A modular system for on-site assembly of a shelter and attachment of the shelter to a ground surface, comprising:
- three or more 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 second side beam, and a base beam, the first and second side beams having upper ends joined at an apex of the 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 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 modular system;
- 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 triangular side panel 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, said corner anchor assembly including
- a lower anchor plate;
- a split, upper anchor plate comprising a first and second upper plate in side by side, coplanar 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 second upper plates to 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 upper plate and/or the second upper plate to a lower end of a first or second side beam of a triangular side panel;
- wherein each of the first and second side beams has a hollow, lower end portion and each of the first and second upper plates includes an upstanding anchor rod, said upstanding anchor rods having lower ends attached to said first and second upper plates at 60 degree angles with respect to said first and second upper plates and opposite, upper ends, said opposite, upper ends being dimensioned for insertion into the hollow, lower end portion of a first or second side beam, and means for reversibly locking the upstanding anchor rods within said lower end portions;
- 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 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 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 panel to the shelter and thereby enlarge the shelter;
- and
- wherein, for each triangular side panel,
- the coupling means includes steel strapping having a plurality of spaced-apart apertures;
- said steel strapping is attached to and extends lengthwise along said first and second side beams at a first edge and at a second, opposite edge of each triangular side panel, respectively;
- and
- said steel strapping is oriented with respect to an interior surface of said each triangular side panel either 90 degrees interiorly, 45 degrees proximally, 135 degrees distally, or 30 degrees proximally.
