Fastener Installation Tool for Roof Truss Framing and Construction System

摘要

An installation tool for fastening a top plate to a roof support member and other structural connections is adapted to drive threaded fasteners at a pre-established angle. The tool preferably includes a rotary driver assembly and a telescopic tube assembly. A guide head assembly is mounted adjacent the outer end of the telescopic tube assembly. Locating structures function to properly precisely set the drive angle of the fastener. Spaced stabbers prevent the fastener from moving during the installation. A releasable lock mechanism locks the guide head assembly to the end of the telescopic tube assembly. The guide head assembly has a floating guide to align the fastener head with a drive bit, and a wear sleeve for centering and aligning the fastener screws. A spacer collar is dimensioned to set a pre-established penetration depth for the fastener. An automatic release trigger locks the telescopic tube assembly and imposes a pre-established stabbing force threshold prior to driving the fastener and allowing the tubes to telescope.

主权项

1. An installation tool for fastening a first member to a second member comprising:
a driver assembly comprising an elongated telescopic tube assembly having a proximal end and a distal end, a driver which generates torque mounted adjacent said proximal end and a torque transfer unit disposed in said tube assembly for transferring torque produced by said driver to a fastener coupler adjacent said distal end; and a guide head assembly mounted adjacent said distal end and having a locating end and a non-coplanar locating surface and a fastener channel defining an axis disposed at an angle θ to said locating surface and configured to receive a fastener so that when said locating surface is positioned against said first member, said locating end is positioned adjacent said second member, said fastener is received in said channel, and said driver is powered, said fastener coupler engages said fastener and is torqued to drive said fastener through said first member at said angle θ into said second member.
