Problems solved by technology

However, during the handling and construction of the cavity components used in this hollow slab, the structural bottom plate is prone to breakage, so the damage rate of the cavity components is high, and the transportation and construction are inconvenient, which increases the construction cost of the hollow slab

Embodiment Construction

[0063]The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0064] As shown in the accompanying drawings, the present invention includes a cavity member 4 formed by connecting a reinforced concrete 1, a cavity formwork 2 and a structural bottom plate 3, the cavity member 4 is wrapped in the reinforced concrete 1, and the structural bottom plate 3 has at least 2 The cavity form shells 2 are arranged alternately, and their side surfaces and the structural bottom plate 3 form at least one cast-in-situ structure secondary rib mold cavity 5. It is characterized in that at least one stretcher 7 is arranged in the secondary rib mold cavity 4 of the adjacent cavity formwork 2, which connects the adjacent hollow formwork 1 to each other and is wrapped in the cast-in-place reinforced concrete hidden rib 6. middle. FIG. 1 is a schematic structural diagram of Embodiment 1 of the present invention. In the accompanying drawing...

Abstract

The hollow reinforced concrete board includes reinforced concrete, and cavity member comprising connected cavity shuttering and structural bottom plate. The cavity member is coated inside the reinforced concrete. On the structural bottom plate, there are at least two alternately arranged cavity shutterings with side constituting at least one in-situ cast secondary ribbed cavity together with the structural bottom plate. The in-situ cast reinforced concrete forms in-situ reinforced concrete rib in in-situ cast secondary ribbed cavity. There is at least one support part coated inside the in-situ reinforced concrete rib to connect the adjacent open web shutternigs. The hollow board has the features of convenient construction and low cost, and is suitable for floor slab, roofing, base slab, wall and open web bridge of in-situ or pre-stressed reinforced concrete.

Description

(1) Technical field [0001] The invention relates to a reinforced concrete hollow board. (2) Background technology [0002] At present, most of the buildings with brick-concrete structure and reinforced concrete structure use prefabricated hollow-core slabs as floor slabs, which have the advantages of fast construction speed and low cost. However, because there is no firm connection between the two adjacent prefabricated hollow slabs, and only cement mortar is used to fill the joints, the integrity is poor, which is not conducive to earthquake resistance, and cracks and water seepage often occur. In order to solve the above problems, many buildings have adopted the method of cast-in-place concrete floor (solid, hollow), although the problems of earthquake resistance and cracking have been solved, but a large number of formwork must be used during construction, which not only increases the cost, but also slows down the construction speed and prolongs the construction. constru...
