The invention relates to the construction, specifically to the decking floors, tiles, walls and ceilings, and can be used in the construction of floors, paneling, installed at a given level relative to their base, to improve the quality, reduce the complexity and cost of manufacture, and can also be used in the construction of the adjustable beacon for plastering.

Art

Known floor that is installed at a specified level relative to the base with adjustable feet. Adjustable support made of fastener-supporting element in the form of a hollow rack with an external thread, is screwed in a threaded hole in the floor joists, with hollow strut is closed at one end, the end attached to the subfloor by a clamp, and in the upper part of the rack can be provided with a bushing with a flange attached to the lag of the floor from the side adjacent to the base. (see RF patent 2157877, E 04 F 15/00, 2000)

The disadvantage of this design adjustable supports so the drop from the specified forms: variation of the horizontal, vertical and twist in cross section. This leads to a distortion flatness of the floor. In addition, the ground floor also has errors in the geometry of the surface, which leads to point-support rack on the ground floor, for shifting the fulcrum of the rack relative to its axis and, consequently, to the creation of additional internal stresses in the rack when it's fixed retainer. Moreover, the presence of screw holes of considerable size in the lag reduces its strength characteristics. All this leads to a deterioration in the quality of the floor, reducing its durability.

In this case the rod is installed on the elastic element having a recess for the head of the rod. The lower surface of the elastic element is made in the form of a cone, which ensures the alignment of the rod to support the(see the Japan patent 2934958, class E 04 F 15/00, 1998)

The disadvantage of this design is that the support has a base point contact, resulting in increased stresses in the cylinder, the elastic element and the presence of large deformations of the floor under load, reducing the durability of the bearing. In addition, the need to make holes for the supporting element in a floor construction reduces its strength characteristics. All this affects the quality of the floor surface.

The invention

The objective of the invention is to develop such a design adjustable support, which would ensure the installation of the building structure at a given distance from the substrate with high precision, would rule out deviations from the level of its deteriorating the surface quality. In addition, the design should provide for compensation of deviations in the geometry of the elements of the building structure, for example, lag floor during installation and during operation. Moreover, the design of the supports must make a minimum weakening of the building structure, to ensure reliability and durability in operation.

According to the invention this object is achieved in that in the handle is at a predetermined height from the substrate, contains supporting element made in the form attached to the base of the rod with external thread, and a support platform that interacts with the threaded rod, the rod is made with a spherical outer surface at the lower end and mounted in the thrust bearing mounted on the base.
