In one embodiment, a frame and stair system for engaging a wall includes multiple pad assemblies, a distal frame assembly, a lower proximal frame assembly, an upper proximal frame assembly, multiple stair assemblies, and multiple upper panel stair adapter brackets. A lower stair assembly is coupled with a left stair pad assembly, a right stair pad assembly, a left distal leveling pad, and a right distal leveling pad. A middle stair assembly is coupled with the distal frame assembly and the upper proximal frame assembly. An upper stair assembly is coupled with the upper proximal frame assembly. The upper proximal frame assembly is coupled with the lower proximal frame assembly. A left upper panel stair adapter bracket and a right upper panel stair adapter bracket are coupled with the upper stair assembly and are configured to engage an upper edge of the wall.

Frame and stair systems and methods

An easily assembled, transportable, re-deployable, modular, protective, double-roof system is disclosed which is compatible with other Modular Protective System (MPS) components and can be assembled in a variety of configurations to provide soldiers and equipment with protective enclosures.

Transportable modular system for covered isolation of assets

A configuration, all components of which are man portable in some embodiments, for holding panels to protect assets against external force and impacts from airborne projectiles. An open box-like stackable frame module holds panels along a side of the frame. Multiple frames are connected to construct a protective barrier, such as a wall. Frames include provisions for connection in a vertical configuration so as to allow stacking of the frames to increase the height of the barrier. A method of installing is also provided.

Transportable modular configuration for holding panels

A cementitious armor panel assembly including cementitious armor panel with ballistic and blast resistant properties attached to a frame structure to produce a protective structure. The cementitious armor panels have a continuous phase resulting from the curing of an aqueous mixture of an inorganic cement binder, an inorganic mineral filler having a particle size of about 150-450 microns, a pozzolanic mineral filler, a polycarboxylate based superplasticizer self-leveling agent, and water. The mixture may also contain alkanolamine, and acid or acid salt. Prior to curing, the continuous phase is reinforced with fiber uniformly distributed in the continuous phase before it is cured to form the panel. The panel may be reinforced with a skin attached to at least one surface of the panel.

Cement based armor panel system

A cementitious panel with ballistic and blast resistant properties having a core layer of ultra-high compressive strength composite and at least one skin layer. The panels can also be used in walls, ceiling and flooring panels which require high compressive strength for resistance to earthquakes and surfaces resistant to surface abuse such as in prison and other institutions. The panel core layer has a continuous cementitious phase resulting from the curing of an aqueous mixture, in the absence of silica flour, of inorganic cement binder, inorganic mineral filler having a particle size of about 150-450 microns, a pozzolanic mineral filler, polycarboxylate based superplasticizer, alkanolamine and acid or alkali metal acid salt; and water. The mixture may be uniformly reinforced with fiber added before curing. The cementitious core layer is then reinforced with the skin, such as fiber reinforced polymer, attached to at least one panel surface.

Cement based laminated armor panels

A self-leveling cementitious mixture with excellent flow properties and which hardens with a controlled rate of strength development to an ultra-high compressive strength composite composition for use in making articles such as cementitious armor panel with ballistic and blast resistant properties including: a continuous phase resulting from the curing of an aqueous mixture, in the absence of silica flour, of inorganic cement binder, inorganic mineral filler having a particle size of about 150-450 microns, pozzolanic mineral filler, polycarboxylate based self-leveling agent and water. The cementitious mixture may include alkanolamine, such as triethanolamine, and acid or acid salt, such as tartaric acid. The cementitious composition may be reinforced with reinforcing fibers, e.g. glass fibers, in an amount of about 0.5-6.0% by volume of the overall cementitious composition. The fibers are uniformly dispersed in the cementitious composition before it is cured to form a final cementitious armor panel.
