' 3 Claims. (01.189-34 invention relates toa new and improved securing means for mounting insulating or wall panelsupon a wall or ceiling, and more particularly to the novel construction of said securing means.

An object of the present invention is to Provide a novel securing mean adapted for use in mounting wall panels in position against the inner surfaces of the studding or uprights of a wall or ceiling, and whereby such panels may b expeditiously secured'thereto without the use of bolts, screws, nails, or other similar fastening means.

A further-object is to provide a novel channel structure comprising oppositely facing channels each adapted to receive an edge of an insulating panel, and saidchannel structure being so constructed as to provide a leakproof joint between the contiguous edges of the'adjacent panels.

A further and more specific object of the invention is to provide a channel structure formed of sheet metal and including a main part of substantially Z-bar cross-section, comprising oppositely disposed flanges connected together by a central connecting portion whereby said flanges are disposed in spaced. parallel planes, and suitable angle irons being secured to opposite sides of said central portion and each having a leg disposed in parallel relation to one of the flanges of the Z-bar and cooperating therewith to provide a channel, and whereby said angle irons and Z-bar provide a double channel structure in which the channel arev arranged in back-to-back relation and are connected together by a leak proof joint.

A further object is to provide a novel clip for securing wall panels to the inner surfaces of a plurality of uprights or studding, each clip being formed from a single piece of sheet material, having its body bent longitudinally whereby said quantity production at small cost, and greatly facilitates the operation of securing the wall panels in position against the studding without the use of screws or bolts.

Other objects of the invention will appear from the following description and accompanying drawings and will be pointed out in the annexed claims.

In the selected embodiment of the invention herein disclosed, there is illustrated in Figures 1,

2 and 5 for purposes of disclosure, a portion of a building wall similar to the one shown and a scribed in my co-pending application, Serial No. 424,277, filed December 24, 1941. The wall, as best shown in Figure 2, comprises a plurality of uprights or studding 2, which, as shown in Figure 5, are arch-shaped whereby they may also constitute the rafters for supporting the roof of the tion of the securing clip which may be made in 66 building, It is to be understood, however, that the invention is equally applicable to buildings in which the studding 2 extend vertically the height of the walls, and support suitable rafters, not shown, which provide the supporting means for the usual roof covering, as is well known. The invention, however, is'particularly applicable to buildings of the general type shown and disclosed in my above mentioned pending application.

The uprights 2 are shown of channel cross-section and are suitably supported upon a foundation 3. Suitable wall plates 4 are secured to the outer surfaces thereof by suitable clamping channels seated against the contiguous edges of adjacent wall plates and secured in position by bolts 6, received in apertures provided in the uprights 2. The joints between adjacent wall plates which i all between the studding 2, are supported by similar clamping channels 5, having strap like plates 1 arranged in clamping relation thereto by bolts 8. The contiguous edges of adjacent wall plates are clamped between the channels 5 and straps I as shown in Figure 2. All of the above described construction is shown and described in detail in my heretofore mentioned pending application, and therefore need not be further described herein.

In all-metal buildings of the type herein referred to, it has been found highly desirable to insulate the wall and ceiling or roof to prevent the conduction of heat or cold therethrough. To thus insulate the walls, I propose to secure a plurality of insulating boards or panels 8 against the inner surfaces of the uprights or studding 2, which panels, when the building is completed, may constitute the inner wall surfaces of the walls and ceiling of the building.

It is important that the insulating panels 8 be secured in position against the uprights 2 whereby the joints therebetween will be substantially leak proof, thereby to prevent the infiltration of cold or warm air through said joints. To thus secure the contiguous edges of adjacent panels together in leak proof relation, I utilize a double channel structure, generally designated by the numeral l9. This double channel is composed of three parts, all formed of sheet metal, and consists of a main body portion of substantially Z-bar cross-section, designated by the numeral 9, and two angle irons, generally designated by the numerals H and I2. The oppositely extending flanges I3 and |4 of the Z-bar 9 are connected together by a central connecting portion l5, clearly illustrated in Figure 8, whereby the flanges I3 and M are disposed in spaced parallel planes, as clearly shown in Fig-' ures 8 and 9.

The angle irons II and I2 are adapted to be secured to the central connecting portion l5 of the Z-bar 9. To thus secure the angle irons II and I2 to the Z-bar, the legs l8 thereof are seated against opposite sides of the central connecting portion Hi and secured thereto by suitable means such as welding. When the angles are so secured to the Z-bar, the oppositely extending webs l6 and ll of the angles H and I2, respectively, cooperate with the flanges l3 and H of the Z-bar to provide a double channel structure in which the channels A and B are oppositely disposed and connected together by a leak-proof joint.

