Definitions

  • This invention relates generally as indicated to an interior wall system for use in commercial, industrial, institutional and apartment buildings and more particularly to a low-cost, metal movable wall system which can be manufactured through maximum use of mass production techniques and can eliminate the need for extensive engineering expenses heretofore required to determine exact building conditions and manufacturing requirements for more expensive movable wall systems.
  • fixed walls more or less permanent in structure, made of various materials
  • movable partitions The more commonly used fixed walls are made of plaster on gypsum block or lath. These perform well as sound barriers and can be installed at relatively low initial cost. Because they must be built at the job site, however, they delay the completion of new buildings and keep interior space out of use for lengthy periods when remodeling is required. When layout changes are required, fixed walls must be demolished, rubble carted away and new walls built. The resultant dirt and dust can cause malfunction of expensive office machinery and elevators with considerable expense and inconvenience to tenants and loss of rental to owners.
  • Movable metal partitions heretofore employed, which are prefabricated off the job site, permit earlier Occupancy of buildings and earlier return on owners invest ment. Because they are demountable and movable, with completely reusable components, adapting space to changes in layout requirement is much less expensive, time consuming and inconvenient than is possible with fixed walls. High quality movable walls provide sound control equal to that of fixed walls.
  • a further principal object is the provision of a metal movable wall system which makes possible earlier occupancy of a building because of fast delivery of components for assembly at the job site.
  • Another important object is the provision of a panel component for such a reusable wall system consisting of durable, impact resistant steel completely covering a plaster 3,381,438 Patented May 7, 1968 board, gypsum or like core which can easily be cut on site to fit any condition.
  • a further object is the provision of such panel component which is readily adaptable to mass production methods and which has no lateral projections so that it may be stacked one on top of another on pallets for convenient storage and speedy delivery.
  • a still further object is the provision of a metal clad gypsum core panel having the metal faces thereof interfitted in a manner to facilitate the joining of such panels together as well as to the post construction of the present invention.
  • Still another object is the provision of a sturdy post construction which is perforated along its entire length to permit pipe and conduit to pass therethrough at any elevation so that the interior of the wall system may be utilized for a utility space not requiring utilities to be run through the floor or ceiling.
  • Yet another object is the provision of such panel and post construction wherein the panels may snap out and back into place whenever access to the utility space is needed and yet where the panels meet they will butt together snugly in a line single line joint.
  • a yet further object is the provision of an interior partition system, all of the components of which are reusable, and yet which has an extremely handsome appearance with such tight single line joints while still providing maximum access to utilities.

  • FIG. 10 is a fragmentary end elevation of the post construction shown in FIG. 9 as seen from the right thereof;
  • FIG. 11 is an enlarged fragmentary horizontal section taken through such post with the panel components secured thereto;
  • FIG. 12 is a fragmentary horizontal section similar to FIG. 11 illustrating a further form of post construction in accordance with the present invention.
  • FIG. 13 is a fragmentary end elevation of such post construction as seen from the line 13-13 of FIG. 12;
  • FIG. 14 is an enlarged fragmentary horizontal section illustrating a glass panel construction and the post accommodating such glass panels.
  • FIG. 1 there is illustrated in elevation a typical partition system construction in accordance with the present invention.
  • Such partition construction may extend from the semifinished floor F to a finished ceiling C and comprises, reading from left to right, a solid panel 1, a frame post 2, solid panels 3, 4 and 5, a frame post 6, and a solid panel 7.
  • the term solid panel as employed throughout the present description refers not to the interior construction of the panel, which actually comprises two laterally spaced panel members having a substantial opening therebetween, but to the appearance of the panel to distinguish the same from a glass or transparent panel.
  • a plinth or cove 13 extends along the base of the structure and a ceiling runner or frame 14 may extend along the top.
  • each of the panels 1, 3, 4, and 7 comprises laterally spaced panels 16 and 17, the detailed construction of which is illustrated more clearly in FIG. 3.
  • the panels 1 and 7, which extend from the floor to the ceiling, may be as tall as 12 feet and the panels 3, 4 and 5 may be somewhat shorter depending upon the height of the glass transom formed by the panels 9 and thereabove. Since the laterally spaced panels of the solid panel constructions may be substantially identical in form except for variations in height and width, only one such panel will be described in detail.
