Claims10
A metallic device useful for providing structural integrity to a crude metallic opening penetrating a wall of a communications supporting structure, said opening having an axis of penetration therethrough, said device comprising:
- at least one crude opening penetrating wall having dimensions approximate to and less than said crude opening and adapted for insertion along said axis of penetration;
- at least one backing bar disposed perpendicularly to said crude opening penetrating wall and constructed and arranged to be positioned in overlapping and juxtaposed relation to said crude opening;
- wherein said crude opening penetrating wall and said backing bar cooperate with said crude metallic opening to enable formation of a complete joint penetration weld.
A communication antenna supporting structure assembly comprising:
- a communication antenna supporting structure including a crude metallic opening;
- a porthole useful for providing structural integrity to a crude metallic opening, said porthole including at least one crude opening penetrating wall having dimensions approximate to and less than said crude opening and adapted for insertion along said axis of penetration;
- at least one backing bar integrally connected and perpendicularly disposed about said crude opening penetrating wall and constructed and arranged to be positioned in overlapping and juxtaposed relation to said crude opening;
- wherein said porthole and said backing bar cooperate with said crude metallic opening to enable formation of a complete joint penetration weld.
A method of installing a porthole into a crude metallic opening formed within a wall of a supporting structure to provide an access to an interior portion thereof, said crude opening having an axis of penetration, comprising the steps of:
- I) forming said crude metallic opening in said supporting structure by a mechanical cutter;
- ii) providing a porthole having at least one crude metallic opening penetrating wall having dimensions approximate to and less than said crude metallic opening and adapted for insertion along said axis of penetration, said porthole further including at least one backing bar disposed perpendicularly to said opening penetrating wall;
- iii) inserting said porthole into said crude opening wherein said backing bar is positioned in overlapping and juxtaposed relation to said crude opening;
- and
- iv) forming a complete joint penetration weldment between said flange and said supporting structure.
