Strut clamp

摘要

A method for applying a clamp for a construction strut that allows a pipe to be clamped to the construction strut in which the clamp has a fastener that is not exposed above the clamp curvature and in which the fastener head is easily accessible. Also the clamp has a retaining tab and a neck portion such that it can be installed by straight-in insertion at the top of a construction strut. Also, the method has an embodiment in that the clamp can be installed either on the open side of the construction strut or on the closed side using slots in the closed side by straight-in passing the retaining tab past the inturned flanges on the top of the construction strut and by a rotation at the bottom of the construction strut.

1. A method for clamping a pipe or conduit or similar circular item to a standard construction strut of the type having a top side with a longitudinal space defining an opening having a width dimension defined by spaced apart inturned flanges comprising:
providing a strut clamp comprising;
a metal strip having a first end and a second end, near the first end having a neck portion that has a width that is less than the width dimension of the longitudinal space of the standard construction strut and a retaining tab below the neck portion, the retaining tab having a first and second side each extending outwardly on opposite sides of the neck portion, and the first side having an upward facing edge and the second side having an upward extending hook the upward facing edge and the top of the hook being aligned parallel to the inturned flanges the retaining tab having a width that is less than the width dimension of the longitudinal space of the construction strut and the metal strip near the second end being adapted for passing a fastener through it and an intermediate portion extending between the first and second ends having a curvature portion; attaching the first end of the metal strip to a construction strut by passing the tab allowably by straight-in insertion through the opening whereby attaching the clamp to the construction strut can be done with the clamp aligned longitudinally of the construction strut and the hook on the second side of the retaining tab engaging an inturned flange of the construction strut either before placing a pipe or conduit or similar circular item under its curved portion or after that item is in place, placing it over the item such that the curvature engages the item; providing a nut having opposite ends defining a length dimension that is long enough to span the inturned flanges each of the ends being formed as a pair of outwardly extending spaced apart hooks each hook having an upward facing curved element and the hooks being spaced apart to define a width dimension that is less than the opening width and a central portion extending from the pairs of hooks and having a threaded hole substantially midway of the central portion the distance between the hooks being such that the hooks will engage the inturned flanges of the construction strut when the nut is placed under them; passing the nut through the opening and turning it to allow the hooks to engage under the inturned flanges of the construction strut; fixing the strut clamp in place to secure the pipe or conduit or similar circular item in place by tightening a fastener extending from the second end of the strip to the nut.
