PURPOSE:To prevent the breakage of a structure by a method in which first and second slide plates are provided in order on the downside of a structure, first and second support mechanisms are provided between the second slide plate and the foundation, and a rotary spherical seat is provided to the upper end slider of the second support mechanism. CONSTITUTION:First and second slide plates 15 and 16 are provided on the downside of a structure 11, and a fixing plate 22 is provided through a support base 13 to the upper part of the foundation 12. The first support mechanisms 17 of an elastic material 21 set at an interval between the second slide plate 16 and the fixing plate 22. A guide cylinder 23 is provided on the support base 13 between the mechanisms 17, an inner cylinder 24 is slidably attached to the cylinder 23, and a slider 29 is rotatably provided on the upside of the cylinder 24. A spring 25 to give a force by which the slider 29 is pressingly contacted with the downside of the auxiliary slide plate 18 is provided in the cylinder 23. A pressing force regulating mechanism 26 is provided between the inner surface of the bottom of the cylinder 23 and the spring 25. |
