10 Claims.

My invention of a vertical structural interlocking panel system is an interlocking method for use in wall building construction, comprising (a) sheet metal panels and (b) vertical structural interlocking members or units. The wall panels or sections are of uniform size to permit interchange of panels, said panels or sections containing doors, Windows, blank wall panels and/or other wall elements. The panel or section is capable of housing wiring, heating and water pipes or ducts. The vertical structural interlocking members or units constituting upright framework elements of building construction, are the interlocking means for connecting or joining the panels or sections. My vertical structural interlocking panel system is for use in connection with metal, metal alloys and/or metallic compositions in which the vertical structural interlocking members or units constitute the supporting framework of said. building or structure, the vertical structural interlocking members or units acting as, or becoming, columns, studs or pilasters, capable of supporting all superimposed loads as commonly practiced in building construction, wherein said columns, studs or pilasters are sufficiently strong to support the weight of superimposed floors, roofs and walls in addition to the so-called live load.

It is an object of this invention to provide an improved wall section composed of a panel and a 30 pair of vertical structural interlocking members or units in which there are none of the usual joints or cracks exposed between sections or units and the finished effect of the exterior is that of a continuous structure of panels and 35 ornamental pilasters therebetween, having no noticeable joints or cracks and having or requiring no strips, cleats or moldings to cover said joints or connections.

It is among the objects of this invention toprovide a construction which is simple and convenient for manufacture, strong and durable, consisting of few parts and pleasing in appearance, especially by the avoidance of noticeable joints or cracks evident in conventional panel abutment, and as stated before, to avoid the use of a strip, cleat or molding usually employed to conceal the joint or connection between the abutting panels or sections.

. These several objects, together with others which will become apparent as the description progresses, are accomplished by the unique construction, combination and arrangement of few and simple elements hereinafter described and illustrated in the accompanying drawings, constituting an important component of this disclosure, and in which Fig. 1 is a perspective view, from the front or outside of a blank wall panel, with an upper portion broken away to show the L-strips and the longitudinal lateral flanges of the panel.

Fig. 15 is a horizontal section iew from above, with plates omitted, of various load hearing and ornamental vertical structural interlocking units similar to the one hereinafter described.

These units serve the same functions in connection with my invention, the only difference being the projections or ornamentation in the web partition of said units. These units, as well as combinations of these units, and others, are adaptable to my invention of a vertical structural interlocking panel system.

Referring to the drawings, the exterior vertical structural interlocking member I constituting one-half of the vertical structural interlocking unit (said unit described later in this specification) is formed preferably as shown in Fig. 2, and composed of five angles as shown at 2 for the purpose of strengthening and stiffening said member in vertical compression or stress, and further to be ornamental as an exposed exterior pilaster. Said member has outwardly disposed marginal lateral flanges 3 and an outwardly disposed angle or projection 4 in the web face of the vertical structural interlocking member. The stiffening or reinforcing angle or projection 4 is formed in the web partition of said member in such manner as to be ornamental on the exterior surface of said web and for the purpose of adding bearing strength to said member. The outwardly disposed marginal lateral flanges 3 of the vertical structural interlocking member are adapted to interfit or interlock in a channel or groove 5 provided in the abutting interlocking panel. The space across the edge of the outwardly disposed lateral flanges 6 is approximately the same width as the spaced relation of adjacent channel or groove walls 5 in the panel. Said vertical structural interlocking member is also provided with a plate I at the lower end or base of said member to provide a means of uniting the member to the foundation wall, sill or slab of the building or structure. Said member is also provided with a plate 8 at the upper end to provide a means of uniting said vertical structural interlocking member to the beam, joist or truss of said building or structure.

The interior vertical structural member is formed preferably as shown in Fig. 9 and composed of five angles as shown by 2 of Fig. 9 for the purpose of strengthening and stiffening said member in vertical compression or stress as previously described.

