The invention relates to the construction, in particular for flooring 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.

In the known construction of raised floors installed with supports at some distance from the power structures overlap of the building, i.e. from the ground floor. This floor creates the underground space is used for laying electrical and other utilities, provides convenient access to them during operation. Raised floor includes many poles, evenly distributed on the surface of the subfloor and related structural elements forming the surface: the flooring panels. Preferably, support was provided by the location of the floor at the required level, flat and smooth surface, durability, and rigidity. As impossible fabrication and installation of floors of buildings with high precision, to address the above requirements perform support adjustable in height.

Known adjustable support for double floors, consisting of a bottom who lastine, installed on the ground floor, and the top plate, interacting with elements of the flooring, and composite racks from the threaded rod and the tubular element (DE 4132989, class E 04 F 15/024, 1993). Top plate, in a decision made in the form of an open top of the funnel, which has a shock-absorbing element. The extra element overlying the cavity is difficult to manufacture a funnel-shaped top plate, increases the work on the device adjustable foot, increases the flow of material.

The closest analogue of the invention is an adjustable support, mainly for floor construction, including made of sheet metal bottom plate in the form of a square, is rigidly connected with a threaded rod installed in the Central (bowl-shaped) recess, and an upper plate connected to the tubular element into the cavity with the possibility of axial movement of the inserted free end of the threaded rod with nut. To increase the mechanical rigidity of the bearing in the upper part of the shroud (Cup) the Cup-shaped grooves of the wedge-shaped recesses that form on the reverse side essentially flat support surface, and a partial U-shaped radiating folds-ribs. At the corners quadraticresponse holes for fasteners (see EP 0980944, class E 04 F 15/024, 23.02.2000).

To the disadvantage of the known construction is that the metal sheet forms at the apex of each wedge-shaped recesses two layers, which leads to the increase of material consumption, the weighting of the construction. In addition, when increasing the mechanical rigidity of the stability of the bearing is reduced due to failure flat surface for contact with the ground, therefore, to eliminate this drawback, the dimensions of the plate increases, and holes for fasteners installed at a considerable distance and have heavy loads.

The task on which the invention is directed, is to create an adjustable support for the location of the flooring at the required level from the base and provides a smooth surface of the floor, the strength and rigidity of construction, low cost and simplicity.

The technical result achieved by the invention is to improve the sustainability of support and strength while reducing material consumption, weight and ease of manufacture.

This result is achieved in that in an adjustable support for the building industry, mainly for flooring with design elements that are installed at a predetermined height from the substrate, containing the lower support plate in the form of a square of soft IU alicebraga sheet material with a Central opening to accommodate the threaded rod and the rigid coupling of the plate, equipped with a removable shock-absorbing and/or sound-absorbing elastic gasket having openings and a platform for secure attachment thereto of structural elements, the upper support plate with a Central hole for rigid connection to her at the place of execution of the hole with the tubular element, the cavity of which is inserted the free end of the threaded rod with nut, regulating and fixing the height of the upper support plate, with the Central hole of the bottom plate has a slot to insert a rod and surrounded by a circular recess, not exceeding the thickness of the sheet, and the hole of the upper plate of the frame, from the recesses and flanging depart radial facing each other convex surfaces dredging, excavation and deepening have an oval contour of the cross section, and the places of their mates oval contour in longitudinal section or wavy, top plate made of the same material as the bottom, its form and shape of the strip congruent form the bottom plate, the side length of the square last less than the length of the lower support plate, and holes for mounting the elements of the lower support plate and holes for fixing the strip to the upper support plate, made in the notches on the diagonal squares are aligned.

Specified achiev that is achieved and the that support is made from four to eight notches, that the nut is provided with a locking device made in the form of radial projections on the upper surface of the nut in contact with the grooves located at the free end wall of the tubular element. The threaded rod and the tubular element rigidly connected with the base plate by welding.

Holes for fasteners of the upper plate can be designed for attachment thereto of structural elements, floor-type beams or flooring, and/or equipment and/or damping and/or sound-insulating elements. Annular recess of the lower support plate and the grooves of the two plates can be filled with adhesive material.

The tubular element is filled with filler.

The upper and lower plates are made of sheet metal by stamping.

The top plate crosswise spaced notches, bounded on two sides by slots represent a platform for placement of the elements of the floor structure.

Used head bolts for mounting in a recess corresponding to the shape of the recess, thread or screws.

On the upper side of the gaskets are made of a rib, which the spacer plate holders flooring.

The corners of the squares of the plates and the gaskets are made with a slant.

The side length of the square top p the plates and gaskets is 0.65-0.8 length of the lower support plate.

Excavation is not more than 20% of the area of each square, mostly 10-20%.

