Rigidity-controllable prestress corrugated web steel beam with vibration and vibration double-control function
The invention discloses a rigidity-controllable prestress corrugated web steel beam with a vibration and vibration double-control function. The rigidity-controllable prestress corrugated web steel beam comprises a corrugated web steel beam body, a rigidity-controllable prestress providing device control part and a tension part. The corrugated web steel beam is provided with an upper flange plate, a lower flange plate and corrugated webs fixedly connected between the upper flange plate and the lower flange plate. According to a tensioning part in the rigidity-controllable prestress providing device, a side opening type shell is fixed to a corrugated web steel beam structure through bolts and connected with a servo electric cylinder through bolts; the steel strand located at the center position in the height direction of the beam penetrates through the anchorage device and the baffle to be connected with a lifting lug on a pull rod of the servo electric cylinder. According to the control part, if stress data collected by a cable force sensor is lower than a comparison instruction in a PLC, a servo driver sends out a pulse signal to control a servo electric cylinder to complete tensioning of the steel strand. According to the expected result, when the prestress providing device with the controllable codes has the prestress loss of the steel strand, the tension of the steel strand can be automatically adjusted to meet the rigidity requirement of a component in actual engineering application.
具有振震双控功能的刚度可控型预应力波纹腹板钢梁，包括波纹腹板钢梁与刚度可控型预应力提供装置控制部分和张拉部分。波纹腹板钢梁有上、下翼缘板和它们之间固定连接的波纹腹板。刚度可控型预应力提供装置中张拉部分：用螺栓固定于波纹腹板钢梁结构上的侧开式外壳，与伺服电动缸通过螺栓连接；位于梁高度方向上中心位置处的钢绞线穿过锚具和挡板与伺服电动缸拉杆上的吊耳相连。控制部分：索力传感器收集到的应力数据若低于PLC中的比较指令，由伺服驱动器发出脉冲信号控制伺服电动缸来完成钢绞线的的张紧。预期成果可实现编码可控的预应力提供装置在出现钢绞线预应力损失时，将自动调整钢绞线的张拉来满足实际工程应用中构件的刚度要求。
