Embodiment Construction

[0061] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0062] As shown in the accompanying drawings, the present invention includes a cavity formwork 1 and a structural bottom plate 2. The cavity formwork 1 and the structural bottom plate 2 are connected as a whole, and the cavity formwork 1 is arranged on the structural bottom plate 2. The interphase cavity between the shells 1 and the structural bottom plate 2 constitute the inner rib cavity 3 of the cast-in-place structure, which is characterized in that at least one brace 4 is arranged in the inner rib cavity 3, and the adjacent cavity formwork 1 are connected to each other, the cavity formwork 1 is arranged longitudinally on the coaxial line, the cavity formwork 1 is a prefabricated open basin-shaped formwork, and the openings of at least two prefabricated open basin-shaped cavity formwork 1 are fastened together. The long structural bottom plate 2 of ...

Abstract

The present invention relates to a hollow cavity member for hollow plate. It includes hollow cavity forms and structural baseplate. Said hollow cavity forms and structural baseplate are connected into a whole body. On the structural baseplate the alternatively-arranged hollow cavity forms are set, the alternative hollow cavities between hollow cavity forms and structural baseplate are formed into poured-in-place structure inner rib mould cavities. It is characterized by that in every inner rib mould cavity at least a bracing component is set. The invented hollow cavity member is applicable to cast-in-place reinforced concrete or prestressed reinforced concrete hollow plate, hollow floor board, roof slab, foundation baseplate, wall body and open-web bridge.

Description

(1) Technical field [0001] The present invention relates to a cavity member for a hollow plate. (2) Background technology [0002] At present, most of the buildings with brick-concrete structure and reinforced concrete structure use prefabricated hollow slabs as floor slabs. This floor slab has 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 construc...
