The zipper on the market is generally a chain composed of metal or plastic engaging teeth arranged on left and right cloth belts, and the left and right engaging teeth are engaged by pulling and extruding the zipper head, so that the opening of the chain position is closed. The teeth of the zipper usually have a concave portion and a convex portion, and the convex portion of the zipper is pressed into the concave portion by pulling and pressing the slider, so that the zipper is buckled into a whole which is not easily separated. The zipper used in life at present is mainly used for clothes, bags, tents and the like. The current zipper form has the following drawbacks and is not suitable for the engineering field: (1) The connection strength is not high, and the connection is easy to be disengaged under the action of external force; (2) The zipper is unstable in connection, and can be transmitted to adjacent meshing teeth only if one part is disengaged; (3) The connection between the tooth and the cloth is glue connection, and the connection strength is not high.
FRP cloth (fiber reinforced composite) is a high-performance material formed by mixing fiber materials and matrix materials according to a certain proportion, has the characteristics of light weight, high strength and corrosion resistance, and is increasingly applied to the field of civil engineering reinforcement. One of the most common methods is to post FRP cloth to the outer surface of the reinforced Liang Zhuban. In this reinforcing method, the FRP cloth is generally connected to each other by applying epoxy resin thereto in a lap joint manner. The method has certain disadvantages, high required reinforcement process, high requirement on training skills of workers, discrete reinforcement effect and difficult quality control.
