Application June 25, 1947, Serial N 0. 756,968

6 Claims. 1

Th e present invention relates to clamps for ement form panels, its objects being substantially the same as specified in my co-pendins application, filed April 4, 1947, Serial No. 739,309, now Patent No. 2,461,733.

;A furtherobject of the present invention is to simplify the construction of a clamp, whereby the panels and the tie may be interlocked and ma ntainedin. a r d mu ual elat ondu ins th .ereetion, of. a. concrete wall.

-A still. furth ri i ct oithe pre e t i v ntion is.- the.:prov s en of a flamncapabl o nga n and interlocking a pa o a ls t at e var usang la positions of the atter th enecttoth panels- Another object of the present invention is the pro i ion, ineor binatio with a lur l of nement form panels having angle members affixed th ret ad acent t r margin l or io wit t es. inte pos d b tween t mar n f adj cen anels a d t ediaeen ne e' emb s, of a uitab clam apable o imu aneousl e a ingthe tie an a ir of th ad ace t a l member .A' u therobieet of th re enti vent on s the pr vision, n. a am of t e e ndi te of;

position recesses 12 will form an oblong slotl3 for extending therethrough tie II. Each of panels it is further provided along its margin with angle member I l, which is aiiixed-by its base to the body of the paneLand the remain ing portion of which forms-a vertical'leg portion. ISaid angle member I l is spaced from the edge of panel H! for providing clearance for re} cess l2, and for accommodating between two angle members is in a pair of cooperating panels 1!! said tie ll. a

The clamp constituting thev subject-matterof this application includes a block or body portion E5 of substantially rectangular formation. Said body portion l5 along one of its narrower ends is provided with a, central recess IG-for. effecting a pair of spaced jaws 17, which remain a mu-.-

tually rigid relation. Each of said jaws I! on its.

inner face and along its free end is provided withbead iii. The two opposed beads in two jaws H are spaced to the extent corresponding to the widthof a pair of vertical leg portions of said angle member M, with tie ll interposed therebetween, as seen in Fig. 1 and within which said vertical legportions of angle members [4.

Extending from the o-uterface of-one ofsaid jaws ll, and in a perpendicularrelation therewith, is boss iii provided with a central threaded bore :for receiving in a threaded engagement, screw 2E3, having head 21. Extended throughv said head 2i, ina transverse relation, is across bar :22, by means of which saidscrew .20 may be rotated in either direction for disengaging the.

same from said vertical leg portions of vangle members It. or for bearing thereagainst for holding a pair thereof with the interposed tie II in afirm clamped relation. 1 I

Formed in the body portion [5 of the clamp tion with recess l6,-and has thewidthj-substan 3 tially corresponding to the thickness of tie II, and within which the end of the latter is receivable, as is seen in Fig. 1. The trapezoid formation of said recess 23 permits various angular adjustments of tie H within said recess 23, as is indicated by dotted lines in Fig. 2.

Made in the body portion l5 of the clamp, and in a transverse relation with recess 23 is aperture 24. Tie H at its ends is provided with similar apertures, one of which registers with aperture 24, for receiving pin 25 therethrough when the clamp is in an operative position with tie ll. By this arrangement tie l l is bound to the clamp, and when two clamps are engaged to tie ll, one at each end thereof, the latter will be capable of holding a pair of spaced panel form walls in a rigid relation, preventing shifting thereof under the pressure of the poured cement mixture between the form walls.

Communicating with said recess 23 and extending through the adjacent end of body portion l5 of the clamp is recess 26 of substantially rectangular formation and of the width on transverse cross-section corresponding to that of recess 23. That recess 26 is designed for receiving therewithin ties longer than ties H, and narrower than the latter. If such ties are snugly fitted within recess 26 no angular adjustment thereof will be possible. If however such ties are narrower on horizontal plane of the clamp than recess 26 some angular adjustment thereof will be possible.

From the hereinabove description it will be readily seen that the clamp herein disclosed binds a pair of adjacent panels in a coplanar relation thereof, by rigidly engaging the vertical leg portions of angle members i4, thereby permitting erection of a form wall from said panels l0 when the latter are laid in an edge to edge position. Simultaneously the clamp clamps tie H to a pair of panels by rigidly engaging the former with said vertical leg portions of angle members 14, which is accomplished through jaws I1 and screw 20, and lastly the clamp rigidly engages tie therewith through the medium of pin 25 thereby preventing shifting of a pair of panel form walls to or away from each other.

clamp is removed from panels l0 and ties H by loosening screw and withdrawing pin from aperture 24. This will disengage the clamp from panels i0 and ties H, and thereupon panels Ill may be readily removed from the faces of the concrete wall. The ends of ties H projecting from the faces of the concerete wall may be broken oil? as shown in my said co-pending application.

The occasion for angularly adjusting the clamp with relation to tie Ii, and accommodating the latter in its angular adjustments within recess 23, arises when the form walls are erected at an incline. In that instance ties H cooperating with the vertical angle members M will not be in a perpendicular relation with the said angle members or with their panels, but will remain in an oblique relation therewith. This necessitates angular adjustment of the clamp with relation to tie II, and the trapezoid form of recess 23 permits such an adjustment.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

1. In the art of binding a pair of concrete wall form panels, each of said panels being provided on its margin with an angle member, the outwardly extending leg portion of said angle memher in each panel being substantially in a perpendicular relation with the body of the panel, with a Wall form retaining tie passed between the margins of a pair of adjacent panels and between a pair of adjacent leg portions of said angle members in a pair of panels, said tie extending beyond the outer edge of said leg portions of said angle members, a clamp for retainmg a pair of said panels in a rigid mutual relation and for binding said tie thereto, comprising a block, a pair of spaced stationary jaws at one end of said block, a pair of adjacent leg portions ofsaid angle members on a pair of panels with said tie interposed therebetween being received between said jaws, means in said jaws for rigidly binding said leg portions and said tie on the transverse plane thereof, said block having a recess therein extending from said jaws lengthwise thereof receiving one end of said tie therein, and means extending transversely through said block and said recess and pivotally engaging the end of said tie.
