Abstract
Abstract A device for transferring stresses to a rod having transverse ridges. In the preferred form, the device includes a U-bolt embracing the rod and traversing a member bearing against the rod, and also includes a locking device engageable with the legs of the U-bolt on the opposite side of the bearing member from the reinforcing rod. The U-bolt is receivable against at least one of the ridges to provide restraint against axial slippage.

Total Claims: 4
Claim 1
Independent Claim
137 words
In combination with a reinforcing rod and a bulkhead intersected by said rod, a clamp assembly for securing a bulkhead in position preparatory to pouring concrete, comprising: an angle bracket having one flange thereof securable to a bulkhead, and the other flange thereof disposed to engage said reinforcing rod tangentially with respect thereto, the axis of said bracket being transverse to said rod; a U-bolt adapted to embrace said reinforcing rod and engage said other bracket flange; securing means engageable with said U-bolt to clamp said other bracket flange between said reinforcing rod and said securing means; and wherein the legs of said U-bolt are provided with aligned discontinuities of reduced thickness, and said securing means is a wedge having a portion engageable with said discontinuities, and a base portion adapted to engage said other bracket flange.
