PROBLEM TO BE SOLVED: To provide a method for building a steel frame into an excavated hole which enables a building tool to be disconnected from the steel frame on a ground and the steel frame to be accurately built without tilting.;SOLUTION: This building tool 10 includes a tool body 20, a guide part 21 which is attached to the lower part of the tool body 20 and guides the steel frame 1 in the axial direction of the tool body 20, and a screw reinforcement 30. The steel frame 1 is arranged in such a manner that the upper part thereof extends along the guide part 21, the screw reinforcement 30 is screwed with a nut 31 attached to the steel frame 1, and the nut 50 is screwed to the upper part of the screw reinforcement 30 to thereby connect the steel frame 1 and the building tool 10. With this configuration, the building tool 10 can be removed by merely removing the nut 50 from the screw reinforcement 30 on the ground, and since the building tool 10 comprises a guide part 21, the axes of the tool body 20 and the steel frame 1 are arranged in alignment with each other. Consequently, the steel frame can be built accurately.;COPYRIGHT: (C)2010,JPO&INPIT
