What is a bridge expansion device? Features of hybrid joints [Free materials available]

What is a bridge expansion device? Features of hybrid joints [Free materials available]

What is an expansion device? The roles and required functions in bridges and highways - The eight major features that hybrid joints fulfill.

A bridge expansion device is something that is installed in the gaps (expansion gaps) between the bridge abutment and the bridge girder, or between bridge girders. When designing a bridge, it is necessary to create expansion gaps to prevent the bridge girders from colliding with the bridge abutments or with each other due to thermal expansion and contraction. To cover these gaps and ensure safe passage for vehicles and pedestrians, a bridge expansion device is required. The role of the expansion device is to fill the gaps, but it is not sufficient for it to only fulfill that function. Consideration must be given to the safe passage of vehicles and economic aspects, and specifically, the following functions are highlighted: [Functions Generally Required of Expansion Devices] - No noise during travel - No impact during travel - Long-term usability - No leakage under the girder - Easy installation - Simple and cost-effective maintenance - Low cost of the device itself Our hybrid joint has eight major features that meet the required functions: - Compatible with small bridges to long-span bridges - Usable for all types of bridges - Ultra-low noise and comfortable travel - Long-term durability and maintenance-free - High water-tightness - Safe and easy installation - Replaceable - Economical

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.

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.

[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.*

Bridge expansion device "N-FC Finger Joint"

Bridge expansion device "N-FC Finger Joint"

A structure designed with consideration for workability during regular inspections from below the bridge and when replacing water-stopping materials after it has been put into service!

The "N-FC Finger Joint" is a bridge expansion device that protects the water-stopping material, which is essential for non-drainage functionality, and prevents early deterioration of bridge girder ends in snowy and cold regions. By adding a fin cover to the underside of the face plate and narrowing the gaps of the comb teeth, the proportion of soil, snow, and ice that enters the gaps and reaches the water-stopping material can be reduced to below 15% even at the lowest temperatures (-20°C), thereby preventing the deterioration of the water-stopping material. Additionally, by using water-stopping materials that have passed tests based on NEXCO's construction management guidelines for structures, water-stopping performance is ensured. 【Features】 ■ Added fin cover to the underside of the face plate to narrow the gaps of the comb teeth ■ Resists constant wheel loads with only the face plate ■ Confirmed fatigue durability of over 50 years through fatigue tests using full-scale specimens ■ Utilizes water-stopping materials that have passed tests based on NEXCO's construction management guidelines for structures ■ Dry water-stopping materials, support brackets, and water-stopping rubber are designed to be detachable from below the girder *For more details, please refer to the PDF document or feel free to contact us.

Marking Service

Redraw the lane markings so that the route is clear! For a road that is easier for drivers to navigate.

We would like to introduce the lane markings developed by Hanshin Road Development Co., Ltd. On road surfaces that have aged and have poor drainage, or where unevenness has developed, the behavior of vehicles can suddenly become erratic, which is very dangerous. By repaving the road to allow drivers to operate without stress and by repainting the lane markings to clearly indicate the path, we can create roads that are easy to use for both drivers and pedestrians. 【Other Services Offered】 ■ Bridge repair work ■ Road sign installation ■ Guardrail installation ■ Sound barrier construction *For more details, please refer to the PDF document or feel free to contact us.
