"K-40" is a diamond-free joint developed by our company based on numerous experiences for horizontal joints. It features a separation structure consisting of a receiving base installed on the floor slab, a receiving plate placed on top of the receiving base, and a surface rubber with numerous diamond-shaped holes. Despite being separate components, they function as a cohesive unit, demonstrating excellent performance. Both the product and installation possess flexible performance, making it widely used in many highways, bridges, and elevated bridges. [Features] ■ Protects the floor slab ■ Comfortable driving ■ Safe driving ■ Environmentally friendly ■ Cost-saving *For more details, please download the PDF or feel free to contact us.
We can accommodate both pre-installed and post-installed methods for various types of bridges, including RC bridges, PC bridges, and steel bridges!
The "K-210T" is a diamond-free joint designed for vertical joints that can accommodate large displacement amounts caused by longer span lengths. The surface rubber has sufficient thickness, and the load-bearing plate is coated with rubber on a steel plate, which helps to mitigate impact loads and reduces the effects on the floor slab. Additionally, the surface rubber absorbs expansion and contraction through the elastic deformation of diamond-shaped holes, keeping the joint surface consistently flat, resulting in reduced noise during travel and a more comfortable ride. 【Features】 ■ Protects the floor slab ■ Comfortable travel ■ Safe travel ■ Environmentally friendly ■ Cost-saving *For more details, please download the PDF or feel free to contact us.
Rubber joint that can also be used for wide play areas! It can be used for vertical joints as well.
We would like to introduce the pedestrian joint "I-30" handled by Nihon Bridge Engineering Co., Ltd. This product is made of rubber and can accommodate wide gaps, and it can also be used for vertical joints. Additionally, we handle road joints, offering a variety of horizontal and vertical joints. Please feel free to contact us if you have any requests. 【Features】 ■ Made of rubber, suitable for wide gaps ■ Usable for vertical joints *For more details, please download the PDF or feel free to contact us.
Buried Seamless Joint SJ-M Type
This is a construction method that aims to achieve continuous paving of expansion joints using the highly durable elastic pavement material "Falcon SJ." The exposed Falcon SJ has properties equivalent to the preceding and following asphalt pavements, ensuring that no bumps occur over a long period of use. 【Features】 ○ Compatible with both horizontal and vertical joints ○ Complies with pavement gradients ● For other functions and details, please contact us.
Drainage and high-performance pavement compatible seamless joint SJ-MD type
This is a construction method that accommodates drainage and high-performance pavement. It uses open-graded aggregate in the surface layer that flexibly follows deflection and expansion, allowing for continuous drainage on the bridge deck at expansion joints. 【Features】 ○ Compatible with both horizontal and vertical joints ○ Compliant with pavement slope ● For other functions and details, please contact us.
Completely buried seamless joint SJ-P type
This is a method that is completely buried under asphalt pavement. It provides a driving experience that feels completely natural for short-span, small-scale bridges. 【Features】 ○ Compatible with both horizontal and vertical joints ○ Complies with pavement slope ● For other functions and details, please contact us.
Two-stage coupling HQ joint
Two-stage coupling HQ joint 【Features】 ○ Two additional vibration-damping ribs have been added to the lower joint with an extended effective length. ○ In addition to floor drainage toilets (S type), it can be easily connected to multiple floor-mounted drainage toilets (P type) with different toilet center heights. ● For other functions and details, please contact us.

EXP.JC, which corresponds to various displacements and has smooth fitting.
The expansion joint ensures smooth and secure fitting of each component (main cover and fixing hardware, etc.), flexibly responds to various displacements, and demonstrates the functionality of the expansion joint.
By emphasizing mobility performance, it is possible to follow displacements in all horizontal directions.
The "Sanpansion R Type" is designed not only for uniaxial movement but also to accommodate simultaneous XY movement, making it capable of responding to complex horizontal movements similar to actual seismic activity. In terms of horizontal displacement, as long as the displacement is within the range of motion, it can follow without damage or deformation, allowing for continuous use. 【Features】 ■ Emphasis on mobility performance ■ Standard product of Sanpansion ■ Capable of following in all horizontal directions without damage or deformation *For more details, please refer to the PDF document or feel free to contact us.
Bridge expansion device that achieves high water stop, ultra-low noise, and comfortable travel, designed with consideration for the surrounding environment of the bridge [NETIS registered product].
The hybrid joint is a non-drainage expansion device developed using a composite technology of rubber and steel, achieving very high water-stopping performance by press vulcanizing and bonding steel plates and rubber. Additionally, by adopting a steel vertical shape for the load-bearing structure, the surface exposure area is minimized, enhancing sound insulation and durability. The range of products available includes both small and large items, capable of accommodating expansion amounts from 20mm to 175mm and a maximum slab gap of 395mm. 【Features】 ○ High water-stopping performance ○ Steel vertical tooth shape ○ One-lane assembly product For more details, please contact us or request a catalog.
![Expansion Device Hybrid Joint [Construction Example Tokyo No. 1]](https://image.www.ipros.com/public/product/image/f40/2000262537/IPROS980960628852465201.jpg?w=280&h=280)
We would like to introduce examples of construction for hybrid joints (NS to LL type) for bridges, which excel in water resistance and durability.
Crittec Co., Ltd. not only sells products but often takes responsibility for installation work as well, striving to improve products by considering issues that arise during installation and the condition of removed existing expansion devices. 【Construction Case】 - Location: Tokyo - Bridge Name: Suijin Ohashi Elevated Bridge - Products: NS-20 and others - Comments: Prime contractor work. Noise reduction sheets were installed, and noise control measures were implemented. CS-50 (single-sided steel deck type) was also used. For more details, please contact us or request a catalog.
Bridge expansion device proven to last 100 years! No replacement needed for new bridges for 100 years! Long-term water-tightness, maintenance-free [NEXCO specification compliant product].
The Hybrid Joint 3LII type has a vertical integrated structure of the load support plate and anchor plate, which provides high durability and prevents damage from metal fatigue. Its durability is ultra-long-term, lasting 100 years! It has been proven through fatigue loading tests conducted by a third-party organization, successfully clearing the equivalent of 12 million cycles, which corresponds to 100 years. This assumes that a 25-ton large vehicle has traveled over the 3LII type 12 million times, equating to a 100-year durability. The standard design supply period for bridges is 100 years. For newly constructed bridges, there is no need to replace the expansion devices for 100 years. The 3LII type is maintenance-free, eliminating the need for traffic regulation during sound inspections, leading to reduced maintenance costs and improved safety. It is a product capable of accommodating large expansion amounts (150–350mm) and wide gaps (up to 730mm), making it one of the largest among expansion devices that have passed NEXCO standards. It has been widely adopted on highways across the country as a product that meets NEXCO specifications. For more details, please contact us or request a catalog.
