| titleOfInvention | Apparatus for decreasing section force installed between girders in plate girder bridge for reduction of bending moment stress and introduction of re-tension force |
| abstract | The present invention, in the plate girder bridge, the reduction of the parent moment installed by connecting a certain length of both girders that can reduce the size of the bending moment, that is, the minor moment acting on the plate girders mounted longitudinally in the continuous point portion It is possible to reduce the size of the bending moment acting on the center of the plate girder mounted between the device and the ground, and to add additional tension when there is a need to introduce additional tension due to the reduced load capacity of the bridge. A cross-sectional force reduction device consisting of an upward force introduction device that introduces an upward force into the girder by introducing a tension force into the strands installed respectively connected to a plurality of saddle combined auxiliary tension brackets installed at a certain interval at a lower distance from the owner's bracket installed at the top. Cross section force acting on the plate girder bridge To reduce the mold and reinforce the load capacity,n n n In the upper part of the girder between the plate girder and the girder between the plate girder and the girder installed in the longitudinal direction, the upper part of the pier which is the continuous point portion, the plurality of unit box-shaped plate installed in the inner space at regular intervals It is installed in contact with the upper plate to extend a certain distance from the point where the inner side of the plate and the inner side of the abdomen cross each other to form a connection with another unit box-shaped plate installed inside the adjacent plate girder and weld or bolt the steel plate on the upper and lower parts of the connection. While the joints are fixed to the unit box-shaped plate and slab using anchor bolts, the space inside the unit box-shaped plate is tightly filled with foamed urethane and the gap between the upper part of the unit box-type plate and the bottom of the slab is epoxy. By After filling, the adjacent bottom plate of the unit plate girder and the longitudinally installed longitudinal ribs and stud bolts installed in the longitudinal direction on the inner part of the abdomen are provided with a plurality of unit box-shaped plates provided in the inner space at regular intervals, close to the upper side of the lower plate. The steel plate is installed in the upper and lower portions of the connection with the other unit box-shaped plate installed by welding and bolted connection to the lower flange while connecting or welded or bolted, the one side of the abdomen the steel plate is installed on the inner side of the unit box-shaped plate After installing each of the "L" section steel bolts and welded steel plate inside the "L" section steel, while the steel plate is installed on the upper and lower parts of the lower flange and connected by bolting, then the lightweight part of the space of the unit box-shaped plate Or filling with foamed urethane In the upper and lower portions of the unit box-shaped plate installed on the upper and lower sides of the upper and lower flanges, a plurality of anchorages are installed, and then a parent moment reduction device braced in X-shape while being connected to each other and fixed by connecting steel rods is installed vertically and horizontally adjacent to the continuous point. Install the plate girders at a certain distance from each other,n n n One side of the unit box-type bracket is welded to each of the upper end portions of both sides of the unit plate girder installed adjacent to the horizontally, and the bolts or welded joints are placed on the upper and lower portions of the connection portions where the unit box-type brackets meet each other. The host bracket is installed outside the inside, and the host bracket is provided with a plurality of anchorages. The box flange is provided with a plurality of box-shaped brackets installed at regular intervals in the center of the lower flange of the adjacent unit plate girder. After connecting to the lower part of the box-shaped bracket, the mounting brackets are installed on both sides of the outer side of the box-shaped bracket, and at regular intervals inside, one side of the fan-shaped bracket is attached to one side of the box-shaped bracket, and the groove is formed on the flat surface. Formed support After installing the saddle combined saddle bracket, the lower part of the plate girder is mounted on the anchorage of the host bracket bracket installed on both sides of the unit plate girder and the saddle of the saddle combined saddle bracket installed on the bottom of the girder. The saddle is installed in the anchorage bracket installed in the saddle combined supporter bracket installed at regular intervals in the center, and then the tension is introduced and fixed to the steel rod of the parent reduction device. Introduce and fix the tension force to the strand wire installed in the combined auxiliary tension bracket to install the cross-sectional force reduction device to introduce the tension force to increase the load capacity of the plate girder bridge. |
