Abstract

A method of fixing a membrane to a surface is disclosed. The method includes affixing a metallic washer having a heat-activated adhesive layer on a surface; arranging a membrane on top of the surface and the heat-activated adhesive layer of the metallic washer; heating the metallic washer to activate the heat-activated adhesive layer such that the membrane is fixable to the metallic washer; positioning a magnetic clamping heat sink assembly on the membrane; magnetically clamping the magnetic clamping heat sink assembly to the metallic washer causing the magnetic clamping heat sink assembly to apply a force against the membrane when the magnetic clamping heat sink assembly sufficiently overlaps the metallic washer to form a secure bond; and cooling the metallic washer, the heat-activated adhesive layer, and the membrane by removing heat through the magnetic clamping heat sink assembly.

First claim

What is claimed is:

1. A method of fixing a membrane to a surface, the method comprising:
affixing a metallic washer having a heat-activated adhesive layer on a surface;
arranging a membrane on top of the surface and the heat-activated adhesive layer of the metallic washer;
heating the metallic washer via an inductive heating tool to activate the heat-activated adhesive layer such that the membrane is fixable to the metallic washer via the heat-activated adhesive layer bonding to the membrane;
positioning a magnetic clamping heat sink assembly on the membrane adjacent to the metallic washer, the magnetic clamping heat sink assembly including a magnetic assembly including a carrier body defining at least one seat in which at least one magnet is arranged, and a spring resiliently biasing the carrier body;
magnetically clamping the magnetic clamping heat sink assembly to the metallic washer via magnetic attraction between the at least one magnet in the magnetic clamping heat sink assembly and the metallic washer causing the magnetic clamping heat sink assembly to apply a force against the membrane when the magnetic clamping heat sink assembly sufficiently overlaps the metallic washer to form a secure bond; and
cooling the metallic washer, the heat-activated adhesive layer, and the membrane by removing heat through the magnetic clamping heat sink assembly.

2. The method of claim 1 , wherein the heat-activated adhesive layer is applied to an axially raised attachment ring of the metallic washer.

3. The method of claim 1 , wherein the surface is a roof surface.

4. The method of claim 1 , wherein the magnetic clamping heat sink assembly and the metallic washer radially overlap by at least about 75% of an area of the metallic washer when the magnetic clamping heat sink assembly is positioned adjacent to the metallic washer.

5. The method of claim 1 , wherein the magnetic clamping heat sink assembly includes:
a base assembly including a base plate.

6. The method of claim 5 , wherein the spring holds the carrier body at a medial position spaced apart from the base plate when the base assembly of the magnetic clamping heat sink assembly is positioned away from the metallic washer, and
the carrier body is driven downward against a force of the spring to a lower position and into contact with the base plate by magnetic attraction between the at least one magnet and the metallic washer when the magnetic clamping heat sink assembly is positioned on the membrane adjacent to the metallic washer.
