Embodiment Construction

[0012] Referring to Fig. 1 to Fig. 4, the present invention is a kind of method utilizing fiber cloth to strengthen masonry. First, paste fiber cloth 2 on the surface of masonry 1, drill holes on the masonry pasted with fiber cloth, and implant fiber rivets 4 into through holes 3 of the masonry. Available common electric drill when drilling, the diameter of masonry through hole 3 is about 12mm, and the drilling depth is 50~60mm.

[0013] As shown in Figure 3, the fiber rivet 4 is a one-way fiber rivet made of carbon fiber cloth in a small roll shape. One end of the rivet is soaked and solidified with an adhesive to form a hard rod 41, and the other end of the rivet is disassembled into a tow shape 42 and unfolded into a fan. shape. The fiber rivet 4 can be made into a finished product, or can be made on the spot at the construction site.

[0014] Then insert the hard rod part 41 of the fiber rivet 4 into the through hole 3 of the masonry, and inject structural adhesive into ...

Abstract

The present invention relates to method of reinforcing masonry with fibrous fabric and matched clasping device. The method includes adhering fibrous fabric to the surface of masonry, drilling holes, planting fiber rivets into the holes, injecting structural glue into the holes for the combination between the fiber rivet and the masonry, and finally adhering one other layer of fibrous fabric. The fiber rivet is made through winding carbon fiber fabric and has one end adhered and cured into hard rod for inserted into hole in masonry and the other end developed to form fanned fiber bundle stretched outside the hole. The method and the matched clasping device can connect fibrous fabric to masonry firmly to reach excellent reinforcing effect.

Description

technical field [0001] The invention relates to masonry reinforcement engineering, in particular to a method for reinforcing masonry with fiber cloth. Background technique [0002] In the late 1980s and early 1990s, Fiber Reinforced Plastics (FRP) entered the field of civil reinforcement. Fiber reinforced composites in the form of sheets are usually called fiber sheets (FRP sheets). FRP material is characterized by light weight and high strength. The FRP reinforcement technology is to paste the FRP material on the surface of the stressed part of the component through an adhesive to improve the bearing capacity of the component. A prerequisite for this reinforcement method is that the fiber cloth is closely bonded to the surface of the component. If the fiber cloth is partially stripped or even completely separated from the surface of the component, the reinforcement effect will be partially lost or even completely lost. In fact, when the stress of the fiber cloth is high,...
