DEVICE FOR REINFORCING SHEARING FORCE AND NEGATIVE MOMENT OF BOX TYPED CONCRETE STRUCTURE WITH EXTENDED PASSAGE

摘要

The present invention relates to a device for reinforcing shearing force and negative moment of a box-type concrete structure capable of dispersing the shearing for and negative moment to a side wall and a corner of a box-type concrete structure installed at a subway, an underground road way, and a waterway. A stiffening member is affixed to a corner in a diagonal direction between a topside wall and a side wall in a box-type concrete structure including a topside wall, a side wall, and a floor to disperse the shearing force and negative moment generated from the corner by pressing the topside wall and the side wall. The stiffening member is installed near a corner side of the box-type concrete structure and capable of having an additional passage in the corner. According to the present invention, a stiffening member of a box-type concrete structure is installed near a corner side of the box-type concrete structure, the shearing force and negative moment to a side wall and corner of the box-type concrete structure can be effectively dispersed. Thus, cracking is prevented. The stability of the structure is increased. Additional space in the corner for vehicle or installation of a facility can be secured. The cost in installation of unnecessary members and in maintenance is reduced. The installation is easy, increasing the workability.