A vertical structural interlocking unit is composed of an exterior vertical structural interlocking member ID and an interior vertical structural member ll, described in the preceding paragraphs. The exterior and interior vertical structural interlocking members are placed in abutting web contact. so that said pair of vertical structural members have outwardly and inwardly disposed flanges 3 and are preferably joined together thereto at abutting web contact I2 by welding, brazing, soldering, or other methods in common practice by the trade. The two members have substantially uniform web surface contact l2, whereby to form a substantially H-beam stud with a vertical passage [3 in the web partition of said unit. Said unit or H-beam stud is capable of supporting all superimposed loads as commonly practiced in building construction, in addition to subserving its exterior ornamental function as illustrated in Fig. 12. The angles or projections 4 in the webs of the vertical structural members are for the purpose of increasing the bearing strength and to provide an increased stiffening effect in said unit or l -l-stud and to serve other purposes as required, namely expansicn and contraction, means of reinforcing, if required, by placing additional structural members or elements in said passage as shown at 30 in Figs. 7 and 8. Said passage I3 may also be used as a conduit or drainage duct.

The web partition or the projection in the web partition of the vertical structural interlocking unit permits considerable variation in a minor discrepancy due to ornamental variation and yet affords the desired structural strength in vertical compression. It is thought that such variation in the web partitions of the vertical structural units enters into the general scope of my invention and need not be described in detail. Fig. 15 illustrates a few of the possible variations in the web partitions of such vertical structural units.

The method of constructing panel units includes the bending or die stamping a rectangular blank of sheet metal to form continuous lateral flanges l4, l5 and 16 substantially at right angles to the face of said panel. The longitudinal marginal lateral flanges I4 are bent substantially to corresponding or equal width best illustrated by Fig. 5, while the horizontal lateral flanges are bent to unequal width. The longitudinal lateral flanges of the panel l4 or of such depth or width as required to overlap and conceal the outwardly disposed flanges 3 of the exterior vertical structural interlocking member. The horizontal lateral flange H3 at the base of the panel is of such depth or width as required to provide a suitable base connection to foundation wall, sill or slab of said structure. The horizontal lateral flange H5 at the upper end or top of the panel is of such depth or width as required to form a suitable cap or coping for said panel. By welding an L-strip 9 to the interior face or plane of the panel in opposed spaced relation to the longitudinal lateral flange l4 of said panel, a longitudinal channel or groove 5 is thereby formed. The L-strip 9 extends on both longitudinal sides from the base of the panel to the top of the panel best shown by Fig. 9. Said L-strips 9 serve to stiffen the face or plane of the panel and become a part of the framework of the panel. The channels or grooves 5 are for the purpose of receiving and concealing in a snug fit the outwardly disposed flanges 3 of the vertical structural interlocking member or unit, positively interlocking the panel and the aforementioned structural member or unit together against lateral displacement. These interlocking joints or connections also afford a reasonable amount of flexibility against expansion or contraction of the panels so as to maintain proper waterproof characteristics under the usual variations in weather. The L-strip 9 extends inwardly at substantially right angles to the interior face or plane of said panel to approximately an equal distance as the edge of the inwardly disposed flange 3 of the vertical structural member or unit I8. In other words, the inwardly extending edge of the L-strip 9 should be approximately flush with the edge of the inwardly disposed flange 3 of the vertical structural member or unit best shown by l8 of Fig. 6. The abutting joints between the L-strip 9 in the panel and the inwardly disposed flange 3 of the vertical structural member or unit are then united theretogether by welding, riveting, nuts and bolts, sheet metal screws or nails, or otherwise suitably connected in the approved present day practice. A strong construction is thereby provided, easy to assemble, and using a minimum of metal.

of the hollow metal post in both the abutting and The'panel construction and elements are substantially the same on both longitudinal sides or edges of said panel, each interior side or edge of the panel is provided with the heretofore described L-strip 9, and in combination with the longitudinal lateral flanges I4 of the panel the channels or grooves 5 are thereby formed in which to receive in a snug flt and conceal the outwardly disposed flanges 3 of the adjoining vertical structural interlocking member or unit, said L-strip abutting and uniting with the iniwardly disposed flange of the vertical structural member or unit as shown in Fig. 6 thereby producing tight joints between the L-s'trip 9 and the inwardly disposed flange 3, it being noted that in this construction a perfect joint is obtained in a strong, durable and inexpensive manner. The welding, riveting, nuts and bolts, or other means of connection are entirely concealed, while the exterior interlocking joint or connection is such that no cracks or joints are evident except by very careful examination. The assembly or erection of panel sections may be made on the job by comparatively unskilled labor and at low cost.

