Double insulation structure of building exterior wall and construction method

摘要

The present invention relates to a method of constructing double insulation after completing the outer wall of the foundation concrete of a building and its construction structure.More specifically, a contact insulation is first installed on the outer concrete wall of the building, and then the anchor while penetrating the contact insulation. After installing the bolts on the concrete wall, fix the fixing hardware using anchor bolts, laminate the insulation finishing material in which insulation and stone are integrated on the top of the fixing hardware, and fix the fixing hardware again on the top of the insulation finishing material. This is a method of fixing the direct-connected piece so that it penetrates the insert reinforcement bonded to the insulation finishing material using the fixing hole of the hardware. It is possible to improve the insulation efficiency and obtain a solid construction state while reducing construction time and manpower, while obtaining a high heat transmission rate. It is characterized by being able to.
