Blast resistant glass block panel
A glass block panel assembled, framed and attached to a substrate such that it resists the shock wave resulting from a blast event.
1. A blast-resistant glass block panel comprising:
a plurality of glass blocks arranged in a panel, wherein each glass block comprises a front face, a rear face, and four side walls, wherein said side walls possess a concave profile, further wherein said side walls include a protrusion that runs around the perimeter of said glass block parallel to said front face and said rear face, wherein a notch is located at the center of each side wall, each block forming a space with an adjacent block in said panel;
a rigid spacer placed in each said respective space, wherein said rigid spacers possess a convex shape that substantially corresponds the concave profile of said glass block, further wherein said spacers include a notch at the center of said spacer;
a perimeter channel disposed around a perimeter of the panel, wherein the perimeter channel has front and rear legs that extend over portions of the front and rear faces, respectively, of each said glass block defining the perimeter of the panel;
a two-piece channel disposed around said perimeter channel, wherein said two-piece channel includes a primary channel member which is adapted to be attached to a frame, and a secondary channel member which is attachable to the primary channel member, wherein the two-piece channel has front and rear legs that extend over and past the front and rear legs of the perimeter channel on said glass blocks on the perimeter of said panel; and
sealant placed between each of said plurality of glass block and said rigid spacers.
2. The blast-resistant glass block panel of claim 1 , wherein each of said glass block possesses a front face and a rear face having a thickness of at least ¾ inch.
3. The blast-resistant glass block panel of claim 1 , wherein said rigid spacers are adapted to provide a consistent spacing between said glass block.
4. The blast-resistant glass block panel of claim 1 , wherein said rigid spacers are plastic.
5. The blast-resistant glass block panel of claim 4 , wherein said plastic is vinyl.
6. The blast-resistant glass block panel of claim 1 , wherein said perimeter channel is plastic.
7. The blast-resistant glass block panel of claim 1 , wherein said two-piece channel is metal.
8. The blast-resistant glass block panel of claim 7 , wherein said metal is aluminum or an aluminum alloy.
9. The blast-resistant glass block panel of claim 1 , wherein said sealant is silicone.
10. The blast-resistant glass block panel of claim 9 , wherein said silicone is a structural silicone.
