15 Claims.

This invention relates to enameled metal wall construction of a type particularly suited for use in the erection of new, or the remodeling of old buildings, homes, filling stations, and the like.

In my copending application entitled Enameled metal wall construction", Serial No. 742,- 029, filed August 30, 1934, there is disclosed a construction wherein the enameled metal plates are prefabricated on insulation board backing so as to provide individual panels of metal veneered board that can be readily assembled in the construction of internal or external walls. Since there is no interlocking of the panels with each other, any panel can be quickly and easily removed from the face side without disturbing any of the adjacent panels.

The metal panels, which usually become warped at the high temperatures employed for burning on the enamel, are cemented under high pressure to rigid insulating boards, both for the purpose of pressing the enameled metal to straighten it out and also to eliminate the tendency of the metal to buckle under climatic conditions. Furthermore, the heavy insulating boards not only prevent sweating of the metal but also act as sound deadener and heat insulation. In wall construction, these panels are supported in spaced relation and the resulting joints are all caulked, so that no metal touches metal and the edges of the panel are protected by a waterproof caulking compound. All of the edges of the enameled metal panels are, at the same time, protected against rusting by the caulking compound.

The present invention contemplates the use of metal veneer panels of the type described, but of an improved construction, in the erection of external or internal walls of porcelain enameled metal. The-invention also contemplates the use of improved retaining strips and cover trim of a uniform, standardized form and appearance, as well as the use of standardized base and ceiling molding formed from rolled or stamped metal.

It is therefore an object of this invention to provide a metal veneer wall construction that can be simply and inexpensively erected owing to the fact that the elements of the wall are largely prefabricated and are of uniform, standard design so as to be interchangeable.

It is a further important object of this invention to provide an enameled metal wall construction in which prefabricated enameled metal panels of standard size and shape may be used in the construction of the side walls and similar but slightly differently constructed metal panels may be used in the ceiling.

Other and further important objects of this invention will be apparent from the disclosures 6 in the specification and the accompanying draw- This invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described. 10

As shown on the drawings:

. The reference numeral l0 (Fig. 1) indicates 30 generally a wall of porcelain enameled metal embodying the principles of my invention. The wall I0, as shown, is an internal wall but the same general construction applies to external walls as well. The wall I0 is joined by another 35 side wall ll of similar construction and is provided with a ceiling 12. The wall H is separated by a space l3 from a wall H of similar construction butoppositely spaced, the walls II and It thus forming a complete wall partition, such as 40 would be used between two adjoining rooms.

The wall l0 comprises a supporting framework of wood formed of vertically extending studding l5 and horizontally extending stringers I6 and a base furring strip 58. The studding and stringers 45 are put up in the usual way at properly spaced intervals and joined together to make a rigid supporting framework for enameled metal panels I1. The stringers I! may be formed integrally, or as best indicated in Fig. 2, may be provided with separate strips l8 secured'thereto and extending along one, of the broad faces of each stringer. The strips l8 are formed with a longitudinally extending central groove l8, which may suit- 55 The metal veneer;22 ispreferablyprovided-with a porcelain enamel surface, which may bei'ozf any desired color and which may be either highly glazed, or have a matt or rough surface.

Each metal panel 11 may have flanges 24 and 23 extending along opposite edges, which may be either the short or long edges, as desired, but not both. These flanges 24 and 23 lie beyond the end edges 23 and 21, respectively, of the insuiation board 21 by a distance suilicient to permit the flanges 24' and 23 to extend into the grooves I 9 and be embedded. therein in the caulking 23. The caulking also extends between all of the Joint surfaces as at 23 and 29 between the panels l1 and the strips l3 and studdins' II. x The dimensions are. such that the flanges 24 and 23 are spaced apart and also from the body of the strips I3, whereby the metal of the panels is free to expand and contract.

The other edges of the metal veneer on the panels I 1 are not flanged but extend somewhat beyond the corresponding edge of the insulation board, as indicated at 33 Fig. 3). These extended edges 30, when the panels are assembled, are in spaced relation overlying the horizontal stringers i3. Said stringers i3 have strips 3i extending along their broad working faces, the strips 31 being either integrally formed with the stringer or separately formed and attached thereto. Retainer strips 32 are positioned along and in overlapping relation to the extended edges 33 and are secured in place by means of screws or nails 33 that are threaded into the strips 3|. The space inside of the retainer strip 32, as well as the entire Joint, is then filled with a waterproof caulking compound that remains plastic over an extended period. A composition containing tung 'oil and asbestos makes a satisfactory caulking compound.

