Description

Technical Field

[0001] This invention relates to a floor slab connection structure based on prefabricated buildings, belonging to the field of prefabricated building technology. Background Technology

[0002] Currently, in the construction of prefabricated buildings, floor slabs are connected to beams by bolts through pre-drilled holes in the floor slabs. The connection between floor slabs is also generally achieved by overlapping the joints in a stepped manner and then connecting them together with bolts. This results in a large workload, high cost, and long construction period during on-site construction. Furthermore, it is very inconvenient for workers to assemble the slabs, leading to low installation efficiency. Summary of the Invention

[0003] This invention overcomes the shortcomings of existing technologies and provides a floor slab connection structure based on prefabricated buildings. It reduces the amount of construction work, lowers construction costs and construction period, and makes assembly and operation convenient for workers with high installation efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a floor slab connection structure based on prefabricated buildings, including floor slabs and beams, wherein the floor slabs are laid sequentially on the beams, and the two ends of the floor slabs overlap the beams accordingly. Multiple first through holes are sequentially provided on both ends of the floor slabs located at the upper end of the beams. A first sleeve is provided in each of the first through holes. The first sleeves are fixed to the steel mesh of the floor slabs and cast together. A first stud is inserted into the sleeve. The end of the first stud near the beam is welded and fixed to the beam by a stud welding machine.

[0005] Both ends of the floor slab are provided with protruding overlapping plates, which are integrally cast with the floor slab. The upper surface of the overlapping plate on one side of the floor slab is flush with the upper surface of the floor slab, and the lower surface of the overlapping plate on the other side of the floor slab is flush with the lower surface of the floor slab. Adjacent floor slabs are joined together by matching and staggered overlapping plates. Each overlapping plate is provided with a plurality of second through holes, and the positions of the second through holes on the overlapping plates flush with the upper surface of the floor slab and the overlapping plates flush with the lower surface of the floor slab correspond to each other. Each second through hole is provided with a second sleeve, which is connected to the floor slab. A first supporting steel plate is horizontally installed in the second through hole of the overlapping plate with the lower plane. The first supporting steel plate is integrally cast with the overlapping plate and the floor slab, and the first supporting steel plate completely seals the corresponding second through hole. The bottom of the second sleeve on the lower overlapping plate is welded or directly pressed onto the first supporting steel plate, that is, the second sleeve on the lower overlapping plate is shorter than the second sleeve on the upper overlapping plate. A second stud is installed in the two corresponding second through holes. The second stud is welded and fixed to the first supporting steel plate by a stud welding machine, connecting and fixing the two adjacent floor slabs together.

[0006] Furthermore, filler is used to fill the space between the first stud and the first sleeve, and between the second stud and the second sleeve, so that the floor slab connection is flat overall.

[0007] Furthermore, the connection structure between adjacent floor slabs is replaced by the following structure: a splicing cavity is provided at the joint between adjacent floor slabs, and the splicing cavity is filled with a filler, which connects all floor slabs into a whole.

[0008] Furthermore, both ends of the floor slab are provided with flared trapezoidal groove structures. The trapezoidal groove structures are arranged longitudinally along the floor slab. The upper and lower end faces of the trapezoidal groove structures are staggered, and the upper end face of the trapezoidal groove structures is recessed inward, so that two adjacent floor slabs cooperate to form a cavity structure with a gap on the upper side.

[0009] Furthermore, the upper and lower ends of the outer sides of the first sleeve and the second sleeve are provided with hoops, which are fitted onto the first sleeve or the second sleeve in a matching manner, and the ends of the hoops are welded to the reinforcing mesh.

[0010] Furthermore, the lower parts of the first sleeve and the second sleeve are fixed by a second support steel plate with through holes to replace the sleeve clamp, and the upper side of the second support steel plate is welded and fixed to the reinforcing mesh.

[0011] The advantages of this invention compared to existing technologies are as follows: After the floor slabs are laid, studs are sequentially welded to the steel structure beams using a stud welding machine, eliminating the need to drill screw holes in the beams. The floor slabs are joined together to form a hollow columnar structure, which facilitates the filling of cement mortar. The two ends of the floor slabs are designed as trapezoidal grooves, creating a tenon-and-mortise structure between two adjacent floor slabs after filling with cement mortar. Alternatively, the floor slabs can be designed as overlapping structures, and then the two overlapping floor slabs are welded together using studs and the joints are filled with cement mortar. The entire construction process is simple and efficient, greatly shortening the construction period, reducing costs, decreasing the workload of workers, and significantly improving installation efficiency.

