![Aluminum Expansion Joint Cover [Sanpansion]](https://image.www.ipros.com/public/product/image/9fd/1372810006/IPROS_10010964099328000000.jpg?w=280&h=280)
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.
Introducing the features and differences of bridge expansion devices, including explanations of expansion devices by component and the three classifications of expansion devices!
There are various types of "expansion joints for bridges." Even when looking at the design drawings, some might say, "I don't really understand" or "Aren't they all the same?" At Expansion Joint Navi, we explain the features and differences of each type of bridge expansion joint and provide an introduction. For more details, please visit the related link page.

![[Column] What is a finger joint?](https://image.www.ipros.com/public/product/image/f63/2001472668/IPROS48131025019952884180.png?w=280&h=280)
Explaining the features based on three key points! It also summarizes aspects like appearance and structure.
A finger joint is one type of expansion device installed at the joints of bridges and highways. It is made of steel and is characterized by its comb-like appearance, and it is a device that has been used for a long time. In this article, we will explain the features of finger joints based on three key points. It summarizes basic knowledge such as appearance and structure, so by reading it, you will grasp the overall outline. *For detailed content of the column, you can view it through the related links.

Attention facility managers of school air conditioning systems. The "Reflex," compliant with the Ministry of Land, Infrastructure, Transport and Tourism's piping guidelines, is being increasingly adopted in public schools!
The installation of air conditioning systems in public elementary and junior high schools has become an urgent issue, and the government has announced the installation of air conditioning systems in all (public) elementary and junior high schools. The costs have been included in the government budget. Due to the low height and long horizontal layout of school buildings, expansion joints are often installed. This is because dividing the structure can minimize the damage the building receives from external forces such as earthquakes. The piping guidelines in the Ministry of Land, Infrastructure, Transport and Tourism's "Standard Specifications for Public Building Construction" mandate the use of flexible joints for piping that passes through expansion joints. As a result, the demand for Reflex, which complies with these piping guidelines and ensures the proper use of joints, has surged, and it is being increasingly adopted in public schools. [Please see our delivery records.] Additionally, Reflex is typically in stock, allowing for quick responses to urgent construction needs. *For more details about the product, please refer to the PDF materials or feel free to contact us.
