Abstract
An insulated building for enclosing a refrigerated space is assembled from a plurality of standard-sized modules with each module connected to its adjacent module through a joint interface that includes confronting sealing surfaces that are formed parallel to, perpendicular to, and obliquely to the plane of the modules and connected together by a threaded fastener that extends at an oblique angle to the plane of the modules so that each pair of confronting surfaces are placed under a positive sealing force to provide both a moisture-proof and structurally rigid joint.
Claims6
A modular, air-tight insulated structure for enclosing a refrigerated area fabricated from a plurality of roof, floor, and wall modules, each of said wall modules comprising:
- a structurally rigid frame means that includes spaced apart top and bottom members connected to spaced apart side members;
- a first planar sheathing material on one side of said frame and a second planar sheathing material on the opposite side of said frame to define an enclosed interior space;
- insulating media located within the interior space defined by said sheathing material and said frame;
- each of said wall modules connected to its adjacent wall module through a joint interface that includes:
- a first sealing surface joining the exterior side of said module and aligned substantially perpendicular to the plane of said module;
- a second sealing surface joining said first sealing surface and aligned substantially parallel to the plane of said module;
- a third sealing surface joining said second sealing surface and aligned at an oblique angle relative to the plane of said module;
- a fourth sealing surface joining said third sealing surface and aligned substantially perpendicular to the plane of said module and substantially parallel to said first sealing surface;
- said first and second planar sheathing material each including marginal edge portions that are bent out of the plane of the module with said edge portions substantially perpendicular to the plane of the module, the edge portions of said first sheaths overlying said first sealing surfaces and the edge portions of said second sheaths overlying said fourth sealing surfaces;
- and
- fastener means extending along an axis substantially normal to said third sealing surface to apply a direct sealing compression force to said third sealing surfaces to effect direct surface-to-surface contact therebetween, a portion of said direct sealing compression force resolved into sealing forces on the remaining parts of said first, second, and fourth sealing surfaces, the sealing forces on said first and fourth sealing surfaces placing said edges of said first and second sheaths under compression therebetween.
