The membrane which forms the pulling tearing propagation prevention structural null film structural building

摘要

PROBLEM TO BE SOLVED: To provide a tear propagation prevention structure of a membrane body so as to prevent the propagation of tears from widely spreading the tears even if the tears occur in the membrane body constituting a membrane structural building.;SOLUTION: The tear propagation prevention structure is so constituted that tapes 3 with high strength are stuck on the membrane body 1 constituting a membrane structural building. It is so constituted that the tape 3 with high tension is held between membrane materials 1a and 1a of a weld metal zone welding the membrane materials 1a and 1a to each other for constituting the membrane body 1 and that the membrane body 1 and tape 3 are integrally formed.;COPYRIGHT: (C)2001,JPO
