Abstract
The utility model discloses an one -way composite floor slab of die mould steel plate concrete of built -in hollow square steel pipe, including profiled sheet, hollow square steel pipe, the profiled sheet is laid on the girder steel, and the recess of profiled sheet is parallel with the short direction of striding of one -way composite floor slab, the hollow square steel pipe arrange in the profiled sheet the groove and not with recess bottom contact, set up the reinforcing bar in hollow square steel pipe top, support the one -way composite floor slab of template concreting formation in the side of profiled sheet. The utility model discloses built -in hollow square steel pipe bearing capacity is big, and under the condition of the same bearing capacity, more ordinary floor weight is lighter, thickness is littleer, has improved floor clear height, reduces the cost, can use in the one -way slabs structure of big space, large -span, big load.
Description
Technical field
The utility model belongs to building structure technology field, particularly the unidirectional combination floor of die mould steel plate concrete of a kind of built-in Hollow Square Steel pipe.
Background technology
Currently, China's industry with in covil construction, skeleton construction because of starting material extensive, technology maturation, cheap is still the architecture structure form being most widely used. But along with the raising that building height and antidetonation require, and modern architecture is high to layer, the requirement of large span, large space is more and more higher, makes the application of skeleton construction obtain more restriction. In recent years, the development of reinforced concrete composite structure brings many superiority, and in unitized construction, more and more employing composite deck slabs is as floor framing system.
But 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, Zhi Mo, form removal construction trouble and long construction period need to be carried out, having beam plate often can not meet the requirement of buildings clear height and add layer high, chainless drives poor seismic behavior easily produces degree of disturbing, crack. (2) composite deck slabs: large span composite deck slabs plate thick too thick while from great, die mould steel plate and concrete viscosifying power are poor, 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 is that vertical equity shear bond destroys, lacking enough viscosifying power will make profiled steel sheet combination floor lose compound action.
Practical novel content
The purpose of this utility model is to provide that a kind of supporting capacity height, deadweight are light, the unidirectional combination floor of die mould steel plate concrete of the built-in Hollow Square Steel pipe of easy construction.
The technical solution realizing the utility model object is: the unidirectional combination floor of die mould steel plate concrete of a kind of built-in Hollow Square Steel pipe, comprise die mould steel plate, Hollow Square Steel pipe, die mould steel plate is laid on girder steel, the groove of die mould steel plate is short parallel across direction with unidirectional combination floor, Hollow Square Steel pipe is placed in the groove place of die mould steel plate and does not contact with bottom portion of groove, arranging reinforcing bar above Hollow Square Steel pipe, the lateral support template casting concrete at die mould steel plate forms unidirectional combination floor.
The utility model is compared with prior art, its remarkable advantage: (1) built-in Hollow Square Steel pipe bearing capacity is big, when same bearer power, more common floor weight is lighter, thickness is less, improve floor clear height, reduce cost, can be applicable in the one-way slabs structure of large space, large span, big load. (2) Hollow Square Steel pipe is linked to be an entirety by gusseted and the die mould steel plate being welded to connect, add steel and concrete contact surface, it is to increase the cohesive force of concrete and compoboard. (3) Hollow Square Steel pipe, die mould steel plate can source mill prefabricated, quality is easy to be ensured, construction machinery rate height; (4) during construction, die mould steel plate serves as bottom template from load-bearing, easy construction, shortens the duration, saves template.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the unidirectional combination floor of the utility model.
Fig. 2 is sectional view of the present utility model.
Embodiment
Composition graphs 1 and Fig. 2, the unidirectional combination floor of die mould steel plate concrete of the utility model built-in Hollow Square Steel pipe, comprise die mould steel plate 2, Hollow Square Steel pipe 3, die mould steel plate 2 is laid on girder steel, the groove 7 of die mould steel plate 2 is short parallel across direction with unidirectional combination floor, Hollow Square Steel pipe 3 be placed in die mould steel plate 2 groove 7 place and not with groove 7 base contact, reinforcing bar 5 is set above Hollow Square Steel pipe 3, the lateral support template casting concrete 1 at die mould steel plate 2 forms unidirectional combination floor.
Described reinforcing bar 5 can be individual layer and bidirectional arrangements in length and breadth. Reinforcing bar 5 arranges concrete cover.
Described gusseted 4 one end is welded with Hollow Square Steel pipe 3, and the other end welds with the rib top 8 of die mould steel plate 2, and Hollow Square Steel pipe 3 is supported unsettled in the groove 7 of die mould steel plate 2 by spaced apart multiple gusseted 4 as required.
Embodiment
First die mould steel plate 2 is laid on girder steel (die mould steel plate is placed in the lowest layer) by the utility model in construction process, the groove 7 of die mould steel plate is short parallel across direction with unidirectional combination floor, is fixed on girder steel by die mould steel plate 2 and realizes serving as, from load-bearing, the effect that bottom template also plays plate bottom principal rod simultaneously. Then Hollow Square Steel pipe 3 is placed in die mould steel plate 2 groove 7 place and distance groove 7 bottom certain distance, the gusseted 4 simultaneously arranged with interval welding supports Hollow Square Steel pipe 3 thus makes Hollow Square Steel pipe 3 unsettled in the groove 7 of die mould steel plate, gusseted 4 one end is welded with Hollow Square Steel pipe 3, and the other end welds with die mould steel plate rib top 8 and forms weld seam 6. Then arrange single-layer bidirectional reinforcing bar 5 on the top of Hollow Square Steel pipe 3 and stay suitable concrete cover, finally prop up Side shuttering casting concrete 1.
