双扇人防门门框先置安装支撑体系的设计

Design of Pre-installed Support System for Double-leaf Air-defense Door Frame

针对出入口、连通口等部位的双扇人防门,设计了两种双扇人防门门框先置安装支撑体系。对这两种双扇人防门门框先置安装支撑体系进行了仿真分析,得到支撑体系的位移云图,以及门框与支撑杆件的应力云图。通过对比,选取了较优的先置安装支撑体系,为双扇人防门门框安装方式的改进提供了技术参考。

For the double-leaf air-defense door at the entrance,exit,connecting port,etc.,two types of pre-installed support system for double-leaf air-defense door frame were designed. The two pre-installed support systems for double-leaf air-defense door frame were simulated and analyzed,and the displacement cloud diagrams of the support systems,as well as the stress cloud diagrams of the door frames and the supporting members were obtained. Through comparison,a better pre-installed support system was selected,which provided a technical reference for the improvement of the installation method of the double-leaf air-defense door frame.
