再生混凝土空心楼盖作为一种新型结构有着很大的优越性,现浇混凝土空心楼盖结构具有自重轻、提高空间利用率、减少钢筋用量、抗震性能好、隔音性能优、综合造价低且施工工期短等优点,适用于大跨度、大空间的多高层建筑,能获得很大的使用空间和经济效益。为了研究将再生混凝土应用到空心楼板中的可能性,本文中设计了4块再生混凝土空心板,完成了静力实验,分析了不同再生混凝土粗骨料取代率对空心楼板承载力、裂缝、挠度的影响。
Recycled concrete hollow floor as a new type of structure has great advantages, cast-in-place concrete hollow floor structure with light weight, improve space utilization, reduce the amount of steel, good seismic performance, excellent sound insulation performance, low overall cost and construction Short duration and other advantages, suitable for large-span, large space, high-rise buildings, can get a lot of space and economic benefits. In order to study the possibility of applying recycled concrete to hollow slab, four recycled concrete hollow slabs were designed in this paper, and the static experiments were completed. The influence of different recycled aggregate concrete coarse aggregate ratio on the bearing capacity, crack and deflection of hollow slab Impact.
