According to the principle of mechanics, a variety of fir and pressure strips are added, and the stiffness of the node is celebrated, forcing the angle to remain unchanged and fixing the bracket.

Chen Wenyuan, an expert in ancient architecture, is in awe of traditional culture, and has experienced more and more ancient buildings leaving their hometowns, and deeply feels the pain of cultural tearing. He decided to quit his job and return to his hometown with his son to the countryside in search of cultural roots and meaning of life.

His wife, Sula, a real estate architect, was adamantly opposed to his plan to return home. At this time, he unexpectedly saw his father Chen Shouzhuo at the construction site of the scenic spot, and on the mountain road that stretched for miles, the building fragments that were carried were his family temple Chen Clan Ancestral Hall, thousands of miles away.

During the Spring and Autumn Period and the Warring States Period, mortise and tenon joints developed from the use of architecture to the use of furniture. During the Qin and Han dynasties, the wooden frame of the main body became more and more mature, and the mortise and tenon structure also developed.

A traditional carpenter craft in ancient China, which refers to the use of wood concave and convex splicing on two components, the protruding part is called "tenon", and the recessed part is called "mao", and the mortise and tenon joint fit, so that the wood and wood are perfectly connected.

The mortise and tenon joint is the crystallization of the wisdom of the working people, which fully embodies the creativity and artistry of human beings. It is the main structural method of ancient Chinese architecture, furniture and other equipment, and its existence avoids the destruction of wood by nails, and it is very stable and reliable.

The mortise and tenon structure is an extremely ingenious invention, and the nodes between the individual components are matched by mortise and tenon joints to form an elastic framework, so that the traditional Chinese wooden structure can offset a certain amount of seismic energy through deformation under seismic loads. When the mortise and tenon member is subjected to more pressure, it becomes stronger. The old wooden buildings have survived many earthquakes, and mortise and tenon joints have played a key role.

The mortise and tenon joint process is a necessary skill of ancient craftsmen, and the level of craftsmanship of craftsmen can be clear through the structure of mortise and tenon joints. If the mortise and tenon joints are used properly, the two wooden structures are tightly fastened to achieve "seamless".

In ancient times, the whole set of furniture and even the whole house did not use an iron nail, but it could be used for hundreds or even thousands of years, which was a miracle in the history of human light industry manufacturing, and these were the merits of mortise and tenon.

Mortise and tenon is known as the "soul" of solid wood furniture, the design of Chinese classical furniture is different from traditional handicrafts, mortise and tenon technology should not only be exquisite in appearance, meet people's visual beauty, but also follow the principle of mechanics, scientific and reasonable, practical, durable, not easy to rust and easy to disassemble.

Every piece of wood is permeated with the painstaking efforts of ancient craftsmen. The mortise and tenon craft is the great wisdom of the ancient Chinese, which gives a soul to the seemingly lifeless furniture.

The art of mortise and tenon is the spirit of craftsmanship in the bones of the Chinese, and every woodworking designer may have a dream about tenon and tenon. As the essence of traditional Chinese architecture and furniture craftsmanship, the mortise and tenon structure can be firmly held together through various nested structures without any hardware or glue, and it can be said that the mortise and tenon structure is the embodiment of top craftsmanship.

When the ancient craftsmen chiseled off the excess, the two pieces of wood would be close to each other and no longer separated. Due to the time-consuming and laborious production of tenons and tenons, more and more mortise and tenon joints have been gradually abandoned in the era of modern machinery production and the pursuit of efficiency.

The inheritance of mortise and tenon craftsmanship can not only preserve the classic woodworking technology, but also provide an important reference and basis for current home design. It is a great traditional Chinese skill, and every time you look at the details of these ancient buildings, you can't help but want to travel back.

During the Spring and Autumn Period and the Warring States Period, mortise and tenon joints developed from the use of architecture to the use of furniture. During the Qin and Han dynasties, the wooden frame of the main body became more and more mature, and the mortise and tenon structure also developed.

The charm of the mortise and tenon structure, how to make a sheet without nailing, and can be freely disassembled and assembled.

Since this table is composed of a pure mortise and tenon structure, the standard requirements for mortise and tenon joints will be very high when making, and it is best to do some assistance.

At what time did mortise and tenon begin to enter the people's gods? In the Neolithic Age, about six or seven thousand years ago, the Hemudu people had been using it. During the Spring and Autumn Period and the Warring States Period, mortise and tenon joints developed from the use of architecture to the use of furniture.

