Airtight structure

Abstract

Abstract PURPOSE:To increase the airtight performance of an airtight structure, and prevent any gs leakage of the structure by integrating packings and a stacked body togehter by interposing a heat-resistant cold-setting adhesive between them. CONSTITUTION:Since a stacked body is stuck to a reinforcing plate 2 and ?-shaped packings 3 and 30 by means of a monoliquid-type silicone adhesive, any asymmetric laminated structure which might be developed at the corners is prevented by the packing of the adhesive. Although leaks develop due to the asymmetric laminated structure when the packings 3 and 30 are only tightly pressed upon the stacked body and the reinforcing plate 2, the influence of the asymmetric laminated structure which is the cause of leak generation is extremely minimized by unifyingly sticking the packings 3 and 30 to the stacked body by means of the adhesive in such a manner as above. Here, packings 3 and 30 may be unified into a ?-shaped packings, or bar-like packings 30 may stuck to the peripheral parts of L-shaped packings 3 which are installed at the corners.
