Description
技术领域technical field
本实用新型属于高架路桥的大型钢箱梁的安装施工技术，具体的涉及一种大型钢箱梁于桥墩顶部吊装后其端部的临时悬挂连接号装置。The utility model belongs to the installation and construction technology of a large steel box girder of an elevated road bridge, in particular to a temporary suspension connection number device at the end of a large steel box girder after hoisting on the top of a bridge pier.
背景技术Background technique
随着建筑工业和技术的日益发展，我国已经在沿海进行了多个海上高架桥梁的施工。为了实现高效率和高性能的高架梁施工，现有已经出现采用具有较大跨度的大节段钢箱梁，其长度已经达到80至130多米，重量高达2000多吨。由于大跨度钢箱梁多适用于海上高架桥梁，因此如何进行平稳和安全的吊装成为桥梁施工技术的关键。在一段钢箱梁进行吊装安装后，相邻的钢箱梁再进行吊装后需要进行两者的对接调整，此时由于钢箱梁在纵向和横向上均需要进行位置调整。由于设计施工要求，该单个钢箱梁的重心并不完全位于下部桥墩上，因此对钢箱梁进行临时定位以便于进行位置调整和定位成为需要解决的技术问题。但钢箱梁的吊装环境无法满足添加其他辅助高架工具进行临时悬挂定位的要求。With the development of construction industry and technology, our country has carried out the construction of many sea viaducts along the coast. In order to achieve high-efficiency and high-performance viaduct construction, there have been large-span steel box girders with large spans, the length of which has reached 80 to 130 meters, and the weight has reached more than 2,000 tons. Since long-span steel box girders are mostly suitable for offshore viaducts, how to carry out smooth and safe hoisting becomes the key to bridge construction technology. After a section of steel box girder is hoisted and installed, the adjacent steel box girder needs to be adjusted for docking after hoisting. At this time, the position of the steel box girder needs to be adjusted both longitudinally and horizontally. Due to design and construction requirements, the center of gravity of the single steel box girder is not completely located on the lower pier, so temporarily positioning the steel box girder for easy position adjustment and positioning has become a technical problem that needs to be solved. However, the hoisting environment of the steel box girder cannot meet the requirements of adding other auxiliary elevated tools for temporary suspension positioning.
