Expansion Device Hybrid Joint [Construction Example Kanagawa Prefecture]
Hybrid Joint S-40
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.

Company information
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.
