摘要： PROBLEM TO BE SOLVED: To adjust the widening of a joint gap when a girder or a beam is laid between base columns adjacent to each other during the work of the erection of the girder or the beam in an iron bridge, an expressway, a viaduct or the like.
SOLUTION: A jack body (4) is installed in each of edges (2
1 ) of the upper ends (2) of the base columns (1) adjacent to each other; a base (40) of the jack body is provided with a movable plate (41) which makes protruding/receding motion; a cylinder (42) with a guide roller (43) is fixed to the movable plate; and a rod base end (44
1 ) of a piston (44) mounted to the cylinder (42) is supported on the reaction bracket (46) of the base. A girder material or a beam material (3) which is suspended above a section between the edges (2
1 ) at upper ends of both the base columns is lowered to get close to the edges (2
1 ) of the upper ends of both the base columns. In this case, in a state that the guide roller for the cylinder, imparting an advancing action to a piston rod brought into contact with the reaction bracket in a state of being positioned between the guide rollers of the pre-receding jack body, is brought into contact with both longitudinal end surfaces (3
1 ) of the girder material or the beam material and adjusted to advance and recede. Erection is established by fitting the girder material or the beam material (3) while maintaining a small gap (g) between the edge portions (2
1 ) at the upper end of the base column.
