[0031] An embodiment of the present utility model provides an adjacent wall panel connection structure for prefabricated buildings, as Figures 1-6 shown, the adjacent wall panel connection structure for prefabricated buildings includes:

[0032] A first connecting member 300 and a second connecting member 400, the first connecting member 300 and the second connecting member 400 are respectively connected to different wall panels in a clamping manner;

[0033] The first connecting member 300 and the second connecting member 400 are hinged to each other; the first connecting member 300 includes a first connecting plate 310, a shaft rod 320 and a plurality of groups of assembly rings 330, the second connecting member 400 includes a second connecting plate 410 and a plurality of groups of embedding rings 420, the assembly rings 330 and the embedding rings 420 are alternately butted and embedded, and the shaft rod 320 sequentially passes through the assembly rings 330 and the embedding rings 420 to complete the hinged connection. A limiting component is provided on the assembly rings 330 and the embedding rings 420, and the limiting component abuts against the side wall of the shaft rod 320 after the shaft rod 320 is inserted to prevent further rotation;

[0034] The first connecting member 300 and the second connecting member 400 adopt a hinged connection method, which can allow the included angle between different wall panels to be changed arbitrarily within a certain range, and the wall panel layout requirements in different environments can be met by adjusting the first connecting member 300 and the second connecting member 400; the limiting component provided on the assembly rings 330 and the embedding rings 420 mainly limits the rotation of the shaft rod 320. After the angle adjustment is completed, the limiting components provided on the assembly rings 330 and the embedding rings 420 are tightened in sequence, so as to fix the angular relationship between the wall panels;

[0035] As a preferred implementation manner in this embodiment, the wall panels connected to the first connecting member 300 and the second connecting member 400 are respectively a first wall panel 110 and a second wall panel 200; clamping blocks are provided on the first wall panel 110 and the second wall panel 200, corresponding card slots are respectively provided on the first connecting plate 310 and the second connecting plate 410, and the connection method between the first wall panel 110 and the second wall panel 200 and the first connecting plate 310 and the second connecting plate 410 is mainly the mating connection of the clamping blocks and the card slots,

[0036] Here, the card slots or clamping blocks can be arbitrarily arranged on the first connecting plate 310 and the second connecting plate 410 as needed, as long as different structures are adopted on the corresponding wall panels and the first connecting plate 310 and the second connecting plate 410; this application only facilitates the display of the structural connection characteristics, and the first connecting plate 310 and the second connecting plate 410 are both of card slot structures;

[0037] As a preferred implementation manner in this embodiment, the limiting component includes a limiting chute, a resisting block 441, a bolt hole 442 and a bolt 443;

[0038] The limiting chute and the bolt hole 442 are arranged inside the embedding ring 420 or the assembly ring 330, and the bolt hole 442 extends from the outer wall of the embedding ring 420 or the assembly ring 330 towards the axis direction until it communicates with the limiting chute;

[0039] The limiting sliding groove is arranged on the inner wall of the embedding ring 420 or the assembly ring 330, and the abutting block 441 slides in the limiting sliding groove; a bolt 443 is arranged in the bolt hole 442; when the bolt 443 is screwed in the axial direction, the bolt 443 will push the abutting block 441 to advance along the limiting sliding groove;

[0040] An extension port is provided towards the inner wall of the embedding ring 420 or the assembly ring 330. The side of the abutting block 441 away from the bolt hole 442 extends out of the inner wall of the embedding ring 420 or the assembly ring 330 from the extension port. The abutting block 441 will be in close contact with the outer wall of the shaft rod 320 inserted into the embedding ring 420 or the assembly ring 330, and the friction force on the shaft rod 320 will be increased under the abutting action, thereby preventing the rotation of the shaft rod 320; since the embedding ring 420 and the assembly ring 330 are both relatively locked with the shaft rod 320, the limiting assembly will prevent the first connecting member 300 and the second connecting member 400 from directly deflecting;

[0041] A baffle is provided on the abutting block 441, and under the action of the baffle, the abutting block 441 will not completely slip out of the limiting sliding groove;

[0042] The angle of the first connecting member 300 and the second connecting member 400 is limited by the limiting assembly; the assembly between the first wall panel 110 and the second wall panel 200 is completed;

[0043] In a further preferred embodiment of the present invention, during the assembly process, the shaft rod 320 sequentially passes through the shaft hole channel formed by the embedding ring 420 and the assembly ring 330, and the limiting operation is completed by limiting it respectively. A plurality of groups of threads are arranged at intervals on the outer wall of the shaft rod 320, and the end of the shaft rod 320 provided with threads first enters the shaft hole channel; and the embedding ring 420 is provided with internal threads. When the shaft rod 320 descends to a certain height, the shaft rod 320 is rotated to complete the assembly with the embedding ring 420 by means of thread cooperation, so that there is no need to provide a limiting assembly on the embedding ring 420 for limiting and fixing;

[0044] In this embodiment, the present application can assemble the first connecting member 300 and the second connecting member 400 at the assembly site, and the first connecting member 300 and the second connecting member 400 reach the assembly site in a split structure. Its simple structural characteristics and assembly method can quickly complete the corresponding connection, improve the assembly efficiency while avoiding the situation that the rotating parts are stuck due to transportation during the transportation process, and effectively improve the work efficiency of the construction site;
