Abstract

A wall for a building that includes a framed wall structure including a top support, a bottom support, and opposing side supports connected together, and at least one intermediate support attached to the top support and the bottom support, and a blast panel made of a cementitious material attached to the framed wall structure.

First claim

The invention claimed is:

1. A wall for a building, comprising:
a framed wall structure including a top support, a bottom support, and opposing side supports connected together, and at least one intermediate support attached to said top support and said bottom support; and
a blast panel including a core comprised of a cementitious material including fiberglass fibers attached to said framed wall structure, said core including a first surface that is attached to said framed wall structure and a second, opposing surface that is an exposed surface devoid of any reinforcing structure,
wherein said blast panel is configured to withstand forces up to 10 psi/89 psi-ms.

2. The wall of claim 1 , wherein said cementitious material is a cement-gypsum binder including alkali-resistant fiberglass fibers.

3. The wall of claim 1 , further comprising a plurality of said blast panels attached to said framed wall structure.

4. The wall of claim 1 , further comprising a plurality of said blast panels attached to opposing sides of said framed wall structure.

5. The wall of claim 1 , further comprising a plurality of said blast panels attached to a first side of said framed wall structure, and a plurality of wallboard panels attached to a second, opposing side of said framed wall structure.

6. The wall of claim 1 , further comprising a plurality of said blast panels attached to said framed wall structure, and at least one of said blast panels attached to said plurality of said blast panels.

7. The wall of claim 1 , further comprising a first plurality of said blast panels attached to said framed wall structure, and a second plurality of said blast panels attached to said first plurality of said blast panels.

8. The wall of claim 1 , further comprising at least one finishing material attached to said blast panel.

9. The wall of claim 8 , wherein said finishing material includes at least one of: an adhesive, an insulating material, a mesh material and a plaster material.

10. A modular assembly for a building, the modular assembly comprising:
a plurality of framed wall structures secured to each other, each of said framed wall structures including a top support, a bottom support, and opposing side supports connected together and at least one intermediate support attached to said top support and said bottom support; and
a blast panel including a core comprised of a cementitious material including fiberglass fibers attached to at least one of said plurality of framed wall structures, said core including a first surface that is attached to said at least one of said plurality of framed wall structures and an second opposing surface that is an exposed surface devoid of any reinforcing structure,
wherein said blast panel is configured to withstand forces up to 10 psi/89 psi-ms.

11. The modular assembly of claim 10 , further comprising a plurality of said blast panels attached to a first side of each of said framed wall structures.

12. The modular assembly of claim 10 , further comprising at least one blast panel attached to each of said plurality of framed wall structures.

13. The modular assembly of claim 11 , wherein said cementitious material is a cement-gypsum binder including alkali-resistant fiberglass fibers.

14. The modular assembly of claim 11 , further comprising a plurality of said blast panels attached to a second side of each of said framed wall structures.

15. The modular assembly of claim 11 , further comprising a plurality of wallboard panels attached to a second side of each of said framed wall structures.
