摘要
FIELD: civil engineering. SUBSTANCE: grate reinforcement for concrete slab has spaced flat bridges of similar width and zigzag-shaped reinforcing bars welded to the bridges on their sides. Apices of the zigzags are projected over the flat bridges to keep concrete form plates apart from the flat bridges to place concrete between the concrete form plates and the flat bridges. The spacing is 15 - 50 mm. Reenforcing zigzags may be shifted along lengthwise direction by half distant between apices of each other and bent outside. Grate reinforcement may be additionally provided with rods welded on outer sides of reinforcing bars in the area of flat bridge to fasten to ceiling slab. Plate- type member of wall concrete form includes concrete form plates and grate reinforcement placed between. The member is provided with flat bridges placed between plates and parallel to them. Zigzag-shaped reinforcement is attached to the bridges. The zigzags are projected over flat bridges to interconnect them to one another. Fastening members are made in the form of screws and split pins. Displacing body glued on concrete form plate between two reinforcing structures is placed. The plate is set in concrete. EFFECT: high reliability. 18 cl, 11 dwg
