In order to control the position of the drawknot in the sandwich insulation wallboard, a positioning steel bar 204 is arranged at a position of the horizontal portion 202 close to the vertical portion 201, and the positioning steel bar 204 is preferably arranged vertically. The specific location of spacer bar 204 may be determined based on the thickness of insulation board 20 and outer leaf wall board 30, for example, spacer bar 204 may be positioned such that the drawknot is positioned 30mm deep in outer leaf wall board 30.
