HIRAM KENNETH LEWIS United States Patent 3,286,420 MEANS FOR ISOLATING PLASTER AND CEILING JUNCTURES Hiram Kenneth Lewis, 3725 E. Campbell, Phoenix, Filed June 17, 1963, Ser. No. 288,126 9 Claims. (Cl. 52241) This invention relates to a means forisolating plaster wall and ceiling junctures and more particularly to a means for isolating plaster wall and ceiling junctures which prevent cracking of the plaster in a building roomwhen the ceiling is suspended from a flexible overhead floor or other structure which deflects vertically and causes relative movement between the plaster of a building room ceiling and the plaster on the walls or wall partitions thereof.
In conventional building structure it has become common practice to construct multiple storybuildings by utilizing steel reinforced concrete slabs to span areas between vertical walls and, thereby, provide superimposed floors beneath which ceiling structures for rooms immediately therebelow are suspended. Thus, the ceiling structures are connected to the bottom portions of these concrete slab floors of the story directly above such ceilings. These suspended ceilings are, thus, vertically movable in accordance with the vertical deflection of the slab floors which support such ceilings. In this structure, cracking has heretofore occurred between the plaster of such suspended ceilings and stationary walls therebelow. Such cracking has been caused by vertical de-, flection of the slab floor structures which permit the ceiling suspended therefrom to move up and down and in such structures where the plaster of the movable ceiling is integral with plaster of upstanding walls and partitions, considerable cracking has occurred in the plaster and has caused substantial damage and maintenance costs for repairing such damage.
Accordingly, it is an object of the present invention to provide a means for isolating plaster walls and ceiling junctures which is very simple and economical of construction and which readily permits slight movement between the paster on a movable ceiling and the plaster on an upstanding stationary wall.
Another object of the invention is to provide a novel channel structure commonly known as a ceiling track which is utilized to interconnect upper ends of studding in a partition wall and which is provided with three channel sections, an intermediate one of which retains studding while the outer ones of which hold lath and plaster for the wall and provides a vertical abutment for plaster of the ceiling so that the plaster of the ceiling is isolated from the wall plaster and is relatively movable adjacent the flanges of the ceiling track or flange structure of the invention.
Another object of the invention is to provide a novel channel structure having three channel portions comprising four channel flanges extending in the same direction to hold studding between the intermediate or middle channel legs and so that lath may be secured at opposite sides of the studding, whereby the outermost channel flanges form an abutment for the wall plaster to not only provide a finish for horizontally disposed portions of a wall structure or partition, but which may also provide a finished structure for vertical edges or ends of partial or full partitions or walls.
Another object of the invention is to provide a novel building structure for supporting studding, lath and plaster in a. unitary structure of a building wall or partition.
Another object of the invention is to provide a novel building structure for properly connecting studding, lath and plaster at both the upper ends and lower ends of walls and partitions to thereby provide a metal finish at the edges of the plaster so that metal baseboards and upper metal outline structure for the plaster is provided to retain it isolated from adjacent building ceiling or wall structures.
Another object of the invention is to provide a novel means for isolating plaster wall and ceiling junctures to prevent cracking between relatively movable wall and/ or ceiling plaster of a building room.
Another object of the invention is to provide a novel one piece channel structure having three separate channel portions for use in studding and plaster wall construction to provide edge finished structure for walls or partitions and for maintaining juxtaposition of the plaster relative to the studding wall and for isolating the edges thereof with respect to adjacent structures.
Another object of the invention is to provide a novel sheet metal channel structure having three separate channels, theintermediate one of which supports studding and the outermost ones of which support lath and plaster; resilient clips engageable with the outermost channel flanges and adapted to support lath adjacent studding in the intermost channel during application of plaster to the lath, thereby, greatly facilitating the assembly of lath and plaster relative to various kinds of wall studding.
