Problems solved by technology

However, after this kind of cavity component is applied to the hollow floor, the cavity formwork and the cast-in-place concrete are embedded with each other, and the void phenomenon often occurs due to the shrinkage of the cast-in-place concrete after setting and hardening. not firm

Embodiment Construction

[0073] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0074] 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 the cavity formwork The side surface of 1 and the bottom plate 2 form at least one cast-in-place structure inner rib cavity 3, and the other outer sides of the cavity formwork 1 form the side formwork of the cast-in-place structure outer rib or beam or wall, which is characterized in that the cavity mold Shell 1 is a cavity formwork with corrugated walls. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In the accompanying drawings, 1 is the cavity formwork of the corrugated wall, 2 is the bottom plate, and 3 is the inner rib cavity of the cast-in...

Abstract

Disclosed is a cavity component, which comprises a cavity shuttering (1) and a base plate (2). The cavity shuttering (1) is integrated with the base plate (2), on which at least two cavity shutterings (1) is arranged with intervals. One side face of the cavity shuttering (1) and the base plate (2) compose at least one inner rib die cavity (3) with on-site casting structure, other side faces of the cavity shuttering (1) compose on-site casting structure outer rib or side die plate of beam or wall. Said cavity shuttering (1) has corrugated walls, as a result, the cavity shuttering increases contact surfaces with the on-site casting concrete when being applied to on-site casting concrete hollow floor, they are firmly fixed to each other. The invention has the advantages of easy making, low costs and so on. It is suitable for floor, roof, soleplate, wall or empty bridge, especially for mushroom floor.

Description

(1) Technical field [0001] The present invention relates to a cavity member for a hollow plate. (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. de...
