Carbon fiber laminates manufacturers in China. pre-pressed cfrp laminates very ideal for bridge strengthening.
Pre–stressed CFRP plate system (Post-tension CFRP system)
Item #: CarbonPrep 320
Xinchor pre–stressed CFRP plate system(Post-tension CFRP system) includes anchoring devices and CFRP strip specially designed for bridge or long span beam reinforcement.
Feature:
Through the clips make the stress to carbon fiber laminates, make the laminates anchoring to concrete permanently, and that will add the stress to the concrete in bending direction.
The increasing stress can remove or retard the stress hysteresis of the added structures, make the existing crack reducing or even closed completely, so that to achieve real reinforcing.
Improve the bearing capacity of bridge structure,has incomparable advantages in large-span beam slab of flexural reinforcement.
Significantly reduce deformation of the structure and improve the bearing capacity of structure,decrease the crack width and
deflection deformation,and is suitable for large span beam slab of flexural reinforcement.
Improve the stiffness of structure ,and make full use of the material performance ,save a lot of materials and engineering cost.
High Strain, no peeling damage, achieve high performance of CFRP
enable CFRP be in strain status when adhere CFRP with substrates. no bending or curve between bonding member and pulling direction, hence no peeling strain caused. high strength bolt ensure the fast fixing, which could be double secure to avoid damages caused by peeling and bonding.
Characteristic of CFRP pre-stressed plate
• safe and reliable
• easy to install
• good economical
• reliable patent anchorage system
• suitable for large span beam slab of flexural reinforcement
• matching carbon fiber plate,adhesive,anchoring devices ensures the system matching
Advantage of Pre-stress CFRP Plate
• Active strengthening, no stain lagging
• Reduce the cracks of the component effectively and slow the development of cracks
• Increase the crack resistance and rigidity of the component, increase the loading capacity of component
• Fully achieve the high strength property of carbon fiber, both new and original component be under loading.
