Abstract
Abstract A cooperating she-bolt and torque wrench assembly wherein the she-bolt is provided inwards of its outer extremity with a flat web and the torque wrench is forked so that it may be caused to straddle the web. A crank arm on the torque wrench facilitates spinning of the wrench for the purpose of unthreading the shebolt from its associated tie rod when the latter is embedded in a mass of poured concrete.

Claim 1
Independent Claim
347 words
In a concrete wall form, in combination, a tie rod assembly including a tie rod adapted for embedment in the concrete wall resulting from such form, and a she-bolt threadedly connected to the outer end of the tie rod and having a cylindrical portion adapted to project outwardly from one side of the wall and also adapted, upon rotation in one direction, to become unthreaded from the tie rod for extraction purposes, said projecting cylindrical portion being provided with a flat web adjacent its extreme outer end defining a terminal button head outwardly of web, and a torque wrench for rotating said she-bolt in said one direction, said torque wrench comprising an elongated cylindrical body portion having a crank arm adjacent to its proximate end, and having a transverse notch adjacent to its distal end and a longitudinal notch extending inwards from said distal end and intersecting said transverse notch, thus defining a pair of laterally extending fork tines adapted to straddle said web in driving relationship when the button head is disposed in said transverse notch and the she-bolt and body portion are in coaxial relationship, the distal end of said cylindrical body being formed with a cylindrical socket having a diameter slightly greater than the diameter of the body portion of the she-bolt, the longitudinal extent of said transverse notch being greater than that of the button head, and the depth of said socket being less than the width of the fork tines in a longitudinal direction, thus providing a bottom wall for the socket, said wrench being capable of limited axial shifting movement with respect to the she-bolt between an initial position wherein said fork tines straddle the web, the button head is in close proximity to the fork tines and the cylindrical body portion of the tie rod is disposed exteriorly of said socket, and a terminal position wherein the fork tines also straddle the web, the button head is remote from the fork tines, and the outer end of the cylindrical body portion of the tie rod is disposed within the socket.
