[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figures 1-4 As shown in the figure, this application discloses a connection mechanism between a precast floor slab and a wall, including a wall 1, a precast floor slab 11, reinforcing bars 12, a connecting assembly 3, adjusting bolts 4, annular blocks 5, sliding rods 6, and sealing plugs 7. The precast floor slab 11 is installed on the upper surfaces of two mutually symmetrical walls 1. Multiple mutually symmetrical pre-drilled holes 13 are provided through the upper surface of the precast floor slab 11. The reinforcing bars 12 are fixedly installed within the walls 1, and the reinforcing bars 12 are matched with the pre-drilled holes 13. Reinforcing bar 12 connectors (not shown in the figure) are provided on the reinforcing bars 12 for fixing the precast floor slab 11 to the walls 1.

[0030] When workers need to connect the precast floor slab 11 to the wall 1, they must align the reinforcing bars 12 with the pre-drilled holes 13. Then, the workers install the precast floor slab 11 onto the wall 1. Subsequently, the workers fix the precast floor slab 11 to the wall 1 using the reinforcing bar 12 connectors. During this process, the workers further secure the precast floor slab 11 to the wall 1 using the connecting components 3, thereby reducing the probability of the precast floor slab 11 shaking if the reinforcing bar 12 connectors are damaged, thus improving the stability of the device.

[0031] A pre-reserved groove 2 is formed on the upper surface of the wall 1, and a sliding groove 21 is formed on the inner wall of the pre-reserved groove 2. A connecting component 3 is set on the precast floor slab 11 and the wall 1 to connect the precast floor slab 11 and the wall 1. The connecting component 3 includes a connecting rod 31, a sliding plate 32, and a fixing block 33. The connecting rod 31 is slidably set in the pre-reserved groove 2 and is fixed to the precast floor slab 11. Multiple fixing grooves 22 are arrayed on the side wall of the connecting rod 31. The sliding plate 32 is slidably set in the sliding groove 21. Multiple fixing blocks 33 are provided and fixedly set on the side wall of the sliding plate 32 near the fixing groove 22. The fixing blocks 33 and the fixing grooves 22 are matched with each other.

[0032] When the worker needs to further fix the prefabricated floor 11 and the wall body 1, the worker needs to slide the sliding plate 32 towards the direction close to the fixing groove 22, so that the fixing block 33 slides towards the direction close to the fixing groove 22 under the action of the sliding plate 32, so that the fixing block 33 slides into the fixing groove 22, and then the fixing block 33 fixes the connecting rod 31 in the reserved groove 2, thereby further fixing the prefabricated floor 11, thereby reducing the probability of shaking of the prefabricated floor 11 when the reinforcing steel bar 12 connecting piece is damaged, and thereby improving the stability of the device.

[0033] The side wall of the wall body 1 is provided with a rotating groove 23 penetrating through, and the rotating groove 23 is in communication with the sliding groove 21. The adjusting bolt 4 is rotationally arranged in the rotating groove 23, and the axis thereof is horizontal. The adjusting bolt 4 is threadedly connected with the sliding plate 32.

[0034] When the worker needs to slide the sliding plate 32, the worker needs to rotate the adjusting bolt 4, so that the sliding plate 32 slides towards the direction close to the fixing groove 22 under the action of the adjusting bolt 4, thereby reducing the difficulty of the worker in sliding the sliding plate 32, and thereby reducing the working difficulty of the worker.

[0035] An annular groove 24 is formed in the inner wall of the rotating groove 23, and the annular block 5 is rotationally arranged in the annular groove 24. The axis of the annular block 5 coincides with the axis of the adjusting bolt 4, and the annular block 5 is fixed with the adjusting bolt 4.

[0036] When the worker rotates the adjusting bolt 4, the annular block 5 rotates synchronously with the adjusting bolt 4 under the action of the adjusting bolt 4. In this process, the annular block 5 limits the adjusting bolt 4, thereby reducing the probability of sliding of the adjusting bolt 4, and thereby improving the stability of the device.

[0037] The sliding rod 6 is provided with two sliding rods 6 which are symmetrically arranged on the inner wall of the sliding groove 21. The two sliding rods 6 penetrate through the sliding plate 32 and are slidably connected with the sliding plate 32. The side walls of the two sliding rods 6 abut against the side wall of the connecting rod 31.

[0038] When the sliding plate 32 slides under the action of the adjusting bolt 4, the sliding plate 32 relatively slides with the sliding rod 6. In this process, the sliding rod 6 limits the sliding plate 32, thereby reducing the probability that the sliding plate 32 rotates with the adjusting bolt 4 when the worker rotates the adjusting bolt 4, and thereby improving the stability of the device.

[0039] The sealing plug 7 is arranged in the rotating groove 23. The side wall of the sealing plug 7 is flush with the side wall of the wall body 1. The sealing plug 7 is made of rubber material.

[0040] When the worker rotates the adjusting bolt 4 to slide the fixing block 33 into the fixing groove 22, the worker needs to install the sealing cover made of rubber into the rotating groove 23, so that the sealing cover seals the rotating groove 23, thereby improving the appearance of the surface of the wall body 1.

[0041] In order to reduce the working difficulty of the worker, the end of the fixing block 33 away from the sliding plate 32 is provided with a chamfer 8. The chamfer 8 reduces the probability of the fixing block 33 sliding into the fixing groove 22, thereby reducing the working difficulty of the worker.

[0042] The use principle of the connecting mechanism between the prefabricated floor and the wall body in the embodiment is as follows: when the worker needs to connect the prefabricated floor 11 and the wall body 1, the worker needs to align the reinforcing steel bar 12 with the reserved hole 13. At this time, the worker installs the prefabricated floor 11 on the wall body 1. Then, the worker fixes the prefabricated floor 11 on the wall body 1 through the reinforcing steel bar 12 connecting piece. In this process, the worker further fixes the prefabricated floor 11 and the wall body 1 through the connecting assembly 3, thereby reducing the probability of the prefabricated floor 11 shaking when the reinforcing steel bar 12 connecting piece is damaged, thereby improving the stability of the device.

Any technical solution falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled persons in the technical field, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
