摘要
钢结构屋盖作为一种新技术应用,其自身轻、强度高、整体性好、变形能力强等优点是混凝土结构无法比拟的。钢结构超大跨度、超大空间,使建筑的使用功能更加丰富。张悬梁结构作为钢结构的一种类型,属于大跨度预应力结构体系,构造简单、受力合理均匀,是一种很好的自平衡体系。其施工专业性强,施工技术、质量、安全控制难度很大。解决张悬梁施工技术、质量、安全问题具有着重要意义。
        As a new technology application, steel structure roof is light, strong, good in integrity and strong in deformation ability.The point is unmatched by the concrete structure. The steel structure makes the building more functional, with a large span and a large space.The advantages of the steel structure are drastic and exquisite. The cantilever beam structure is a type of steel structure and belongs to the large-span prestressed joint.The structure system is simple in structure and reasonable in force. It is a good self-balancing system. But the construction is professional,and it is very difficult to control the construction technology,operation, quality and safety. Therefore, it is of great significance to solve the construction technology, quality and safety of the cantilever beam.
