Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] Refer to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present utility model: An adjacent wall panel connection structure based on prefabricated buildings includes two prefabricated wall panels 1 and two cross beams 3. A plurality of fixed support beams 4 are fixedly connected at equal intervals between the adjacent two cross beams 3. Screw rods 5 are fixedly connected to the left and right ends of the two cross beams 3. A plurality of reserved holes 6 are opened in the upper middle parts of the adjacent sides of the two prefabricated wall panels 1. A fixed plate 7 is arranged on the adjacent sides of the two prefabricated wall panels 1. A plurality of expansion bolts 8 penetrate through the adjacent sides of the two fixed plates 7. The far ends of the plurality of expansion bolts 8 are respectively clamped on the inner walls of the plurality of reserved holes 6. The front and rear ends of the tops of the two fixed plates 7 are fixedly connected with moving ears 9. Damping pieces 10 are arranged on the left and right sides of the plurality of moving ears 9. Rotating knobs 11 are fixedly connected to the far sides of the plurality of damping pieces 10. The plurality of screw rods 5 respectively penetrate through the middles of the plurality of moving ears 9, damping pieces 10 and rotating knobs 11. Measuring mechanisms 2 are arranged between the adjacent two of the left end fixed support beams 4 and between the adjacent two of the right end fixed support beams 4;

[0040] Specifically, the cross beam 3 and the multiple fixed support beams 4 fixedly connected thereto form a stable frame structure. The lead screws 5 at the left and right ends of the cross beam 3 are important media for connecting other components. When it is necessary to connect adjacent prefabricated wall panels 1, multiple reserved holes 6 are opened in the upper middle part of the adjacent sides of the two prefabricated wall panels 1, providing fixed points for subsequent connection operations. The fixing plate 7 is placed on the adjacent sides of the two prefabricated wall panels 1. Through multiple expansion bolts 8 penetrating the adjacent sides of the fixing plate 7, the far ends thereof are clamped on the inner walls of the reserved holes 6, thereby realizing the fixed connection between the fixing plate 7 and the prefabricated wall panel 1. Then, the moving ears 9 located at the front and rear ends of the top of the fixing plate 7 play a role in connecting the lead screws 5. The damping sheets 10 provided on the left and right sides of the moving ears 9 can increase the connection stability and friction, preventing loosening of the connection part. By cooperating with the lead screws 5, the knob 11 can adjust the position and tightening degree of the fixing plate 7. Multiple lead screws 5 respectively penetrate through the middles of multiple moving ears 9, damping sheets 10 and knobs 11, realizing the firm connection of adjacent wall panels in the prefabricated building and improving the stability and safety of the building structure.

[0041] Referring to Figure 2 , Figure 4 and Figure 5 , the right end measuring mechanism 2 includes a carrier plate 201. A winding wheel 202 is fixedly connected to the middle of the top wall of the carrier plate 201. A measuring steel rope 203 is arranged on the outer wall of the winding wheel 202. A horizontal U-shaped fixing block 204 is fixedly connected to the right side of the top wall of the carrier plate 201. A terminal fixing groove 205 is fixedly connected to the middle of the top wall of the right moving ear 9. The right end of the measuring steel rope 203 is fixedly connected to a fixed lead block 206. The fixed lead block 206 is clamped on the right side of the terminal fixing groove 205. Measuring pointers 207 are fixedly connected to both the front and rear sides of the top wall of the horizontal U-shaped fixing block 204;

[0042] Specifically, the carrier plate 201 serves as the basic support component of the measuring mechanism 2. Inside the wire winding wheel 202 located in the middle of the top wall of the carrier plate 201, there is a measuring steel wire 203. The measuring steel wire 203 can be retracted and extended in length. When the connection structure changes, the length of the measuring steel wire 203 will also change accordingly. The horizontal U-shaped fixing block 204 on the right side of the top wall of the carrier plate 201 is mainly used to install and fix the measuring pointer 207. The terminal fixing groove 205 in the middle of the top wall of the right moving ear 9 is the fixing point of the right end of the measuring steel wire 203. The fixing lead block 206 at the right end of the measuring steel wire 203 is clamped on the right side of the terminal fixing groove 205 to ensure that the measuring steel wire 203 will not easily break away during the working process. In actual use, when components such as the prefabricated wall panel 1 and the cross beam 3 are displaced, it will drive the moving ear 9 to move. The movement of the moving ear 9 causes the position of the terminal fixing groove 205 to change, thereby pulling the measuring steel wire 203. The change in the length of the measuring steel wire 203 on the wire winding wheel 202 will cause the position of the fixing lead block 206 to change. At the same time, the measuring pointer 207 on the horizontal U-shaped fixing block 204 can indicate the position change of the measuring steel wire 203. By reading the data of the measuring pointer 207, the deformation degree and displacement of the connection structure can be intuitively understood, providing important monitoring information for construction workers so that corresponding adjustment and maintenance measures can be taken in time to ensure the stability and reliability of the connection structure of the prefabricated building.

