Abstract

PROBLEM TO BE SOLVED: To cause a joint plate to follow oscillating movement of an earthquake by a method wherein two end parts are rotatably attached to a pair of fixed metals and a pivotal support pin at the portion of a central part is provided with two or more pantographform central maintaining links to which a joint plate is attached. SOLUTION: In a central maintenance link 14, two end parts are rotatably attached to fixed metal fittings 8 and 8 by means of pivotal support pins 23 and 23 and pivotal pins 12 at the portion of a central part in which at least two or more square shapes are formed are rotatably attached to an attaching tool 13 of a joint plate. Next, when buildings 2 and 2 are longitudinally and laterally oscillated due to an earthquake, a plate 11 is always held at the central part of a joint part 3 by means of two links 14, and the plate 11 is slid between support beds 9 and 9 and press plates 16 and 16 to absorb oscillation movement. Two links 14 are vertically rotated following vertical oscillation movement at some degree of the buildings 2 and 2, and the two end parts of the plate 11 absorbs a play between the support beds 9 and 9 and the press plates 16 and 16.
