a This inventionrelates to concrete forms, and more particularly to brackets adapted to be secured to the vertical stringers of wooden concrete forms for holding the lower walers in position.

. In setting up wooden concrete forms, two vertical walls of horizontal wooden boards are commonly employed between which the concrete is poured. These boards are usually nailed to and supported at spaced intervals by vertical studs or stringers abutting the outer surfaces of the walls. Horizontal studs or walers, usually placed in pairs, are then nailed to the stringers at spaced intervals. The walls are maintained in fixed spaced relationship by means of tie rods or spacer rods which pass through the concrete and between the pairs of walers. These rods may have flanged ends for holding key plates which abut the outer surfaces of the walers.

This comparatively primitive type of erection is subject to various deficiencies. Usually, scaffolds must be built to support the workers while the walers are being placed in position. The walers are usually toe-nailed to the stringers or fastened in some other rudimentary manner whereby dismantling of the forms is difficult and causes much damage to the walers, stringers, etc. Being subject to splintering, splitting, chipping, etc., this type of erection heretofore employed has been unreliable in presenting a hazard to both life and property. Various other disadvantages are universally recognized in the trade.

One object of this invention is to provide a waler bracket for holding the waler in position which may be quickly, simply and economically installed, manipulated, assembled and dismantled, and which is durable, compact and simple in construction and economical in manufacture.

Another object of this invention is to provide a waler bracket which may be safely used as a ladder whereby to eliminate the necessity of building the usual scaffolds.

A further object of this invention is to provide a waler bracket which will eliminate most of the cutting, chiseling, drilling and/or nailing which attends the usually employed method of erecting concrete forms and which will eliminate the usual damage to walers, stringers, and the like.

A still further object of this invention is to provide a waler bracket which is unitary and without movable parts subject to mechanical failure and disalignment.

The accomplishment of the foregoing objects is made possible by the invention described hereinafter and in the attached drawing which illustrates a preferred embodiment thereof.

3 Claims. (Cl. 248-216) V 2 In the drawing; a Fig. 1 represents a perspective view of a wooden concrete form showing the two retaining walls,

each with an abutting stringer and a pair of walers, and a pair of the waler brackets illustrative of the instant invention installed on the V stringers.

tion, looking in the direction of arrow A of Fig. l.

the direction of arrow B of Fig. 2.

Referring now to the drawing in which like-reference numerals indicate similar parts in the several views, reference numeral l0 indicates the parallel walls of wooden boards for retaining the concrete therebetween, H indicates the vertical stringers supporting said walls, 12 indicates the upper walers and I3 indicates the lower waler Spacer or tie rods l 4 hold the walls in fixed spaced relationship, and have flanged heads l5 for holding key plates I 6 in locked position.

The waler brackets which are the subject of the instant invention are indicated generally by reference numeral l1, and as shown are fabricated from a plate metal blank to produce an integral unit. Particularly, the brackets are fastened to stringers I l at one vertical edge thereof, preferably by means of one or more doubleheaded common nails It. A vertical flange I! at the opposite vertical edge of the bracket is fastened to the outer surface of the lower waler I! by means of nail 20 as the said waler rests in recess or depression or cut-out 2| in the upper edge of the bracket. For further support, a lateral L shaped upper holding arm 22 is cut out and shaped from the body of the bracket for attachment to the outer surface of stringer I l by means of nail 23 and to the opposite side of the stringer by means of nail 24. A lateral L shaped lower holding arm 25 is cut out and shaped from the body of the bracket so as to have a pronged end 26 which is driven into the outer surface of the stringer.

The preferred embodiment of the invention as described hereinbefore and in the annexed drawing is illustrative only and various changes and modifications therein will be obvious to a worker skilled in the art. For example, the holding arms may, if desired, be welded or otherwise attached to the body of the bracket, although this modification is less desirable than the one shown in the drawing since a different type of operation is required in the attachment and the strength at the joint is or may be affected. However, extra strength would be gained in that the body of the bracket would not be cut out.

Fig. 3 is a front view of the-same, lookingin Similarly, flange l9 may be bent in the opposite direction if desired. The relative vertical positions of arms I9 and 25 may be reversed, if desired, though this is less preferable than the positions depicted in the drawing. The prong 22 may have any other suitable shape or form. Likewise, while Fig. 1 shows right-handed and lefthanded. modifications of the bracket. this manner of illustration is mainly for the purposes of better disclosure of the inventive features of the brackets, since in actual practice, the brackets on both sides of the retaining walls would be identical, whereby the bracket shown in Figsc2 and 3 (see directional arrow A in Fig. l)- would be attached to the far side of the stringer in Fig. l.

Double-headed nails have been described asemployed for fastening the bracket to the stringer and walers mainly to allow easy removal in the dismantling operations; but any other suitable manner of fastening the stringer and walers may employed. Similarly, the bracket is preferably :3 pressed metal unit of a guage dependent on the strength, facility of fabrication, and economy dealthough any other suitable material may beused.

As will be obvious from the foregoing description; thebracket of the instant invention enables the accomplishment of the objects stated herein. The bracket is quickiyandsimply installed by fltting

arms

22 and 25 on stringer H in the desired location with the upper edge of the bracket in horizontal alignment" with the'tie' rod ll, driving prong 26 into-thestringer so that the arms abut the outer surface of the stringer, and

wthen driving'l'rr nails I8, 23 and N". The bracket may nowbe used as a ladder until ready to receive' the waler, which is simply dropped into and fastened with nail 20 in flange f5.

Various other modifications and variations of the invention will become apparent to a worker skilled in the art, and such modifications and variations are to be regarded as within the purview of this application and the spirit and scope of the appended claims.

What is claimed is:

l. A waler bracket comprisinga vertical plate provided with means along: vertical edge thereof forattachment to a side of a vertical stringer, a flange along the opposite vertical edge of said plate provided with means for attachment to the outer surface of the waler, a depression in the upper edge of said plate adjacent said flange for receiving said waler, an L shaped arm projecting laterally fromthebody of said plate adapted to abut the outer surface and opposite side of said stringer and be secured thereto, and a second arm projecting laterally from the body of said plate provided witha prong, adapted to be driven into the outer surface of said stringer.

2. The bracket of claim 1 in which said. second arm is below said L shapedarm.

3. The bracket of claim 1 in which said arms are cut out and: shaped from the body of the plate whereby the bracket is an integral unit.
