A fall protection restraint apparatus that is utilized during building construction comprising a base (20) that rests on the lowest floor surface of a building during construction. A number of poles (36) are connected to the base sequentially, as construction height requires, to form a structurally sound column. Support cables (40) are connected between the poles and the building under construction to horizontally support the column by forming a guyed matrix. A retractable lifeline lanyard (48) is attached to D-rings on the end cap (54) on the uppermost pole (36b), thereby allowing the lanyard to expand and retract freely until a sudden tug impedes and secures the lanyard's movement. A construction worker (50) wears a fall arrest harness (52) that is connected to the lanyard, thus providing protection. In the event of a fall, the lanyard limits and maintains the minimal distance between the worker and the column, thereby precluding a fall to the surface below.

La présente invention concerne un dispositif de retenue contre les chutes s'utilisant pendant la construction de bâtiments et dont le socle (20) repose sur le plancher inférieur du bâtiment pendant la construction. Plusieurs mâts (36) sont reliés séquentiellement au socle, au fur et à mesure des besoins en hauteur de la construction, de façon à former une colonne structurellement saine. Des haubans (40) sont passés entre les mâts et le bâtiment en cours de construction, de façon à assurer horizontalement la colonne par la réalisation d'une matrice haubanée. Une longe de sécurité rétractable (48) est maintenue à des anneaux-boucles équipant l'embout de tête de mât (54) monté sur le mât du sommet (36b). Cela permet à la longe de se déployer et se reprendre librement jusqu'à ce qu'une secousse brutale s'oppose au mouvement de la longe et le bloque. Le personnel (50) est équipé d'un harnais de sécurité (52) solidaire de la longe, ce qui assure sa protection. En cas de chute, la longe limite et conserve une distance minimale entre le personnel et la colonne, évitant ainsi la chute sur la surface inférieure.
