step five: the combined body of the insulation board and the outer support frame is hoisted integrally by a crane, and the hoisting piece is used as a hanging hook hanging point of the crane until the combined body of the insulation board and the outer support frame is hoisted to the outer side of the construction area of the cast-in-place concrete wall body integrally;
step six: adjusting the position of a combination body of the heat-insulation board and an outer support frame, enabling the heat-insulation board to be abutted against a reinforcement cage in a construction area of a cast-in-place concrete wall body through a cushion block, coaxially punching an inner template and the heat-insulation board through a bolt penetrating connection hole preset on a support frame by using an electric drill, inserting a wall penetrating bolt fastener into the hole, and fastening and connecting the inner support frame, the inner template, the reinforcement cage in the construction area of the cast-in-place concrete wall body, the heat-insulation board and the outer support frame into an integrated structure through the wall penetrating bolt fastener;
step seven: repeating the first step to the sixth step until the construction of the integrated structures in all the areas is completed, and fixedly connecting the support frames in the adjacent integrated structures through bolt fasteners between the supports;
step eight: and pouring concrete into the construction area of the cast-in-place concrete wall body until the concrete is solidified to form the cast-in-place concrete wall body, completely loosening the wall-penetrating bolt fastener, the heat-insulating support fastener and the bolt fastener between supports, and completely removing the inner template, the inner support frame assembly and the outer support frame.
9. The construction method of the external thermal insulation support integrated structure of the building enclosure wall of claim 2, when the building enclosure wall is a currently built wall, is characterized by comprising the following steps:
the method comprises the following steps: the insulation board and the support frame are tiled and stacked together, then vertical punching is carried out on the insulation board through a bolt penetrating connection hole preset on the support frame by using an electric drill, then an insulation support fastener is inserted into the hole, the insulation board and the support frame are fixedly connected together by the insulation support fastener, and an anchor disc of the insulation support fastener is flush with the inner surface of the insulation board;
step two: vertically punching a heat insulation plate in a grid area of a support frame by using an electric drill, then inserting a heat insulation wall fastening piece into the hole, wherein an anchor disc of the heat insulation wall fastening piece is flush with the outer surface of the heat insulation plate, and a rod body of the heat insulation wall fastening piece extends out of the inner surface of the heat insulation plate;
step three: the combined body of the insulation board and the support frame is hoisted integrally by a crane, and the hoisting piece is used as a hanging hook hanging point of the crane until the combined body of the insulation board and the support frame is hoisted integrally to the outer side of the construction area of the existing masonry wall;
step four: coating an adhesive on the inner surface of the heat insulation plate, and then starting building of the existing built wall, wherein in the building process of the wall, the building blocks need to be tightly bonded with the adhesive on the inner surface of the heat insulation plate, and a fastener rod body of the heat insulation wall extending out of the inner surface of the heat insulation plate needs to be embedded into an ash gap between the building blocks;
step five: and after the masonry of the existing masonry wall is finished, loosening the heat-preservation support fastener, and then removing the support frame.