The channels l9, as will be noted by reference to Figures 1, 3, 4 and 5, are adapted to connect together the contiguous edges of adjacent panels 8, both vertically and horizontally. The horizontal channels preferably extend the full length of the panels and may have their ends abutingly engaged at spaced intervals along the length of the wall structure. The vertically disposed channels are shown cut slightly shorter in length than the overall width of their respective panels, whereby the ends thereof will seat against edges of the horizontal channels l9, as clearly illustrated in Figure 1.

Another important feature of the invention resides in the novel means provided for supporting the panels 8 in position against the uprights or studding 2. To thus secure the panels in position, a plurality of clips, generally designated by the numerals 2| and 22, are provided, which are preferably made right and left hand, as clearly illustrated in Figures 6 and 7. Each clip is formed from sheet material, preferably metal, and has an elongated body portion which is bent along a line 23 whereby the body of each clip is substantially right angular in cross section, and is composed of webs 24 and 25, The web 24 of each clip 2| or 22, is formed at one end with a downwardly extended tongue 26, and its complemental Web 25 is formed at the opposite end of the clip with a laterally extending tongue 21. Like parts of the clips 2| and 22 are indicated by like numerals.

When insulating or wall panels are to be ems bodied in a wall, a single channel 28 is preferably fitted over the lower edge of the bottom panel, as shown in Figure 5. The channel 28 may be seated upon the horizontal leg 29 of an angle 3| secured to the foundation 3, and serving as a means for anchoring the lower ends of the uprights 2.

A double channel |9 has its downwardly facing channel B fitted over the upper edge of the lower panel 8, and the next succeeding panel 8 is then seated in the upwardly facing channel A, as shown in Figure 5. The lower panel 8 is then secured in position by inserting the tongue 26 of a clip 2| into the upper channel A of the double channel l9, and the laterally extending tongue 27 at the opposite end of the clip is inserted between the outer surface of an upright 2 and the wall plate 4, it being necessary in some instances, to loosen the bolt 6 sufficiently to permit insertion of the tongue 21 between the parts, as shown at the left hand side of Figure 2. When the clip is thus engaged with the channel I9 and the upright 2, the panel 8 is securely retained in position against the inner surface or edges of the upright 2.

Similar clips are utilized for supporting the intermediate portion of the panels 8, as shown in Figure 2. These clips have their tongues 25 engaged with the channels H3, in a manner similar to the ones at the left hand end of Figure 2, and the laterally extending clip 21 thereof is fitted between the wall plate 4 and the strap like clamping member I, as shown. At the right hand end of Figure 2 the panel is shown secured to the upright 2 by a clip 22, of the type shown in Figure 7. The clips 2| and 22 may be inserted at any point where desired, as the tongues 26 thereof may be inserted in one of the horizontal channels and the tongue 21 be received between the wall plate and studding 2, or between the wall plate and the clamping member I.

By the use of the clips 2| and 22, and double channels IS, the insulating panels 8 may readily and quickly be mounted in the wall with a minimum of effort and without the use of bolts or screws. By concealing the horizontal and vertical edges of the insulating panels or boards by inserting them in the double channels herein disclosed, the panels will be uniformly and rigidly supported over the entire area of the wall, and it will also be impossible for cold or warm air to pass between the opposed channels A and B of the double channels ll. a

I have found from actual experience, that the simple clips herein disclosed, used in combination with the double channels 19, greatly facilitate the installation of the insulating panels or boards 8 in the building walls and ceiling.

The clips 2i and 22 are extremely simple and inexpensive in construction, and may be made in large quantities by stamping and forming dies, as is well known.

By insulating the walls and ceiling of a building with insulating panels, as herein set forth, the building may be rendered, very comfortable, in that the conduction of heat or cold through the walls and ceiling is greatly minimized. The parts of the double channels [9 may readily be formed by well known methods, and when subsequently assembled and secured together, as shown in Figure 9, the channels A and B become unitary structures which will positively prevent the passage of air, whether warm or cold, between the v the spirit of the invention, and that the invention is capable of uses and has advantages not herein specifically described; hence it willbe appreciated that the herein disclosed embodiments are illustrative only, and that my invention is not limited thereto. i

I claim as my invention:

plurality of uprights arranged in spaced relation and having wall plates seated against and secured to the outer faces thereof, wall panels seated against the inner faces of the uprights, channels fitting over the edges of said panels, and a plurality of clips for securing the panels to the uprights, each clip comprising a body portion of angular cross-section having 9. depending 1.
