[0019] Embodiment: As Figures 1-4 shown, the present invention provides a technical solution: a connecting mechanism between a composite floor slab and a steel beam, including a steel beam body 1 and a floor slab body 2. Symmetrically and fixedly connected to both side ends of the steel beam body 1 and near the center are bearing plates 3. Slidably connected to the top of the bearing plate 3 is an installation plate 31. Slidably connected to the top of the installation plate 31 are a number of U-shaped blocks 32. Threadedly rotatably connected to the inner top of the U-shaped block 32 is a limit nut 33. Symmetrically and fixedly connected to both side ends of the steel beam body 1 and near both sides are two groups of first support plates 11. Fixedly connected between the side ends of the two first support plates 11 is a connecting block 13. Fixedly connected to the top of the first support plate 11 and on the side away from the steel beam body 1 is a hook 12. Fixedly connected to the bottom end of the floor slab body 2 and near the corners are connecting rings 22, and the connecting rings 22 and the hooks 12 are at the same horizontal level.

[0020] A slot 14 is opened at the center of the top end of the steel beam body 1.

[0021] By adopting the above technical solution, opening the slot 14 at the center of the top end of the steel beam body 1 is to cooperate with the insertion plate 21 to limit the floor slab body 2.

[0022] Fixedly connected to the center of the bottom end of the floor slab body 2 is an insertion plate 21, and the insertion plate 21 is adapted to the slot 14.

[0023] By adopting the above technical solution, setting the insertion plate 21 at the center of the bottom end of the floor slab body 2 is to insert it into the slot 14 to limit the floor slab body 2.

[0024] A chute 35 is opened at the center of the bearing plate 3.

[0025] By adopting the above technical solution, opening the chute 35 at the center of the bearing plate 3 is to drive the installation plate 31 to move horizontally by the sliding of the slider 36.

[0026] Slidably connected to the chute 35 is a slider 36, and the top end of the slider 36 is fixedly connected to the installation plate 31.

[0027] By adopting the above technical solution, setting the slider 36 is to cooperate with the lead screw 37 to drive the installation plate 31 to work.

[0028] Fixedly connected to the bottom end of the bearing plate 3 and near the chute 35 is a support block 34.

[0029] By adopting the above technical solution, a support block 34 is provided at the bottom end of the bearing plate 3 to rotatably mount the lead screw 37.

[0030] The side end of the support block 34 is rotatably connected to a lead screw 37, and the lead screw 37 is in threaded rotational connection with the slider 36.

[0031] By adopting the above technical solution, the lead screw 37 rotates, thereby causing the slider 36 in threaded rotational connection to move horizontally.

[0032] A plurality of bearing rods 38 are fixedly connected to the bottom end of the bearing plate 3, and the other ends of the bearing rods 38 are fixedly connected to the steel beam body 1.

[0033] By adopting the above technical solution, the bearing rods 38 are provided at the bottom end of the bearing plate 3 to prevent the bearing plate 3 from tilting.

[0034] Working principle: When the device is in use, first place the floor slab body 2 above the center of the steel beam body 1. After the insertion plate 21 is inserted into the slot 14, then hook the hook 12 into the connecting ring 22. Subsequently, rotate the knob at the side end of the support block 34, thereby causing the fixedly connected lead screw 37 to rotate, so that the slider 36 in threaded rotational connection moves horizontally under the action of the chute 35. Wait until the limit nut 33 above the slider 36 is at the same level as the screw hole in the floor slab body 2. Then, by rotating the limit nut 33, the effect of connecting the steel beam body 1 and the floor slab body 2 is achieved, thus solving the problems of numerous welding joints and the long time required for connecting the steel beam and the floor slab.
