METHOD FOR PULLING UP EQUALLY THE UPPER STRUCTURE OF A BRIDGE USING A RAISING BRACKET SUPPORTING LOAD DISPERSEDLY, HAVING A DISPLACEMENT MEASURING INSTRUMENT

摘要

The present invention is to install a displacement measuring device to raise the bridge upper structure with a balance when lifting the upper structure, including the bridge girders in order to increase the reinforcement of the bridge and to secure the space of the bridge more wide, Bridge top structure with a displacement measuring device to distribute the load.;The bridge upper structure load-distributing support raising brackets are provided with vertical support plates of a predetermined length, weld front and rear horizontal support plates are welded on both sides of the vertical support plate at a predetermined height away from each other, and both side surfaces of the front and rear horizontal support plates. Hydraulic triangular front and rear upper triangular supports are installed in the upper and lower triangular supports at regular intervals, and at least a plurality of steel bar supports are installed, and the hydraulic jack support horizontal beam and displacement jack are installed at the lower part of the rear horizontal support plate. The lower triangular support that installs the low beam and can support them in the lower part is welded to the lower part of the vertical support plate,;Or, install a vertical support plate of a constant length, and install a trapezoidal trapezoidal steel bar support on the upper portion of the vertical support plate at a predetermined distance to the trapezoidal steel bar support after installing a plurality of steel bar support at the bottom of the rear horizontal support plate Hydraulic jack support horizontal beam with hydraulic jack support horizontal beam and displacement measuring device is installed and the lower triangular support that can support them in the lower part is welded and installed in the lower part of vertical support plate.;After installing a plurality of load-bearing load-bearing support brackets on both sides of both sides of the bridge coping part, and connecting the upper connection fixed steel rods installed through the steel rod support of the bridge-bearing load-bearing support brackets, respectively. The upper portion of the bridge upper structure load-distributing support lift brackets are interconnected at the upper part of the bridge coping portion by fixing with nuts to the steel rod support, and the lower triangular supports of adjacent upper portion of the bridge upper structure load-distributing support lift brackets are flexurally reinforced lower connecting steel bars. After the interconnection, install the hydraulic jack support horizontal beam on the lower triangular support, install the displacement measuring device, install the hydraulic jack support horizontal beam on it, install the hydraulic jack on the rear horizontal support plate, and then equip the upper structure on it. The upper structure after the support H beam is installed in close contact with the bottom of the girder After the displacement measuring device is installed on the water equality support H beam, the hydraulic jack is gradually introduced while the lifting force is gradually introduced to the hydraulic jack, and then the repair work on the bridge or the height of the bridge is increased to increase the geometry space of the bridge.
