Large-span arc-shaped steel structure without support in middle and construction method
The invention provides a large-span arc-shaped steel structure without a support in the middle and a construction method. The arc-shaped steel structure comprises an installation support, at least two arc-shaped steel bodies, a rail set and rolling mechanisms, the arc-shaped steel bodies and the rail set are fixedly installed on the installation support, the two ends of each arc-shaped steel body are each connected with one rolling mechanism, and the rolling mechanisms are arranged on the rail set in a sliding mode. The construction method comprises the following steps that S1, the rolling mechanisms are installed at the two ends of each arc-shaped steel body correspondingly; s2, the first arc-shaped steel body is hoisted to the mounting support, and at the moment, rolling mechanisms at the two ends of the first arc-shaped steel body are both in sliding connection with the track sets; s3, the first arc-shaped steel body is driven to move towards the preset construction position; and S4, the step S2 and the step S3 are circulated so that the multiple arc-shaped steel bodies can be hoisted and moved in sequence. In the application, the hoisting position of the arc-shaped steel body relative to the mounting bracket does not need to be adjusted by continuously adjusting the angle of the large hoisting equipment, so that the construction difficulty can be reduced, and the construction precision and the construction efficiency can be improved.
本申请提供了一种中部无支撑的大跨度弧形钢结构及施工方法。弧形钢结构包括安装支架、至少两个弧形钢本体、轨道组和滚动机构，各弧形钢本体和轨道组均固装于安装支架，各弧形钢本体的两端分别连接有一滚动机构，各滚动机构均滑设于轨道组。施工方法包括如下步骤：S1：在各弧形钢本体的两端分别安装一滚动机构；S2：将第一个弧形钢本体吊装于安装支架，此时，第一个弧形钢本体两端的滚动机构均与轨道组滑接；S3：驱动第一个弧形钢本体向预设施工位置移动；S4：循环S2和S3，以依次吊装和移动多个弧形钢本体。本申请中，不需要通过不断地调整大型吊装设备的角度以调整弧形钢本体相对于安装支架的吊装位置，能降低施工难度，提高施工精度和施工效率。
