Outward-cantilever independent large-cantilever steel corridor provided with prestressed beam plates
The invention discloses an outward-cantilever independent large-cantilever steel corridor provided with prestressed beam plates. The large-cantilever steel corridor is manufactured through the following specific implementation steps of (1) construction preparation; (2) in-place placing of section steel columns; (3) arrangement of linear prestressed tendons; (4) pouring and tamping of steel reinforced column concrete and prestressed beam concrete; (5) pre-stress tensioning and anchoring; (6) bonded prestress grouting; (7) anchorage device plugging protection; (8) corridor mounting; (9) steel corridor temporary support graded unloading; (10) post-cast strip concrete pouring; and (11) structure detection in construction and use stages. According to the outward-cantilever independent large-cantilever steel corridor provided with prestressed beam plates, the index requirements for quality control of structural cracks, deformation, deflection and the like can be met, and the construction technological process is advanced, economical and reasonable; and the method is suitable for installation of the outer cantilever independent type single-layer or multi-layer large-cantilever steel structure corridor and quality control of construction of steel reinforced concrete, bonded prestressed steel reinforced beams and no-bonded-prestress beam slab concrete applied to local parts of a concrete tower of the outward-cantilever independent type single-layer or multi-layer large-cantilever steel structure corridor.
本发明公开了一种设有预应力梁板的外挑独立式大悬臂钢连廊,该大悬臂钢连廊包含以下具体实施步骤:(1)施工准备;(2)型钢柱就位;(3)直线型预应力筋布设;(4)钢骨柱砼及预应力梁砼浇捣;(5)预应力张拉锚固;(6)有粘结预应力注浆;(7)锚具封堵保护;(8)安装连廊;(9)钢连廊临时支撑分级拆除卸荷;(10)后浇带混凝土浇筑;(11)施工及使用阶段结构检测。本发明可实现对结构裂缝、变形、挠度等质量控制的指标要求,且其施工工艺流程先进,经济合理,适用于外悬挑独立式单层或多层大悬臂钢结构连廊安装及其砼塔楼局部应用钢骨砼、有粘结预应力钢骨梁、无粘结预应力梁板砼施工的质量控制。
