The invention relates to the field of construction, in particular to the structures of prefabricated panels floors that form in areas of underground space for laying electrical communication and/or ventilation by installing panels on adjustable supports.

Known adjustable support team of the floor structure containing a rod rigidly connected with the support plate, and a housing made in the form of a sleeve having one edge of the mounting flange, and the other with a cylindrical flange mounted with the possibility of axial movement and fixation on the rod (EP 0980944 A1, class E 04 P 15/024, 23.02.2000).

Side liner-known support has the shape of a cylindrical surface, which made the reinforcing elements in the form of ribs, pressed by covering the core part of the liner.

During operation of the floor bearing is experiencing significant alternating axial load lateral component.

When calculating the strength of the structural elements of the sexes type of liners, which is essentially a thin-walled cylindrical tube with a significant value of the ratio of length and diameter, whereas the possibility of losing sleeve resistance due to bending compression under axial loading.

The disadvantages of the known support is significant that the woman of the wall due to the need to ensure longitudinal stability of the liner, and the associated increased consumption of material and the weighting of the construction. In addition, due to the developed flange compared to the relatively small diameter of the sleeve, under the action of the lateral component of the alternating load, there is a danger of deformation of the flange, which when critical loads can occur even before the liner will lose longitudinal stability.

Known adjustable support team of the floor structure containing a rod rigidly connected with the support plate, and a housing made in the form of a sleeve having one edge of the mounting flange, and the other with a cylindrical flange mounted with the possibility of axial movement and fixation on the rod (E 4132989, class E 04 P 15/024, 08.04.1993).

Side liner-known support has the shape of a conical surface on which the elements of its gain in the form of longitudinal and facing the flange extruded ribs.

Adjustable support this design precast floor is the closest analogue of the claimed device.

In this device partially addressed the shortcomings of previous similar due to the execution of a sleeve with a tapered side surface can be reduced wall thickness, and connecting the side Gil is s with flange stiffeners increase its strength. Despite a slight increase in the transverse dimensions due to the formation of the conical part of the body, reducing the wall thickness reduces the material consumption in General. However, this design of the liner does not provide a significant reduction in the thickness of its walls. When reducing the wall thickness to obtain the required strength of the case requires the reinforcing elements of the side of the sleeve and flange, which complicates the design and manufacturing technology of housing supports.

The problem to which the invention is directed, is the elimination of the disadvantages of known construction support and provide the necessary strength characteristics while reducing material consumption, simplifying the design and fabrication hull supports.

This technical result and other advantages are achieved due to the fact that the adjustable support team of the panels of the floor structure containing a rod rigidly connected with the support plate, and a housing made in the form of a sleeve having one edge of the mounting flange, and the other with a cylindrical flange mounted with the possibility of axial movement and fixation on the rod, a lateral side of the sleeve, at least half of its length from one to the other flange has a shape of a curved surface formed by rotating the line segment Deuteronomy is the second order around an axis of a support.

This allows you to enhance the strength characteristics, and in particular longitudinal stability of the hull supports, characterized in operation alternating axial loads, when the support body is experiencing complex loading, including temporary compression. In addition, it becomes possible to simplify the design and fabrication hull due to the exclusion of the reinforcing elements of the side of the sleeve.

It is preferable to perform the side of the sleeve throughout its length from one to another flange in the form of a curved surface formed by rotating the line segment of the second order around an axis of a support.

In addition, the ratio of the largest diameter side of the sleeve to the diameter of the support flange is 0.3 to 0.6. This provides ravnopravnosti flange and the side of the liner under the current load. When the specified diameter ratio of the load exceeds the maximum flange is deformed, and the lateral side loses longitudinal stability almost simultaneously.

The curvilinear side surface of the cartridge case can be made convex or concave.

In addition, the tangent to the line segment that forms a curved surface shape of the side of the sleeve, the end point of this segment directed toward the support of f is the like, can be parallel to the axis or fulcrum, is it at an angle.

Preferably, the tangent to the line segment that forms a curved surface shape of the side of the sleeve, the end point of this segment, facing to the support flange was located to the axis of the support at an acute angle, the magnitude of which increases from the aforementioned point of the segment to the other endpoint, facing the cylindrical flange.

To simplify the manufacture of the line segment of the second order can be represented as an arc of a circle.

Lateral side of the sleeve can have a plot of a curved surface formed by rotating the line segment of the second order, and mated with him in the flange area of the cylindrical or conical surface.

In addition, the lateral side of the sleeve can have a plot of a curved surface formed by rotating the line segment of the second order, and mated with him of the support and/or cylindrical flange area of the conical surface.

Lateral side of the sleeve can have lots of mates with flanges, which have the shape of a curved surface formed by rotating the line segment of the second order around an axis of support. The presence of areas pairing improves the strength characteristics of housing supports.

To simplify design and cut, forming a shape of a curved surface mates, is an arc of a circle that is inherent in the structures obtained, for example, by casting.

The ratio of the radius of the circular arc forming section mates, and the radius of the circular arc forming the side surface of the liner is between 0.01 and 0.1, the housing may be made of sheet metal by stamping.

In addition, the mounting flange has a support point for the placement of the ends of the U-shaped cross-sectional profile, load-bearing floor panel.

Each support platform is made to open on the edge of the flange grooves for passage of the vertical wall profiles and is located between the grooves element of strengthening flange, made in the form of open-ended at the edge of the flange and parallel to the grooves of the extruded trough with a flat bottom, which is opposite the open edge of the ditch, made a hole for securing the end of the profile.

The depth of the trench is 0.5-1.5 thickness of the flange.

Most high strength characteristics of the hull supports are provided when the ratio of the diameter of the rod to the greatest diameter side of the sleeve when the thickness of the wall of 2-5 mm is 0.4 to 0.6, and the ratio of the diameter of the rod to the length of the cylindrical flange and the length of the side of the sleeve, measured on the si support, is 0.2-1 and 0.6 to 0.9.

This provides ravnopravnosti flange 6 and bokoviceva sleeve 4 under the current load. At the specified ratio of the diameters D2 and D under the action of the load exceeds the maximum flange is deformed, and the lateral side loses longitudinal stability almost simultaneously.

The curvilinear side surface of the cartridge case can be made convex or concave.
