A CIRCLE ELASTIC BEARING

摘要

The present invention relates to a circular elastic bearing comprising: upper and lower plates which are made of metal or precast concrete and which have joining holes; an elastic part which includes an elastic pad formed between the upper and lower plates and a joining groove corresponding to the joining hole to be joined with the upper and lower plates and which is connected to an elastic pad by insert molding, the elastic part including an end plate having a face treating part formed at an edge of the face which is not joined with the upper and lower plates in order to prevent a damage of the elastic pad; and an auxiliary lower plate formed below the lower plate to be joined to the lower plate and having a stud bolt, thereby securing an edge distance by a change in shape, reducing material costs through a change in shape of coping, securing flexibility of displacement, enhancing durability, prevent a damage of the elastic pad and improving waterproof properties through a waterproof and damage-preventive part, and allowing a user to easily replace the lower plate through the auxiliary lower plate.
