Abstract

A method for repairing a multi-sided structure protruding from a first surface. The method comprises mounting a retainer to the first surface, coupling a first brace connector component of a first brace to a first panel, coupling the first panel to a primary retainer connector component of the retainer, coupling a second brace connector component of the first brace to a secondary retainer connector component of the retainer, and introducing a curable material into the space between the first panel and the multi-sided structure, the first panel acting as at least a portion of a framework for containing the curable material until the curable material cures to provide a repair structure cladded, at least in part, by the first panel.

Claims (26)

1. A method for repairing a multi-sided structure protruding from a first surface to cover at least a portion of the multi-sided structure with a repair structure, the method comprising:

mounting a retainer to the first surface;

coupling a first brace connector component of a first brace to a first panel, the first brace extending non-parallel and non-orthogonal to the first panel;

coupling the first panel to a primary retainer connector component of the retainer, the first panel extending generally non-parallel to the first surface such that a tangential plane of the first panel is facing, and spaced apart from, a second surface of the multi-sided structure to provide a space between the first panel and the multi-sided structure;

coupling a second brace connector component of the first brace to a secondary retainer connector component of the retainer, the first brace extending non-parallel and non-orthogonal to the retainer; and

introducing a curable material into the space between the first panel and the multi-sided structure, the first panel acting as at least a portion of a framework for containing the curable material until the curable material cures to provide a repair structure cladded, at least in part, by the first panel;

wherein:

the retainer comprises a base and the primary and secondary retainer connector components each extend in an outward direction, opposite an inward direction, from the base;

the primary retainer connector component is separated from the secondary retainer connector component in a transverse direction by a spacing; and

the base of the retainer comprises one or more mounting features located in the spacing and mounting the retainer to the first surface comprises mounting the retainer to the first surface of using the one or more mounting features.

2. A method according to claim 1 comprising coupling the first brace connector component of the first brace to the first panel before coupling the first panel to the retainer.

3. A method according to claim 1 comprising coupling the first panel to the retainer and concurrently coupling the second brace connector component of the first brace to the retainer.

4. A method according to claim 1 comprising coupling the first panel to the retainer after coupling the second brace connector component of the first brace to the retainer.

5. A method according to claim 1 comprising coupling the first panel to the retainer before coupling the second brace connector component of the first brace to the retainer.

6. A method according to claim 1 wherein coupling the first panel to the retainer comprises forcing the first panel in the inward direction toward the primary retainer connector of the retainer to form a panel-retainer connection.

7. A method according to claim 6 wherein forming the panel-retainer connection comprises extending a protrusion of the primary retainer connector component of the retainer into a receptacle of a first panel connector component of the first panel, the receptacle shaped to prevent removal of the protrusion from the receptacle and the receptacle resiliently deformed by the extension of the protrusion into the receptacle to thereby apply a restorative force to the protrusion to maintain the panel-retainer connection.

8. A method according to claim 6 wherein forming the panel-retainer connection comprises extending a protrusion of a first panel connector component of the first panel into a receptacle of the primary retainer connector component of the retainer, the receptacle shaped to prevent removal of the protrusion from the receptacle and the receptacle resiliently deformed by the extension of the protrusion into the receptacle to thereby apply a restorative force to the protrusion to maintain the panel-retainer connection.

9. A method according to claim 1 wherein coupling the first brace to the retainer comprises forcing the first brace in the inward direction toward the secondary retainer connector of the retainer to form a brace-retainer connection.

10. A method according to claim 9 wherein forming the brace-retainer connection comprises extending a protrusion of the second brace connector component of the first brace into a receptacle of the secondary retainer connector component of the retainer, the receptacle shaped to prevent removal of the protrusion from the receptacle and the receptacle resiliently deformed by the extension of the protrusion into the receptacle to thereby apply a restorative force to the protrusion to maintain the brace-retainer connection.

11. A method according to claim 9 wherein forming the brace-retainer connection comprises extending a protrusion of the secondary retainer connector component of the retainer into a receptacle of the second brace connector component of the first brace, the receptacle shaped to prevent removal of the protrusion from the receptacle and the receptacle resiliently deformed by the extension of the protrusion into the receptacle to thereby apply a restorative force to the protrusion to maintain the brace-retainer connection.

12. A method according to claim 9 wherein forcing the first brace in the inward direction toward the secondary retainer connector of the retainer to form the brace-retainer connection comprises applying force to a shoulder or surface of the second brace connector component with a tool and wherein the second brace connector component comprises one or more sidewalls for aligning the tool with the shoulder or surface.

13. A method according to claim 1 wherein coupling the first brace connector component of the first brace to the first panel comprises sliding the first brace connector in a longitudinal direction relative to a second panel connector component to form a panel-brace connection.

14. A method according to claim 13 wherein forming the panel-brace connection comprises sliding a projection of the second panel connector component into a channel of the first brace connector in the longitudinal direction.

15. A method according to claim 13 wherein forming the panel-brace connection comprises sliding a projection of the first brace connector into a channel of the second panel connector component in the longitudinal direction.

16. A method according to claim 1 wherein the primary and secondary retainer connector components are integral to the base.

17. A method according to claim 1 wherein the one or more mounting features comprises one or more apertures and mounting the retainer to the first surface comprises passing one or more fasteners through the one or more apertures and into the first surface.
