CONSTRUCTION METHOD OF PUSHING-OUT PART OF BASE ISOLATION BUILDING

摘要

PROBLEM TO BE SOLVED: To restrain cost by constructing a pushing-out part of a base isolation building by necessary minimum temporary construction.SOLUTION: A construction method of a pushing-out part 20 of a base isolation building 10 constructed by installing a base isolation device 40 on a foundation 2, temporarily constructs a timbering 30 for supporting a floor beam 22 of the pushing-out part 20 on the foundation 2, and constructs the pushing-out part 20 above the floor beam 22 in a state of installing a slide bearing 50 capable of absorbing earthquake motion on its timbering 30. Actually, the timbering 20 is temporarily constructed on the slide bearing 50 installed on the foundation 2. The pushing-out part 20 is also constructed by placing concrete on the floor beam 22. After constructing at least one layer of the pushing-out part 20, the timbering 30 and the slide bearing 50 are removed.
