PANEL WITH POSSIBILITY OF CONNECTION WITH SIMILAR PANELS FOR FORMATION OF COATING Russian patent published in 2020 - IPC E04F15/02 E04C2/30 

FIELD: construction.

SUBSTANCE: invention relates to construction. Panel with possibility of connection with similar panels for formation of coating includes located in the centre bearing base having upper side and lower side. Bearing base has means of mechanical connection in form of groove and ledge of sheet connection arranged on opposite ribs of panel. Sheet metal ledge projection located in direction parallel to upper side has rounded front area and lower area. Lower back area of ledge of sheet connection made as support area is located closer to level of upper side of panel in comparison with lower part of lower front area, and the slot is made in the form of a recess for insertion of the ledge of the sheet-connection of the next panel with adhesion of adjacent panels in the place of joining the ribs, wherein said recess is formed by an upper projection and a lower protrusion, and said lower protrusion has an upwardly projecting edge to support the sheet connection ledge support region. Part of the end surface of the panel under the ledge of the tongue-and-groove connection is inclined and is adapted for contact in the assembled state with part of the inclined end surface under the slot of the other panel with formation of a gap. Lower side of the base is made with corrugation formed by alternation of protrusions and hollows with rectangular cross-section. Connection of panels for formation of coating includes the following stages: ledge of sheet connection of second panel is inserted into slot of first panel in inclined position, then the second panel is tilted down to the end position, while continuing to insert the tongue of the sheet-connection connection into the slot, shifting the edge portion of the second panel along the edge portion of the first panel along the long side before joining with the edge portion on the short side of the third panel, as a result of which there is mutual mechanical fixation of panels on both long and short sides of panels, the operations are repeated to add the following panels.

EFFECT: invention allows improving floor coating reliability during operation.
