Reinforced bar concrete solid load-carrying structural storied building cover

Abstract

Disclosed is a reinforced concrete slab floor with three-dimensional force-bearing structure, which comprises a cast-in-situ reinforced concrete upper slab (1), a cast-in-situ reinforced concrete rib (2), and hollow formworks (3) arranged at intervals between which the cast-in-situ reinforced concrete rib (2) is arranged, and a cast-in-situ reinforced concrete upper slab (1) is arranged above, the three elements are cast into an integrity, wherein the cavity forms (3) comprise an upper top board (4), peripheral side panels (5) and a lower bottom (6), which are linked each other to form a polyhedral closed cavity (7), the invention is characterized in that the rod unit (8) in the cavity (7) is a curved rod, a folded-line rod, a cable, an equal-cross-sectional straight rod, a variable cross-sectional straight rod, an upper-opened hollow rod or their combination, or the combination of a variable cross-sectional hollow straight rod with the above-mentioned rod units, the upper top board (4) is provided with a central hole at the central position, the bar member (8) exposes outward from the center hole.

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...

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.
