Abstract
An apparatus for use in clamping a structure at its edge, the structure having opposed surfaces, the apparatus comprising a stanchion, a first clamping assembly attached to the stanchion and a second clamping assembly selectively slidably moveable longitudinally along the stanchion, the second clamping assembly including a support plate extending laterally outward in a direction away from the stanchion, the support plate being positioned closely adjacent one of the opposed surfaces of the structure when the structure is clamped between the first and second clamping assemblies.
Claims23
Apparatus for use in erecting a temporary guard rail comprising:
- a stanchion;
- a first clamping assembly attached to said stanchion
- a second clamping assembly selectively, slidably moveable longitudinally along said stanchion, said second clamping assembly including a support plate extending laterally outwardly in a direction away from said stanchion, said second clamping assembly further including a first collar slidably moveable on said stanchion and a first frame attached to said first collar, said first frame including a force imparting assembly, said second clamping assembly further including a second collar slidably moveable, relative to said first collar, on said stanchion, said second collar being positioned between said first collar and said first clamping assembly, and a second frame attached to said second collar, said second frame comprising said support plate, said first and second clamping assemblies being adapted to clamp a structure therebetween when said first collar is fixedly positioned on said stanchion and said force imparting assembly applies a clamping force to said second collar;
- and
- a holder for a selectively removable post for said temporary guard rail, said holder comprising:
- a base adapted to be removably attached to said support plate;
- and
- support walls upstanding from said base and defining an upwardly opening socket for receipt of said post, which provides a generally vertically, upwardly extending rail support for attaching to a transversely extending rail.
