The claimed invention "Method of Foundation construction" relates to the field of construction and serves to build the foundations for a low-cost residential houses, for example, in rural areas, rural intelligentsia and national projects, such as "Affordable housing".

There is a method of constructing a modular Foundation that is implemented during the construction of the Foundation for Russian patent for invention №2094568, IPC E02D 27/02, publ. 1997.10.27, which includes the construction of the underground part in the form of pillars, which perform the shifting, and the ground part, which is done in the form of beams dual console followed by the formation of the ground part.

The disadvantage of such a method of construction of the modular Foundation is its high cost.

This disadvantage is due to both high cost shifting poles, and the high cost of the method of installation.

There is a method of Foundation construction, including installation of the unit, under the soles of which have consistently slanted palusalu, and reinforcing structures, which is done in the form of a reinforced concrete frame, made in the form of two ground plates of rectangular cross-section, which are placed along opposite sides of the block, while the upper ends of inclined Prospal rigidly connected to the ledge. The method is implemented in the RF patent №208282, IPC E02D 271/00, E024D 27/08, publ. 06.27.1997.

The disadvantage of this method of Foundation construction is the high cost and complexity of erection of such constructions of the Foundation due to the high Materialien bone, in particular of metal, duration of erection of such constructions and low performance.

This disadvantage is due to the fact that these foundations have a high cost due to high metal consumption, requiring appropriate equipment for their installation, which is unacceptable in the construction of housing for people with low income, such as rural intelligentsia, in addition, high intensity gives additional bridges and reduces the performance of the constructed Foundation.

The closest technical solution to the claimed invention is a method of construction of the Foundation, implemented in the RF patent for the invention №2062832, IPC E02D 27/01, publ. 1996.06.27, including installation of concrete poles, tape grillage with the subsequent construction of the connections of columns with caps, and the caps are made of steel channels and each node connections are made in the form of anchor bolt attached to the end of the post eccentrically relative to the longitudinal axis of the Foundation with the subsequent establishment supports the second plate with hole for anchor bolt, the shape of the upper end of the post with the possibility of interaction between one plane of this plate with the said upper end of the post, and the other plane with shelf channel, and further accommodation under the nut anchor bolt l-shaped in cross-section the pressure plate, which is done with hole for anchor bolt on the large shelf, which include interacting part of the inner surface of the bent channel and the end of a small shelf with a support plate, the channel features over large quadrants of the plane of the end face of the pole with the center coinciding with the axis of the anchor bolt in the plan.

The drawback of such methods build the foundations are the high cost that affects the availability of housing construction with similar foundations for people with low income, for example the rural intelligentsia, and low performance.

This disadvantage is due to the fact that by itself, the method of construction of such foundations is complex and includes a large number of expensive installation work, as well as a large number of expensive components and materials. Also occurs in Siberia freezing at home due to cold bridges in the locations of the metal elements (plates).

The technical result is Vashego of the invention is to reduce the cost of installation and preparatory works, Foundation and housing in General, improving the reliability and performance of housing being built on this Foundation.

The technical result is achieved by the known method of Foundation construction, including the installation of underground pillars, strip Foundation and connections of pillars with grillage, according to the invention at the site of the proposed Foundation pre-select the soil with the formation of a "pan", the horizontal bottom of which is covered by sand filling, then bury the indentation to a certain depth posts and on the prepared sand filling in the horizontal plane of the bottom of the "trough" lay horizontal insulation screen by setting it on top of the buried pushing the poles into the pre-prepared holes in it buried under, set by pressing the pillars on which further set by nodes connect the tape grillage, then to the outer side of the recessed pillars attached to the intermediate wall, which, in turn, attach vertical insulation screen associated with the horizontal insulating screen, and in the trough formed on the two screens space stack waterproof castle, covering the top of a buried horizontal the second plateau insulation screen, who put sand preparation and in the future, paving, and on the inner side of the piles horizontal screen cover sand preparation, and the vertical wall insulation screen, attached to the outer intermediate wall rigidly connected with the sunken pillars, and the pillars bury the indentation using the excavator bucket, control pressed load deepens the pillars carried out using a dynamometer compression simultaneously with the process of pushing the post into the ground. As columns use tubular piles, mainly waste asbestotsementnyh pipes. Insulation screen are made of extruded polystyrene foam (extrol), and the intermediate wall use is made of cement-bonded particleboards, in addition, use tape grillage, made in the form of wooden beams, tightened the straps, and can also use ribbon Foundation is made in the form of concrete Rand-beams, the vertical wall insulation screen on the outside cover of insulating material, and as buried posts using plastic pipes, in addition, as the sunken pillars may use asbestos cement pipes or waste asbestos cement pipes, and waterproof castle, covering the top of uglublennoe horizontal plateau insulation screen are made peripatoi clay, moreover, the control pressed load on the pile is carried out using dynamometer compression simultaneously with the process of pushing the pile into the ground.

Between the features and achievable technical result is the following causal link.

In contrast to the process and prototype implementation of the claimed method of Foundation construction with thermal insulation screen, which are in the form of a vertical wall and connect with recessed horizontal plateau with holes through which spend sunken pillars, taking into account the fact that recessed horizontal plateau set on the sand preparation and cover from above, from the inside, sand preparation, and on the outer side of the waterproof cover lock, which cover the top of the sand preparation, which, in turn, covered with a blind area in the totality of symptoms, independent from one another, to enhance the reliability, operational quality built this way Foundation, as well as reduce its cost, because the presence of insulation screen allows you to reduce the depth of soil freezing and provides the opportunity not to drive piles in the form of recessed columns, but only to push them into the soil at a shallow depth, which greatly reduces the time vostede the Oia Foundation and consequently lower cost, moreover, the execution underground pillars in the form of asbestos cement pipes or waste asbestos cement pipes or plastic pipes also gives an additional reduction in the cost of foundations and eliminates cold bridges, which increases operational housing quality and reduces the cost of living there by reducing the depth of soil freezing. Installation in the construction of the Foundation intermediate walls of cement-bonded particleboards internal and external, to which is fixed a vertical wall insulation screen, provides a constant positive temperature ground floor, raising in aggregate of all features performance housing erected on the proposed way Foundation.
