[0023] The technical problem of lack of adjustment raised in the embodiment of the present invention is solved by designing an installation mechanism, including a rotating assembly, a clamping assembly and a transmission assembly, so as to achieve precise positioning and firm clamping of the wall panel body 3 in the fixed frame 2.

[0025] Embodiment 1; See also Figure 1-Figure 8 In an embodiment of the present invention, an assembled autoclaved aerated concrete exterior wall panel connection device includes: a fixed connecting plate 1, a fixed frame 2 is installed on the top of the fixed connecting plate 1, and a wall panel body 3 is installed in the inner cavity of the fixed frame 2; a mounting mechanism, the mounting mechanism is located in the inner cavity of the fixed frame 2 and is used for connecting the wall panel body 3 and the fixed connecting plate 1, the mounting mechanism includes a rotating component, a clamping component and a transmission component, the rotating component is located in the inner cavity of the fixed frame 2 and is used to drive the movement of the clamping component, the clamping component is located on one side of the rotating component and fixes the wall panel body 3 laterally, and the transmission component is located on the other side of the rotating component and is used for transmission between rotating components; a clamping mechanism, the clamping mechanism is located inside the clamping component and is used for installing the thickness of the wall panel body 3.

The installation screw holes 5 use standard M12 threads and are matched with high-strength stainless steel installation screws 6 with a tensile strength of ≥800MPa to ensure a firm connection between the wall panel body 3 and the corner protection shell 4. The connection strength meets the requirements of GB50009-2012 "Building Structure Load Code".

[0027] The working principle of the embodiment of the present invention is: during the installation process of the assembled autoclaved aerated concrete exterior wall panel, the entire connecting device is first firmly installed on the predetermined building structure by fixing the connecting plate 1, and the fixed frame 2 serves as the bearing structure of the wall panel body 3, and its internal space is designed with a precise installation mechanism for fixing and installing the wall panel body 3.

[0028] The wall panel body 3 is connected to the edge and corner protection shell 4 through the mounting screw holes 5 and the mounting screw rods 6. The combination of the high-strength stainless steel screw rods and the standard M12 threads ensures the firmness and durability of the connection and meets the requirements of the building structure load specifications.

[0029] Embodiment 2; See also Figure 1-Figure 8In the embodiment of the present invention, a trapezoidal template 7 is installed at the bottom of the corner protection housing 4, and a slide groove 8 is provided on the outer side of the trapezoidal template 7. A sliding assembly is slidably connected in the inner cavity of the slide groove 8 to facilitate the trapezoidal template 7 to enter the fixed frame 2. The sliding assembly includes a pulley 9 slidably connected in the inner cavity of the slide groove 8, a limited telescopic rod 10 is installed on the inner wall of the fixed frame 2, the limited telescopic rod 10 is connected to the pulley 9, and a first spring 11 is installed on the outer ring of the limited telescopic rod 10. The two sides of the first spring 11 are respectively connected to the fixed frame 2 and the pulley 9. The pulley 9 is provided in two groups and is symmetrically distributed. The limited telescopic rod 10 and the first spring 11 are provided in two groups and are symmetrically distributed.

[0030] The rotating assembly includes rotating screw holes 12 opened on both sides of the fixed frame 2, and the inner cavity of the rotating screw hole 12 is threadedly connected with an adjusting screw 13, and the adjusting screw 13 is provided in two groups and is symmetrically distributed. The clamping assembly includes a clamping frame 14 installed on one side of the adjusting screw 13 and used for horizontal clamping and fixing the wall panel body 3. The adjusting screw 13 and the clamping frame 14 are connected through a bearing, and the clamping frame 14 is provided in two groups and is symmetrically distributed. A stable telescopic rod 15 is installed between the fixed frame 2 and the clamping frame 14. The transmission assembly includes a rotating rod 16 installed on the other side of the adjusting screw 13, a support seat 17 is installed on the top of the fixed connecting plate 1, and a transmission telescopic rod 18 is rotatably connected in the inner cavity of the support seat 17, and the rotating rod 16 and the transmission telescopic rod 18 are connected through a belt 19, and the rotating rod 16 and the belt 19 are provided in two groups and are symmetrically distributed.

