FRAZIER, OF DETROIT, MICHIGAN, ASSIGNORS PRODUCTS COMPANY, OF DETROIT, MICHIGAN, A CORPORATION WALL GROUND WORK STRIP Application filed January 13, 1930. Serial No. 420,576.

This invention relates generally to improvements in building construction and more particularly to the provision of means f r securing wall ground work such as wall board and the like in place.

One of the principal objects of this invention is to provide means of the above type in the form of a strip which, in addition to securing the wall ground work in place, also functions to. separate adjacent sections of the ground work forming the wall and further operates to interlock the plastic material applied to the ground work with the strips to form a homogeneous mass.

A further advantageous feature of the j the wall ground work in angular relation to each other to present invention resides in the provision of an anchor strlpcapable of being readlly deformed for securlng the varlous sectlons of form a corner assembly. Astillfurther object of this invention is to provide a strip of the above character which may be readily formed by a stamping or rolling operation and, as a consequence, lends itself to economical manufacture and also one :which may be expediently secured to its sup port irrespective of slight surface variations of the latter.

vWiththe foregoing'as well as other objects manner in which the in view, the invention resides in the novel construction ofv the strip and the manner in which it cooperates with the wall assembly to form a homogeneous mass.

In'the drawings: Figure 1 is a fragmentary perspective view illustrating one application of our improved anchorstrip. f I 1 .Figure '2 is a sectional view showing the strip is secured to the Stud, members. I

' Figure 3 is a cross-sectional view'through the strip showing the. wall ground work in position. I

Figure 4 is a plan view of a strip of metal illustrating the manner in whichthe strip is formed. v Figure 5 is a sectional view showing the ap plication of the strip to aninner corner as- Figure 6 is a view similar to Figure 5 showing the application of the strip to an outer corner assembly.

Referring now to the drawings, it will be i":

noted that there is illustrated in Figure 1 an anchor strip 10 having a body portion 11 substantially channel-shaped in cross-section with the leg portions 12 of the channel terminating in oppositely extending foot flanges 13. The foot flanges 13 cooperate with the leg portions 12 to form a rabbeted recess upon opposite sides of the base 14 of the channel for receiving the

adjacent sections

15 and 16 ofthe wall ground work. The construction is such that the adjacent edges of the

sections

15 and 16 abut against the legs 12 of the channel and, as a consequence, tance commensurate with the width of the base 14 of the channel The width of the leg portions 12 preferably corresponds to the width of the

sections

15 and 16 so that the outer surfaces thereof are substantially flush with the outer surface of the base portion 14 and forms in effect a continuation thereof.

In order to secure the

sections

15 and 16 in place upon the strip, the base portion 14 of the latter is provided with a series of longitudinally spaced struck out

tongues

17 and 18 adapted to project alternatively in opposite directions over the adjacent edges of the

sections

15 and 16. As will be apparent from Figure major portions of the tongues are arranged flush with the exterior surface of the base 14 and the end portions thereof are bent upwardly as indicated by the reference charare spaced from each other a dis- '3 of the drawings, the

acter 18' to facilitate engagement of the forms with the stripan interlocking connection; It will also be noted that the plastic material is permitted to flow into the openings formed by striking out the

tongues

17 and 18 so that these openings also serve to interlock the plastic material with the strip.

Thus from the foregoing it will be observed that'the strip, wall ground work and plastic material are rigidly secured together to form a homogeneous mass. The width of the slots are predetermined and are substantially equal to the width of the material therebetween and since it has been stated v above that the notches are substantially f-shaped it will be apparent that the notches 20 and slots 21, in addition to preforming the above described function, also provide means for breaking the strips to the desired lengths.

portions of the legs of the channel from the foot flanges and bending the latter outward- 1y to form a slot of suflicient dimension to permit the portions 24 of the studs to engage between the legs and flanges. In practice, it has been found'that the above construction is suflicient to maintain the strips in assembled relation with the studs without the aid of any-securing means.

Referring now more in detail to Figure 4, it will be noted that the strip 10 is de;

velopedfrom a single sheet of'metal by' first punching the openings 21 therein and striking out the

tongues

17 and 18 and then fashioning the strip to the desiredcontour by a stamping or rolling operation to form the finished strip. In thisconnection it is to be noted that in fashioning the material to form the completed strip, portions of the openings 21 extend-into the leg'portions 12 of the channel 11 forming the openings 19 andz20. I V j In Figure 5 wehave illustrated a strip25 especially designed for inner corner assemblies to secure the sections 26 and 27 of the wall ground work in angular relation to each other. As shown, the strip is provided with flanges 28 and 29 extending at anangle to each other: corresponding to the angular relationshipiof the sections 26 and 27 and adapted to engage the inner angular surfaces 30 and 81, respectively, of the stud member e 32. The flanges 28 and 29 are connected to- 'getherby means of a web 38 having portions E l-cooperating with the flanges 28 and 29' to form rabbeted recessesfor receiving the'sections 26 and 27. The adjacent edges of the sections a-re'adapted toabut againstthe portions 34 of'the web. and are held in place by means oftongues 35; struck'out from the cen .The transformation of the strip 10 to the strip 25 is clearly illustrated in Figure 5 wherein the strip 10 is illustrated in dotted lines. 7

In Figure 6 we have shown a strip 37 especially designed for exterior corner construction. This strip comprises

flanges

38 and 39 adaptcdto engage the exteriorly angular surfaces 40 and '41, respectively, of the stud member 42- with the longitudinal'edges 43 of the flanges adjacent each other. Extending outwardly at substantially

right'angles tothe flanges

38 and 39 are flanges44 and 45, respectively, which form abutments for the adjacent edges of

theground work sections

46 and 47. The flanges 44 and-45 are connected together by means of a web 48 having the struck out tongues 49 adapted toextend over theadjacent edge portions of the

sections

46 and 47 to secure the same in place. In this connection it is to be noted that the formation of the web 48 is substantially the same as the base of the channel 14 0f the strip 7 11 in that it is provided with openings intermediate the tongues49 for the reception of the plastic material. The strip illustrated in Figure 7 is preferably identical in construction tothe strip. 10,

hereinbefore set forth, with the exception that the foot flanges 18 are'provided with extensions 50; The extensions are preferably flared outwardly from the outer edges of the foot'flanges, as illustrated in Figure 7, and

are adapted to engage a suitable support.

Thearrangement is such as to provide a spring base for'the strip so thatany variations in the surface of the support will be compensated for by the re'siliency'of the extensions. The above form of strip finds particular utility for use with steel joists where'- in theflower member often times'varies in level. What we claim as our invention g 1.
