Embodiment Construction

[0060] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0061] As shown in the accompanying drawings, the present invention includes an upper plate 1, surrounding side walls 2, and a lower bottom 3. The upper plate 1 and the surrounding side walls 2 form a mold shell 4, and the mold shell 4 and the lower bottom 3 form a closed cavity 5. It is characterized in that the formwork 4 is spliced ​​and assembled by at least two segmented formwork panels 6 , and the segmented formwork panels 6 are molded parts including a part of the upper plate 7 and a part of the side wall 8 connected thereto. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In each drawing, 1 is the upper plate, 2 is the surrounding side wall, 3 is the lower bottom, 4 is the formwork, 5 is the cavity, 6 is the block formwork plate, 7 is part of the upper plate, 8 is part of the side Walls with the same numb...

Abstract

A hollow form for in-situ pouring concrete is composed of the form unit and bottom plate, and is characterized by that form unit consists of top plate and peripheral wall and is divided into two halves. Its advantages are simple structure, high strength, low cost and easy manufacture.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow formwork component. (2) Background technology [0002] At present, most buildings with brick-concrete structure and frame 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 the construction period. dea...
