This application claims the benefit of U.S. Provisional Application Ser. No. 62/947,349, titled “PLENUM SUPPORT FOR DEMOUNTABLE WALL SYSTEM,” filed Dec. 12, 2019, the entire contents of which are hereby incorporated by reference.
BACKGROUNDDemountable wall systems, and particularly demountable wall systems using glass panels, are used in both residential and commercial settings. Compared to traditional, fixed wall systems, demountable wall systems include panels (e.g., glass panels, metal panels, wood panels, composite panels, polymer panels, concrete panels, fabric-covered acoustic panels, gypsum, etc.) that can be unmounted, relocated, and reinstalled at new locations relatively quickly, and thus provide increased design flexibility. The panels are also often interchangeable such that the wall system can be customized to the particular needs of the setting (e.g., panels can be swapped for panels with different finishing options, different material properties, etc.). Due to their flexibility, demountable wall systems can be used for a variety of different purposes in their setting, including, but not limited to, sound control (acoustical protection), light and solar control, seismic control, safety, air and water resistance, thermal control, clean rooms, emergency egress and ingress, lockability (ability to lock rooms or spaces defined by the wall systems), etc.
Traditionally, demountable wall systems include a frame that is positioned within the area or setting to receive the wall system. The frame includes upper frame components, lower frame components, and/or side frame components depending on the particular shape or needs of the wall system. In some cases, the frame components may define a channel to receive the glass panel. These frame components may be attached using any suitable joining technique, including but not limited to right angles, other angles, mullion, butt joints, etc. The frame component includes a lip at the front of the channel, and to install the glass panel, the glass panel is pushed into the channel of the upper frame component such that the panel can clear the lip, and then the glass panel is lowered into the channel of the lower frame component. As such, the channel of the upper frame component must have a sufficient depth to both accommodate the lifting and lowering action and retaining the glass panel on the frame after installation.
Because the panels are often heavy and the installation requires relatively complex movements in a limited space, installation of the glass panels is not easy, and panels may become damaged if improperly installed. Likewise, uninstalling the panel can be relatively difficult to perform.
With suspended panels, lateral reinforcement may be necessary to provide the panels with structural integrity to withstand the weight of a user leaning against the panel or seismic events that may apply lateral pressure. Suspension of the panels from the ceiling also presents potential issues with regard to access and sound travel. Many traditional buildings include different equipment and machinery within the plenum, which can hinder installation of a panel from above. For clarity, the term “plenum” refers to any spaces between the drop ceiling and the slab of the upper floor (or the main ceiling), regardless of whether the space is designated for air circulation. Therefore, an adaptable solution is required to provide a user with the flexibility to install the panel from a variety of locations. Moreover, when a panel is installed from above, sound can travel over the panel and through the plenum. Existing ceiling tiles typically do not provide sufficient mitigation of this sound travel. As such, there is need for demountable wall systems with plenum support that provide the necessary reinforcement and mitigate sound travel.
Moreover, after installation, a gap may exist between a top of the glass panel and the base of the channel of the upper frame component, which may lead to substandard performance of the wall system (e.g., due to improper sealing, misaligned or angled panels, etc.). Traditional demountable wall systems are often unable to account for any variations in surfaces on which the system is mounted (e.g., warped or slated floors and/or walls, unlevel or non-parallel floors and/or ceilings, etc.). As such, there is a need for demountable wall systems that are easy to install and customize.
SUMMARYAccording to certain embodiments, a method of anchoring a demountable wall system includes introducing a hub into a plenum between a main ceiling and a drop ceiling positioned below the main ceiling, pivoting a telescoping anchor member relative to the hub and to a target angle, extending the telescoping anchor member to an extended length sufficient to span from the hub to the drop ceiling at the target angle, and securing the telescoping anchor member. The telescoping anchor member may be secured at the extended length and the target angle so that the telescoping anchor member is anchored to the main ceiling and coupled for supporting a demountable wall panel on an underside of the drop ceiling.
In some embodiments, the extending of the telescoping member may include sliding one portion of the telescoping anchor member relative to another portion of the telescoping anchor member. The extending of the telescoping anchor member may further include coupling an extension member to the telescoping anchor member.
In some embodiments, the method further includes securing sound-reducing material in the plenum to the telescoping anchor member.
In some embodiments, the method further includes coupling the hub to a frame for receiving the demountable wall panel such that, in an installed state, support is provided for the demountable wall panel through the frame, hub, and telescoping anchor member to the main ceiling.
In some embodiments, the telescoping anchor member includes a first telescoping anchor member. The method may further include pivoting a second telescoping anchor member and a third telescoping member relative to the hub and to either side of the first telescoping anchor member.
According to certain embodiments, a method for reducing sound travel over a demountable wall panel of a demountable wall system includes introducing sound-reducing material into a plenum between a main ceiling and a drop ceiling positioned below the main ceiling, and securing the sound-reducing material to an anchor member. The anchor member may extend within the plenum at a non-vertical angle to the main ceiling from a hub for supporting the demountable wall panel.
According to certain embodiments, a demountable wall system includes an anchoring system for supporting a demountable wall panel. The anchoring system may include a hub and a telescoping anchor member. The hub may be installable in a plenum between a main ceiling and a drop ceiling positioned below the main ceiling. The telescoping anchor member may be pivotally coupled with the hub and extendible to span between the hub and the main ceiling.
In some embodiments, the demountable wall system further includes the demountable wall panel.
In some embodiments, the demountable wall system further includes a frame and a bracket. The frame may define a channel for receiving an upper edge of the demountable wall panel. The bracket may be couplable with or included as part of the frame, positionable to extend through the drop ceiling, and couplable with or included as part of the hub.
In some embodiments, the demountable wall system may further include sound-reducing material coupled with and supported by the telescoping anchor member.
According to certain embodiments, a demountable wall system includes a sound-mitigation system. The sound-mitigation system may include a hub for supporting a demountable wall panel, an anchor, and a sound-reducing material. The hub may be positionable in a plenum between a main ceiling and a drop ceiling positioned below the main ceiling. The anchor member may be installable within the plenum in a position extending to the main ceiling from the hub at a non-vertical angle. The sound-reducing material may be secured to the anchor member.
In some embodiments, the sound-reducing member includes at least one of a ceiling tile, gypsum, foam, a receptacle containing insulation, sound-dampening material, sound-blocking material, or sound-absorbing material.
In some embodiments, the sound-reducing material is sized to span a length spanning between edges of the demountable wall panel. The sound-reducing material may be arranged in or across a path of travel over the demountable wall panel and provide a second barrier to supplement a first barrier provided by a ceiling panel of the drop ceiling.
In some embodiments, anchor member includes a telescoping anchor member pivotally coupled with the hub. The telescoping anchor member may be extendible to span between the hub and the main ceiling.
