DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0021] REFERENCE Figures 1-5 A fabricated concrete laminated floor slab connecting structure, comprising a laminated slab 1, a plurality of threaded grooves 2 are formed around the laminated slab 1, which are used for positioning and connecting between two laminated slabs 1. By inserting bolts or screws into the corresponding threaded grooves 2, two laminated slabs 1 can be fastened together. The upper surface of the laminated slab 1 is provided with a fixed groove 6, and the lower surface of the laminated slab 1 is provided with a T-shaped block 45 matched with the fixed groove 6. When connected, the T-shaped block 45 of the upper laminated slab 1 will be clamped into the space formed by the L-shaped block 44 inside the fixed groove 6 of the lower laminated slab 1 to realize the fixation in the vertical direction.

[0022] In this embodiment, the two sides of the laminated slab 1 are fixed with U-shaped sliding plates 3, and the long plate 42 is slidingly arranged in the U-shaped sliding plate 3. The notch 43 is formed on the long plate 42, which is used to adjust the position of the long plate 42, so as to realize the position adjustment of the long plate 42 in the horizontal direction.

[0023] In this embodiment, the fixed groove 6 is provided with a connecting device 4, which comprises a long rod 41 penetrating through the fixed groove 6 and sliding in the fixed groove 6. One end of the long rod 41 is fixedly connected with the long plate 42, and the other end of the long rod 41 is fixedly connected with the L-shaped block 44. In the fixed groove 6, the spring 46 is arranged between the L-shaped block 44 and the long plate 42. The spring 46 drives the L-shaped block 44 to reset through the elastic force of itself, so as to ensure the stable and reliable connection.

[0024] In this embodiment, the L-shaped block 44 is located on the movement track of the T-shaped block 45, the bottom of the L-shaped block 44 is in contact with the top of the fixed groove 6, and the two L-shaped blocks 44 simultaneously clamp and fix the T-shaped block 45, so as to realize the fixation of the upper and lower laminated slabs 1.

[0025] In this embodiment, the inner wall of the fixed groove 6 is provided with a sealing device 5, which comprises a fixed block 51 fixedly connected to the inner wall of the fixed groove 6, and an elastic arc block 52 fixedly connected to the top of the fixed block 51. A sealing gasket 53 is arranged below the opening of the fixed groove 6 and above the L-shaped block 44, and surrounds the opening of the fixed groove 6. When the two laminated boards 1 are in contact, the T-shaped block 45 of the upper laminated board 1 will extrude the sealing gasket 53 on the inner wall of the fixed groove 6 of the lower laminated board 1. At this time, the elastic arc block 52 will extrude the sealing gasket 53 by its own elastic force, thereby increasing the sealing between the two laminated boards 1. The sealing gasket 53 not only makes the connection more compact and smooth, but also helps to improve the appearance of the structure, and balances the fixed block 51 to prevent displacement of the laminated board 1 due to left and right vibration in the later use process.

[0026] Specifically, when the two laminated boards 1 are in contact, the upper laminated board 1 will extrude the sealing gasket 53 on the inner wall of the fixed groove 6 of the lower laminated board 1. The sealing gasket 53 is extruded and extruded to the elastic arc block 52. When the two laminated boards 1 are placed, the elastic arc block 52 will extrude the sealing gasket 53 by its own elastic force, thereby increasing the sealing of the two laminated boards 1. The sealing gasket 53 can make the connection more compact and smooth, and help to improve the appearance of the structure.

[0027] The working principle of the utility model is:

[0028] In use, the threaded grooves 2 of the two laminated boards 1 to be assembled are aligned with each other, then the long plates 42 on both sides of the lower laminated board 1 are pulled through the notches 43, the two long plates 42 are moved under the action of the pulling force, the movement of the long plates 42 drives the movement of the long rods 41, the movement of the long rods 41 drives the movement of the L-shaped blocks 44 in the inner wall of the fixed groove 6, and the movement of the L-shaped blocks 44 also extrudes the springs 46, then the T-shaped block 45 arranged at the bottom of the upper laminated board 1 is clamped into the fixed groove 6 of the lower laminated board 1, then the two long plates 42 are loosened, the two springs 46 drive the respective L-shaped blocks 44 to reset by their own elastic force, and the two L-shaped blocks 44 simultaneously fix the T-shaped block 45, thereby achieving the effect of fixing the upper and lower laminated boards 1, effectively enhancing the strength and stability of the overall structure.

[0029] Finally, it should be pointed out that those skilled in the art can modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for part of the technical features. Any modification, equivalent substitution, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
