Multi-box groove type FRP profile fiber sea sand concrete slab structure
The invention discloses a multi-box groove type FRP profile fiber sea sand concrete slab structure. The concrete slab structure comprises a box body formed by splicing CFRP multi-box-groove type plates, the box body is provided with a filling groove used for containing fiber sea sand concrete, and the CFRP multi-box-groove type plates are provided with GFRP plates. The damage form of the concrete slab structure is that the GFRP layer firstly loses efficacy (is snapped) so as to provide failure early warning, and then the cross section stress redistribution, the CFRP and the fiber concrete with high ductility continue to bear load until the concrete layer is crushed into final damage. According to the concrete slab structure, materials are convenient to obtain, formworks are not needed, the compression resistance and tensile resistance are good, and economic benefits are prominent. And moreover, materials can be directly taken from the sea, the transportation amount of the raw materials can be greatly reduced, and the cable is easy to transport and install, convenient to construct, high in corrosion resistance and designability, capable of adapting to severe marine environments, high in applicability in near and long ocean island service environments and suitable for application and popularization.
本申请公开了一种多箱槽型FRP型材纤维海砂混凝土板结构。该混凝土板结构包括由CFRP多箱槽型板拼接成的箱主体，箱主体具有用以容纳纤维海砂混凝土的填充槽，CFRP多箱槽型板设有GFRP板。该混凝土板结构的破坏形式为，GFRP层首先失效(拉断)以提供失效预警，然后截面应力重分布，CFRP和具有高延性的纤维混凝土继续承担荷载，直到混凝土层被压碎为最终破坏。本混凝土板结构，取材方便、无需模板、抗压抗拉性能良好、经济效益突出。且可直接从海中取材能够大大降低原材料运输量，易于运输和安装，便于施工，耐腐蚀性和设计性强，能够适应恶劣的海洋环境，在近、远洋岛礁服役环境中适用性强，适合推广使用。
