Segmented construction method for large-span steel beam
The invention discloses a segmented construction method for a large-span steel beam, and relates to the technical field of constructions.The method at least comprises the following steps that S10, a site is leveled, the bearing capacity of a foundation is detected, embedded parts are arranged according to construction requirements, and whether the load capacity of the foundation meets design requirements or not is determined; s20, a supporting steel structure is installed on the construction site; s30, temporary buttresses are installed at the positions, between the supporting steel structures, of segmented openings of the large-span steel beams; s40, steel beams are installed at the tops of the supporting steel structures and the temporary buttresses; the method specifically comprises the following steps that S401, a lifting appliance is used for lifting steel beams in a segmented mode, and the steel beams are assembled on temporary buttresses and a supporting steel structure; s402, welding seams between the steel beams are welded; s50, dismantling the temporary buttress; s60, the steel beam is coated with finish paint; and S70, cleaning the site. The method has the beneficial effects that the hoisting risk is reduced, and the smooth traffic is ensured.
本发明公开了一种大跨度钢梁的分段施工方法，涉及建筑技术领域，所述方法至少包括以下步骤：S10，平整场地、地基承载力检测以及按照施工要求布置预埋件，确定地基的负荷能力是否满足设计要求；S20，在施工场地上安装支撑钢结构；S30，在支撑钢结构之间的大跨度钢梁分段口处安装临时支墩；S40，在支撑钢结构与临时支墩顶部安装钢梁；具体包括以下步骤：S401，使用吊具分段吊装钢梁，使钢梁拼装在临时支墩和支撑钢结构上；S402，对钢梁之间焊缝进行焊接；S50，拆除临时支墩；S60，在钢梁上涂装面漆；S70，清理现场。本发明的有益效果：既降低了吊装风险，还保证了交通的通畅。
