Problems solved by technology

The prefabricated hollow slab is composed of steel bars and concrete, and is produced by mould, including a strip-shaped slab body. There are at least two rows of longitudinal long tube holes in the long strip-shaped slab body. Such prefabricated hollow slabs are arranged on load-bearing walls or beams. On the other hand, the gaps between the prefabricated hollow slabs are poured with cast-in-place concrete, and the formed hollow floor or roof, because there is no firm connection between the prefabricated hollow slabs and the hollow slabs, it is easy to produce cracks along the slabs, and the overall floor Poor performance, poor seismic performance, especially the large difference in vertical and horizontal stiffness of the floor or roof

Embodiment Construction

[0203] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0204] As shown in the accompanying drawings, the present invention includes a strip-shaped plate body 1, and there are at least two rows of longitudinal long tube holes 2 in the longitudinal direction in the strip-shaped plate body 1, and it is characterized in that at least one transverse rib mold hole 3 runs through the plate body transversely 1. In each accompanying drawing, 1 is an elongated plate body, 2 is a longitudinal elongated pipe hole, and 3 is a transverse rib die hole. In the following accompanying drawings, those with the same numbering have the same description. Such as figure 1 As shown, it includes a strip-shaped plate body 1, and there are many rows of longitudinal long tube holes 2 in the strip-shaped plate body 1, and two transverse rib mold holes 3 are also arranged to transversely penetrate the plate body 1.

Abstract

A precast hollow slab includes pencil shaped slab body. It is featured as setting at least two rows of longitudinal pipe holes in said slab body and setting at least one line of horizontal rib die holes through slab body in said slab body.

Description

(1) Technical field [0001] The invention relates to a prefabricated hollow plate and its production mold, production method and application. (2) Background technology [0002] At present, prefabricated hollow-core panels are mainly used in floors or roofs of buildings. The prefabricated hollow slab is composed of steel bars and concrete, and is produced by mould, including a strip-shaped slab body. There are at least two rows of longitudinal long tube holes in the long strip-shaped slab body. Such prefabricated hollow slabs are arranged on load-bearing walls or beams. On the other hand, the gaps between the prefabricated hollow slabs are poured with cast-in-place concrete, and the formed hollow floor or roof, because there is no firm connection between the prefabricated hollow slabs and the hollow slabs, it is easy to produce cracks along the slabs, and the overall floor Poor performance, poor seismic performance, especially the large difference in vertical and horizontal s...
