摘要

摘要: 大跨度全螺栓连接钢结构安装过程经过多级连接施工,若构件仅按公称尺寸制作,其制造、运输、安装及环境温度变化均会产生尺寸偏差,易导致装配应力超限或螺栓无法连接,影响结构安全与装配效率。为此,提出大跨度全螺栓连接钢结构构件、安装单元、结构单元的尺寸链公差控制技术,通过公差分配与容差配合设计,容纳制造、运输、安装及环境温度变化产生的尺寸偏差,实现结构安装连接精准、高效且无应力装配,保障装配质量。并将该技术成功应用到某航站楼大跨度H型钢桁架屋盖工程中,实现了全螺栓装配高精度容差控制。

Abstract: The installation of long-span fully bolted steel structures is carried out using a multi-stage connection process. If components are manufactured solely based on nominal dimensions, dimensional deviations will occur due to manufacturing, transportation, installation, and environmental temperature changes. These deviations can readily lead to excessive assembly stress or failure in bolt connection, thereby affecting structural safety and assembly efficiency. A dimensional chain tolerance control technique for components, installation units, and structural units is proposed. Through tolerance allocation and fit design, the dimensional deviations caused by manufacturing, transportation, installation, and environmental temperature changes are accommodated. This enables accurate, efficient, and stress-free structural assembly and ensures high assembly quality. This technique was successfully applied to a long-span H-shaped steel truss roof structure at an airport terminal, achieving high-precision tolerance control in fully bolted assembly.
