Modular top shield for support column

摘要

A shield is provided on top of a support column that protects liquid or debris from falling onto the support column from the structure above. Additionally, gaskets are provided around the center of the shield to contact components on top of the support column to further provide protection from liquid and debris. The shield is sloped and provides channels to guide liquid or debris and the outer most edge of the shield extends beyond the outer most surface of the support column in the radial direction whether the support column uses a cover or not. The shield may be in a rounded or quadrilateral form and is manufactured in segments to be connected upon installation using a clam shell type design. Mechanical connection schemes including a collar or fastener are provided to secure the shield segments in a connected state.

1. A top cover segment of a modular top cover in which two or more of said top cover segments are connectable for covering the top of a support structure and for shielding the surfaces of the support structure and a surface of a horizontal support structure member from liquid and debris, the top cover segment comprising:
the top cover segment having substantially a semi-circular profile and having a top main surface, an intermediate main surface, an outer edge, and a seam spanning the diameter of the cover segment; a first channel disposed between the top main surface and the intermediate main surface and spanning in a circumferential direction; a second channel spanning in the circumferential direction and at a greater distance from a center portion than the first channel in a radial direction, the center portion is an area of the top main surface near a midpoint of the seam, wherein each of the top main surface, intermediate main surface, and outer edge faces in an upward direction, wherein the seam has a first radial edge and a second radial edge extending in an opposite direction than the second radial edge with respect to the center portion, wherein the center portion is higher, in a vertical direction, than the outer edge, wherein one side of the first channel spans to the first radial edge and a second side of the first channel spans to the second radial edge, and one side of the second channel spans to the first radial edge and a second side of the second channel spans to the second radial edge, wherein an intermediate face extends in a downward direction at an oblique angle with respect to the intermediate surface, the intermediate face faces outward toward the outer edge and spans along the circumference of the intermediate surface, wherein a vertical lip extends in an upward direction at an oblique angle with respect to the outer edge and spans along the circumference of the outer edge, wherein the second channel has the outer edge as a bottom surface and has the vertical lip and the intermediate face as respective side surfaces, wherein the outer edge has a portion extending upward at an oblique angle with respect to a top surface of the outer edge at one of the first radial edge and the second radial edge, wherein a first connection component is disposed along one of the first radial edge and the second radial edge, the first connection component including a recessed portion recessed into the top main surface and a tab extending downward at an oblique angle with respect to the top main surface, and wherein a second connection component is disposed along the other of the first radial edge and the second radial edge, the second component including an extension, in the radial direction beyond the second radial edge, of at least the top main surface, first channel and intermediate main surface, and including a slot along the second radial edge, the slot having a width and a depth corresponding to a width and depth of the tab of the first connection portion.
