Embodiment Construction

[0070] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0071]As shown in the accompanying drawings, the present invention includes a cavity or solid formwork 1 and a structural bottom plate 2. The cavity or solid formwork 1 is connected to the structural bottom plate 2 as a whole, and there are at least two or more cavities or solid solid forms on the structural bottom plate 2. The mold shells 1 are arranged alternately, and the cavity or the interphase cavity between the solid mold 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 is arranged in the inner rib cavity 3 The puller 4 connects adjacent cavities or solid formworks 1 to each other, at least one row of cavities or solid formworks 1 is arranged longitudinally on the same axis, and the braces 4 are prestressed prestressed braces. In each dra...

Abstract

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