SYNTHETIC RESIN-MADE WASHER

摘要

PROBLEM TO BE SOLVED: To prevent the reduction of thermal insulation performance of a thermal insulation wall due to heat transfer through a screw when fixing a thermal insulation material on a structural member such as a wall panel by the screw. SOLUTION: This synthetic resin-made washer 1 is used to fix by the screw 4. The washer 1 is composed of a washer main body 5 and a cap body 6, and they are integrally connected through a hinge 9. The washer main body 5 is formed into a bowl shape provided with a recessed part 7 storing a head part 4a of the screw 4 completely, and the cap body 6 is fitted into the inside of the recessed part 7. Since it is possible to prevent the head part 4a of the screw 4 from being exposed to the outdoor by the cap body 6, heat transfer to the inside and the outside of a building through the screw 4 is prevented or suppressed.
