Abstract

An inseparable waler clamp assembly for convenient manual application to the protruding end of a tie rod for securely clamping either a single or a dual waler hard against the outer side of a series of upstanding and edge-to-edge wall form panels. In one form of the waler clamp assembly, the design is such as to accommodate attachment to a cylindrical tie rod or tie wire having a button-like enlargement on one end thereof.

Claims

1. A three-piece waler supporting and clamping bracket assembly designed for attachment to a horizontal tie rod one end of which projects outwardly from one side of a concrete wall form and presents an inwardly facing reaction shoulder, said bracket assembly comprising a U-shaped bracket having upper and lower horizontal legs and a connecting bight portion, the distal end of said upper leg being provided with an outwardly facing reaction shoulder designed for interlocking engagement with said inwardly facing reaction shoulder on the tie rod, there being vertically aligned upper and lower openings in said legs respectively near the base portions thereof, a thrust plate slidable on said lower leg and having its forward end region overhanging the distal edge of the latter and its rear end region overhanging an edge of the lower opening, the extreme forward end of the thrust plate being engageable with the outer surface of the form side when the reaction shoulders are in interlocking engagement with each other, and a tapered wedge projecting vertically through said aligned upper and lower openings and adapted when driven downwardly to have the upper portion thereof above said upper leg bear against the outer side of a waler board for forcing the latter against the form side, and the lower portion thereof bear against the rear overhanging end of the thrust plate in order similarly to force the latter forwardly and against the form side, said lower portion of the wedge being further adapted to bear against the outer side of a second waler board which is interposed between upper and lower horizontal legs for forcing the latter waler board against the form side.

2. A three-piece waler supporting and clamping assembly as set forth in claim 1 and wherein the inwardly facing reaction shoulder on the projecting end of the tie rod is formed by way of a button-like enlargement, and the forward end of the upper leg has an upwardly extending part with an open-ended slot therein adapted to straddle the tie rod and lie behind said enlargement, the slot-defining portion of said upwardly extending part forming an outwardly facing reaction shoulder for interlocking engagement with said inwardly extending reaction shoulders.
