WALL cons Applicationv filed ,June 13,

The present invention relatesto the vconstruction of walls and partitions, particu-l larly with building slabs of: the character disclosed in our Patents -:,.'7':1,4Ob,989 and #1,410,932. y y

Some of the more important objects of the invention are to facilitate theV setting up of the slabs and insure their proper alinement in the wall, and to provide a secure anchorage for the ends ofthe slabs, which can be used to meet various building requirements.

In. the accomplishment ofthe foregoing and other objects we have devised a chank nel construction for holding the ends of the slabs, embodying certain novel features and-combinations of parts, as will be clear fromthe following specification. v

lIn the drawings accompanying and forming part of this specification therey are il- Vlustrated certain preferred embodiments of the inventiomwhereof Figure 1 is a broken plan View, illustrating a method of blanking out the channels from sheet metal plates or strips.

Figure 2 is a broken plan showing asection of one of the channels blanked out and detached from the contiguous channel blanks.

Figure 3 isa broken of the formed up channel. y y

Figure 4 is a part sectional broken'viewv of a wall constructed of the patented slabs ersoective view P 1 and having incorporated therein, features of the present inventionf 'n Figures 5 -and 6 are broken sectional views illustrating the application of the channel to av wooden beam and to a structural l-beam' 1 respectively. 1

F'gure'T is a broken detail of ya channel such as used over the top of a doororwindow frame, and Figure v8 is a further detail of a channel of this type. y Y

The channel structure comprises a back 10 having angularly extending side flanges 11 which, as shown in Figures 3, 4 and 5, are spaced to receive between them the edges of the reinforced building slabs :12. These fianges are discontinuous or interrupted by` cuts 13 so that they` may be' bent into posif tion, one or more sections at a time, and the lines on which the flanges are bent may be defined by rows of perforations or by 'scorv ing or creasing asindicated at 14. o The side flanges of the channels are per-l forated for the passage .of cement or bond- TRUCTION;

ingy material and for the passage of'suitable fastenings which may be employedwhen rerations 16 are indicated as of circular' shape."

lTo provide the interruptions in the'flanges and at the same time furnish means forV fastening the channels in place, the material of the flanges may 1'? whichfmay be sides of the channel, as in Figures 3, 4 and 7 or be bent backward intoengagement with a supporting structure as in Figures 5 and These attaching tongues usually areper-A foi-ated as indicated at 18 orother suitable fastenings.

The channels may be constructed ure 2 I have shown Yhow they may bef cut from a single'sheet without channel strips, this providing at once the be cut` to form tongues left outstanding at the vto receive nails Y ofaIV` --fairly heavy gage sheet met-al and inv Figwaste metal, `this View indicating how'the extending interruptions in the flanges andthe pro- 'y jectin'g tongues forv the anchorage 0f the channels, which tongues havetheirflength increased tothe extent of the width of the flanges;

Preferably the backsof the channel stripsy are slotted at spaced'intervals on longitudinal and transverse'lines, as indicated at 19 and 20, so that where possible securing fastenings lmay bedriven directly through the back into a supporting beam, flooror Y other structure, said slots y allowing' for a certain amount of adJustmen't may be necessaryor desirable.

In yconstructing a wall from slabs like channelsV on the floor and another channel in line therewith on the ceiling or overhead mit the Vchannels may be vsecured with the 4 anchorage tongues or straps in outstanding flat relation, as with the floor channel at `where lthat those shownin the patents referred to,' the'y preferred practice is to secure one Yof the V t0 hold the If conditions perstructure. The. centrallyf disposed perfora Y tions or slots in the back of the channels ma? terially aid in placing theV channelsbecauseA with these it is simply'necessary.v to draw line where the center of the partition 'is to 'be the right in Figure 4. Under other circumstances the supporting straps may be bent backward and nailed directly to a wooden' supporting beam 2l, asin Figure 5, or be bent over the lianges of an I-beain 22 after the manner of attaching clips as shown at 23 in Figure 6.

As shown in Figure 4, the channels may be employed for securing the slabs in position about a door or `window :trarne and for like purposes. W'here a channel is used over a door or window frame for holding in` position the lower ends of the short length slabs 24.-, the back of the channel may be cut to a. length equal to the top of the door trainees indicated at Q5, and the side flanges be extended beyond this point as 26, so as to embrace the `opposite faces of the adjoining full length slabs. This, it Will be seen, braces both the short slabs and the frame and serves tobind these parts together. p

VTo facilitate the building up of the slabs into a wall structure the channels may be secured in place with the flanges at one side only bent up. into position, as at the right inV Figure 5.V These angularly turned flanges then serve as stops for the slabs and theopposite open sides ofthe channels enable the slabs to be readily slipped into position back against such stops, after which tbe-fianges at the open side can be bent over, section by section, to vsecure the slabs in position.` The bending` in of these flanges also operates to force the slabs into aline- Inent and to hold them locked firmly in place. The openings in theside llanges enable the'iormation of bonding keys between the slabs, the channels and the structural `units with which the slabs are associated.

It will be seen from the :foregoing that this invention makes it possible to construct a wall of slabs or other building units practically as fast as the units can be Vput together. Furthermore, the wall thus constructed is securely anchored and braced. The structural channels which make possible the attainment of these results can be produced inexpensively from stock grades of sheet metal and can be readily bent andy cut to meet particular requirements.

As an alternative to the slightly modified form of channel shown in Figure 7 for use over the door Vand window frames, a piece of the channel may be cut as in Figure 8 to answer the saine purpose. As shown in the latter view referred to, a longitudinal cut 30 is made in the back extending inward to a transverse cut 31 and the two sections 32 of the back thus partially severed from the back are then bent out into the plane of the side flanges so as to constitute, with the side flanges, extensions which will pass toiopposite sides of the adjoining slab and thus binding the slabs and frame together in the same manner as with the construction in Figure 7.

What, we claim is:

l. A structural channel comprising a back and side flanges the'back having centrally arranged slots therein and the side flanges having bonding perforations and attaching tongues cut from the material of the side flanges and projecting from the back at an angle to said flanges.

2. In a wall structure, the combination with wall slabs of different lengths, ot' a channel having ay back engaged over the ends of the shorter slabs and side flanges extending over the end edges of the shorter slabs and projecting beyond the saine over the opposite faces of the adjoining longer slabs.

3. In building construction, 'wall slabs standing in adjoining edge to edge relation, a positioning and supporting channel for said slabs having a back with an. angularly extending side flange at one edge providing a stop for the slabs and separately bendable flange sections at the opposite edge for securing the slabs positioned against said stop and attaching clips for the channel partially severed from the material of the side flanges and bendable into different securing `positions.

4. A combinationas in claim 3 in which the side flanges have bonding perforations and in which` the removed supporting clips 'from the side flanges provide bonding openings for the entry of bonding material into the channel and between the adjoining edges of the slabs. i Y l In a wall structure, the combination with wall slabs of different lengths, of', aV channel having a back engaged over the ends of the shorter slabsr and a side flange extending over the end edge of a shorter slab and projecting beyond the same over the face of an adjoining longer slab.

In witness whereof, we have hereunto set our hands this 11th day of June, 1923.
