Abstract

The present invention provides an energy absorber for a blast barrier system comprising a substantially tubular member extending longitudinally along an axis from a first end portion to a second end portion, each of the first end portion and the second end portion having a substantially similar geometric, profile, wherein the energy absorber collapses under a predetermined load when compressed by a residual blast force. The energy absorber of the present invention may help minimize damage to people and structures by further dissipating force from a blast in a blast barrier system.

First claim

What is claimed is:

1 . A blast barrier system comprising:
a blast panel; a beam; an energy absorber comprising a substantially tubular member extending longitudinally along an axis from a first end portion to a second end portion, each of the first end portion and the second end portion having a substantially similar geometric profile; wherein the blast panel flexes when compressed by a blast force, and wherein the energy absorber collapses under a predetermined load when compressed by a residual blast force.

2 . The blast barrier system according to claim 1 , wherein the blast panel comprises a thermoplastic polymer.

3 . The blast barrier system according to claim 2 , wherein the thermoplastic polymer is polycarbonate.

4 . The blast barrier system according to claim 3 , wherein the blast panel comprises two layers of polycarbonate.

5 . The blast barrier system according to claim 4 , wherein the two polycarbonate layers are held together with aliphatic thermoplastic polyurethane.

6 . The blast barrier system according to claim 1 , wherein the blast panel comprises glass.

7 . The blast barrier system according to claim 2 , wherein the blast panel is glass clad.

8 . The blast barrier system according to claim 7 , wherein the blast panel has one or more bolt holes placed.

9 . The blast barrier system according to claim 7 , wherein the glass cladding does not have one or more bolt holes therethrough.

10 . The blast barrier system according to claim 1 , wherein the energy absorber extends substantially longitudinally along a face of the structure.

11 . The blast barrier system according to claim 1 , wherein the energy absorber extends substantially horizontally along a face of the structure.

12 . The blast barrier system according to claim 1 , wherein the geometric profile of the energy absorber is selected from the group consisting of hexagonal, square, circular and oval.

13 . The blast barrier system according to claim 1 , wherein the absorber is filled with an energy-absorbing foam.

14 . The energy absorber according to claim 1 , wherein the absorber is filled with an energy-absorbing malleable metal insert.

15 . The blast barrier system according to claim 1 , wherein the absorber is made from a metal.

16 . The blast barrier system according to claim 15 , wherein the metal is selected from the group consisting of steel, aluminum and aluminum alloys.

17 . The blast barrier system according to claim 1 , wherein the beam is made from a metal.

18 . The blast barrier system according to claim 17 , wherein the metal is selected from the group consisting of steel, aluminum and aluminum alloys.

19 . The blast barrier system according to claim 1 , wherein the blast panel is attached to the beam.

20 . The blast barrier system according to claim 1 , wherein the energy absorber is attached to a structure,

21 . The blast barrier system according to claim 1 , further comprising a strut.

22 . The blast barrier system according to claim 21 , wherein the strut is attached to the beam.

23 . The blast barrier system according to claim 21 , wherein the strut is attached to the energy absorber.

24 . The blast barrier system according to claim 21 , wherein the strut is made from a metal.

25 . The blast barrier system according to claim 24 , wherein the metal is selected from the group consisting of steel, aluminum and aluminum alloys.
