Deflection resistant electrical enclosure
First Claim
1. An electrical enclosure for use in poured concrete construction, said electrical enclosure comprising:
- a peripheral wall defining a cavity, said peripheral wall having opposed longitudinally extending walls and opposed laterally extending walls and having a front surface and a rear surface;
at least one physical support located along each opposed longitudinally extending wall to resist deflection of the opposed longitudinally extending walls during pouring of the concrete around said electrical enclosure, said at least one physical support comprising a first fastening mechanism for fastening a first one of the longitudinally extending walls at substantially its midpoint to a concrete form, and, a second fastening mechanism for fastening a second one of the longitudinally extending walls at substantially its midpoint to the concrete form, the first fastening mechanism comprising a first fastener sleeve extending from the rear surface for a distance greater than one half the width of the first longitudinal wall, but less than the width of the first longitudinal wall, and, the second fastening mechanism comprising a second fastener sleeve extending from the rear surface for a distance greater than one half the width of the second longitudinal wall, but less than the width of the second longitudinal wall, said first and second fastener sleeves receiving first and second elongated fasteners, respectively, said first fastener sleeve having a first fastener opening for receiving the first elongated fastener, said first fastener opening being substantially flush with the rear surface, and, the second fastener sleeve comprises a second fastener opening for receiving the second elongated fastener, said second fastener opening being substantially flush with the rear surface, said elongated fasteners are passed through the corresponding fastener sleeves and into the form to resist deflection of the opposed longitudinally extending walls by laterally supporting the first and second longitudinal walls at substantially their midpoint;
a third fastening mechanism comprising a third fastener sleeve located along the peripheral wall, said third fastener sleeve having a third opening substantially flush with the rear surface for receiving a third elongated fastener.

Abstract
An electrical enclosure for use in poured concrete construction having a peripheral wall with opposed longitudinally extending walls longer than opposed laterally extending walls and at least one physical support located substantially midpoint along the opposed longitudinally extended walls to resist deflection of the opposed longitudinal walls caused by the hydraulic pressure of concrete poured around the enclosure. The physical support can be a crossbar extending across the opening of the electrical enclosure with the ends of the crossbar fixed to the longitudinally extending walls. The physical support can also be fastening sleeves extending along at least a portion of the width of the longitudinal walls for receiving elongated fasteners which extend into the concrete form thereby resisting deflection of the opposed longitudinally extending walls.
