The present anti-ballistic shelter is a reinforced unit 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 end and side wall of the unit is reinforced with wall studs that penetrate the unit's structural framework. Even though these wail studs are welded into place, penetration of the wall studs into the framework ensures acceptable blast, ballistic, and forced entry resistance even if the welds are flawed.

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.

A steel wall stud has a rear wall, two parallel side walls, each side wall having a front end wall that projects away from interior cavity formed by the rear and side walls.

A metallic extruded profile has two parallel skins interconnected by a set of at least two webs running between extrusion edges of the profile and snap-fit features on joining edges permitting two instances of the profile to snap fit together along the joining edges, where a first web that is closest to snap-fit features of a first joining edge, is a curved web viewed from the extrusion edges. The curvature allows for both the curved web and skins to participate in snap-fit deformation, allowing for the deformation to be distributed over a large area, for a stiffer snap fit, and reduced plastic deformation.

The present invention includes a lintel support to aid in lintel repair and/or reinforcement. The lintel support has a body with a top, a bottom, and a height extending therebetween; at least one claw at the top; and a bracket at the bottom. In use, points are dug out of a mortar line above the lintel and the claws of the lintel support are positioned into those points. With the claws so positioned, the bracket will be below the failing lintel. A support beam is placed under the bracket and a jack lift provides uplift at the mortar line where the claws are positioned.

The invention describes a girder profile made of stone material and tensile-resistant material, which is preferably made of 002 in order to fix greenhouse gases. This is intended to replace steel girders and aluminum girders with sustainable building materials.

The invention adopts the principle of dovetailing from timber construction and transfers this principle to the structure made of stone material and fiber material, in that the planes of the profile, which usually meet orthogonally, overlap geometrically with regard to the tension-stable material parts or at least meet in one cutting plane.

Such materials made of mineral substances and fibrous materials are significantly lighter, more durable and more ecological than such carriers made of metallic materials.
