Benefits of technology

This patented technology improves upon existing methods by adding an external protection layer made from fibers or plates that are added during casting process on top of the casted part's steel structure. These layers help prevent damage caused when there comes into contact with other parts like bolts used laterally across the entire length of the building. Additionally, this method allows for easy installation without requiring significant labor hours due to its low weight compared to traditional ways of reinforceing structures. Overall, these technical improvements make the reintroduction technique more efficient and effective than previous techniques while reducing costs associated with constructing new bridges overpasses.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the quality and efficiency of producing high-strength FRP composites that could improve structural integrity without adding weight compared to traditional methods like iron frames and other metals.

Embodiment

[0021] Such as figure 1 As shown, the present invention is mainly composed of a concrete structure layer, a primer layer, a leveling layer, an impregnated glue layer and an FRP fiber material layer laminated on the surface in sequence. Wherein, the primer layer, the leveling layer and the impregnated adhesive layer are respectively composed of the primer adhesive, the leveling adhesive and the impregnated adhesive in the structural adhesive. The structural adhesive plays an important role in the present invention. It plays a bonding role between the FRP fiber material and the concrete structure layer and transmits the macroscopic mechanical properties in the system.

[0022] Before painting the primer on the concrete surface, it is necessary to treat the surface of the loose and weak concrete structure layer to the hard interface of the concrete. Then apply the primer to improve the strength of the concrete surface and the bonding of the concrete structure layer and the adhesive

Abstract

The invention discloses a structure of sticking a fiber reinforce plastic (FRP) fiber material on the surface of concrete, which is characterized by mainly comprising a concrete structure layer, and a primer layer, a leveling layer, an impregnated adhesive layer and an FRP fiber material layer which are stacked on the surface of the concrete structure layer in turn. The invention also discloses a method for implementing the structure of sticking the fiber reinforce plastic (FRP) fiber material on the surface of the concrete, which is characterized by mainly comprising the following steps of: pretreating the loose and weak surface of the concrete structure layer until the surface of the concrete structure layer forms a hard interface; uniformly coating a primer on the formed hard surface of the concrete structure layer, and the like. The invention can obviously improve the rigidity and hardness of reinforced concrete members; meanwhile, the FRP fiber material is embedded in a concrete cover, so the FRP fiber material can be protected, the accident load action such as wear and impact is avoided and the invention is suitable for reinforcing bridge decks and continuous beam hogging moment areas.
