FIELD: civil engineering. SUBSTANCE: reinforced concrete structure can take the form of floor or ceiling slab, road base slab, shaped load-bearing girder having upper reinforcement layer with longitudinal and lateral reinforcing rods, and lower layer in the form of bow- shaped longitudinal reinforcing rods connected with upper layer by lateral rod. Longitudinal rods of upper and lower layers are connected to lateral rod by welding. Curvature of lower rods, depending on load distribution, can be of varied rate. EFFECT: high efficiency. 1 cl, 4 dwg |
