Filed Feb. 8; 1933 INVENTOR- Patented n... 29, 1936 PATENT OFFICE BUILDING WALL STRUCTURE Mills G. Clark, Cleveland Heights, Ohio, asslgnor to Insulated Steel Construction Company, Cleveland, Ohio, a corporation oi Ohio Application February 8, 1933, Serial No. 655,790

Claims.

This invention relates to wall construction in metal building structures. The general objects oi the invention are to provide a highly efficient wall construction of simple form, low cost 5 and convenient erection; and to these ends, one

. wherein a large and more diilicult part of the assembly may be made in the shop, leaving for the fieldwork, principally only the securement together of the remaining parts.

The exact nature of this invention, together with iurther objects and advantages thereof will be apparent irom the following description taken in connection with the accompanying drawing, which shows perspective views illustrating the invention, and in which Fig. l is a detail of one oi the typical units from which the wall base is made up; Figs. 2 and 3 show wall base sections, as formed in the shop; Fig. 4 illustrates the manner oi joining a pair of such sections in the field; Fig, 5 illustrates the completed wall base; Figs. 6-8 illustrate corner constructions.

With reference now to Fig. l the unit comprises a sheet metal strip bent lengthwise along parallel lines to form a pair of wide shallow adjacent panels opening oppositely, with the channel bottom parts I defining side faces for the unit, and lips 2 extending" from the free channel extremities at the opposite edges of the unit. The. channels have flat sides 3 and'the bottoms I are also flat, and the parts are generally rectangularly disposed, but the sides 3 preferably have suillcient pitch to permit stacking of a plurality oi similar units in nested relation. Such pitch is shown in Fig. 1 oi the drawing, but in Ellie remaining figures, ior simplicity, no pitch is own. More channels than the pair illustrated could be provided per unit, but I have found a pair preierable for commercial reasons'and for convenient handling. A unit may be made from 20-gauge stock 22 inches wide with each channel 8 inches wide and 2 inches deep, leaving the lips I a width of about inch. Obviously from wider stock more channels oi similar dimensions could be obtained per unit, but not as cheaply p channel. From a number of such units, wall base sections are made upas illustrated, Fig. 2, the units being disposed in interlocking relation, in a com 0 mon general plane, the channel bottom parts delining side iaces ior the section, the parts 3 iorming webs between these faces and the end.

channel sides Soi each unit being hooked over the c part oi the next unit, and the imated, where metal oi the light gauge specified be employed, with all oi the webs I having the 10 same dimension. It will be appreciated that in the drawing the thickness oi the metal is exaggerated.

The sections are thus made integral, and are 1 1 generally .of continuous repeated S-section. 5 Their length will depend upon the building in which they are to be used, and they may be as long as the height oi a two-story dwelling without being toocumbersome or heavy to be handled in erection. 2o

t In the field, the sections are erected and assembled as illustrated in Fig. 4. Their adjacent end parts are in hooked relation as before but the sections are adjusted in their general plane to give the desired overall length, which usually 25 in practice leaves an overlap 5. At the overlap, the lips 2 are secured to their underlying parts by self-threading screws 6 driven by hand. The metal of the units is sufllciently thin to permit this, the screws 6 being driven as necessary, 30 making their own perforations in the metal, cut-' ting their own threads as they proceed and holding in the threads against withdrawal. The eiiect oi' the overlap oi thesections is to provide therebetween, as at 5, a hollow rectangular 35 column in the plane of the wall, running vertically, and adding great. rigidity and supporting strength to the wall.

Aiter the wall base is thuseompleted, the metal is overlaid with boards I' of stiff composition of 40 heat insulating'properties. Many such boards,

' making use oi fibrous by-products, are to be being driven into the near bottom part I oi one oi the channels oi the metal base, the screw cutting and threading its own hole when driven as a nail.

Although the wall board may have little unit strength, yet when the metal baseis covered on bothsidesas-inrlg.5,muchstrengthisaddedssto the whole since the board amply maintains the webs 3 against buckling. Also, the addition of the board results in a wall base highly resistant to heat transfer. And particularly if the wall board be of fire resistant properties, the metal is protected, and the wall base thus has highly desirable qualities from every point of view.

Where adjacentwall panels are disposed to form corners, it will be found that the adjacent end parts of the panels always define a vertically extending, externally opening recess generally of rectangular section as indicated, Figs. 6, 7 and 8, which illustrate all of the possible relations of the parts at typical exterior corners. A hollow metal column 9 of square section is disposed in the corner recess and the metal parts secured to the column and thus to each other, preferably as by welding. The column being preferably of seamless steel tubing or the like, its presence adds great strength and rigidity to the metal work. When the insulatingboard I is attached it is overlaid upon the column both concealing and protecting the latter,'

as indicated in Fig. 6.

After the wall structure has been coveredwith insulating-board, suitable'finishing means may be applied, such as plaster or paint on the inside surfaces, and metal or masonry sheathing on the outside surfaces, all as will be understood by one familiar with the art.

What I claim is:

1. A metal building wall base section comprising a plurality of similarunits, each unit comprising a sheet metal strip bent lengthwise to form wide shallow adjacent channels opening oppositely,'with the channel bottom parts defining side faces for the unit, and with lips outwardly extending from the free channel extremities at the opposite edges of the unit, said units being disposed edge to edge in a common general plane, with the lip of one unit overlying the bottom part of the near channel of the next unit, and secured thereto as by welding, whereby the section comprises in effect a continuous repetition of said units, and the side edge parts of the section are those of the end units.

2. A metal building wall base section comprising a plurality of similar units, each unit comprising a sheet metal strip bentlengthwise "to form a pair of wide shallow adjacent channels opening oppositely, with the channel bottom parts defining side faces for the unit, and with lips outwardly extending from the free channel extremities at the opposite edges of the unit, said units being similarly disposed, edge to edge in a common general plane, with the lip of one unit overlying the bottom part of the near channel of the next unit and secured thereto as by welding.

3. A metal building wall base including an adjacent pair of sections each composed of similar units, each unit comprising a sheet metal strip bent lengthwise to form wide shallow' adjacent channels opening oppositely, with the channel bottom parts defining side faces for the unit, and

with lips outwardly extending from the free channel extremities at the opposite edges of the unit, said sections being disposed in a common general plane, with the end lip of one section overlying the bottom part of the near channelpf the next section, substantially spaced from both sides of said near channel, and secured to said bottom part of the latter, whereby the adjacent end parts ofsaid sections overlap to form a hollow rectangular column running with the bends of the parts, and located intermediate the ends of said base.

4. A metal building wall base including an adjacent pair of sections each composed of similar units, each unit comprising a sheet metal strip bent lengthwise to form wide shallowadjacent channels opening oppositely, with the channel bottom parts defining side faces for the unit,

grally joined units, are adapted to be made up in the shop with welded connections, and joined in the field by threaded connections.

5. In a metal building structure having wall panels comprising sheet metal strips bent lengthwise to form wide shallow adjacent channels opening oppositely, with lips outwardly extending from' the free channel extremities at the opposite edges of the units thus formed, a corner construction for an angularly related pair of said panels, comprising a hollow metal column of quadrilateral section seating in the external recess formed by said disposition of the panels and secured to the abutting panel parts.
