目前许多住宅建筑中的大楼板,多为预应力或普通钢筋混凝土。其中预应力的工艺复杂,而普通钢筋混凝土的耗钢量又偏高,为了扩大双钢筋网片的应用范围,将大楼板中受力钢筋的部分改用预焊好的“双钢筋网片”。这样明显地简化了生产工艺,缩短蒸养时间,加快模板周转,提高了生产率。 1981年11月20日～12月4日,我们在天津市民用建筑壁板厂完成了两块双钢筋网片混凝土大楼板的结构试验工作。此次试验的主要目的是考察双钢筋网片混凝土大楼板在短期荷载作用下的抗裂性能、挠度变形、强度安全系数以及破坏特征。并分析其
At present, many building boards in residential buildings are mostly prestressed or ordinary reinforced concrete. The process of prestressing is complicated, and the steel consumption of ordinary reinforced concrete is high. In order to expand the application range of double steel mesh, the part of the reinforced steel in the building plate is replaced with prewelded double mesh. ". This significantly simplifies the production process, shortens the steaming time, speeds up template turnover, and increases productivity. From November 20, 1981 to December 4, 1981, we completed the structural test of two double-bar mesh concrete slabs at the Tianjin Citizen Building Wall Panel Plant. The main purpose of this test is to investigate the crack resistance, deflection and deformation, strength safety factor, and failure characteristics of double steel mesh concrete slabs under short-term loading. And analyze it
