摘要：随着国内建筑市场的蓬勃发展，建筑领域中钢结构形式以其特殊的优越性能备受青睐，传统混凝土结构形式无法实现的外观造型因钢结构形式的出现得以扩充，越来越多的建筑结构采用钢混结合的形式呈现；受客观施工条件的影响，往往在下部结构施工完成后，钢结构专业施工受约束非常大，作业空间极其有限，如何克服相关问题成为钢混结构施工有效衔接的关键卡控点，也是各相关企业攻关研究的方向；笔者作为越南河内城市轨道建设项目参建者，通过对该项目钢结构安装施工技术的研究，同时自行研制便携式快速对接胎具，对“皇冠”式钢结构雨棚进行高位分段安装作业，有效解决了临近繁忙公路运营干线、安全风险等级高、作业时间有限等施工难题，降低了安全风险、缩短了安装周期、经济效益显著，在钢混结合的建筑钢结构领域中具有较强的实用性和指导意义。

Abstract： With the rapid development of the construction market in China， steel structure is favored with its special superior performance. The appearance that traditional concrete structure forms can not achieve is expanded because of the emergence of steel structure. More and more building structures adopt steel-concrete combined form. Affected by objective construction conditions， after the lower structure construction is completed， steel structure construction is very limited and the working space is extremely limited. How to overcome the relevant problems become the key point of the effective connection of steel and concrete structure construction， and also the direction of the research of relevant company. As one of the participants of Vietnam Hanoi City Railway construction project， through the research on the construction technology of the steel structure， the author developed a portable fast docking tire for high-level installation operation of "Crown" steel structure canopy， effectively solving the construction difficulties including adjacent busy road， high security risk level， limited operating time and so on， thus reducing security risks， shortening the installation cycle， and achieving significant economic benefits， which has a strong practical and guiding significance in the steel-concrete structure construction.
