Reinforcement method for existing concrete structures: "Outplate Method"

Reinforcement method for existing concrete structures: "Outplate Method"

Fixed and bonded to the existing concrete structure! You can achieve a significant reinforcement effect with a small amount of reinforcement material.

The Outplate method is a reinforcement technique that involves tensioning prefabricated CFRP plates (outplates) with anchoring bodies at both ends, fixing and bonding them to existing concrete structures. Compared to conventional continuous fiber sheet bonding methods, tensioning the outplates allows for the introduction of prestress into the concrete, enabling significant reinforcement effects with a smaller amount of reinforcement material. Since thin CFRP plates are used as tensioning materials, there is almost no change in the external appearance or cross-section after reinforcement, making it particularly suitable for the construction of RC and PC hollow slab bridges, and it can also be applied to external cable reinforcement of steel bridges. 【Features】 ■ High bending reinforcement effect and crack control effect ■ Recovery of deflection ■ Improved durability ■ Minimal maintenance ■ Reinforcement over the supports of continuous girders can be done from the underside ■ Excellent aesthetic quality *For more details, please refer to the PDF document or feel free to contact us.

Gainamesh method [fall prevention measures]

Gainamesh method [fall prevention measures]

It has excellent durability, conforms to the curved surfaces of tunnels, and prevents the spalling of concrete fragments.

■NETIS Registered, Registration Number: KK-240048 ■High-strength aramid fibers reliably prevent the spalling of concrete pieces. This construction method aims to prevent the spalling of concrete pieces in concrete structures using GFRP shape retainers and high-strength aramid fiber mesh, ensuring the safety of users of the structures. *This meets the quality standards specified in the NEXCO Tunnel Construction Management Guidelines. 【Features】 The mesh part allows for visual inspection after construction. By using high-strength aramid, there is less alkali deterioration due to groundwater, and since it does not conduct electricity, it can also be applied in railway-related tunnels. Installation is quick and easy, as it only requires driving in strike anchors. Additionally, if any deformation is observed after construction, maintenance such as removing and reattaching the fixing screws can be easily performed. By using a locking K-nut with a friction ring (leaf spring), it provides a function to prevent detachment, enhancing safety. This locking K-nut meets NAS standards, which are specified as verification items during material approval by NEXCO.

Underground buried tank leak detection device with inner FRP double-shell structure.

Underground buried tank leak detection device with inner FRP double-shell structure.

Eliminate abnormal pressure fluctuations in the small space between the outer shell of the SF double-shell tank made of FRP and the inner shell made of steel at low cost! No need for repairs at each location every time an anomaly is detected!

Underground tanks at facilities handling hazardous materials such as SS have been equipped with SF double-walled tanks since around 1994, and as of March 31, 2011, a total of 41,572 SF double-walled tanks have been installed. In this situation, during leakage inspections of underground tanks, abnormal pressure fluctuations have been confirmed in the small space between the outer FRP shell and the inner steel shell of the SF double-walled tanks. Even if the cause is identified and the leakage point is repaired, there are cases where new abnormalities appear elsewhere, or abnormalities in different locations are confirmed several years after the first repair, making it impossible to guarantee that past repair work will be completed in one go. However, the fire department is also struggling with the reality that they cannot provide strong guidance due to economic issues. Our company's "Underground Storage Tank Leakage Detection Device with Inner FRP Double-Wall Structure" offers a low-cost solution to these problems. 【Benefits】 - There is no need to repair each location every time an abnormality is detected. - The number of facilities that cannot be repaired due to economic reasons decreases, reducing the risk of accidents. - Even facilities that cannot be inspected frequently can be safely monitored from a remote location. *For more details, please download the PDF or contact us.

Gain CF sheet method [Structural reinforcement and peeling prevention measures]

Gain CF sheet method [Structural reinforcement and peeling prevention measures]

High-strength carbon fiber "Gaina CF Sheet" demonstrates significant reinforcement and repair effects on concrete structures without applying any load.

The Gain CF Sheet Method is a technique that involves applying carbon fiber sheets treated with high adhesive penetration to concrete structures for the repair and reinforcement of tunnels. It has passed tests for "flammability, self-extinguishing properties, and the safety of emitted gases," making it suitable for use within tunnels. Additionally, the sheets are treated for high penetration and, when combined with a specialized adhesive, exhibit excellent adhesive performance. This helps to prevent the sheets from peeling during construction, ensuring safe installation. There are two types of sheets with different weaves: the "CR" type, primarily used for fall prevention, which incorporates carbon fibers woven in both vertical and horizontal directions, and the "UD" type, designed for reinforcement, which aligns carbon fibers in one direction. With the addition of the UD300, which has a weight of 300g/m², alongside the existing UD200 and CR200 (both with a weight of 200g/m²), the application range of the Gain CF Sheet Method has expanded.
