[0003] Utility model patent CN221502356U discloses a connection device and tightening device for precast wall panels at concealed columns. While this patent solves the problems of time-consuming, labor-intensive, and inefficient methods used by construction workers to connect the reinforcing bars of cast-in-place sections to the reinforcing bars of precast wall panels in concealed locations, and the difficulty in transporting and the increased risk to construction workers due to the pre-existing outward-protruding structural reinforcing bars on the sides of existing precast wall panels, this utility model patent still has the following drawbacks:

[0004] In the existing technology, the alignment and connection process of precast concrete wall panels and reserved steel bars usually relies on the auxiliary operation of tower cranes and the guidance of installation workers. This results in the entire alignment and connection process being not only time-consuming but also relatively inefficient, ultimately affecting the accurate adjustment and rapid installation of the precast concrete wall panel position, and thus restricting the progress of construction. Therefore, a fixing and connection device for precast concrete wall panels is proposed. Summary of the Invention

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1

[0024] Please see Figures 1-4This utility model provides a technical solution: a fixing and connecting device for precast concrete wall panels, including a main support plate 3, with inclined support rods 2 symmetrically fixedly connected to the lower surface of the main support plate 3, and a support base 1 fixedly connected to the bottom of the inclined support rods 2. An electric hydraulic rod 4 is fixedly connected to the lower surface of the main support plate 3, and a movable plate 5 is fixedly connected to the output end of the electric hydraulic rod 4. A steel wire rope 6 is installed on the lower surface of the movable plate 5, and a hook 7 is connected to the steel wire rope 6. A fixing pin 8 is inserted into the bottom end of the hook 7. A precast concrete wall panel body 9 is arranged below the movable plate 5, and the top of the precast concrete wall panel body 9 is fixedly connected to... A connecting ring 10 is attached, which is connected to a hook 7. A threaded rod 11 is provided below the support base 1. One end of the threaded rod 11 is fixedly connected to a threaded rod 12. Positioning plates 13 are threadedly connected to the outer walls of both the threaded rod 12 and the threaded rod 11. Telescopic rods 141 and springs 142 are fixedly connected to the side of the two sets of positioning plates 13 near the support base 1. The telescopic rods 141 and springs 142 are fixedly connected to the support base 1. Stirrups 15 are evenly fixedly connected to both sides of the precast concrete wall panel body 9. Reserved steel bars 18 are evenly provided below the precast concrete wall panel body 9.

[0025] Example 2

[0026] A fixing connection device for precast concrete wall panels, wherein a handle 16 is fixedly connected to the end of threaded rod 11 away from threaded rod 12, the threaded directions of threaded rod 11 and threaded rod 12 are opposite, and threaded rod 11 and threaded rod 12 are parallel to telescopic rod 141. Threaded rod 11 and threaded rod 12 are used to control the distance between positioning plates 13, thereby limiting the precast concrete wall panel body 9 according to the position of the reserved reinforcing bar 18 through the positioning plates 13.

[0027] In this embodiment, specifically: a set of casters 17 are fixedly connected to the lower surface of the support base 1. The number of casters 17 is multiple and they are evenly distributed. The casters 17 facilitate the movement of the precast concrete wall panel body 9 by the workers. The inclined support rod 2 is inclined to one side of the precast concrete wall panel body 9. An auxiliary support rod 19 is fixedly connected to the lower surface of the precast concrete wall panel body 9. The auxiliary support rod 19 is fixedly connected to the support base 1. The electric hydraulic rod 4 is electrically connected to an external power source. The electric hydraulic rod 4 used in this application is prior art. The connection between the electric hydraulic rod 4 and each component is also prior art. Therefore, its connection and working principle will not be described in detail here.

[0028] Working principle: When workers need to install the precast concrete wall panel body 9 using the fixing connection device for precast concrete wall panels, the precast concrete wall panel body 9 is moved to the vicinity of the reserved reinforcing bar 18 by a crane and lowered. Workers move the fixing connection device for precast concrete wall panels above the precast concrete wall panel body 9, pull out the fixing pin 8, and activate the electric hydraulic rod 4. The electric hydraulic rod 4 extends, causing the moving plate 5 to move downwards. The wire rope 6 and hook 7 then move closer to the precast concrete wall panel body 9. When the hook 7 is located on both sides of the connecting ring 10, the fixing pin 8 is inserted back in. The precast concrete wall panel body 9 is then connected through the cooperation of the connecting ring 10 and the fixing pin 8. Controlling the electric hydraulic rod 4 to shorten it causes the electric hydraulic rod 4 to move the moving plate 5, hook 7, and precast concrete wall panel body 9 upwards until the precast concrete wall panel body 9 is 1 meter above the ground. The fixing and connecting device for the precast concrete wall panel pushes the precast concrete wall panel body 9 above the reserved reinforcing bar 18. Turning the handle 16 causes the two sets of positioning plates 13 to move closer to each other in sync. Adjusting the position of the fixing and connecting device for the precast concrete wall panel until the bottom of both positioning plates 13 are in contact with the reserved reinforcing bar 18 ensures that the precast concrete wall panel body 9 is directly above the reserved reinforcing bar 18, thus completing the positioning of the precast concrete wall panel body 9. Then, turning the handle 16 until the distance between the positioning plates 13 is greater than the thickness of the precast concrete wall panel body 9 allows the precast concrete wall panel body 9 to pass through. Then, the moving plate 5 is controlled by the electric hydraulic rod 4 to move the precast concrete wall panel body 9 downward. During the installation process, there is no need for the staff to repeatedly communicate with the crane operator to push and adjust the precast concrete wall panel body 9, making the entire alignment and connection process less time-consuming and relatively efficient.
