摘　　要：随着新型城镇化的推进,装配式钢结构建筑比例逐年提高,但是现有钢结构体系用于村镇建筑时存在着住宅品质不优、构件标准化程度低、运输安装不便、建造质量低下、污染及浪费严重等问题,亟需研发低成本、易安装、生态化的村镇装配式住宅轻钢结构体系以及相应的建造技术。轻钢框架-网格墙结构不仅具有抗震性能优良、构件轻便、易于运输的优点,而且节点可采用完全装配式的螺栓连接或自攻螺钉连接,施工安装简便。为了研究这种结构形式的简易施工关键技术以及抗侧性能,建造了一栋采用全螺钉连接的轻钢框架-钢、木、竹网格墙混合结构体系的单层房屋,并对其进行了原位试验。以该工程中的一榀轻钢框架-网格墙为例,从柱脚、基础、框架安装、钢网格墙安装、墙板安装等方面阐述轻钢框架-网格墙的简易施工建造技术,并通过原位静力试验得到了其抗侧性能。研究表明,这种轻钢框架-网格墙易于安装,能够节省人力物力,适于在村镇地区推广应用,且采用该建造技术完成的轻钢框架-网格墙结构的抗侧性能能够满足设计要求。With the promotion of new urbanization,the proportion of prefabricated steel structure buildings has increased year by year.However,the existing steel structure systems applied in rural buildings face problems such as poor living quality,low level of components standardization,inconvenient transportation and installation,low construction quality,and serious pollution and waste.It is urgent to develop low-cost,simple-constructed,ecological prefabricated light steel structure systems residence and corresponding construction technologies.The light steel frame-grid wall structure not only has the advantages of excellent seismic performance,light components and easy transportation,but also can be wholly connected by bolts or self-tapping screws,which is convenient for installation.In order to study the simple construction technology and lateral performance of this structure,a single-story house with a steel frame-steel,wood and bamboo grid wall hybrid structure system wholly connected by screws was built,and its in-situ experiment was carried out.Taking a light steel frame-steel grid wall in this project as an example,this paper expounds the simple construction technology of the light steel frame-steel grid wall from the column base,foundation,installation of frame and steel gird,and fixing of wallboard,and its lateral performance was obtained through the in-situ static experiment.The research shows that the light steel frame-steel grid wall is easy to install,which can save manpower and material resources,and is suitable for application in rural areas,and the lateral performance of the light steel frame-steel grid wall with this construction technology can meet the design requirements.
