Description
Technical Field
The invention relates to the field of building materials, in particular to a novel environment-friendly glass reinforced plastic bar.
background
The reinforcement is used as a building material and is arranged in reinforced concrete and prestressed reinforced concrete structures. In the engineering construction of subway tunnels, bridges and the like, the commonly used reinforcing steel bars are steel bars, the reinforcing steel bars refer to steel bars for reinforced concrete and prestressed reinforced concrete, and the cross section of the reinforcing steel bars is circular and sometimes square with round corners. The shape of the steel bars is various, including plain round steel bars, ribbed steel bars and twisted steel bars; there are many types, generally classified by chemical composition, manufacturing process, rolling profile, supply form, diameter size, and use in construction. The reinforcing steel bar for reinforced concrete is straight bar or wire rod-shaped steel for reinforcing the reinforced concrete, and the shapes of the reinforcing steel bar are smooth reinforcing steel bar and deformed reinforcing steel bar. The steel reinforcement is mainly subjected to tensile stress in the concrete. The deformed reinforcing steel bar has larger bonding capacity with concrete due to the action of the ribs, so that the deformed reinforcing steel bar can better bear the action of external force. Steel reinforcement is widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.
the existing reinforcing steel bar is not easy to cut due to the material, damage is easily caused to an -opening machine during cutting, in addition, the reinforcing steel bar is heavy in weight and not easy to operate, and the construction difficulty and the labor intensity of workers are increased.
