Problems solved by technology
Usually the length of the side plate of this prefabricated component is the same as the length of the bottom plate. When this prefabricated component is assembled to form a lightweight slab bearing two-way loads, the cast-in-place concrete cannot pass through the side plate, and cannot form a connected crossing with the side plate. Cast-in-place concrete ribs, at the same time, in the direction perpendicular to the side plate, various pipeline layouts need to be drilled and threaded on site, which not only wastes concrete materials, but also wastes man-hours. Moreover, after cast-in-place concrete, the assembled lightweight panels are solid. Concrete consumes a lot of material, and the lightweight slab is heavy, so it is not suitable for large-span pouring. Therefore, it is urgently needed to develop a new type of cavity member for concrete hollow slabs.

Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0027] As shown in the accompanying drawings, the present invention includes a reinforced concrete bottom plate 1, at least two reinforced concrete side plates 2, and the side plates 2 stand upright on the bottom plate 1 to form a strip-shaped channel plate member, which is characterized in that the strip-shaped channel plate The elongated groove of the member is filled with at least two groove-shaped overhead plates 3 with openings downward, the bottom plate 1 at the bottom of the side plate 2 has at least one longitudinally long prestressed steel bar 4, and the top of the side plate 2 has At least one longitudinally long prestressed steel bar 4, open groove-shaped overhead plates 3 are arranged at intervals, and at least one inner rib cavity 5 is left between the open groove-shaped overhead plates 3, and the inner rib cavity 5 and the side plate 2 The...

A hollow component used for hollow reinforced concrete consists of a substrate, at least two reinforced concrete side walls, which are arranged on the said substrate so as to form a slender trough. At least two downward over-linked plates are filled in the trough. At least one pre-stressed steel bar is respectively arranged in the substrate and on the top of each side wall. The over-linked plates are spaced each other to form at least one internal rib cavity to connect with internal reinforced holes on the side walls and two longitudinal edges are formed on the substrate by extending out of the substrate. It can be used for hollow board, roof, substrate, wall or hollow bridge beam.
Description
(1) Technical field [0001] The invention relates to a cavity component for a concrete hollow slab. (2) Background technology [0002] Ribbed reinforced concrete prefabricated components are used to assemble lightweight slabs, which can bear two-way loads, do not need on-site formwork, and are low in cost, easy to hoist and transport. This ribbed prefabricated component includes a strip-shaped bottom plate and a long strip-shaped side plate, and the side plate and the bottom plate are connected as a whole to form a T-shaped or long-strip trough-shaped component. Usually the length of the side slab of this prefabricated component is the same as the length of the bottom slab. When this prefabricated component is assembled to form a lightweight slab that bears two-way loads, the cast-in-place concrete cannot pass through the side slab and cannot form a connected intersecting slab with the side slab. In-situ concrete ribs, at the same time, in the direction perpendicular to the ...
