FIELD: construction.SUBSTANCE: invention relates to construction, particularly to flat concrete coverings containing reinforcement counteracting to transverse forces and pushing. In reinforcement, lattice girder is included extending to vertical axis of support and containing lower belts and one solid top belt, or fastening elements arranged via intervals, as well as at least one turn of diagonal braces, containing top and bottom bends respectively located between two following one after another diagonal braces. Bends are fixed at points of fixation, and diagonal braces are inclined in same direction up towards support, and diagonal brace closest to support is inclined relative to lower belts with more steep angle.EFFECT: remote from support diagonal brace is inclined with more flat angle, so that of attachment zones in concrete, formed by diagonal brace closest to support, upper area of fixing in concrete is located closer to vertical axis of support, than lower zone of fixing in concrete.17 cl, 12 dwg |
