Autoclaved aerated concrete wallboard through-wall hole expansion bolt sinking type process method

The invention provides an autoclaved aerated concrete wallboard through-wall hole expansion bolt sinking type process method. The process method comprises the following steps that S1, firstly, a position where a supporting facility needs to be installed is accurately positioned by using a measuring tool, and an accurate punching position is marked; S2, an expansion bolt of a matched specificationis further selected, and then an electric hammer is adopted to be aligned with the punching position to drill the through-wall hole; S3, the expansion bolt is implanted into the wall face of the otherside of a wall body and sinks into the wall face of the other side by 15 mm; S4, the expansion bolt is fastened to the length needed by facility installation; and S5, water is added into an anti-cracking agent prepared from a polymer emulsion and an additive, cement and sand according to a certain ratio, and stirring is performed to prepare anti-cracking mortar which can meet certain deformationand keep non-cracking; and
