The invention comprises connector for a pair of opposed spaced concrete forming panels. The connector comprises an elongate spacer member having flanges formed thereon intermediate a central portion thereof and each opposite end thereof. A portion of at least one end of the spacer member is sized and shaped to selectively engage an elongate panel bracing member. A composite insulated concrete form and a method of using the insulated concrete form are also disclosed.

In combination, extruded aluminum trim strips joined end-to-end and a splice plate, the trim strips together, the trim strip cross-sections including a web and a pair of opposed angles, the angles and web forming a track for receiving a mid-section of the splice plate with a close sliding fit, the splice plate having lever tabs at opposite ends, notches at sides of the plate, the plate being disposed in the tracks of both lengths of trim strips, the lever tabs and associated edges of the lever tabs formed by the notches being outside of the tracks, the associated edge being arranged in a locking manner with outer surfaces of the angles as a result of the lever tabs being bent in place towards the web.

A hold down clip for retaining one or more ceiling panels on lower flanges of a suspended ceiling tee and allowing removal of the ceiling panels from below after installation. The hold down clip includes at least one outward curved section with a crest between an upper end and a lower end. The clip elastically deforms to produce reactive spring forces when a ceiling panel engages a contact point below the crest of the outward curved section. The clip also includes at least one continuously formed latching section, which may extend from the upper end, lower end, or a transition point below the crest of the outward curved section. The latching section engages the grid tee to generate the spring force. Alternatively, the clip includes a fastener secured to the at least one outward curved section. The fastener is configured for threaded attachment to a receptacle of the grid tee.

A ceiling system including: a ceiling structure suspended in an interior space. The ceiling structure includes: a perimeter frame defining a central opening, the perimeter frame comprising a fabric gripping member; a support grid comprising a plurality of intersecting struts defining a plurality of grid openings, the support grid disposed within the central opening and coupled to the perimeter frame; a plurality of acoustic ceiling panels, each of the acoustic ceiling panels mounted to the support grid and disposed in one of the grid openings; and a tensioned fabric sheet having a perimeter portion that is engaged by the fabric gripping member of the perimeter frame, the tensioned fabric sheet located below the acoustic ceiling panels and covering the central opening.

A ceiling system is disclosed in which two type of ceiling panels are mounted in a support grid. In one embodiment, the ceiling system may comprise: a support grid defining a plurality of grid openings; a plurality of grid-concealment ceiling panels mounted to the support grid and disposed in the grid openings, each of the grid-concealment ceiling panels comprising peripheral edge portions which extend beneath and at least partially conceal the support grid; and one or more tegular ceiling panels mounted to the support grid and disposed within the grid openings, wherein the one or more tegular ceiling panels do not extend beneath the support grid.

Structures used for dividing, supporting, disguising and/or cladding, for example, modular wall panel systems can include frame members that can include or be in the form of a rail having a panel engaging portion with a generally planar mounting surface configured to accept at least one fastener, the panel engaging portion including first and second lateral sides on opposite sides of the generally planar mounting surface. First and second channels can include side walls extending generally parallel to the generally planar mounting surface, the first and second channels facing away from each other.

Disclosed is a suspended ceiling system, a securing member, and process of installing a patterned suspended ceiling system. The suspended ceiling system includes a grid system having first members and second members, and at least one substrate which extends below the grid system. The at least one substrate has an exposed surface and a concealed surface, and the at least one substrate has first sides and second sides which extend between the exposed surface and the concealed surface. Securing members attach to the concealed surface proximate the first sides, and the securing members have grid engagement members which secure the at least one substrate to the grid system. The securing members cooperate with the first members and the second members of the grid system to properly position the substrate and the spacing between adjacent at least one substrates is controlled.

The invention comprises connector for a pair of opposed spaced concrete forming panels. The connector comprises an elongate spacer member having flanges formed thereon intermediate a central portion thereof and each opposite end thereof. A portion of at least one end of the spacer member is sized and shaped to selectively engage an elongate panel bracing member. A composite insulated concrete form and a method of using the insulated concrete form are also disclosed.

A suspended drywall ceiling grid construction comprising a plurality of uniformly spaced parallel sheet metal support bars, a plurality of spaced grid tees carried on lower sides of the support bars, the support bars having regularly spaced centers for engaging and supporting grid tee reinforcing bulbs, the centers and grid tees being constructed and arranged to present lower faces of flanges of the grid tees in a common plane, the support bars having intermediate centers between said regularly spaced centers for receiving butt joint tees, the intermediate centers and butt joint tees being constructed and arranged to present lower faces of flanges of the butt joint tees in a plane a predetermined distance above the common plane.

The present disclosure relates to a set comprising a supporting structure, first and second panels and a fastening device for securing the first and second panels to the supporting structure. The fastening device comprises a top portion, having top and bottom surfaces, first and second edge portions, and first and second legs protruding downwardly from the bottom surface. The first and second panels respectively comprise opposite first and second edge grooves into which the first and second edge portions are configured to be respectively inserted. The first and second legs are flexible and bendable towards each other, and respectively comprise first and second locking elements. An upper surface of the supporting structure comprises an insertion groove comprising a first undercut groove and an opposite second undercut groove. The first and second locking elements are respectively configured to be snapped into the first and second undercut grooves to a locked position.
