Technical Field
[0001] This utility model relates to the field of prefabricated building wall panel technology, specifically a connection structure for prefabricated building wall panels. Background Technology
[0002] With the rapid development of industrialized construction, prefabricated buildings have become an important development direction in the modern construction industry due to their advantages such as high construction efficiency, less environmental pollution, and controllable component quality. As the core enclosure and partition components of prefabricated buildings, the performance of the connection structure of wall panels directly affects the overall safety, airtightness, and construction efficiency of the building.
[0003] In prefabricated building construction, traditional wall panel connection structures mostly use a single bolt connection method. While this method can provide a certain connection strength, it requires tightening a large number of bolts one by one during installation, which is cumbersome, time-consuming, and seriously affects construction efficiency. Moreover, bolt connections have extremely high requirements for installation accuracy; even a slight deviation can lead to misalignment of bolt holes, increasing on-site rework costs. In addition, single bolt connections lack an elastic buffer mechanism, and when the building is subjected to dynamic loads such as earthquakes, wind, or temperature changes, stress concentration can easily occur, causing bolts to loosen or even break, posing structural safety hazards. This makes it difficult to meet the requirements of rapid construction and high reliability in prefabricated buildings. Therefore, we need to propose a connection structure for prefabricated building wall panels. Utility Model Content
[0004] The purpose of this utility model is to provide a connection structure for prefabricated building wall panels to solve the problems mentioned in the background art.

[0011] Preferably, the spring is arranged horizontally, the horizontal plate is symmetrically installed at the left and right ends of the spring, and the third vertical plate is symmetrically installed on both sides of the horizontal plate and extends to the top of the wall panel to form a pinch.
[0012] Preferably, the reinforcing component includes an upper bolt and a lower bolt, both of which are horizontally installed on the side of the wall panel. One end of the upper bolt and the lower bolt penetrates the side of the wall panel and extends into the interior of the wall panel, respectively connecting to the side of the first vertical plate and the second vertical plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-6 This utility model provides a technical solution: a connection structure for prefabricated building wall panels, including a wall panel 1 and a slide rail 2. The bottom of the wall panel 1 is provided with a horizontally extending groove 3. The cross-sectional shape of the groove 3 is adapted to the top contour of the slide rail 2. The wall panel 1 is used to form a prefabricated building wall. Horizontal installation and positioning are achieved through the cooperation of the bottom groove 3 and the slide rail 2. The slide rail 2 is fixed to the building foundation. Its top contour is adapted to the bottom groove 3 of the wall panel 1, providing horizontal support and guidance for the wall panel 1. The groove 3 extends horizontally along the bottom of the wall panel 1 and forms a sliding pair with the slide rail 2, so that the wall panel 1 can move horizontally and be positioned along the slide rail 2.
[0026] A connecting component for connecting wall panels 1 is installed at the joint of the wall panel 1. The connecting component includes a first vertical plate 4, a triangular tenon 5, and a second vertical plate 7. The first vertical plate 4 and the second vertical plate 7 are respectively fixed to the opposite edge of the wall panel 1 by high-strength bolts. The first vertical plate 4 is used to install the triangular tenon 5, which cooperates with the second vertical plate 7 of the adjacent wall panel 1 to realize the splicing of the wall panel 1. The bottom of the first vertical plate 4 and the second vertical plate 7 also has a groove 3 that cooperates with the slide rail 2. The triangular tenons 5 are evenly distributed on the surface of the first vertical plate 4 away from the wall panel 1. The triangular tenons 5 are inserted into the triangular grooves 6 of the adjacent wall panel 1 to provide vertical positioning and preliminary shear resistance connection. The second vertical plate 7 has a triangular groove 6 that cooperates with the triangular tenon 5, and the depth of the triangular groove 6 is greater than the height of the triangular tenon 5. The second vertical plate 7 is fixed to the other edge of the wall panel 1, and the triangular groove 6 is opened to cooperate with the triangular tenon 5 to form a mortise and tenon connection, which enhances the splicing accuracy.
