A shelter system having an erecting frame system and a protective skin system. The erecting frame system has at least two A-frame legs and at least one tensioning element. The A-frame legs each comprise at least one elongated structural member, each of the A-frame legs coalescing with at least one other A-frame leg with at least one connection. The tensioning element is at least temporarily affixed to a free end of each of the at least two A-frame legs, and comprises at least one elongated structural element capable of generating a tension force to draw the free ends of the A-frame legs towards one another, thereby at least temporarily lifting the connection to a predetermined height above the free end of each A-frame leg. A protective skin system is also provided with at least one side plane, one roof plane, and one end plane. The side plane is disposed between two A-frame legs; the roof plane is concordant with the ground surface; and the end plane is disposed between two A-frame legs of a constituent A-frame leg pair and a ground surface. The planar element of the protective skin system provides at least a partial barrier from a ballistic threat to a volume behind the planar element, the loading of the protective skin system being transferred at least in part first to the erecting frame system and ultimately to the ground surface.

A system of modular components for on-site assembly of a shelter for an above-ground structure to protect the structure from blast, wind, fire or other physical hazards. A pyramidal shelter with triangular or rectangular base is formed by joining side panels to each other. Each side panel includes a triangular frame covered, except at access hatch, observation port and door openings, with either steel plate or diamond steel mesh to which blast-resistant, fire-resistant or other kinds of coatings or panels are applied. A corner anchor assembly to support each corner of a shelter has a lower plate, an overlying split plate, and a pair of upstanding, anchor rods attached to the split plates for insertion into hollow, lower portions of side beams of adjacent side panels. The corner anchor assemblies facilitate expansion of an assembled shelter by addition of more modular components.

An impact resistant exterior sheathing gypsum building panel with an integrated impact resistant woven mesh which protects against impact from projectiles such as those conveyed by hurricane force winds is provided. Methods for manufacturing these exterior sheathing gypsum building panels with an integrated impact resistant woven mesh are also provided. An exterior sheathing system employing the exterior sheathing cementitious building panel is provided.

This disclosure relates to systems, methods, and apparatuses for providing security at sites to protect against active shooter situations and other dangerous threats. In certain embodiments, a security system comprises one or more security boxes that are in communication with an electronic security platform. The security boxes house equipment that can be utilized by individuals to protect themselves against security threats and to secure their immediate location. The security boxes also include various electronic components that enable detecting security threats and communicating with the electronic security platform.

Enclosed structures, such as guard towers, are provided which are designed to be easily transportable, constructed easily onsite and erected in a manner which produces an exceptionally blast resistant structure that is also advantageously designed for positioning within a perimeter wall. In particular, in some embodiments, the guard towers have a pentagon shape and are comprised of a plurality of composite panels. Each panel is able to be constructed onsite. The panels typically have a rectangular shape with at least one half of the panel constructed as a solid composite of concrete and metal. Once the panels are constructed, the panels are erected and arranged in a pentagon shape. The panels are bolted together with the use of vertical face connections. These connections provide better structural integrity, retained over time, particularly after subjection to a blast. In addition, the pentagon shape provides improved safety when positioned along a perimeter wall.

In one embodiment, a flashing system is provided for fortifying seams between a first blast, ballistic, and forced entry resistant shelter module and a second blast, ballistic, and forced entry resistant shelter module. The system includes a first side flashing assembly for fortifying a first side seam between the first blast, ballistic, and forced entry resistant shelter module and the second blast, ballistic, and forced entry resistant shelter module, a top flashing assembly for fortifying a top seam between the first blast, ballistic, and forced entry resistant shelter module and the second blast, ballistic, and forced entry resistant shelter module, and a second side flashing assembly for fortifying a second side seam between the first blast, ballistic, and forced entry resistant shelter module and the second blast, ballistic, and forced entry resistant shelter module. The system can also include fastening assemblies for coupling the flashing assemblies with the blast, ballistic, and forced entry resistant shelter modules.

The modular anti-ballistic shelter system includes two end units and, optionally, additional middle units for a wider structure. End and middle units may also stack atop each other for multi-story structures. Each unit is configured to comply with both ISO standards for size and weight, and with the U.S. Department of State Certification Standard for Forced Entry and Ballistic Resistance of Structural Systems. Each exterior wall of each end unit and each middle unit is reinforced with wall studs that penetrate the unit's structural framework of beams and frames. Even though these wall studs are welded into place, penetration of the wall studs into the beams and frames ensures acceptable blast, ballistic, and forced entry resistance even if the welds are flawed.
