Arch steel structure and installation method thereof
The invention provides an arch steel structure and an installation method thereof. The arc steel structure comprises side stand columns, a connecting chord member and a middle support, wherein the side stand columns are located at the two ends of the whole arch steel structure; the connecting chord member is arranged between the two side stand columns and comprises a lower chord member and an upper chord member, and the two ends of the lower chord member are in rigid connection with the side stand columns; the two ends of the upper chord member are fixedly connected with the upper ends of theside stand columns and/or the upper end of the middle support; and the middle support is arranged between the lower chord member and the upper chord member and comprises vertical web members and diagonal bracings. The installation method of the arch steel structure comprises the following steps of dismantling the whole arch steel structure into a plurality of individual components; setting up an assembly jig below the lower chord member, and assembling the lower chord member into two arc-shaped segmentations, and arranging a portal frame installation lifting anchorage device in the position, close to the midspan, of the lower chord member; sequentially rotating and lifting the arc-shaped segmentations, installing a middle inlaid segment of the lower chord member, and conducting adjusting and welding; and installing the vertical web members and the diagonal bracings from the ends to the midspan in sequence until installation is completed. The arch steel structure and the installation method thereof have the beneficial effect that the problem that a large-scale crane cannot stand and conduct operation on site is solved.
一种拱券钢结构及其安装方法，所述拱券钢结构包括：边立柱，位于整个拱券钢结构的两端；连接弦杆，设置于两边立柱之间，包括下弦杆和上弦杆，下弦杆的两端分别与边立柱刚性连接；上弦杆的两端与边立柱的上端和/或中部支撑的上端固连；以及中部支撑，设置于下弦杆和上弦杆之间，包括竖向腹杆和斜支撑；所述安装方法包括以下步骤：将整体分解为若干个体构件；在下弦杆下方搭设拼装胎架并将下弦杆组装成两个弧形分段；在下弦杆接近跨中位置设置门架安装提升锚具；依次旋转提升弧形分段、安装下弦杆中间嵌补段，并调整、焊接；从端部往跨中依次安装竖向腹杆、斜支撑直到安装完成。本发明的有益效果是：解决了大型吊车无法在现场站位与作业的难题。
