This invention relates to concrete forms and more particularly it relates to an improved de vice or waler support for supporting walers for concrete forms.

Prior to my invention, wooden cleats have been used to support walers. l x 6- plank is cut off about-'a foot long, and four or ve nails are used to vnail the cleat to the stud under the waler. The removal of this form of wooden cleat usually means a complete loss thereof, because by the time it is knocked off it usually splits, and notv only is not suitable for reuse, but the parts left lying around with nails sticking up on the job create a job hazard.

Also some contractors naill their walers together which means that bothv the upper and lower walers break joints at. the same place. Although the walers may be supported on the clamp, this is not a satisfactory system of erecting walers. Still others toe-nail the walers to the stud. This is alsov objectionable since it breaks up the lumber when the toe-nailing breaks loose, splitting out the lumber, etc.

It is therefore a principal object of the invention to provide an improved waler support overcoming the disadvantages of conventional wooden cleats.

l Another object of the invention is to provide a waler construction inl which the joints may be broken giving a more continuous support.

A further object of the invention is to provide a demountable waler support for waler construction in which` the walers and waler supports may be readily erected in the construction of concrete forms and dismantled for further re-,use Without destruction.

Another object of the 'invention is to provide an improved waler construction which eliminates the necessity of building scaffolding to install clamps and the placing Aand replacing of Wooden cleats.

Still another object of the invention is to provide an improved waler support which may be rotated out ofY the way when storing sections of concrete forms to which they are applied.

A further object of the invention is to permit, with the use of the improved waler support, breaking. joints of upper and lower walers at different places.

The invention also has amongits objects the production of an improved waler support which is. simply fabricated, reliable,durable, economical, inexpensive, easily installed and satisfactory for.v its purpose.

In order to.. accomplish the various objects of Usually a 1 X 4" or 3 claims. (ol. 25-131) 2` y the invention, I have provided an improved waler support fabricated in the form of a trapezoid from relatively light gauge sheet metal which will support all the necessary loading or ,weight thatrwill be placed on a waler with the use of only two nails. It is so constructed that it.may be rotated or swung back! out of the Way by pulling the lower nail and left inu place onv thestuds of the form for re-use after the walers are removed. The waler support isv provided, forexample, with Y two projecting members that abut against the stud for alignment and help'take the load that is `placed upon the waler itself. The metal waler support has holes on either side andthe gauges are located so' that a substantially symmetrical waler support' is formed so that it may be reversed and usedv on the opposite sides of the stud.

Many other objects and advantages of the con-. struction herein shown and described will be Aobvious to those skilled in the art from the disclosure herein given To this end my invention consists inv the novel construction, arrangement and combination of parts herein shown and described and more para ticularly pointed out in the kappended claims.

Referring now to the accompanying drawing forming part of the specification:

Fig. 1 is a view in elevation` taken through a concrete form, partly in section, illustrating the use of. the waler support of my invention;

Fig. 2 is an enlarged end view of the waler support of the construction illustrated in Fig. 1;`

Fig. 3 is an enlarged plan view of the construc-4 tion illustrated in Fig. 2; Y

Fig. 4 is an enlarged elevational lView .ofa modified form of waler support, illustrating the stop for larger walers; and` y Fig. 5 is an enlarged view of a modified construction for a projection for the waler support.

Referring now more particularly to the draW-' ing, waler supportsA |-0 are shown ainxed to studs Il of a conventional concrete form construction I2 which is formed by a plurality of oppositely positioned form members, the boards of each form` being connected by nailsv or the like,or in any suitable manner, with the exteriorly vertically extending studs Il, and the studs being braced by longitudinally extending waler members 13. Y

The forms may be of any desired length and height,l and the oppositely positioned; form members are adapted to be dismantled and used repeatedly for pouring concrete walls of the same or different thicknesses, and the' forms may be used either for the construction of vertical or battered walls. Y'I-he forml members are fastened- 3 together by a plurality of conventional fastening devices or form tie rods I4 similar to that shown in the drawing, the devices being suitably spaced, vertically and longitudinally, to provide requisite form rigidity.