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments.

[0019] like Figures 1-4 As shown, this invention discloses a floor slab connection structure based on prefabricated buildings, including a floor slab 1 and a beam 2. The floor slab 1 is laid on the beam 2 in sequence, and the two ends of the floor slab 1 are correspondingly connected to the beam 2. Multiple first through holes 3 are sequentially provided on both ends of the floor slab 1 located at the upper end of the beam 2. A first sleeve 4 is provided in each of the first through holes 3. The first sleeve 4 is fixed and cast together with the steel mesh 6 of the floor slab 1. A first stud 5 is inserted into the sleeve 4. The end of the first stud 5 near the beam 2 is welded and fixed to the beam 2 by a stud welding machine.

[0020] Both ends of the floor slab 1 are provided with protruding overlapping plates 7, which are integrally cast with the floor slab 1. The upper surface of the overlapping plate 7 on one side of the floor slab 1 is flush with the upper surface of the floor slab 1, and the lower surface of the overlapping plate 7 on the other side of the floor slab 1 is flush with the lower surface of the floor slab 1. Adjacent floor slabs 1 are joined together by matching and staggered overlapping plates 7. Each overlapping plate 7 is provided with a plurality of second through holes 8, and the positions of the second through holes 8 on the overlapping plate 7 flush with the upper surface of the floor slab 1 and the overlapping plate 7 flush with the lower surface of the floor slab 1 correspond to each other. Each second through hole 8 is provided with a second sleeve 9, which is connected to the lower surface of the floor slab 1. A first supporting steel plate 10 is horizontally installed in the second through hole 8 on the flush overlapping plate 7. The first supporting steel plate 10 is integrally cast with the overlapping plate 7 and the floor slab 1, and the first supporting steel plate 10 completely blocks the corresponding second through hole 8. The bottom of the second sleeve 9 on the lower overlapping plate 7 is welded or directly pressed onto the first supporting steel plate 10, that is, the second sleeve 9 on the lower overlapping plate 7 is shorter than the second sleeve 9 on the upper overlapping plate 7. A second stud 11 is installed in the two corresponding second through holes 8. The second stud 11 is welded and fixed to the first supporting steel plate 10 by a stud welding machine, connecting and fixing the two adjacent floor slabs 1 together.

[0021] The space between the first stud 5 and the first sleeve 4, and between the second stud 11 and the second sleeve 9, is filled with filler 13, so that the connection of the floor slab 1 is flat.

[0022] The connection structure between adjacent floor slabs 1 is replaced by the following structure: a splicing cavity 12 is provided at the splicing point between adjacent floor slabs 1, and the splicing cavity 12 is filled with a filler 13, which connects all floor slabs 1 into a whole.

[0023] Both ends of the floor slab 1 are provided with flared trapezoidal groove structures 14. The trapezoidal groove structures 14 are arranged longitudinally along the floor slab 1. The upper and lower end faces of the trapezoidal groove structures 14 are staggered, and the upper end face of the trapezoidal groove structures 14 is recessed inward, so that two adjacent floor slabs 1 cooperate to form a cavity structure with a gap on the upper side.

[0024] Both the upper and lower ends of the first sleeve 4 and the second sleeve 9 are provided with a collar 15, which is fitted onto the first sleeve 4 or the second sleeve 9 in a matching manner, and the end of the collar 15 is welded to the steel mesh 6.

[0025] The lower parts of the first sleeve 4 and the second sleeve 9 are fitted and fixed with a second support steel plate 16 with through holes to replace the sleeve 15. The upper side of the second support steel plate 16 is welded and fixed to the steel mesh 6.

[0026] This invention involves welding studs sequentially onto steel structural beams after the floor slabs are laid, eliminating the need for drilling screw holes in the beams. Floor slabs are joined together, either by connecting cavities, to form a hollow columnar structure, facilitating the filling of cement mortar. Trapezoidal grooves are created at both ends of the floor slabs, forming a tenon-and-mortise structure between adjacent slabs after cement mortar filling. Alternatively, floor slabs can be joined in an overlapping manner, then welded together with studs and sealed with cement mortar. The entire construction process is simple and efficient, significantly shortening the construction period, reducing costs, minimizing labor, and greatly improving installation efficiency.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
