Abstract
A temporary railing for a boundary of a building floor may include a plurality of temporary cable supports spaced along the boundary of the building floor, a plurality of vertically spaced apart cables carried by the temporary cable supports, and an access opening assembly for permitting temporary establishment of an access opening through each of the cables. The access opening assembly may include a cable jack selectively coupled in line with a respective cable and movable between a released position and a closed position, and at least one cable clamp selectively clamped to the respective cable to maintain tension beyond the access opening when the cable jack is in the released position.
Claims32
A temporary railing for a boundary of a building floor comprising:
- a plurality of temporary cable supports spaced along the boundary of the building floor;
- a plurality of vertically spaced apart cables carried by said temporary cable supports to extend along the boundary of the building floor;
- an access opening assembly for permitting temporary establishment of an access opening through each of said cables and comprising
- a cable jack selectively coupled in line with a respective cable and movable between a released position and a closed position, and
- at least one cable clamp selectively clamped to the respective cable to maintain tension beyond the access opening when said cable jack is in the released position.
A temporary railing for a boundary of a building floor comprising:
- a plurality of temporary cable supports spaced along the boundary of the building floor;
- a plurality of vertically spaced apart cables carried by said temporary cable supports to extend along the boundary of the building floor;
- an access opening assembly for permitting temporary establishment of an access opening through each of said cables and comprising
- a cable jack selectively coupled in line with a respective cable and movable between a released position and a closed position,
- at least one cable clamp selectively clamped to the respective cable to maintain tension beyond the access opening when said cable jack is in the released position,
- an openable link selectively coupled in line with the respective cable adjacent said cable jack, and
- a cable jack lock to lock said cable jack in the closed position.
A temporary railing for a boundary of a building floor comprising:
- a plurality of temporary cable supports spaced along the boundary of the building floor;
- a plurality of vertically spaced apart cables carried by said temporary cable supports to extend along the boundary of the building floor;
- an access opening assembly for permitting temporary establishment of an access opening through each of said cables and comprising
- a cable jack selectively coupled in line with a respective cable and movable between a released position and a closed position,
- at least one cable clamp selectively clamped to the respective cable to maintain tension beyond the access opening when said cable jack is in the released position,
- said at least one cable clamp comprising a primary cable clamp and a back-up cable clamp to be coupled to the respective cable adjacent said primary cable clamp, and
- an openable link selectively coupled in line with the respective cable adjacent said cable jack.
A method for permitting temporary establishment of an access opening through each of a plurality of vertically spaced apart cables carried by temporary cable supports spaced along a boundary of a building floor, the method comprising:
- selectively coupling a cable jack in line with a respective cable and movable between a released position and a closed position;
- and
- selectively clamping at least one cable clamp to the respective cable to maintain tension beyond the access opening when said cable jack is in the released position.
