Method for reinforcing concrete member by thermoplastic prepreg
The invention discloses a method for reinforcing a concrete member by a thermoplastic prepreg in the technical field of composite materials, and aims to solve the problems that in the prior art, modes such as column section enlargement or fiber cloth reinforcement are generally adopted, the process is complex, site construction is inconvenient, the durability of a structure is poor, and the construction cost is low. And the problem that the reinforcing effect of the concrete member is poor is solved. The method has the advantages that the process is simple, site construction is convenient, the reinforcing effect is good, and the service life of the structure is long, the thermoplastic prepreg has good acid, alkali and salt corrosion resistance and is hardly influenced by corrosion in a concrete member, and the durability of the structure is improved; the method for reinforcing by winding the thermoplastic prepreg into the grid is adopted, the process is simple, site construction can be achieved, the needed construction space is small, and the method is not limited by the shape and size of the concrete member to be reinforced; the prepreg is distributed in a grid shape, cracks can be effectively controlled, concrete constraint is provided, and the strength and toughness are improved.
本发明公开了一种复合材料技术领域的热塑性预浸料加固混凝土构件的方法，旨在解决现有技术通常采用增大柱截面或采用纤维布加固等方式，工艺较为复杂，不便于进行现场施工，且结构的耐用性较差，导致混凝土构件的加固效果较差的问题。本发明具有工艺简单、现场施工方便、加固效果好、结构服役寿命长等优点，热塑性预浸料具有良好的耐酸、碱、盐腐蚀的能力，在混凝土构件中几乎不受腐蚀影响，提高结构的耐久性；采用热塑性预浸料缠绕成网格加固的方法，工艺简单，可现场施工，需要的施工空间小，不受待加固混凝土构件形状和尺寸的限制；预浸料呈网格样分布，可实现对裂缝的有效控制，提供混凝土约束，提升强度和韧性。
