Abstract: The system for mounting elongated panels to a substructure is a steel track having a series of formed connectors for receiving and engaging decking planks. The system for mounting elongated panels to a substructure will allow a deck system to be installed without the use of any mechanical fasteners such as screws, nails or individual fasteners, and will allow installation of deck systems mounted onto wood, concrete, or steel substructures, in a horizontal, vertical, overhead (or anything in between) fashion. The upper fasteners and receivers, referred to as tangs, maintain the desired gap between composite deck boards for the life of the deck.

The integrated unique geometric folding pattern means provides enhanced folding accuracy and correct placement of interactive panels during collapse or assembly of the structure, and also greatly increases the flexibility for multiple unit combinations and component materials selection. The folding transportable structure provides a strong, safe, insulated weatherproof structure with a quick setup time, and requires NO tools or separate loose components for assembly.

Abstract: An anti-icing system may maintain a thin layer of solution on top of pedestrian reception areas to prevent frozen precipitation from remaining frozen on the pedestrian reception areas. This greatly reduces the slippery surfaces that pedestrians would otherwise encounter when using the walk-on surface.

Abstract: A construction for insulating the head-of-wall joint between a wall and a floor or roof thereabove which utilizes an insulating gasket construction positionable between the ceiling track and the building structure thereabove. The insulating gasket member includes two L-shaped sections which includes co-operate to firestop both outwardly facing sides of a head-of-wall joint, but which can also be used singly. Each L-shaped section is attached to an associated side section which extends over the outwardly facing surfaces of a ceiling track with being attached thereto. Each L-shaped insulation gasket section can include securement mechanism such as adhesive on the undersurface of the main upper horizontal portion to facilitate attachment to the top of the track therebelow and can be attached to an adjacent similarly configured L-shaped section by one or more connecting straps extending through slits defined therein.
