TUBULAR SUPPORT BEAM WITH SELF-DRAINING SURFACE

摘要

A tubular support beam having a self-draining surface, comprising a first channel having a first channel side wall and a first channel bottom wall, wherein the first channel side wall forms a substantially 90° interior angle with the first channel bottom wall and a second channel having a second channel side wall and a second channel bottom wall, wherein the second channel side wall forms a substantially 90° interior angle with the second channel bottom wall. Either the first channel and/or the second channel having an angled or convex top wall, wherein the first channel and the second channel are joined to provide a self-draining surface for the tubular support beam. The self-draining tubular support beam may be implemented into hygienically designed food processing equipment to eliminate undesirable horizontal surfaces.

1. A tubular support beam having a self-draining surface, the tubular support beam comprising:
a first channel having at least a first channel side wall and a first channel bottom wall, wherein a first lengthwise edge of the first channel side wall is contiguous with and forms a substantially 90° interior angle with a first lengthwise edge of the first channel bottom wall; a second channel having at least a second channel side wall and a second channel bottom wall, wherein a first lengthwise edge of the second channel side wall is contiguous with and forms a substantially 90° interior angle with a first lengthwise edge of the second channel bottom wall; at least one of the first channel or the second channel comprising a top wall, wherein a first lengthwise edge of the top wall is contiguous with and forms an interior angle greater than 90° with either a second lengthwise edge of the first channel side wall or a second lengthwise edge of the second channel side wall; a first weld joint joining the first channel and the second channel at a second lengthwise edge of the top wall of the first channel or the second channel, wherein a second lengthwise edge of the first channel bottom wall is aligned with a second lengthwise edge of the second channel bottom wall and separated by a root gap; and a second weld joint formed within the root gap joining the second lengthwise edge of the first channel bottom wall to the second lengthwise edge of the second channel bottom wall to form a tubular support beam having a self-draining surface.
