For the construction of FRP grating, the cable routing should be considered, the cable bending radius of the largest cross-sectional area of the bridge installation content, and the cable arrangement should be considered. The cables should be laid out before the cables are laid. First, draw a table to arrange the construction.
The ladder must be strong, and the user's word except the feet of the ladder is 40 to 60 cm drawstring to prevent splitting. FRP grating fiber reinforced plastic, FRP. Reinforced plastic of glass fiber or its products, the title of glass fiber reinforced plastic, or glass fiber reinforced plastic. Because the types of resins used are different, so it is polyester glass fiber reinforced plastic, glass fiber reinforced epoxy resin, phenolic FRP said.
Carbon fiber reinforced plastic, organic fiber reinforced plastic. Reinforced plastic materials using carbon fiber or its products, the term carbon fiber reinforced plastic, belongs to carbon fiber composite material; organic fiber or its products, such as aramid fiber reinforced plastic material, the title of organic fiber reinforced plastic. These two kinds of steel, non-metallic composite materials. Resin. Resins refer to organic substances with different and high relative molecular weights, solid, semi-solid or pseudo-solid, and sometimes liquid. Broadly speaking, resins are used to refer to any polymer that is the basic material of plastics. Unsaturated polyester, epoxy, phenolic and other resins, after adding curing agent and heating, will form insoluble and infusible cured products, so they are called thermosetting resins; polyethylene, polypropylene, polyvinyl chloride, polystyrene, etc., can be It is heat-molded again, so it is called a thermoplastic resin, and is often called a plastic. Reinforced materials. When added to the resin, the mechanical properties of the resin product can be significantly improved, those fibrous or fabric-like fillers are called reinforcing materials.
