摘要:
提出预应力钢丝绳加固钢筋混凝土框架节点的加固方法,通过绳扣进行钢丝绳搭接锚固性能试验及钢丝绳孔道注胶搭接锚固的拉拔试验,验证搭接锚固方法的可行性.由试验结果分析可知,采用两端分别拧紧绳扣的方法可实现对已完成预应力张拉的钢丝绳的临时搭接锚固;采用密封孔道水平压力注胶的施工方法可保证胶体充满孔道确保施工质量;试验中采用的植筋胶对钢丝绳具有较好的锚固效果,可在较小锚固长度的情况下保证钢丝绳拉断而无明显滑移.
Abstract:
A new method of strengthening RC frame joint with prestressed steel wire-rope stirrups was proposed. Experiment of clamping steel wire-ropes which are prestressed with wire line hitchs and anchored wire ropes by injecting glue was conducted to show the feasibility of this reinforcement method. The results show that the lapped prestressed ropes could be temporarily anchored by tightening wire line hitchs installed at both sides of the ropes; the method of horizontal pressure injection after sealing pore channel can fill the pore with glue; the bar glue anchorage of steel wire-rope is reliable, wire ropes are broken without obvious slippage in a short anchorage length.
