A BLAST-RESISTANT STRUCTURE

摘要

A blast-resistant structure comprising a body in which is defined an aperture is disclosed. The aperture is bounded by two edge parts of the 5 body. The blast-resistant structure further comprises a door configured selectively to close-off the aperture, and first and second securing mechanisms configured selectively to secure the door to respective ones of the body edge parts. Each securing mechanism comprises a locking channel associated with the body and a corresponding locking pin 10 associated with the door. Each locking pin is moveable between an open position in which the locking pin is external to the locking channel and a secured position in which the locking pin is engaged in the locking channel. The locking channel has a generally rectangular cross-section that is defined on at least first and second sides by a locking pin retention 15 part. Furthermore, the locking pin retention parts and the locking pins are formed of sheet material.
