[Column] What is an expansion device? Explaining its role in bridges and highways.

[Column] What is an expansion device? Explaining its role in bridges and highways.

We are explaining what role the expansion and contraction device plays!

An expansion joint is a device used to fill the gaps found in bridges and highways. If there are gaps in a bridge, it can cause issues when vehicles pass over it, so these joints are installed to cover the gaps and allow for a comfortable passage. However, although they are referred to as coverings, they are not simply metal plates that cover the gaps. There are other roles that an expansion joint is required to fulfill, and manufacturers produce and handle products that meet the necessary quality and functionality. This article explains the roles that expansion joints play. It also summarizes the types of expansion joints and manufacturers, so by reading it, you should gain a general understanding of the topic. *For detailed information, please refer to the related links. Feel free to contact us for more information.*

Expansion device "NLH/NTH/DFH type" cold region compatible type, for Hokkaido.

Expansion device "NLH/NTH/DFH type" cold region compatible type, for Hokkaido.

Investigating the causes of deterioration and damage to expansion devices in cold snowy regions! Development aimed at extending lifespan and achieving high LCC evaluation.

Our company has investigated the current state of damage to expansion joints in snowy and cold regions, focusing on the causes of damage and their characteristics, and has developed cold-region-compatible expansion joints. We have established a dust-proof layer in the device's gap section to prevent clogging by soil and debris, and installed internal steel plates beneath the dust-proof layer to resist the compressive forces of packed snow, thereby protecting the waterproof layer. In addition to the built-in temporary waterproofing material, we have standardly equipped the device with secondary waterproofing material aimed at long-term waterproofing, ensuring a structure that does not cause water leakage. 【Features】 ■ Anti-corrosion treatment... To prevent corrosion of steel materials due to freezing agents and rainwater, a high corrosion-resistant treatment of "aluminum-magnesium alloy thermal spraying" has been applied to the entire surface of the steel. ■ Protection of waterproofing material... A dust-proof layer has been established in the gap section of the expansion joint to prevent clogging by soil and debris, and internal steel plates have been installed beneath the dust-proof layer to resist the compressive forces of packed snow, thereby protecting the waterproof layer. Additionally, in conjunction with the built-in primary waterproofing material, we have standardly equipped the device with secondary waterproofing material aimed at long-term waterproofing, ensuring a structure that does not cause water leakage. ■ Snow removal measures... A snow plow guide plate compliant with the specifications of the Hokkaido Development Bureau has been installed. *For more details, please download the PDF or feel free to contact us.
