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, thereby causes dead load to increase.In order effectively to alleviate floor deadweight, adopt the mode of cassette ceiling more.
At present conventional cassette ceiling, 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, Chinese patent a kind of self-supporting thermal-insulation hollow floor slab is disclosed, 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 Structural Tectonics complexity that existing cassette ceiling exists, the loaded down with trivial details and floor slab structure rigidity of constructing not to etc. defect, it is a kind of in the situation that ensureing floor slab structure rigidity that the utility model provides, can effectively alleviate floor deadweight, improve the steel bar truss floor support plate cassette ceiling of floor sound insulation property simultaneously.
The technical solution adopted in the utility model is:
Steel bar truss floor support plate cassette ceiling, comprise multiple frameworks that formed with the multiple steel bar girders that are erected at template top and be connected with described template by template, described template is connected by connector with described steel bar girder, described steel bar girder upper has concrete, it is characterized in that: between the steel bar girder described in adjacent two, be provided with lightweight spheroid.
Further, described lightweight spheroid is fixedly mounted between two adjacent steel bar girders by fastening devices, described fastening devices comprises upper reinforcement and lower rebar, the top of described lightweight spheroid is connected with described upper reinforcement, the bottom of described lightweight spheroid is connected with described lower rebar, and described upper reinforcement is connected with contiguous steel bar girder respectively with lower rebar.
Further, the described lightweight spheroid quantity between the steel bar girder described in two of arbitrary neighborhoods is identical, and spaced set.
Further, described lightweight spheroid can be the spheroid of foam ball, hollow ball or other light materials composition.
A kind of construction method of steel bar truss floor support plate cassette ceiling described above, described type steel bar truss cassette ceiling comprises multiple frameworks that are made up of with the multiple steel bar girders that are erected at template top and be connected with described template template, described template is connected by connector with described steel bar girder, described steel bar girder upper has concrete, it is characterized in that: described construction method comprises:
(1), be ready to steel bar girder, template, connector, lightweight spheroid, fastening devices spare and accessory parts;
(2), the framework of the hollow floor support plate of assembling type steel bar truss, first steel bar girder and template are assembled together by connector, or factory becomes floor support plate by template with steel bar truss welding, then by fastening devices, lightweight spheroid is equidistantly fixed between adjacent two steel bar girders;
(3), the hollow floor support plate framework assembling is routed on floor;
(4), between two hollow floor support plate frameworks, fix lightweight spheroid by fastening devices;
(5), other additional bars of colligation, lay floor gut line, the hole in reserved floor;
(6), to described framework concreting;
(7), concrete strength reaches after requirement, removes connector and template, or tears the template of welding, forms the hollow floor support plate of type steel bar truss.
When the utility model concreting, lightweight spheroid is non-rising, do not move, and concrete reaches after the intensity of form removal requirement, template and connector is removed and can be reused, or tear the template of welding, finally forms cassette ceiling.After form removable, soffit planeness is good, does not need to plaster.
The beneficial effects of the utility model are embodied in: steel bar truss floor support plate cassette ceiling of the present utility model, and all component and fitting batch production processing, mating formation in scene, when construction, can bear concrete gravity and working load.Speed of application is fast, and Forming Quality is good, effectively alleviates floor deadweight, saves material usage, improves rigidity and the sound insulation property of floor simultaneously.

Detailed description of the invention
Referring to figs. 1 through Fig. 6, steel bar truss floor support plate cassette ceiling, comprise multiple frameworks that formed with the multiple steel bar girders 2 that are erected at template 1 top and be connected with described template 1 by template 1, described template 1 is connected by connector 3 is detachable with described steel bar girder 2, or in factory, described template 1 and described steel bar girder 2 is welded together.Described steel bar girder 2 uppers have concrete, between the steel bar girder 2 described in adjacent two, are provided with lightweight spheroid 4.
Further, described lightweight spheroid 4 is fixedly mounted between two adjacent steel bar girders 2 by fastening devices 5, described fastening devices 5 comprises upper reinforcement 51 and lower rebar 52, the top of described lightweight spheroid 4 is connected with described upper reinforcement 51, the bottom of described lightweight spheroid 4 is connected with described lower rebar 52, and described upper reinforcement 51 is connected with contiguous steel bar girder 2 respectively with lower rebar 52.
Further, described lightweight spheroid 4 quantity between the steel bar girder 2 described in two of arbitrary neighborhoods are identical, and spaced set.
Further, described lightweight spheroid 4 can be the spheroid of foam ball, hollow ball or other light materials composition.
When the utility model concreting, lightweight spheroid is non-rising, do not move, and concrete reaches after the intensity of form removal requirement, template and connector is removed and can be reused, or tear the template of welding, finally forms cassette ceiling.After form removable, soffit planeness is good, does not need to plaster.
