Abstract

PURPOSE:To draw out a steel material by means of a jack having small strokes by a method in which a large number of fitting holes are beforehand provided in row in the longitudinal direction of a steel material penetrated into concrete, etc., and the bracket-like metal of the jack is orderly fitted into the fitting holes of the steel material. CONSTITUTION:The web portion 1a of a H-shaped steel material 1 penetrated into concrete, etc., is provided with fitting holes 2 in row at given intervals in the longitudinal direction. A bracket-like metal 3 is fitted through a bolt 4 into the fitting holes 2 of the steel material 1 in its projected portion from concrete A, and a jack 5 is inserted into between th bracket-like metal 3 and the surface of the concrete A and extended through a liner 6, etc. When the drawing amount of the steel material reaches a fixed one, the bracket-like metal piece 3 is refitted into the fitting hole 2 in the lower stage of the steel material 1 and the same operations are repeated to draw out the steel material 1.
