摘要

A tool for concrete construction has a base provided with downwardly open channel for receiving an expansion joint with movement of said tool effecting straightening of expansion joint. Generally upwardly directed flanges are structured to be cooperating with a straight edge for facilitating straight movement of tool during straightening of expansion joint. The tool may also be employed to establish control joints. Related methods arc provided.

1. A hand tool for concrete construction structured to
straighten an expansion joint in a concrete slab comprising a base having a downwardly open expansion joint receiving channel and a pair of relatively spaced generally upwardly projecting outer flanges, a handle secured to said base, said base having first and second adjacent base elements, a pair of inner generally downwardly extending flanges cooperating to define said downwardly open expansion joint receiving channel, thereby manual engagement of said handle and insertion of said expansion joint in said expansion joint receiving channel will permit tool movement to straighten said expansion joint, a base plate interposed between said first and second adjacent base elements and said handle, said first and second adjacent base elements fixedly secured to said base plate, said upwardly projecting outer flanges being oriented generally perpendicular to a plane passing through said base plate, and said generally upwardly projecting outer flanges structured to be in contact with a straight edge for guiding said tool
