Claims.

The invention relates to building constructions ing one part in the assembly of several of the and more especially to pressed steel structural framing and method of joining the same.

-The primary object of the invention is the provision of a construction of this character,

wherein the said metal framing members are of hollow formation and are precut at the factory so that the same may be assembled at the place of erection of the building or the like without requiring labor in the cutting of said membersfor proper assembly thereof, these members being interlocked at the point of use thereof'in a novel manner and are composed of a plurality of units adapted for interfltting with each other.

Another object of the invention is; the provision of a construction of this character, wherein the units of .the framing members are assembled and locked together in a novel manner without the use of nails or the like and create a rigid unitary formation, being precut as per plans of a structure so that the work or the labor re quired in thefleld would merely be assembly.

A further object of the invention is the pro-.

vision of a construction of this character, wherein lathing, wall facings, sheathing material may be readily and easily fastened to the framing without the use of nails or other like fasteners and the framing being devoid of wood thus being of fireproof characteristic.

A still further object of the invention is th provision of aconstruction of this character, wherein the framing is of hollow sheet metal formation and in the assembly thereof for the erection of an edifice will he possessed of maximum strength and durability, being susceptible of reinforcement through the use of cementitious or homogeneous material.

Astill further object of the invention is the pro ision of a construction of this character, wherein evolves a novel method of the joining of the units in their assembly to expedite erection of an edifice possessed of maximum strength and longevity.

with these and other objects in view, the invention consists in the features of construction,

combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention and pointed out in the claims hereunto-appended.

Referring to the drawings in detail, particularly Figures 1 to 5 inclusive, each framing member constituting the present invention comprises pairs of web and flange units It! and H, respectively, each made of pressed steel and of hollow formation, -being precut for .mere assembly work in the field after shipment or distribution from the manufacturer. The units l0, each has the reversely beveled outer areas or portions l2 at one side thereof and an intermediate countersunk outwardly bulged area or portion 13, respectively, so that when these sides match with each other with the areas or portions 13 making medial contact with each other, there will be presented therebetween substantially arrowhead-like gaps or seats I A opening outwardly transversely with respect td-the units In and approach the intermediate areas or portions I3 of. said units.

The flange units II at the inner sides I5 thereof,'each has medially of its inner side I 5 and longitudinally thereof a countersunk arrowhead shaped coupling rib l6 while created at opposite sides thereof are the channels or grooves ll,

these being adapted to accommodate the longer opposite edges of the units In with the ribs fitting the gaps or seats I4 between said units III in the assembly of the framing with the result that these units will be interlocked with each other to efiect a substantial eye stud, joist, beam or other supporting member denoted generally at A. i

To effect a three-way stud construction B, the assembly thereof is had by arranging a group of three eye studs, beams, joists or other supporting members-A as shown in Figure 3 of the drawings and connecting these by hollow substantially triangular shaped connector strips or forms I8 which are welded or otherwise made fast to confronting sides III. of the units next thereto and at right angles to each other when a pair of the members A are arranged in spaced parallelism with each other and another of these members intermediate with respect to the latter and disposed crosswise in its lay thereto.

To efiect a double eye" beam, stud, joist or other supporting member C, a unit 2| of hollow formation having the contracted intermediate portion 22 and the outer portions 23, respectively,'

is created, these being in association with the units 24 and the units 25, respectively. The

units

24 and 25 are similar to the units In and II and the assembly of these with the unit 2| being shown in Figure 4 of the drawings.

To effect the creation of a corner structure -D, a series of members involving the

units

26 and 21, respectively, are employed, these being similar to the units I0 and I I and their assembly,-

and are connected together by the strips or

forms

28 and 23, respectively, these being welded or otherwise made fast in the joinder thereof with the units 21 next thereto as is clearly shown in I Figure 5 of the drawings.

In Figure 6 of the drawings there is shown a portion of a door jamb 3U fitted in a. framing E involving a pair of sheet metal hollow units 3I formed with jaw extensions 32 and the arrowhead shaped locking ribs 33, respectively, the jaws being engageable with the unit 34 while the ribs- 33 interlock with the latter and a hollow retaining strip 35, respectively, which conceals between it and the unit 34 a filler strip 36 having welded or otherwise made fast thereto, bolt-receiving nuts 31 for fastening bolts 33 securing the strip in place, a-portion of the door being indicated at 39 fitting the jamb 3II.

In Figures 7 and 8 of thedrawings there is shown a window sash or frame assembly F involving the units 40 and 4I,-. respectively, these being similar to the

units

33 and 34, the retaining strip being indicated at 42 in the window frame at 43, respectively, this having a packing strip 44 associated therewith, the filler stri 45 being fastened at 46 and the strip 42 fastened at 41, respectively.

In Figure 9 01 the drawings there is shownvertical and horizontal supports'as employed in building construction and each support involves the member A including the units I0 and I I, these interlocked with each other for the eye beam, joist orthe like formation, a portion of the vertical support being indicated at 48 while a portion of the horizontal supportis indicated at 49. About the support 4l is a cap member in the form of a sleeve'having the instruck portions 5| so that the cap in its formation will snugly embrace the support 43. The instmck portions SI carry lips 32 interfitting the horizontal support 43 while at opposite ends of the cap 50 are bendable wings 53 which are disposed by bending in overlapped relation to the horizontal support 49 and both the said ends of the cap 50 and the cars 53, respectively, each has a clearance for accommodating a wedge-shaped locking key or fastener 54, it having burrs or latching nibs and 56, respectively, for the retention of the fastener 54 in place. The supports 43 and 43, each carries preformed slot formations 51 therein, these being initially partly cut into the units I 0 and I I so that they can subsequently be cleared for accommodating the keys or fasteners 54 for the joining of the

supp ts

48 and 49 together.

The units I0 and II, after assembly thereof witheach other, can be. reinforced by fillings of cementitious material, the hollow formations of such units being receptive of such material.

With reference to Figure 6 of the drawings, the lamb 30 is susceptible of reversal for the setting thereof with respect to the door 33 should it swing outwardly or inwardly in the hanging of such door.

It ispreferable that the, filler strip as be ms- 1 site ends and in the use of such cap are bent from this position to overlapping joining part.

The keys or fasteners 54 can be used; for attaching to the framing metal .lathing, wall or ceiling facings and sheathing or the like, these relation to an adkeys or fasteners 54 being bendable'into clinching or gripping engagement with the latter at theirends exposed and projected beyond the frame.

In the use of .the invention in its novel sectional construction, it is customary to apply a mastic of low heat conductivity in the nature of a thin film between its sections and in this fashion lessen the concentration of moisture and thus add to the usefulness of the invention. This mastic of low heat conductivity is located between the contacting surfaces of the web and flange section wherever necessary.

It is further understood that the web and flange section when set up for use as an I-beam will function as such at any required locality in structural framing and thus offer a solution for insulation and to feed direct transmission of heat as occurs in the use of steel framing of modern trend in building construction. This sectional hollow assembly hereinbefore set forth eliminates or prevents warping particularly where there is great difierences in the temperatures particularly with regard to opposing flanges and a silent movement characteristic is allowed'with respect to component parts through the elasticity of the mastic film when employed at contacting points of the structure. It is, of course, recognized that cold and heat effects. expansion and contraction of composite parts of steel or metal resulting in perceptible noises and groans where the movement of one part over another takes place, this being produced through mechanical friction and by the presence of the'mastic film between adjacent or at contacting points of the parts the mechanical friction or movement of these parts is silenced.
