Combined reinforced concrete hollow floorslab

Abstract

A kind of combined hollow building plank with reinforcing steel bar in it, comprises the prefabricate lamella, the mould hull, the hidden rib, the upper plank, the mould hull fixed on the prefabricate lamella, setting the hidden ribbetween prefabricate lamella and the mould hull ,and close together to them, overlaying the upper plank on the mould hull, and connect with the hidden rib for the integral whole, its characteristic lie in setting vertical arc corner in the vertical orientation corner of orientation mould hull,sprinkling in the vertical orientation arc corner to form the strengthen vein in intersect part of hidden rib, thus, can remove the dint concentrate phenomenon in cast-in-place concrete building cover availably, prevent the come into being of the crack, and can bear more concentrated stress but don't destroy.

Description

(1) Technical field [0001] The invention relates to a composite reinforced concrete hollow floor slab. (2) Background technology [0002] At present, most of the buildings with brick-concrete structure and frame structure use prefabricated hollow-core slabs as floor slabs. This kind of floor slab has the advantages of fast construction speed and low cost, but because there is no firm connection between two adjacent prefabricated hollow-core slabs , Only cement mortar is used to fill the gaps, so not only the integrity is poor, which is not conducive to earthquake resistance, but also cracks and water seepage often occur, causing great inconvenience and psychological pressure to the residents. In order to solve the above problems, many buildings have adopted the method of cast-in-place concrete floor slabs (hollow, solid). Although the cast-in-place concrete floor slab solves the problems of earthquake resistance and cracking, a large number of templates are used during cons...

AI Technical Summary

Problems solved by technology

However, at the vertical corners of the formwork, the stress of the floor is more complicated, the stress is more concentrated, and cracks are easy to occur, or even cracked and damaged.
