Luo Guoyu is also called the bridge, and it appears in many furniture styles such as the Eight Immortals table, the official hat chair, and the case. It is generally used for the crossbars connecting the leg columns under the furniture of tables and chairs. Because the middle is high arched, the two ends are low and named like a pot.
Luoguoyu is one of the structural shapes often seen in ancient Chinese furniture. It is also an important reference for judging the furniture age.
The origin of Luo Guoyu
During the Sui and Tang Dynasties, high-grade furniture was popularized in China, especially in the Song Dynasty. The frame-like structure replaced the box-and-board structure as the mainstream of furniture modeling, and the frame between the frames also had room for development and evolution. The early pull was straight, and later, for the sake of decoration, there was an arched curved pot.
During the Yuan and Ming Dynasties, Gao Gong Luo Guoyu had been used independently in furniture. However, due to the lack of lighting in the living room at that time, the furniture in the room was relatively small, and it was often used for a variety of uses and mobile use. The mechanical strength of the high arched pot was difficult to meet the requirements of use.
At the end of the Yuan Dynasty and the beginning of the Ming Dynasty, there was a top-height high-arched pot, which had good mechanical strength and was very popular in furniture. In the handed down Ming and Qing hardwood furniture, the structure of Luoguoyu added dwarf scorpion and scorpion flower is quite common, and many of them have been designated as classics of Mingzhi furniture by various academic works.

What is "one leg, three teeth, Luopan"
The Ming style non-waist square table or painting table has a unique form called “one leg, three teeth, and a potâ€, most of which are beautiful in shape and outstanding in appearance.
One leg three teeth
"One leg and three teeth" is named because each leg of the table intersects with the left and right long teeth and the head of the table corner. "Root Pot" is a scorpion that rises in the middle to increase the space in the lower part. From the structural point of view, each leg of the table is fixed by three teeth in the direction, the legs and feet have a certain side angle, and the stability of the table is sufficient. But as a rule, why is it that "one leg and three teeth" must be matched with "roast pot"?
In order to install three teeth, the legs are uncomfortable at the four corners of the table and are slightly retracted, so that the side is wide and the table top is ejected. The resulting table corner is similar to the flying horn of the classical Chinese wooden structure. The head of the table corner is similar to the corner beam and the corner of the flying raft. Viewed from the side, the curved shape of the three strips on the upper part of the leg and the Luopan pottery visually creates a static change in the symmetry of the table corner.

Ankazi flowers between the teeth of the furniture and the Luochao, the carved flowers are the carved wooden blocks between the table top and the rafters. Their functions can not be ignored, which can strengthen the stability of the frame structure of the table and the load-bearing of the table top. Through the scorpion to guide the legs and feet, it is still the finishing touch on the decoration.

Colombo's mix with dwarf
The short columns are commonly called dwarf scorpions. They are generally used in groups. They are grouped in two groups, with two groups on the long side and one on the short side. The shape of Luoguoyu is not very meaningful in structural mechanics. The reason for this is to increase the space under the armpit and increase the use function, while at the same time breaking the straight and rigid format, adding furniture to the artistic vitality. .
Roasted pots and dwarfs are usually used in conjunction with each other, and their function is to fix the four legs and support the table top. These parts are used on low-waisted or non-waisted tables and benches. The so-called Luopan 枨, that is, the middle part of the 枨 略 is slightly higher than the two heads, arched, or "bridge shape", and now the southern craftsmen also call it "bridge". In the north, people like to describe the two low-headed, middle-high bridges with human hunchbacks, called "roofs bridges", so the furniture parts similar to Luopanqiao are collectively referred to as Luoguoyu. In the middle of the Luopanyu, most of the short columns are connected to the upper desktop.
