Problems solved by technology

However, after this kind of cavity member is applied to the hollow floor, since the formed cast-in-place concrete ribs are all rectangular ribs, its mechanical performance is not very reasonable. It is often necessary to increase the cross-sectional size of the ribs and increase the amount of steel bars and concrete. Increase the cost of the floor, therefore, it is urgently needed to develop a new cavity component

Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0055] As shown in the accompanying drawings, the present invention includes a cavity formwork 1 and a bottom plate 2. The cavity formwork 1 and the bottom plate 2 are connected as a whole, and at least two cavity formworks 1 are arranged alternately on the bottom plate 2. The opposite side of the adjacent cavity formwork 1 and the bottom plate 2 form at least one secondary rib cavity 3 of the cast-in-place structure, and the other non-opposite outer sides 4 of the cavity formwork 1 form the main rib or beam of the cast-in-place structure. The side formwork of the wall is characterized in that at least one side of the contact portion between the cavity formwork 1 and the bottom plate 2 is an indented groove 5 . Fig. 1 is a schematic structural diagram of Embodiment 1 of the present invention. In the accompanying drawings, 1 is the cavity formwork, 2 is...

Abstract

Disclosed is a cavity component, which comprises a cavity shuttering (1), and a base plate (2). The cavity shuttering (1) is integrated on the base plate (2), on the base plate (2), at least two cavity shutterings (1) are alternately arranged. One side face of the cavity shuttering (1) and the base plate (2) compose at least one on-site casting structure secondary rib die cavity (3), while the other outer side faces compose the side die plate of on-site casting structure main rib, beam or wall. And at least one side contacted by the cavity shuttering (1) and the base plate (2) is a groove. The on-site casting concrete rib forms an inversed T shape rib, the cross-section of which is changed from rectangle to inversed T shape when the cavity component is applied to the hollow floor, as a result, the mechanical properties of the floor is greatly improved and the reinforcing steel bar and concrete consumption are reduced. The invention is suitable for hollow floor, roof, soleplate, wall and empty bridge with on-site casting reinforced concrete or prestressed reinforced concrete, especially for hollow mushroom floor.

Description

(1) Technical field [0001] The present invention relates to a cavity member. (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. Applicatio...
