Problems solved by technology

Although this kind of floor slab can save a lot of formwork and speed up the construction process, because the formwork and the prefabricated thin slab are separated, and there is no reinforcement in the formwork, there is a problem that...

Abstract

The invention relates to a precast hollow floor board with spatial structure and its application. The floor board includes hollow form and cavity, and features including structural bottom slab and structural sub-rib. The structural bottom slab and structural sub ribs contain reinforcing bars or wire mesh to form an integrated load-bearing member with an inverted T-shape. There are exposed bars ormesh on the structural bottom slab. The thicknesses of structure bottom slab and structural sub-rib are larger than the thickness of hollow form whose upper part and side parts are connected to the structural sub-rib, and lower part is connected to the structural bottom slab so as to form a closed integral body. The invented precast hollow floor board possesses advantages of simple structure, high strength, easy for handlings, good shock resistance and reduced structural dead wt..

Description

(1) Technical field [0001] The invention relates to a space structure floor prefabricated cavity component and its application. (2) Background technology [0002] At present, most buildings with brick-concrete structure and concrete structure use prefabricated hollow-core slabs as floor slabs, which have the advantages of fast construction speed and low cost. However, because there is no firm connection between two adjacent prefabricated hollow slabs, only cement mortar is used to fill the joints, so the integrity is poor, which is not conducive to earthquake resistance, and cracks and water seepage often occur in the gaps. In order to solve the above problems, many buildings adopt the method of cast-in-place concrete floor slabs (solid and hollow). Although the problems of earthquake resistance and cracking have been solved, a large number of templates are used during construction, which not only increases the cost, but also slows down the construction speed and prolongs th...