  • the panel 17, for example may comprise a gypsum or other plaster board type of insulating core 20, having a front metal face sheet 21 adhesively secured thereto as at 22, and extending laterally beyond the edge 23 of the gypsum core and bent as indicated at 24 to form an end flange 25 which extends normal to the planar face 26 of the face panel or sheet 21.
  • the edge flange 25 is bent again at 28 to extend parallel to the face 26 and then flat folded at 29 back upon itself and finally bent at 30 to extend parallel and adjacent the edge flange 25.
  • the sheet 21 thus terminates in a double thickness inwardly directed L-shape flange.
  • the inner or backup sheet of metal 32 is adhesively bonded at 33 to the back face of the gypsum or like material core 20 and extends slightly beyond the edge 23 of the core and is bent at 34 to extend parallel to the end face of the gypsum board and is bent again at 35 to extend parallel and adjacent the back surface of the front face or sheet 21 and is finally bent at 36 to form an end flange 37 terminating at 38 inside the folded portion 29 of the face panel 21.
  • the face and backup metal panels are interlocked together beyond the end or edge 23 of the gypsum core. It will be understood that the opposite vertical edge of the panel, as initially manufactured, will be identical in form to the edge illustrated in FIG. 3.
  • the gypsum board or core 20 may be approximately of an inch in thickness while the front panel 21 may be 24 gauge steel (.0239) while the back panel is 28 gauge steel (.0149).
  • Any adhesive may be utilized for bonding the front and back panel plates to the gypsum core, but it is preferred to employ a rubber contact type of adhesive with good metal adhesion, tack, strength and resilience properties. Although a neoprene type of adhesive is preferred, other types such as reclaimed rubber, butadiene-styrene, butyl polybutylene, buna-N or Thiokol may be used.
  • Such panels which consist of durable, impact resistant steel, completely covering a gypsum core, readily lend to automatic production techniques and reference may be had to the copending application of Marvin D. Merritt, entitled Apparatus and Method for Mannfacture of Building Panels, Ser. No. 330,015, filed Dec. 12, 1963, now Patent No. 3,344,503, for a method of fabricating such panels on a production line basis.
  • the flange 37 may extend parallel to and adjacent the flange 25 with the edge thereof clinched in the flat folded portion.
  • Such panel which constitutes the basic component of the present reusable wall system, having no lateral projections, can be stored on pallets, strapped thereto, and shipped in this manner directly from warehouses to the site of installation for on-site assembly.
  • the panels unique steel and gypsum construction makes it possible to cut panels at the job site, by conventional hand saws, for example, to the exact height and width required. This then eliminates the costly pre-engineen'ng and manufacturing expenses necessary to produce panels to the exact measurement of building interiors.
  • Such panels 16 and 17, which form the solid panels 1, 3, 4, 5 and 7, are thus steel clad gypsum boards wherein the backup sheet interlocks with the face sheet in the manner shown more clearly in FIG. 3.
  • Such panel will not warp and is not easily distorted and is not fragile. In fact, such panel sounds on contact much like a conventional plaster wall.
  • the face sheet 21 may be prime coated and the backup sheet 32 may be flash coated, galvanized, or prime coated.
  • the variation in thickness between the face and backup sheet bonded to the panel contributes to the soundproofness of the panel and a very high degree of sound control in the reusable wall systern.
  • the panels 3, 4 and 5 may be joined in a tight single line joint illustrated at 40 and 41 by means of a special interior post construction indicated generally at 42 in FIG. 2.
  • Such post construction 42 provides rigidity and support throughout the system and the panels 17 snap easily into place and are held thereby rigidly in a continuous grip along the entire preformed edge flange 25 of the face plate from floor to ceiling.
  • Such zipper-type connection of the panel to the post serves to eliminate sound and light leaks, and assures a tight clean joint.
  • Such post construction is illustrated in greater detail in FIGS. 8 through 11.
  • the frame members 2 and 6 may be identical in form to the frame members 8 and 11 and serve to frame glass panel units such as 9 and 10 as well as doors as hereinafter described.
  • Such frames 2, etc. are in a sectional configuration similar to that of an I-beam having a web 45 and flanges 46 and 47.
