<p><P>PROBLEM TO BE SOLVED: To lighten the field-charging operation of a vibration-controller component using a mobile crane. <P>SOLUTION: A foundation frame 1 under a separate state, a fixed frame 2, a movable frame 7, an empty frame 9 made of steel and a weight made of steel are charged at the vibration-controller installing field of an existing building 19 by using the mobile type crane. The frame 9 made of steel is mounted on the roof floor section of the existing building 19 in a reciprocative and movable manner in the biaxial directions orthogonal in a horizontal plane through the foundation frame 1, the fixed frame 2 and the movable frames 5. The weight is housed in the frame 9 made of steel, mortar 10 is filled and a movable pit 8 consisting of the frame 9 made of steel, the weight and mortar 10 and having a required mass is fabricated at a field. Consequently, a vibration controller I having the movable pit 8 in the reciprocative and movable manner in the biaxial directions orthogonal in the horizontal plane is formed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
