What is a bucket arch and what is its function?
1, which plays a connecting role.
Bucket arch is the part that connects the eaves with load-bearing columns and beams, and the weight of the whole roof is naturally transferred to the columns through the bucket arches in different positions. The bucket arch bears the load handed down from the beam frame and transfers it to the main beam, and then to the eaves through the column foundation. It can support the protruding eaves so that the eaves can be further picked out to protect the walls and abutments. Indoor smallpox can also support the formation of indoor smallpox. In a multi-storey building with a cross seat, the bucket arch is the supporting component of the cross seat, so the bucket arch is an important structural component in ancient Chinese architecture.
2, play an earthquake-resistant role
The bucket arch forms a crisscross pavement between beams and columns, just like adding a layer of spring between beams and columns, which can effectively resist earthquake forces. Therefore, many excellent ancient buildings in our country, including multi-storey pavilions and towering towers, can still stand tall after many strong earthquakes.
Step 3 play a decorative role
Shading under the eaves, the main colors are mostly "cool colors", such as blue and green, and the patterns are slightly dotted with Phnom Penh; The columns, doors and walls are dominated by danchi, which just forms a color pair with the cool paintings on the arch under the eaves, and at the same time sets off the white abutment, which also gives the red wall and yellow tile a chance to breathe.
The structure of the bucket arch is criss-crossed, with various forms, varieties, bright colors and orderly rhythm, which makes the bucket arch an important decorative component in ancient Chinese architecture.
4. Building grade mark
In the feudal society of China, only important buildings, such as palaces, tombs, gardens, temples and temples, used bucket arches. At the same time, the shape of the bucket arch has also become a symbol of architectural grade. Therefore, the bucket arch is a patent of the royal building, and the residential buildings can't be used, but the temples or ancestral halls can be used, that is, the bucket arch goes up three steps. A royal building like the Forbidden City usually steps on the arch seven or even nine times.
