The present invention relates to a device for reinforcing the shearing force and negative moment of a box-type concrete structure capable of effectively dispersing the shearing force and negative moment on a corner part of a box-type concrete structure installed in a subway, an underground way, and a waterway. The device includes a stiffening member affixed in a diagonal direction to a corner between the topside wall and side wall of a box-type concrete structure including a topside wall, side wall, and floor, dispersing the shearing force and negative moment generated from the corner, and bended to closely affix to a corner surface inclined between the topside wall and side wall; and an anchor member affixing the stiffening member to the topside wall and side wall. According to the present invention, by pressing the topside wall and side wall of the corner with the anchor member closely affixing the stiffening member to the topside wall and side wall, effectively dispersing the shearing force and negative moment applied to the corner of the box-type concrete structure, improving stability of the structure by preventing cracking, and reducing unnecessary cost in unnecessary members and in maintenance. Also, the installation is easy. |
