A method of using the system includes the steps of positioning the temporary concrete barrier at a desired location on the bridge deck; drilling a mounting hole in the bridge deck; filling the mounting hole with epoxy; inserting the barbed nut and two-part sleeve into the mounting hole and epoxy; inserting the bolt into the two-part sleeve and the barbed nut; waiting for the epoxy to set, tightening the system so that the temporary concrete barrier is held in place with respect to the bridge deck; loosening the system and removing the concrete harrier when it is no longer needed; and filling the mounting hole with epoxy after the concrete barrier is removed.

Abstract: An anti-rotation lock device for preventing movement in an assembly which includes an endpiece carrying a thread screwed into a tube together with a nut suitable for being screwed on the endpiece, the lock device including a first washer provided with an anti-rotation lock component and a second washer having at least one key and wherein the first or the second washer includes a lug, and the faces of the first and second washers are configured to adjustably lock them mutually against rotation. The device further includes a third washer which includes a member for locking the nut in rotation and an outer periphery of the third washer has a tab adapted to co-operate with the lug so as to lock the first or the second washer provided with the lug against rotation relative to the third washer.

Abstract: A sleeve nut includes a nut (1) and a screw like sleeve (2) screwed into that nut, thereby fixing the sleeve nut to a component (7) of e.g. an aircraft, a car or the like. Between the component (7) and the nut (1) a socle (3) is inserted having at least one upright tongue (22). This socle (3) is locked against rotation with respect to the component (7).
