Reinforced concrete stereo load-carrying structure floor

Abstract

This invention discloses a steel bar stereo load-carrying structure floor. It includes cast-in-place concrete board, cast-in-place concrete rib, cavity moulding shell and space arrangement of cavity moulding shell with cast-in-place concrete rib in it, cast-in-place-concrete board is above it, and the three pieces is placing as one body. The cavity moulding shell includes up roof plate, around lateral wall and down plate, and they are connected with each other to form polyhedron sealing cavity, up roof plate and around lateral wall are congruented with cast-in-place-concrete up board and with cast-in-place concrete rib in it rib. At least one bar piece is set in cavity, the feature is that the integer is consisted by at least two bar pieces to form integer bar pieces group. It is propitious to house cover, base bottom board, wall body, bridge and other hollow structures.

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.
