CHARLES W. ATTWOOD pauw-m I ATTORNEYS 2,990,650 ROOFING.

Charles w. Auwbod; 4118 s. Wayne Road, Wayne, Mich.

Filed Apr. 29, 19 57, Ser. No. 655,808 Claims. (Cl. 50-212) 'Thepresent invention relates to roofing for buildings and more specifically to a form of roofing that is quickly and easily applied.

Among the objects of the invention is to provide mean for quickly. and efiectivelysecuring the :roof covering to the supporting means. I

Another object is to provide securing means, permitting the application. ofthe. .coveringfrom rolls and securing the'latter atfrequentlocations, without the use of nails o'rother means penetrating the,covering material.

Anothersobject is to provide a roof structure that permits the escape of any gaseous or vaporous material which may be trapped under the impervious roofing.

Another objectis a roof which may be quickly, easily and permanently repaired, if repair should become necessary.

Other objects and advantages will readily occur to those skilled in the art upon reference to the following description and the accompanying drawings in which FIG. 1 is a plan view, more or less diagrammatic, of a roof supporting frame for a roof of the present construc tion.

FIG. 2 is a sectional view taken for example on line 22 of FIG. 1, and showing the roof structure.

FIG. 3 is an exploded view of the structure of FIG. 2.

FIG. 4 is an exploded view showing a slight modification.

The present invention relates specifically to roofs applicable to and particularly advantageous with structures such as are shown in my prior application Serial No. 481,748, filed January 14, 1955, for Building Construction, and now abandoned.

As described and claimed in said prior application, a structure is built up of a multiplicity of identical metal channel members fixed together in such fashion as to produce a roof supporting portion consisting of rectangular pyramidal forms some of which are erect and some are inverted and all are so related that each erect pyramid has its slanting edges in common with a slanting edge of an adjacent inverted pyramid. The resulting structure has the rectangular bases of the pyramids in parallel planes connected together by the slanting members forming the edges of the pyramids.

The metal channel members used in this structure are preferably of a form appearing on the market under the name of Unistrut and are metal channels rectangular in cross section having their side walls turned in at right angles and the edge portions of such turned in walls again turned in at right angles and the edge portions of such turned in walls again turned in at right angles and sharpened or double beveled. This produces a rectangular channel member having along one face a slot provided at its edges with substantial inwardly projecting flanges.

In the structure so produced, the elements constituting the rectangular pyramid bases are so arranged that the slotted face opens outwardly.

As indicated in FIG. 1 of the drawing, the roof frame members are arranged as rectangles which, in the case above referred to, are square, but it should be understood that other rectangular forms may be used if desired.

Each of the frame members 10, as mentioned above, shows in cross section the form shown in FIGS. 2 and 3, and is arranged with the slot 10A opening upwardly.

In producing the roof, a panel 12 of substantially rigid material, such as plywood, asbestos composition board or other material suitable from the standpoint of strength and stiffnessjis placed over the rectangular areas 11'. The. panels 12 are of such size as to cover the areas and have their edges rest upon the frame members 10 without covering the slots 10A.

.The panels 12 are then fixed in place by the batten strips 15 which consist of spring metal formed to produce in sectional view a substantially flat head portion 15A provided with spring tongue portions 15B each of which has an outwardly extending rib 150 so located that it: will underlie the edge of a flange 10b ofa member 10 when the strip is inposition. The head portion 15A will extend over and rest upon the edges of two of the panels 12 as shown in FIG. 2.

When the panels 12' and strips '15 are 'in'place, the

exposed upper faces 16 of'the strips 15 are coated with a suitable adhesive, and the cover material 17 is applied and pressed against the adhesive coated batten strips and ad-- along with its protective film 16B,

In producing the roof above described, the covering sheet material 17 preferred is partially cured neoprene which will adhere very strongly to itself if allowed to, and may be obtained in rolls with one face of the sheet covered with a removable and disposable film to prevent sticking.

In applying the sheet 17, the protective film will be removed and the neoprene pressed against the adhesive coating on the batten strips or upon the neoprene strips 16A after, of course, removing the film 163.

The adhesive 16 is preferably made by dissolving neoprene in a suitable solvent.

While it is proposed to cause the adherence of the cover 17 only to the batten strips 15, one or more spots of the adhesive may be applied to the panels for additional adhesion if desired. However, the cover 17 should, for the most part, be left unadhered so that any water-vapor may travel to the bottom strips and escape down around the edges of the panels 12.

I claim:

1. Roof structures comprising a frame consisting of metallic members each provided with a longitudinal slot in its upper face of less width than the members, substantially rigid panels having their edges resting on marginal portions of said frame members alongside of said slots, batten strips coacting with said slots fixing said panels in position said batten strips consisting of laterally extending portions overlying the edges of said panels and having spring tongues thrust into said slots and maintaining said batten strips in position and a weather resistant cover material extending over said panels and batten strips and cemented only to said strips whereby vapor formed between the panels and the cover material will not remain trapped in place.

2. Roof structures comprising a rectangular frame consisting of metallic members each provided with a longitudinal slot in its upper face of less width than the members, substantially rigid panels having their edges restmg on marginal portions of said frame members alongside of said slots, batten strips coacting with said slots fixing said panels in position said batten strips consisting of laterally extending portions overlying the edges of said panels and having spring tongues thrust into said slots and maintaining said batten strips in position and a sheet of partially cured neoprene extending over said panels and batten strips and cemented only to said strips whereby vapor formed between the panels and the cover material will not remain trapped in place.

3. Roof structures comprising a rectangular frame consisting of metallic members each provided with a longitu- Patented July 4, 1961 dinal slot in its upper face of less width than the members, substantially rigid panels having their edges resting on marginal portions of said frame members alongsideof said slots, batten strips coacting with said slots fixing said panels in position said batten strips consisting of laterally extending portions overlying the edges of said panels and having spring tongues thrust into said slots and maintaining said batten strips in position and a sheet of partially cured neoprene extending over said panels and batten strips and cemented only to said strips whereby vapor formed between the panels and the cover material will not remain trapped in place, there being an intermediate layer of said neoprene between the strips and said sheet.

4. A roof structure comprising a framing member having an upper supporting surface, panel members having substantially parallel edges spaced apart and supportingly carried on said framing member supporting surface, a batten resiliently secured to said framing member intermediate said panel members and comprising a substantially flat closure strip covering said panel edges and the space between said panel edges, a layer of adhesive material disposed only on the upper surface of said closure strip, and a weather resistant substantially air-impervious cover material extending over and carried by said panels and said batten and secured only to the upper surface of said closure strip whereby to avoid entrapment in place of vapor bubbles formed between the cover material and the panels.

5. A method of constructing roof structures, comprising constructing a framing support, placing roof panels onsaid support, resiliently securing batten strips to said support to close the spaces between panel edges and to permit escape of entrapped moisture, applying adhesive only to the top surfaces of said batten strips, and covering said panels and batten strips with a weather resistant cover whereby said cover will be supported by said panels and strips but will be secured only to the batten strips.
