The surface where the hypotenuse of the corner template 10 is located is fitted with the connecting plane 21, and the positive corner template 10 cooperates with the two adjacent positive corner connecting templates 2 to form the positive corner of the wall 300; the negative corner template 3 is a cylinder with a right-angled triangle cross-section and an internal cavity, and the two hypotenuses of the negative corner template 3 are respectively fitted and connected with the side edges of the first vertical templates 11 of the two adjacent wall column templates 1, and a gap 34 is opened in the middle of the surface where the hypotenuse of the negative corner template 3 is located, and the end faces of the two ends of the negative corner template 3 are respectively spaced apart with negative corner through holes 35.
