摘要
模块化建筑是目前装配率最高的一类建筑形式,是建筑工业化发展的重要趋势。其中,模块化混凝土建筑在防火防腐、保温隔声、成本控制和居住舒适度等方面具有天然优势,逐渐受到工程界和科研界的关注。基于国内外模块化混凝土建筑发展历程,从混凝土模块类型、模块间连接节点类型、模块接缝受力性能、模块抗侧力体系方面进行文献梳理。结果表明,现有混凝土模块类型主要包括墙承重模块、柱承重模块和非承重模块。模块间主要连接方式包括湿法连接、螺栓连接和预应力筋连接,湿法连接整体性好、对装修友好,但现场湿作业多、施工速度慢;螺栓连接整体性略差,但施工方便、快捷。模块化建筑的受力体系主要包括模块-核心筒体系、模块-平台体系、非承重模块体系和叠箱体系,高层建筑基本采用前3种体系,多层建筑可采用叠箱体系。尽管国内外已有关于模块化混凝土建筑的工程应用研究,但对其受力性能的研究相对匮乏,严重滞后于工程实践;同时,混凝土模块自重大、模块间仍以湿法连接为主,大大增加了运输和吊装费用,降低了施工速度,严重阻碍了模块化混凝土建筑的发展。
Modular building is considered as the highest prefabricated rate and becomes a major trend in the field of building industrialization.Modular concrete building is gaining lots of attention due to the excellent properties on fire resistance,anti⁃corrosion,thermal and sound,economy and living comfort.The development of modular concrete building at home and abroad is introduced from four aspects,including concrete modular unit type,inter⁃module connection type and mechanical behaviors,lateral load resisting system.It is found that prefabricated modules can be classified into three structural systems depending on load transferring mechanism:wall supported module,column supported module and non⁃load bearing module.There are also three inter⁃module connections:wet connection on⁃site,bolted connection and pre⁃stressed reinforcement connection.Wet connection would provide good integrity and be friendly to finish,while too much work has to be done on site and the rate of construction is slow.Bolted connection has a less on⁃site work and rapid construction,while the integrity is worse than wet connection.There are four main lateral load resisting systems:module⁃core system,module⁃podium system,infilled frame system and stacked box structural system.High⁃rise building always applies the first three systems while multistory buildings can apply the last system.Although,there are several modular concrete buildings in practice,limited research can be found on their mechanical behavior.The related research far lags behind the engineering practice.In addition,concrete module has a higher weight resulting in handling and transportation issues and slow erection process due to wet connection,all the defects block the development of modular concrete building.
