Known all-metal panels for raised floors, having ventilation grilles on top, for example: http://zelberg.ru/metall.html

The panels are made of square profiles that form a frame along the perimeter of the panel, connecting the panels with support lintels from below. All this one-piece structure is covered with a flat top plate in the form of a ventilation grill with through holes.

Although this panel has ventilation and drainage properties, it is technically complex in design and has a lot of weight. In addition, for the manufacture of such a panel, a large metal consumption is used and this panel, despite the presence of drain holes, cannot be used for laying a roll of green lawn based on natural grass and soil, since part of the soil and water will drain through the holes onto the support lintels and lead to their corrosion.

The closest analogue is a SPLITTABLE FALSE FLOOR WITH PERFORATION FOR HIGHER LOADS (published on 11/29/2017) see https://www.lindner-group.com/fileadmin/user_upload/intranet/dienste/marketing/techn_broschueren/technreinraum_r en.pdf on pages 35-44

The panels are made of U-shaped profiles that form a frame around the perimeter of the panel, connecting the bottom panels of the support lintels in the form of a grid. All this one-piece structure is covered with a flat top plate in the form of a ventilation grill with through holes.

This panel has ventilation and drainage properties.

The technical problem of the prototype is that the panel is technically complex in construction and has a lot of weight. In addition, a large metal consumption is used for the manufacture of such a panel.

This panel, in spite of the presence of drainage holes, cannot be used for laying a rolled green lawn based on natural grass and soil, since some of the soil and water will flow through the holes onto the support lintels and lead to their corrosion.

The task of the utility model is to eliminate the shortcomings of the prototype and other known solutions.

The technical result is to provide the panel with ventilation and drainage properties with simultaneous design simplicity, low weight, and lower metal consumption. In addition, the technical result is the ability to use the panel for laying both a roll of green lawn based on natural lawn grass and soil, and an artificial roll lawn.

The specified technical result is achieved due to the fact that the declared panel for a raised floor, made in the form of a metal structure with a thrust frame around the perimeter, having through holes in the upper flat plate, characterized in that the thrust frame is formed from the upper flat plate by bending its edges along the perimeter , in places of bends from opposite sides, coaxial through holes are made.

Preferably, at the point where a corner is formed from the folded adjacent edges of the plate, one of the folded edges has a corner cut.

Preferably, the panel is made of stainless steel or galvanized steel.

Implementation of the utility model

The panel for the raised floor is made in the form of a metal structure with a thrust frame around the perimeter, having through holes 4 in the upper flat plate 1 (see figure 1, figure 2).

What is new is that the abutment frame is formed from the upper flat plate 1 by bending its edges 2 around the perimeter. In addition, in the places of bends 2 from opposite sides, coaxial through holes 3 are made.

Coaxial through holes 3 serve both for the purpose of additional drain holes and for the purpose of using them to connect the panels 6 to each other, for example, with bolts or clamps, in order to increase their strength and reduce their mobility. For this reason, the alignment of the holes 3 is important so that they are strictly opposite each other in panels of the same type.

A roll of green carpet 9 is placed on top of the flat plates 1 of panels 6 installed on a given area.

Due to the presence of through holes 4 in the upper flat plate 1, ventilation and drainage properties are provided for the panel.

Thus, in Fig. 4, it can be seen that the drainage of water is provided through the holes 4 and the slots between the panels 6. The water can then drain through the drainage drain 10 located at the base of the floor.

In addition to these properties, the utility model allows, due to the exclusion of the support frame from the profiles and the elimination of the lintels, only due to the bends of the edges 2 of the upper flat plate 1, to create sufficient stiffening ribs replacing the support frame and, thereby, is characterized by low weight (in comparison with known analogs ), as well as lower metal consumption.

In addition, due to the exclusion of frame profiles around the perimeter, as well as the elimination of lintels, it is possible to use the panel not only for laying artificial turf, but also for laying a roll of green lawn based on natural turf and soil. This possibility is realized due to the fact that the waste water does not stagnate in the elements of the panel 6, but flows down and in the panel 6 there are no elements that can accumulate soil particles and moisture, creating rotting and corrosion.

Coaxial through holes 3 when using a roll green lawn based on natural grass and soil serve for the purpose of additional drain holes. So, when soil particles, falling into the gaps between the panels, clog them so much that the water flow through the gaps is reduced, the through holes 3 provide the possibility of additional drainage. For this reason, the alignment of the holes 3 is important, so that their position is strictly opposite to each other in panels of the same type, giving a common through drain hole.

In the place where the corner is formed from the bent adjacent edges 2 of the plate 1, one of the bent edges 2 can have an angular cut 5. Through the slots in the cuts 5, metal plates can be laid in parallel laying, which provide not only reinforcement of the strength of the panel 6, which rests on an adjustable bearing support 7, but also reduces the mobility of the panels 6, which are installed on the bearing supports (see Fig. 3) with an emphasis on the protrusions 8 located on the upper parts of the supports 7. These cuts 5 are not necessary, like the parallel laying of metal plates, but are preferable in those cases where the coaxial through holes 3 are used as drain holes and are not used for bolting purposes.

So, if in the formed carpet on the panels 6 on top of the raised floor it is necessary in the right place to get access to repair or replace the bearing support 7 of the raised floor, a certain sector of the green lawn is opened (see Fig. 5), then using a device such as a grip with a handle, the latter inserted into the slots between the panels (see figure 6). By pulling the handle, the edges of the grip pull together the edges of the panel and clamp them so that the panel can be pulled out (see Fig. 7). Then get access (see Fig. 8) to the desired sector for repair or replacement of the bearing support 7 of the raised floor or for another purpose (laying of communications, floor heating systems).

For laying a roll of green lawn based on natural lawn grass and soil, the panel is preferably made of stainless or galvanized steel in order to exclude corrosion of the panel itself and the effect of the acidic environment of soil and water.

The declared utility model thus makes it possible to ensure the laying of both a rolling green lawn based on natural lawn grass and soil, and an artificial rolling lawn. The location at the base of the floor under the panels 6 of various types of heating systems allows the use of such panels on flat roofs of buildings and equip living green lawns there, which can be kept at any time of the year, including in winter (if it is possible from above to provide a glass shelter - a greenhouse , and artificial turf turf if external glass shelter cannot be provided).