During the Qin and Han dynasties, the wooden frame of the main body became more and more mature, and the mortise and tenon structure also developed, and mortise and tenon bricks, tongue and groove bricks, and wedge bricks appeared. According to the "Xijing Miscellaneous Records", Hu beds appeared during this period.

During the same period, the Western Regions Zen bed was also introduced to China, and the Zen bed was still wide and still sat on the ground. During the Wei, Jin, Southern and Northern Dynasties, the ethnic groups were integrated. The cultural, economic and other aspects of the exchanges of various ethnic groups have been deepened, which has also played a role in promoting the development of furniture. Mortise and tenon joints also developed.

Until the Sui and Tang dynasties, mortise and tenon joints entered the heyday of development at the same time as furniture and architecture, high-type furniture developed rapidly, and wooden buildings were precise and solid. The aesthetics of the Song Dynasty reached its peak, and everything was humanistic, and at the same time, the promulgation of the "Construction of the French Style" was a sign that ancient Chinese architecture had reached a higher stage of development.

At that time, "dougong" in a word, is to reduce the stressed beams and columns into zero, into hundreds of small components, and then these small components with the relationship between mortise and tenon to form a large component, so that many nodes are generated, dissolve external forces, and transfer weight. The wooden tower of Yingxian County, Shanxi Province is a bucket arch interspersed with a beam column structure, which is built through the mortise and tenon link, and the construction method is extremely simple but can withstand thousands of years of wind and rain.

During the Ming and Qing dynasties, the furniture craftsmanship was exquisite, and there were more than 100 kinds of mortise and tenon structures used. The building is concise and concise, presenting a restrained but steady and rigorous style. The largest wooden structure built in the Ming Dynasty is the Forbidden City.

In the modern period, thousands of years of continuation are all based on the oral transmission of craftsmen, with the gradual disappearance of the "master and apprenticeship", the traditional mortise and tenon structure of the production skills are slowly changing and integrated into modern life, more and more people began to inherit and carry forward this traditional craft.

Hemudu Town, Yuyao City, found a Neolithic cultural site six or seven thousand years ago, people called the Hemudu site, in the site people found a large number of mortise and tenon structures.

During the Spring and Autumn Period and the Warring States Period, mortise and tenon joints developed from the use of architecture to the use of furniture. During the Qin and Han dynasties, the wooden frame of the main body became more and more mature, and the mortise and tenon structure also developed.

Because of the charm of the mortise and tenon structure, Eucalyptus began to learn how to make a sheet that does not need to be nailed and can be freely disassembled and assembled.

Since the table is made of a combination of pure mortise and tenon structure, the standard requirements for mortise and tenon will be very high when making, and it is best to assist some power tools and wood.

First, 11 long boards and 30 short boards were made according to the design size, and grooved with bakelite milling. Then make four table bearing squares, and then combine them into a table support frame. Then the four legs are stuck on the frame of the table in turn, and finally the lattice table top with staggered length can be installed on it, and the specific steps are below.

Step 1: Creative Design

The table is made up of four backs and four legs, which are combined with a creative trident tenon. The frame of the table bearing is mm, and the size of the wood is 30mm square. The table adopts 11 horizontal plates and 30 vertical plates, the size of the plate is 30*10mm, and the intersection uses clip tenons to bite each other (as shown in the figure).

Step 2: Make the Tabletop Board

The whole desktop is a lattice shaped desktop made of 11 horizontal boards and 30 vertical boards, first milled with bakelite on the wooden board with a thickness of 30mm, a width of 450mm, and a length of not less than 300mm, and milled out 11 grooves of 10*15mm according to the design size, and then sawed out 30 pieces of 10mm thick wooden plates with a chainsaw. In the same way, 11 long transverse boards are made according to the design size, and then sanded off the wood chips and dust on the wooden boards with fine sandpaper.

Step 3: The table bears the legs

The table bearing is a frame type composed of two long (horizontal) and two short (vertical) ones. Two long (horizontal) ends are milled with a 15*15mm tenon and groove above the bakelite milling, and a 15*15mm tenon and groove is also milled on the inside (as shown in the figure).

On the upper outer side of the two short (vertical) (as shown in the figure), a 15*15mm tenon is milled with bakelite milling, and then a round tenon is chiseled by hand to make it a round tenon with a diameter of 15mm.

The four legs are also made of square wood. According to the design, at the upper end of the table leg, use bakelite milling to make a 15*15mm square tenon (as shown in the figure) at the inner end of the outside of the table leg.

Because this table is composed of pure mortise and tenon structure, the standard requirements for mortise and tenon will be very high when making, it is best to assist some power tools, and the wood should also choose some wood with high density and certain hardness.

