[Column] Three Types of Expansion Devices: Explanation of Features and Selection by Category

Introducing the types of expansion devices and explaining their features and benefits!

Expansion devices can be broadly divided into three types: by structure, by material, and by function. Each device has different characteristics, such as high shock absorption and ease of maintenance. Therefore, it is very important to understand the merits of each device in order to choose one that fits the environment of the bridge or road where it will be installed. This article introduces the types of expansion devices and explains their characteristics and advantages. By reading the article, you can get a general idea of what types of devices are available. *For detailed content of the column, please refer to the related links.

[Column] Structure of Bridges: Explanation of the Names and Roles of Each Component, and Types of Bridges

[Column] Structure of Bridges: Explanation of the Names and Roles of Each Component, and Types of Bridges

Explaining the structure of bridges and the names and roles of each component! Introducing types of bridges categorized by structure and materials.

A bridge is a structure built over rivers, valleys, seas, and roads, designed to provide a transportation route across to the opposite bank. Bridges have a long history of development alongside humanity, and today there are various types. Additionally, the characteristics of these bridges differ based on their structures, so construction must be tailored to the environment in which the bridge is installed. This article explains the structures and types of bridges. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

Bridge expansion device "N-FC Finger Joint"

Bridge expansion device "N-FC Finger Joint"

A structure designed with consideration for workability during regular inspections from below the bridge and when replacing water-stopping materials after it has been put into service!

The "N-FC Finger Joint" is a bridge expansion device that protects the water-stopping material, which is essential for non-drainage functionality, and prevents early deterioration of bridge girder ends in snowy and cold regions. By adding a fin cover to the underside of the face plate and narrowing the gaps of the comb teeth, the proportion of soil, snow, and ice that enters the gaps and reaches the water-stopping material can be reduced to below 15% even at the lowest temperatures (-20°C), thereby preventing the deterioration of the water-stopping material. Additionally, by using water-stopping materials that have passed tests based on NEXCO's construction management guidelines for structures, water-stopping performance is ensured. 【Features】 ■ Added fin cover to the underside of the face plate to narrow the gaps of the comb teeth ■ Resists constant wheel loads with only the face plate ■ Confirmed fatigue durability of over 50 years through fatigue tests using full-scale specimens ■ Utilizes water-stopping materials that have passed tests based on NEXCO's construction management guidelines for structures ■ Dry water-stopping materials, support brackets, and water-stopping rubber are designed to be detachable from below the girder *For more details, please refer to the PDF document or feel free to contact us.
