Urban viaduct prefabricated segmental beam portal crane cantilever assembling method
The invention relates to an urban viaduct prefabricated segmental beam portal crane cantilever assembling method. The method comprises the steps that S1, temporary supporting frames are erected at allmiddle piers and side piers; S2, a first middle pier section beam is placed on a supporting frame at the middle pier through hoisting equipment and adjusted in place, and the first middle pier section beam and a middle pier zero block are fixed; S3, the hoisting equipment is used for symmetrically hoisting a second middle pier section beam at the middle pier, and tensioning and fixing of the second middle pier section beam are conducted; S4, the third step is circulated, and a third middle pier section beam to a sixth middle pier section beam are sequentially and symmetrically hoisted throughthe hoisting equipment; S5, a first side pier section beam is placed on the supporting frame at the side pier through the hoisting equipment and adjusted in place; S6, a second side pier section beamto a sixth side pier section beam are hoisted to the supporting frame at the side pier in sequence through the hoisting equipment; and S7, a midspan closure section between the side pier and the middle pier is poured. According to the invention, a large amount of labor is saved, meanwhile, a large amount of time is saved, and the construction period is shortened.
本发明涉及城市高架桥预制节段梁门式起重机悬臂拼装方法，包括S1：在各中墩以及边墩处搭设临时支撑架；S2：用吊装设备将中墩一号节段梁摆放在中墩处的支撑架上并调整到位，进行中墩一号节段梁与中墩零号块之间的固定；S3：用吊装设备在中墩处对称吊装中墩二号节段梁，并进行中墩二号节段梁的张拉固定；S4：循环第三步，用吊装设备依次对称吊装中墩三号节段梁至中墩六号节段梁；S5：用吊装设备将边墩一号节段梁摆放在边墩处的支撑架上并调整到位；S6：用吊装设备依次将边墩二号节段梁至边墩六号节段梁吊装至边墩处支撑架上；S7：浇筑边墩和中墩间的跨中合拢段；本发明节省了大量的人工，同时也节省了大量的时间，缩短了施工周期。
