Problems solved by technology
Similarly, this kind of plastic formwork only considers that the top plate of the formwork is not easy to be damaged or only meets the requirements of construction compressive loads. Although the hollow rods with conical downward openings can be conveniently stacked and transported, it does not consider the formwork. It is designed as the main load-bearing component and combined with the cast-in-place reinforced concrete structure to form a common three-dimensional force-bearing structural system to resist various complex external forces, especially the up-and-down pull force and horizontal shear force that cannot be resisted in the formwork.

The stereo force bearing reinforced concrete floor slab includes in-situ grouted reinforced concrete upper plate, in-situ grouted reinforced concrete ribs, and shuttering cavities. The spaced shuttering cavities, the in-situ grouted reinforced concrete ribs and the in-situ grouted reinforced concrete upper plate are grouted integrally. The shuttering cavity is polyhedron comprising top board, side walls and bottom board, and has at least one rod inside it. The present invention features that the rod inside the shuttering cavity is curved rod, bent rod, cable, prismatic straight rod, varying cross section straight rod, hollow rod or their combination; the bottom board has unequal thickness; and at least one side wall of the shuttering is on the thin bottom board.
Description
[0001] This application is a divisional application of an invention patent application with an application date of April 30, 2002, an application number of 02117549.7, and a title of "a reinforced concrete three-dimensional load-bearing structure floor". (1) Technical field [0002] The invention relates to a reinforced concrete three-dimensional load-bearing structure floor. (2) Background technology [0003] At present, most buildings with brick-concrete structure and frame 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 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 floors (solid...
