Patented June 9, 1953 UNITED STATES PATENT OFFICE COUPLING MEANS AND TRIM FOR LAIVIINATED BUILDING UNITS- 2 Claims.

This invention relates to building construction and more particularly to coupling means and trim for panel sections of buildings at corners or where they are angularly related one to an other.

The invention is particularly well adapted for use in building construction, such as is shown in my copending application filed February 24, 1950, Serial Number 146,010, and for use with laminated load bearing and insulating units or panel sections shown in my copending application filed February 24, 1950, Serial No. 146,011.

The principal object of the present invention is to provide coupling means and trim which is inexpensive to manufacture, neat in appearance, easy to install and efficient as-means to retain panel sections in angular relationship without the use of corner posts or studs.

Other objects and advantages will appear in the following detailed description of a highly satisfactory embodiment of the invention, taken in connection with the accompanying drawings, forming a part of this specification, and in which drawings:

Fig. 1 is a fragmentary perspective View looking toward the outside of a corner of a building foundation and wall, showing my invention in use.

Fig. 2 is a detailed horizontal sectional view on the line 2--2 of Fig. 1.

Figs. 3, 4 and 5 are perspective views of portions of the coupling means and trim, parts being broken away and removed to condense the views.

In the drawing I have disclosed the invention as applied to a corner of a building and more particularly an external corner, however, it is to be understood that it is applicable to internal corners, and to roof construction at the ridge of a gable roof.

Mounted upon a foundation 8 are plates or sills 9 supporting panel sections In in angular relation to one another. The coupling means and trim for the panel sections is designated generally by the character I l In the preferred embodiment of my invention, each panel section preferably comprises outer facing sheet I2, an inner facing sheet M and an intermediate corrugated sheet [5 of the character disclosed in the aforesaid application Serial No. 146,011. As there disclosed, the corrugated sheet is preferably shaped so that ridges thereof have straight crown portions l1 secured to the facing sheets, diagonal straight side portions 18, extending diagonally between the facing sheets,

and curved or arcuate side portions I9 joining the portions 18 and I1 whereby the corrugated sheet acts as a strut-like unit, resisting compressive forces acting upon the facing sheets. The straight side portions [8 preferably lie in planes at angles of to the planes of the facing sheets, thus enabling a wkorkman to cut a bevel at the end of each panel section, in a plane closely adjacent to and substantially paralleling the plane of one of the straight side portions [9, so that two of the panels may be disposed with the beveled faces in confronting relation at a corner of the building and with the panel sections in angular relation one to another, as shown in Figs. 1 and 2, where the various portions of the intermediate sheet effectively act as a strut to resist compressive forces acting in planes substantially paralleling a plane bisecting the angle between the planes of the panel sections Ill.

The coupling means and trim ll comprise a first orouter coupling member 2|, a second or inner coupling member 22, and means 23 for drawing the members 2| and 22 toward each other and retaining them in clamping relationship to the panel sections 10. A trim strip 25 for cooperation with the second or inner coupling member 22 and for concealing parts of means 23, and means 26 for detachably securing the trim strip 25 to the coupling member 22, may be provided, but is not claimed in this particular application.

The coupling member 2| may be made from a strip of rolled or cast metal stock of angular cross section or from sheet metal rolled to angular cross section having the flanges 28 to be disposed in planes paralleling the planes of the angularly related panel sections [0 for bearing relationship with the outer faces of the outer facing sheets [2 thereof. If desired any suitable insulating material, such as asbestos paper or plastic, not shown in the drawing, may be interposed between the flanges 28 and the panel sections. In the example shown the coupling member 2! is provided with a plurality of screw threaded shanks 29 forming a part of means 23. These shanks are integral with the coupling member 2 I and are in spaced apart relation longitudinally of the strip in a plane bisecting the angle between the planes of the flanges 28 and normal to the vertex between the said flanges,

3 30 and a web 3| joining the flanges 30. These flanges 30 are in planes paralleling the planes of the panel sections and in bearing relationship with the outer faces of the inner facing sheets I4. Here, also, any suitable material, not shown in the drawing may be interposed between the flanges and facing sheets I4. The web 3| is provided with a plurality of openings 32 in spaced apart relation longitudinally of the coupling member, throu'gh'which the shanks 29 project when the coupling means is being assembled.

The means 23 for drawing the coupling members 2| and 22 toward each other and-retaining them in clamping relationship to the-panel sections 10, in addition to the screw threaded shanks 29 may include nuts 33 secured on the shanks and bearing against the web 3 I.

With reference to the trim strip 25 it is preferably made of some suitable material suchas stainless steel or solidified plastic and of concave-convex cross section. The longitudinal edges are preferably beveled to provide faces 34 for surface to surface contact with the exposed faces of the facing sheets I 4- as shown in Fig. 2. In use the convex'face 35 of strip 25 confronts and conceals the means 23. This trim-strip provides a neat internal corner construction, free-of recesses or cracks and hence will not harbor dirt or other objectionable matter.

The means 26 for detachably securing the trim strip 25 to the coupling member 22 may comprise a plurality of companion clips and 31!, of resih ient material, carried'by the flanges 39 and the trim strip 25, respectively. 1 The clips 36 each have obtuse angularly related arms 3'! and 38, the arms 31' of these clipstil being welded. or otherwise secured to the edges of'flanges 39 and the arms 38' extending toward the web 3| but spaced from the faces of the'flanges 39. The clips 3": are likewise each of a similar shape having obtuse angularly related arms 40' and 4l,.the arms 49 of these clips 3'! being welded-or otherwise secured to-the convex face 35' of strip 25', and the arms 4| projecting toward'the longitudinal edges of the strip but spaced'from the'convex'iace 35. The spacing of'the sets of clips is such that the trim strip may be snapped into place, after the nuts 33 have been turned tight.

"By making the screw threaded shanks. 29 integral with the coupling member 2 l, the workman may more readily locate the position for boring any necessarynotches or holes in the panel sections, for the reception of the shanks 39' by positioning the coupling member near the angularly related. panel sections with the free ends of the screw threaded shanks abutting the corner edges of the panels and marking the places where notches or holes are to occur.

The action of tightening the. nuts 33exerts pressure by coupling sections 2| and ZZupon the outside surfaces of the panel sections in a clamping action and at the same time tends to pull the twopanel sections toward the apex of the angle of panel sections 2| and 22. Ihe net effects are toprovide continuity of external surface and-to rigidly hold the two panel sections to each other. When pressure is transmitted to the corrugated sheet ill, in the example shown, the particular side portions of the ridges thereof which are nearest the edges of the panel sections it, tend to pinch against the shanks 29 and thereby resist collapsing of the panel sections due to the clamping action of the coupling members 2| and 22, the

adjacent portions

18 and 19 of the corrugated sheet 15, acting effectively as a strut.

If desired the voids between the ribs of the corrugated sheet I5 and the facing sheets I2 and I4 may be filled with insulating material 42, a suitable example being shown in the aforesaid application Serial No. 146,011.

I claim:

1. In building construction, 'the combination with two laminated panel sections in angular relation to one another, said panel sections each including spaced apart facing sheets and an intermediate corrugated sheet, the crowns of the ridges of which are secured to said facing sheets and the side portions of the ridges of which extend diagonally between the facing sheets, the
