干挂石材在预制框架结构改造工程中的应用

Application of Dry-hang Stone Material in Fabricated Frame Structure Rebuilding Project

结合中纪委2号办公楼装修改造工程实例,介绍了在钢筋混凝土装配式框架剪力墙结构上悬挂石材幕墙的设计施工技术。针对该办公楼外装饰面由仿石涂料改为石材饰面的设计要求,在对原有装配式框架剪力墙结构制定安全有效的加固方案时,运用背栓式干挂体系,解决了施工中的技术难题。

According to project practice - No. 2 office building of Central Commission for Discipline Inspection of the CPC, design and construction technology of hanging stone curtain wall on the reinforced concrete fabricated frame shear wall structure is introduced. In order to change exterior facing from ashlar brick to stone facing based on design, when making the measures to reinforce the original fabricated frame shear wall structure, back plug dry-hang system has been applied to settle the difficult technology problems in construction.
