Abstract: A shelter and method of constructing a shelter. The shelter comprises a unitary first shell and a unitary second shell. The first shell is formed by making at least two transverse bends in a single generally rectangular panel and provides a unitary top wall, bottom wall, and first end wall. The second shell is formed by making at least two transverse bends in a single, generally rectangular panel and provides a unitary second end wall, first side wall, and second side wall. The first and second shells are complementarily positioned to create the shelter. A first metallic member is bonded along the peripheral edge of the first shell and a second metallic member is bonded along the peripheral edge of the second shell means. The first and second metallic members adjoiningly facilitate welding the complementarily positioned first and second shells together. A sealable entryway is provided in at least one of the walls.

Abstract: A system for joining two adjacent building structures having opposed openings therein to provide weather and electrical shielding of the juncture and wherein the buildings are not required to be in perfect parallel alignment, including a boot formed into a continuous loop of flexible weather and radio frequency impervious material, the width of the boot being at least equal the maximum spacing between the two buildings at the opposed openings, and attachment members for sealably securing the opposed peripherial edge of the boot to the two adjacent buildings, the boot forming a short length tube communicating one building opening with the other.
