近年来,随着轻纺工业的发展,多层厂房及楼库工程逐渐增多。多层框架结构占地面积少,造型美观,且抗震性能、整体刚度较好,因此,这种结构形式将更多地被采用。目前,天津地区框架结构主要有柱梁板全现浇、现浇柱预制梁板和预制柱梁板全装配三种形式,其中现浇结构模板用量大、工期长;预制形式虽无此弊病,但二次湿作业多,节点接头做法复杂,施工困难,不易保证质量。为此,我们结合某三层配件仓库工程,从扩大预制单元和简化接头做法着手,搞了
In recent years, with the development of the textile industry, multi-storey factory buildings and building storage projects have gradually increased. The multi-layer frame structure has a small footprint, a beautiful appearance, and good anti-seismic performance and overall stiffness. Therefore, this type of structure will be used more. At present, there are three types of frame structures in Tianjin: cast-in-place cast-in-place columns, cast-in-situ precast beams, and prefabricated post-beam plates. In-situ cast-in-place structural forms require large amounts and long construction periods; There are many operations, complicated joint practices, and difficult construction, and it is difficult to ensure quality. To this end, we started with a three-tier fittings warehouse project and proceeded from expanding prefabrication units and simplifying joint practices.
