Is the ancient mortise and tenon really as powerful as people say? Where are the highlights?

It's really amazing. Because this technology can connect objects without a nail, and it has been strong for hundreds of years, the preserved mortise and tenon building is the best endorsement.

It's really so powerful, and a lot of things happen there, the first highlight is that the scenery is very beautiful and has a lot of personality, the second is that the environment is like a fairyland on earth, foggy, and the third is that the climate there is very good, and the people there live more than 100 years.

The ancient mortise and tenon joints are really powerful, and in the construction process of the building, there is no need to use any nails, and the building can be built extremely strong.

As early as 7,000 years ago in the Hemudu cultureThe mortise and tenon technique has appeared in the wooden houses where the primitive ancestors lived.

Mortise and tenon joint (is the main structural method of ancient Chinese architecture, furniture and other equipment, is a connection method that combines concave and convex parts on two components. The protruding part is called tenon (or tenon); The recessed part is called Mao (or tenon, tenon).

It is characterized by the fact that no nails are used on the objects, and the objects are reinforced with mortise and tenon, reflecting the ancient Chinese culture and wisdom.

Furniture Chinese furniture connects the various parts of the "mortise and tenon" method, which is the main structural way of furniture modeling. The various mortise and tenon joints have different practices and different application ranges, but they have the "joint" role of the shape structure on each piece of furniture.

If the mortise and tenon joints are used properly, the two wooden structures can be tightly fastened to the extent that they are "seamless". It is the basic skill that ancient carpenters must have, and the level of craftsmanship of craftsmen can be clearly reflected through the structure of mortise and tenon.

China's achievements in engineering construction from ancient times to the present have always been very high, not to mention the world miracle Great Wall, the Forbidden City, in recent years, it has been called the infrastructure madness by the world, and countless miracles of building bridges have been born in the hands of Chinese. Behind these achievements, it is inseparable from the unremitting efforts of the craftsmen of the great countries. The culture of the Chinese, adhering to the openness and integration, has been integrating with the construction technology and culture of all countries in the world, and has been innovating and developing.

Many of our construction techniques have influenced other countries and peoples and have been passed down to the next generation. One of these excellent inheritances has to be mentioned, that is, mortise and tenon technology.

The mortise and tenon joint can be traced back to the wooden buildings of the Hemudu period about 7,000 years ago in China, and there were already very obvious design and application projects at that time. Our ancestors evolved from nest dwelling to dry pen dwelling, and this application technology was born. The application of mortise and tenon technology comes from the wood itself, and the elasticity of wood will be more and more closely combined in long-term use.

It can also achieve a good seismic effect. Mortise and tenon is known as the "soul" of Chinese furniture, due to the different forms of connecting components, which derives a kaleidoscopic combination, so that Chinese furniture to achieve the perfect unity of function and structure.

With the progress of science and technology, there are many materials that can replace the structural function of mortise and tenon, such as aluminum, glass fiber, etc., which are not only simple to make, but also reduce costs to a certain extent, so that the furniture can be formed at one time, and there is no need to use mortise and tenon joints to connect, which is troublesome to operate, high cost and waste of materials. In addition, the function of the mortise and tenon structure is to connect the plates, so as to ensure the strength of the furniture. The mortise and tenon structure has high requirements for the hardness and quality of the material, generally only mahogany and nanmu can be made of mortise and tenon structure, and the domestic mahogany is higher, and the complexity of the mortise and tenon structure process is added, so it is rarely seen now.

The most common is the lattice shoulder tenon. When making a lattice shoulder tenon, you need to open a square tenon in the middle of the wooden block, and then make two inclined bevels next to the tenon, called the tenon shoulder. Among them, the one with a wallet is called''False shoulders'', the one without leather armor is called''Solid shoulders''。

The existence of the wallet is mainly to increase the friction between the wooden blocks, so it comes with a wallet''False shoulders''It's a little stronger. It is precisely because of the particularity of this structure that it is difficult for the wooden block to be twisted by external force, making the object more durable.

Because this structure has a very unusual design, there are a lot of fits in the structure, so that it can be very strong.

Because the structure is tightly fastened, using a structure such as surface to surface and surface to point, it is strong even without nails.

Because two pieces of wood can be connected seamlessly, the degree of fit is very high, and there are no gaps.
