Description

Technical Field

[0001] This utility model relates to the technical field of floor slab connectors, specifically to a quick-positioning connector for combining cast-in-place concrete floor slabs and composite slabs. Background Technology

[0002] In the field of building construction, the integration of cast-in-place concrete floor slabs and composite slabs is a common and crucial step. In traditional construction processes, the spatial positioning of the floor slab and composite slab often lacks a precise and efficient connection structure. Construction workers mostly rely on experience or simple auxiliary tools when positioning these components, making it difficult to ensure accuracy and prone to positional deviations. This can lead to structural quality problems after subsequent concrete pouring, affecting the overall safety and stability of the building.

[0003] Due to the lack of an effective rapid positioning method, the positions of the main floor slab and the composite slab need to be repeatedly calibrated and adjusted during the positioning process. This not only consumes a lot of time and manpower, but also makes the on-site construction process loose and inefficient, seriously slowing down the overall project progress and increasing the construction cycle and cost. To address this issue, we propose a rapid positioning connector for combining cast-in-place concrete floor slabs and composite slabs. Utility Model Content

[0004] The purpose of this invention is to provide a quick-positioning connector for combining cast-in-place concrete floor slabs and composite slabs, in order to solve the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-positioning connector for combining cast-in-place concrete floor slabs and composite slabs, comprising a floor slab body and two composite slab bodies. The top outer wall of the floor slab body includes equidistantly distributed first extended reinforcing bars. One end of the top of each first extended reinforcing bar is fixed with an externally threaded fixing bar by welding. The side wall of the composite slab body includes equidistantly distributed second reinforcing bars. One end of each second reinforcing bar has a fan-shaped positioning block fixed with welding. The top of each externally threaded fixing bar has a positioning plate. An internally threaded hole is opened in the center of the positioning plate. The inner wall of the internally threaded hole is threadedly connected to the outer wall of the externally threaded fixing bar. The top outer wall of the positioning plate has four equidistantly distributed first positioning bars. The top outer wall of the positioning plate has two mutually symmetrical first positioning holes. The outer wall of the fan-shaped positioning block has three equidistantly distributed second positioning holes.

[0006] Preferably, the two composite slab bodies are respectively disposed on the top two sides of the floor slab body, the floor slab body maintains a vertical structure, and the two composite slab bodies maintain a horizontal structure.

[0007] Preferably, a positioning ring is inserted into the top of the external threaded fixing post, and four equally spaced third positioning holes are opened on the outer wall of the positioning ring. Two mutually symmetrical second positioning posts are fixedly welded to the bottom outer wall of the positioning ring.

[0008] Preferably, one end of each of the four first positioning pins passes through the second positioning hole and enters the inner wall of the third positioning hole.

[0009] Preferably, the two second positioning pins pass through the second positioning hole and enter the inner wall of the first positioning hole.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0011] By using a precise interlocking positioning structure, such as the external threaded fixing post and the positioning plate threaded together, the first positioning post and the third positioning hole, and the second positioning post and the first positioning hole, the spatial positioning of the main body of the floor slab and the main body of the composite slab can be completed quickly without repeated calibration and adjustment. This greatly shortens the positioning time, makes the on-site construction process more compact and efficient, and speeds up the overall project progress. Attached Figure Description

[0023] Example 1: Refer to the appendix of the instruction manual. Figure 1-6 A quick-positioning connector for combining cast-in-place concrete floor slabs and composite slabs includes a floor slab body 1 and two composite slab bodies 2. The floor slab body 1 is placed vertically in the predetermined construction position. The two composite slab bodies 2 are placed on the top two sides of the floor slab body 1 respectively and maintain a horizontal structure. The top outer wall of the floor slab body 1 is provided with first extended steel bars 3 distributed at equal intervals. One end of the top of the first extended steel bars 3 is fixed with an external threaded fixing column 4 by welding.

[0024] Example 2: Based on Example 1, the internal threaded hole 8 at the center of the positioning disk 7 is threadedly connected to the outer wall of the external threaded fixing post 4, so that the positioning disk 7 is fixed on the external threaded fixing post 4. The top outer wall of the positioning disk 7 has four equidistant first positioning posts 9 and two mutually symmetrical first positioning holes 10. The side wall of the composite plate body 2 is provided with equidistant second steel bars 6. One end of the outer wall of the second steel bar 6 is fixed with a fan-shaped positioning block 11 by welding. The outer wall of the fan-shaped positioning block 11 has three equidistant second positioning holes 12.

[0025] Example 3: Based on Example 1, the positioning ring 13 is inserted into the top of the external threaded fixing post 4. The outer wall of the positioning ring 13 has four equally spaced third positioning holes 14. The bottom wall of the positioning ring 13 has two mutually symmetrical second positioning posts 15 fixed by welding. During the assembly process, it is ensured that one end of the four first positioning posts 9 can accurately pass through the second positioning hole 12 on the fan-shaped positioning block 11 and enter the inner wall of the third positioning hole 14 of the positioning ring 13. At the same time, the two second positioning posts 15 can pass through the second positioning hole 12 on the fan-shaped positioning block 11 and enter the inner wall of the first positioning hole 10 of the positioning plate 7, so as to realize the rapid positioning connection between the floor slab body 1 and the composite slab body 2.

[0026] Working principle of this utility model: Refer to the appendix of the instruction manual. Figure 1-6 When this utility model is used, the floor slab body 1 remains vertical. The external threaded fixing column 4 fixed on the first extended steel bar column 3 on the top outer wall is threadedly connected to the positioning plate 7 through the internal threaded hole 8. The four first positioning columns 9 and two first positioning holes 10 on the positioning plate 7 together form a preliminary positioning reference structure.

[0027] The composite slab body 2 is placed on both sides of the top of the floor slab body 1 and kept horizontal. The fan-shaped positioning block 11 welded and fixed on the second steel column 6 on its side wall cooperates with the positioning plate 7 and the positioning ring 13. When the connection operation is performed, the positioning ring 13 is inserted into the top of the external threaded fixing column 4. At this time, the four first positioning columns 9 on the positioning plate 7 accurately pass through the second positioning hole 12 on the fan-shaped positioning block 11 and further enter the third positioning hole 14 of the positioning ring 13. At the same time, the two second positioning columns 15 at the bottom of the positioning ring 13 also pass through the second positioning hole 12 of the fan-shaped positioning block 11 and accurately insert into the first positioning hole 10 of the positioning plate 7. Through this multi-directional and precise positioning and cooperation method, the floor slab body 1 and the composite slab body 2 are quickly and accurately positioned and connected together.
