Description

 Technical field of formwork structural member for reinforced concrete space structure floor

 The invention relates to a formwork structural member for a reinforced concrete space structure floor. Background technique

 At present, most buildings of brick-concrete structures and frame structures use prefabricated hollow slabs as floor covers. Such floor covers have the advantages of fast construction speed and low cost. However, because there is no solid connection between two adjacent prefabricated hollow slabs and the joints are filled with cement sand paddles only, 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 used cast-in-place concrete floor slabs (solid, hollow). Although the problems of earthquake resistance and cracking have been solved, the use of large-scale formwork during construction not only increases costs, but also slows down the construction speed. Extension of the construction period. The utility model patent for the "mold shell member" with the patent number of 93206310.1 discloses a prefabricated filling member for the multi-rib cavity cavity floor of industrial and civil buildings, which is composed of an upper bottom, a lower bottom and a side wall. The side wall, the upper bottom and the lower bottom form a fully enclosed cavity polyhedron structure, and a reinforcing rib is provided in the mold shell to enhance the overall support strength of the mold shell member. During construction, according to the design requirements, the shell members are placed on the support between the floors, a certain gap is left between the shell members, the reinforcement is arranged, and the concrete is poured. The shell members and the reinforced cement together form the upper and lower parts. The overall two-way multi-ribbed floor slab structure with a very flat surface. The formwork members are both internal molds and filling supporting members in the floor slab. The construction is labor-saving and simple. However, after this formwork member is applied to the cast-in-situ reinforced concrete space structure floor, the floor cover formed is relatively heavy, and the wall thickness of the polyhedron structure is not designed according to the actual stress and use requirements, that is, the thickness of the lower floor should be greater than Other wall thicknesses are conducive to the fact that the bottom can withstand large floor stresses and hang objects of a certain weight, such as lamps, ceiling fans, equipment, pipelines, etc. without cracking in actual use. Therefore, a new type of existing Moulded structural members for cast-in-place reinforced concrete space structures have been urgently needed. Summary of the Invention

The object of the present invention is to provide a formwork structural member for a reinforced concrete space structure floor, which is relatively light in weight when it is applied to a cast-in-situ reinforced concrete space structure floor and has light weight, high strength, and simple structure. Features such as convenient construction and transportation, meanwhile, it also has the feature that the cast-in-situ and prefabricated joint surface of the lower bottom surface of the cast-in-situ reinforced concrete space structure floor after hanging objects does not crack, and can transmit the force of the space structure floor. Point.

 The solution of the present invention is based on the prior art, and includes an upper bottom, a lower bottom, and a sidewall.

A protruding module and at least one vertical mold cavity or inclined mold cavity or a combination of both, and the lower bottom is a structural floor, and the thickness of the floor is greater than the thickness of the upper floor and the thickness of the surrounding sidewalls. Because the surrounding side wall has a protruding module and a vertical rod cavity, an inclined rod cavity or a vertical rod cavity and an inclined rod cavity formed by the module or the module and the side wall, this type of mold shell structural member is applied to After the reinforced concrete space structure floor, the cast-in-situ concrete two-way dense ribs formed between the structural components of the shell in the floor become the truss member-type two-way dense ribs, or the two-way dense ribs with truss-shaped members on both sides, Therefore, the weight of cast-in-place bidirectional dense ribs is greatly reduced, and the weight of the entire floor slab is also reduced. At the same time, the lower bottom is the structural floor, and the thickness of the structural bottom is greater than the thickness of the surrounding side walls and the upper bottom. Therefore, the entire structural member of the mold shell has high strength, more reasonable force transmission, and simple structure. In actual use, the structural floor can participate in the stress, and can hang a larger weight object without cracking the cast-in-place and prefabricated surface of the lower bottom surface of the cast-in-situ reinforced concrete space structural floor, thereby achieving the object of the present invention.
