Expansion Device Hybrid Joint [Construction Example Aomori Prefecture]

We would like to introduce a case study of the hybrid joint (Type 3L), a bridge expansion device that excels in water resistance and durability.

Crittec Industrial Co., Ltd. not only sells products but often takes full responsibility for installation work as well. We strive to improve our products by considering the issues that arise during installation and the damage conditions of the removed existing expansion devices. 【Construction Example】 - Location: Aomori Prefecture - Bridge Name: Nozomi Bridge - Product: 3L-250 - Comment: Since vehicles could not access the bridge, we performed the installation by lifting it with a crane from underneath the bridge. For more details, please contact us or request a catalog.

CRETEC, a company under Crittec Industries, was born from the combination of Create (creation) and Technology. As a comprehensive manufacturer of bridge expansion devices, we continue to develop expansion devices that contribute to the longevity of bridges and environmental protection. Moreover, we do not stop at product manufacturing; by consistently handling everything from research, design, manufacturing, sales, to construction in-house, we can manufacture and install expansion devices that meet the requests of our clients and general contractors, as well as the conditions and environments of the bridges and roads on-site. We also take into account the issues that arise during the installation of expansion devices and the damage conditions of existing devices that are removed, using this information to improve and develop our products. Please feel free to contact us for inquiries about bridge expansion devices, requests for materials, or estimates. ◆ What is a bridge expansion device? It is a component installed in the gap between the bridge abutment and the bridge girder, or between bridge girders. When designing a bridge, it is necessary to create a gap to prevent the bridge girders from colliding due to expansion and contraction caused by temperature changes. The bridge expansion device is required to cover this gap and ensure safe passage for vehicles and pedestrians.
