VIBRATION DAMPING FLOOR STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a vibration damping floor structure that offers high workability and improved construction work quality.SOLUTION: A protruded engaging part (121d) is inserted into a recess (141b) when either of the protruded engaging part (121d) or the recess (141b) shifts relatively with the other in a first direction. After the protruded engaging piece (121d) is inserted, the protruded engaging part (121d) is engaged with the recess (141b) when either of the protruded engaging part (121d) or the recess (141b) shifts relatively to the other in a second direction that differs from the first direction. A bracket member (120) and a dynamic vibration absorber (140) are fixed temporarily when the protruded engaging part (121d) and the recess (141b) are engaged.SELECTED DRAWING: Figure 4C
