[0002] In the field of antique architecture, especially in the restoration of historical sites and the design of new Chinese-style buildings, ridge decoration is an important part of the building's appearance. It not only carries rich cultural connotations, but also has important structural and waterproof functions. However, traditional ridge decoration systems mostly use materials such as clay and wood, which have problems such as heavy weight, poor durability, and susceptibility to damage due to climate, resulting in high maintenance costs. In addition, the installation process of ridge decorations made of traditional materials is complicated and the construction efficiency is low, making it difficult to adapt to the needs of rapid construction of modern buildings.

[0046] Combined with the above technical structure, the operation steps of the technical solution are as follows:

[0047] The first step is to install the ridge foundation support structure:
