Self-Sealing Mounting Bracket for Roof Mounted Structures

摘要

A self-sealing mounting bracket includes an outer shell that defines at least one downwardly facing chamber. A plunger is located in the downwardly facing chamber and is slidable within the chamber. The chamber is filled with sealant either at the manufacturing facility or in the field. Larger openings are formed in the top of the outer shell that align with and provide access to bolt holes in the top of the plunger. Smaller openings in the top of the outer shell are for attaching the shell to a roof with lag bolts. The mounting bracket is located on a shingled roof and lag bolts are inserted through the larger openings and threaded into the roof deck. The heads of these lag bolts pass through the larger openings and engage the plungers to press the plungers down in their chambers. This, in turn, compresses, squeezes, and extrudes sealant between the mounting bracket and the roof below forming a water tight seal. The outer shell is then firmly attached to the roof with additional lag bolts inserted through the smaller openings and their aligned bolt holes and threaded into the roof deck. Mounting hardware for items such as solar panels can then be secured to the bracket.

主权项

1. A self-sealing mounting bracket for use in securing items to a roof, the self-sealing mounting bracket comprising:
an outer shell having a top wall and defining at least one downwardly open chamber; structures on the outer shell by which auxiliary hardware may be selectively secured to the mounting bracket; a plunger having an upper surface and being slidably disposed in the at least one downwardly open chamber, the plunger being movable between a first position adjacent the top wall of the downwardly open chamber and a second position displaced downwardly from the first position; a first mechanism for selectively moving the plunger from its first position toward its second position when the self-sealing mounting bracket is being secured to a roof; and a second mechanism for securing the outer shell to the roof sealant within the at least one chamber being compressed against the roof when the plunger is selectively slid toward its second position to form a seal between the self-sealing mounting bracket and the roof.
