Various mortise and tenon manufacturing methods

Various mortise and tenon manufacturing methods are as follows:

1. tenon: This tenon-mortise structure is mainly used to fix the joint of two plates. It is a trapezoidal wood chip with an inclined plane on one side. After the two plates are spliced, the dovetail is inserted into the gap, and the inclined plane makes it expand naturally, thus fixing the two plates together.

2. Digging hookah tenon: This tenon structure is mainly used to connect the joint of two boards. It is a semi-circular wooden block with a cavity in the middle. Insert the joint of one of the wooden boards into the cavity, and then tap the wooden block gently with a mallet to expand it and fix it at the joint.

3. Chuck tenon (the upper ends of legs and feet are embedded with toothed bars and toothed heads): This tenon structure is mainly used to fix the legs and toothed bars of chairs. It embeds the rack into the groove at the upper end of the leg and fixes the rack and the leg together with tenons.

4. Fan-shaped mortise and tenon: This mortise and tenon structure is mainly used to fix the joint of two arc-shaped wooden boards. It is a fan-shaped wooden block with an inclined plane on one side. After the two arc-shaped wooden boards are spliced, the fan-shaped mortise tenon is inserted into the gap, and the inclined plane makes it expand naturally, thus fixing the two wooden boards together.

The function of mortise and tenon:

1, tenon and mortise are mainly used to connect two wooden components and make them combine stably. The tenon and mortise combine the whole component into a whole through the concave-convex structure, which changes the stress mode of the building. Through layer-by-layer transmission, the stress points of the whole building become more balanced and the overall structure is more stable.

2. The tenon-mortise structure can not only bear a large load, but also allow some deformation. Under the earthquake load, deformation can offset some earthquake energy and reduce the seismic response of the structure. Mortise and tenon technology is an important structural combination of ancient buildings, furniture and daily appliances in China, and it is recognized as the most natural and mechanical building connection technology in the world.
