Three-limb star-shaped pedestrian landscape bridge steel beam erecting and closure construction method
The invention discloses a three-limb star-shaped pedestrian landscape bridge steel beam erecting and closure construction method. The method comprises the steps that firstly, a trestle and multiple sets of temporary supports are erected at designed positions in water; the steel beam comprises a star-shaped section used for connecting the three arch limbs and arch limb sections forming the arch limbs, the star-shaped section is hoisted to a temporary support at the designed position through a trestle and a crane, then the three arch limbs are constructed at the same time, the arch limb sections of each arch limb are hoisted from the star-shaped section to the shoreside and from the shoreside to the star-shaped section at the same time, and the arch limbs are constructed at the same time; closing the middle parts of the arch limbs; after the arch limb sections are hoisted to the temporary support, an adjuster is installed to adjust the positions of the arch limb sections to the designed positions, then the arch limb sections are welded to the star-shaped sections, and the adjacent arch limb sections are welded to each other; and after the three arch limbs are all hoisted, the three arch limbs are subjected to prestress tension arching at the same time, and then the adjustor and the temporary support are dismantled. The hoisting device has the effect of improving the hoisting precision and hoisting efficiency of the steel beam.
本申请公开了一种三肢星型人行景观桥钢梁架设及合龙施工方法，先在水中设计位置搭设栈桥和多组临时支架；钢梁包括用于连接三个拱肢的星型段以及组成拱肢的拱肢段，通过栈桥和吊车先将星型段吊装至设计位置的临时支架上，之后三个拱肢同时施工，每个拱肢均由星型段往岸边和岸边往星型段两个方向同时吊装拱肢段，并在拱肢的中部进行合龙；拱肢段吊装至临时支架上后，安装调节器调节拱肢段的位置至设计的位置，然后将拱肢段焊接至星型段，并将相邻的拱肢段相互焊接；待三个拱肢均吊装完成后，对三个拱肢同时进行预应力张拉起拱，之后拆除调节器和临时支架。本申请具有提高钢梁的吊装精和吊装效率的效果。
