ELASTIC BEARING DEVICE WITH BUILT-IN RESISTING DEVICE BETWEEN LIFTING FORCE AND HORIZONTAL FORCE

摘要

PROBLEM TO BE SOLVED: To provide an elastic bearing device having a built-in resisting device between lifting force and horizontal force, which is economical in cost.;SOLUTION: According to the structure of the elastic bearing device, metallic plates 3, 11 are opposed to each other via an interval. One of the metallic plates 3 has a central protrusion 5 protruded toward a center hole formed in the other metallic plate 11, and an elastic bearing body 7 having an elastic layer 13 is interposed between the metallic plates 3, 11. Then, an up-lifting inhibiting fitting 12 fixed to the central protrusion 5 functions to retain an outer peripheral surface of the central hole 24 formed in the metallic plate 11, and cylindrical steel shearing keys 17 are each fitted in both a recess 18 formed in the metallic plate 11 and a recess 16a formed in a bearing plate 10 fixed to the other structure. Thus, the elastic bearing device is mounted by means of bolts 19 each inserted into a bolt insertion hole formed in the bearing plate 10 coaxially with the recess 16a, a bolt insertion hole formed in the structure coaxially with the bolt insertion hole in the bearing plate 10, and the recess 18 formed in the metallic plate 11, then screwed into a female screw hole 25 formed in the metallic plate 11 coaxially with the recess 18, and fitted in the cylindrical shearing key 17.;COPYRIGHT: (C)2006,JPO&NCIPI
