Reinforcing bar lightweight concrete board

Abstract

A reinforced concrete lightweight slab, comprising cast-in-place reinforced concrete (28), prefabricated components (29) for filling, the prefabricated components (29) for filling are arranged alternately and wrapped in cast-in-place reinforced concrete (28), filled The prefabricated components (29) are cast-in-place concrete ribs (30) between each other, and it is characterized in that there is a passage in the same direction as the vertical vertical plate (2) in the concrete bottom plate (1) at the intersection with the concrete vertical vertical plate (2). The long steel bar (3), the concrete vertical vertical plate (2) has a transverse rib cavity (4), the transverse rib cavity (4) has a tie pier (5), and the concrete bottom plate (1) has a filling body (6 ), the concrete bottom plate (1) protrudes longitudinally out of the filling body (6) to form a raised edge (7) or / and the concrete vertical vertical plate (2) extends out of the filling body (6) to form a raised edge (8), and the filling body (6) have transverse rib cavity (31) to communicate with transverse rib mold cavity (4) between, the cast-in-place concrete inner rib (32) formed in transverse rib cavity (31) links to each other with cast-in-place concrete rib (30). Suitable for hollow floors, roofs, walls, etc.

Description

(1) Technical field [0001] The invention relates to a reinforced concrete lightweight board. (2) Background technology [0002] The floor slab is assembled with ribbed reinforced concrete prefabricated components, which can withstand two-way loads, does not require on-site formwork, and is low in cost, easy to hoist and transport. The prefabricated component with ribs comprises a concrete bottom plate and at least one concrete vertical vertical plate. The concrete vertical vertical plate stands on the concrete bottom plate and is connected with the concrete bottom plate as a whole. Usually the length of the concrete vertical vertical slab of this prefabricated component is the same as the length of the concrete bottom slab. When this prefabricated component is assembled to form a floor slab bearing two-way loads, the cast-in-place concrete cannot pass through the vertical slab and cannot form a connected vertical vertical slab with the concrete. At the same time, in the dir...

AI Technical Summary

Problems solved by technology

Usually the length of the concrete vertical vertical slab of this prefabricated component is the same as the length of the concrete bottom slab. When this prefabricated component is assembled to form a floor slab bearing two-way loads, the cast-in-place concrete cannot pass through the vertical slab and cannot form a connected vertical vertical slab with the concrete. At the same time, in the direction perpendicular to the vertical slab, various pipeline layouts need to be drilled and threaded on site, which not only wastes concrete materials, but also wastes man-hours. Moreover, after the cast-in-place concrete, the assembled floor is solid , Concrete consumes a lot of materials, and the weight of the floor slab is heavy, so it is not suitable for large-span pouring. Therefore, it is urgently needed to develop a new type of reinforced concrete lightweight slab
