[0023] For this specific embodiment, by installing the precast beam body 102 on the precast wall panel body 101, the building can be made more stable.

[0024] Among them, the installation cylinder 104 is fixedly connected to the precast wall panel body 101 and is located on one side of the precast wall panel body 101.
