[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3A precast concrete wall panel installation and fixing structure includes a vertically arranged wall panel body 1. The outer side wall of the wall panel body 1 is provided with a groove, and the inner right side wall of the groove is provided with a through opening. A bolt head 2 is provided in the groove for driving the bolt rod 3 to rotate. The end of the bolt head 2 away from the bolt rod 3 is provided with an internal hexagonal groove 4 for the user to use an internal hexagonal wrench to rotate the bolt head 3. A horizontally arranged bolt rod 3 is fixedly connected to the outer side wall of the bolt head 2 for fixing the wall panel body 1. The end of the bolt rod 3 away from the bolt head 2 passes through the through opening.

[0022] In this embodiment, a fixing cylinder 6 is fixedly embedded on the inner wall of the opening to support the inner wall of the opening. There is a gap between the inner wall of the fixing cylinder 6 and the bolt rod 3 to allow the bolt rod 3 to move and rotate within the opening. The gap is 1-5mm. Multiple fixing blocks 7 are fixedly connected to the outer wall of the fixing cylinder 6 to support the fixing cylinder 6. The end of the fixing block 7 away from the fixing cylinder 6 is fixedly inserted into the wall panel body 1.

[0023] In this embodiment, a mounting ring 5 is sleeved on the bolt rod 3 for setting a groove to install the slider 10. The mounting ring 5 is fixed on the inner right side wall of the groove. There is a gap between the mounting ring 5 and the bolt rod 3 to allow the bolt rod 3 to move and rotate within the mounting ring 5. The gap is 1-5mm. An anti-loosening washer 14 is sleeved on the bolt rod 3 to prevent the bolt head 2 from loosening. The anti-loosening washer 14 is located between the bolt head 2 and the mounting ring 5.

[0024] In this embodiment, a groove is provided inside the mounting ring 5 near the bottom. A slider 10 is slidably connected to the inner wall of the groove to drive the locking rod 9 to move. Multiple horizontally arranged springs 11 are fixedly connected between the right side of the slider 10 and the inner wall of the groove to provide elastic support for the slider 10. A push block 12 and a horizontally arranged locking rod 9 are fixedly connected to the left side of the slider 10. The push block 12 is used to drive the slider 10 to move, and the locking rod 9 is used to cooperate with the slot to prevent the bolt head 2 from loosening. A rubber pad 13 is fixedly connected to the end of the push block 12 away from the slider 10 to improve the comfort when the hand contacts the push block 12. The ends of the locking rod 9 and the push block 12 away from the slider 10 both slide through the mounting ring 5. Multiple slots 8 corresponding to the locking rod 9 are distributed in a ring on the outer wall of the bolt head 2 to accommodate the locking rod 9.

[0025] In this embodiment, the pressure block 12 is first pushed to move the slider 10 to the right. The slider 10 then moves the locking rod 9 to the right. Subsequently, a screw hole corresponding to the bolt rod 3 is opened on the main structure. The bolt head 2 is turned to rotate the bolt rod 3 and screw the bolt rod 3 into the screw hole. The bolt head 2 presses the wall panel body 1, completing the fixed installation of the wall panel body 1 and the main structure. At this time, the push block 12 is released, and the spring 11 pushes the slider 10 to the left to reset due to its elasticity. The slider 10 drives the locking rod 9 to insert into the slot 8, restricting the rotation of the bolt head 2 and effectively preventing the bolt rod 3 from loosening. This significantly improves the safety and reliability of the wall panel body 1 after installation.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
