The invention relates to the field of construction, in particular to the structures of the panels of the raised floor with anti-static properties and intended for offices equipped with computers.

Known the raised floor panel including a first metallic element in the form of boxes with flat rectangular part having a bent along its perimeter edge, and a second metallic element, similar to the first form. The first box is placed in the second, with the formation of the space to be filled reinforcing element, the side edges of each face panel mechanically interact (FR 2683242, class E 04 F 15/024, 1993).

A disadvantage of the known solutions is the high intensity of the panel due to the presence at her side the faces of the two layers of metal.

The closest analogue to the claimed invention is a raised floor panel comprising a slab of wood material, enclosed on all sides by a metal sheath, consisting of upper and lower ducts having a rectangular portion forming upper and lower horizontal faces of the panel and bent around the perimeter of the rectangular portion of the side edges of the covering end faces of the plate. When this bent side edges of the top boxes close half height

end-face plates, and other floors is well close the bent edge of the lower box. Thus, the ends of the side edges of the upper and lower boxes are located against each other (DE 3843589, class E 04 F 15/024, 1990).

Due to the tolerances that exist when cutting metal sheets, to make the joint of adjacent edges on the end faces of the famous panel with no gaps is extremely difficult.

The technical task of the present invention is to improve the reliability of connection of metallic parts of the panels, increasing its integrity, without the use of additional fasteners.

This problem is solved due to the fact that in the raised floor panels, comprising a carrier plate made of wood material, enclosed on all sides by a metal sheath, which is pre-moulded into the shape of two boxes - the top and bottom, each of which has a rectangular portion forming respectively the upper and lower horizontal faces of the panel and bent along the perimeter of the rectangular side edges, closing the half height of the end face plate, the area of the rectangular part of the upper boxes exceeds the area of the rectangular portion of the lower duct by an amount equal to 4-5 δwhere δ - the thickness of the upper boxes and bent side edges of the upper and lower boxes of equal height, with the end portion adjacent the lateral edges on each end side of the slab is pressed lap.

End of gr is neither slabs of wood material of the sloped panel at an angle, equal 5-8° mostly 6°.

The side edges of the boxes are made at an angle coinciding with the angle of contact with the end faces of the plate.

As the plate using wood particle Board.

Metal shell panel can be made of galvanized steel with a thickness of 0.4-1.0 mm, mainly of 0.4-0.5 mm particleboard has a variable density altitude, while layers with a high density of more than 800 kg/cm3and tensile strength in the range 0,785-1,177 MPa is located in the contact zone with a rectangular parts boxes.

Panel thickness ranges from 10 to 40 mm, mostly 38 mm, and in terms of size 600×600 mm

The invention is illustrated by drawings, which shows:

figure 1 - installation of raised floor panels on adjustable legs;

figure 2 - section of the panel.

The panel raised floor designed for installation on adjustable feet above the ground floor, consists of chipboard 1, surrounded on all sides by a metallic shell, which is pre-moulded into the shape of two boxes 2 and 3, the open portions facing each other and located at the top and bottom plates.

As the metal shell using galvanized steel with a thickness of 0.4-1 mm, mostly 0,4-0,5 mm

Particleboard has a variable density h is those i.e. includes at least two horizontal layer of high density of more than 800 kg/cm3and tensile strength in the range 0,785-1,177 MPa. These layers are located in the zones of the plate adjacent to the inner surface of the metal shell.

In the case of flooring panels for floors, perceiving a large load, for example, floors under equipment or in warehouses, the amount of hardening

layers can be increased, i.e. in addition to these surface layers of high density can be one or more intermediate layers placed interleaved with layers of lower density.

End face chipboard, which essentially form the end wall panels, beveled to the base inside the panel at an angle equal to 5-8° mostly 6° with the possibility of contact of adjacent panels in the upper portion thereof. Inclined end wall panels provide their installation on a plate adjustable racks that have the speakers up ribs for fixing the position of the floor panel.

The bottom 2 and top 3 boxes made of sheet metal by bending up the side edges placed on the perimeter of the rectangular portion of the sheet between cut corners.

The area of the rectangular part of the upper boxes exceeds the area of the rectangular part of the lower to the Rob by the value equal 4-5 δwhere δ -the thickness of the upper boxes. Bent edge both boxes of equal height and the height of each of them is half the height of the end face plate.

The thickness is from 10 to 40 mm, mostly 38 mm, and in terms of size 600×600 mm

The manufacture of the panel is as follows.

On the surface of the chipboard is applied polymer adhesive, for example, adhesive vinyl and placed it in the bottom box. Then the upper box set on the bottom and using a roller press bend the corners of the top of the box and pressed overlap the side edges of the bottom box.

The technical result of the invention is to increase the amount of the compensation for inaccuracies of manufacture metal boxes, the increase in the rigidity of the end faces of the panel and increase

the bearing capacity of the plate, which allows to increase its size up to 600×600 mm, install the adjustable feet at a greater distance from each other, and therefore significantly reduce the cost of the floor.