  • Thickened portions 48 and 49 connect the web with the respective flanges and each flange adjacent the thickened portion is provided with vertically extending ridges 50 and 51.
  • the ridges 50 and 51 projecting inwardly from each flange provide grooves 52 and 53.
  • spreaders 55 and 56 When utilized with the panels 16 and 17, spreaders 55 and 56 may be employed which are of a U-shape construction and the bight portions of which are held to the web 45 by suitable fasteners 57 such as the nut and bolt assemblies illustrated. The bight portions of each of the spreaders are secured in this manner to the Web 45 and extend between the enlarged portions 48 and 49.
  • Each leg of the spreaders is bent inwardly as indicated at 53 and then inclined outwardly at 59 to terminate in inwardly directed flange 60 which resiliently bears against the inner face plate of the associated panel 17.
  • the legs of the spreaders thus serve resiliently to separate the panels 16 and 17 holding the edges of the same against the edges of the flanges 46 and 47 in complete vertically continuous contact.
  • the horizontal rail or frame 8 is identical in form to the vertical frames 2 and 6 and a spreader 62 may be employed secured to the web of the frame 8 by fastener 63 holding the panels 17 and 16 vertically spaced.
  • the frames 2, 6, 8, etc. may be extruded aluminum shapes.

  • the member 65 which fits flush with the top of the flanges 67 and 68, may resiliently be snapped into place with the latch portions 73 and 74 on the legs thereof latching behind the ridges 50. It is noted that the legs will abut the thickened portions 48 and 49 of the frame 8 firmly supporting the member 65 and thus the glass pane 9.
  • the bottom edge 77 of the frame 2 is supported a substantial distance above the floor F by means of fastener 78 passing through vertical slot 79 in stilt member 80 which includes two legs 31 and 82 supported on and fastened by screws 83 to floor runner 84.
  • Such screws 83 pass through upstanding bent portions 85 of the runner on either side of central channel 86 having the rebent sides as indicated with fasteners 87 being provided through the bight portion thereof firmly to secure the runner to the floor F.
  • Such runner includes horizontally extending portions terminating in upwardly bent flanges 88 which include downwardly and inwardly bent ridges 89 cooperating with the central channel to form retaining grooves for seals 90 and the like which may be provided on either or both sides of the central channel.

  • the curved portions 241 and 242 which extend vertically continuously and are parallel are designed to fit the inwardly directed groove 245 in the lateral edges of each of the panel components 16 and 17 which are formed by the interlocked front and back facing plates which clad the gypsum core 20. (See FIG. 3.)
  • the ]-shape or bulb projections of the outer vertical 213 cooperate with the folded edge 29 of the front face plate 21 which restricts the opening of the groove 245 firmly to hold the panel component edge to the post construction.
  • the curved portions 241 and 242 are thus wedged within the groove and the terminal inclined flanges 243 and 24 4 bear against the fold 29 restricting the groove 245 in each of the panel components. Accordingly, as illustrated in FIG.
  • the J-shape portions 24 1 and 24-2 exert a substantial force on the fold edge 2 tending to push the panel 17 on the right to the left and conversely the panel on the left to the right so that the flanges 25 are brought into tight butting relationship with each other and forced securely against the outwardly projecting portion 240 in the center of the outer vertical 213.
  • the panel 139 can readily be installed in the post 42 by inserting the same first in the receptive ceiling channel legs and 186 and aligning the groove 245 in the edge thereof with the formed latching portion 242 and the panel 18) may then simply be driven into tight engagement by moving the same in the direction of the arrow 2190.
  • the panels are thus assembled, only the fine line joint will appear and the entire post construction 42 is completely hidden, and yet provides a st rdy interior support for such panel components.
  • the center of the post is completely open permitting conduit to extend vertically therewithin, but since the space he tween the partition panel components 16 and 17 is also completely open, such post space will not normally be needed for utilities.
  • the center of the post may be filled with an insulating material such as PJF. board further to ensure a sound and fireproof joint between the panel components.
  • insulating material such as PJF. board
  • Such insulation may be placed in the post prior to erection. Holes can be made by push-ing an object through the insulation, cutting or pushing it out. The insulation material improves the sound transmission loss of the partition and slightly minimizes heat transfer.
