Description

BACKGROUND

Field

Aspects of the present disclosure relate to modular wall systems and methods of installing modular wall systems in hygienic environments. In one aspect, gap cover apparatus are disclosed. In one aspect, backplate arrangements are disclosed. In one aspect, non-progressive installation methods are disclosed. The modular wall systems can eliminate protruding ledges while maintaining structural integrity and hygienic properties.

Description of the Related Art

During installation of wall panels for a wall system, the wall panels may not all align with studs such that the wall panels can be fastened to the studs, which can result in re-forming of the wall panels. The re-forming can cause installation delays and increased installation costs.

Additionally, gaps can occur in the wall system near wall panels, such as between panels, near an edge of the wall system, and/or near a corner of the room. The gaps can not only hinder aesthetics of the room, but can compromise the hygiene of the room. For example, the gaps can be areas in which bacteria grows. The gaps can also be difficult to sanitize. The gaps can also be non-uniform, thereby hindering ease of installation and hindering aesthetics of the room. The gaps can define protrusions that protrude into the room relative other portions of the wall.

Moreover, wall systems can involve progressive installation where a first panel is installed in a corner of an area, and subsequent panels are installed from the location of the first panel. The progressive installation can make installation complicated, expensive, and time-delayed. Additionally, progressive installation can make it difficult to remove individual installed panels from the wall system, rendering maintenance and further work on the wall system difficult and expensive.

Therefore, there is a need for improved modular wall systems and methods of installation thereof that facilitate panel alignment, covering gaps, and non-progressive installation to reduce installation time, installation costs, and installation complexity while maintaining enhanced aesthetics and hygiene of the hygienic environment.

The backplate 223 includes one or more first fastener openings 304 configured to fasten to one or more first studs (two are shown in FIG. 3) of the studs 213.

FIG. 4 is a schematic back view of the modular wall units 114, 115 shown in FIG. 3, according to one implementation. The respective outer panel 166 of each modular wall unit 114, 115 includes five walls (a front wall and four side walls) disposed about the front face 167 of the respective non-metallic inner panel 165. During a method of forming the modular wall units 114, 115, the outer panel 166 is a flat sheet of metal having the thickness T3, and flat sheet of metal is bent into the shape of a rectangular prism that has the front wall and the four side walls. The non-metallic inner panel 165 is adhered, using a second adhesive, to an inner surface 181 of a back face 180 of the respective outer panel 166. The second adhesive includes one or more hydrofluoroolefins, such as trans-1,3,3,3-Tetrafluoroprop-1-ene (HFO-1234ze), and the second adhesive is water based. The second adhesive is pressure sensitive. In one example, which can be combined with other examples, the second adhesive is applied with a spray-gun and the second adhesive dries and tacks in less than 1 minute, such as about 20 seconds. Each of the modular wall units 114, 115 includes one or more first flanges 401 (two are shown) extending relative to a first side 402 of the outer panel and having the plurality of first fastener openings 302 formed in the one or more first flanges 401. The modular wall units 114, 115 each include one or more second flanges 404 (three are shown) extending relative to a second side 405 of the respective outer panel 166 and having the plurality of second fastener openings 303 formed in the one or more second flanges 404. For each modular wall unit 114, 115 the second side 405 opposes the first side 403.

The one or more first flanges 401 include a plurality of first flanges 401 spaced from each other along a first pattern having first gaps 406. The first gaps 406 are disposed between the first flanges 401 and outside of the first flanges 401. The one or more second flanges 404 include a plurality of second flanges 404 spaced from each other along a second pattern having second gaps 408. The second gaps 408 are disposed between the second flanges 404 and outside of the second flanges 404. The plurality of first flanges 401 are aligned with the second gaps 408 and the plurality of second flanges 404 are aligned with the first gaps 406.

The first pattern (of the first flanges 401 and the first gaps 406) is configured to interleave with the second pattern (of the second flanges 404 and the second gaps 408) in an alternating arrangement. In FIG. 4, the first pattern of the modular wall unit 115 is shown as interleaved with the second pattern of the modular wall unit 114 in the alternating arrangement. Each of the modular wall units 111-125 shown in FIG. 1 is arranged and fastened to a plurality of backplates for the respective wall 101-103 with first and second flanges 401, 404 in the alternating arrangement described for the modular wall units 114, 115 shown in FIG. 4. The interleaving and alternating arrangement is used for the modular wall units 111-125 such that each modular wall unit 111-125 is independently detachable from the respective plurality of backplates by removing the first fasteners 301 and second fasteners from the first fastener openings 302 and the second fastener openings 303 of the respective modular wall unit 111-125. For example, the modular wall unit 115 can be independently detached from the backplates 221-226, the one or more base frames 208, and/or the gap cover apparatus 171 of the second wall 102 without first removing any of the other modular wall units 114 or 116-121 of the second wall 102. The independent detachment of individual modular wall units 111-125 from the backplates 221-226 of the modular wall system 100 facilitates ease of replacement of modular wall units 111-125, and ease of maintenance for the modular wall system 100. As an example, one of the modular wall units 111-125 can be independently replaced in a time that is less than 1 hour, such as 30 minutes. The independent detachment of individual modular wall units 111-125 also facilitates ease of conducting further installation of equipment. As an example, a modular wall unit 111-125 can be replaced with a modular wall unit that has a differing opening to receive equipment therein.

The interleaving and alternating arrangement also facilitates a non-progressive installation of the modular wall units 111-125 as the walls 101-103. For example, the first modular wall unit need not necessarily be installed at a corner of the operating room 160. For example, the first modular wall unit installed for the second wall 102 could be the modular wall unit 115 or the modular wall unit 117 such that the modular wall unit 115 or the modular wall unit 117 is fastened to one or more of the backplates 221-226 before the other modular wall units of the second wall 102. Each of the modular wall units 115, 117 is fastened and installed at a distance from each corner 197, 198 (shown in FIG. 1) of the second wall 102. Non-progressive installation simplifies the installation and saves time and money compared to operations that use progressive installation. The interleaving and alternating arrangement of the first and second flanges 401, 404 can be used for the gap cover apparatus 131-134 to facilitate the non-progressive installation and independent detachment thereof.

Each of the first and second flanges 401, 404 includes a width W6. The width W6 can be 6 mm or more, for example. In one embodiment, which can be combined with other embodiments, adjacent flanges 401, 404 are spaced from each other by a spacing S9 in the interleaving and alternating arrangement. The spacing S9 can be 10 mm, for example. In one embodiment, which can be combined with other embodiments, each of the first and second fastener openings 302, 303 is a longitudinal slot having two semi-circular end sections and a rectangular middle section.
