Description
Technical Field
[0001] The utility model relates to the technical field of mortise and tenon joints of ancient buildings, in particular to a mortise and tenon joint structure of an ancient building frame. Background Art
[0002] The mortise and tenon structure originated from ancient Chinese wooden structures, dating back to the Neolithic period. With the evolution of the times, this structure gradually matured and was widely used in various buildings such as palaces, temples, and residential buildings. The mortise and tenon structure uses wood as the main material. Through the concave and convex combination of the tenon and the mortise, the components are tightly connected without the use of metal connectors such as nails or screws. This unique connection method not only makes the building structure stable and durable, but also has extremely high aesthetic value. The mortise and tenon structure is often used for connection in ancient buildings. The combination of the mortise and tenon structure and the modern fixing method can have excellent connection and fixing effects while being beautiful.
[0003] A mortise and tenon connection node between a steel tube beam and a steel tube side column is disclosed in Chinese patent CN202320170746.1. The mortise and tenon connection node between the steel tube beam and the steel tube side column uses the mortise and tenon connection technology to open holes and U-shaped grooves on the surface of the steel tube side column, open a U-shaped groove on the surface of the first steel tube beam, and set a first channel steel mortise and tenon connection piece and a second channel steel mortise and tenon connection piece. Through the penetration and mutual engagement between the components and assisted by weld connection, a connection node with superior performance is formed. However, the mortise and tenon connection node between the steel tube beam and the steel tube side column is used for vertical connection and fixation between the end plates of the steel tube beam, and has poor connection stability for parallel plate structures.

Compression springs 7 are fixedly connected to both sides of the inner wall of the assembly groove 2, and one end of the compression spring 7 is fixedly connected to the inner side of the first assembly block 3. By arranging helical teeth on the first assembly block 3 and the second assembly block 4, the second assembly block 4 can complete a preliminary snap-fit with the first assembly block 3 after entering the assembly groove 2. The engagement of the two enables the second assembly block 4 to remain stable when subjected to outward pulling force. Arranging a compression spring 7 on the inner side of the first assembly block 3 can enable the first assembly block 3 to generate an outward force, so that the two assembly blocks fit more closely and improve the assembly fit.
