ABSTRACT:
A guide jig for lifting an outer wall member of a curtain wall is constructed principally of a nearly L-shaped arm having two legs extending in two directions making a predetermined angle therebetween. First and second brackets are connected to tip end portions of the respective legs of the arm so as to be rotatable about respective axes substantially perpendicular to a plane containing the arm, first and second sliders are fixedly secured to the first and second brackets, respectively, and a rope engaging member is provided at a tip end portion of one leg of the arm. Locking means for connecting or disconnecting the arm to or from a free end of one of the brackets is provided between the arm and the one bracket, and when the arm and the free end of the one bracket is connected to each other by the locking means, the first and second sliders are held apart from each other by a predetermined distance in the direction perpendicular to a lifting plane of the outer wall member, provided that they are kept directed nearly in the vertical direction.
