A portable, handheld implement for disjoining protruding concrete ties from reinforced concrete, the handheld implement adapted to apply successive bending and breaking forces to concrete ties, rebar, and the like. An L-shaped head, or chevron-shaped head, in some embodiments, receives the protruding concrete tie and coacts therewith to shear a concrete tie or rebar from a typically planar concrete surface using successive, longitudinally-applied handheld force. A concrete tie is inserted into a recess in the head of the implement designed to securely receive it. Some embodiments of the present invention comprise two L-shaped heads, on at either end of the handle.

A sleeve assembly is provided comprising an inner tubular member and at least one outer sleeve that receives at least a portion of the inner tubular member. The outer sleeve may longitudinally telescope with the inner tubular member to move between a non-expanded position and at least one expanded position. In some embodiments, the inner tubular member comprises a first locking component and the at least one outer sleeve comprises a second locking component that interlocks with the first locking component to secure the outer sleeve in the non-expanded position and/or at least one expanded position. Related methods for making a sleeve assembly are also provided.

According to one embodiment an extractor is provided that comprises a stem with a handle at one end and a conical spacer engagement device cooperating with the conical spacer for extracting it from the concrete wall at the other end. The extractor also comprises a mobile element which is displaceable by a user along the stem between a retracted position to which the mobile element is moved in order to contribute to the extraction of the conical spacer, and an advanced position to which the mobile element is moved in order to push the conical spacer, releasing it from the conical spacer engagement device. When the conical spacer engagement device is fixed to the conical spacer, then the mobile element is moved to the retracted position, the corresponding conical spacer being extracted. The mobile element is then moved again to the advanced position, releasing the conical spacer from the conical spacer engagement device.

A tie rod puller including a pull housing, a clutch assembly and a clutch assembly housing is disclosed. The tie rod puller accelerates the process of pulling tie rods and installing key plates. The pulling of tie rods better secures the panels of a structure under construction to improve the integrity of a structure. The clutch assembly movably rotates a nut as a tie rod is being installed. The clutch assembly includes a stopper to prevent the nut from moving too far back. The clutch assembly is to hold and move a tie rod upon pulling of the tie rod and installing a key plate onto a wall. The clutch assembly housing includes a plate, which receives a key plate with a magnet. The plate includes brackets to stabilize the tie rod puller. The tie rod puller is preferably operated by automatic means such as by an impact drill.

When the conical spacer engagement device is fixed to the conical spacer, then the mobile element is moved to the retracted position, the corresponding conical spacer being extracted. The mobile element is then moved again to the advanced position, releasing the conical spacer from the conical spacer engagement device.

A device for removing form ties from concrete. The form tie removing device includes a housing having an open first end and a second end, wherein the housing defines an interior volume that can receive a form tie. One or more apertures are positioned along the housing, wherein the apertures allow a user to view the position of the form tie within the interior volume of the housing. A tool bit extends from the second end of the housing, wherein a distal end of the tool bit can be inserted into a power tool, such as a rotary drill or impact driver. In use, a form tie is positioned within the housing and the tool bit is inserted into the power tool. Upon activation of the power tool, the housing rotates and releases the form tie from the surrounding area, such as concrete.
