Integral assembly type precast concrete low-frequency floating floor slab
The overall assembly type prefabricated concrete low-frequency floating floor slab comprises a prefabricated concrete unit plate, vibration isolation systems, embedded connecting pieces, grouting materials and a reinforcing mesh, four round holes are formed in the prefabricated concrete unit plate, and the vibration isolation systems are arranged in the round holes; reinforcing meshes are embedded in the upper sides and the lower sides of the prefabricated concrete unit plates, every two adjacent prefabricated concrete unit plates are connected through an embedded connecting piece, and grouting materials are poured into the connecting positions of every two adjacent prefabricated concrete unit plates. The low-frequency spring stiffness elements with the natural vibration frequency not larger than. Hz are adopted for vibration isolation, factory prefabricated modular concrete standard unit plates are adopted for on-site overall assembly, the construction difficulty is effectively reduced, high-performance vibration reduction is achieved, meanwhile, on-site wet operation and installation work amount are greatly reduced, the structure is reasonable, construction is easy, and the construction period is shortened.
本申请公开了一种整体装配式预制混凝土低频浮置楼板，包括预制混凝土单元板、隔振系统、预埋连接件、灌浆料和钢筋网，所述预制混凝土单元板开设有四个圆孔，所述隔振系统设置在圆孔内，所述预制混凝土单元板上下两侧均埋置有钢筋网，相邻的两个预制混凝土单元板通过预埋连接件连接，相邻的两个预制混凝土单元板的连接处灌注有灌浆料。本申请采用自振频率不大于.Hz的低频弹簧刚度元件进行隔振，采用工厂预制模块化混凝土标准单元板进行现场整体装配，有效降低施工难度，实现高性能减振的同时，大大减少现场湿作业及安装工程量，构造合理，施工简单，缩短施工周期。