  • the post cavity may be filled with gypsum mix. Gypsum board may be placed on each side of the post and the panel cavity may be packed with insulation.
  • FIGS. 12 and 13 there is illustrated an alternative form of interior post construction made of only two components 250 and 251 instead of the four components illustrated in the post of FIG. 11.
  • Each component includes respective web portions 252 and 253 which may be provided with vertically spaced enlarged circular apertures 254- for the running of electrical conduit, utilities and the like through the wall.
  • Such members 250 and 251 may be allochirally identical in form and readily interfit and may be secured together to form a rigid and firm box post construction.
  • the member 251 is bent at 255 and 256 to extend generally in the plane of the partition and is bent again at 257 and 25S and folded flat upon itself and then bent at 259 and 260 to extend outwardly at 261 and 262 to form the verticallycontinuous bulb curved I-shape latch portions 263 and 264 which terminate in inwardly inclined flanges 265 and 266.
  • the member 250 is folded at 263 and 269 and then flat folded back upon itself at 270 and 271 and is then again folded at 272 and 273 to extend outwardly of the post to form lateral flanges 274 and 275 which are then folded into the curved bulb I-shape latch portions 276 and 277 which terminate in the inwardly inclined flanges 279 and 280.
  • Each of the members 250 and 251 thus includes a double thickness section extending longitudinally of the panel wherein the member is folded back upon itself and such portions may be provided with outwardly extending identations as indicated at 282.
  • the members 250 and 251 may simply be snapped together into interlatching engagement and, if desired, they may be spot welded firmly to provide a rigid post construction.
  • the vertically continuous J-shape latching portions 276, 263, 277 and 264 will function in the same manner as the similar latching portions provided by the outer vertical member 213 in the post construction 42 illustrated in FIG. 11.
  • the indentations 282 in the members 250 and 251 may serve the same purpose as the shallow channel or indentation 240 in the outer vertical 213 by providing a positive stop for the folded over inwardly directed flange on the outer face 21 of each of the panel components. In this manner, the panel outer faces will be horizontally aligned producing the single fine line joint 40 therebetween. It can now be seen that such interior post constructions afford a rigid firm support for the panel components and yet in no way hinder electrical wiring or utilities passing through the wall.
  • Such post construction cooperating with the unique panel having the interlocked face plates forming the inwardly directed latching channel with the restricted opening permits the panel components quickly and easily to be attached thereto and removed therefrom without damaging the panels.
  • the spring pressure exerted by the continuous latching members of the post draws adjacent panels into a continuous tight butting joint and further draws the panels inwardly against the rigid portion of the post.
  • a special base clip indicated generally at 285 may be provided securely latching the vertical construction to the floor runner 84.
  • Such clip includes a main upstanding U-shaped portion 286 and latch portions 287 and 288 on either side thereof,
  • the center portion 286 fits snugly within such center dovetail channel of the runner.
  • the latching portions 287 and 288 also include hook-shape latches 293 and 294, each of which terminate in inwardly directed tangs 295 and 296 engaging the outer faces of the vertical members 204 and 205, respectively.
  • the spring clips 285 are secured both to the lower end of the vertical and to the floor runner 84 and serve normally to latch the vertical in place.
  • the vertical can then readily be moved or adjusted along the floor and ceiling runners to be placed in the desired position.
  • the panels 189 and 190 may stop short of the floor and may not provide sufiicient backup for the vinyl base or cove 93.
  • This condition may then require a snap-on inner steel base 298 having a bottom inwardly curved configuration 299 terminating in an upwardly extending flange edge 300 which will wedge between the bottom of the runner 34 and the floor F holding it in place with the top edge tight against the wall.
  • the vinyl base or cove 93 may then be positioned flush against the snap-on inner steel base 298 which covers the bottom edge of the panel.
  • the snap-on inner steel base 293 also improves the sound transmission loss of the partition.
  • the posts provided therefor may be reinforced as indicated.
  • Such posts comprise the basic glass or door frame members 303 and 304 which are in the sectional configuration of an I-beam having the relatively thin webs 305 and 306, respectively.
  • Glazing members 307, 308, 309 and 310 each having the central vertically extending glazing channel therein, are snapped into the posts with the legs 311 and 312 of each snapping behind the vertically extending ridges 313 and 314 to secure the glazing member in place.
