Adjustable support for building structures.

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: flooring, paneling.

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 aguliera support for double floors, consisting of a bottom plate mounted on the base floor, and the top plate, interacting with elements of the flooring, and composite racks from the threaded rod and the tubular element. While the top plate is made of a square shape and is intended for use for different types of constructions floor without replacing the top plate (see DE 10116313, 07.11.2002).

However, in the known bearing top plate is made with a threaded rod and communicates with the tubular element of the lower plate, which is typical for high supports. For low supports, made of soft sheet metal material, it is necessary to provide structural elements, stiffening the structure. Support design in this source of information is not the subject of the invention.

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 Wallpaper is s (Cup) the Cup-shaped grooves of the wedge-shaped grooves, forming on the back side of the essentially flat support surface and a partial U-shaped radiating folds-ribs. At the corners of the square are the holes for the fastening elements (see EP 0980944, class E 04 F 15/024, 23.02.2000).

To the disadvantage of the known construction is that it is not intended for use for different types of constructions floor without replacing the top plate, in the center of the plate has a hole, which is significantly in size and reduces the strength of the plate, so in this part of the sheet metal 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 size of the plate is increased. This support is not intended for use with vertical load with a large eccentricity, as its top plate, as is clear from the drawing, is made smaller than the bottom. 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 smooth the surface of the floor durable and rigid design, the tion, having low cost and the possibility of using it for different designs of the floor.

The technical result achieved by the invention is to improve the sustainability of support and strength with a simultaneous expansion of its functions, reduction of material consumption, weight and ease of manufacture.

This result is achieved in that the 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 metal sheet material with a Central hole of a smaller diameter rod in place rigid connection with the screw rod and holes for fastening to the base, and a removable shock-absorbing and/or sound-absorbing lining with cut-outs and holes for secure attachment of structural elements, and with a Central hole, is equal to the hole of the lower plate, the upper support plate rigidly connected to the tubular element, the cavity which is inserted the free end of the threaded rod with nut, regulating and fixing the height of the upper support plate, and the surface of the bottom plate from the side adjacent to the base, provided with cross-shaped radiating from the Central the th hole edges with thickness, not exceeding the thickness of the sheet, and a length equal to half the diameter of the rod, and a radial grooves are V-shaped, radiating from the corners formed by the edges, while the top plate is made of the same material as the bottom, the surface around the tubular element facing the bottom plate, is made convex, smoothly passing respectively in a plane diagonally and cross located foothold with slots and holes for mounting and fastening of the floor slab and the Central hole of the upper plate facing the floor, surrounded by a circular recess in which the recess.

This technical result is also achieved by the fact that the center hole of the lower and upper bearing plates are made with a diameter of 2-3 times smaller diameters respectively of the rod and the tubular element.

Nut provided with a locking device made in the form of radial projections on the bottom 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 about the equipment, and/or damping and/or sound-insulating elements.

Excavation is made oval in cross section.

The upper and lower plates are made of sheet metal by stamping. Deepening located in an annular groove of V-shaped. 1 schematically depicts a bearing according to the invention, the view in the collection.

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 of the same size and from the same material as the lower support plate 1. In the center of the bottom plate 1 has a Central hole with a diameter less than the diameter mounted on it the threaded rod 3 is rigidly connected with the plate 1. The upper support plate 2 also has a Central hole having a diameter less than the diameter installed at the place of execution of the openings of the tubular element 4, rigidly connected with the upper plate 2, for example by welding. The Central openings of the plates 1, 2 are made with a diameter of 2-3 times smaller diameters of the rod 3 and the tubular element 4, respectively. In the cavity of the pipe is atogo element 4 is inserted the free end of the threaded rod 3, provided with a nut 5, regulating and fixing the height of the upper support plate 2. The top plate 2 from the side facing the floor, provided with a removable, shock-absorbing and/or sound-absorbing gasket (to hell. not shown), with cut-outs and holes for secure attachment of structural members made of elastic plastic. The bottom plate 1 from the side adjacent to the base, provided with cross-shaped radiating from a Central opening edges 6 with a thickness not exceeding the thickness of the sheet, and a length equal to half the diameter of the rod. On the same side of the plate 1 is made divergent from the angles of the ribs 6 of the V-shaped notches 7. The notches 7 are cross-sectional oval shape. The top plate 2 from the side facing the floor, made with an annular recess 8, surrounding the Central opening in the recess 8 are evenly spaced radial recesses 9, diverging at an angle of 60 degrees. The surface of the upper plate 2, facing to the bottom plate 1, made in the form of a parabolic hyperboloid, smoothly transitioning into a flat diagonally 10 and Phillips head 11 located foothold respectively with slots and holes for mounting to the floor elements. The angle between the tangent to the convex surface of the upper plate 2 and the horizontal axis is 5-20 degrees. the IKE 5 provided with a locking device (on the devil. not shown)made in the form of radial projections on the bottom surface of the nut in contact with the grooves located at the free end wall of the tubular element 4. Holes for fasteners of the upper plate 2 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. The upper 2 and lower 1 plate made of sheet metal by stamping, the lower plate 1 is made at the corners of the square holes 12 for mounting the elements of the Recesses 9, located in the annular recess 8, is made V-shaped.

The operation of the device

Support in the process of its operation is subjected to alternating axial loads, including temporary compression. As local thinning always concentrate on yourself a shot, and bearing according to the invention is made of a thin soft sheet metal, then it should not have sharp transitions (pairing). In known constructions the Central openings in the plates was performed corresponding to the dimensions of the threaded rod for installation and tubular element, which was part of the funnel-shaped surface of the upper plate. Therefore, it was proposed wedge-shaped ribs, nests with a double layer of metal, as visheukazannim nearest equivalent.

In the support according to the invention, made of soft metal, for example mild steel first elongation 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. Therefore, you increase the rigidity of the two supporting plates. Therefore, the surface of the upper plate 2 is carried out in the form of a parabolic hyperboloid. However, such performance is not enough when using the top plate 2 for different designs of the floor without replacement, as it has to increase its area, and the maximum can be increased only up to the dimensions of the bottom plate. The top plate is provided by an annular groove 8 around the hole with radial grooves 9 (ribs) in it that tightens the design, since the top plate 2 has a slot which can be up to half of its length. Preemptive execution of a paraboloid with a flat surface. The upper 2 and lower 1 plate by tightening the Central hole, less 2-3 times rod 3 and the tubular element 4. However, such performance is not enough to obtain the technical result, resulting in the design of reinforced cross astashkina from the Central hole edges 6 of rigidity, because this place is busy, and additionally the slots 7 of the V-shaped form, that is important in this design, to defuse tensions preemptive execution is the execution of fill of oval form. This form is optimal, and therefore the reference flat surface of the bottom plate 1 becomes larger, which increases the stability of the support. During operation confirmed the reliability of a support according to the invention, its durability, stability, and support easy to manufacture.
