GFRP rebar is a novel product that combines the advantages of fiber-reinforced plastic (FRP) and concrete to create a strong and durable structural element. FRP is a composite material that consists of a polymer matrix reinforced with fibers, such as glass, carbon, or polyester. FRP has high strength-to-weight ratio, corrosion resistance, and design flexibility. Concrete is a widely used construction material that has high compressive strength, fire resistance, and low cost. By combining FRP and concrete, Frp Spiral Column can achieve enhanced performance in terms of load-bearing capacity, deformation, and durability.

Product Features

GFRP raber consists of an external FRP tube that is filled with concrete and internally reinforced with FRP spiral bars. The FRP tube provides confinement to the concrete core, increasing its strength and ductility. The FRP spiral bars provide additional reinforcement to the concrete, preventing strain-softening behavior and improving the stiffness and energy absorption of the column.

GFRP raber can be fabricated in various shapes and sizes, such as square, circular, or rectangular cross-sections. The corner radius of the square columns can be adjusted to optimize the confinement effectiveness of the FRP tube. The FRP tube can also be customized with different colors, textures, or patterns to suit the aesthetic requirements of the project.

GFRP raber can be easily installed on site using simple tools and techniques. The FRP tube can be cut to the desired length and joined with adhesive or mechanical connectors. The concrete can be poured into the FRP tube using conventional methods or precast in advance. The FRP spiral bars can be inserted into the concrete before or after curing, depending on the design specifications.

GFRP raber can withstand various environmental conditions and loads, such as axial compression, bending, shear, torsion, impact, earthquake, fire, or corrosion. The FRP tube protects the concrete from moisture, chemicals, or temperature variations, extending its service life. The FRP spiral bars enhance the ductility and toughness of the concrete, enabling it to resist cracking or spalling under extreme loading scenarios.
