Problems solved by technology

If the prefabricated thin slab is removed, the floor slab becomes a densely ribbed slab; if wires, switches and other components are installed on the densely ribbed slab, it is often necessary to drill holes in the newly repaired cast-in-place concrete hollow slab. Difficult to install and cumbersome to repair

Abstract

The invention is a cast-in-site concrete hollow slab, comprising reinforced concrete, prefabricated sheets, and form components, where the prefabricated sheets are horizontally and staggeredly arranged, the form components are arranged on the prefabricated sheets, the reinforced concrete forms cast-in-site reinforced concrete ribs between the form components, and each form component comprises top plate and peripheral side wall, which compose an open basin-like component, and it is characterized that at least one of the top plate and peripheral side wall is provided with connection box or pipeline, and the bottom surface of the prefabricated sheet is on the same plane with that of the cast-in-site hollow slab. And the invention is applied to cast-in-site reinforced concrete or prestressed reinforced concrete floor systems, house covers, walls, foundation slabs and hollow bridges, especially applied to ribbed floor systems.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0002] At present, most buildings with brick-concrete structure and frame structure use prefabricated hollow slabs as floor slabs. This kind of cast-in-place concrete hollow slab has the advantages of fast construction speed and low cost. However, due to the gap between two adjacent prefabricated hollow slabs There is no firm connection, and only cement mortar is used to fill the gaps. Therefore, not only the integrity is poor, which is not conducive to earthquake resistance, but also cracks and water seepage often occur in the gaps, 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 hollow slabs. Although the cast-in-place concrete hollow slab solves the problems of earthquake resistance and cracking, a large number of templates are u...