[0027] The surface of the connecting assembly is equipped with a spring locking assembly for locking the wall panels 1 together. The spring locking assembly includes a spring 8, a horizontal plate 9, and a third vertical plate 10. The spring 8 is installed on the surface of the triangular tenon 5. The spring 8 generates a preload through elastic deformation, which drives the horizontal plate 9 to slide into the square groove 13 to achieve locking. The spring 8 is made of 65Mn manganese spring steel, which has high strength, high elasticity and good fatigue resistance, and can ensure that it is not easy to undergo plastic deformation or breakage during frequent compression and reset. The two ends of the spring 8 are welded and fixed to the fixing seat on the surface of the triangular tenon 5. The fixing seat and the triangular tenon 5 are integrally formed. When the spring fails due to elastic decay, breakage or other failures, it can be replaced and maintained by disassembling the third vertical plate 10. The triangular tenon 5 and the first vertical plate 4 are integrally formed and fixedly connected. The horizontal plate 9 and the square groove 13 of the second vertical plate 7 slide together, and the position of the wall panel 1 is locked by the force of the spring 8 into the square groove 13.
[0028] Spring 8 is horizontally positioned, and horizontal plates 9 are symmetrically installed on the left and right ends of spring 8. The third vertical plate 10 is symmetrically installed on both sides of horizontal plate 9 and extends to the top of wall panel 1 to form a pinch. The third vertical plate 10 is a detachable structure. The horizontal plate 9 is controlled to slide and unlock by manually pinching and compressing spring 8. The horizontal thrust generated by earthquake or wind is first borne by horizontal plate 9. Horizontal plate 9 converts the load into spring 8 preload through the elastic deformation of spring 8. Part of the load is transferred to the second vertical plate 7 through square groove 13. The remaining load is resisted by the shear resistance of upper bolt 11 and lower bolt 12.
[0029] A reinforcing assembly for reinforcing the wall panels 1 is installed on the outside of the wall panel 1. One end of the reinforcing assembly extends into the interior of the wall panel 1 and is connected to one end of the connecting assembly. The reinforcing assembly includes an upper bolt 11 and a lower bolt 12. The upper bolt 11 and the lower bolt 12 are both installed laterally on the side of the wall panel 1. One end of the upper bolt 11 and the lower bolt 12 penetrates the side of the wall panel 1 and extends into the interior of the wall panel 1, respectively connecting to the side of the first vertical plate 4 and the second vertical plate 7. The upper bolt 11 and the lower bolt 12 penetrate the wall panel 1 laterally and are fastened to the first vertical plate 4 and the second vertical plate 7, providing rigid reinforcement and improving the overall pull-out and shear strength.
[0030] A square groove 13 is formed inside the second vertical plate 7. The size of the square groove 13 is adapted to the size of the spring 8 and the horizontal plate 9. The square groove 13 is formed inside the second vertical plate 7 to accommodate the spring 8 and the horizontal plate 9, providing installation space for the spring locking assembly and restricting the movement trajectory.
[0031] A sealing rubber strip 14 is provided at the joint of the wall panel 1. The sealing rubber strip 14 is embedded in the square groove 13 near the top edge of the corresponding third vertical plate 10. When the wall panel 1 is spliced, it is compressed to fill the joint gap and achieve waterproof, sound insulation and sealing functions.
[0032] First, fix the slide rail 2 to the building foundation. Then, slide the wall panel 1 with the slide groove 3 horizontally along the slide rail 2 to the predetermined position to complete the positioning. Next, fix the first vertical plate 4 and the second vertical plate 7 of the adjacent wall panel 1 to the edge of the wall panel 1 with high-strength bolts. Push the wall panel 1 so that the triangular tenon 5 is inserted into the triangular groove 6 to achieve a preliminary vertical connection. Then, pinch the third vertical plate 10 to compress the spring 8. After it is in place, release it so that the horizontal plate 9 slides into the square groove 13 to lock. Then tighten the upper bolt 11 and the lower bolt 12 to pass through the wall panel 1 and secure it to the first vertical plate 4 and the second vertical plate 7 to complete the rigid reinforcement. During the process, the square groove 13 of the second vertical plate 7 accommodates the spring locking assembly and restricts its movement. The sealing rubber strip 14 is compressed to fill the gap and achieve waterproof sealing.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
