BUILDING PANEL WITH A MECHANICAL LOCKING SYSTEM

VALINGE INNOVATION AB, V...

1. A set of panels is provided with a mechanical locking system comprising a displaceable tongue, which displaceable tongue is arranged in a displacement groove at a first edge of a first of the panels, the displaceable tongue is configured to cooperate with a first tongue groove at a second edge of an adjacent second of the panels, for locking of the first edge and the second edge in a vertical direction,wherein the displaceable tongue is of a longitudinal shape and resilient, a spring constant of the displaceable tongue varies in the longitudinal direction of the displaceable tongue, and a middle section in the longitudinal direction of the displaceable tongue has a higher spring constant than a first edge section of the displaceable tongue, and
wherein the mechanical locking system is configured such that, during assembly of the first of the panels and the adjacent second of the panels, the first edge section of the displaceable tongue cooperates with a guiding surface of the second edge of the adjacent second of the panels before other sections of the displaceable tongue cooperate with the guiding surface,
wherein an inner long edge of the displaceable tongue comprises protrusions arranged in the displacement groove, wherein the protrusions are adjacent to one another along the longitudinal direction of the displaceable tongue having the longitudinal shape, the protrusions are spaced along the longitudinal direction of the tongue, and the protrusions are bendable.

STRUCTURAL WALL PANEL SYSTEM

1. A composite panel wall system for spanning from floor to floor in a building structure, comprising:a plurality of structural framing members, each having a longitudinal axis;
a plurality of insulated wall panels, each having a periphery edge and a longitudinal axis, each of said wall panels being affixed to at least one of said framing members wherein the longitudinal axis of each wall panel is aligned with the longitudinal axis of each framing member;
a first edge extrusion having a protruding male extension extending therefrom with a sealing gasket affixed thereto, said first extrusion received about at least a portion of said periphery edge;
a second edge extrusion having a channel seal element received about a remaining portion of said periphery edge;
a jamb tab affixed to a rear surface of each of said panels;
a clip on a threaded vertical connector affixed to said jamb tab; and
a channel configured to be affixed to a building structure,
wherein said sliding clip engages with said channel to support said panel on said building structure in a vertically adjustable fashion, and
wherein said first edge extrusion on a first of said plurality of panels interfits with said second edge extrusion on a second of said plurality of panels positioned adjacent said first panel such that a space left between said adjacent first and second panels allows expansion and contraction wherein said male extension moves within said channel to maintain a seal despite said expansion and contraction.

VENT ASSISTED SINGLE PLY ROOF SYSTEM

VADA, LLC, Olney, IL (US...

1. A ballast free method for improving fleece backed single ply roof performance in wind conditions on a roof having a substantially flat deck with an existing built up roof surface, said deck having turbulent wind vortex areas and a field-of-roof area outside the turbulent wind vortex areas, said turbulent wind vortex areas having a higher wind load than the field-of roof area, comprising:determining the turbulent wind vortex areas of the substantially flat deck,
gluing and mechanically fastening one or more strips of a single ply fleece backed membrane to said existing built up roof surface in the turbulent wind vortex areas, each single ply membrane strip having a row of fasteners along a first side at a roof edge, a parapet or bordering another strip and a row of mechanical fasteners along a second side;
loose laying and seaming together single ply fleece backed membrane sheets over the entirely of the existing built up roof surface in the field-of-roof area, said strips of single ply roofing membrane in the turbulent wind vortex areas having a row of mechanical fasteners on a transition between the turbulent wind vortex areas and the single ply membrane sheets in the field-of-roof area; and,
installing at least one vent only in the field-of-roof area outside of the turbulent wind vortex areas.
