【摘要】 模块化箱体建筑是结构装修一体化的箱体模块在工厂生产,然后在现场将箱体相互连接起来的装配式建筑体系,适用于需要快速建造或者在使用寿命期内需要迁移的医院、学校以及防灾救灾据点等建筑。以一个四层建筑底部两层足尺钢框架箱体模块为对象进行加载与拆装试验,研究其在使用寿命期间拆装及其对结构性能的影响。结果表明:螺栓连接的模块化箱体建筑可以实现在10min内拆除或安装一个箱体,施工建造效率较高;在正常使用荷载、强风荷载或设防地震作用作用后分别拆装1次,拆装对结构性能基本无影响;拆装过程中主体结构和结构构件均未发生明显损坏,非结构构件单次拆装损耗率小于10%。更多还原

【Abstract】 Modular box building is a prefabricated building system in which the box module with integrated structure and decoration is produced in the factory, and then the box is connected to each other on the site, which is suitable for hospitals, schools and disaster prevention and relief bases that need to be built quickly or need to be relocated during their service life. In this paper, the loading and disassembly tests of a two-story full-length steel frame box module at the bottom of a four-story building are carried out to study the disassembly during its service life and its influence on the structural performance. The results show that a bolt-connected modular box building can be dismantled or installed within 10 minutes, and the construction efficiency is high. It is disassembled once after normal service load, strong wind load or fortification earthquake load, and the disassembly has no effect on the structural performance. In the disassembly process, the main structure and structural components were not significantly damaged, and the single disassembly loss rate of non-structural components was less than 10%.更多还原
