Abstract

La présente invention concerne un appareil de support de type en porte-à-faux et, plus particulièrement, un appareil de support de type en porte-à-faux pour une passerelle étendue. Dans l'appareil de support de type en porte-à-faux, une unité de fixation de base et une unité de support de plaque sont formées séparément, et l'unité de support de plaque comprenant un cadre de support et un arbre est relié à une plaque pliée dans un état dans lequel la plaque pliée qui est pliée en une forme de 'ㄱ' est fixée sur une structure de base de telle sorte que la construction peut être réalisée facilement et rapidement sans utiliser de grue, etc., et la fixation stabilisée sur la structure de base peut être éventuellement effectuée. De plus, un amortisseur est formé entre la plaque pliée et l'arbre pour absorber un moment appliqué à l'arbre, et ainsi, une plaque de pont peut être supportée de façon stable.