The retainer strip 32 may be formed of stamped or rolled sheet metal with reversely rounded lateral edges 34 that are adapted to be brought into snug engagement with the extended metal edges 30 by threading home the screws 33.

An outside cover trim 35 is so constructed as to be readily snapped in place over the rounded lateral edges 34 of the retainer strips '32. Said cover trim 35 may suitably be made of stainless steel or other non-corroding metal or metal alloy of pleasing surface characteristics. Each cover trim 33 is provided with reversely bent lateral edges 33 which, because of the inherent resiliency of the metal itself, can be snapped over the rounded edges of the retainer strips 32 and held in place thereon without other fastening means.

In making the ceiling i 2, panels 31 are used, which are similar in general construction to the panels l1 but slightly different therefrom in that the metal veneer 38 is provided all around with side flanges 39 that extend over the end edges of the insulation board backing 43. The comer edges of each panel 31 are cut away, as at M, to provide a space 42 between the corners of adjacent panels for the insertion of fastening means, such as the screw 43. Said screw 43 carries at its headed end a disk or washer 44 which overlies aordsss substantial corner portions of the assembled f panels. The disk or washer 44 may take any desired ornamental form or design, and may even be made of glass, since the weight of the panels 31 is comparatively little.

As best shown in Fig. 6, the ceiling panels 31 are sustained solely by means of the fastening means 43 from the stringers 43, except for the panels next adjacent the side walls I i The tops ,of saidside 'walls' It comprise 'liorizontally' extending wooden strips 43 which are either formed integrally with or secured to stringers 41 forming a part of the supporting frame. Each strip 43 is provided with a ceiling molding strip 43 formed from stamped or rolled sheet metal and having a generally angular cross section. One of the webs 43 o'f'said ceiling molding 43 extgnds along and is secured'to the upper face of the strip 43, as by means of screws 33. The outer web SI of said ceiling molding 43 is spaced from and parallel to the inner plane surface of the strip 43 and is provided with a reversely bent flange 52 also parallel to said face. Although the flange 52 is normally resiliently held against the face of the strip 43, prior to assembly of the side walls i l, during assembly the extended marginal portion 33 of the metal panel 54 is inserted therebetween. The space between the web iii of the ceiling molding 43 and the strip 43 is filled with caulking 35, as are also other portions of the Joint. There is thus formed a water tight joint. 4

The ceiling panels 31 adjacent the side walls Ii rest directly upon the leg 49 of the ceiling molding 43, as indicated at 31 (Fig. 6). By virtue of the fact that no fastening means are used but merely a surface to surface contact, free relative movement between the contacting parts due to contraction or expansion is permltted- The side walls H are supported upon base furring strips 53 (Figs. 3 and 4) which have strips 59 integrally formed therewith or secured thereto. To each of said strips 53 is secured a base molding 33 of generally similar design to the ceiling molding 43. Said base molding 30 has its horizontal web 31 secured to the strip 59 by screws or other attaching means 32. An upright web 33 extends substantially parallel to and spaced from the front plane face of the strip 33 andis provided with a reversely bent flange 34 that is resiliently urged toward said plane face. The space between the web 33 and the strip 59 is filled with a caulking compound 35. The whole assembly of base furring strip and molding is preferably prefabricated in proper lengths.

When the metal veneer panels l1 are mounted in place, the lower extended edges 33 of the metal veneer are inserted into the space formed between the flange 34 and the face of the strip 59, the flange 34 thereafter, because of the resiliency of the metal, pressing firmly against the metal veneer. This type of molding permits greater tolerances in the dimensioning of the panels.

It will be understood that both the base and ceiling molding may be prefabricated with their corresponding furring strips or the like. The vertical studding l3 and the stringers I6 are likewise prefabricated and cut to size for the particular job for which they are to-be furnished. In the erecting of the wall structures, therefore, it is a simple matter to flrstput up the supporting frame-work of studding, stringers, furring strips, and the like, and then buildup the fluished wall by inserting the individual wall panels I! in place in the framed openings. After all joints have been properly caulked the retainer strips and cover trim are positioned in 6 place. In the finished wall structure, the edges of the metal veneer are in spaced non-interlocking relation and protected against rusting by being embedded in the caulking compound. Each panel is readily and quickly removable, upon 10 removal of the cover trim and retainer strip. without disturbing the next adjacent panel.

The ceiling panels 31 are secured in place by means of fastening devices 43 and 44 with clearances between adjacent metal veneers to allow for expansion and contraction. I I am aware that many changes may be made and numerous details of.construction may be varied through a wide range without departing from the principles of this invention, and I. therefore. do not purpose limiting the patent granted hereonotherwise than necessitated by the prior art.
