Heat panel and fastener system
A heat panel system for preventing ice formation about a roof or gutter includes at least two heat panels that are connected using a fastener. The heat panels each include a body including at least one channel configured to accept a heating element. Tongues and grooves or other mating arrangements on the panels and the fastener permit two panels to be joined by a fastener so as to inhibit relative lateral movement and enhance heat transfer between panels. A single panel or a multi-panel system can be mounted directly on the roof, and/or a single panel system can be mounted in a gutter. By using these heat panels and fasteners, heat panel systems of varying widths can be made using the same supplies.
1. A system for the prevention of ice formation on or near a roof of a building the system comprising:
at least two panels adapted for being supported on the building;
wherein each of the panels extend longitudinally of the system;
wherein each of the panels has a first side edge, a second side edge, and a substantially planar bottom surface that extends laterally between the first side edge and the second side edge;
wherein each of the panels has at least one up upwardly-facing, longitudinally-extending channel that is located laterally between the first side edge and the second side edge above the substantially planar bottom surface, that is open at an upper surface thereof, and that is configured to accommodate an electrical heat element; and
a fastener adapted to lock the at least two panels together;
wherein the fastener is formed of a metallic material and is designed to engage both of the first and second panels in abutting relationship along at least a substantial portion of an entire length thereof so as to enhance heat transfer from one panel to another while inhibiting relative transverse movement between the panels.
2. The system of claim 1 wherein the fastener comprises at least two fastener mating components, each, fastener mating component configured to engage a mating component of each of the at least two panels.
3. The system of claim 2 , wherein each panel has plural upwardly-facing channels.
4. The system of claim 1 , wherein each of the panels has a groove one of the side edge thereof that faces a side edge of the other of the two panels; wherein the fastener has two tongues extending outwardly from opposed sides of the fastener; and wherein each of the grooves is configured to engage a respective one of the tongues to prevent lateral movement between the panels and the fastener.
5. The system of claim 1 , wherein each of the panels has a tongue in a side edge thereof that faces the other of the two panels; wherein the fastener has two grooves formed in opposed sides of the fastener; and wherein each of the two grooves are configured to engage a respective one of the tongues.
6. The system of claim 4 , wherein the fastener provides a continuous heat transfer path between the at least two panels along entire lengths thereof.
7. The system of claim 4 , wherein the tongues and the grooves mate to forma dovetail joint extending the length of the panel.
8. A system for the prevention of ice formation on or near a roof of a building the system comprising:
first and second panels adapted to be supported on or near the roof, each panel comprising:
a first side, a second side opposite the first side, a body located between the first side and the second side, and at least one channel located within the body, all of which extend longitudinally of the roof, and
a panel mating arrangement associated with one of the first side and the second side;
a fastener comprising:
a first side and a second side opposite the first side; and
first and second fastener mating arrangements located on the respective first and second sides of the fastener, wherein the first and second fastener mating arrangements engage with the panel mating arrangement of one of the first and second panels; and
at least one heating element inserted into one of the channels to provide heat throughout the first and second panels.
9. The system of claim 8 , wherein each of the at least two panels are of substantially identical construction.
10. The system of claim 9 , wherein:
a first panel and a second panel are secured together by a first fastener; and
the second panel and a third panel are secured together using a second fastener.
11. The system of claim 10 , wherein:
the third panel and a fourth panel are secured together using a third fastener.
12. The system of claim 9 , wherein each panel accommodates multiple laterally-spaced electrical heat elements.
13. The system of claim 12 , wherein the panel mating arrangement of the first panel is a groove in an edge of the first side and the panel mating arrangement of the second panel is a groove in an edge of the second edge, and wherein the first and second fastener mating arrangements are a first tongue extending from the first side and a second tongue extending from the second side.
14. The system of claim 13 , wherein each of the grooves is configured to engage a respective one of the first tongue and second tongue and to prevent lateral movement of the two panels.
