The heat-insulating wall board is a foamed concrete heat-insulating wall board, after the heat-insulating wall board is stuck to the drilled hole of the wall body, firstly spraying rock-soil solidifying agent slurry to the outer section and periphery of the drilled hole, and then implanting anchor bolts. The front end of the screwdriver head 4 is a control rod type hexagonal screwdriver head, and the leveling by mortar is the leveling by thermal insulation mortar.

As shown in fig. 1, the steps are in sequence: the heat-insulating wall board is attached to the wall body; drilling; implanting an anchor bolt; screwing the anchor bolt into the anchor bolt pipe by using the bit of the special drill bit; drilling a screw anchor bolt deeply by using a special drill bit, simultaneously drilling a circular groove hole on the thermal insulation wallboard by using a special drill hole-opening circular barrel, and compressing the inner circle part of the circular groove hole to form a thermal insulation wallboard pit until the positioning disc is close to or attached to the thermal insulation wallboard when a flange disc at the rear end of the anchor bolt is deep; plugging a pipe orifice at the rear end of the anchor bolt by using an end cap; and (5) leveling the pit of the heat-insulating wall plate with the flange at the rear end of the exposed anchor bolt by using mortar.

As shown in fig. 2, the steps may also be, in order: the heat-insulating wall board is attached to the wall body; drilling; spraying rock soil solidifying agent slurry to the outer section and the periphery of the drilled hole; implanting an anchor bolt; screwing the anchor bolt into the anchor bolt pipe by using the bit of the special drill bit; drilling a screw anchor bolt deeply by using a special drill bit, simultaneously drilling a circular groove hole on the thermal insulation wallboard by using a special drill hole-opening circular barrel, and compressing the inner circle part of the circular groove hole to form a thermal insulation wallboard pit until the positioning disc is close to or attached to the thermal insulation wallboard when a flange disc at the rear end of the anchor bolt is deep; plugging a pipe orifice at the rear end of the anchor bolt by using an end cap; and (5) leveling the pit of the heat-insulating wall plate with the flange at the rear end of the exposed anchor bolt by using mortar.

As shown in fig. 3, the steps may further be in sequence: the heat-insulating wall board is attached to the wall body; drilling; spraying rock soil solidifying agent slurry to the outer section and the periphery of the drilled hole; the periphery of the anchor bolt rod body is coated with sealing glue or slurry of cement-based joint filling slurry is poured into the inner section of the drill hole; implanting an anchor bolt; screwing the anchor bolt into the anchor bolt pipe by using the bit of the special drill bit; drilling a screw anchor bolt deeply by using a special drill bit, simultaneously drilling a circular groove hole on the thermal insulation wallboard by using a special drill hole-opening circular barrel, and compressing the inner circle part of the circular groove hole to form a thermal insulation wallboard pit until the positioning disc is close to or attached to the thermal insulation wallboard when a flange disc at the rear end of the anchor bolt is deep; plugging a pipe orifice at the rear end of the anchor bolt by using an end cap; and (5) leveling the pit of the heat-insulating wall plate with the flange at the rear end of the exposed anchor bolt by using mortar.

By adopting the technical scheme, the method for installing and supervising the fixing anchor bolt of the outer wall heat-insulating layer has the advantages of simple and standard installation and supervision, good firmness, capability of ensuring that the anchor bolt is installed in place and strong reliability.
