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 [Construction Example Kanagawa Prefecture]

Expansion Device Hybrid Joint [Construction Example Kanagawa Prefecture]

We will introduce examples of the construction of hybrid joints (NS to LL type) for bridges, which excel in water resistance and durability.

Critic Co., Ltd. not only sells products but also often takes responsibility for installation work, striving to improve products by considering issues that arise during installation and the condition of damaged existing expansion joints that have been removed. 【Construction Case】 ○ Location: Kanagawa Prefecture ○ Bridge Name: Otake Bridge ○ Product: S-40 and others ○ Comments: The existing joint was of the slide type, and the replacement was carried out after painting and paving had already been completed. The thickness of the deck slab is approximately 200mm, so care was taken not to remove the slab during chipping and excavation, as well as during the installation of reinforcing anchors, and protective measures were taken to avoid damaging the pavement and paint. Additionally, since it is a living road used for commuting and walking, restrictions were implemented with the assistance of guides for partial regulation. For more details, please contact us or request a catalog.
