[0027] Specifically, Figure 1-Figure 5As shown, the overall shape of the lower clamping plate 3 and the overall shape of the upper clamping sleeve 4 are both L-shaped plates, and the surface of the lower clamping plate 3 and the surface of the inner wall of the upper clamping sleeve 4 are both provided with anti-slip grooves. The L-shaped plate shape of the lower clamping plate 3 and the upper clamping sleeve 4 can ensure the clamping and locking effect of the concrete precast panel 1 and the concrete precast panel 2.

[0028] Furthermore, the positioning assembly includes a locking plate 15 and a locking groove 16, wherein the locking plate 15 is fixedly connected to the bottom of the bonding plate 8, and the locking groove 16 is provided on the bottom of the inner wall of the bonding groove 7, and the inner wall of the locking groove 16 and the surface of the locking plate 15 are engaged and adapted, and through the setting of the locking plate 15 and the locking groove 16, the precise positioning and clamping position of the precast concrete panel 1 and the precast concrete panel 2 can be quickly found.

[0029] Specifically, Figure 1-Figure 5 As shown, the number of the plug-in plates 6 and the number of the plug-in slots 5 is at least five, and the number of the plug-in plates 6 and the plug-in slots 5, which are at least five, are evenly distributed on the concrete precast panel 1 and the concrete precast panel 2.

[0030] Example 2 Please refer to Figure 1-Figure 5The difference between this embodiment and embodiment 1 is that the main bodies of the concrete precast panel 1 and the concrete precast panel 2 are both concrete main panels, and the top and bottom of the concrete main panels are fixedly connected with anti-corrosion protective plates 14. The concrete main panels can play a basic supporting and firming effect, and the anti-corrosion protective plates 14 can provide protection in the upper and lower directions.

[0031] Working principle of the utility model: when in use, since the concrete precast panels will be produced in the factory, but the actual use location is different from the factory location, the side groove 10 can be used to clamp and install the corner guard frame 11, so as to protect the four corners of the concrete precast panels such as the concrete precast panel 1 1 and the concrete precast panel 2 2. Since the bolt ring 17 is provided on the corner guard frame 11, it can be pulled to change its position. Since the main body of the corner guard frame 11 is a seismic plate, it can play the role of seismic support. The addition of the wear-resistant pad 18 can play the role of wear-resistant mutual abutment, so as to realize the stacking and placement of the concrete precast panels in the upper and lower positions. Since the interior of one end of the seismic plate is fixedly connected with a vertical rod 19, it can play the role of side support, so that the two abutting support plates 21 in the upper and lower seismic plates can abut each other, and the movable support effect can be freely adjusted under the action of the spring telescopic rod 20. The addition of the elastic protective sleeve 22 can make its internal spring telescopic rod 20 wrapping protection, when the concrete precast panels are moved to the installation site, the staff can assemble and lock the concrete precast panels 1 and 2 in batches. When connecting the concrete precast panels 1 and 2 to the left and right, the lower clamping plate 3 and the upper clamping sleeve 4 can be used to make the left and right abutment clamping sleeves of the concrete precast panels 1 and 2, and then the bonding plate 8 can be clamped and placed in the inner wall of the bonding groove 7. Through the setting of the clamping plate 15 and the clamping groove 16, the accurate positioning clamping position can be quickly found, and then the positioning screw 9 is rotated to enter the internal thread groove inside it for locking and positioning. Through the setting of the plug-in plate 6 and the plug-in groove 5, the front and rear positions of the concrete precast panels can be plugged and positioned. The addition of the anti-skid cross plate 13 and the anti-skid cross groove 12 can enhance the clamping and locking effect, thereby ensuring the protection of the concrete precast panels during transportation and the assembly effect of the multi-point constraint method.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
