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 reinforcing rib vein on 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, in the same time, the strengthening pole subject and spread the force of building plank in the mould hull, improved the mechanics function of the building plank consumedly, in addition, the building plank still has the character of structure is simple, the strength is high, the anti- transform, anti- vibrate the function is good, construction convenience etc.

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, there is no reinforcing structure in the formwork components in this floor slab, the overall strength and stiffness of the formwork components are relatively poor, and the overall strength and stiffness of the corresponding floor slabs are relatively poor. During the construction process of the floor slab, the formwork components are prone to damage. , and at the same time, it cannot participate in the force and force transmission of the cast-in-place concrete hollow floor
