Expansion Device 【Hybrid Joint】 Construction Example Yamagata Prefecture

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 Industries Co., Ltd. not only sells products but often takes responsibility for installation work as well. We strive to improve our products by considering the issues that arise during installation and the condition of the removed existing expansion joints. 【Construction Case】 ○ Location: Yamagata Prefecture ○ Bridge Name: Haguro Bridge ○ Product: L-70 and others ○ Comment: Since this is a snow-covered area, we covered the joint with a blue tarp for curing in preparation for concrete pouring the next day. For more details, please contact us or request a catalog.

Expandable device [Hybrid Joint] 3LIIA type

[NETIS Registered Product] Supports large expansion (200-600mm) and wide spacing (up to 1230mm). Contributes to the longevity of bridges and reduces lifecycle costs.

The Hybrid Joint 3LIIA type has a vertical integrated structure for the load support and anchor plate sections, making it highly durable and preventing damage from metal fatigue. A fatigue loading test conducted using actual products by a third-party organization confirmed a service life of 100 years, demonstrating durability for 100 years. This 100-year durability aligns with the design service life of bridges. Unlike conventional products that require replacement of expansion devices 3 to 4 times, this product can be used without any replacements, significantly reducing lifecycle costs. By using steel plates vertically, the exposed parts are minimized, resulting in very low impact during operation, and making it less likely to generate noise and vibration. It is a product capable of accommodating large expansion and wide spans, and it is one of the largest products in the category of rubber-based joints (a general term for products other than finger joints and embedded joints). The main differences from the NEXCO specification 3LII type are that the secondary waterproofing material is not standard equipment (but can be installed separately) and that the painting specifications differ. The durability and the waterproof structure of the main body are equivalent to the NEXCO specifications.

Expandable device "Metal Top Super Joint MTS Type"

Horizontal (one-sided) tooth profile structure / butt joint type! A long seller due to versatility and cost-effectiveness.

The "Metal Top Super Joint MTS Type" is an expansion device for bridges and elevated roads that has undergone anti-corrosion treatment through hot-dip galvanization on the entire surface of the main body. The use of a tooth profile instead of a straight line at the tire contact point during joint passage improves drivability. The adoption of seamless P.K.G. prevents water leakage and the dropping of soil. Since it is detachable, the main body can be replaced easily, making repairs straightforward. 【Features】 ■ Structural characteristics ■ Durability ■ Workability ■ Drivability ■ Water-stopping ability ■ Repairability *For more details, please download the PDF or feel free to contact us.
