An integral elastomeric bearing is provided to support a bridge stably, to increase durability and to cut down on the price by forming wedge contact parts on an upper plate to function as an upper wedge and reducing the horizontal, vertical and longitudinal size of a product, to shorten a construction progress and to decrease human power and production costs by manufacturing upper and lower plates required for a movable end and a fixed end equally, and to prevent the breakage of a rubber pad against shear deformation and to make maintenance work easy. The integral elastomeric bearing(50) comprises an upper plate(10) contacted with a bridge deck and provided with many rubber pad joints to couple with rubber pads and C-shaped wedge contact parts to function as an upper edge, a lower plate(20) integrated with a rubber pad and provided with C-shaped wedge joints, and a wedge portion(30) provided with primary and secondary wedges to couple with the wedge joints of the lower plate by coupling members and to make contact with the wedge contact parts of the upper plate. Hereon the width of the wedge contact part of the upper plate is formed to be larger or same as the width of the wedge joint of the lower plate to form a movable end or a fixed end easily, and the width of the primary and secondary wedges are manufactured in the same width of the lower plate and the height of the primary and secondary wedges are manufactured to make contact with the wedge contact parts of the upper plate sufficiently while being coupled with the wedge joints of the lower plate. |
