I~PROVED W~LER BRACKET
I. DESCRIPTION
Background _ the Invention F~eld of the Invention. The present invention 5 relates generally to a waler bracket and, more par-ticularly, pertains o a waler bracket for use with a concrete wall orm.
Descrlption of the Prior Art. A number or waler brackets or clamps have appeared in the prior art for 10 securing concrete wall forms in place. The panels used in the molds are maintained in longltudinal alignment by means of relatively heavy stringers or walers which extend hori-zontally across the pan~ls while bearing against t'ne ver-tical members. The walers generally have associated 15 -therewith means for wedging the walers firmly against the panels to keep them straight with respect to each other.
U. S. Patent 2,879,576 shows a waler clamp which forces a heavy stringer against a vertical frame bar by using a wedge to exert force on a tie rod secured to the vertical member.
U. S. Patent 3,547,398 shows a different form of brac~et for use in constructing concrete forms held in a spaced relationship by ties. The brackets shown in the patent are generally used in association with specific tie 25 members also shown.
U. S. Patent 3,347,510 shows a waler bracket w~ich is secured to the panel to be straightened by a tie rod, and the wedging force is applied by driving a nail into an aperkure to force a portion of the bracket into contact 30 with the waler to force it against the panel surface.
U. S. Patent 3,584,827 pertains to a three-part waler clamp assembly which is secured to a vertical margi-nal frame member and tie rod.
U. S. Patent 3,655,162 relates to a waler clamp 35 or application to the protruding end o a tie rod to securely clamp a waler against t~e outer side of a series of upstandlng edge-to-edge wall form panels. U. S; Patent 3;724,806 is another form of the same waler clamp.
U~ S. Patent 3,712,576 relates to a waler clamping assembly which, in one form, is applied to steel studded concrete wall form panels to clamp walers in position against the panels and, ln another form, is directly applied to the waler to clamp a pair of strongbacks against the waler.
My improved bracket is less complex than the p~ior art bracXets and is, therefore, simpler to manufac-ture and easier to use than brac~ets according to the prior art.
Summary of the Invention The general purpose of the present invention is to provide a waler bracket which can be easily manufactured and installed to secure a waler against vertical panels used in concrete wall forms~
The waler bracket or clamp has a frame with a first su~stantially vertical portion constructed and arranged for engaging at least one stud projecting from the face of a panel. The frame has a substantially horizontal central portion constructed and arranged for supporting a waler and a second substantially vertical portion on the oposite side of the central portion from the first portion.
The central portion of the frame also includes a slot for receiving a wedge inserted therein.
The waler clamp also includes a wedge arranged for insertion through the slot in the central portion of the frame between the second portion of the frame and the face Of the waler to force the waler lnto aligning contact with the panel.
Brief Description of the Drawings Figure 1 is a perspective view illustrating a per-ferrred embodi~ent of the present inventlon mounted for securing a waler against ~ planar surface;
Figure 2 is a side view of a waler bracket according to the present inven-tion;
Figure 3 i5 a front view of the clamp, and Figure 4 is a side view of a clamp securing a waler against a planar panel.
Detailed Description of the Invention Figure 1 shows a clamp 10 mounted for securing a waler 12 against the face 14 of a panel 16. The waler clamp 10 ls comprised of a main frame means 18 which has a substantially horizontal central portion 20 and a first vertical portion 22 and second vertical portion 24 at oppo-site ends thereof. A reinforcing piece or gasset 26 is welded to the bottom of frame 18, serving to reinforce the frame and prevent a change in the angle between the substantially horizontal portion 20 and the substantially vertical section 22. The central portion.20 of the Erame 18 includes a slot 28 which is constructed and arranged to receive the narrow portion 30 of a wedge 32.
The widest portion 34 of wedge 32 has a width which exceeds the length of slot 28. Wedge 32 has a thickness slightly less than the width of slot 28. An L-tab 36 is welded to the underside of the frame 18 and is aliyned with slot 28 to receive the narrowed portion 30 of wedge 32 as shown in Figure 2. The wedge 32 also includes a cylindrical tip portion or wedge keeper 38 which is welded to the narrowed portion 30 to retain wedge 32 in slot 28 and provide a larger bearing surface for the tip 30 of wedge 32 in the keeper 36.
Figures 1 and 4 show the clamp in use securing a waler 12 to a panel 160 The wedge 32 is angled to bear against the substant.ially vertical lip 24 of the frame 18 and against the outs.ide edge of waler 12. The wedge is driven firmly into the slot 28 and thereby applies a substantial force against the face o walex 12. Because frame 18 is anchored by stud 40 to the panel, the waler is secured to the panel by the wedging force. A sexies of waler clamps 10 can be utili~ed on adjacent panels to align 36~, a waler with the panel face and thereby straighten the panels and hold them in a desired alignment.
