Apparatus for adjusting position and maintaining function according to lifting the upper structure of bridge, and construction method for lifting up the upper structure

摘要

The present invention mounted on a conventional T Chair tooth shape by adjusting its position when all kinds of the bridge superstructure of the girder is used for curved parts of pieces gradient gateun slab and normal bridge beyond the location binary appointed on the pier and alternating or as by mounting the binary appointed position after the maintenance of the device gyojwa relates to a construction method using the position adjusting function and a holding apparatus according to an impression of the bridge superstructure to prevent the said girder nakgyo to implement such operation,; Fixing the bracket to the support perpendicular to the alternating long side of the girder lower if the shift install the position adjustment and the function holding unit to the anchor bolt and provided on the bracket wherein the vertical support to the vertical direction yuapjaek between the girder and the vertical support bracket and the securely fixed to the vertical reaction force against and install the sliding buffer pad to the girder side in the opposite direction to that installation over the horizontal support in the long side of the shift to move the bridge superstructure to the horizontal support subject on the entire surface of one side of the vertical support bracket and in the horizontal direction yuapjaek reaction force against the said installation in a horizontal direction yuapjaek on the stand is installed on the horizontal yuapjaek reaction for between one side of the vertical supporting bracket and the horizontal direction yuapjaek while installed horizontally yuapjaek reaction force against the lower portion of the horizontal support the sliding between the lower surface of the upper part and the horizontal support By installing the inner plate installed a sliding cushion pad therebetween, and then using the bridge superstructure moves the steel bar horizontally yuapjaek reaction force against the installed adjacent to the anchorage provided on the outermost surface of the shift of the direction in which secures the fixing,; The position adjustment and the function holding unit connected to each other when installing on a pier while the vertical supporting installation secure the bracket to anchor bolts on both sides of the pier long side of the girder the lower the connection rod and the vertical support bracket is installed on the other side of the fixed and girders and the while mounted on the vertical support bracket in a vertical direction yuapjaek and install over the horizontal support in the long sides of the pier on the entire surface of one side of the vertical supporting brackets between the vertical support bracket in the opposite direction to move the bridge superstructure of that installation the sliding buffer pad to the girder side and a fixed installation a vertical reaction force against the horizontal support target and installing horizontally yuapjaek reaction force against the lower portion of the horizontal support one side of the horizontal direction yuapjaek reaction force against the said vertical support bracket horizontally on the stand is installed on the horizontal direction against the reaction force between yuapjaek Direction while yuapjaek install and install the sliding guide plate between the lower surface of the upper part and the horizontal support in the horizontal direction yuapjaek installed a sliding cushion pad therebetween, and then are installed on the outermost surface of the bridge direction in which the upper structure is moved pier anchorage the adjacent horizontal yuapjaek reaction force against the installed with a fixed fixing install the positioning and the function holding apparatus using a steel rod and then by operating the vertical direction yuapjaek upwardly bridge one the upper structure of the girder a distance increase from gyojwa device following and it is to release the oil pressure at a planned distance moved by the progress to be moved a predetermined distance raise the girders by using the horizontal direction, and then the yuapjaek yuapjaek seating of the girder bridge superstructure on gyojwa device.
