Expansion Device Hybrid Joint [Construction Example, Kyoto Prefecture]

Expansion Device Hybrid Joint [Construction Example, Kyoto Prefecture]

We would like to introduce a case study of the hybrid joint (CF type) for bridge expansion devices, which excels in water resistance and durability.

Crittec Industries 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 condition of the removed existing expansion devices. 【Construction Example】 ○ Location: Kyoto Prefecture ○ Bridge Name: Asahi Elevated Bridge ○ Product: CF-80 and others ○ Comment: This is the installation of the NEXCO specification CF-80 type. The work was carried out with a complete road closure during concentrated construction. Measures were taken, such as preparing a tent, due to the forecast of rain.

Expansion Device Hybrid Joint [Construction Example Kanagawa Prefecture]

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. 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.

Checkpoints when installing expansion devices on steel floor slabs!

Checkpoints when installing expansion devices on steel floor slabs!

We will introduce in detail the points to be careful about when replacing the expansion device!

Have you ever had the experience of thinking about replacing an expansion device only to find that the bridge type was a steel deck? Steel decks have the advantages of being lighter in weight, having a lower structural height, and significantly shortening on-site construction time. However, there are points to be cautious about when replacing expansion devices. Expansion Device Navi provides detailed check points for installing expansion devices on steel decks. For more details, please refer to the related link page. [Contents] ■ Differences between steel decks and other types of decks ■ Expansion devices installed on steel decks ■ Methods for securing expansion devices to steel decks ■ Typical expansion devices ■ Summary *For more information, please refer to the related link page or feel free to contact us.

【Expansion Device】Ground Treatment of Expansion Devices - An Unexpected Pitfall!

【Expansion Device】Ground Treatment of Expansion Devices - An Unexpected Pitfall!

The water resistance greatly varies depending on the ground cover! A detailed explanation of the shapes and types of ground cover!

In the construction work for the ground cover section that needs to be done at both ends of the expansion joint, aesthetics tend to be emphasized, but the treatment of the ground cover section of the expansion joint is also a part that prevents the deterioration and leakage of the bridge. Since it doesn't appear much in cost estimation, many people may not have been very aware of it until now. At Expansion Joint Navi, we will explain about expansion joints and ground cover treatment. For more details, please refer to the related links.

[Column] Structure of Bridges: Explanation of the Names and Roles of Each Component, and Types of Bridges

Explaining the structure of bridges and the names and roles of each component! Introducing types of bridges categorized by structure and materials.

A bridge is a structure built over rivers, valleys, seas, and roads, designed to provide a transportation route across to the opposite bank. Bridges have a long history of development alongside humanity, and today there are various types. Additionally, the characteristics of these bridges differ based on their structures, so construction must be tailored to the environment in which the bridge is installed. This article explains the structures and types of bridges. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

[Column] What is a buried expansion device?

[Column] What is a buried expansion device?

Explaining the four benefits, construction methods, and types! Also introducing the manufacturers that produce them.

Buried expansion devices, unlike other joints, are not visible from the road. Since they are embedded in the pavement, they are integrated with the road, resulting in minimal noise and vibration. Additionally, maintenance is relatively easy, and over the long term, costs can be significantly reduced. As a result, they are increasingly being installed in small to medium-sized bridges. This article explains the features and benefits of buried expansion devices. We will also introduce the manufacturers producing them, so you can grasp all the details. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*
