AI Technical Summary
Traditional methods for reinforcing old buildings require a lot of space, involve complicated construction processes, and are costly. There is a lack of a reinforcement solution that requires less space, has a simpler process, and is less expensive.
The reinforcement system combines carbon fiber components and steel compression components. The carbon fiber components are located on the outside of the beam and connected to the structural columns through anchor columns. The steel compression components are sleeved on the outside of the beam and connected by tie anchors to form an integral reinforcement structure.
It improves the structural strength and reinforcement effect of the beams, reduces the occupation of indoor space and the difficulty and cost of construction, and the construction method is simple.
