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 strengthening veinon the prefabricate lamella.Thus, the strength of the prefabricate lamella is high, the firm degree is big, it's not easy to come forth of craze, even affecting the external appearance quantity of the building plank ceiling etc., at the same time, the structure of building plank is simple, the strength is high, the anti-transform, anti- vibrate the function is good, construction convenient.

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...
