Abstract:
1. A blast-proof window and mullion system for sustaining and mitigating an explosion and/or blast to said window and mullion system on a structure, comprising: a) a blast-resistant mullion including a mullion housing having mullion walls with outer surfaces; b) a pressure bar member including a pressure bar housing having an interior wall and a pair of outer walls being connected to said interior wall to form a channel opening; said outer walls being angled relative to each other for reducing the space between said angled walls and for reducing the size of said channel opening for reduction of bullet and/or blast penetration to said interior wall of said pressure bar member; c) a cover for overlapping said angled outer walls and for protecting said pressure bar member; d) a plurality of laminated shatter-proof and bullet-proof windows connected to said mullion housing and said pressure bar housing; e) one of said mullion walls of said mullion housing including a mullion tongue thereon having a pair of tongue extension arms for forming a vertical bolt receiving channel therebetween; f) each of said tongue extension arms having interior serrated surfaces for receiving threaded bolts between said interior serrated surfaces; g) said interior wall of said pressure bar member having a pair of spaced-apart pressure bar extension arms thereon; h) each of said pressure bar extension arms have exterior and interior serrated surfaces thereon for receiving structural adhesive thereon; and i) said interior wall of said pressure bar member including a plurality of spaced-apart bolt openings for receiving a plurality of said threaded bolts therein for permanently locking together said pressure bar extension arms with said mullion extension arms in order to join together and lock said pressure bar housing of said pressure bar member to said mullion housing of said blast-resistant mullion to form said blast-proof window and mullion system.
