Expansion device "Hinodakutairu Joint α (for sidewalks)"

Expansion device "Hinodakutairu Joint α (for sidewalks)"

Freely choose surface materials to match the surrounding landscape! A durable and aesthetically pleasing expansion device.

The "Hinodakutairu Joint α (for sidewalks)" is a sidewalk expansion joint that allows for the free selection of surface materials to match the surrounding landscape. One of the challenges with sidewalk expansion joints has been that post-installed concrete does not blend well with the surrounding asphalt pavement or colored tiles. This product allows for the selection of pavement surfaces that match the landscape of the installation site, and because it can fill the surface material up to the vicinity of the expansion joint, it enables construction with excellent aesthetic quality. 【Features】 ■ Allows for the selection of pavement surfaces that match the landscape of the installation site ■ Ensures water-tight performance similar to that of roadway expansion joints *For more details, please refer to the catalog. Feel free to contact us with any inquiries.

Expansion Device Hybrid Joint [Construction Example, Yamagata Prefecture]

Expansion Device Hybrid Joint [Construction Example, Yamagata Prefecture]

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

Crittec Industrial Co., Ltd. not only sells products but often takes responsibility for installation work as well. We strive to improve our products by considering issues that arise during installation and the condition of existing expansion joints that are removed. 【Construction Case】 - Location: Yamagata Prefecture - Bridge Name: Haguro Bridge - Product: L-70 and others - Comment: Since it is an area with heavy snowfall, 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"

Expandable device "Hybrid Joint 3LIIA Type"

[NETIS Registered Product] Supports large expansion and contraction (200–600mm) and wide spacing (up to 1230mm). Expansion device for bridges designed with consideration for the surrounding environment.

The Hybrid Joint 3LIIA type, like the conventional Hybrid Joint 3L type, has a vertical integrated structure for the load support and anchor plate sections, resulting in high durability with almost no damage from metal fatigue. By using steel plates vertically, the exposed parts are minimized, leading to very low impact during operation, and making the product less prone to noise and vibration. It is capable of accommodating large expansion and contraction (200–600mm) and wide gaps (up to 1230mm), making it 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 water stop material is not standard equipment (but can be installed separately) and that the painting specifications differ. The durability and water stop structure of the main body are equivalent to the NEXCO specifications. 【Features】 ○ Accommodates large expansion and contraction and wide gaps ○ High water stop performance due to the zipper structure ○ Long-term durability and maintenance-free For more details, please contact us or request a catalog.
