13 claims.

The invention relates to a building unit for use in constructing walls and has reference more particularly to a building unit of metal that can be mechanically bonded to other units to form walls of dwelling houses and the like and to which can be applied any kind of a surface such as stone, brick or stucco.

An object of the invention is to provide a metal building unit for constructing walls of dwelling houses and other buildings that can be manufactured in quantities to greatly facilitate the construction of said buildings and to reduce their cost, and which will provide for contrast and distinctiveness in their general appearance with simplicity in design.

A further object is to provide a building unit of novel construction having a shape to withstand the maximum load for the thickness of metal in the unit, which can be laid one on the other to form courses in which the joints will be staggered as in regular coursed masonry, and the ribs or load bearing studs will be in vertical alignment, and which will use simple fastening and anchoring means to allow speed in erection with corresponding reduction in labor costs.

A further object is to provide a metal building unit for constructing walls, which will have specially formed members for taking the load, wherein provision is made for lining the inside of the unit with insulation. and which will provide ample air space between the insulated linings.

Another object of the invention is to provide a building unit embodying the novel features of the invention and especially designed for corner construction to bond one course of building units to another course disposed at right angles thereout in the speclfication.\ drawings and claims apl pended hereto.

In the drawings which illustrate an embodiment of the invention and wherein like reference 'characters are used to designate like parts- Figure 1 is a perspective view of a corner section o'f wall partly surfaced with a stucco finish and which embodies the building unitV and conj structional features of the invention;

Figure 2 is a perspective view of the buildingl unit showing the inter-locking end members and apertured sides for receiving plaster or the like:

Figure 3 is a vertical sectional view taken transversely of the unit substantially on line 3-3 of Figure 2;

Figure 4 is a longitudinal vertical sectional view taken substantially through the center of the unit and showing several units in connected re- 5 lation;

Figure 5 is a plan View of a unit showing the dove-tail shape of the end members and other locking means; and

Figure 6 is a perspective view of a corner build- 10 ing unit showing the interlocking end and side members.

The building unit l0 selected for illustration in the drawings, Figure 2, comprises end walls Il, l2, side walls i 3, Il, and a partition I5 extending 15 transversely of the unit and substantially parallel with-the end walls. The `unit is preferably formed from a single piece of sheet metal, by various bending and punching operations although welding or riveting of some of the parts 20 to the main body is within the scope of the invention. As shown in Figure 5, one end of the sheet metal is provided with a hook I6 disposed at an angle to the walls ll and I4, whereas, the other end of the length of sheet metal forming 25 the unit is bent to provide a flange I1 which ts within the hook I6 to interlock the ends. For strengthening the corners of the unit the metal is bent back on itself, forming the 'ribs I8 which are disposed at an angle to the connecting walls.

The end walls Il and I2 of the unit are provided with a vertical projection 20 and a vertical projection forming a recess 2|, respectively, of dove-tall shape, which form interlocking means for joining the unit with adjacent units in end to end relation. As will be apparent from the drawings, the inside dimensions of the recess 2| are slightly larger than the outside dimensions of the projection 20 in orderl that the projection of one unit will tlt Within the recess of the other. The partition is formed yfrom the metal of the side wall i3 which is bent back on itself to form a wall having a thickness equal to twice thatfof the sheet metal yforming the unit. One thickness .or side of the partition is used to, strengthen the unit, being formed to provide a vertically extend# ing vdove--tailed shaped projection` 22`which func# tions as a 'column when the units are laid in y courses in the construction of a wall. Thisjis also true of the interlocking projection 20 and 60 recess 2| so that the formations given the' end@` walls and" lartition provide strengthening col-1' umns -andan interlock for the units. I

The side waus lay 'and u are provided with apertures orlouvers123, Figure 3, iormingthe4 metal prongs 24, which comprise the metal punched from the side walls. These prongs are given a characteristic bend in order that the side walls of the unit will effectively retain surfacing material such as plaster, stucco and the like. It is within the aims of the present invention that the wall constructed of the building units may have a plastered interior and exterior such as stucco or surfaced to represent stonework, brick or cement stone. The openings in the side walls in combination with the projecting prongs provide a surface which will retain wall covering as described just as well as a lath surface,

, a surface formed by expanded metal lath, or a surface provided by terra cotta or other well .known building block. To align the building units when placed one on the other, the upper edges oi' the side walls are provided with inwardly directed fianges 25 having the guide flanges 2 6. The base of the side walls are provided with inwardly directed flanges 21 which have an opening transversely of the unit to receive the guide flanges 26. The base of one unit therefore interfits with the top of the under unit and is prevented from side movement by the structure described.

In addition to the structure for associating the units in alignment one on the other to form courses, the invention provides means for securely fastening the units in this relation. As shown in Figure 5, the flanges 30 extending inwardly from the end walls and partition are provided with guide sleeves 3|, which receive the interlocking members 32 by means of the extensions 33 of reduced width. The members therefore have movement within the guide sleeves 3| longitudinally of the unit from a position inwardly thereof to an interlocking position outwardly towards the end walls and partition, where the members engage with flanges 3l, Figure l2, extending inwardly i'rom the upper edge of the end wall II, the respective sides of the partition and inwardly from the wall of the recess 2|. When the locking members are in retracted position the units are laid one on the other and aligned by locating the guide flanges 26 within the opening between the base flanges 21. This willbrlng the interlocking members in association with the inwardly projecting flanges 3l and movement of the interlocking members in a direction toward said flanges will result in securing the units together. The position the parts assume when the units oi' two courses are interlocked is shown in Figure 4.

The building unit of the invention also provides an air space within the interior of the structure which is insulated from Lthe side walls by the blocks of insulation 35. These blocks extend the height of the unit and from the partition to the end walls, being held in place ,by flanges 30 punched from the partition i5 and end wall |I, and by the projections 2| and 22, respectively.

For bonding the building units of the various courses with those in courses disposed at right angles theretovto form the corner of the structure the invention provides a special unit as shown in Figure 6. The same for half of its length'is identical in construction with the unit above described and shown in perspective in Figure 2. This section has the vertical dove-tail shaped projection formed on the end wall thereof and the projection 22 of similar shape located adjacent the cen-ter partition. The second half of the corner building unit, however, is modified to the extent of making the end wall and it is proposed to provide the end wall |2 with 5 louvers 23 so that it will be understood that the corner building unit has all those features described with respect to the unit of Figure 2. The location of a corner unit in a wall construction is clearly shown in the perspective view of Figure 1. 10

To illustrate an application of the invented units in the construction of a Wall the drawings show in Figure 1 a corner wall structure mounted on foundation 31. The rst course of building units are fastened to a bed plate or sill 38 which 15 is anchored to the foundation by bolts 39. The bed plate is provided with a plurality of spaced openings 40 having a length in a direction longitudinally of the bed plate equal to the space between inwardly directed flanges 34 of the unit. 20 The ledge provided by these openings receives the interlocking members to fasten the first layer of units to the foundation. On top of this course is laid a second course which is fastened to the base by the interlocking members de- 25 scribed with the units in both courses being joined in end to end relation by the interlocking forma'- tions on the end walls. The operation of laying the building tile continues until a wall of desired height is secured. It will be noted that the resulting structure has the columns formed by the dove-tailed projections 20, 2| and 22 in vertical alignment and that the joints in any particular course are staggered with relation to the joints in an adjacent course; ,The exterior of the resulting wall is shown partly covered with stucco 4| although it is to be understood'that the metal exterior may be finished to simulate stonework, brick or the like. v

It is to beunderstood that I do `not wish to be limited by the, exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
