ABSTRACT:
A heat insulating support tool is provided for a concrete wall structure. The support tool may include a pedestal member having a through-hole extending axially through the pedestal member, a fixing rod-like member extending through the through-hole of the predestal member, and a spacing holding rod-like member embedded in the concrete wall. The fixing rod-like member may include a rotating member at a front end thereof and an enlarged head member at a rear end thereof. In addition, a connecting device may be provided for connecting one end of the spacing holding rod-like member to the fixing rod-like member so that the connection of the spacing holding rod-like member and the fixing rod-like member can be released by rotating the rotating member.
