The wood structure building is the essence of the traditional Chinese building and has a long history. The traditional wood structure building in China mainly adopts a mortise-tenon joint frame structure system, and the special bucket arch structure form of the roof layer is ingenious in conception and attractive in form. However, the traditional wood structure mostly takes logs or sawn timber as main material, has large member size and more materials, and depends on natural forestry resources; the fine tenon-and-mortise and bucket arch construction process is complex, the stress is unreasonable, and the fine tenon-and-mortise and bucket arch construction process is difficult to adapt to the development requirements of the modern society. The antique wood structure building mainly adopts modern wood structure building materials and a manufacturing process, has the building characteristics and the appearance of a traditional wood structure, can express the charm of Chinese traditional culture, and is gradually favored by people.
The connection node of the antique wood structure is very important, and particularly, the connection of the roof bucket arch layer not only reflects the building appearance of the traditional wood structure, namely, the wood members are continuous and have no metal connection, but also meets the tension and compression bidirectional stress requirements of the modern wood structure. The traditional wood members in the mortise and tenon joint area are continuous, but the stress has certain limitation, the members for connecting the tenons can only be pressed but can not be pulled, and the mortise and tenon joint has high processing difficulty and is not beneficial to industrial production; the common pin shaft connecting node of modern wood structure uses a large amount of steel, so that the steel connecting piece is not exposed, the filling workload of the bolt hole is large, the member is broken at the node, and the rigidity of the node area is weak. Therefore, a novel rigid connection node is needed for the connection requirement of the pseudo-classic wood structure roof bucket arch layer.
