A CONSTRUCTION METHOD OF HYDRAULIC PAD-EXERTING-BOND PRESSURE FOR NOTABLY INCREASING BONDING STRENGTH BETWEEN FIBER SHEETS AND CONCRETE
-
摘要: 通过粘结机理和试验研究说明用纤维布加固混凝土时施加粘贴接触压的必要性。提出一种简便易行的液垫施加接触压施工方法,并介绍在南方某高校图书馆部分屋面梁加固中的应用情况。Abstract: Via bonding mechanism and experimental study, the necessity of exerting contact pressure to the bonding interface between fiber s heets and concrete was indicated. A convenient and practical construction techni que of hydraulic pad-exerting-pressure was proposed. An application of the pro posed method in the strengthening of roofing beams of a university library in So uth China was described.
