Abstract
A clamp assembly adapted for efficient assembly and disassembly of scaffolding includes a pair of pivotally coupled rotating clamp members and a wedge employed to temporarily hold the two clamp members in a closed position about a scaffolding pipe. One of the clamp members has a flange, and the clamp assembly includes a clevis coupled to a first scaffolding pipe with the clamp fitting around a second scaffolding pipe. The flange is received in the clevis, and the wedge fits through slots formed in the flange and the clevis to securely couple the first and second scaffolding pipes.
Claims17
A scaffolding clamp assembly for coupling scaffolding pipes comprising:
- (a) a first clamp member having (i) a first c-shaped jaw comprising a concave inside surface, a convex outside surface, a first end, and a second end, (ii) a first flange, and (iii) an elongate slot having a first slot portion extending through a portion of the first flange;
- (b) a second clamp member, said second clamp member comprising an arm and a concave engagement surface, the arm adapted to reside within the elongate slot, said second clamp member pivotally coupled to the first clamp member and adapted for rotation relative to the first clamp member between an open position and a closed position;
- (c) a first clevis, the first clevis adapted to be coupled to a first horizontal pipe, wherein the first clevis comprises a pair of arms and defining a first channel extending through the first clevis, wherein said first flange is adapted to be inserted between the arms of the first clevis such that the first slot portion is aligned with the first channel extending through the first clevis;
- and
- (d) a wedge adapted to be inserted into the first slot portion to hold the second clamp member in the closed position around a second horizontal pipe that is received between the first clamp member and the second clamp member, and thereby locking the first flange to the first clevis.
