Problems solved by technology

However, since the square opening formwork surrounded by the upper plate and the surrounding side plates in the floor slab is a one-time forming integral opening formwork, it is troublesome to make and the cost is relatively high. Therefore, it is necessary to develop a A new type of cast-in-place concrete hollow slab is urgently needed

Embodiment Construction

[0064] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0065] As shown in the accompanying drawings, the present invention includes reinforced concrete 1, open formwork components 2, the open formwork components 2 are wrapped in the reinforced concrete 1, and the open formwork components 2 are cast-in-situ reinforced concrete formed by reinforced concrete 1 The rib 3 is characterized in that the open formwork member 2 is a U-shaped groove member, including a U-shaped groove 4, a prefabricated transverse groove end plate 5 or a prefabricated transverse groove middle plate 6, and the bonding material of the U-shaped groove 4 The pulp body wraps the three side plate edges of the prefabricated transverse groove end plate 5 or the prefabricated transverse groove middle plate 6, and there is a bonding joint 7 between the embryo body and the prefabricated plate between the three side plate edges and the U-shaped gr...

Abstract

The invention relates to cast-in-site concrete hollow slob. Its features are that the opening shuttering component includes U shape slot one which includes U shape slot and ready made lateral slot end or center plate of which three side plate edges is covered by bonding paste embryo proper; between them binding seam of the embryo proper and ready made plate is set; at least one of the U shape slot, and ready made lateral slot end or center plate contains reinforce. Thus the cast-in-site concrete hollow slob of the invention has the advantages of simple manufacture, low cost, high strength, good anti vibration ability, simple structure, convenient construction, fast construction speed, can be used in various cast-in-site or pre-stress reinforced concrete hollow storey cover, house cover, sole plate, wall body, hollow bridge, especially for hollow mushroom floor.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow 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 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 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 const...
