Most caissons are quadrilateral. What are caissons made of?

Caisson is a traditional decorative pattern, which is common in ancient architecture and art in China, especially in beams, columns, doors and windows of wooden buildings. Algae wells usually consist of quadrangles, in which the pattern consists of the following elements:

Grid: The basic structure of algae wells is a grid-like grid. These squares are usually equilateral or nearly equilateral shapes, which are used to divide the layout of the whole algae well.

Curves: The common pattern elements of algae wells are various curves, such as arcs and twisted lines. These curves are usually used to fill blank areas in the grid to form patterns and decorative effects.

Flowers, birds, insects and fish: the pattern elements that often appear in algae wells include the images of nature such as flowers, birds, insects and fish. These elements can appear alone, or they can be combined to form complex patterns.

Basic geometric figures: You can also see the application of some basic geometric figures in algae wells, such as circles, diamonds and triangles. These graphic elements are combined with squares and curves to form rich and diverse patterns.

The concrete composition and pattern design of algae well patterns vary with the times, regions and styles. In the traditional architecture of China, the caisson is usually regarded as an important decorative art form, showing rich cultural connotation and aesthetic value.
