Oct. 23, 1945. G. w. Du LANEY STRUCTURAL WALL SECTION Filed Dec. 28, 1943 Patented Oct. 23, 1945 UNITED STATES PATENT OFFICE 2,387,432 STRUCTURAL WALL SECTION George W. Du Laney, Camden, N. J Application December 28, 1943, Serial No. 515,893

Claims.

My invention relates to structural shapes built up from sheet or strip metal riveted. spot welded or otherwise Joined back to back so as to provide shapes which could not be rolled without using metal of much thicker cross section.

A purpose of the invention is to provide heat insulation along the edge of a section while at the same time finishing the flanges of the section and giving cushion support to the flanges.

A further purpose is to provide a double channel. I-beam or other such construction having a nailing section in line with the web of the section.

A further purpose is to provide a nailing section in line with the web of a composite double channel or I-beam, protecting the nailing section from splitting by a covering about the section which receives the nails.

A further purpose is to surround a nailing section in a composite I-beam or double channel with y heat insulation with or without additional surrounding wrapping to the nailing section.

Further purposes will appear in the specification and in the claims.

I prefer to illustrate a few forms only. selecting forms which are practical. effective and inexpensive. which can be built up with a minimal metal content and which at the same time well illustrate the principles of the invention.

. Figure 1 is a fragmentary section having double channel members back to back showing the flanges at both ends finished, one end with and the other end without heat insulation.

Figure 2 is a .perspective corresponding-to Figure 1 but omitting the finish at one end and inserting a nailing section instead of the heat insulation and finish at the other end.

Figure 3 is a perspective corresponding to Figures 1 and 2 except that it provides nailing sections at both edges.

protect against splitting of Figure 4 is a perspective having the same nish of a heat insulated surface along one edge as Figure 1 and a pair of flanges intended to receive a nailing section at the other edge.

Inthe drawing similar numerals indicate like parts.

In Figure 1 the section of I-beam or double channel construction is built up of sheet or strip metal forming channels l and l, back to back, spot welded together and terminating in oppositely facing channel flanges 'l and 8 upon the channels l and I and III upon the channel I.

Theoppositely facing double channel flanges` l and Ifalong one edge of the I-beam and l. i0 along the other edge of the I-beam are enclosed by re-eni'orcing and finishing inwardly facing channels I I along one edge and i2 along the opposite edge. In each case the facing or finish is turned parallel to the webs at I3 and I4, I5 and Il at the two edges and is then turned toward the webs at I'I, I8 at one end` and at I8, 20 at the other end.

In the finish seen at II, I3. Il, i1 and I8. heat insulating sheet material 2i is wrapped about the flanges 1 and 8 inside the enclosing re-enforcing finish II, I3. I4, Il and I8 while there ls no intervening material between the re-enforcing finish I2, I5, i6, I9 and 20 and the channel flanges.

In Figure 2 the structure is similar to Figure 1 except that the channel flanges 1 and 8 of double channels ii', B are not finished or re-enforced and the channel flanges 8' and i0'4 along the opposite edge of the section are turned awayv from the flanges 8' and Ill' and toward each other to form clamping terminal flanges 22 and 23 so as to receive and retain a nailing strip 24 which may be of wood or of composition adapted] to receive.

the nails.

The nailing strip is sectioned to indicate wood.

In order to protect this nailing strip from splitting, it is wound with tape 25. The edges 26 and 2l of the converging gripping flanges 22 and 23 engage the nailing section and hold it back so as to seat against the channel ends, the faces 28 and 29 of the channel flanges 8' and I0'.

In Figure 3 the construction at what is shown as the upper edge of the section is identical with that at the lower edge of Figure 2 except that this upper nailing section 2l is not taped in Figure 3 and the converging flanges bear at vtheir edges 26 and 21 directly against the strip itself.

The lower edges of the channels 53, E? in Figure 3 are formed at 223 and 233 of the same general shape as the flanges 22 and 23 of Figure 2 and Figure 4. As a result the flanges 22 and 2l' in what appears as the upper edge of Figureg3 and the flanges 22n and 2l in Figure 3 grip or are adapted to grip the insert nailing material :lust as is the case with flanges 22 and 2l of Figure 2.

In Figure 3 the strip of nailing material is not wrapped at the upper edge and is wrapped with heat insulating material 2|' at the lower edge of this view and is taped at 25 to hold the parts together and prevent splitting.

The heat insulating materials in Figure 1 and at the lower part of Figure 3 both perform cushtions and modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art, to obtain all or part ot the benefits of my invention without copying the structure shown, and I, therefore, claim all such in so far as they fall within the reasonable spirit and scope of my claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A pair of channels placed back to back and having the flanges of the channels reversely turned converging along their outer edges at one end to form a socket and a nailing strip extending between the inturned flanges and the channel flanges so'that the terminal edges of the converging ilanges grip the nailing strip and the strip is free from engagement by the converging flanges between the edges and the channel flanges.

2. A pair of channels placed back to back and having the flanges of the channels reversely turned diagonally along their outer edges at one end to form a socket having converging flange walls and a nailing strip extending between the converging flanges so that the terminal edges of the converging flanges grip the nailing strip and the strip isfree from engagement by the converging flanges between the edges and the channel flanges, and a wrapping oi' tape about the nailing strip between it and the edge terminals of the flanges to protect the nailing strip against splitting.

3. A pair of channels placed back to back and having the flanges of the channels reversely turned diagonally, converging along their outer adjacent surfaces at one end to form a socket and a nailing strip extending between the converging flanges so that the terminal edges of the converging flanges grip the nailing strip and the strip ls free from engagement by the converging flanges between the edges and the channel flanges, and heat insulating material between the nailing strip and the terminal edges of the flanges to heat insulate the nailing strip.

4. A pair of channels placed back to back and having at the edges of their channel flanges reversely turned converging clamping flanges between which lies a socket, and a nailing strip between the converging flanges and extending in a direction away from the channel webs beyond the converging flanges, heat-insulating material about the nailing strip and tape about the heatinsulating material, the converging flanges engaging the tape at their outer edges and free from engagement with the tape adjacent their outer edges, whereby the edges hold the strip in or allow it to adjust within the socket.

5. A pair of channels arranged back to back and having at one end channel flanges extending away, from each other and converging terminal anges, forming a socket, and a nailing strip extending outside of the socket, heldin by the edges of converging flanges and the strip is free from engagement. by the converging flanges between the edges and the channel flanges and seats against the faces within the socket of the channel ilanges, whereby the nailing strip is held in by the edges as distinguished from the faces of the converging flanges and can have some motion with respect to the seat at the bottom of the socket.
