Abstract: Safety stanchions for supporting a safety cable and the like include a tapered tubular post having a lower end for attachment to a support base at an oblique angle and an upper end for supporting the safety cable. A unique base or base assembly for mounting a stanchion upon a structural member such as an I beam is also provided. Various unique safety stanchion apparatus and methods for mounting safety stanchions to concrete floors, beams and girders and other concrete structures are also provided.

Abstract: A sliding rail anchor assembly (22) includes a pair of anchor subassemblies (23) that latch together to slidably engage the crown (29) of a “rail” (30). Each anchor subassembly (23) includes a hook engaging portion (34) and a rail engaging portion (36). The hook engaging portion carries an inboard “post” (46) and forms a hook engaging aperture (44) and an inboard post receiving aperture (40). When the anchor subassemblies (23) are properly aligned and laterally moved together so that the hook engaging portions (34) abut, each inboard post (46) is received by the post receiving aperture (40) in the other anchor subassembly (23). Each anchor subassembly (23) also includes a latch (54) which engages the “head” (60) of the opposing inboard post (46) extending through the post receiving aperture (40). When a safety hook (24) engages hook receiving apertures (44) the latches (54) are held in their fully latched positions.

Abstract: A concrete form panel clamp includes a threaded rod having a first pin mounted at a first end generally perpendicular to the rod. A second pin spaced away from and generally parallel to the rod is slidably mounted on the rod. A nut threaded onto the rod selectively forces the second pin toward the first pin.

Abstract: An anchorage for anchoring an article to a bilateral flange which can have a width in a wide range of widths. First and second hooks are hooked over opposite flanges and securely retained thereon by a webbing strap of adjustable length extending between the two hooks. The webbing strap is permanently secured at one end to one of the hooks, and extends through a clamp on the other hook. The length of the webbing strap between the two hooks is fully adjustable in a wide range to accommodate the varying flange widths. As an alternative to a webbing strap and clamp, the hooks can be adjustably linked by an interpenetrating tongue and slot or buckle, mutually latched at a selected hook separation by a detent having projections urged into notches on the tongue.
