浅谈装配式建筑在核岛厂房土建施工中的应用

Discussion on the Application of Prefabricated Building in the Civil Construction of Nuclear Island Plant

近年来,随着建筑业朝着工业化方向不断发展,应用工业流水线高效生产构配件的装配式建筑得到越来越广泛应用。通过调查装配式建筑发展现状,结合核岛厂房抗震要求高、结构自重大、施工定位精度要求高等特点,分析装配式建筑在核岛厂房应用面临四项难点:连接节点受力薄弱,构配件自重及场地限制制约吊装,装配精度控制难度大,难以实现规模经济性。最后根据工程实践经验,提出核岛厂房应用装配式建筑的五项可行建议:创新节点连接技术,提升现场装配精度,提升吊装能力,首件模拟试验,优先应用于关键路径工作,供核电相关从业人员参考。

In recent years,with the continuous development of the construction industry towards industrialization,the prefabricated building using the industrial assembly line has been more and more widely used.By investigating the prefabricated construction development status,combined with the nuclear island plant seismic requirements,structure from the major,construction positioning accuracy requires higher characteristics,analysis of prefabricated buildings in nuclear island plant application faces four difficulties:connection node force weak,component weight and site limit lifting,assembly accuracy control is difficult,difficult to achieve scale economy.Finally,according to the engineering practical experience,five feasible suggestions are put forward for the application of prefabricated buildings in the nuclear island plant:innovate the node connection technology,improve the on-site assembly accuracy,improve the lifting capacity,the first simulation test,give priority to the key path work,for the reference of nuclear power related practitioners.
