What is a bridge expansion device? Features of hybrid joints (Free materials available)

What is a bridge expansion device? Features of hybrid joints (Free materials available)

What is an expansion device? The roles and required functions in bridges and highways - 8 major features that hybrid joints fulfill.

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

Expansion device "Hybrid Joint"

Expansion device "Hybrid Joint"

[NETIS Registered Product] A bridge expansion device with high water stop performance, comfortable driving, and ultra-low noise.

This is a bridge expansion device adopted nationwide, primarily by the Ministry of Land, Infrastructure, Transport and Tourism, NEXCO, urban expressways, local governments, and other public organizations. 【Features (excerpt)】 ◆ Compatible with small to large bridges Handles expansion amounts from 20mm to 600mm, with a maximum gap of 1230mm. Other specifications can be designed separately. ◆ Usable for all types of bridges Can be used for all types of bridges, including steel bridges, PC bridges, RC bridges, as well as arch bridges and curved bridges. ◆ High water-tightness "NS-LL type": The steel plate and sealing rubber are bonded using a mold (press vulcanization bonding), preventing separation between the steel plate and rubber. ◆ Safe and easy installation Can be installed using a 4-ton unic crane without the need for large machinery like medium to large rough terrain cranes, allowing for safe and easy (speed-up) construction. Here’s a brief introduction to some installation examples! ~~ At the Tochigi Prefecture Nikko Civil Engineering Office (Maruyama Bridge), a "Hybrid Joint" was used for renovation work. * NS-LL type repair ~~ At the Kinki Regional Development Bureau Kinokawa River National Road Office (Takasegawa Bridge), it was used for a newly constructed bridge. * 3L type For more details, please contact us or download the catalog.
