JOHNSTON INSULATED WALL CONSTRUCTION 2 Sheets-Sheet 2 Filed Jan. 8, 1962 Uted St 3,19S,6 ll JdULATED WALL CGNSTRUQTKQN Charles Richard .lohnston, 8% E. .l'aclsson Blvd, Qhicago, Ill. Filed Jinn. 8, 1962, Ser. No. 164,707 5 lairns. ($1. 189-34) This invention relates to a new and useful improvement in an insulated wall construction and more particularly to a self-supporting wall construction having an insulating metal bonding core.

A principal object of this invention is in the provision in a Wall construction of this character of an arrangement of parts comprising exterior and interior wall panels bonded together by an inner core of synthetic insulating material so as to form an integral self-supporting wall section.

A further object of this invention is in the provision in a wall construction of this character of an arrangement of parts wherein the exterior and interior wall panels are provided with means which afford vertical stability and rigidity thereto so the same are self-supporting and capable of withstanding a great degree of stress and strain, yet requiring a minimum of thickness and Weight.

Yet another object of this invention is in the provision in a wall construction of this character of a means for providing an enclosed space between an exterior wall panel that is rigid and self-supporting and an interior wall panel that is also rigid and self-supporting and the filling of this enclosed space with an insulating wall panel bonding material which then incorporates each of these panels into a solid core wall construction.

Still another and equally important object of this invention is in the provision in a Wall construction of this character of an arrangement of parts that includes an inner insulating core and having an interior metallic Wall surface that provides nail retaining grooves.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:

FIG. 1 is a detailed sectional View or" the wall construction of this invention.

FIG. 2 is a front elevational view of the wall construction of this invention showing in dotted lines the structural formations provided by each panel of the wall structure.

FIG. 3 is a side elevational view of the wall construction of this invention.

FIG. 4 is a detailed sectional view similar to FIG. 1 but showing a modified form of construction.

FIG. 5 is an elevational view of one of the sectional units of the exterior wall panel, and

FIG. 6 is an elevational view of one of the sections of the interior wall panel.

It is the purpose of this invention to provide an insulated wall section that is of a minimum thickness and weight, yet self-supporting and provided with a great degree of vertical stability and rigidity. By this invention there is provided an insulated Wall that may be utilized in building construction, refrigerated freight shipping vehicles, sa well as general appliances that require an insulated wall.

A wall construction of any size or shape may be achieved through the employment of this invention without departing from the spirit and objects hereinbefore set forth. A partial wall section embodying this invention is generally shown as at It) in FIG. 1. This Wall section comprises a series of aligned exterior face plates 11.

3,195,599 Patented July 26, 1965 Each of these face plates 11 is provided at opposite ends with inwardly extending flanges 12. The corresponding flanges 12 of each of the face plates 11 are adapted to abut one another and be welded together so as to form a substantially flush exterior wall surface.

The inner surface of each face plate 11 intermediate the end flanges 12 thereof is adapted to lie in facial abutment with the outer surface of a plurality of exterior Wall panels generally shown as at 13. These wall panels 13 comprise a series of interconnected sectional units 14; one of which is illustrated in FIG. 5. Each of these exterior wall sectional units 14 includes a substantially flat elongated body 15. The body 15 of each unit 14 terminates at each end into diverging flanges l6 and 17 with each flange 16 and 1'7 having its respective end portion 13 and 19 angled in opposite directions out of the plane of its respective flange. Thus each of the flanges 16 and 17 provides a V-shaped end which is oiiset with respect to the longitudinal length of the body 15. It should be noted that flange lid is of a length slightly greater than flange 17 and thus its V-shaped end is displaced further inwardly of the longitudinal plane of the body 15, a distance equal to that indicated at A in FIG. 5, this for a purpose hereinafter made apparent.

When the exterior wall panel 13 is by necessity formed into an extensively Wide unit as seen in FIGS. 1 and 5 only the extremities thereof need be formed for interlocking engagement as hereinafter explained. When such a wide panel is formed, however, there should be formed intermediate the interconnecting ends parallelly extending equally spaced V-shaped indentures such as is shown as at 2% in FIGS. 1 and 5. This structural configuration adds stability and rigidity to each of the Wall panels 13 to make the same self-supporting.

An interior wall panel 21 is provided in spaced relation with respect to the exterior face plates 11 and exterior wall panels 13. This interior wall panel 21 comprises a plurality of prefabricated self-supporting wall sections 22 as shown in FIGS. 1 and 6. Each of the interior wall sections 22 comprises a flush body portion 23. This interior flush body portion 23 is formed to present throughout its longitudinal length a series of transversely extending nail receiving grooves 24. These nail receiving grooves 2 are formed by having the body 23 constructed so as to provide a substantially triangularly shaped impression having a base 25 which extends in a parallel plane to the flush surface of the body 23. The opposite legs 26 of such triangularly shaped impression converge to provide a restricted throat 2'7 for receiving and retaining a nail or the like inserted into the nail receiving groove 24. The opposite longitudinal edges of each of the interior Wall sections 22 are so formed so as to provide only one complementary leg 28 and 29 for each of the endmost nail receiving grooves 24. Each of the complementary legs 23 and 2? provides a base portion 39 and 31 which extends in a parallel plane with respect to the flush body 23. The complementary leg 28 is of a length slightly less than the opposite complementary leg 2? so that the base 34 of such leg 23 is oflset a distance equal to that indicated as B in FIG. 6.

The arrangement resulting from the construction of the interior wall panel 21 is that each interior wall sec tion 22 is inner-connected by having the base 31 carried by the leg 29 at one edge of the interior wall section 22 placed over and in facial abutment with the base 30 of the associated leg 28 carried by the next succeeding interior wall section 22. As viewed in FIG. 1 the wall section 22 shown in its entirety is connected to associate wall sections 22 in the manner just described so that there are presented continuous equally spaced nail receiving grooves throughout the length of the entire interior wall panel.

the nailable interior wall panel 21. the construction of a wall, the section units of which each As shown in FIG. 1, the exterior face plates 11 and the exterior sectional units 14 of the exterior wall panel 13 are related to the interior wall panel 21 in such a manner that the V-shaped ends are adapted to project inwardly toward the interior wall panel 21 intermediate the nail receiving grooves 24 of such interior wall panel 21. The flange 17 and its angular end 19 is placed over and in facial abutment with the flange 16 and its angled end portion 18 of the successive sectional unit 14. From the foregoing, it is clear that the exterior wall 13 as well as the interior wall 21 are self-supporting. The two Wall panels are held in vertical spaced alignment and the space therebetween is filled with synthetic insulating material 32 in the form of polyurethane. This insulating material will bond itself to the inner surface of the exterior wall panel 13 as well as the inner surface of the interior wall panel 21 and thus become an insulated core bonding together the wall panels into an integral structure as seen in FIG. 1.

In the event that there is desired an interior wall surface that is flush rather than one presenting nail receiving grooves, such interior wall may be formed in the manner shown in FIG. 4.

In FIG. 4 the interior wall 21' is formed in the same structural manner as the exterior wall 13 shown in FIGS. 1 and 5. This interior wall 21 is installed in place of In FIG. 4, I show have V-shaped end portions provided with over-lapping flanges 18' and 19' thus excluding the necessity of having an intermediate V-shaped indenture 20 as shown and described in FIGS. 1 and 5.

From the foregoing, it is evident that this invention provides an insulated wall construction that is self-supporting requiring the minimum thickness and weight while at the same time affording a great degree of vertical and horizontal stability and rigidity.

While I have illustrated and described the preferred form of construction for carrying my invention into eifect,

this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do

not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
