Strand sheet reinforcement method

This is a groundbreaking method that fundamentally solves the problems of sheet swelling and defects associated with conventional continuous fiber sheet bonding techniques.

This technology involves processing FRP strands that have been impregnated and cured with resin into sheets, which are then adhered to the surface of concrete structures using a specialized adhesive for repair and reinforcement methods. It can be applied to reinforcement measures for cantilever slabs in concrete bridge decks and the upper parts of main girders. Additionally, it can be used for concrete slabs that suffer from insufficient strength due to floor slab improvements or the increased size of loading vehicles corresponding to the year of bridge construction. The effectiveness of this method increases particularly in areas with heavy traffic where road restrictions occur. 【Features】 ■ Immediate sheet application after surface preparation ■ Excellent workability without the need for resin impregnation or degassing ■ Short construction period and cost-effective ■ Simple and high quality ■ Significant reinforcement effect *For more details, please refer to the PDF materials or feel free to contact us.

Concrete repair and reinforcement method "CFRP Laminate Method"

Streamlining of work is achievable! Repair and reinforcement methods for reinforced concrete structures using CFRP.

The "CFRP Laminate Method" is a reinforcement technique that involves arranging carbon fibers in one direction, impregnating them with epoxy resin, and shaping and curing them into a plate-like form. This CFRP is then adhered to the concrete surface using a paste-like epoxy adhesive (Sika Dur 30), making the process simple. Since the surface preparation is only required for the area to be adhered, it also takes into account the preservation of the working environment and the reduction of waste. 【Features】 - Easy to work with, requiring no large machinery or equipment - Can be performed in areas where pipes intersect beneath the slab or in confined spaces - Reduces safety risks for workers and minimizes protective measures around the work area - There is almost no change in the shape or weight of the reinforced members - Provides reinforcement equivalent to 4 to 8 layers of carbon fiber sheets, allowing for labor-saving in the work process *Available in Tokyo, Saitama, Chiba, and Kanagawa Prefectures *For more details, please refer to the PDF materials or feel free to contact us.

Reinforcement of Existing Concrete Structures: Outplate Method

High bending reinforcement effect and high crack control effect! Suitable for the construction of RC and PC hollow slab bridges.

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

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.

Anti-fall prevention method "Hybrid Sheet Method"

NEXCO Structural Construction Management Guidelines: Obtaining Proof of Spalling Prevention Performance! Introducing an excellent construction method that also leads to shortened construction periods.

The "Hybrid Sheet Method" is a construction technique that involves adhering a weather-resistant "HB Sheet (Hybrid Sheet)" to the surface of concrete using adhesive. Similar to concrete protective coatings, it possesses the ability to suppress salt damage and carbonation, providing measures against deterioration (salt damage and carbonation). Since it can be reinforced by simply overlapping without removal, the initial construction will not be wasted when reinforcing with steel plates or CFRP in the future. Additionally, compared to conventional methods, the number of traffic regulation days is reduced by about half, leading to a shortened construction period. 【Features】 ■ Excellent peeling prevention performance ■ Contributes to shortening the construction period ■ Measures against deterioration (salt damage and carbonation) are also possible ■ Can be reinforced by overlapping without removal ■ Obtained certification for peeling prevention performance according to NEXCO structure construction management guidelines *For more details, please refer to the PDF document or feel free to contact us.