Step 4: Assemble smartly

It's time to put on a show of real technology! Many wood friends have asked me, "How do you make the structure formed by the intersection of three pieces of wood?" Let's uncover the secret. In fact, it is very simple, it is composed of three sets of clamp tenons, one of which needs to be made into a circle, and then assembled (as shown in the figure).

Specifically: first clamp the short (vertical) round tenon end of the table bearing on the long (horizontal) tenon and groove, and pay attention to the round tenon facing outward (opposite direction). Snap the table leg (square tenon) into the tongue and groove, and then turn the round tenon end 90° counterclockwise. After the square material is returned to its place, the three pieces of wood intersect and bite each other, forming the legendary "trident tenon".

As early as ancient times, the mortise and tenon structure was used in architecture, and the emergence of hardwood furniture represented by Ming-style furniture pushed the mortise and tenon technology to a technical peak.

The charm of the mortise and tenon structure, how to make a sheet without nailing, and can be freely disassembled and assembled.

Since this table is composed of pure mortise and tenon structure, the standard requirements for mortise and tenon will be very high when making, and it is best to assist some power tools and wood.

In ancient China, mortise and tenon structures were used in both architecture and furniture. The Chinese timber building framework generally includes basic components such as columns, beams, fangs, backing plates, sandalwood, bucket arches, rafters, and lookout boards.

These components are independent of each other and need to be connected in a certain way to form a house. The "mortise and tenon" method of connecting various parts of Chinese furniture is the main structural method of furniture modeling.

The various mortise and tenon joints have different practices and different application ranges, but they have the role of "joints" of the shape and 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 the craftsman can be clearly reflected through the structure of the mortise and tenon joint.

Mortise and tenon structures can be broadly divided into three main types:

The first type is mainly the joint of surfaces and surfaces, the combination of two edges, and the junction of surfaces and edges. Such as "notch tenon", "tongue tenon", "dovetail tenon", "wear belt tenon", "tie tenon" and so on. The other type is the structural approach as a "point". It is mainly used for horizontal and vertical T-joint, angular combination, cross combination, as well as extension joint of straight and arc materials.

Such as "lattice shoulder tenon", "double tenon", "double clamp tenon", "hook tenon", "wedge tenon", "half tenon", "through tenon" and so on. There is also a construction method that combines three components together and connects them with each other, which is more complex and special in addition to the use of some of the above mortise and tenon joint structures. For example, the common ones are "supporting angle tenon", "long and short tenon", "shoulder tenon", "zongjiao tenon" and so on.

The mortise and tenon joint is a very ingenious invention, this component connection method, so that the traditional Chinese wood structure has become a special flexible structure that surpasses the contemporary building frame, frame or rigid frame, which can not only bear a large load, but also allow a certain deformation, and offset a certain amount of seismic energy through deformation under the seismic load, and reduce the seismic response of the structure.

The rational use of mortise and tenon joints and the precision of production are not only directly related to whether the structure of the furniture is rigorous and firm, affecting the service life of the furniture, but also related to the beauty and artistry of the furniture. If a piece of furniture is full of nail holes and joints are distorted, it cannot be regarded as a 'usable' piece of furniture, let alone artistic and collectible value.

With the development of science and technology, the soul mortise and tenon structure of furniture has long been forgotten by people, replaced by nails and glue in the stage of large industrial production, because the benefits obtained after cost compression are more attractive.

The level of craftsmanship of ancient craftsmen can be clearly reflected through the mortise and tenon structure. Therefore, the mortise and tenon structure is the soul of the carpenter.

Behind the mortise and tenon structure, there is also a hidden mystery.

Two pieces of wood, one concave and one convex, one yin and one yang, complement each other and coexist.

Just like the yin and yang poles of Tai Chi, it embodies the philosophical thought of the ancients that "heaven and man are one, and virtual and real are born together".

Through ups and downs, those buildings that have stood for thousands of years, what gives them eternity?

It is the seamless tenon and tenon and tenon, which will never be abandoned, creating a thousand-year-old legend and creating the companionship of the earth.

Mortise and tenon is the soul of classical furniture, between a tenon and tenon, when a turn and a turn, it condenses the essence of China's thousands of years of traditional furniture culture and precipitates the beauty of Ambilight.

The mortise and tenon joint is the soul hidden in the wood.

A tenon and a tenon, a turn and a fold, hidden mysteries.

Mortise and tenon joints, without a nail, can make ingenious furniture, natural, seamless.

It is the essence of Chinese furniture and the foundation of Chinese architecture.

Mortise and tenon joint, a kind of Chinese beauty that has amazed for thousands of years......
