What is the function of the bucket arch structure? In which buildings are they used? Please give an example.

The function of the bucket arch structure is as follows:

Bucket arch is a unique structure of China architecture. At the joint of column and beam, the arched load-bearing structure is called arch, and the square block between arches is called bucket. Together, the two are called bucket arches. ?

1. The load is located between the column and the beam, transmitted from the roof and superstructure, transmitted to the column through the bucket arch, and then transmitted to the foundation. Therefore, it plays the role of connecting the preceding with the following to transfer the load.

2. The bulge of the bucket arch makes the eaves of the building more cautious and far-reaching, and the shape is more beautiful and spectacular; And with the development of technology, it has gradually become a decoration (for example, because of the use of brick walls, the eaves are much smaller, and the role of protecting the walls is reduced, and so on). ), become a symbol to distinguish building grades; That is, the nobler, more complex and more prosperous the building is.

3. Bucket arch is a standard component of tenon-mortise combination. Although the space structure combined with tenon and mortise will be "loose", it will not "fall apart", consuming the energy brought by the earthquake, greatly reducing the earthquake load of the whole house and playing an anti-seismic role.

Bucket arch is a structural form of ancient Chinese architecture. It is a concave structure formed by adding a cracked beam between two columns and adding a series of curved wood strips or stone strips on the beam. Bucket arch is an important part of ancient Chinese architecture, which has both practical value and decorative value.

Enhance the stability of the building structure. An important function of the bucket arch is to enhance the stability of the building structure. Under the action of the bucket arch, the weight of the building can be more evenly distributed to all support points to prevent the building from collapsing due to the unstable center of gravity. At the same time, the bucket arch can also bear horizontal force, making the building more stable.

Bucket arches can also beautify the appearance of buildings. The concave structure and curved beauty of the bucket arch make the building more artistic and decorative. In the ancient architecture of China, the bucket arch is widely used in temples, palaces, gardens and other buildings, which has become one of the important features of ancient architecture in China.