Other objects and advantages of the invention-may be apparent from the following specification, appended claims and accompanying drawings in which:
FIG. 1 is a fragmentary vertical sectional view through a building partition or wall structure and suspended ceiling located thereabove; said suspended ceiling being suspended from a deflectible floor structure thereabove;
FIG. 2 is a fragmentary horizontal sectional view of a studding wall structure of the present invention shown with a channel structure of the invention vertically disposed and abutted to a masonry wall or other structure;
FIG. 3 is a cross-sectional view of a channel or wall track structure of the present invention;
FIG. 4 is a fragmentary view of the structure shown in FIG. 3 and taken from the line 4-4 of FIG. 3;
FIG. 5 is a reduced elevational view of a partition illustrating by broken lines, walls and ceiling of a room therearound and showing the channel structure disclosed in FIG. 3 on upper horizontal portions and vertical edge portions of the partition and arranged with relation to the lath and plaster in amanner similar to that shown in FIG. 1;
FIG. 6 is a sectional view taken from the line 66 of FIG. 4, showing by broken lines and arrows the breaking out of the central portion of the structure and the folding back of tabs to provide an opening for a stud and to provide connection members for the channel structure;
FIG. 7 is a cross-sectional view of the base member,
' shown in FIG. 1, but omitting plaster and indicating by broken lines, the insertion of a stud in a downward direction to fit into an opening formed by tabs in the downwardly diverging portions of the base member; and
FIG. 8 is plan sectional view taken from line 8-8 of FIG. 1.
As shown in FIG. 1, a floor surface 10 supports a wall or partition base structure 12 of the invention. This structure 12 is formed of sheet metal and is formed of a single piece of sheet metal comprising horizontal flanges 14 having vertical baseboard wall sections 16 integral therewith and extending vertically in substantially the planes of plaster at opposite sides of the wall. At upper portions 18 of these wall portions 16 the base structure 12 is provided with downwardly converging sheet metal plate portions 20 which are provided with sheared out tabs 22 forming an opening in the downwardly converging portions 20 through which the lower end corner portions 24 of a metal stud member 26 is disposed. The lower end extremity 28 of the stud 26 rests upon the sheared out tabs 22 and these tabs 22 at their ends 30 overlap the portions 14 of the base structure 12.
The stud structure 26 may be of various structural configuration and material, however, the preferred studding structure 26 is a conventional metal stud having an upper end 30 and several of these studs 26 are disposed in vertically arranged position and in parallel relationship to each other, being spaced from each other horizontally along the base structure 12. Upper end portions 30 of these stud structures 26 extend through openings 32 in channel structures generally designated 34. These channel structures 34 are disposed at the upper ends of the studs 30 and the openings 32 in the channel structure 34 are formed by sheared out portions 36 which leave bent up tabs 38 which are extended laterally as shown in FIG. 1 of the drawings. Upper ends of the studs 26 are installed in the openings 32 left by the bent out tabs 38. These openings are in the web portions of the middle channel of the channel member of the invention, as shown in FIGS. 3 and 4, and also in FIG. 1 of the drawings, wherein the tabs 38 are shown bent laterally and secured and supported by the wires 42.
During installation, the normally upper end of each stud 26 is pushed up through the blanked out opening after the tabs 38 have been bent upwardly and laterally, as shown in FIG. 1 of the drawings. Thus, each stud 26 is pushed upwardly through the opening 32, in its respective position, and then the lower end 28 of the stud is moved laterally and downwardly between the inclined portions 20 of the base structure 12. Side end portions 24 of the stud 26, at its lower portion, are located in openings in the inclined portions 20 of the base structure 12, after the tabs 22 have been bent downwardly into the solid line position, as shown in FIG. 1, whereupon the lower end 28 of the stud rests upon these tabs 22 and the lower end of the respective stud is then held against movement longitudinally relative to the base structure, due to the fact that the openings blanked out from the inclined portions 20 hold the studs captive and prevent it from moving in the base structure. It will be understood that when the respective stud 26 is forced downwardly through the openings left by removal of the tabs 22 that the upper end of the respective stud slides downwardly in the aforementioned opening 32 in the channel structure 34 to a position generally, as shown in FIG. 1 of the drawings. The tabs 38 are subsequently secured to conventional furring channels 40 by means of tie wires 42. The furring channels 40 by means of tie wires 44 are secured to runner channel structure 46 which is suspended by tie wires 48 from a conventional concrete slab superimposed flooring 50 or other similar structure which may be subject to vertical movement or deflection as indicated by arrows A in FIG. 1 of the drawings.
