[0010] Preferably, anchor tension bars are arranged in the first column casting groove, the second column casting groove, the third column casting groove, the first wall casting groove, the second wall casting groove and the third wall casting groove. One end of each anchor tension bar is embedded and the other end is exposed. The anchor tension bars in the first column casting groove, the second column casting groove, the third column casting groove, the first wall casting groove, the second wall casting groove and the second wall casting groove do not extend out of the grooves.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By making the side faces of the first wall body and the second wall body close to the indoor side respectively flush with the side faces of the left and right ends of the load-bearing column close to the indoor side, and making the left and right side faces of the third wall body respectively flush with the side faces of both sides of the front end of the load-bearing column, it is convenient for the later construction of the inner wall surface. The outer sides of the first wall body and the second wall body wrap the load-bearing column, avoiding the influence of the external environment on the load-bearing column and prolonging its service life.

[0013] 2. Through the arrangement of the casting grooves and the anchor tension bars in the grooves, when pouring concrete into the casting grooves on the end faces of the first wall body, the second wall body and the third wall body and on the side faces of the load-bearing column, the concrete can fully fill the building grooves and be tightly combined with the anchor tension bars, thereby greatly improving the connection strength between the wall body and the load-bearing column and effectively preventing problems such as cracks caused by insecure connection.

[0014] 3. Fixing decorative parts at the joint positions on the outer side faces of the first wall body and the second wall body not only beautifies the appearance of the building but also effectively covers the defects at the joints, improving the overall aesthetic degree.
