3 Claims. (1. 2074) The present invention relates to separating strips to be placed between adjacent edges of panels forming a wall whether such edges extend vertically or horizontally.

The principal object of the present invention is to prow'de separating strips which will seal the joints between wall panels of plywood to prevent moisture from running or even from infiltering into the joints between adjacent panels whether such joints extend vertically or horizontally. 1

In thus sealing wall joints it is an object to provide such separating strips which will fit the panel edges even though the thickness of adjacent panel edges may be somewhat diflerent or such edges vary somewhat in thickness, or are otherwise irregular. Moreover, such strips will not prevent expansion or contraction of the panel edges at the joint caused by atmospheric changes in temperature or humidity, or both.

It is also an object to provide such separating strips which can be retained in a panel joint by the panels and without requiring separate mounting.

Another object is to provide such separating strips which can be fitted to a wall joint and installed quickly and easily during the installation of the wall, and which do not require any special preparation of the panel edge or wall to accommodate such separating strips.

Although economical to produce, such separating strips are very durable and not easily damaged either before, during or after installation in a wall joint.

A further object is to provide such separating strips which will be attractive in appearance but when colored to match the wall will be unobtrusive. such strips can be of a color contrasting with the color of the wall to produce a decorative effect.

Separating strips for accomplishing the foregoing objects should be adapted for installation in substantially the same manner both in vertical joints and in horizontal joints of a wall. Such strips are made of extruded pliable sluggishly elastic plastic material of modified H- beam cross section, Each strip has a web engageable between the edges of adjacent panels and a wide flange on one edge of such web having portions extendingequal distances oppositely from the web. Such wide flange is fitted behind the adjacent panel edges. At the exposed side of the wall the vertical strips have crested flanges, the edge portions of which engage and are flattened against the adjacent edge portions of the anels forming the joint. At the exposed side of the wall the horizontal strip has a downwardly extending flange engageable with the lower panel face and a drip projecting outwardly and downwardly from the web of the strip and the root of the downwardly projecting flange.

FIGURE 1 is an elevation of the exposed face of a wall section including strips of the present invention.

FIGURE 2 is an enlarged bottom perspective of a portion of such a wall showing a stretch of horizontal joint and a stretch of vertical joint.

FIGURE 3 is a horizontal section through a vertical joint taken on line 33 of FIGURE 2 and FIGURE 4 is a vertical section through a horizontal joint taken on line 4-4 of FIGURE 2.

FIGURE 5 is a transverse section through a separating strip for an upright joint in relaxed condition.

FIGURE 6 is an elevation of an exposed wall section face showing an arrangement of joints and strips dilferent Alternatively,

areas Patented Dec. 29, 1964 from that of FIGURE 1, and FIGURE 7 is an enlarged bottom perspective of such a wall showing horizontal and vertical joint portions.

The separating strips of the present invention can be made of different size depending upon the thickness of the'wall panels. Such separating strips are particularly useful for sealing the joints between plywood panels used as a wall facing. Such plywood panels may, for example, be one-half inch, five-eighths inch or three-quarters of an inch in thickness to be used without exterior covering as a surface providing adequate structural strength to Withstand wind and weather loads and wall rigidity when properly secured to the wall framing. Preferably the plywood sheets are of exterior grade becausethey are water-proof.

When plywood is used for the exterior wall surface the panels 1 are formed of rather large sheets of plywood, a conventional size being 4 feet by 8 feet. Such sheets can be applied so that the length of each sheet extends vertically, as shown in both FIGURE 1 and FIGURE 6 of the drawings, or horizontally, depending upon the shape and size of the particular wall. In either case the framing structure on which the surface sheets are mounted is in the form of a grid so that the edges of each plywood sheet will be backed by frame members 2 spanning both the vertical joints 3 and the horizontal joints 4. The edge portions of the plywood. sheets I are then nailed to the framing members 2 at sufficiently close intervals so that each panel will be secured adequately about its edge. The panel will be inherently sufiiciently stiif so that the central portion of the panel will not be easily bendableappreciably when the panel edges are thus backed.

