Description
技术领域technical field
本发明涉及建筑材料技术领域，特别是涉及一种FRP水泥基预制组合板。The invention relates to the technical field of building materials, in particular to an FRP cement-based prefabricated composite board.
背景技术Background technique
压型钢板与混凝土组合楼板是指由压型钢板上浇筑混凝土组成的组合楼板，根据压型钢板是否与混凝土共同工作可分为组合板和非组合板。组合板是指压型钢板除用作浇筑混凝土的永久性模板外，还充当板底受拉钢筋的现浇混凝土楼(屋面)板。非组合板是指压型钢板仅作为混凝土楼板的永久性模板，不考虑参与结构受力的现浇混凝土楼(屋面)板。The composite floor of profiled steel plate and concrete refers to the composite floor composed of concrete poured on the profiled steel plate. According to whether the profiled steel plate and concrete work together, it can be divided into composite slab and non-composite slab. Composite slab refers to the cast-in-place concrete floor (roof) slab that the profiled steel plate is not only used as a permanent formwork for pouring concrete, but also as a tensile reinforcement at the bottom of the slab. Non-composite slab means that the profiled steel plate is only used as a permanent formwork for the concrete floor slab, and the cast-in-place concrete floor (roof) slab that participates in the structural force is not considered.
压型钢板组合板是最常见的组合板，其组成为：下部压型钢板做底模，上面浇筑普通钢筋混凝土，如图1、图2所示，这种结构充分发挥了钢板的抗拉性能和混凝土的抗压性能，大大提高了板的力学性能，但是自重较大，生产过程复杂，造价较高，应用范围小。近年来，一些研究者将压型钢板替换为FRP(纤维增强复合材料)板，上部的普通混凝土替换为轻质混凝土，但是由于轻质混凝土的延性差，抗震性能也不理想，破坏形式主要为脆性破坏，导致组合板结构强度较差。Profiled steel composite slab is the most common composite slab. Its composition is: the lower profiled steel plate is used as the bottom form, and ordinary reinforced concrete is poured on it. As shown in Figure 1 and Figure 2, this structure fully exerts the tensile properties of the steel plate And the compressive performance of concrete greatly improves the mechanical properties of the board, but the weight is large, the production process is complicated, the cost is high, and the application range is small. In recent years, some researchers have replaced profiled steel plates with FRP (fiber reinforced composite) plates, and replaced ordinary concrete on the upper part with lightweight concrete, but due to the poor ductility of lightweight concrete, the seismic performance is not ideal, and the main failure mode Brittle failure leads to poor structural strength of composite panels.
