Temporary locking construction method for closure of steel box girders of pier tower girder consolidation system
The invention discloses a pier tower beam consolidation system steel box beam closure temporary locking device and a construction method, and is characterized in that the temporary locking device comprises a U rib, a steel plate, a finish rolling deformed steel bar, a nut, a top plate and a bottom plate, blanking is performed according to the distance of a closure opening and the size of a steel box beam, and the shape size of the steel plate and the length of the finish rolling deformed steel bar are determined; the temporary locking device totally needs 34 pieces of PSB1080 finish rolling deformed steel bars with the diameter being 40 mm. The construction technology comprises the steps of construction preparation, positioning and lofting, locking device steel plate welding, opposite pulling of the opposite pulling device, finish rolling deformed steel bar installation, closure opening main welding seam welding and temporary locking device dismantling. According to the device and the method, on the premise of guaranteeing the closure quality and safety of the steel box girder, the problem of quickly and accurately locking the closure opening is well solved, and the economic benefit and the social benefit are obvious; and after implementation, each index meets the design and specification requirements.
本发明公开了一种墩塔梁固结体系钢箱梁合龙临时锁定装置及施工方法，其特征在于：所述临时锁定装置包括U肋、钢板、精轧螺纹钢以及螺母和顶底板，根据合龙口距离以及钢箱梁尺寸下料，确定钢板形状尺寸以及精轧螺纹钢长度，所述临时锁定装置共需34根PSB1080的φ40mm精轧螺纹钢。施工工艺包括施工准备、定位放样、锁定装置钢板焊接、对拉装置对拉、精轧螺纹钢安装、合龙口主焊缝焊接、临时锁定装置拆除；本装置及方法在保障钢箱梁合龙质量、安全的前提下，很好地解决了快速精确锁定合龙口的问题，经济效益和社会效益明显；实施后各项指标均满足设计及规范要求。
