圧して接着していた（第６図）。(b) Conventional technology In recent years, in the construction of condominiums, etc., especially on the base of building walls,
An insulating board that integrates hard surface material and plastic foam is attached to the base of the wall of a building made of reinforced concrete (RC construction) or precast concrete construction (PC construction) using a high-viscosity adhesive (mainly an inorganic adhesive such as gypsum adhesive). Construction method (dry method 1 method/GL
construction method) is commonly practiced. This construction method also serves to adjust the unevenness (unevenness of the wall surface) and slump (deviation of the wall surface from the vertical plane) of the ground beneath the wall of the building. Depending on the unevenness of the wall surface, the adhesive was applied in different amounts and heights, and then a heat insulating board was pressed and adhered to it (Figure 6).

露を原因とするカビの発生という問題点があった。(c) Problems to be solved by this invention When a high viscosity adhesive such as a gypsum adhesive is partially used to bond the base of a building wall and a heat insulating board, the insulating wall becomes thicker than the high viscosity adhesive. This created a gap between the building wall base and the insulation board surface. As a result, air convection occurs between the floor and ceiling through this gap due to the temperature difference, which tends to cause condensation on the ground beneath the building walls (especially in cold regions like Hokkaido). There was a problem with the growth of mold.

によって、上述の問題点を解決する。(b) Means for solving the problem This invention is a method of constructing a heat insulating wall in which a heat insulating wall is formed by bonding a heat insulating board to the base ground of a wall of a building made of reinforced concrete, etc. The present invention relates to a method for constructing a heat insulating wall, in which a heat insulating board is formed with holes punched at appropriate positions. After temporarily fixing it facing the base of the building wall, foam adhesive is injected into the gap between the base of the building wall and the insulation board through the hole, and it hardens to bond the base of the building wall and the insulation board. The above-mentioned problems are solved by proposing a construction method for a heat-insulating wall characterized by adhesive bonding.
