls, under the piers, and other points of large concentrated loads.As a rule, building a foundation with his hands columnar, the distance between the elements to make 1.2-3 m. Erected poles stacked strapping beams, which, in fact, begins masonry walls.

Raising his hands columnar foundation may be used for this purpose the following materials: rubble concrete, concrete, bottles flagstone, natural stone or brick.The dimensions depend on the material of the pillars of manufacturing foundation structures and sizes of the material from which it is constructed.

From the foundation to build a pole with your hands, you should know the exact dimensions of the building and its interior layout, ie the arrangement of load-bearing walls and partitions.The first thing you need to make on the site layout, this tape are measured the length of the walls, in the center of the alleged pillars hammered pegs mandatory verifying diagonally to avoid skewing and ensure that all corners of the magnitude of 90 °.

Furthermore, building a foundation pillar with their hands, how to work you need to drill to dig under each post a small pit.Its depth depends on the depth of frost penetration in the region.For example, if this value is 1 m, the depth of the hole should be made 1.2 m, its width is independent of the parties section column.Each recess dug need to clean up the wall, lay them on the sides of the waterproofing layer, and you can use the usual roofing material, and on the bottom pour a small sandy base that recommends a well compacted.At the center of the future pillars set some reinforcement rods, which should protrude above the ground before the expected height of the element.

next step is pouring the concrete recess prepared to the level of the ground, and then around each pillar should arrange the formwork.It can be wood or metal, collapsible or monolithic.Concrete should be taking the high mark, and with preparing the concrete mix, make sure that the cement has a mark not less than 400. If desired, the foundation can be columnar their own hands to build of brick in cement mortar, with the obligatory ligation of the sutures.

The main thing in the construction of this type of foundation, it is necessary to adhere to the iron rule: the height of the bars must be horizontal verified, it is possible to use water-level regulation and produce not only the neighboring bollards, and on a diagonal.

can, as permanent formwork, used asbestos cement pipes.In this case it is mounted on the bottom of the recess, to carefully calibrate the vertical and the whole height of the column filled with concrete, it is well tamping.

Ready poles should be left to the concrete has set for at least a month, covered by sediments.

Before the construction should make the calculation pier foundation.Independently do this is unlikely to happen, since this procedure is quite laborious and requires some special knowledge in general, it includes the following stages: determining the nature of soil and special tables to find the value of the maximum permissible load, then the calculated weight of all home designs and determination of the area of ​​maximumload points.Then, the most important weight is divided by the load capacity and, ultimately, get the value of the area of ​​support of the foundation.Typically, for reassurance, thereto was added an additional 40% of the value.But this simplified scheme as making payment pier foundation is taken into account more concrete grade, the number of valves and some other necessary parameters.In any case, it is not necessary to engage in the foundation of their own calculations, for he is the most critical part of the construction and error in its calculation can be costly too.
