要約
(EN)
Provided is a rubber-made support device such that while there exists an upward raising force counteracting function, the thickness and the width can be reduced, resulting in compactness being achieved. Cutouts (4) which extend in the bridge axis direction are provided in upper end corners of an upper end steel plate (3a) disposed on the upper end surface of a rubber laminated body (2). Upper end protrusions (7a) of side blocks (7) are provided opposite the cutouts (4), with gaps provided in-between. When an upward raising force acts, the cutouts (4) are made to abut the upper end protrusions (7a), with the result that this arrangement is made to function as an upward raising force counteracting device. Gaps (g1) formed in the direction perpendicular to the bridge axis direction, between the cutouts (4) and the upper end protrusions (7a), are set to be smaller than gaps (2g) formed in the direction perpendicular to the bridge axis direction, between those side surfaces of the rubber laminated body (2) where rubber layers (5) exist and the inner side surfaces (7c) of the side blocks (7), said side surfaces (7c) being opposite said side surfaces of the rubber laminated body (2). As a result, when a force perpendicular to the bridge axis acts, one of the cutouts (4) and one of the upper end protrusions (7a) are made to abut each other.

提供具有上举力防止功能并且能够通过减小厚度和宽度而进行小型化的橡胶支承装置。在橡胶层叠体2的上端表面所配置的上端钢板3a的上端角部设置在桥轴方向延伸的切口部4,隔有间隙地使边墩7的上端突出部7a与切口部4相对置,在作用了上举力时,通过使切口部4和上端突出部7a抵接来作为上举力防止结构而发挥功能,将切口部4和上端突出部7a之间的桥轴直角方向的间隙g1设定得比橡胶层5所在的部分的橡胶层叠体2的侧面和与该侧面相对置的边墩7的内侧面7c之间的桥轴直角方向的间隙g2小,在作用了桥轴直角方向的力时,使切口部4和上端突出部7a抵接。
