What is the lifting frame in the building?

Method for determining the curvature of the roof surface of traditional buildings in China. In this kind of building, when the beams are stacked and raised, the slope of the roof is steeper and steeper by lifting the beams, thus showing a concave surface, which is beneficial to roof drainage and lighting under the eaves, forming a unique style of ancient buildings in China. This method is called scaffolding in the engineering practice of Qing dynasty, folding in the architectural method of Song dynasty and stacking in the source of architectural method, which describes the architectural practice in Jiangnan area. The function and purpose of lifting, folding and folding are the same, but the specific methods are slightly different due to different time or region.

Practice of lifting frame

Qing-style building roof lifting frame

Mainly used for official buildings in the north. In order to ensure rain and snow drainage, it is stipulated that cornice scaffolding of buildings of various sizes should be hoisted five times (that is, the ratio of scaffolding height to scaffolding length is equal to 5: 10) and the rafters should be hoisted three or five times. The height between other scaffolding depends on the size of the house and the number of purlins.

The slope of the ridge frame of the tower or pavilion needs to be appropriately steep, which can reach more than 95 or even10.

Some people in modern architecture also say this word. I think it may refer to the height of a story, or the height of a net. I'm not sure.
