Steel structure corridor integral lifting device based on self-structure bearing and construction method of steel structure corridor integral lifting device
According to the integral lifting device for the steel corridor based on the self-bearing mode, the vertical component force of the lifting reaction force is completely borne by means of the vertical uplift bearing force, a lifting support (4) is welded to an upper steel structure of a steel corridor support, and the lifting reaction force is borne by means of the bearing performance of the support and a concrete frame column below the support. The construction method of the lifting device comprises the following steps that the temporary reinforcing pieces are installed; the lifting support (4) is subjected to component blanking; the lifting bracket (4) is welded and mounted; and the spatial lateral tie rod piece (3) is welded. According to the lifting device and the construction method thereof, excessive post-reinforcement on a main body structure can be avoided, and the construction cost is saved; force is transmitted to the concrete frame column through the steel structure, horizontal counter force is prevented from being generated and transmitted, and a stress system is simple and clear; and the horizontal stability of the lifting structure is ensured by the lateral pulling rod pieces.
一种基于自身承载方式的钢连廊整体提升装置，提升反力垂直分力依靠竖向抗拔承载力完全承受，提升支架(4)焊接在钢连廊支座的上部钢结构上，依靠支座本身以及支座下的混凝土框架柱的承载性能来承受提升反力。该提升装置的施工方法，包括以下步骤：临时加固件安装；提升支架(4)构件下料；提升支架(4)焊接安装；空间侧向拉结杆件(3)焊接。该提升装置及其施工方法能够避免过多的对主体结构的后置加固，节约施工成本；通过钢结构传力至混凝土框架柱，避免产生并传递水平反力，受力体系简单清晰；侧向拉结杆件保证提升结构水平向稳定性。