In connection with the panel, as already described, I provide certain auxiliary structural elements as required. My vertical structural interlocking panel system is especially adapted to the use of the so called pre-fabricated interior wall panel materials. It may however be used in connection with plastic wall materials of the plaster type. A channel iron of suitable size [9 is used in connection with fastening elements to clamp or draw the base of said panel in close and rigid contact to the foundation wall, sill or slab of said building or structure. Suitable insulation (not shown) may be applied to the under surface or interior of said panel. Panels or panel sections may be of the blank wall type, as hereinbcfore described, or said panels or panel sections may contain window, door and/or other wall elements. As stated heretofore, a panel wall section or unit is capable of housing wiring, heating and water pipes or ducts.

The corner post construction, Fig. 14, used in connection with my vertical structural interlocking panel system is composed of a hollow metal post 20 completely enclosed on two adjoining sides by a sheet metal cap 2|. The hollow metal post and the sheet metal cap 2| are welded theretogether at abutting web contact. The metal cap 2! extends or follows the contour of the post 20 on the two remaining sides in such manner as to form and become flanges 22 at its respective lateral edges, said flanges 22 spaced an approximately equal distance from the wall of said metal post 20 as the space across the edge of the flange 6 of the exterior'vertical structural interlocking member or unit, thereby forming a channel or groove 5 on both adjoining sides of the metal post 20 in which to receive and concoal in a snug fit the outwardly disposed flange 3 of the abutting vertical structural interlocking members or units. The inwardly disposed flanges 3 of the abutting vertical structural interlocking members or unit abut the hollow metal post 28 and means unite the hollow metal post 20 to said flanges 3, thereby forming an interlocking weather-tight joint of strong construction. This assembly is best shown in Fig. 11. It will be noted that the corner post construction as described above, being an addition to the wall panel sections, will increase the horizontal wall area by approximately onehalf the width interlocking directions, and in some instances thereby causesthe building to be out of alignment with respect to truss, joist or beam supports, said supports being the heretofore described verticalstructural interlocking unit Fig. 2. In some instances this type of corner post may be desirable but where it is found impracticable I have an alternate (corner post construction in which there is substantially no gain in the horizontal wall area, Fig. 13, and which does not cause the building to be out of alignment in truss, joist or beam support. In this modified corner construction shown in Figs. 12 and 13 the sides of the corner post 20 are equal in width to flanges 3 on the exterior structural members and abut suchv flanges, or in other words, the hollow metal post 20 is approximately the same width on each abutting side as the abutting surface of the flanges 3 of the exterior vertical structural interlocking members. The inwardly disposed flange 3 and a portion of the web 4 of Fig. 13 of the interior vertical structural member is cut off or removed in order to allow the inwardly disposed flange 3a of the adjoining corner vertical structural interlocking member or unit to abut the back of the exterior vertical member 31). An L-strip 4a is then united to the interior corner thus formed by abutment of the vertical structural members Fig. 13, reinforces the corner construction and also overlaps and reinforces the joint caused by the removal of the flange 3 and a part of the web of the interior vertical structural member 4.

Among the principal advantages of the building system, as above described, is the simplicity and ease of erecting building walls in a wide variety of architectural designs. After thefoundation is prepared the panel sections Fig. 9 may be readily and quickly fitted together with a minimum of cost and labor. The vertical structural interlocking members or unit is intended for supporting heavy floor loads or the like in addition to subserving its ornamental function as an exposed pilaster or column.

While the preferred forms of my invention have been shown and described, it is not intended that the foregoing be interpreted as limitative as changes may be made without conflicting with the scope of the hereto appended claims.
