Problems solved by technology

However, since the formwork in the floor slab needs to be fixed on the prefabricated thin slab on site, the construction is troublesome. At the same time, the weight of the prefabricated thin slab is relatively heavy, and the transportation is time-consuming and laborious. These will bring inconvenience to the construction and transportation and increase the construction cost.

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 an upper plate 1 and a surrounding side wall 2, and is characterized in that it also includes a lower bottom 3. The upper plate 1, the surrounding side walls 2, and the lower bottom 3 form a polyhedral structure with a cavity 4, and at the same time At least one thin strip 5 is sandwiched in the lower bottom 3 . figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In the accompanying drawings, 1 is an upper plate, 2 is a surrounding side wall, 3 is a bottom, 4 is a cavity, 5 is a thin strip, and the same numbers have the same description. figure 1 Among them, the upper plate 1, the surrounding side walls 2, and the lower bottom 3 form a polyhedral structure with a cavity 4, and a plurality of thin strips 5 are sandwiched in the lower bottom 3...

Abstract

A thin-wall hollow form for concrete to in-situ pour hollow non-beam floor is composed of top plate, peripheral wall and bottom plate, and is characterized by that its bottom plate contains at least one thin strip for improving its resistance to impact and collision. Its advantages are simple structure, high strength, toughness and resistance to deformation and vibration, light weight and low cost.

Description

(1) Technical field [0001] The invention relates to a thin-walled formwork component for hollow concrete. (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 u...
