Embodiment Construction

[0067] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0068] 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 at least two or more cavity formworks 1 are arranged alternately on the structural bottom plate 2. The interphase cavity between the cavity formwork 1 and the structural bottom plate 2 constitute the inner rib cavity 3 of the cast-in-place structure. The cavity formworks 1 are connected to each other, at least two or more braces 4 are arranged on the same straight line, and the cavity formworks 1 are arranged longitudinally and coaxially. In each accompanying drawing, 1 is a cavity formwork, 2 is a structural bottom plate, 3 is an inner rib cavity, and 4 is a brace member. In the following drawings, those with the same number have the same d...

Abstract

The present invention relates to a hollow cavity member for hollow plate. It includes hollow cavity forms and structural baseplate, the hollow cavity forms and structural baseplate are connected into whole body, on the structural baseplate at least more than two hollow cavity forms are alternatively arranged, the alternative hollow cavities between the hollow cavity forms and structural baseplate are formed into the poured-in-place structure inner rib mould cavities. It is characterized by that in every described inner rib mould cavity at least one bracing component is set. The invented hollow cavity member is applicable to cast-in-situ 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...
