Supporting point external splicing corrugated steel web I-shaped steel concrete composite beam bridge girder erection machine and beam erection method
The invention discloses a fulcrum external splicing corrugated steel web I-shaped steel concrete composite beam bridge girder erection machine and a beam erection method. The bridge girder erection machine comprises a front supporting leg, a front crane car, a rear crane car, a middle supporting point, a rear supporting point, a longitudinal guide beam and a rear support, the problem that in the erecting process of a corrugated steel web I-shaped steel-concrete composite beam of a novel structure through a bridge girder erection machine, due to the fact that outer sections of erecting supporting points of composite beam pieces are spliced, a transverse moving device of a common bridge girder erection machine cannot penetrate through the beam pieces is mainly solved. The special bridge girder erection machine has the advantages and beneficial effects that (1) the special bridge girder erection machine is modified from a common bridge girder erection machine, and the modification is simple and convenient; (2) the material consumption is low, and the risk of erecting a temporary bracket is avoided; and (3) the method is simple and easy to implement, and a complete set of technology with high applicability is provided for erection of the corrugated steel web I-shaped steel-concrete composite beam with a novel structure of the bridge.
本发明公开了一种支点外拼接波形钢腹板工字型钢砼组合梁架桥机及架梁方法；该架桥机其组成包括前支腿、前起重车、后起重车、中支点、后支点、纵导梁、后托；主要解决新型结构波形钢腹板工字型钢‑砼组合梁在利用架桥机架设过程中，由于组合梁片的架设支点外节段拼接，普通架桥机横移装置无法穿过梁片。本专利具有如下优点及有益效果：（1）此专用架桥机由普通架桥机改制，改制简单、方便；（2）此方法材料消耗小，避免了临时支架搭设的风险；（3）本方法简单易行，为桥梁新型结构波形钢腹板工字型钢混组合梁架设提供了适用性强的成套技术可资供鉴。
