Reinforcing-bar concrete building roof with tree-dimensional bearing structure

Abstract

A reinforced concrete stereoscopic bearing structure building floor, including cast-in-place reinforced concrete top plate(-), cast-in-place reinforced concrete rib (-), and hollow pattern shell (-), hollow pattern shell(-) arrange on line at regular interval, cast-in-place reinforced concrete rib (-) set up between the neighboring two hollow pattern shell(-), the cast-in-place reinforced concrete top plate(-) is on the top of it(-), the three are poured into a whole, the hollow pattern shell(-) including the upper plate(-), the side wall(-) and the lower floor(-). The upper plate (-), the side wall(-), the lower floor(-) contact with each other and form a polyhedron closed cavity(-). The upper plate (-), the side wall(-) respectively coincide with cast-in-place reinforced concrete top plate(-), cast-in-place reinforced concrete rib(-), at least one pole(-) in the cavity(-). The character of that is the lower floor (-) has at least one reinforcing bar (-), from which there is link stretching out on the lower floor (-), linking with the pole (-). This is fit for the hollow concrete structures including house roof, base plate, and so on.

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 200510073675.X, 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 (s...

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.
