Aus Kunstharzfilmen aufgebaute Druckluft-Schichtkoerper und Verfahren zu ihrer Herstellung

摘要

Disclosed herein is a pneumatic shell structure which is constructed from two sheet layers, each composed of a plurality of long rectangular synthetic resin films which are arranged side by side in a manner that longitudinal side edge portions of the films are mutually superimposed. The sheet layers are hermetically sealed about their edges to a support frame, so that the arranged films can uniformly carry the stress created on the sheet layers owing to the inner pressure of the airtight air chamber.
