Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an assembled building connection node. Background Art

[0002] Prefabricated construction is a modern construction method that prefabricates components in factories and then transports them to the construction site for assembly, thereby improving construction efficiency, reducing construction waste, shortening construction cycles, and improving building quality. This construction method has been widely used and promoted around the world. Connection nodes are a key part of prefabricated buildings, which directly affect the overall stability and safety of the building. An excellent connection node design needs to meet multiple requirements such as structural strength, construction convenience, cost-effectiveness, and durability.

[0003] After searching, in the prior art, the Chinese patent application number 202223024032.4 discloses "an assembled building component connection node, comprising two inner wall panels and a connecting wall, wherein one side of the connecting wall is fixedly connected with a connecting piece, one side of each of the two inner wall panels is provided with a rectangular groove, the connecting piece is a T-shaped embedded steel plate, the two sides of the T-shaped embedded steel plate are inserted and connected inside the rectangular groove, the backs of the two inner wall panels are fixedly connected with a fixing mechanism, and the two sides of the connecting wall are provided with a reinforcing mechanism, through which the fixing screw is threadedly connected to the inside of the first connecting groove to fix the L-shaped reinforcing plates on both sides of the connecting wall together, and at this time, the fixing screw is inserted from the threaded hole in the middle of the second connecting groove, so that the other end of the L-shaped reinforcing plate is fixedly connected to the inner wall panel, and the inner wall panel and the connecting wall are fixedly connected together by the L-shaped reinforcing plate, so that the connection has a strong fixity, avoids deformation or loosening of the connection between the inner wall panel and the connecting wall, and makes the wall body have a stronger load-bearing force", but the following defects still exist:

[0004] (1) In the above patent documents, the connection method of the prefabricated building component connection node is mainly for the horizontal connection between the inner wall panel and the connecting wall, and does not involve the connection of the wall in the vertical direction. Therefore, the connection node is only applicable to the horizontal connection of the walls of single-story buildings or multi-story buildings, and cannot be applied to the vertical connection of the walls in multi-story buildings, which narrows its scope of application;

[0005] (2) In the above-mentioned patent documents, the connection nodes mainly rely on the threaded connection of bolts and screws to fix the building panels. During long-term use, due to the tension exerted by the building panels on the connection nodes and the influence of external vibrations, the threaded connection may become loose, reducing the stability and safety of the connection nodes and increasing potential safety risks.

[0006] Therefore, there is an urgent need for an assembled building connection node to solve the above problems. Utility Model Content
