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.
