Abstract:
1. A method of forming a thru-hole to allow wiring or mechanical components to pass through a structure having a first exterior surface, an opposing second exterior surface, a plurality of horizontally oriented, vertically layered internal fluid storage compartments disposed between the first exterior surface and the second exterior surface and a penetration wall defining an internal diameter extending through the structure between the first exterior surface and the second exterior surface to define a penetration, the method comprising the steps of: a) providing an insert ring including a male portion and a separate female portion, the male portion having a male ring and a male flange extending radially outward from the male ring, the female portion having a female ring and a female flange extending radially outward from the female ring, the female ring and male ring being cooperatively engageable to define a cylindrical aperture; b) lining the penetration wall with adhesive; c) locating the female portion proximate the first exterior surface, while inserting the female ring into the penetration; d) locating the male portion proximate the second exterior surface, while inserting the male ring into the penetration; e) engaging the male and female portions within the structure, the male portion and the female portion being brought into compressive engagement with the structure, such that the cylindrical aperture extends through the penetration to define the cylindrical aperture extending though the structure after the male and female portions are brought into compressive engagement, the adhesive being disposed between the insert ring and the structure to couple the insert ring thereto and to create a fluid tight seal between the plurality of internal compartments, and between the plurality of internal compartments and the insert ring; and f) upon completion of step e), passing wiring through the cylindrical aperture.
