Abstract
A novel floor slab connecting structure relates to an assembly type building structure. The prefabricated concrete beam comprises a prefabricated concrete beam and a cantilever plate which is fixedly connected to the top end of the prefabricated concrete beam. The key technology is that profiled steel plates are respectively fixed on two sides of a cantilever plate, and a beam slab concrete slab is cast on the cantilever plate between the profiled steel plates and on the top surface of the profiled steel plates in situ. The utility model has the advantages that: the intensity of make full use of profiled sheet replaces the template in the traditional roof beam slab concrete construction technique, does not need the formwork, has solved the higher large-scale industrial building of floor height or the difficult problem of public building formwork, reaches the saving cost for the purpose of construction progress, has guaranteed the beam slab wholeness simultaneously, makes the atress mode of roof beam the same with the roof beam atress mode that adopts traditional construction mode, guarantees the security of structure, also the structural design of being convenient for calculates.
Description
Technical Field
A novel floor slab connecting structure relates to an assembly type building structure.
Background
In recent years, with the increasing aging of China, the labor cost is higher and higher. In a traditional building construction mode, a template belongs to a low-value consumable product, and a large amount of manpower is consumed for on-site template support; government policies support fabricated buildings, and the requirements of fabricated buildings are more and more vigorous. With the popularization of the assembly type technology, the formwork of large-scale industrial buildings and public buildings with higher floor heights becomes a difficult problem.
Disclosure of Invention
The utility model discloses the problem that solves just provides one kind to more than not enough and need not a formwork, is applicable to the assembled building structure of the higher large-scale industrial building of floor height or public building. The technical scheme is as follows:
the utility model provides a novel floor connection structure, includes the precast concrete roof beam and connects the board of choosing of being fixed in precast concrete roof beam top. The key technology is that profiled steel plates are respectively fixed on two sides of a cantilever plate, and a beam slab concrete slab is cast on the cantilever plate between the profiled steel plates and on the top surface of the profiled steel plates in situ.
And an embedded part is arranged between the cantilever plate and the profiled steel sheet.
The thickness of the profiled steel sheet is 1.2-1.6 mm.
Compared with the prior art, the utility model discloses the beneficial effect who has is:
1. the intensity of make full use of profiled sheet replaces the template in the traditional roof beam slab concrete construction technique, does not need the formwork, has solved the higher large-scale industrial building of floor height or the difficult problem of public building formwork, reaches the saving cost for the purpose of construction progress, has guaranteed the beam slab wholeness simultaneously, makes the atress mode of roof beam the same with the roof beam atress mode that adopts traditional construction mode, guarantees the security of structure, also the structural design of being convenient for calculates.
2. In order to ensure the T-shaped stress mode of the beam, the profiled steel sheet is only supported on the cantilever plate, the plate and the upper part of the beam are integrally cast in situ, and meanwhile, the waterproofness of the beam-slab structure is also ensured.
3. While the edge of the profiled steel plate is welded with the embedded part on the cantilever plate, the stud is welded on the embedded part in a fusion mode, so that the profiled steel plate is prevented from moving in the construction process.
4. The utility model is suitable for a secondary beam distributes evenly, the little public building of secondary beam interval.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a usage state diagram of the present invention.
Detailed Description
Referring to fig. 1 and 2, the novel floor slab connection structure comprises a precast concrete beam 1 and a cantilever plate 2 connected and fixed to the top end of the precast concrete beam 1. The key technology is that profiled steel plates 4 are fixed on two sides of a cantilever plate 2 through studs 5 respectively to serve as templates, and a beam slab concrete slab 6 is cast on the cantilever plate 2 between the profiled steel plates 4 and on the local whole top surface of the profiled steel plate 4, so that the structural integrity is ensured, the beam stress is more reasonable, the beam slab seepage prevention is ensured, and the structure has good waterproof performance.
An embedded part 3 is arranged between the cantilever plate 2 and the profiled steel sheet 4.
The thickness of the profiled steel sheet 4 is 1.2-1.6 mm.
The profiled steel sheet 4 can adopt Q235 steel or Q345 steel, and the industrial building can adopt open profiled steel sheets, such as YX 75-200-600; the selection of the profiled steel sheet corresponding to the public building can select an open or closed profiled steel sheet according to the decoration specification.
The utility model provides a novel floor connection structure, its construction step is as follows:
1. analyzing a construction drawing, paying off and positioning according to the construction drawing, hoisting the precast concrete beam 1, and installing in place;
2. cutting the profiled steel sheet 4 according to the field condition to enable the length of the profiled steel sheet to be the beam clear span;
3. laying a profiled steel sheet 4;
4. welding studs 5, and welding two studs in each wave trough; the two profiled steel plates are welded by adopting a 6 mm high continuous welding line, so that the longitudinal integrity of the profiled steel plates is ensured; and the continuous welding seam welding is adopted at the joint of the profiled steel plate edge and the embedded part 3 to limit the movement of the profiled steel plate.
5. And (5) binding the floor slab reinforcing steel bars and the beam upper reinforcing steel bars, and pouring a beam slab concrete slab 6 to complete floor slab construction.
Claims (3)
