Construction method of large-span stiff steel truss structure
The invention discloses a construction method of a large-span stiff steel truss structure. The construction method comprises the following steps: deeply designing a stiff steel structure; processing a stiffened steel structure; pre-assembling the stiffened steel structure; mounting the reinforced steel columns; mounting a reinforced concrete floor supporting system; lattice column supports are installed; positioning, hoisting and welding the truss section by section; the latticed column supports are dismantled, and stiffened steel beam formwork supports are erected; closing the stiffened steel beam template, and pouring concrete; according to the method, for the stiff steel truss with the large structure and the heavy weight, the traditional high-altitude spare part installation method is replaced with the method of truss segmented machining, temporary supporting and segmented hoisting, and effective installation of components is achieved through reasonable segmentation and pre-assembly and matched use of a latticed column supporting system; the problem that in the construction process of a large-span stiff steel truss structure, the requirement for installation precision of truss arching control and the like is high is solved, the excellent effect is achieved, the purposes of smooth structure and simple and convenient construction are truly achieved, and the high popularization value is achieved.
本发明公开了一种大跨度劲性钢桁架结构施工方法，包括以下步骤：劲钢结构深化设计；劲钢结构加工；劲钢结构预拼装；劲钢柱安装；钢筋混凝土楼板支撑体系安装；格构柱支撑安装；桁架分段定位、吊装、焊接；拆除格构柱支撑，搭设劲钢梁模板支撑；劲钢梁模板封闭，浇筑混凝土；模板拆除，本发明针对结构大、质量重的劲性钢桁架，用“桁架分段加工+临时支撑+分段吊装”方法来代替传统的高空散件安装方法，通过合理化的分段和预拼装，并配合使用格构柱支撑体系，实现构件的有效安装，解决了大跨度劲性钢桁架结构的施工中桁架起拱控制等安装精度要求高的难题，并取得了极好的效果，真正实现结构顺利、简便施工的目的，具有较高的推广价值。
