What are the advantages of tenon-mortise structure technology? Do you know that?/You know what? Do you know that?/You know what? The old carpenter told you

China is one of the four ancient civilizations in the world. At that time, many classical crafts and technologies in China were far ahead of the world. The tenon-mortise structure is the most brilliant point of these technologies. The tenon-mortise structure is the connection mode of concave-convex part and two kinds of wood structures. The concave part and the convex part are engaged with each other, which plays the role of connection and stability.

Mortise and tenon (s ǔ n m m m m m m ǐ o) is the main structural mode of ancient buildings, furniture and other appliances in China, and it is the connection mode in which concave and convex parts are combined on two components. The protruding part is called tenon; The recessed part is called the socket. It is characterized by using mortises and tenons to reinforce objects without nails, which reflects the ancient culture and wisdom of China.

The tenon-mortise structure is the oldest traditional craft in China. It is not only firm, but also skillfully cooperates with the contraction and expansion of wood, making wooden furniture stronger, more stable and more durable.

First of all, tenon and mortise have incomparable advantages in the furniture industry.

First of all, furniture with tenon-mortise structure is more durable than furniture connected with nails. This combination can effectively limit the distortion between wooden pieces in all directions. Nail connection can't be done. For example, if nails are used to make a T-shaped combination of two wooden roofs, the vertical roof and the horizontal roof are easy to distort and change their angles, but tenons and mortises will not distort.

Secondly, metals are prone to rust or oxidation, while real solid wood furniture can be used for hundreds or thousands of years. Many Ming style furniture has a history of hundreds of years. Although it is vicissitudes of life, the wood is as hard as ever. If such furniture is combined with nails, it is likely that the wood will be intact, but the furniture will fall apart due to corrosion, fatigue and aging of the connecting metal. So now most people prefer solid wood furniture when decorating.

Thirdly, the combination of tenon and mortise structure improves the horizontal and vertical bite force of solid wood furniture and makes it more stable. It is integrated with the expansion coefficient of solid wood materials and will not change much because of seasonal changes and temperature changes. Compared with the frame furniture assembled with nails, it will start to shake in a short time, and the tenon-mortise structure greatly improves the service life of the furniture and keeps it beautiful.

In addition, mortise and tenon furniture is more convenient to transport. Many mahogany furniture can be disassembled and transported before assembly. But that kind of nailed furniture can't be made.

Then there are high-quality tenons and mortises.

Mortise and tenon are called the "soul" of mahogany furniture. The tenons and tenons on the wooden components are simply engaged, and the wooden components are combined. Because of the different shapes of connecting components, the ever-changing combination mode is derived, which makes mahogany furniture achieve the perfect unity of function and structure.

Mahogany wood is hard, and pushing nails in by squeezing and drilling hard wedges can easily lead to wood splitting, which carpenters know very well. Using mortise and tenon to connect mahogany furniture can greatly improve the internal quality of mahogany furniture, which is also an important reason why mahogany furniture made by traditional technology has value-added collection value.

Another point is that after the mortise and tenon furniture is damaged, only the damaged part can be replaced without replacing the whole furniture.
