INVENTOR TTORNE Patented Qct. 6, 193i UNITED STATES ROSC'OE I). FARMER, OF OKLAHOMA CITY, OKLAHOM JOINT FORM FOR PAVING Application filed January 23, 1930.
My invention relates to forms for joints in concrete paving.
The obj ects of my invention are to provide a device of this class which is new, novel, ,5 practical and of utility; which may be used on concrete paving or concrete paving base; which will form a straight line of cleavage in the top of the pavement thus causing any expansion breaks which might occur to follow a straight line; which will weaken the pavement vertically on said line of cleavage without disconnecting the. pavement upon each side of the line; which may be used as a center strip longitudinally with the pavement and also for forming t-ransverse joints; which will prevent the usual voids or honeycomb which occur in pavements adjacent the usual joint forms; which will permit the use of reinforcing steel across the joint; which 20 will provide a means for anchoring thereinforcing steel across such joints; which will save material over the usual joint form; which will thus save in freight and transportation expense; and, which will vbe efiicient in accomplishing all the purposes for which it is intended.
At the present time it is' the usual practice in forming pavement joints to use a Vertical form which extends entirely through the 30 pavement. The usual form is sometimes provided with ay longit-udinal groo-Ve or other deformity for reaking the Vertical plane of cleavage, the object being to form a groove in the pavement on one side of the form, and a tongue on the other side registering with the groove. There is no communication provided for between the portions of pavement lying on each side of the form. Great care must he exercised in puddling the concrete on each side of the form in order to prevent Voids being left in the concrete.
My form not only breaks the plane of cleavage in the usual manner, but also proi Vides a communication of the concrete through the bottom portion of the form. It permits the laying of reinforcing steel through the form and also provides a means for anchoring the steel to the form and spacing it from the sub-grade.
With these and other objects in View as Serial No. 422,849.
'will more fully appear, my invention consists inV the construction, novel features, and combination of parts hereinafter more fully described,-pointed out in the claims hereto appended, and illustrated in the accompanying 155 one-sheet drawing, of which, l
Figure l is an'elevational view showing a tie bar anchored through the form;
' Fig. 2 is a fragmentary plan view of a pavement showing the form in place; and 00 F ig. 3 is a sectional view along the line 3-3 of F ig. 2. I
Like'characters of reference designate like parts in all thel figures.
It is understood that Various changes in the form, proportion, size, shape, weight and other details of construction, within the scope of my invention may be resorted to without departing from the spirit or broad principle of my invention and without sacrificing any of the advantages thereof; and it is also understood that the drawings are to be interpreted as being illustrative and not restrictive.
One practical embodiment of the invention as illustrated in the drawings comprises:
A strip 1, of sheet metal or the like having a straight top edge :2, a longitudinal corrugation 3 lying below and paralled with said edge 2, and a bottom edge 4. Cut upwardly in said bottom edge 4, are a plurality of spaced beveled sided notches 5 their top straight edges 6 lying below and parallel with said corrugation 3. The portions of said strip 1 i lying between said notches 5 form legs 7. 'V
Each alternating one of said legs 7 is provided with a Vertical corrugation 8 for strengthening the leg. Each other alternating one of said legs 7 is provided with a perforation 9, and slightly therebelow has a square aperture 10 cut therethrough. The metal is not severed from strip 1 at the top of said aperture 10, but is turned outward at right angles to the plane of said strip 1. A portion of the outturned metal is cut trans- Versely from each side as shown at 11 and its outer end portion is turned upward to form a clamp 12 for receiving a steel tie bar 13 projected through said perforation 9. Clamp 12 forms a means for attaching said ooncrete. yhe direction inwhieh'sai elainpsf V V12extend' from said strip V1 is alternate lnpo11l 'each alternatingleg 7.
VIn operation, strip 1 is placed'verticall at the point where the joint is desired, Wit legs 7 restingl upon the sub-gracie. VBars 131 are insertedthrough perfor'ations 9, andV clamps 12 bent therearound with. a'pair of Crete with aweakened Vertical line of cleafv ofthe Vslab which extends throug with reference to the was broken.
swe at the` point where Athe form is used. iis will cause any break which may occur in the Valab dueto ex ansion and contraction. to follow the line o weakness. The ortioi sal notches 5 andV apertures 10, ifbrokexnwill break in` an irre ular p1ane,thus preventing the broken slab rom any Vertical movement portion from which it Obviously, the invention isV susceptible of embodlment in forms other than that which is illustrated m the accompanyln drawmgs and deseribed hel'em, and app icable, Vfor f uses and' purposes other than as detailethand aaI ation of? the lV thei'efore consider as my own all such modifications and adaptations and other uses of the form of the device herein described as .fail'ly fall Within the scope of my invention.V
Havin thus described my invcntion, What is claimed and desired to be secnred by Letters Patent, is:
I 1. A joint onn foi` avement2 embodying a. thin strip of snita le material having a straight upper edge and havin a longiinal and continuous corl'ugatlon below and parallel to said edge said strip having a plurality of sl'iaced legs downstanding from and in a plane With itsV body, Vand ontstand; ing means Vcarried by some of said leg'sfor "corrugf I o fmeans carried otherof saidfjleg fory De) w l'ysupporting ati-e bar laterally therctln'zongh,V` r. i V'Said means forined bya part of thezle'g turned turned part bentaroundsaid bar.