[0043] Refer to Figure 2 , limit blocks 12 are fixedly connected to the far ends of the multiple lead screws 5 away from each other, and the multiple limit blocks 12 are all in the shape of round cakes; horizontal frames 13 are fixedly connected to the front sides of the top walls of the two carrier plates 201, and multiple spirit levels 14 are fixedly connected to the middle of the two horizontal frames 13; anti-slip grooves 15 are provided on the outer walls of the multiple expansion bolts 8, and the multiple anti-slip grooves 15 are all designed in a cross pattern;

[0044] Specifically, the limit block 12 is fixed to the far end of the lead screw 5 away from each other and is in the shape of a round cake. Its main function is to prevent the moving ear 9, the damping piece 10, and the rotating knob 11 from slipping off the lead screw 5 during the adjustment process, playing a role of limit protection to ensure the stability of the entire connection structure during the adjustment and use process. The horizontal frame 13 is fixed to the front side of the top wall of the carrier plate 201, providing an installation position for the spirit level 14. The spirit level 14 can real-time monitor the horizontal state of the connection structure during the installation and use process. By observing the spirit level 14, construction workers can timely adjust the connection structure to ensure that components such as the prefabricated wall panel 1 and the cross beam 3 are in a horizontal position. The cross-shaped anti-slip grooves 15 on the outer wall of the expansion bolt 8 increase the friction between the expansion bolt 8 and the inner wall of the reserved hole 6 when the expansion bolt 8 is clamped in the inner wall of the reserved hole 6, preventing the expansion bolt 8 from loosening and improving the firmness of the connection between the fixing plate 7 and the prefabricated wall panel 1.

[0045] Refer to Figure 2 and Figure 3, the bottom end of the inner wall of the horizontal U-shaped fixing block 204 and the bottom end of the inner wall of the terminal fixing groove 205 are at the same horizontal height, and the width of the fixing lead block 206 is greater than the inner wall width of the terminal fixing groove 205; the outer wall of the rotating knob 11 is equidistantly provided with grooves 16, and the outer walls of multiple rotating knobs 11 are all designed to be smooth; the two cross beams 3 are in a parallel state, and the two cross beams 3 are perpendicular to multiple fixing beams 4;

[0046] Specifically, the horizontal U-shaped fixing block 204 provides an installation position for the measuring pointer 207 and cooperates with the terminal fixing groove 205 to fix the right end of the measuring steel wire 203. The bottom end of its inner wall and the bottom end of the inner wall of the terminal fixing groove 205 are at the same horizontal height to ensure the accuracy of measurement. The width of the fixing lead block 206 is greater than the inner wall width of the terminal fixing groove 205, and it can be firmly clamped on the right side of the terminal fixing groove 205 to prevent the measuring steel wire 203 from falling off. The grooves 16 on the outer wall of the rotating knob 11 can increase the friction force, which is convenient for construction workers to operate. The smooth outer wall design is not only beautiful but also can reduce the risk of construction workers being scratched during operation. The two cross beams 3 are in a parallel state and perpendicular to multiple fixing beams 4, jointly forming a stable frame structure. The cross beam 3 mainly bears the weight and external force of the prefabricated wall panel 1, while the fixing beam 4 enhances the strength and stiffness of the cross beam 3, improving the stability and load-bearing capacity of the entire connection structure.

[0047] Working principle: The cross beam 3 and multiple fixing beams 4 fixedly connected thereto form a stable frame structure. The lead screws 5 at the left and right ends of the cross beam 3 are important media for connecting other components. When it is necessary to connect adjacent prefabricated wall panels 1, multiple reserved holes 6 opened in the upper middle part of the adjacent sides of the two prefabricated wall panels 1 provide fixed points for subsequent connection operations. The fixing plate 7 is placed on the adjacent sides of the two prefabricated wall panels 1. Through multiple expansion bolts 8 penetrating the adjacent sides of the fixing plate 7, the far ends thereof are clamped on the inner wall of the reserved hole 6, thereby realizing the fixed connection between the fixing plate 7 and the prefabricated wall panel 1. Then, the moving ears 9 located at the front and rear ends of the top of the fixing plate 7 play a role in connecting the lead screws 5. The damping sheets 10 arranged on the left and right sides of the moving ears 9 can increase the connection stability and friction force, preventing the loosening of the connection part. The rotating knob 11 can adjust the position and tightening degree of the fixing plate 7 through cooperation with the lead screw 5. Multiple lead screws 5 respectively penetrate through the middle parts of multiple moving ears 9, damping sheets 10 and rotating knobs 11, realizing the fixation and stability of the entire connection structure;

[0048] Moreover, the carrier board 201 serves as the basic support component of the measuring mechanism 2. A wire winding wheel 202 is provided in the middle of the top wall of the carrier board 201, and a measuring steel wire 203 is arranged inside the wire winding wheel 202. The measuring steel wire 203 can be retracted and extended in length. When the connection structure changes, the length of the measuring steel wire 203 will also change accordingly. The horizontal U-shaped fixing block 204 on the right side of the top wall of the carrier board 201 is mainly used for installing and fixing the measuring pointer 207. The terminal fixing groove 205 in the middle of the top wall of the right moving ear 9 is the fixing point of the right end of the measuring steel wire 203. The fixing lead block 206 at the right end of the measuring steel wire 203 is clamped on the right side of the terminal fixing groove 205 to ensure that the measuring steel wire 203 will not easily break away during operation. In actual use, when components such as the assembled wall panel 1 and the cross beam 3 are displaced, it will drive the moving ear 9 to move. The movement of the moving ear 9 causes the position of the terminal fixing groove 205 to change, thereby pulling the measuring steel wire 203. The change in the length of the measuring steel wire 203 on the wire winding wheel 202 will cause the position of the fixing lead block 206 to change. At the same time, the measuring pointer 207 on the horizontal U-shaped fixing block 204 can indicate the change in the position of the measuring steel wire 203. By reading the data of the measuring pointer 207, the deformation degree and displacement of the connection structure can be intuitively understood, providing important monitoring information for construction workers.
