School / mahogany furniture, why can't use nails

Red wooden furniture, why not use nails? This seemingly simple topic has a deep mystery. The following conclusions will be understood after reading.

First, the study found that as early as 7000 years ago in the Hemudu Neolithic Age, our ancestors had already begun to use it. That is to say, the 榫卯 structure is a unique craft creation of the Chinese nation and has a long history.

For more than 70 centuries, this art process has been continuously developed and re-created, and its technology and craftsmanship have become proficient. The reason why Chinese traditional furniture (especially the Ming and Qing furniture) reached today's level has a direct relationship with the use of this structural feature, and it is precisely the use of this clever structure that promotes the artistic value of Chinese furniture, especially the country. Mama furniture and architectural artists are amazed. Therefore, it can be said that Chinese furniture does not use iron nails. It is a tradition, it is a customary convention, and it is the continuation and development of the upper hand. The reason why Chinese furniture is called traditional furniture is that the structure is the core.

Second, the furniture of the 榫卯 structure combination is more durable than the furniture connected with the nails.

First, the 榫卯 structure is a combination of 榫 and ,, which is a clever combination of multiple and small, high and low, long and short between pieces of wood. This combination can effectively limit the direction between the pieces of wood. Wriggle. The nail connection can't be done. For example, the two rafts are made into a T-shaped combination with nails. The mullion and the sill are easily twisted to change the angle, and when combined with 榫卯, they will not be distorted.

Second, metals are easily rusted or oxidized, while real mahogany furniture can be used for hundreds or thousands of years. Many Ming-style furniture have been around for hundreds of years, and although they are vicissitudes, the wood is as hard as ever. If such furniture is combined with nails, it is likely that the wood is intact, but the furniture is scattered because of the corrosion, fatigue, aging, etc. of the connected metal.

Third, the structure of the furniture is easy to transport. I don't see a lot of mahogany furniture. It is disassembled and transported. It is very convenient to assemble and install it at the destination. If the furniture is connected with nails, it can be made into a split type of the department, but furniture such as a chair with more small pieces of wood can not be done.

Fourth, the structure of the furniture is easy to maintain. No matter what kind of furniture, it will take a long time to use it, and it needs maintenance and maintenance. Pure mahogany furniture can be used for hundreds of thousands of years, and there will always be problems, such as the need to replace a certain scorpion. Furniture that is connected by nails is not as easy to replace as structural furniture. If it is made of glue such as fish gelatin, the glue will be soaked in soft water during maintenance, and the nail will be loosened quickly, but it can't be done with nails unless the furniture is unloaded. In turn, it causes damage to the furniture.

Fifth, because the mahogany wood is hard, and the nail is hardened by the squeezing and drilling, this process is very easy to cause the wood to split, which is very clear to the carpentry master. Through the above comparison, we do not lose face, the use of 榫卯 to connect mahogany furniture has a greater advantage than the use of nails, can greatly promote the intrinsic quality of mahogany furniture, which is probably why the pure mahogany furniture does not use nails.
