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. |

1. A modular system for on-site assembly of a shelter and attachment of the shelter to a ground surface, comprising:
three or more factory-preassembled, triangular side panels, each of said triangular side panels being of equal size and including a triangular, panel frame, said triangular, panel frame comprising a rigid first side beam, a rigid second side beam, and a rigid base beam, the first and second side beams having upper ends joined at an apex of said triangular, panel frame and the base beam extending between, and joined to, opposite, lower end portions of the first and second side beams; coupling means attached to the first and second side beams for attaching in mating engagement parallel, side by side alignment a first side beam of said triangular, panel frame to a second side beam of a triangular, panel frame of any other triangular side panel of said system; and covering means partially or fully covering at least one side of said triangular panel frame; anchor means reversibly attachable to a lower end portion of each of said triangular side panels for securing a triangular side panel to the ground at a location selected for on-site assembly of the shelter, said anchor means including a corner anchor assembly for each corner of said shelter after said shelter has been assembled, said corner anchor assembly including a lower anchor plate having an upper surface and an opposite, lower surface; a split, upper anchor plate comprising a first upper plate and a second upper plate in coplanar, side by side relation; wherein the lower anchor plate and the first upper plate and the second upper plate each have a plurality of rebar apertures disposed and dimensioned for insertion of rebar therethrough; fastener means for reversibly attaching the first and/or second upper plates to an upper surface of the lower anchor plate; and telescopically adjustable means attached to, and extending upward and away from, the first upper plate and/or the second upper plate for reversibly attaching either one or both of the first and second upper plates to a lower end of a first or second side beam; and wherein, once said modular system has been assembled at said location to form a shelter and has been attached to said ground surface by rebar driven into the ground through said rebar apertures of each corner anchor assembly, and the first and second upper anchor plates of each corner anchor assembly overlie, rest upon, and are attached by said fastener means to the lower anchor plate of said each corner anchor assembly and are attached by the telescopically adjustable means to a lower end of a first or second side beam, either of the first or second upper anchor plates of each corner anchor assembly can be detached from the lower anchor plate thereof to facilitate removal of a side panel from the shelter and attachment of additional side panels to the shelter and thereby expand the size of the shelter. |
