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.

The invention provides a novel method for manufacturing a heat insulating sash bar for window frame constructed with two oppositely positioned metal-made face members, one facing inside of the room and the other facing outside of the room, connected together only with a connecting member of a heat insulating material and not with any metal-made part to ensure heat insulation between the two face members. According to the method, the heat insulating connecting member is first inserted into the groove-like channel of a metal-made bar material having an approximately H-wise or U-shaped cross section composed of the two face members connected with a connecting part, the heat insulating connecting member is then securely fixed to the face members by caulking, the connecting part with which the face members have been integrally connected is longitudinally at least partly removed over whole length thereof to thermally isolate the face members from each other, and finally the remaining groove-like channel is filled, for example, with a pourable heat insulating material to be cured or solidified in situ.