The waler support I of my invention is preferably fabricated of l4 gauge sheet metal or 1/8 aluminum in the shape of a trapezoid as shown in Figs. l and 4. rIhe waler support I0 is formed with an upper edge "I adapted to support the waler-construction I3 in either position of the support on opposite sides of the form or of a stud to which it is afxed. Both the upper edge I5 and lower edge I6 are formed with struck out projections IT adapted to abut a front edge of the stud to which they are `aiixed for alignment, and to help take the load that is placed on the waler construction I3. 'Lateral' edges I8 are preferably formed, as shown, so that the waler supports may be sheared from strip metal the width of a waler support with a minimum loss by alternating or reversing the pattern. It is also within the scope of the invention that the edges may be simply sheared straight across to fabricate a maximum number of supports with a minimum length of strip material Vfrom which ,the supports are formed. The shape of the edges shown ispreferred to reduce the sharp corners and minimize the accident hazards due to unnecessarily sharpv corners. Nail holes I9 are symmetrically positioned along the edges I8 through which preferably two double headed nails 2D are drivenk for afxing and erecting the waler supports I0 to their respective studs I I. Referring to Figure 4, there is illustrated a modified waler support I which is similarly constructed as the waler support described with reference to Figs. l, 2, and 3, but is provided with a stop construction 2| which may be affixed by spot welding, riveting, or the like, as indicated at 22, to the waler support I0 for receiving, for example, 4 or 6" walers I3', depending upon the size of the concrete form construction to be braced. The stop construction 2l is preferably formed from the same gauge sheet metal as the waler support to the shape shown With an upstanding projection 23 to limit the outward movement of the waler I3 when erected in place upon the waler support.

In Fig. 5 there is illustrated another form 24 ofv a'waler support similar to that described with reference to Figs. l to 3, but illustrating another example of a modified projection I1.` In this embodiment, the blankfor theA waler support is substantially triangular in shape. The. portion'25 is slit at 26 after which it is formed to the solid lines as shown by rst bending a portion 21 along the line 28 at right angles to the portion 29 and then forming the edges so that the triangular portions take their respectivepo'sitions 2 and 29 completing the projection III-1.Y v An upper lug or projection I'I for the modified waler support may be Vsimilarly formed as ypreviously described'or so formed from the metal of the support to provide a suitable projecting member to gauge the waler support upon a stud to which it is affixed. It is also to be understood that suitable gauge members may be provided by welding or otherwise affixing separ'ate members tothe support to provide the projections without departing from the scope of t-he invention.

In constructing a concrete form using any of the prefabricated waler supports described, the waler supports III are aixed to the studs where the tie rods or fastening devices I4 are to be erected. Each waler support is nailed in place preferably with two double headed nails 20. The walers I3 are erected in place on the waler supports. Each securing device I4 is then erected in place, as shown. These securing devices are of conventional construction comprising threaded waler rods 30 projected through aligned holes in the forms I2 and aixed to an intermediate rod or she-'rod 3l. "The waler rods may be temporarily supported by double headed nails 32 driven through holes in the waler rods or through, for example, a cotter key 33, positioned in a hole in the waler rod to hold the form members in xed, spaced-apart relation. The nails prevent such rotation of the members 30 as might occur when the end brackets 34 are positioned in clamping engagement with the waler members I3 by the threading of the Wing nuts 35. The brackets 34 are preferably fastened in vertical position to the waler members by nailing through suitable apertures (not shown). -It is to be understood that the nails or other securing devices are removed before attempting to rotate and release the members 30, as is Ywell understood in the art. Stud marks 36 are formed on the waler rods 30 to indicate the proper depth of the rods Within the form.

The forms constructed with the waler supports described may be raised and relocated, as is well understood in the art. When the forms are dismantled for re-use or stored, the waler supports may be rotated, for example, to the dotted position 31 within the outline of the stud, Fig. l, by removing the lower nail 20; and if necessary, loosening the upper nail, after which the upper nail may be resecured to prevent rotation of the waler support from its storage position.

It is thus obvious that there has been disclosed a simple and inexpensive form of waler support which eliminates nailing walers together and toe-nailing to the studs. It also eliminates building scaffolding where men can Work on walers. Furthermore, placing and replacing of wooden cleats is eliminated. Also, there is no necessity for cutting upper and lower walers to match at breaking points at one place. Occupational hazards of stepping on nails in removed cleats is also avoided. Expended material due to Wrecking is materially eliminated.

. The improved waler supports of this invention Work equally well on vertical or battered walls. Furthermore, these supports permit breaking joints of upper and lower walers at different places. Any length of waler may be used without cutting. In storing form sections, the waler supports may be rotated out of the Way in piling. Also, they are demountable and no wrecking is necessary permitting greater salvage of lumber.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same Without departing from the spirit of my invention; hence, I do not Wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned. y
