Construction method of large-span assembly type steel-concrete combined inner supporting system
The invention relates to the technical field of constructional engineering, in particular to a construction method of a large-span fabricated steel-concrete combined inner support system, which specifically comprises the following steps: forming a vertical first support through concrete pouring; an assembly type profile steel support is arranged at the upper end of the first support; and prestressed fish-belly sills are arranged on the side edges of the first support and the assembled profile steel support to form a combined support. The concrete support and the steel support are combined, so that the strength and rigidity requirements can be met, meanwhile, the 130m span limitation of an existing standard is broken through, the inner support span limitation is improved to 200m through the steel-concrete combined inner support, the foundation pit supporting problem under the working conditions of 173m ultra-large span and complex ultra-deep foundation pits is successfully solved, and the foundation pit supporting effect is improved. And by means of the characteristic that a large space is created through an assembly type and multi-combination rod piece stress system, convenience is provided for assembly and disassembly of components and accessories, earthwork excavation and transportation, pile foundation construction and the like, and then the construction efficiency is improved.
本发明涉及建筑工程技术领域，具体是一种大跨度装配式钢混组合内支撑体系的施工方法，具体如下：通过混凝土浇筑，形成竖向第一道支撑；在所述第一道支撑的上端设置装配式型钢支撑；在所述第一道支撑和装配式型钢支撑的侧边均设置预应力鱼腹梁，形成组合支撑。本发明通过混凝土支撑与钢支撑进行组合，使得不仅能够满足强度和刚度要求，同时突破了现有规范的130m跨度限制，并通过将钢混组合内支撑将内支撑跨度限制提高到200m，成功解决了173m超大跨度和复杂超深基坑工况下的基坑支护问题，并通过其装配式、多组合杆件受力体系营造大空间的特性，为其构配件安装、拆除和土方挖运、桩基施工等提供便利，进而加快了施工效率。
