The invention relates to the field of construction, in particular to designs boards for raised floors with high load capacity, intended primarily for offices with heavy equipment.

Known plate raised floor, including coronopathy element, made of metal, having a bottom and side walls with the first edges bent outward, placed in Korobkova element inner supporting layer, and the flat element of the cover, also made of metal and having a second edge, which is bent twice around the first edges forming a seam connection in the upper zone of the side walls of the plate. (WO 99/18305, class E 04 F 15/024, 1999).

A disadvantage of the known solutions is the low reliability of the joint metal plate parts due to the fact that under the action of concentrated loads on the plate from furniture, heavy equipment, etc. the highest stresses occur in the upper area of the end faces of the plate, i.e. in the area of the seam compound, which may lead to its destruction.

The closest analogue to the claimed invention is a floor plate, including lucabrasi element, made of metal, forming the base plate and side walls with curved inside plate edges parallel to its base, placed in dotcooperation is lemente inner supporting layer made of pressed particle Board material, covered metal sheet (FR 2624538, class E 04 F 15/024, 1989).

In a known solution for ensuring the continuity of the upper surface of the slabs for flooring outer decorative layer of carpet, ceramic tiles, bent edges of the side walls lodkoobraznuyu element placed in the slots of the frame element mounted on the upper edge of the inner supporting layer, which complicates the design of the plate and does not provide a strong connection metal part of the inner layer.

The technical task of the present invention is to reduce labor costs in the manufacture of the plate, increasing its rigidity due to the joint work of the internal base layer of wood material with a surrounding metal shell.

This problem is solved due to the fact that the floor plate, including lucabrasi element, made of metal, forming the base plate and side walls with curved inside plate edges parallel to its base, placed in dotcooperation element inner supporting layer made of pressed particle Board material, covered by a metal sheet, the perimeter of the inner supporting layer having a variable density along the height of the notch and along the perimeter of the sheet metal with the lower side of the protrusion in contact with in the capacious, when this bent edge of the side walls are connected with the metal sheet in the zone of contact of the tabs with the slots, and their outer surfaces are in the same plane with the outer surface of the sheet metal, which is connected to the inner support layer is pressed through blind holes and/or glue.

Preferably, the width of the notches of the inner supporting layer of the slab does not exceed 20 mm

Preferably folded edges of the side walls of the plates are connected with the metal sheet through the point of indentation, the distance between the points of indentation is 30-50 mm

Preferably the inner supporting layer plate made in the form of particle Board, the end faces of which as of the end faces lodkoobraznuyu element, oblique to the base inside the panel at an angle equal to 5-8°mainly 6°

Preferably sheet metal plate made of galvanized steel with a thickness of 0.4-1.0 mm, mainly 0,4-0,5 mm

Preferably the inner supporting layer plate has at least two layers with a high density of more than 800 kg/cm3and tensile strength in the range 0,785-1,177 MPa located in the zone of contact with the metal parts of the plate.

Preferably the thickness is from 10 to 40 mm, mostly 38 mm, and in terms of size 600×60 mm

The invention is illustrated by drawings, which shows:

figure 1 - section of the slab;

figure 2 - a view A-a in figure 1;

figure 3 is a fragment of a slab in the long term (excluding sheet metal).

Floor plate consists of lodkoobraznuyu element 1, the bottom of which forms a base plate, and its end edges, the side walls 2 plates having bent inside of the slab edges 3, parallel to its base.

Inside lodkoobraznuyu item posted by the inner supporting layer 4 made of pressed particle Board material, covered by a metal sheet 5, which is connected with the inner layer of glue using, for example, vinyl glue, and pressed through blind holes, and pressed the edges of the holes are in the particle material.

On the perimeter of the inner supporting layer of particle material made of the recess 6, and the perimeter of sheet metal with the lower side of the projections 8 in contact with the grooves and having a cross section identical with them the form.

Formed on the outer side of the metal sheet 5 due to the protrusion, the recess is designed to accommodate the bent edges 3.

To create a flat horizontal upper surface of a plate, which in the future will be laid carpet or other decorative covering, the outer surface of the bent the edges should be located in the same plane with the outer surface of the metal sheet. For this excavation depth should be equal to the total thickness of the sheet metal and the thickness of the bent edge, and the width not less than the width of the bent edge.

Bent edges connected with a metal sheet through a point indentation 7, the distance between the points of indentation is 30-50 mm

Lucabrasi element and the metal sheet is made of galvanized steel with a thickness of 0.4-1.0 mm, mainly 0,4-0,5 mm

The inner supporting layer has at least two layers with a high density of more than 800 kg/cm3and tensile strength in the range 0,785-1,177 MPa located in the zone of contact with the metal parts of the plate.

In the case of slabs flooring for floors, perceiving heavy loads, for example for floors under heavy equipment, the number of reinforcing layers can be increased, i.e. in addition to these surface layers of high density wood particle material can be one or more intermediate layers placed interleaved with layers of lower density.

To install the plates on the ground floor on the supporting plate height-adjustable racks with protruding vertical ribs for fixing panels, the end faces of the bearing layer is carried out of the sloped panel to its base at an angle 5-8°mostly 6° (the goal between the inclined face of the base layer and vertical plane).

The process of manufacturing plates is as follows.

First make particleboard. To do this, in a reactor with a reflux condenser download formalin solution and set pH 8.0-8.4 and. Then download the urea. At temperatures up to 60°the mixture was incubated, after which it enter the modifying additive. After the introduction of modifying additives, extracts of the reaction mixture to raise the temperature. While achieving Miscibility with water 1:1.5-2 mixture is cooled to 60-65°With, then load the second portion of urea. The mixture is cooled to 30°C. Then carry out the pressing plates with decreasing temperature up to 20-30°C.

In enterprises that have a simple equipment, including lines with the use of contact adhesives and roller presses, as an internal base layer can be used in the finished particle Board that is cut to the specified dimensions.

On all sides of the inner bearing layer applied adhesive selected from commercially available adhesive for bonding wood material with metal.

Lucabrasi element can be pre-fabricated by cutting a flat metal sheet having a Central rectangular portion, an area equal the area of the base plate, and extending from each side edge of the strip widths of the th, exceeding the height of the end faces of the inner bearing layer is not more than 20 mm for the formation of the flange. Due to bend upward edge strips form a metal coating in the form of a tray that is placed particleboard made it to the perimeter of the excavation.

Another way of facing particle Board is that it is laid on a rectangular cut sheet metal, and then marginal bands bend up and over her butt.

On the upper surface of particle Board laid flat metal sheet with the tabs within the hollow particle Board, and connect to it through the glue and pressed blind holes. Then bend bent edge lodkoobraznuyu item by placing them in the deepening of sheet metal and connected to it through the point of extrusion.

Proposed floor plate, enclosed on all sides by a metal casing and is firmly connected with it, is able to withstand a large load range, so that the allowable distance between the supports may also be administered in a wide range.
