Abstract
The invention discloses a bidirectional profiled steel sheet and concrete composite floor slab internally provided with hollow circular steel pipes. The bidirectional profiled steel sheet and concrete composite floor slab internally provided with the hollow circular steel pipes comprises a profiled steel sheet, the hollow circular steel pipes and a truss type reinforcement mesh. The profiled steel sheet is fixed to steel beams to serve as a lower formwork and a lower carrying bar. The hollow circular steel pipes are arranged in grooves and rib tops of the profiled steel sheet and the upper portions of the grooves. Every two hollow circular steel pipes are connected in a welded mode through steel bars so as to form the truss type reinforcement mesh and be fixed into a whole. Upper plate distribution steel bars are arranged in the direction perpendicular to the hollow circular steel pipes at intervals. The bidirectional composite floor slab is formed by supporting the formwork on the side face of the profiled steel sheet and pouring concrete. According to the bidirectional profiled steel sheet and concrete composite floor slab internally provided with the hollow circular steel pipes, the bearing capacity of the internal hollow circular steel pipes is high, the weight is lower, the thickness is smaller, the clear height of a storey is increased, and the construction cost is reduced; through the truss type steel bars, the shear resistance and bearing capacity of the oblique section of the floor slab are improved, and meanwhile the integrity of the composite floor slab and the binding force between the profile steel sheet and concrete are improved; and the bidirectional profiled steel sheet and concrete composite floor slab is particularly suitable for serving as large-span and large-load bidirectional slabs.
Description
Technical field
The invention belongs to technical field of buildings, particularly the profiled sheet concrete bidirectional composite floor of a kind of built-in open circles steel pipe.
Background technology
Currently, in China's industry with civil buildings, reinforced concrete structure is extensive because of raw material, technology maturation, cheap is still the architecture structure form being most widely used. But along with the raising of building height and shockproof requirements, and modern architecture to floor height, large span, large space requirement more and more higher, make the application of reinforced concrete structure obtain more restriction. In recent years, the development of reinforced concrete composite structure brings many superioritys, and in combinative structure, more and more employing composite deck slabs are as floor framing system. Composite deck slabs can by its each building block location and feature, give full play to steel tension and the good advantage of concrete anti-compression performance, and there is good anti-seismic performance, workability, the technology of composite deck slabs obtains rapid development. Especially the issuing and implementation of " composite floor design and construction specification " (CECS273:2010) have promoted the development of composite deck slabs significantly.
Traditional reinforced concrete floor and composite deck slabs system all also exist following technical problems: (1) in-situ reinforced concrete slab: conduct oneself with dignity too big, it is easily generated degree of disturbing, crack, formwork, form removal construction trouble and long construction period need to be carried out, having beam slab tend not to meet the requirement of building clear height and add floor height, chainless drives poor seismic behavior is easily generated degree of disturbing, crack. if particularly large-span floor adopts above-mentioned form floor and designs according to existing " reinforced concrete structural design specification " that will to face thickness of slab too thick, excessive and the requirement that is difficult to meet crack problem of conducting oneself with dignity. (2) composite deck slabs: from great while that large span composite deck slabs thickness of slab being too thick, profiled sheet is poor with concrete cementitiousness, such as document 1 (Zhang Xinying, Shi Qingxuan: cross section profiled steel sheet combination floor longitudinal shear bond bearing capacity research of remaining silent, " research of Sichuan architecture science " 2012, 38 (02): 52-54) one of damage-form that profiled steel sheet combination floor is main by verification experimental verification destroys for vertical equity shear bond, lacking enough cementitiousness will make profiled steel sheet combination floor lose compound action.
Summary of the invention
It is an object of the invention to provide a kind of bearing capacity height, from the profiled sheet concrete bidirectional composite floor of heavy and light, the built-in open circles steel pipe of easy construction.
The technical solution realizing the object of the invention is: the profiled sheet concrete bidirectional composite floor of a kind of built-in open circles steel pipe, including profiled sheet, open circles steel pipe and trussed reinforcing bar network, this profiled sheet is fixed on girder steel and serves as bottom template and plate bottom principal rod, groove at profiled sheet, open circles steel pipe is arranged on rib top and groove top, each open circles steel pipe is fixed by reinforcement welding connection formation trussed reinforcing bar network between two and is become an entirety, it is being perpendicular to installation plate top, interval, the direction distribution bar of open circles steel pipe, lateral support template casting concrete at profiled sheet forms bi-directional combination floor.
The present invention is compared with prior art, its remarkable advantage: (1) built-in open circles steel pipe bearing capacity is big, when same bearer power, more common composite deck slabs weight is lighter, thickness is thinner, improve floor clear height, reduce cost, truss-like reinforcing bar improves floor shear Capacity, also improve the globality of composite floor and profiled sheet and concrete cohesive force simultaneously, it is particularly suited in the two-way slab of the big load of large span, for instance gymnasium, large-scale exhibition center, railway station etc. (2) open circles steel pipe, profiled sheet can processing factory prefabricated, quality can be easily obtained guarantee, and construction machinery rate is high. (3) during construction, profiled sheet self-supporting serves as bottom template, easy construction, reduction of erection time, saves template.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