In conventional building construction these superimposed floor slabs 50 are steel reinforced slabs and form floors of superimposed stories in buildings. When loaded, these floors 50 deflect, and accordingly, the channels 40 and 46 suspended therefrom, move up and down, carrying ceiling lath 52 and plaster 54 therewith. Thus, the plaster 54 moves vertically in accordance with the deflection of the floor slab 50.
The ceiling plaster 54 at its edge portions 56 adjacent a wall designated B is isolated from the wall B so that movement of the ceiling plaster 54 may take place relative to plaster 58 of the wall or partition B.
Each channel structure 34 as shown in FIG. 3 of the drawings is provided with three channel sections 60, 62 and 64, the channel 34 being formed of a single sheet of metal and having a first pair of flanges 66 defining opposite walls of the channel 62 and also forming walls of the second and third channels 60 and 64 which are provided with additional flanges 68 and 70. Thus, the channel structure of the invention is provided with four flanges extending in the same direction and the first flanges 66 form common dividing walls for the three separate channels.
The flanges 66 are disposed at opposite sides of the studding 26 and support inner sides of conventional plaster lath 69 while the wall plaster 58 disposed on the outer sides 72 of the lath 69 is isolated from the ceiling plaster 54 by the flanges 68 and 70. Thus, these flanges 68 and 70 provide for a sliding or moving connection between the ceiling plaster 54 and the wall plaster 58 on the lath 69. Thus, the lath and plaster is disposed between the flanges 66 and 68 and 66 and 70 and during the placement of the plaster 58, metal strips 74 are wedged between the flanges 68 and 70 and the outer sides 72 of the lath 69 to hold the lath in proper position until after the plaster 58 has been placed on the lath.
Between the adjacent edges 76 of the lath, clips 78 are disposed and projected through openings 80 in the studding 26. A T-head section 82 of these clips 78 overlaps adjacent edges 76 of the lath 69 and, thus, holds adjacent panels of the lath in connection with the studding.
It will be obvious that plaster board or other panelling, such as wood or the like, may be secured and held between the flanges 66 and 68 if desired; thus, taking the place of the lath 69 and plaster 58.
Lower edge portions 84 of the lath 69 rest upon the inclined portions 20 of the base 12 and, thus, these lower edges are urged into close proximity with the studding 26.
The downwardly converging portions 20 of the base 12 are provided with openings which receive plaster during the application thereof to the lath 69, thus, the plaster is anchored to the base 12 and forms acoustical insulation therein.
When the channel structure 34 is used adjacent a masonry wall as indicated at C in FIG. 2 of the drawings, the lath 69 and the plaster 58 is supported by the channel 34 in a similar manner to that shown in FIG. 1. However, the channel 34 shown in FIG. 2 is in a vertical position and adjacent the vertical face 86 of a wall C and, thus, the channel 34 isolates or separates the vertical edge of a wall D from the vertical surface 86 of the wall C.
The flanges 66, 68 and 70, all perform functions similar to that shown in FIG. 1 with regard to the supporting of the lath 69 and the plaster 58 of a wall.
As shown in FIG. 5 of the drawings a wall 88 stands in a building room between respective walls 90 and 92 below a ceiling 94. A horizontal upper portion of the wall 88 is covered by a section of the channel 34 which is as shown in FIG. 3 without the perforations 38 therein. Thus, the channel 34 forms an upper structure for the wall while a vertical section of the channel structure 34 is disposed as shown in FIG. 2 to cover the standing vertical edge of the wall 88.
It will be obvious to those skilled in the art that the flanges 68 and 70 as shown in FIG. 1 of the drawings provide an isolation structure between the ceiling plaster 54 and the wall plaster 58 so that the ceiling may move upwardly and downwardly relative to the wall B without causing relative cracking of the plaster, neither the ceiling or the wall.
It will be obvious to those skilled in the art that various modifications of the present invention may be resorted to in a manner limited only by a just interpretation of the following claims.
