Problems solved by technology

In the floor, the hollow cavity member is purely used as a formwork member and does not participate in the force bearing. When it is applied to a large space structure floor, its mechanical performance will also deteriorate accordingly, and there is no gap between the cast-in-place main ribs. Rib connection, so the size of the main rib needs to be increased accordingly, or the number of main ribs increases, resulting in increased material consumption, increased floor thickness, and increased cost

Embodiment Construction

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

[0061] As shown in the accompanying drawings, the present invention includes a formwork component formed by connecting formwork (1) and a structural bottom plate (2), and a cast-in-place reinforced concrete main rib (3), and is characterized in that it also includes a cast-in-place reinforced concrete The upper plate (4) includes at least two prefabricated cavity formworks (1) arranged alternately on the same prefabricated structural bottom plate (2) and at least one cast-in-place reinforced concrete secondary rib (5). The ribs (5) and the side walls of the cavity formwork (1) are superimposed on each other, and the cast-in-place reinforced concrete main ribs (3) and the cast-in-place reinforced concrete secondary ribs (5) constitute the interlaced primary and secondary hidden ribs of the spatial structure floor structure. figure 1 Four prefabricated cavity formworks (...

Abstract

A building roof with space structure is coposed of molded waffle members consisting of molded waffle and bottom plate, in-situ cast primary reinforced concrete rib, and in-situ cast reinforced concrete top plate. A prefabricated structured bottom plate has at least 2 molded waffle cavities and at least one in-situ cast secondary reinforced concrete rib. The said primary and secondary ribs constitute a hidden dense rib structure. Its advantages include high anti-earhquake performance and less thickenss, high strength.

Description

(1) Technical field [0001] The invention relates to a space structure floor. (2) Background technology [0002] At present, most buildings with brick-concrete structure and reinforced concrete structure use prefabricated hollow 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. deadline.
