    服务工程实际需求,提升装配式建筑建造效率

    ——中国工程建设协会标准《钢筋桁架叠?#19979;?#26495;应用技术规程》广泛征求意见

     

    目前,我国正在大力发展装配式建筑,积极促进建筑产业的转型升级,装配?#20132;?#20957;土结构中,楼板、楼梯是应用最广泛的预制构件。由于抗震、结构整体性等要求,钢筋桁架叠?#19979;?#26495;应用广泛。但目前有关国家标准、行业标准中的规定主要采用之前的研究成果并借鉴现浇楼板构造要求,部分要求?#26434;?#39044;制构件的生产及安装效?#35270;?#36739;大的不利影响。

    基于以上情况,建研科技股份有限公司联合龙信建设集团有限公司申请制订中国工程建设协会标准《钢筋桁架叠?#19979;?#26495;应用技术规程》。编制组集合了清华大学、同济大学、华润置地、宝业集团等16?#19994;?#20301;,涵盖了科研、设计、生产、施工全链条经验丰富的单位。先后开展了预制?#35013;?#19981;出筋的板端支座节点、密拼叠合板抗弯?#38405;?#21644;密拼缝双向板力学?#38405;?#31561;试验研究与设计方法研究,充分验证了安全性与可靠性;同时根据桁架叠合板的特点,提出了针对性与可操作性强的生产、安装、质量检验与验收方法。

    该《规程?#26041;?#35299;决长期以来困扰行业的预制?#35013;?#22806;伸钢筋、密拼接缝叠合板不能用于双向板的难题,可?#32422;?#22823;地提升生产、施工效?#30465;?#35813;《规程》服务于工程实际需求,推动行业进步,将为装配式建筑工程提供扎实的标准支撑,预期可?#28304;?#36896;可观的经济效益与良好的社会效益。

    《规程》目前正在全国广泛征求意见,下一阶段将根据反馈意见进一步修订完善、提交审查,争取早日推出。
