Origin and source of aluminum alloy bucket arch

  Bucket arch is an antique component with characteristics in ancient Chinese wooden construction
To some extent, it can also be called the symbol of ancient Chinese traditional wooden construction
The bucket arch depends on the tenon (s) ǔ n) Mao structure is a kind of component formed by overlapping and combining a group of small wooden components of bucket arch with each other, which is used for column top and architrave (f) ā NG)
Between eaves and frames, it has the effect of load-bearing connection

  The former history of Dougong is very long
In different ages, the composition and form of Dougong are different, but they are basically composed of two functional parts: one is the & ldquo; Chinese classical decoration used to support the brace beam horizontally or vertically; Arch;, Second, it is located & ldquo; Arch & rdquo; Support and connect all floors & ldquo; Arch & rdquo; Square member & ldquo; Bucket & rdquo& ldquo; Bucket arch & rdquo; From this comes the title of

  According to the structural pictures on some ancient artifacts, it is estimated that the bucket arch appeared when the caisson was built in the Western Zhou Dynasty
From that time until the northern and Southern Dynasties (420-581), the construction of Dougong was carried out
In the Han Dynasty, the purlin (L) was supported by a bucket arch at the top of the column ǐ n) , beam or ground brace of the floor, but each bucket arch is not connected to each other
In the Han Dynasty, bucket arches began to be used between columns, which was called & ldquo; Herringbone arch;, That is, set a fork on the architrave and a bucket on it to support the eaves purlin

  From the Tang Dynasty to the Yuan Dynasty, it was the sophisticated period of Dougong
During this period, the main feature of the bucket arch is that the beams supported by the column head are mostly inserted into the bucket arch structure, the bucket arch and the beam frame are integrated, and the bucket arch becomes the reinforcing node at each intersection
At this time, the bucket arch is no longer an isolated support frame or cornice component, but an integral part of the horizontal structure
During the Tang and Song Dynasties (618-1279), bucket arches were widely used between beams and columns in the hall style construction
The existing main hall of Foguang temple in the Tang Dynasty is a typical representative of this practice
During the Ming and Qing Dynasties (1368-1911), due to the gradual lack of wood, many buildings used various architraves as load-bearing connecting components
The effect of bucket arches gradually decreased, and the shape and system gradually reduced
In some buildings, they have become simple decorative parts
