摘要
主要分析了预装拼装技术的基本概念、国内外研究现状和主要工程优势,包括可以有效缩短工期、确保施工质量、提高施工安全性、更加环保和现场作业的系统化程度高。2016年起,建筑单体预制率不应低于40%或单体装配率不低于60%。环卫重大设施建设项目具有其特殊性,功能性建筑的标准化程度低、区域位置特殊对建筑本身的环保功能要求高、构件尺寸种类多且不规则、施工次序也对预制拼装技术的实施有影响。在综合考虑施工质量、成本、建设性能要求等要素后认为,对于环卫重大工程的预制率,需要依据工程项目的具体特点进行控制。
The basic concepts,the research status at home and abroad,and the main engineering advantages of the preassembled assembly technology are main analyzed,including able to effectively shorten the construction period,to ensure the construction quality,to improve the construction safety,and more environmental protection and high degree of systematic operation in the fields.Starting from 2016,the prefabrication rate of building unit should not be less than 40%or the assembly rate of building unit not less than 60%.The construction project of major sanitation facilities has its particularity.The low standardization of functional buildings,the high environmental protection function of the buildings at the special area location,the varied and irregular component dimensions,and the construction sequence also affect the implementation of prefabricating assembly technology.After comprehensively considering the construction quality,cost,construction performance requirements and other elements,it is believed that the prefabrication rate of major environmental sanitation projects needs to be controlled according to the specific characteristics of the engineering projects.