  • the metallic glazing elements 315 snap within the respective channels having the inwardly folded edges which bear against the faces of the pane 302 centering and maintaining the glass panel properly posi tioned.
  • Each reinforcing member comprises laterally spaced channel portions 320 and 321, the inner legs of which are connected by a bridge 322 forming a central outwardly directed channel surrounding the central glazing channel in each of the glazing members 307 through 310.
  • Vertically spaced screws 324 and 325 passing through the backs of the lateral channels 320 and 321 may be employed to secure the reinforcing members to the central web of the post member.
  • the frame post construction can readily be reinforced to accommodate full height glass panels of considerable thickness and the aluminum shapes used in such glass wall may be shipped to the job in length and fabricated by carpenters in units to receive the glass panes. Accordingly, no pro-engineering or fabrication is required even for the full height glass panel. In this manner, no field measurements or shop drawings are required and the reusable partition system can be erected from architects drawings or from customers sketches.
  • the basic panel component comprises a steel clad gypsum core, the backup sheet of which interlocks with the face sheet to form a restricted opening inwardly directed groove at the vertical edges of the panel which cooperates with the unique inner or concealed post con struction enabling the panels readily to be assembled to such posts forming only a tight single line joint therebetween.
  • Shelving, cabinets, etc. may be attached directly to the wall panel components with toggle bolts and no additional reinforcing is required in the wall unless the loading of such items is abnormal.
  • Pictures may be hung on the panel components, but no drilled holes are required.
  • ordinary metal picture hooks and small wire nails such may be driven into the wall in exactly the same manner as any plastered wall. If the hooks or nails are removed, the holes may be spackled and repainted to look like new.
  • independent steel and gypsum panels held securely in place by the continuous grip of the post, and sealed at ceiling, floor and end walls against leaks, there is provided the kind of privacy and sound control normally afforded only by a gypsum block wall which is plastered on both sides.
  • a post construction for interior partition systems comprising a vertical, and a pair of vertically extending allochiral J-sh-aped latching projections extending laterally from said vertical; panels each comprising an insulating core, front and back face sheets bonded to said core, said sheets extending beyond the edges of said core and cooperating to form vertically extending latching edge channels coextensive with said projections, the adjacent edge channels of said panels being latched to one projection of each pair and thus secured to said post construction.
  • each projection includes a resilient free edge directed toward the other projection of each pair operative firmly to force said panels together into tight butting engagement with each other and into engagement with said vertical.
  • each panel comprises a gypsum board having the front and back face sheets adhesively bonded thereto, said front face sheets being thicker than said back face sheets.
  • said vertical comprises a vertically extending box section with a pair of said vertically extending latching projections extending from opposite sides thereof.
  • channels include overlapped flat folded portions with said shaped edges projecting from said overlapped portions to form said pair of J-shaped latching projections.
  • a post construction for interior partition systems comprising a box section vertical, a pair of allochiral I-shaped latching projections extending laterally from said vertical adapted to snap within vertical latching grooves of panels to be joined thereto, said box section vertical including laterally spaced channels having longitudinally directed edge flanges, lattice means interconnecting said flanges to form said box section vertical, said flanges being lanced vertically intermittently and bent, and means joining the respective bent portions of said flanges to interconnect said channels forming said box section vertical.
  • a post construction for interior partition systems comprising a box section vertical, a pair of allochiral J-shaped latching projections extending laterally from said vertical adapted to snap within vertical latching grooves of panels to be joined thereto, said projections comprising the shaped edges of two channels interconnected to form said box section vertical, said two channels each including laterally spaced flat folded portions forming the lateral walls of said box section vertical, and the corresponding fiat folded portions of each channel lying laterally adjacent each other and being secured together to form latenal walls having four times the thickness of the channel backs.
  • a panel for interior partitions and the like comprising an insulating core, a metal face sheet bonded to one side of said core, a metal back-up sheet bonded to the other side of said core, said face and back-up sheets both extending beyond the lateral edges of said core and being interlocked to form vertical channels at both lateral edges of such panel, each opening away from said face sheet, such vertical channels each being provided with a restricted opening formed by an inwardly directed latching flange on the outer edge of such channels.
