JPS6448954A - Structure receiving dew condensation in wall - Google Patents

Abstract

PURPOSE: To prevent the occurrence of corrosion of a wall body by a method wherein inner and outer moistureproof layer are formed between a heat insulation material and an inner plate, and a waterproof dew receiving part is arranged in a watertight manner together with the inner moistureproof layer at the lower end part of a heat insulating material surrounded with an outer plate, a lower frame, and the outer moistureproof layer. CONSTITUTION: In a wall body wherein a space formed with an outer plate 1, an inner plate 2, an upper frame 3, and a lower frame 4 is filled with a heat insulation material 7, and inner and outer moistureproof layers 8 and 9 formed of a synthetic resin sheet are formed between the heat insulating material 7 and the inner plate 2. Further, a dew receiving part 10 having a watertight waterproof function together with the inner moistureproof layer 8 is formed at the lower end part of the heat insulation material 7 surrounded with the outer plate 1, the lower frame 4, and the outer moistureproof layer 9. This constitution prevents penetration of indoor moisture in a wall body by the inner and outer moistureproof layers 8 and 9 and further, since condensate generated at the interior of the wall body is gradually discharged from a condensate receiving part 10 at the lower end of the heat insulation material 7 through the outer plate 1, corrosion of a wall body is prevented from occurring.
