Slab-column structure hollow slap with mixed use of filling rod and filling box

Abstract

The invention relates to a slab-column structure hollow slap with mixed use of a filling rod and a filling box, and belongs to the field of general building constructions. The hollow slap comprises a column (1), a beam (2), a column side solid area (3), a beam side hollow area (4) and a central hollow area (5), and is characterized in that: a filling rod combined block (6) is arranged in the beamside hollow area (4); the orientation of the filling rod combined block (6) in the beam side hollow area (4) is accordant with the direction of the beam (2) which is adjacent to the filling rod combined block (6); the filling box (7) is arranged in the central hollow area (5); and the filling rod combined block (6) and the filling box (7) are positioned between an upper layer steel bar (8) and a lower layer steel bar (9) and are permanently embedded in concrete (10). A hollow floor provided by the invention is reasonably stressed along with a high hollow ratio, and the structure of the hollowfloor also has high reliability, earthquake resistance and cracking resistance, so the hollow floor has high economical efficiency and practicability.

Description

(1) Technical field [0001] The invention relates to a reinforced concrete hollow floor structure, in particular to a slab-column structure hollow slab mixed with filling rods and filling boxes, which belongs to the field of general building construction. (2) Background technology [0002] In the field of construction, with the increasing number of long-span concrete structures, more and more floor slabs adopt hollow-core floor structure technology. Sometimes in order to reduce the self-weight of the structure or enhance the thermal insulation, heat insulation, sound insulation, and shock absorption effects of concrete, it is necessary to place some lightweight filler materials inside the concrete. Replacing part of the concrete with lightweight filling materials will basically not affect the mechanical performance of the structure, but it can greatly reduce the self-weight of the structure. [0003] In the hollow floor structure, according to the different force modes, it c...

Problems solved by technology

In ZL200710123516.5, the filling rods arranged on the side of the hidden beam on the column are arranged along the beam, and the filling rods in the mid-span area are arranged in the direction of the long span. The belt is still filled with rods, without making the structure obtain the maximum hollow ratio

[0007] To sum up, among the existing technologies for hollow slabs in slab-column structures, there is no technology that can make full use of the advantages of filling rods and filling boxes, overcome their shortcomings, and form a hollow floor with a large hollow rate and reasonable stress. structure
