Dome cover supporter

摘要

A dome cover supporter is capable of improving durability of a product and extending a life span thereof by preventing roof panels from protruding upwardly by supporting a dome cover used in a storage tank, achieving resistance against a load by decreasing surface roughness, and extending a life span by preventing gaskets from being exposed to ultraviolet rays. The dome cover supporter includes a supporter including supporter main body formed in a vertical direction, a base formed in lower portion of the supporter main body to support the supporter main body against the ground, and horizontal extending pieces bent in an upper portion of the supporter main body to be extended; and a fixing member fastened to an upper portion of the supporter to maintain a seal by fixing and pressing roof panels.

主权项

1. A dome cover supporter with an “I” shape cross section, comprising:
a bottom flange having a first length and a first width with a first midpoint; a top flange having a second length and second width with a second midpoint such that the second length and the second width are substantially equal to the first length and first width of the bottom flange, wherein the top flange is partitioned at the second midpoint into a first dome panel support extending from the second midpoint in a direction parallel to the bottom flange and a second dome panel support extending from the second midpoint in a direction opposite to the first dome panel support and parallel to the bottom flange, the top flange including a pressing plate conduit centered at the second mid-point, and having two sidewalls and a bottom surface formed from a respective portion of each of the first dome panel support and the second dome panel support nearest the second midpoint; a web affixed at one end to the first midpoint and extends away from the bottom flange in a perpendicular direction, and at an opposite end has an expanded portion that is affixed to the second midpoint and perpendicular to the top flange, wherein the expanded web portion extends through the bottom surface of and into the pressing plate conduit; a bolt conduit having a threaded inner surface formed in the expanded portion of the web, wherein the bolt conduit is positioned at the second midpoint and extends into the pressing plate conduit from the expanded portion of the web, such that side surfaces and the threaded inner surface of the bolt conduit protrude into the expanded portion of the web and the pressing plate conduit; and a pressing plate having a fourth length substantially equal to the first length, two side surfaces, a bottom surface, and a top surface with a fourth width with a fourth midpoint substantially equal to a width of the pressing plate conduit, at least one bolt hole positioned at the fourth midpoint and aligned with the bolt hole conduit, such that when the pressing plate is affixed onto the pressing plate conduit by inserting a bolt through the bolt hole into the bolt conduit, the top surface of the pressing plate is substantially coplanar with the first and second dome panel supports of the top flange, and the bottom surface of the pressing plate opposes the bottom surface of the pressing plate conduit and surrounds a top surface and the protruding side surfaces of the bolt conduit.
