10 Claims. (Cl. 72-116) This invention relates to building constructions, and has reference more particularly to arch constructions adapted for rooms where plastic paint or wallpaper is used as a decorative finishing material. One of the common forms of construction used for building is to provide partitions and walls having wallboards of gypsum or the like, covered with a plastic paint. In forming arches for doorways, windows, etc., it is a rather difficult task to so shape the wallboard that the desired shape of arch is obtained.
'An object of this invention, therefore, is to provide an arch construction for use with wallboard, which is adapted for receiving plastic paint or wallpaper as a decorative covering.
Another object of this invention is to provide an archfor building construction which can be easily'erected with a minimum amount of labor and expense to produce arches whichare of pleasing contour; also to improve arch constructions in other respects hereinafter specified and claimed.
Reference is to be had to the accompanying drawing forming a part of this specification, in which:
Fig. 1 is a perspective view of my improved arch construction with parts broken away to disclose the construction,
Fig. 2 is a'perspective view of a metallic member used in the arch construction,
Fig. 3 is a sectional plan view taken on line 33 of Fig. 1, v
Fig. 4 isa sectional elevation through a modified form of arch construction, and
Fig. 5 is a sectional elevation through a still further modified form of arch construction.
In constructing the framework of a building adjacent a'doorway, a pair of spaced vertical studs I II are connected by a horizontal frame member I I. In order to form an arched opening, I construct my improved arch of U-shaped metal strips I2 and I3, the strip I2 having a web I4 and outstanding flanges I5, while the strip I3 has a web I6 and outstanding flanges I'I somewhat greater in width than the flanges I5 for purposes to be hereinafter described. The webs I4 and I6 are placed in abutting face to face relation with the flanges I5 and I1 all extending in the same direction. (Fig. 2.) web I6 is narrower than the web I4 by an amount equal to twice the thickness of wallboard. I8 or other suitable board-like sheets of building mamade using the metal arch unit as a guide.
It will be noted that the of the resulting unit for the purpose of receiving the edges of the wallboard I8.
The arch units are preferably made in pairs which are arranged to meet at their upper ends at a point 2 I, below the frame member I I. Nails 22 are driven through the upper ends of the flanges I'I into the frame member II and flanges I! are preferably sufficiently wider than flanges I5 to allow clearance in nailing. The lower ends of the arch units lie in abutting relation against the studs I0 and are secured thereto by nails 23 driven through the lower ends of flanges II into said studs. Board receiving metal units 24 are I secured to the studs III by nails 25 and said units 24 reach from the lower ends of the arch units to the floor 26 of the building to form side facings for the wall opening. The units 24 are con-' structed similarly to the arch units previously described, except that they are straight rather than arch shaped.
In erecting the wallboards I8, a full board is laid across the arched opening and a mark is The board is then sawed out along the mark and the resulting wallboard I8 with itslower edge the shape of the arch unit is slipped into the arch channel I9 and is nailed in place by nails 28 to the studs I0 and frame members II. Similar wallboards 29 are nailed to the studs III in a plane with boards I8 to form'a wall, and the edges of boards 29 below the arch units are inserted in the edge channels of members 24. A perforated metal tape 30 is then preferably applied over the joints of the wallboard-s by means of a joint filler cement. The wall can then be decorated with a plastic paint 3I which may extend not only over the wallboards I8 and 29, but also over the arched web I4 and the board receiving side facing sections 24. Wallpaper may also be used instead of plastic paint in which case it may be desirable to provide a depressed edge in the wallboard panels so that flanges I5 of the arch units and facing members will lie flush with the wallboard surface. Joint cement may also be used to blend the edge of flange I5 with the wallboard surface by a feathered joint.
In the form of construction shown in Fig. 4, an arched unit 32 is constructed very similar to that hereinabove described, except that this arched unit is adapted for receiving plasterboards 33 of gypsum, fiber board, etc. In order to form a ground for a layer of plaster 34 to be applied on the exterior face of the plasterboard 33, I form the arch fianges, corresponding to flanges I5 in the above described structure, into a bead 55 35, which has a dimension equal to the thickness of the layer of plaster 34 to be applied. After the plaster layer 34 is applied, any desired decorative material, such at flat wall paint, plastic paint or wallpaper may be applied over the plaster layer and over the exposed face of the arch unit 32.
In the form of construction shown in Fig. 5, I illustrate a construction which may be varied in width to accommodate studs ill of different widths. In this type of construction, an archshaped metal strip 31 is provided with a transversally extending flange 38 along one edge thereof, said flange 38 terminating in a reverse bent flange 39 of greater width than the flange 38. Lugs 40 are struck outwardly at intervals along the strip 31 and cooperate with the flanges 39 to form an arched channel 4| for reception of the cut edge of the wallboard I8. Prongs 42 are also struck out at intervals from the strip 31 and engage a strip of expanded metal 43 which maybe cut to a width substantially equal to the thickness of the wall through which the arched opening passes. The prongs 42 are arranged to extend through the openings in expanded metal 43 and are then bent back substantially parallel with the strip 31 so as to firmly engage the strip of expanded metal 43. The lugs 40 are nailed to the framework of the building in a manner similar to that heretofore described for the form of the device shown in Figs. 1, 2, and 3 in which flanges H are nailed to the studs. A layer of plaster 45 is applied to the strip of expanded metal 43 using the outer edges 46 of the flanges 38 and 39 as a plastering ground. A layer of plastic paint 4'! may then be applied over the entire structure in sufficient thickness to conceal the junctions of the flange 39 with the wallboard l8 or the edges of flanges 39 may be blended with the wallboard surface in a manner hereinbefore described so as to permit applying a fiat paint or wallpaper.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:--
1. In an arch construction, a pair of arched U-shaped metal strips of different' widths and having webs and edge flanges, said strips having their webs secured together in face abutting relation, said edge flanges cooperating together to form edge channels, and substantially rigid sheets of material having arched edge sections received in said channels to form a unitary arch construction.
2. In a building construction, the combination with the framework of a doorway or other opening, of an arch composed of spaced channel members, connected by an arched, elongated metal sheet, said channel members extending outwardly from said sheet, at the margins thereof and substantially rigid sheet material received in said channels and secured to said framework.
3. In a building construction, the combination with the framework of a doorway or other opening, a channel-shaped, arched member having edge flanges secured to said framework, a second channel-shaped arched member greater in width than the flrst mentioned arched member and secured thereto in web abutting relation to form an arch unit with edge channels, and a substantially rigid wing sheet received in said edge channels and secured to said framework.
