Abstract

A simple but effective fastening means is provided for anchoring reinforcing expansion baskets to a concrete treated base or to a black asphalt mix during highway construction. A novel clip has a flat horizontal leg adapted to rest against the base material and has an upstanding leg at the inner end of the horizontal leg, and a downwardly turned hook at the upper end of the vertical leg which is adapted to fit snugly over the top of a horizontal rod of the expansion basket which is normally held by vertical members of the basket at a predetermined height above the base. The clips are placed along the lower horizontal rod of the reinforcing basket and then a drive pin is driven through the horizontal leg into the base using a powder actuated firing tool.

Claims

1. Means for securing a concrete reinforcing basket to a base of concrete or black asphalt or the like, wherein said basket comprises a rigidly connected assembly of spaced wires or rods including vertical spacers extending a predetermined spaced distance below said rods;

said securing means comprising a plurality of spaced metal clips, each clip having a planar horizontal leg adapted to rest on said base and an integral upstanding leg at the laterally inner end of said horizontal leg and an integral hook inwardly extending at the upper end of said upstanding leg and having a downwardly opening bight of a size to snugly embrace a rod of said basket with the top of said bight at approximately said predetermined distance from the under side of said horizontal leg, said horizontal leg being rectangular and the outer corners being turned up slightly in position to engage snugly a low velocity tool driving said pin, there being a hole through said horizontal leg concentric with said outer corners, said horizontal leg being long enough to receive the muzzle of a high velocity powder actuated gun between said hole and said upstanding leg, and adapted to receive a pin fastener means for securing said horizontal leg to said base.