Where plywood sheets are secured to such a framing structure they can be applied most readily by simply butt joining their edges so that the outer faces of adjacent panels are flush. Since there is no overlap of the panel edges at the joints, the problem is presented ofmaking such joints water-tight. One customary procedure has been to calk such joints with some type of calking material. If this material is in the form of a paste it isdiflicult to apply it so that it will penetrate into the joints and such paste material is inclined to dry out and become brittle or to be forcedout by working of the panel edges as they swell or shrink, caused by temperature or humidity changes. Alternatively, the joints between the panels can be calked with fibrous calking material, such as calking cotton. Use of either type of calking material requires considerable labor. Alternatively, the joints can be covered with wood or metal battens, but it is then necessary to seal the joints between the battens and the panels, in many cases. Moreover, the application of such battens also involves considerable work and the completed structure is considered to be unsightly by many people.

The strips of the present invention provide weathertight joints between the panels 1, both vertically and horizontally. Such strips are of modified H-beam cross section including a web portion 5 which serves as a separat ing strip between the adjacent edges of adjacent panels. Wide flanges 6 integral with one edge of the web 5 extend in opposite directions from such web to form a planar flange to be located at the inner side of the wall facing. These flanges can be interposed between the edge portions of the sheets 1 and the framing members 2.

When the plywood sheets are nailed to the framing memi i ni t e. edg -'por i s o th pane si ei ed be rtw e rthe .oppbsite vflanges, the i e p r ons flang I? willrbefla en d ag he ou rs rfa f.- p els asshqwn FIGURES r'l.

Such disposition of the strips at a joint will prevent water from running ofi a drip into the cavities of the vertical strip behind the flange portions 7 which are located below a horizontal strip. Where a horizontal joint intersects a vertical joint as in FIGURES 7 and 8 the e nd's of tlie horizontal strip flanges 9 simply butt against the edges of the "upright strip flange 7.

The wall 'ioiht sealing strips described above can be installed quickly and easily. A'horizontal strip can be applied to the upper edge and a vertical strip to one side edge of a p'fneltobfe installed. The lower edgeof the panel can then be seton theupper edge of a lower panel lprev iously installed and which edge .isjcovered by a horizontal strip. flhe uncovered upright edge of'the'panel will then gbe fitted with a previously installed vertical strip by bending outward the edge of the outer flange portion 7 sufficiently to receivethe panel edge. Such upright Ledge and the lower edge of the p nel. y h ncbe na edi Pl -3, 5 e a t upright edge of the panel may be nailed in place from the bottom up, making sure that the vertical strip which been applied to it is pushed 'ontojthe panel edge so thatits Web S abuts such panel edg e, Finally, the upper edge of the p anel willv be secured in place aiter making sure that the horizontal strip is pressed fully ow war o to t e upp r ed e. f r

While snchmethod of panel installation will be satisfactory, the strip material can be made available in long indeterminate lengths and his preferable for the separatrin s ris t ve sifew j i as po s e. AS h n; in FIGURE 1, it is preferred that the vertical joints inadjacen gwst fpa l f staggered s that-t ele h of each vertical separating strip will beapproximatelyequal to the vertical'extent'of apanel The horizontal separating jstrips can, however, extend -continiiously across a plurality of verticaljoints. Qonsequently, instead of app n a a p e of h t s p t het pp ed of each panel, a row of' panels can beapplied to the framing structure and s ecuredtemporarilyiin 'place by nailing them only part way up fromthe bottom. A continuous stripcan then be appliedto the'upperfedges of the panels in'the row andfthe upper edges of the panels then nailed to'the framing to secure such strip in place before the neXt higher row of panels is ap'plied.

It will be eyidept' that the spacing between the inner flanges 6 andthe outer'il'anges f7 -and9 sliouldbesuch 'as to enable a horizontal ;or vertical separating strip to be 'appliedtothe edge of the panel andretained-on it by the'slightclamping action'of the flanges. The strips are not secured to the panel edges, however, but are held in place simply by the flanges being clamped; between "the panel edges and-the framing structure to which they aresecured. Ifdesired,'andparticnlatlywhere the'length I 1 of the'panelsextends"-vertically, the panels cani besecnr'ed 'in placeby nailsdriven alongfl'onlytheir opposite-upright edges and such nails "samba-driven sufiicientlyclose to 'the panel'ed'ges so that theheads -ofr the nailswillbe :covere'd by the 'outer "flange portions 7 *of the upright separating"'strips.
