The Hybrid Joint CF type features a tooth-shaped design that smoothly transmits the movement of wheel loads on its surface, and its structure is designed to minimize noise and vibration by absorbing shocks from unevenness. The water-stopping structure, made of elastic sealing material and rubber, offers high water resistance, and since standard products are assembled and delivered at the factory for installation, the likelihood of water leakage from connection points is low. 【Features】 ○ High water resistance ○ Low noise for comfortable driving ○ Complies with NEXCO standards For more details, please contact us or request a catalog.

A bridge expansion device is something that is installed in the gaps (expansion gaps) between the bridge abutment and the bridge girder, or between bridge girders. When designing a bridge, it is necessary to provide expansion gaps to prevent the bridge girders from colliding with the bridge abutments or with each other due to thermal expansion and contraction caused by temperature changes. To cover these gaps and ensure safe passage for vehicles and pedestrians, a bridge expansion device is required. The role of the expansion device is to fill the gaps, but it is not sufficient to only fulfill that requirement. Consideration must also be given to the safe passage of vehicles and economic aspects, with specific functions including the following: 【Functions Generally Required of Expansion Devices】 - No noise during travel - No impact during travel - Long-term usability - No leakage under the girder - Simple construction - Easy and low-cost maintenance - Low cost of the device itself Our hybrid joint has eight major features that meet the required functions: - Compatible with small bridges to long-span bridges - Usable for all types of bridges - Ultra-low noise and comfortable travel - Long-term durability and maintenance-free - High water-tightness - Safe and easy construction - Replaceable - Economical

The "CF type" is a bridge expansion device that employs a waterproof structure using elastic seals. Its tooth-shaped design minimizes shocks during travel and reduces noise. Due to factory assembly, it allows for shorter construction time, improved ease of installation, and cost reduction. It is a product that complies with the NEXCO standards revised in July 2011. There is also a snow pressure-resistant product called the "NCF type." 【Features】 - High waterproof performance due to elastic seals - Low noise for comfortable travel - Reduced construction time - Cost reduction - Compliance with NEXCO standards - Basic specifications include a secondary waterproofing material attachment type For more details, please refer to the catalog. Feel free to contact us with any inquiries.

We are currently offering a comprehensive catalog (excerpt version) that clearly introduces the bridge expansion device "Hybrid Joint," which accommodates various types of bridges, for free. It is compatible with various bridge types, including steel bridges, PC bridges, RC bridges, as well as cable-stayed and curved bridges, featuring a high-performance waterproof structure that combines rubber and steel through press vulcanization bonding. Due to its small surface exposure, it generates less impact during vehicle passage, resulting in reduced noise and vibration. Its compact size allows for installation using a 4-ton unic crane, enabling safe, easy, and quick construction. 【Features】 ■ Compatible with various bridge types such as steel bridges, PC bridges, RC bridges, cable-stayed bridges, and curved bridges ■ Ultra-low noise and vibration-free ■ High waterproof performance ■ Long-term durability of 50 years ■ Ease of installation *For more details, please refer to the PDF document or feel free to contact us. *The PDF document is a digest version.
