Problems solved by technology

The fully prefabricated hollow floor slab reduces the weight of the slab itself due to the cavity formed inside the slab. Compared with the laminated slab, it does not need secondary pouring, which is environmentally friendly and saves the construction period. Rebar and roof reinforcement, the construction efficiency is low, and the quality of the prefabricated hollow floor is difficult to guarantee

Abstract

The invention provides a prefabricated hollow slab, which comprises a top layer, a bottom layer, a hollow device and a special grid truss for the prefabricated hollow slab, wherein the hollow device is arranged between the top layer and the bottom layer; the special grid truss for the prefabricated hollow slab comprises two meshes in opposite and separated arrangement; at least one rib in vertical arrangement to the meshes is arranged between the two meshes; at least one penetrated transverse pipe is arranged on the pipe wall of the hollow device; and the hollow device is arranged between the two meshes. Therefore the prefabricated hollow slab can be formed through one-step casing in a prefabricated hollow slab forming mold; the occurrence of the condition of nonuniform prefabricated hollow slab hole wall cannot be caused; the at least one transverse pipe transversely penetrating through a pipe body is arranged on the pipe wall of the pipe body; a concrete post body can be formed in the prefabricated hollow slab; and two slab surfaces of the prefabricated hollow slab can be tensioned into a whole.

Description

technical field [0001] The invention relates to a building part, in particular to a prefabricated hollow board. Background technique [0002] my country's urbanization is developing rapidly, and its construction scale ranks first in the world. At present, the industrialization of construction is imminent, and the construction industry is transformed into green construction. It is very necessary to save energy and reduce emissions during the construction process, and to manufacture prefabricated hollow panels with excellent structural performance to build prefabricated buildings. [0003] At present, the reinforced concrete floor slabs used in China include cast-in-place slabs and prefabricated hollow-core slabs. The cast-in-place slabs have good integrity, but they need to be molded on site, and then poured concrete. The construction period is difficult, the loss of formwork is large, and the cost is high. The hollow slab does not require on-site formwork, the construction ...
