Installation method for oblique crossing steel pipe and grid column type outer frame barrel body structure
The invention relates to an installation method for an oblique crossing steel pipe and grid column type outer frame barrel body structure, and belongs to the technical field of building steel structure construction. The installation method comprises the following operation steps that a supporting steel pipe is positioned on a base, and the welding and fixing process of the supporting steel pipe and the base is completed according to the installation inclination and span of a grid column; then the angle inclination of a sling is adjusted through a chain block to align the hoisting process of the grid column; then a pair of symmetrically distributed grid columns and the supporting steel pipes are temporarily fixed through a plurality of butt joint lug plates which are annularly distributed at equal intervals; then operation platforms are installed on the pair of grid columns, and then oblique crossing steel pipes are hoisted to be aligned with the upper ends of the grid columns; and after the oblique crossing steel pipe and grid column type outer frame barrel body structure forms a stable A-shaped structure system, welding work is carried out. The method has the advantages of high construction safety and reliability, simple construction method and short construction period. The inclination angles and the axis positions of the oblique crossing steel pipes and the grid columns areguaranteed, shaking is effectively reduced, and the hoisting accuracy is improved.
本发明涉及一种斜交钢管网格柱外框筒体结构安装方法，所属建筑钢结构施工技术领域，包括如下操作步骤：在基底上对支撑钢管进行定位，并根据网格柱的安装斜度及跨度完成支撑钢管与基底的焊接固定过程。接着通过手拉葫芦调节吊索的角度倾斜来对位网格柱的吊装过程。接着将一对呈对称式分布的网格柱与支撑钢管间通过若干呈等间距环形分布的对接耳板进行临时固定。然后再在一对网格柱上均安装好操作平台，再吊装斜交钢管与网格柱上端对位。当斜交钢管网格柱外框筒体结构形成稳定的A字型结构体系后进行焊接工作。具有施工安全可靠性高、施工方法简单和施工周期短的优点。保证了斜交钢管网格柱的倾角、轴线位置、并有效减少晃动，提高吊装的准确性。
