摘要: The invention presents an easy to use anchor for safety cables which can be attached the framing of floor as it is built, and removed re-used after completed. has lower upper plates separated by a spacer thickness I-beam cross-plate. clamps between two adjacent beams, with sliding around top plate being fastened firmly setscrews in plate. Eye bolts screw into provide tie-off spot cables. over deck support beams such that flush surface plywood decking concrete will poured. In use, slid desired location I-beams screwed tightly place using anchor. When laid, notched plate, forms deck. workers tie off their eyebolts time comes pour floor, are holes covered duct tape. poured, when cures removed, anchors easily detached from re-used.
