Chapter 96 Mortise and tenon structure
"Professor Nie, are you sure you want to use a plan that doesn't have a single nail?" Nie Guangyi asked Nie Tianqin.

There is such a sentence in "Min Xiaoji": [The bridge in central Fujian is the most magnificent, and the houses built on the bridge are full of wings, and there are pictures everywhere. 】

Wooden arcade bridges are unique in the history of ancient bridges in the world.

Wooden arched bridges are often built between dense forests in high mountains and dangerous streams in deep valleys, and streams become thoroughfare.

The wooden arched bridges are basically connected by tenon and tenon joints.

When Wan'an Bridge was first built, there were no nails.

"Boss, since we want to restore the Wan'an Bridge to its original appearance, we must use wooden arch bridges with weaving beams to build skills, and we must use logs and traditional wooden construction tools." Nie Tianqin responded.

"Do not use modern tools at all, and use beam weaving technology to connect with mortise and tenon structures. The requirements for craftsmen are quite high, and this is not something I can do alone." Nie Guangyi expressed his opinion.

The construction of the wooden arched bridge needs to be directed by a senior carpenter. This person has always been Grandpa Qiu.

Although Nie Guangyi is talented, after all, he lacks experience in field operations.

There is still a gap between the model and the real build.

In addition, it needs the cooperation of several carpenters at the same time to complete it.

The art of building wooden arch bridges has always been passed down from master to apprentice.

Many of them are not clearly recorded, relying on the feeling and experience of the master.

Nie Guangyi doesn't like this kind of unclear things.

The first thing he does when making a model is digital modeling.

It is still difficult for Nie Guangyi to demand a complete return to "primitive".

Especially the cooperation with Grandpa Qiu's disciples.

Nie Tianqin was extremely persistent on this issue.

He is not opposed to "global material selection", nor is he opposed to the ultimate fireproof treatment for the selected wood. The unique construction skills must be authentic.

"We Chinese have an old saying called [mortise and ten thousand years prison]. Compared with nails, mortise and tenon structure has many advantages."

Nie Tianqin has always admired the mortise and tenon structure.

[tenon, Yan wood enters the orifice.Commonly known as the tenon head, also known as the bamboo shoot head. 】

The mortise and tenon structure is a concave-convex connection method used in wooden furniture and wooden buildings in my country.

The protruding part is called tenon, which is the tenon of mortise and tenon.

The concave part is called mortise, which is the mortise of mortise and tenon.

It's a bit like the relationship between screws and nuts, only more natural and seamless.

The mortise and tenon structure has a long history.

Among the remains of the Neolithic Age in Hemudu, there are mortise and tenon structures, more than 7000 years ago.

As early as the Spring and Autumn Period and the Warring States Period, there were already very mature applications.

It reached its peak during the Tang and Song Dynasties.

By the Ming and Qing Dynasties, the mortise and tenon structure had begun to change from complex to simple.

The mortise and tenon structure does not exist alone.

Each component needs to be organically connected to avoid each other.

It is not practical to use a nail or a trace of metal to complete the construction of reasonable joints, up and down, left and right, thickness and oblique straightness.

Strictly fit, no time allowed.

This requires carpenters, when deciding to build a piece of furniture or a building, to be able to understand the structure of the whole piece of furniture or the whole building.

The mortise and tenon structure has three advantages: high precision, high strength and low cost.

Not to mention rigorous and firm, it can also be easily disassembled and installed.

It was widely used in ancient my country and has been passed down to this day.

Only by the concave-convex fit between the wood, a piece of solid furniture and a solid building can be combined.

It has to be said that it is a very miraculous thing.

The mortise and tenon structure is not only the crystallization of the wisdom of the ancients, but also the witness of human civilization.

More specifically, the traditional construction techniques of wooden arch bridges are to use traditional wooden construction tools and core technologies such as weaving beams to build them, and connect them with mortise and tenon joints to form a stable arch bridge.

With the development of the times, nails and modern tools have already replaced traditional handicrafts.

However, as the "quintessence" of my country's ancient architecture and ancient furniture, mortise and tenon technology still has irreplaceable advantages.

Whether it is the construction techniques of Diaojiaolou in Miao Village, the construction techniques of wooden buildings of the Dong nationality, the traditional construction techniques of wooden arch bridges, or the techniques of Cantonese, Jingzuo, and Ming-style furniture, the mortise and tenon structure is the soul of these techniques.

Compared with modern tools such as nails, the mortise and tenon structure has four advantages.

First, it is more durable.The mortise and tenon structure can withstand the twisting in all directions between the wood pieces.

Second, it is not easy to rust.The ancient rare wood furniture that has been handed down for thousands of years in the museum is all of mortise and tenon structure.

Third, it is easy to disassemble.Mortise and tenon structures are alive.The Wan'an Bridge was washed away by the flood before, but it can be rebuilt because the structure is still there.

Fourth, it is friendly to wood.Driving nails into wood can easily cause the wood to split.

"However, Professor Nie, carpenters who can master the mortise and tenon technique have long been rare. The craftsmanship is too complicated, the structure is too rigorous, and the precision requirements are so high."

"Indeed, if an apprentice carpenter without family inheritance wants to become a teacher in tenon and tenon, it will definitely not work within ten years." Nie Tianqin agreed.

"Professor Nie, this is not the most important thing."

"What do you think is the most important thing?"

"The most important thing is that the requirements are high and the money is low. Even if you learn it, there is not much room for use."

"Why is there no use for it? Doesn't Wan'an Bridge need to be rebuilt?"

"Professor Nie, how often does this happen? The daughter-in-law has become a mother-in-law. In the end, only the old people in the village are left."

"This is indeed the dilemma faced by most non-genetic inheritance. Big head, we have to find a way to make young people willing to participate in the inheritance of these human civilizations."

"It's a bit difficult. A young man with that ability has already gone outside to be a master carpenter. Who still stays in the village?"

"Big head, do you think so too?"

"That's right, it's unrealistic to ask young people to stick to traditional skills without going out to make money."

"Then why did you come back from Italy as an architect? Just to accompany Dad?" Nie Tianqin sighed: "Dad already said that you can have your own development."

"Here is my development."

"Big head, Dad wants to hear the truth."

"Let me tell you this, Professor Nie. The needs of human beings have always been progressive. When young people can't even eat enough to eat, it is difficult for you to pursue higher-level spiritual pursuits."

"The big head means that the inheritance of intangible cultural heritage can only be passed on to us elderly people."

"What kind of understanding is this!" Nie Guangyi retorted: "I mean, a young man like me who is young, rich and talented is the most suitable to be caught and use love to generate electricity."
