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, which is not suitable for large-span pouring. Therefore, it is urgent to develop a new type of concrete hollow slab.

Embodiment Construction
[0049] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0050] As shown in the accompanying drawings, the present invention includes cast-in-place reinforced concrete 20, cavity members 21 for filling, the cavity members 21 for filling are arranged alternately and wrapped in the cast-in-place reinforced concrete 20, and the cavity members 21 for filling are mutually arranged. There are cast-in-place concrete ribs 22 between them, and the cavity member 21 for filling includes a reinforced concrete bottom plate 1 and at least two reinforced concrete side plates 2. The elongated groove of the elongated grooved plate member is filled with at least two grooved overhead slabs 3 with openings facing downwards, and there is at least one longitudinally long prestressed steel bar 4 in the bottom plate 1 of the bottom of the side plate 2 , the top of the side plate 2 has at least one longitudinally long prestressed ste...

A hollow reinforced concrete comprises concrete cast in site, pre-fabricated components as fillers spaced each other and contained in the former, and some ribs are cast in site between the said fillers. Some components like slots, at least two, are put downward in long channels to be separated each other with narrow spaces, which are filled with concrete cast in site. At least one steel bar from one end to the other is respectively arranged the upper and lower portions of the side walls. Some notches on the side walls are used to form connection with some connecting piers. The concrete can be used as roof.
Description
(1) Technical field [0001] The invention relates to 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 side plate, various pip...
