Abstract
The utility model discloses a steel bar truss hollow overlapped floor slab which comprises prefabricated layer concrete and a plurality of steel bar trusses poured on the prefabricated layer concrete. Base feet of the steel bar trusses are embedded in the prefabricated layer concrete, the tops of the steel bar trusses penetrate the prefabricated layer concrete, and the steel bar trusses and the prefabricated layer concrete form a steel bar truss concrete template. Overlapped layer concrete is poured above the prefabricated layer concrete, the tops of the steel bar trusses are embedded in the overlapped layer concrete, and a light ball body is fixedly arranged between every two adjacent steel bar trusses. Under the condition that the floor slab structure rigidity is ensured, the floor slab self weight can be effectively reduced, no template is required in construction, and sound insulation performance of the floor slab can be improved.
Description
Technical field
The present invention relates to the hollow laminated floor slab of a kind of steel bar girder, belong to building engineering field.
Background technology
Along with building is used improving constantly of functional requirement, the application of large span, large bay floor is more and more, and the performance requirement floors such as strengthening floor slab rigidity, sound insulation have larger thickness, causes dead load to increase.In order effectively to alleviate floor deadweight, adopt the mode of cassette ceiling more.
At present conventional hollow building cover, is in conjunction with conventional concrete construction technology, aspect template, improves, and has Structural Tectonics complexity, a shortcoming such as loaded down with trivial details of constructing.The patent No. is ZL201110257073.5, the Chinese patent that name is called " self-supporting thermal-insulation hollow floor slab and construction method thereof " discloses a kind of self-supporting thermal-insulation hollow floor slab, this structure adopts pipe or square tube to form cassette ceiling, has the not reciprocity shortcoming of floor both direction rigidity.
Summary of the invention
In order to overcome complex structure that existing cassette ceiling exists, the shortcoming loaded down with trivial details, rigidity is little etc. of constructing, the invention provides the hollow laminated floor slab of steel bar girder that a kind of rigidity is large, speed of application is fast.
The technical solution used in the present invention is:
The hollow laminated floor slab of steel bar girder, it is characterized in that: comprise preformed layer concrete and be cast in the multiple steel bar girders on preformed layer concrete, the footing of described steel bar girder is embedded in described preformed layer concrete, the top of described steel bar girder is through described preformed layer concrete, and described steel bar girder and preformed layer concrete form steel bar girder concrete blinding; Overlapping layers concrete is built in the concrete top of described preformed layer, and the top of described steel bar girder buries in described overlapping layers concrete; Between steel bar girder described in adjacent two, be installed with lightweight spheroid.
Further, the concrete thickness of described preformed layer is 40～50mm.
Further, described lightweight spheroid is fixedly mounted between adjacent steel bar girder by fastening devices, described fastening devices is reinforcing bar, the two ends of described reinforcing bar are installed in respectively on described steel bar girder, and the grasping part of space formation lightweight spheroid between described reinforcing bar and the described concrete upper surface of preformed layer.
Further, described lightweight spheroid spaced set.
Further, described lightweight spheroid can be the spheroid of foam ball, hollow ball or other light materials composition.In construction overlapping layers during Concrete, the concreting lightweight spheroid under load action that vibrates keeps original form, and compressive strain does not occur.
Further, on described steel bar girder, be provided with additional bar.
A kind of construction method that adopts the hollow laminated floor slab of steel bar girder described above, the hollow laminated floor slab of described steel bar girder comprises preformed layer concrete and is cast in the multiple steel bar girders on preformed layer concrete, the footing of described steel bar girder is embedded in described preformed layer concrete, the top of described steel bar girder is through described preformed layer concrete, and described steel bar girder and preformed layer concrete form steel bar girder concrete blinding; Overlapping layers concrete is built in the concrete top of described preformed layer, and the top of described steel bar girder buries in described overlapping layers concrete; Between steel bar girder described in adjacent two, be installed with lightweight spheroid, it is characterized in that: described construction method comprises:
(1), steel bar girder completes standard component by factory and produces, and sends to erecting yard;
(2), scene first places steel bar girder location, builds preformed layer concrete, forms steel bar girder concrete blinding;
(3), preformed layer concrete reaches after intensity, by fastening devices, lightweight spheroid is equidistantly fixedly mounted between two steel bar girders;
(4), the above-mentioned steel bar girder concrete blinding that is equipped with lightweight spheroid is routed on floor;
(5), again between two adjacent steel bar girder concrete blindings, fix lightweight spheroid by fastening devices;
(6), colligation additional bar, lay floor gut line, the hole in reserved floor;
(7), build again overlapping layers concrete part;
(8), overlapping layers concrete strength reaches after requirement, forms the hollow laminated floor slab of steel bar girder.
The hollow laminated floor slab of steel bar girder of the present invention is that the steel bar stress in floor is welded into steel bar girder in factory, and scene places steel bar girder location, builds preformed layer concrete, is applicable to two-way slab.Preformed layer concrete reaches after intensity, forms steel bar girder concrete blinding, then fixes lightweight spheroid.Steel bar girder concrete blinding is routed on floor, then after water overlapping layers concrete and form steel bar girder hollow laminated floor slab.After the steel bar girder concrete blinding being made up of steel bar girder and preformed layer concrete can bear, water the concrete deadweight of overlapping layers and working load, do not need to set up again template.The hollow laminated floor slab of steel bar girder has that rigidity is large, speed of application is fast, at the bottom of plate Forming Quality good, do not need the advantages such as template, in engineering, be well used.
Beneficial effect of the present invention is embodied in: speed of application is fast, and Forming Quality is good, effectively alleviates floor deadweight, does not need template, saves material usage, improves rigidity and the sound insulation property of floor simultaneously.
