Problems solved by technology

Because the prefabricated hollow slab is a one-way load-bearing prefabricated slab, the prefabricated slab cannot bear two-way loads. At the same time, when the prefabricated slab bears a large load, it is easy to generate cracks at the splicing parts

Embodiment Construction

[0052] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0053] As shown in the accompanying drawings, the present invention includes a basin-shaped component 1, which is characterized in that the basin-shaped component 1 is an integral component, and the basin-shaped component 1 is separated by at least two integral horizontal cross-sections of square, rectangular or circular basin side walls 2 It is arranged on the same integral bottom plate 3, and when the pot side wall 2 is cast-in-place and not hardened, the cover plate 4 is superimposed on it. In each accompanying drawing, 1 is a pot-shaped component, 2 is a basin side wall, 3 is a bottom plate, and 4 is a cover plate. In each accompanying drawing below, those with the same numbering have the same description. As shown in Figure 1, the hollow prefabricated slab includes a basin-shaped component 1, which is characterized in that the basin-shaped componen...

Abstract

Disclosed is a hollow prefabricated slab comprising a basin shape member (1), characterized in that the basin shape member (1) is an integrated member, at least two integral basin side panels (2) having square, rectangular or circular shape horizontal sections are arranged at intervals on a same integral bottom board (3). Before the basin side panels (2) are hardened during casting, a cover (4) is overlapped thereon. The invention can be applied to cast-in-situs reinforced concrete or prestressed reinforcement concrete lightweight boards, hollow building covers, house roofings, foundation slabs, walls and hollow bridges. especially for hollow flat slabs.

Description

(1) Technical field [0001] The invention relates to a hollow prefabricated panel. (2) Background technology [0002] At present, reinforced concrete assembled hollow-core slabs use short prefabricated hollow-core slabs to assemble large-span reinforced concrete hollow-core slabs, and the cost is low and the construction is convenient. Invention patent, this kind of floor is composed of multiple hollow prefabricated slabs assembled vertically and horizontally, cushion blocks are arranged at the ends of two adjacent rows of hollow prefabricated slabs, and the longitudinal connection of two adjacent hollow prefabricated slabs is filled with cast-in-place concrete. Longitudinal steel bars are placed between two rows of hollow prefabricated slabs, and the anchors are set on the steel bars and supported on the ends of the hollow prefabricated slabs. Since the prefabricated hollow slab is a unidirectional load-bearing prefabricated slab, the prefabricated slab cannot bear two-way ...
