[0020] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-5 The present invention provides a technical solution: a tool for reinforcing composite slabs, comprising two composite slab bodies 1, an upper reinforcing plate 2 movably disposed above the two composite slab bodies 1, a lower reinforcing plate 3 disposed below the two composite slab bodies 1, and two reinforcing components 4 disposed between the upper reinforcing plate 2 and the lower reinforcing plate 3. The reinforcing components 4 include a rectangular plate 401, a threaded rod 402, a connecting rod 403, a limiting block 404, an internal threaded cylinder 405, a PVC pipe 406, a connecting block 407, and a bearing 408.

[0022] A threaded rod 402 is fixedly installed on the lower surface of the upper reinforcing plate 2. A PVC pipe 406 is movably sleeved on the outer side of the threaded rod 402. The top end of the PVC pipe 406 is fixedly connected to the lower surface of the upper reinforcing plate 2. A rectangular plate 401 is fixedly installed on the lower surface of the lower reinforcing plate 3. Two connecting rods 403 are fixedly installed on the lower surface of the rectangular plate 401. A limit block 404 is fixedly installed at the bottom end of the connecting rod 403. The bottom end of the threaded rod 402 extends to the bottom of the lower reinforcing plate 3. Between the two connecting rods 403, the outer side of the threaded rod 402 is threadedly connected to the inner threaded cylinder 405. The outer side of the two connecting rods 403 is movably fitted with a connecting block 407. The inner threaded cylinder 405 is rotatably installed between the two connecting blocks 407 through the bearing 408. By the cooperation between the threaded rod 402 and the inner threaded cylinder 405, the connection between the upper reinforcing plate 2 and the lower reinforcing plate 3 is quickly realized. Under the action of the bearing 408 and the connecting block 407, the inner threaded cylinder 405 is limited.

[0023] The upper surface of the rectangular plate 401 is provided with a first through hole 7, the inner wall of the first through hole 7 is in movable contact with the outer side of the threaded rod 402, and the upper surface of the lower reinforcing plate 3 is provided with a second through hole 8, the inner wall of the second through hole 8 is in movable contact with the outer side of the threaded rod 402, and the threaded rod 402 extends to the bottom of the lower reinforcing plate 3 through the first through hole 7 and the second through hole 8.

[0024] A circular hole 6 is provided on the upper surface of the connecting block 407. The inner wall of the circular hole 6 is in contact with the outer side of the connecting rod 403. The circular hole 6 allows the connecting block 403 to slide on the outer side of the connecting rod 407.

[0025] A bearing 408 is fixedly connected between the two connecting blocks 407. The inner wall of the bearing 408 is fixedly connected to the outer side of the internal threaded cylinder 405. The internal threaded cylinder 405 is rotatably installed between the two connecting blocks 407 through the bearing 408.

[0026] A rubber gasket 5 is fixedly bonded to the lower surface of the upper reinforcing plate 2. A through hole 9 is opened on the lower surface of the rubber gasket 5. The inner wall of the through hole 9 is fixedly connected to the outer side of the PVC pipe 406. The upper surface of the composite plate 1 is protected by the rubber gasket 5.

[0027] When this utility model is in operation: To reinforce two stacked plate bodies 1, an upper reinforcing plate 2, and a lower reinforcing plate 3, the upper reinforcing plate 2 is placed on the upper surface of the two stacked plate bodies 1, with the lower surface of the rubber gasket 5 contacting the upper surface of the two stacked plate bodies 1. The lower reinforcing plate 3 is then placed on the lower surface of the stacked plate body 1, and the threaded rod 402 passes sequentially through the first through hole 7 and the second through hole 8 until the bottom end of the PVC pipe 406 contacts the upper surface of the lower reinforcing plate 3. At this point, the internal threaded cylinder 405 is pushed upwards, causing the bearing 408 and the two connecting blocks 407 to move along the connecting... The rod 403 slides upward until the internal threaded cylinder 405 contacts the threaded rod 402. Then the internal threaded cylinder 405 is rotated so that the internal threaded cylinder 405 and the threaded rod 402 are threadedly engaged. While the internal threaded cylinder 405 is rotating, the bearing 408 and the two connecting blocks 407 slide upward on the outside of the connecting rod 403 until the upper surface of the internal threaded cylinder 405 contacts the lower surface of the lower reinforcing plate 3. This achieves reinforcement between the two composite plate bodies 1, the upper reinforcing plate 2 and the lower reinforcing plate 3. Concrete can then be poured between the two composite plate bodies 1 to complete the reinforcement between the two composite plate bodies 1 and the plate strip.

[0028] When it is necessary to remove the upper reinforcing plate 2 and the lower reinforcing plate 3 from the outside of the two composite plate bodies 1, rotate the internal threaded cylinder 405 so that the internal threaded cylinder 405 rotates inside the bearing 408. The rotation of the internal threaded cylinder 405 drives the bearing 408 and the two connecting blocks 407 to slide downward along the connecting rod 403 until the internal threaded cylinder 405 is completely separated from the threaded rod 402. At this time, the internal threaded cylinder 405 is connected between the two connecting blocks 407 through the bearing 408. Then, pull the upper reinforcing plate 2 upward. The upper reinforcing plate 2 drives the rubber gasket 5, the threaded rod 402 and the PVC pipe 406 to move upward, so that the upper reinforcing plate 2 and the lower reinforcing plate 3 can be separated. This makes it easy to quickly reinforce and remove the upper reinforcing plate 2 and the lower reinforcing plate 3 by cooperating with the threaded cylinder 405 and the threaded rod 402. After removal, the bearing 408 and the two connecting blocks 407 limit the position of the internal threaded cylinder 405, effectively preventing the internal threaded cylinder 405 from being lost.