This technical result in the known structures has been achieved in the manufacture of bearings of the soft metal sheet material. The difficulty lies in the fact that, as follows from the test samples of soft metal, for example mild steel, at the beginning of the lengthening grow proportionally to the load, then, as the loading appears the yield strength. Resulting in the sample appear inside in all directions subtle grooves on sloped areas. Destroyed the sample has a view or two cones, from which separated the sides, or two pyramids, closed its vertices. Therefore, you increase the rigidity of the two supporting plates. The top, as follows from the above analogy, tightening performing with funnel-shaped cavity, which increases the material cost and complicates the production, since it is necessary to also strip overlying the funnel.

In the known construction, is selected as the closest analogue of this problem to some extent solved for the lower support plate. However, the presence of wedge-shaped ribs causes stress concentration and the emergence of dangerous cracks, and therefore, to avoid adverse events, increase the size of the place, the ins or its thickness.

In addition, the mounting holes in the plate are arranged at the corners of the square, which also increases the flow of material and the weighting of the structure.

Figure 6 - section II-II in figure 2.

Adjustable support comprises a lower base plate 1 made of a soft metal sheet material in the form of a square, the upper base plate 2, made in the form of a square and of the same material as the lower support plate 1. Both plates each have a Central hole: lower for rigid connection, for example, by welding with the screw rod 3, which is placed in the hole, and the upper for rigid connection to her at the place of execution of the hole with the tubular element 4, the free end of which is inserted in the rod 3, the latter being provided with a nut 5, regulating and fixing the height of the upper support plate 2. The Central hole of the bottom plate 1 has a socket (the drawing is not marked for installation of terminal 3 and surrounded by a circular recess 6, with the branching grooves 7. The annular recess 6 does not exceed the thickness of the square and is more about the a priori surface. The Central hole of the upper plate 2 is flared and extending from the latter by the grooves 8. The notches 7, 8 with their convex surfaces facing each other and are located at number eight: the diagonals and the midpoints of the sides of the square. The notches 7 and 8 and the recess 6 (see figure 5) have an oval contour of the cross section (ravnovesnost constant distance between the two parallel tangent), and the places of their mates oval contour in longitudinal section or wavy. Support also includes removable elastic strip 9, which is shock-absorbing and/or sound-absorbing, made in the form of a square equal to the square of the upper plate 2, and at the location of reference sites 10 with rectangular cutouts for mounting components. The side length of the square top plate 2 and the strip 9 is less than the length of the square side of the lower plate 1 and is 0.65 to 0.8. With the smaller sizes of these elements is lost stability support, and at large design weights and increased material consumption. On the diagonal grooves 7 of the plate 1 with holes 12 for mounting the elements, as in plate 2 - hole 13 for fastening strip 9. Holes 12, 13 are made on the same vertical axis. The spacer 9 is made of a polymeric material with a Central hole, is equal to the hole of the upper square is tiny 2, and has projections (not shown) on the surface facing the plate 2 and on the opposite surface of the locking ribs 14 on the midpoints of the sides of the square. All the squares are made with bevels at an angle of 45 degrees. Nut 5 is provided with a locking device made in the form of radial projections on the upper surface of the nut in contact with the grooves located at the free end wall of the tubular element.

Holes 13 for mounting the top plate can be designed for attachment thereto of structural elements, floor-type beams or flooring, and/or equipment and/or damping and/or sound-insulating elements.

Annular recess of the lower support plate and the concave surface of the radial ribs of the two plates can be filled with adhesive material. The tubular element 4 is filled with filler. The upper and lower plates are made of sheet metal by stamping. The top plate crosswise spaced notches, bounded on two sides by slits, are supporting pad 10 to accommodate elements of the floor structure.

In the support used head bolts for mounting in the recess 7 corresponding to the shape of the recess, thread or screws.

The notches 7, 8 is not more than 20% of the area of each square.

The operation of the device.

Supports the process of its operation is subjected to alternating axial loads, including temporal compression. As local thinning always concentrate on yourself blow, and support, according to the invention, made of a thin soft sheet metal, then it should not have sharp transitions (pairing)with the above form of execution is predominant. However, such performance is not enough to obtain the technical result, resulting in the design of reinforced ribs, including the diagonals of the square. Holes 12, 13 for fastening elements also weaken the structure, so they perform in the ribs. The orifices 12, 13 are aligned, thereby reducing the impact of stress on the fasteners of the lower plate 1, since the sizes of the top plate 2 in order to save material and lack of production necessary, perform a smaller area. In addition, the location of the holes on the smaller dimensions of the plate causes its resistance when set to not smooth the surface of the base, as you can install it on a flat plot.

This result is achieved by all the features set forth in the claims.

Experimental work has shown the reliability of support, increasing its service life.
