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. |

DETAILED DESCRIPTION It is therefore a principal object of the present invention to provide a guide jig to be used in a novel process for lifting an outer wall member in which difficulties inherent to the heretofore known processes for lifting an outer wall member of a curtain wall.
A more specific object of the present invention is to provide a guide jig for lifting an outer wall member of a curtain wall, which can guide a transporting operation of lifting an outer wall member to be mounted up to a mounting level simply and safely along guide rails without interfering with already mounted outer wall members and which enables to simply draw the outer wall member to be mounted from its lifted position close to a building body to connect it to the already mounted outer wall members.
According to one feature of the present invention, there is provided a guide jig for lifting an outer wall member of a curtain wall comprising a nearly L-shaped arm having two legs extending in two directions making a predetermined angle therebetween, first and second brackets 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 fixedly secured to the first and second brackets, respectively, a rope engaging member provided at a tip end portion of one leg of the arm, and locking means provided between the arm and one of the brackets for connecting or disconnecting the arm to or from a free end of the one bracket, whereby when the arm and the free end of the one bracket are 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.
According to another feature of the present invention,between the tip end portions of the legs of the arm and the first and second brackets, respectively, by a limited angle about axes in parallel to the first and second sliders, respectively
