Fiber bragg grating intelligent steel strand and prestressed structural member for building
The invention relates to the technical field of building structural members, in particular to a fiber bragg grating intelligent steel strand and a prestressed structural member for a building. On one hand, the invention relates to a fiber bragg grating intelligent steel strand which comprises a central composite rib and optical fibers. A strain grating and a temperature compensation grating are arranged on the optical fiber; the buffer assembly comprises a guide pipe and a buffer plate; the temperature compensation grating is positioned in the guide tube; the buffer plate and the temperature compensation grating are relatively fixed, and a gap is reserved between the periphery of the buffer plate and the inner wall of the guide pipe; and the guide pipe is filled with buffer grease. On the other hand, the invention relates to a prestressed structural member for a building, which comprises a concrete structure and an intelligent fiber bragg grating steel strand, and the intelligent fiber bragg grating steel strand is arranged in the concrete structure. According to the fiber bragg grating intelligent steel strand and the prestressed structural member for the building, the problem that the temperature compensation precision is poor due to vibration during prestressed tensioning can be effectively solved.
本申请涉及建筑结构构件的技术领域，尤其是涉及一种光纤光栅智能钢绞线和建筑用预应力结构构件。一方面，本申请涉及一种光纤光栅智能钢绞线，包括中心复合筋和光纤；光纤上设置有应变光栅和温度补偿光栅；缓冲组件包括导向管以及缓冲板；温度补偿光栅位于导向管内；缓冲板和温度补偿光栅相对固定，缓冲板的周缘和导向管内壁之间留有间隙；导向管内部填充有缓冲油脂。另一方面，本申请涉及一种建筑用预应力结构构件，包括混凝土结构和光纤光栅智能钢绞线，光纤光栅智能钢绞线设置在混凝土结构内部。本申请提供的一种光纤光栅智能钢绞线和建筑用预应力结构构件，能够有效解决预应力张拉时因震动造成的温度补偿精度较差的问题。
