Abstract
A modular anchor has a metal plate having a pattern of holes around a periphery, the forming a boundary of a central inner area, a metal bracket having a raised central portion and parallel wings having upper and lower surfaces in parallel horizontal planes, with the bracket joined to the metal plate at a central location within the hole pattern, the wings and the metal plate coated with a material to facilitate heat welding to membrane; and a transition membrane positioned on the metal plate with the raised portion of the bracket extending upward through an opening in the transition membrane, and with the transition membrane heat welded to the upper surfaces of the wings of the bracket and to the metal plate everywhere within the central inner area, leaving the pattern of holes exposed.
Claims10
A modular anchor for attaching fixtures to a membrane-covered roof, comprising:
- a planar metal plate having a pattern of holes arranged around a periphery of the plate, the pattern of holes forming a boundary of a central inner area of the metal plate;
- a metal bracket having a substantially raised central portion and parallel wings on opposite sides at a lower extremity of the raised central portion, the wings of the bracket having upper and lower surfaces in parallel horizontal planes, with the bracket joined to the metal plate at a central location within the hole pattern by the lower surfaces of the wings being adhered to an upper surface of the metal plate, the upper surfaces of the wings and an upper surface of the metal plate being coated with a material to facilitate heat welding to membrane;
- and
- a transition membrane having an opening of size and shape of the raised central portion of the bracket and outer dimensions substantially greater than the central inner area of the metal plate defined by the pattern of holes in the metal plate, the transition membrane positioned on the metal plate with the raised portion of the bracket extending upward through the opening in the transition membrane, and with the transition membrane heat welded to the upper surfaces of the wings of the bracket and to the metal plate everywhere within the central inner area, leaving the pattern of holes exposed.
A method for attaching a modular anchor to a membrane-covered roof, comprising:
- (a) placing a modular anchor comprising a planar metal plate having a pattern of holes arranged around a periphery of the plate, the pattern of holes forming a boundary of a central inner area of the metal plate, a metal bracket having a substantially raised central portion and parallel wings on opposite sides at a lower extremity of the raised central portion, the wings of the bracket having upper and lower surfaces in parallel horizontal planes, with the bracket joined to the metal plate at a central location within the hole pattern by the lower surfaces of the wings being adhered to an upper surface of the metal plate, the upper surfaces of the wings and an upper surface of the metal plate being coated with a material to facilitate heat welding to membrane, and a transition membrane having an opening of size and shape of the raised central portion of the bracket and outer dimensions substantially greater than the central inner area of the metal plate defined by the pattern of holes in the metal plate, the transition membrane positioned on the metal plate with the raised portion of the bracket extending upward through the opening in the transition membrane, and with the transition membrane heat welded to the upper surfaces of the wings of the bracket and to the metal plate everywhere within the central inner area, leaving the pattern of holes exposed, upon membrane of a membrane-covered roof at a position where an anchor is desired;
- (b) folding the transition membrane back to expose the pattern of holes;
- (c) fastening the metal plate to the membrane covered roof by fasteners through the holes in the pattern of holes in the metal plate, into decking of the roof beneath the membrane of the membrane-covered roof;
- and
- (d) folding back the transition membrane over the pattern of holes and fasteners, and heat welding the transition membrane to the metal plate over the hole pattern and fasteners, and to the membrane of the membrane-covered roof all around the metal plate.
