Machining and assembling technology for special-shaped decorative steel arch shell of steel box girder
The invention relates to a machining and assembling technology for a special-shaped decorative steel arch shell of a steel box girder. The machining and assembling technology is characterized by specifically comprising the following steps that S1, the steel arch shell is divided; s2, machining of the parts; s3, the unit pieces are machined; s4, splicing and welding the steel arch shell; s5, pre-assembling the steel arch shell; according to the method, the left steel arched girder and the right steel arched girder are assembled in sequence, and two longitudinally-divided end segments of the left steel arched girder are disassembled from a pre-assembled structure and transported to a hoisting position to be installed; the step is repeated for three rounds, and in the fourth round, a first section in the middle of the longitudinal beam of the right steel arched beam is started to be installed; five rounds of assembly are carried out in total, and after the left steel arched girder is assembled, the right steel arched girder starts to be installed for the third round; according to the staggered construction mode, compared with symmetrical construction, a pre-assembly jig frame can be shared, it is guaranteed that the left steel arched beam and the right steel arched beam are subjected to pre-assembly operation before hoisting, and the assembly efficiency is greatly improved.
本发明涉及一种钢箱梁异型装饰钢拱壳加工装配工艺，其特征在于：具体包括如下步骤：S1：钢拱壳的划分；S2：零部件的加工；S3：单元件的加工；S4：钢拱壳的拼焊；S5：钢拱壳的预拼装；本发明中左、右两幅的钢拱梁采用先后拼装的方式，先将左副的钢拱梁两个的纵向划分的端部节段从预拼装结构上拆下，运输至吊装位置安装；重复此步骤三轮，在第四轮的时候，开始安装右幅钢拱梁的纵梁中部的第一节段；总共五轮拼装，在左幅钢拱梁拼装完成后，右幅钢拱梁开始安装第三轮；这种错位施工的方式，相比于对称施工可以共用一个预拼装的胎架，且保证了在吊装之前左右幅的钢拱梁都进行了预拼装操作，且极大的提高了装配效率。