[0031] The working principle of the embodiment of the present invention is as follows: first, the corner protection housing 4 and the trapezoidal formwork 7 at the bottom thereof are pre-positioned on both sides of the wall panel body 3. The design of the trapezoidal formwork 7 not only enhances the protection of the edge of the wall panel, but also provides a guide path for the sliding assembly through the slide groove 8 opened on its outer side. When the trapezoidal formwork 7 needs to enter the fixed frame 2, the sliding assembly begins to play a role, and the pulley 9 slides smoothly in the inner cavity of the slide groove 8, reducing friction resistance and improving installation efficiency. At the same time, the combination of the limiting telescopic rod 10 and the first spring 11 provides stable support and elastic buffering for the pulley 9. As the trapezoidal formwork 7 gradually goes deeper, the limiting telescopic rod 10 is appropriately extended, and the first spring 11 undergoes elastic deformation to store energy, thereby ensuring a smooth transition and precise positioning of the trapezoidal formwork 7 during installation.

[0032] Once the trapezoidal template 7 completely enters the fixed frame 2, the rotating assembly starts to operate. The adjusting screw 13 rotates in the rotating screw hole 12 through a threaded connection, driving the clamping frame 14 to move along the inner wall of the fixed frame 2. The bearing connection between the adjusting screw 13 and the clamping frame 14 ensures the flexibility of rotation and the stability of clamping. At this time, the stable telescopic rod 15 plays an auxiliary supporting role to prevent the clamping frame 14 from deflecting or shaking during the clamping process. The transmission assembly is responsible for transmitting the power of the rotating assembly to the other side to ensure the synchronous movement of the clamping frames 14 on both sides. The rotating rod 16 is connected to the transmission telescopic rod 18 by a belt 19 to form a stable transmission chain. As the transmission telescopic rod 18 is extended and retracted, the belt 19 drives the rotating rod 16 to rotate, thereby driving the adjusting screw 13 on the other side to rotate, realizing the synchronous clamping action of the clamping frame 14.

[0033] Embodiment 3; See also Figure 1-Figure 8 In the embodiment of the present invention, the clamping mechanism includes a mounting telescopic rod 20 mounted in the inner cavity of the clamping frame 14, a squeezing plate 21 is mounted on one side of the mounting telescopic rod 20, and a second spring 22 is mounted between the mounting telescopic rod 20 and the squeezing plate 21. A fixing screw hole 23 is provided in the inner cavity of the fixed connecting plate 1, a fixing screw 24 is threadedly connected in the inner cavity of the fixing screw hole 23 and is used to fix the connection between the connecting plate 1 and the ground, and multiple groups of fixing screw holes 23 and fixing screws 24 are provided and distributed in a rectangular array.

[0034] The working principle of the embodiment of the present invention is as follows: the clamping mechanism further enhances the installation stability and firmness of the wall panel body 3. When the clamping frame 14 is tightly fitted to the side of the wall panel body 3, the clamping mechanism begins to work, and the installation telescopic rod 20 pushes the extrusion plate 21 to approach the wall panel body 3 under the action of the internal spring force. As the extrusion plate 21 gradually approaches, the second spring 22 undergoes elastic deformation to store energy, while ensuring that the extrusion plate 21 applies uniform and appropriate pressure to the wall panel body 3. When the extrusion plate 21 is completely fitted to the wall panel body 3, the clamping block on one side of the extrusion plate 21 automatically snaps into the preset slot of the trapezoidal template 7, realizing the precise positioning and firm locking of the wall panel thickness.

[0035] Finally, the fixed connecting plate 1 is firmly connected to the ground through the fixing screw hole 23. The fixing screw hole 23 adopts a standard thread design and cooperates with a high-strength fixing screw 24 to ensure a stable connection between the connecting device and the ground. The rectangular array distribution of multiple groups of fixing screw holes 23 and fixing screws 24 further enhances the reliability and durability of the connection.
