FIELD: civil and industrial building, particularly composite panels adapted to consolidate ground embankments, sports ground, footpaths, access roads and so on.
SUBSTANCE: panel comprises four-edge cells. Each edge is shaped as three-dimensional harmonic in plan view, wherein harmonic length is equal to one or multiple half-periods of harmonic having amplitude equal to zero in connection rib defined between two adjacent cells. Axes of three-dimensional harmonics are inclined to panel sides at 45°. Disc-like support plates having centers coinciding with centers of adjacent cell connection ribs are formed on lower end panel side. Fixers are formed on panel edges projecting from panels along panel perimeters. The fixers are arranged on at least each second cell and adapted to connect panels offset one from another at opposite panel sides. The fixers are made as support discs provided with transversal and longitudinal movement limiting extensions.
EFFECT: improved performance, increased service life and simplicity of extended ground covering connection.
