The invention relates to the technical field of bridge construction, and discloses a novel gate-type lifting appliance for an arch bridge steel grid beam and a lifting method.The novel gate-type lifting appliance for the arch bridge steel grid beam comprises cross beams, longitudinal beams and web stiffening plates, the cross beams comprise the first cross beam and the second cross beam, and the first cross beam and the second cross beam are arranged in parallel; web stiffening plates are arranged on the first cross beam and the second cross beam, the longitudinal beam comprises an outer longitudinal beam and an inner longitudinal beam, and the two ends of the outer longitudinal beam and the two ends of the inner longitudinal beam are fixedly connected with the first cross beam and the second cross beam respectively; the defects that a traditional grid beam lifting appliance is large in dead weight, bolt connection construction is inconvenient, and the lifting appliance cannot be installed at the junction of longitudinal and transverse beams are overcome, a lifting rod hole can pass through a door opening space in the lifting process, the length of the transverse beam of the lifting appliance and the overall steel consumption are greatly reduced, assembly and disassembly are rapid and convenient, meanwhile, structural stress is more reasonable and reliable, and the lifting appliance is convenient to use. The overall rigidity and the hoisting safety of the hoisting tool are improved, and the hoisting construction of the high-tonnage steel grid beam can be met.
本发明涉及桥梁施工技术领域,公开了一种拱桥钢格子梁新型门式吊具及其吊装方法,拱桥钢格子梁新型门式吊具包括横梁、纵梁和腹板加劲板,所述横梁包括第一横梁和第二横梁,第一横梁与第二横梁相互平行设置,所述第一横梁和第二横梁上均设置有腹板加劲板,所述纵梁包括外纵梁和内纵梁,所述外纵梁和内纵梁的两端分别与第一横梁和第二横梁固定连接;本发明解决了传统格子梁吊具自重大、螺栓连接施工不方便、无法在纵横梁交界处安装吊具等弊端,在吊装过程中吊杆孔可从其门洞空间中通过,大幅降低吊具的横梁长度和整体用钢量,安拆快速便捷,同时结构受力更合理可靠,增加了吊具的整体刚度和吊装安全性,能满足高吨位钢格子梁的吊装施工。
