High-altitude large-span cantilever platform incremental launching construction system and construction method thereof
The invention discloses a high-altitude large-span cantilever platform incremental launching construction system and a construction method thereof.The construction system comprises a cantilever platform, an incremental launching sliding mechanism and an anchoring mechanism, and the cantilever platform is formed by assembling I-shaped steel main beams, sharing secondary beams, platform panels and protective railings in a span-by-span mode; i-shaped steel main beams at the inner side ends of the supporting secondary beams exceed the range of the supporting secondary beams and the platform panel and extend towards the inner side of the structural floor slab, and the gravity centers of the supporting secondary beams and the platform panel are located in the range of the structural floor slab all the time, the pushing sliding mechanism comprises sliding track beams arranged on the structural floor slab, and the tops of the sliding track beams are each provided with one I-shaped steel main beam in a sliding mode; a pushing oil cylinder is arranged between the inner side end of the sliding rail beam and the I-shaped steel main beam, and the anchoring mechanism anchors the sliding rail beam on a structural floor and clamps and fixes the I-shaped steel main beam on the top of the sliding rail beam in a sliding mode. According to the hydraulic synchronous pushing system, efficient mounting and dismounting of the cantilever platform are achieved, the assembling procedure is conducted indoors, the risk of high-altitude edge operation does not exist, and the personal safety of constructors is guaranteed.
本发明公开了一种高空大跨度悬挑平台顶推施工体系及其施工方法，施工体系包括悬挑平台、顶推滑移机构和锚固机构，悬挑平台由工字钢主梁、分担次梁、平台面板和防护栏杆分跨组拼而成，其内侧端的工字钢主梁超出分担次梁和平台面板范围并向结构楼板内侧延伸，且其重心始终位于结构楼板范围内，顶推滑移机构包括设置在结构楼板上的滑移轨道梁，滑移轨道梁顶部均滑动设置有一根工字钢主梁，且其内侧端与工字钢主梁之间设置有顶推油缸，锚固机构将滑移轨道梁锚固在结构楼板上并将工字钢主梁滑动卡固在滑移轨道梁顶部。本发明利用液压同步顶推系统实现了悬挑平台的高效安拆，拼装工序在室内进行，不存在高空临边作业的风险，保证了施工人员的人身安全。
