High-altitude support-free installation method for large-span overweight box type steel beam
A large-span overweight box type steel beam high-altitude support-free installation method comprises the following steps that a large-span steel beam is divided into a plurality of sections to form steel beam sections, and the number of the sections is not less than three; two of the steel beam sections are fixedly connected with a secondary beam to form a combined hoisting unit; the combined hoisting unit is hoisted to a first preset position, and the combined hoisting unit is fixedly connected with a corresponding pipe column and a core tube embedded part; and the remaining steel beam sections are sequentially hoisted to the second preset position to be fixedly connected with the steel beam sections hoisted to the first preset position. According to the high-altitude support-free installation method for the large-span overweight box type steel beam, the large-span steel beam is subjected to segmented treatment, so that segmented hoisting is carried out, high-performance hoisting equipment is not needed, a supporting jig frame does not need to be built, and the overall construction efficiency and construction safety are improved to a great extent.
一种大跨度超重箱型钢梁高空无支承安装方法，该安装方法包括如下步骤：将大跨度钢梁分割为若干段，以形成钢梁段，其中，分段数为不少于三段；将其中两段所述钢梁段与次梁进行连接固定，以形成组合吊装单元；将所述组合吊装单元吊升到第一预设位置处，将所述组合吊装单元分别与对应的管柱及核心筒埋件连接固定；将剩余的所述钢梁段依次吊升到第二预设位置处与吊升到第一预设位置处的钢梁段进行固定连接。该大跨度超重箱型钢梁高空无支承安装方法，通过将大跨度钢梁进行分段处理，从而进行分段吊升，无需高性能的起重设备，且无需搭建支承胎架，整体的施工效率和施工安全性都在很大程度上得到提高。
