PROBLEM TO BE SOLVED: To provide a quake absorbing structure under foundation for achieving quake absorption under foundation even when the base foundation of a building is a cast-in-place foundation, and a construction method of the quake absorbing structure under foundation.SOLUTION: In a quake absorbing structure under foundation in which piece-shaped quake absorption bearing materials 4 are disposed between the ground 6 or a ground foundation 5 installed on the ground 6 and a concrete foundation 2 for supporting the building such that the adjacent quake absorption bearing materials 4 are isolated from each other, and a concrete foundation bearing plate 3 is disposed so as to be bridged between those quake absorption bearing materials 4, the concrete foundation bearing plate 3 is used as the bottom part form of the concrete foundation in the case of installing the concrete foundation. It is desired that the concrete foundation bearing plate 3 includes a support part 3c for supporting a bar arrangement 7 and a form 8. |
