A mounting clip and a system for mounting a vertical panel from a support member suspended from a ceiling. The mounting clip has a panel mounting section, a support member receiving portion, and a movable mounting section. The support member receiving portion extends from the panel mounting section. The movable mounting section can be rotated relative to the support member receiving portion to secure the mounting clip to the support member.

A building system includes a building space defined by a structural ceiling and a flooring of a building, and a ceiling system. The ceiling system includes an air permeable suspended ceiling arranged below the structural ceiling, and a plenum space is formed between the suspended ceiling and the structural ceiling and a flooring space is formed between the flooring and the suspended ceiling. A plurality of partition wall sections is arranged in the plenum space extending between the structural ceiling and the suspended ceiling and forms a plurality of plenum modules distributed across the plenum space. Each plenum module includes equipment. The equipment of each plenum module includes a supply air device for delivery of supply air to the associated plenum module for pressurization thereof such that the supply air delivered to the plenum module is supplied to the flooring space through the air permeable suspended ceiling.

A collapsible acoustic honeycomb ceiling installation can be made by cutting desired material into panels. Next, a manufacturer can cut one or more notches into the panels. The manufacturer can assemble the collapsible acoustic honeycomb ceiling installation by aligning the one or more notches on the panels and slideably connecting the panels. The resultant collapsible acoustic honeycomb ceiling installation can provide a versatile decorative feature to a space while maintaining or altering the acoustics of the space as desired. Further, because the ceiling installation is collapsible, a manufacturer or installer can easily transport, install, and removed the ceiling installation.

An arrangement for ventilating a laboratory is provided wherein a plurality of center carrier elements are in a spaced arrangement above a laboratory table row that defines two walking areas, one on each side of the table row. Each center carrier element comprises a vertical column element fastened on an upper end to the laboratory ceiling and at its lower end having center extension arms extending above the of laboratory table row. On the bottom side, the carrier elements carry a first and second air supply conduit in spaced relationship and delimit a lower receiving space therebetween extending over the length of the laboratory table row to carry supply lines. On the top side, the carrier elements carry an exhaust air conduit or alternatively, a side exhaust air conduit is received on side carrier elements opposite the first or the second air supply conduit.

A universal partition clip is formed from a single piece of sheet metal and is adapted to be efficiently mounted to the underside of a T-bar flange. The clip comprises a bottom panel of generally uniform width and a pair of parallel side panels with a pair of generally coplanar lips spaced above the bottom panel. Integral resilient tabs are spaced above the bottom panel and have portions slightly above the lips. The tabs and lips cooperate to mount the clip to the flange portion of the T-bar member.

A interior partition includes a suspended wall track system that includes suspended wall track frame that aligns and receives an interior wall material to create a non-load bearing wall structure. The suspended wall track system may further include a suspended wall track frame that is fitted within a suspended ceiling track hanging from a ceiling floor with an unobstructed interstitial spacing between the suspended ceiling track and the ceiling floor.

A folding wall partition includes foldable panel assemblies. Each panel assembly includes an upper panel and a lower panel. The upper and lower panels extend substantially in a common vertical plane when in a deployed position, and extend laterally outwardly of the common vertical plane in a stacked relationship when in a stored position. A moving mechanism engages the panel assemblies to displace them between the stored and deployed positions. A cover assembly has cover panels. The cover panels extend in a first common horizontal plane when in the deployed position and are substantially coplanar with the ceiling to conceal a cavity. The cover panels extend in a second common horizontal plane higher than the first common horizontal plane and within the cavity when the cover panels are in the stored position.

Components for constructing a ceiling grid across a span free of or with a limited number of suspension wires including main runners with a relatively high moment of inertia secured at their ends with brackets to wall moldings on opposing walls.
