DEVICE FOR REINFORCING SHEARING FORCE AND NEGATIVE MOMENT OF CONCRETE STRUCTURE WITH BOX TYPE INCLUDING STEAL BEAM

摘要

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 side wall and corner of a box-type concrete structure installed in a subway, an underground way, and a waterway. A stiffening member is installed in a diagonal direction at a corner between the topside wall and side wall in the box-type concrete structure including side walls and a floor. By pressing the topside wall and side wall, the shearing force and negative moment generated from the corner are dispersed. A rigid bead is installed along the length direction of the box-type concrete structure on the topside wall and side wall of the corner. A plurality of the stiffening members is connected to and installed in the stiffening member. By connecting and installing a shearing force and negative moment stiffening member to and in the rigid beam installed along the length direction in the corner topside wall and side wall of the box-type concrete structure, an enough pressing force can be applied to the topside wall and side wall of the corner through the rigid beam having a large contact surface, effectively dispersing the shearing force and negative moment applied to the side wall and corner of the box-type concrete structure and preventing cracking. Thus, the stability of the structure is improved; it is economic since the installation area is minimized, reducing the installation and maintenance cost of unnecessary members.
