Steel structure cantilever beam construction method

ZENG JUN

The invention discloses a steel structure cantilever beam construction method, which belongs to the technical field of building engineering and comprises the following steps of BIM (Building Information Modeling) technical simulation, steel structure in-site manufacturing and processing technology, construction early-stage preparation, steel structure in-site installation and construction technology and inspection and acceptance. The invention provides a complete set of mature construction technology, mainly aims at hoisting and butt joint of the primary and secondary beams and fixing of high-strength bolts, solves the problems that an existing steel structure cantilever beam is high in construction complexity, easy to re-rust, high in construction risk and the like, and effectively reduces the cost while ensuring the integral construction integrity.

本发明公开了一种钢结构悬挑梁施工方法，属于建筑工程技术领域，包括以下步骤：BIM技术模拟、钢结构场内制作加工工艺、施工前期准备、钢结构现场安装施工工艺和检查验收。本发明提供了成熟的成套施工工艺，以主次梁吊装，对接与高强螺栓的固定为主，解决了现有的钢结构悬挑梁施工复杂性高、易返锈及施工危险性高等难题，在保证整体施工完整性的同时有效降低了成本。
