Building frame construction safety-barrier system and method
A cable safety-barrier system for use along an elevated region of lateral exposure in a building structure having plural, spaced, laterally next-adjacent uprights distributed along the exposure region. The system, in an operative condition, includes (a) plural cable-threading brackets distributed along the exposure region and anchored, at least one each, to each of such uprights, (b) an elongate cable having ends and a long axis, and between such ends plural elongate portions, operatively threaded as a continuum between the cable's ends through each of the brackets, and (c) adjacent each bracket, an associated securing device functionally locked to an associated, elongate portion of the cable, inhibiting any appreciable motion of the cable portion generally along the cable's long axis relative to the associated bracket.
1 . A cable safety-barrier system for use along an elevated region of lateral exposure in a building structure having plural, spaced, laterally next-adjacent uprights distributed along the exposure region, said system, in operative condition, comprising
plural cable-threading brackets distributed along the exposure region and anchored, at least one each, to each of such uprights,
an elongate cable having ends and a long axis, and between said ends plural elongate portions, operatively threaded as a continuum between its said ends through each of said brackets, and
adjacent each bracket, an associated securing device functionally locked to an associated, elongate portion of said cable, inhibiting any appreciable motion of said cable portion generally along the cable's long axis relative to the associated bracket.
2 . The system of claim 1 , wherein, relative to the mentioned region of lateral exposure, the brackets present in that region are disposed at a substantially common elevation.
3 . The system of claim 1 , wherein each securing device is releasably locked to its respective, associated cable portion.
4 . The system of claim 3 , wherein each securing device takes the form of a releasable clamp.
5 . The system of claim 3 , wherein each securing device takes the form of a wedge removeably driven between its associated, cable portion and the nearby, associated upright.
6 . The system of claim 1 , wherein said cable possesses pairs of next-adjacent, spaced reaches that extend, with respect to each pair of said reaches, in opposite directions relative to, and away from, an associated cable portion and securing device, and each bracket and associated securing device collaborate to create a structural strain-relief condition relative to the paired cable reaches that extend oppositely away from the securing device.
7 . The system of claim 6 , wherein each securing device is releasably locked to its associated cable portion.
8 . The system of claim 7 , wherein each securing device takes the form of a releasable clamp.
9 . The system of claim 7 , wherein each securing device takes the form of a wedge removeably driven between its associated cable portion and the nearby, associated upright.
10 . The system of claim 1 , wherein each bracket includes an elongate tunnel having opposite ends bracketing a generally central, open bifurcation which is included in the tunnel, said cable extends through said tunnel with one of its elongate portions being disposed within said bifurcation, and the securing device which is associated with said one elongate portion is disposed substantially non-moveably within said bifurcation.
11 . The system of claim 1 , wherein the building structure is a building frame, and the uprights take the form of columns in that frame.
