An auxiliary structure for an elevation facility of a large-sized building is provided to allow a shopping cart to smoothly convert a direction by using a guide frame. In an auxiliary structure for an elevation facility of a large-sized building, a plurality of through-holes is formed on the upper surface of a lower frame(220) constituting a guide frame(200) and is formed in an upper frame(210) installed on the upper surface of the lower frame. The upper and lower frames are engaged by bolts(260) penetrating the through-holes. A burying nut is buried under the bottom surface on which the guide frame is installed. The bolts are screw-coupled to the burying nut to fix the guide frame to the bottom surface. The ends of the upper and lower frames are bent to the outer side so that a shopping cart can be safely separated from the elevation facility or can smoothly enter the elevation facility.
