Problems solved by technology

However, during the handling, construction and long-term use of such cavity components, the structural bottom plate is prone to breakage, so the damage rate of the cavity components is high, and the handling and construction are inconvenient, which increases the construction cost. Cracks will affect the appearance quality of the floor ceiling

Embodiment Construction

[0077] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0078] As shown in the accompanying drawings, the present invention includes a cavity formwork 1 and a base plate 2, the cavity formwork 1 and the base plate 2 are connected as a whole, and at least two cavity formworks 1 are arranged alternately on the base plate 2, and its side faces and the base plate 2 Constitute at least one cast-in-place structure inner rib cavity 3, and the other outer surface 4 of the cavity formwork 1 constitutes the side formwork of the cast-in-place structure outer rib or beam or wall, which is characterized in that the bottom plate 2 is sandwiched by at least one prestressed Tendon 5. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In the accompanying drawings, 1 is the cavity formwork, 2 is the bottom plate, 3 is the inner rib cavity of the cast-in-place structure, 4 is the outer sur...

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 inner rib die cavity (3), while the other outer side faces compose the side die plate of on-site casting structure outer rib, beam or wall. And the base plate (2) holds at least one tendon (5), as a result, the cavity component has bigger strength, rigidity and shock resistance, the structural base plate is hard to be broken, and the floor has good crack resistance when applying the component, furthermore, the component has the characters of simple structure, easy making, low costs, etc. The invention is suitable for hollow floor, roof, soleplate, wall and empty bridge with on-site casting reinforced concrete or prestressed reinforced concrete.

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...
