Seismic reinforcement shear key with fine adjustment to prevent damage of superstructure
The present invention relates to a shear key which enhances coupling of a bridge with an upper beam of the bridge. The present invention relates to a seismic strengthening shear key installation method which can compensate for insufficient horizontal force of a bridge support in bridges in an event of an earthquake, can be fine-tuned when installing the shear key which prevents the upper beam from falling, and combines with the shear keys without puncturing the upper beam to prevent durability degradation of a structure of the upper beam.
본 발명은 교량의 상부빔과 교각의 결합을 강화하는 전단키에 관한 것으로서, 지진발생시 교량에서 교량받침의 부족한 허용 수평력을 보완할 수 있고, 상부빔의 낙교를 방지해주는 전단키를 설치할 때 미세조정이 가능하고, 상부빔에 천공 없이도 전단키와 결합하여 상부빔의 구조물의 내구성 저하를 방지하는 지진보강 전단키 설치공법에 관한 것이다.
