What are the common roof forms in ancient buildings?

Many features of ancient architecture are on the roof. Do you know that these places are also the most unique places? The following small series will introduce you to the common roof forms in ancient buildings.

1. Double-eaved Ding Dian: Double-eaved Ding Dian was the highest-ranking Ding Dian in the Qing Dynasty. Ding Dian, also known as Si A Ding, has five ridges and four slopes, and has "four outlets", also known as Wuling Hall. The roof of the temple is rectangular in plan, and its width is greater than its depth. The intersection of the front and rear slopes is a positive ridge, and there are four vertical ridges on the left and right slopes, which cross one end of the positive ridge respectively.

2, the top of the mountain rests on the eaves: the top of the mountain is also called Jiuji Hall. Besides the main ridge and vertical ridge, there are four ridges. The front and rear slopes of the main ridge are full slopes, and the left and right slopes are half slopes.

3. Ding Dian has five ridges and four slopes, with "four outlets", consisting of one main ridge and four vertical ridges, so it is also called Wuling Hall.

4. The sloping mountain roof was called Jiujidian, Caodian or Xiamen in the Song Dynasty and renamed Jiujiding in the Qing Dynasty.

5. The suspended peak is lower than Ding Dian and Xie Ding, only higher than the hard peak. They are only used in folk buildings and are the most common architectural forms. Hanging mountain has one positive ridge and four vertical ridges. It is characterized in that each truss or purlin is not sealed in the mountain walls at both ends like a hard mountain.

6. Hard roof, that is, hard roof, is one of the forms of double-slope roof in traditional buildings in China. The gables on both sides of the house are flush with or slightly higher than the roof.

7. Roll-shed roof, also known as Yuanbaoding, is a kind of roof form of ancient buildings in China. It is a double-slope roof, and there is no big roof ridge where the two slopes intersect. Corrugated roof directly rolls the roof into an arc surface. The overall appearance of the roll top is the same as that of hard mountain and hanging mountain except that there is no obvious positive ridge. The front slope and the roof are curved and rolled back, which has a unique curvy feminine beauty.

Summary: The above are the common roof forms in ancient buildings. I'd like to introduce these kinds of roof forms to you, which are very good and have their own characteristics. I hope the above introduction will be helpful to everyone.
