摘   要：现有碳纤维布（CFRP）预应力张拉设备结构复杂，施工繁琐，不能够满足现场施工要求。试验研究发现，仅粘贴一层碳纤维布对被加固构件的性能提升很小，不能满足加固要求。通过试验研究，研发了一种可以对双层碳纤维布同时张拉的加固方法和施工工艺，并采用预紧螺栓锚固钢板对碳纤维布锚固，对9根试验梁进行了试验。结果表明，该张拉设备操作方便，施工快捷，可大大提高施工效率，通过锚固措施，可有效防止碳纤维布在加载过程中发生滑移和大面积剥离现象。

Abstract: The existing CFRP pre-stressed streching equipment with complex structure, construction tedious, can not satisfy site construction requirements. Experimental research found that, only a piece of carbon fiber can’t enhance performance of the strengthened beam, which can not meet requirements of reinforcement. Through experimental research, a double CFRP can be tensioned reinforcement methods and construction technology at the same time, which is used by preloaded bolt anchorage steel to anchorage the CFRP, and experiment of 9 test beams is studied. The results show that, the tensioning device is easy to operate, quick construction, and can greatly improve efficiency of construction, which can effectively prevent the CFRP in process of loading slip and large area of stripping phenomenon by anchoring measures.
