ABSTRACT:
A strongback attachment system for temporarily attaching a reinforcing beam or the like to a poured concrete structural member includes an insert adapted to be set in the poured concrete member. The insert has a body for creating a void in the concrete structural member and a base for supporting the body in spaced relation above a floor of the concrete structural member. The base has a pair of leg members in which a portion thereof extends through the body so as to be free of concrete. A bolt is also provided for securing the reinforcing beam to the concrete structural member, where the bolt includes a shaft with a threaded end and an opposite end terminating in an engagement head. The engagement head is adapted to be releasably engaged by the leg member portions extending through the body. The leg member portions extending through the body of the insert are substantially parallel and the engagement head is configured to pass between the leg member portions when oriented in a first position and to become retained by the leg member portions when oriented in a second position. The strongback attachment system also includes a spring biased portion on the bolt adjacent the engagement head to bias the bolt away from the leg member portions and thereby promote the retention of the engagement head by the leg member portions.
