An explosion venting wall structure incorporating a releasable fastener means. The fastener means comprises a fastener member having a substantially circular body with an opening therethrough, and at least two offset arms extended radially outward from said tubular body. The fastener member circular body is adapted to be disposed in a circular opening in a wall structure, with the offset arms overlapping the opening edge and seated against the wall surface, and with a screw or other retainer means provided for extension through the circular body opening and through said opening in the wall and into securing engagement with a building structural support member. The offset arms are adapted to be folded over or collapsed simultaneously by explosion or windload pressures exerted on the wall structure to permit said circular body with its folded over arms to be passed through said opening in the wall structure and allow the wall structure to be separated from the building structural support member and fall to the ground.

In a building structure, the combination comprising: a. a fixed building structure having an opening in the exterior of the building; b. a releasable venting wall panel for enclosing said opening in the fixed building structure and being provided with a plurality of attachment holes; c. a plurality of releasable fastener means solely attaching said releasable venting wall panel to said fixed building structure and including; b. a fastener member disposed at each of said holes in said releasable venting wall panel on the exterior side thereof and having arm means extending radially outward and overlapping the exterior edge of the adjacent hole; and, b. retainer means for each of said fastener members extended through the adjacent hole in the releasable venting wall panel and attached to the fixed building structure, whereby when an internal explosion occurs inside the fixed building structure and generates a predetermined force of the releasable wall venting panel, the releasable venting wall paner will be forced outward away from the fixed building structure and the arm means on all of the fastener member will be folded over simultaneously to permit each fastener member to pass through the adjacent hole in the releasable venting wall panel and completely detach the releasable venting wall panel from the fixed building structure.
