榫å¯, pronounced sÇ”n mÇŽo, is a combination of bumps and joints used on two wood members. The protruding part is called 榫 (or hoe); the concave part is called å¯ (or blinking, grooving), and 榫 and å¯ are engaged to play a connecting role. This is the main structural form of ancient Chinese architecture, furniture and other wooden equipment. The æ¦«å¯ structure is a combination of 榫 and å¯, which is an ingenious combination of multiple and small, high and low, long and short between pieces of wood, which can effectively limit the twisting of wood pieces in all directions. The most basic æ¦«å¯ structure consists of two members, one of which is inserted into the other's mortise, connecting and fixing the two members. The part of the skull that protrudes into the blink is called the tongue, and the rest is called the shoulder. The æ¦«å¯ structure is widely used in construction and is also widely used in furniture, reflecting the close relationship between furniture and architecture. After the æ¦«å¯ structure is applied to the building, although each component is relatively thin, it can withstand tremendous pressure as a whole. This structure is not the strength of the individual, but the combination of each other and the mutual support. This structure has become the basic model of the descendant architecture and Chinese furniture. æ¦«å¯ is an extremely delicate invention. China began to use it 7000 years ago. This type of component connection makes Chinese traditional wood structure a special flexible structure that transcends contemporary building shelves, frames or rigid frames. It bears a large load and allows a certain deformation to be absorbed. Under seismic load, a certain seismic energy is absorbed by deformation to reduce the seismic response of the structure. æ¦«å¯ Structures are organized by structure and can be roughly divided into three types: The face and the face are mainly the joint of the face and the face, or the combination of the two sides, or the interface of the face and the edge. Such as "notch 榫", "Qiaokou 榫", "Dovetail 榫", "wearing 榫", "Zha 榫" and so on. Another type of point structure is a structural method as a "point". Mainly used for the combination of horizontal and vertical materials, angling, cross-joining, and extension of straight and curved materials. Such as "shoulders", "double shackles", "double shackles", "hook 榫", "锲 榫", "half 榫", "overnight" and so on. Another type of combination member is a constructor and three members in combination with the other, as this method except for some tenon joint use of the above structure, are some of the more complex and specific practices. Such as the common ones are "Tuojiao", "long and short", "holding shoulders", "corner" and so on.
