What are the cornices of ancient buildings? What kinds are there?

Cornice, one of the traditional forms of eaves in China, refers to the eaves, especially the eaves in the corner, rising upwards. It is often used at the corner of the roof of pavilions, platforms, buildings, pavilions, palaces, temples and other buildings. The four corners are spread out, such as birds spreading their wings, which is light and lively, so it is often called cornices.

There are many kinds of cornices, such as pendulous, straight and overhanging. Their different forms have created different artistic effects, either light, simple or majestic. Pavilions, pavilions and buildings should use cornices to identify themselves and express their feelings.

First, the cornices are raised.

The cornice is inclined to enlarge the lighting surface, which is beneficial to the drainage of rainwater and increases the upward movement of the building, as if a gas lifted the eaves upward. The cornices stacked in the middle of the buildings create a spectacular momentum and the unique flying and brisk charm of ancient buildings in China. This architectural technology has both decorative function and practical value, which embodies the magnificence, sculpture, sophistication and grandeur of ancient architecture.

Second, the role of cornice warping

Warping of eaves generally refers to the phenomenon that the four corners of eaves in ancient Chinese wooden buildings are slightly longer than the middle horizontal eaves in both horizontal and vertical directions.

In other words, the cornice on each side is a spatial curve, and both ends rise at a certain angle in the horizontal and vertical directions. But this is not the case under all eaves. In this case, the eaves are generally the main buildings, which are usually deep, but limited by the length of wood, the height is usually not very high, the roof slope is large, and it is often low when reaching the external wall.

But generally speaking, major buildings want a transition space before entering the door (think of the awning that is often set up at the door now), so the roof should go sideways, which will make the indoor with poor lighting worse. Finally, add a layer of flying rafters with smaller inclination on the rafters with overhangs.

I wonder if the subject has folded the paper box. If the carton is folded down along a circle, the four corners will naturally form an angle, and the same is true if the carton is folded down again. From an aesthetic point of view, if you don't tilt the corner, the cornice curve from the side is very ugly.
