The invention discloses a reinforced concrete lightweight board, which comprises reinforced concrete (1) and solid lightweight components (2), wherein the solid lightweight components (2) are wrapped in the reinforced concrete (1) and are arranged at intervals, and cast-in-place reinforced concrete ribs (3) are arranged among the solid lightweight components. The reinforced concrete lightweight board is characterized in that: a cantilever slab (6) protrudes outwards along a bottom surface (5) on the circumferential lateral surface of at least one of the solid lightweight components (2); the bottom surface (5) is leveled with the bottom surface of the reinforced concrete lightweight board; the cantilever slab (6) is formed by setting and connecting the solid lightweight components (2) to a cement mortar or a cement concrete bottom plate (8); and the solid lightweight components (2) are foamed plastic blocks, expanded perlite blocks, expanded vermiculite blocks, foamed or aerated concrete blocks, haydite concrete blocks, straw husk cementing material blocks, charcoal concrete blocks or cement-cemented foam grain blocks. The reinforced concrete lightweight board is suitable for cast-in-place reinforced concrete or prestressing force reinforced concrete lightweight boards, floor systems, roofs, wall bodies, foundation slabs and bridges, and is particularly suitable for flat slabs.

Disclosed is a cast-in-situ concrete slab, which comprises a reinforced-bar concrete (1) and shuttering members (2), the shuttering members (2) comprise an upper board (3) and peripheral side panels (4), the upper board (3) and the peripheral side panels (4) encloses an open basin shape component, cast-in-situ reinforced bar concrete ribs (5) formed by the reinforced-bar concrete (1) are disposed between the peripheral side walls (4) of the shuttering members (2), cast-in-situ reinforced bar concrete overlapping layers formed by the reinforced-bar concrete (1) are disposed above the upper board (3) of the shuttering members (2), and is connected to the cast-in-situ reinforced bar concrete ribs (5), the reinforced-bar concrete (1) and the shuttering members (2) are superposed into an integrity, characterized in that a decorative carving is arranged on the inner surface of the cavity of the basin form component, the invention can be applied to cast-in-situ reinforced concrete or prestressed reinforcement concrete's hollow storied-building roofings, house roofings, walls, foundation bedplates and hollow bridges, especially for hollow flat slabs.

Disclosed is a reinforced-bar concrete hollow slab, which comprises a reinforced-bar concrete (1) and hollow members (2), the hollow members (2) are enclosed in the reinforced-bar concrete (1), the hollow members (2) are arranged alternatively, and cast-in-situ reinforced-bar concrete rib (3) is arranged between them, the hollow members (2) comprise an upper board (4), peripheral side panels (5), and a lower bottom (6), the upper board (4), the peripheral side panels (5), and the lower bottom (6) enclose a polyhedral hollow member, the invention is characterized in that at least a recess (7) is arranged between the side panels (5) and the lower bottom (6), a reinforced structure (8) of the reinforced-bar concrete hollow slab is formed on the recess (7) position of the cast-in-situ concrete, a reversed T-shape rib is formed by the cast-in-situ reinforced bar concrete rib (3) together with the reinforced structure (8) on the corresponding sites, the lower bottom (6) is provided with at least one prestressed rib (9). The invention can be applied to cast-in-situs reinforced concrete or prestressed reinforcement concrete's hollow boards, storied building covers, house roofings, walls, foundation bedplates and hollow bridges, especially for hollow flat slabs.
