[Column] Replacement of Expansion Devices: Explanation of the Procedure and Three Important Points to Note

[Column] Replacement of Expansion Devices: Explanation of the Procedure and Three Important Points to Note

Explaining the differences between replacing and newly installing a telescopic device! Summarized the flow and key points related to replacement.

The replacement of expansion joints requires thorough on-site investigation and construction tailored to the situation. Since the construction time is limited to one day, schedule management is also very important. Additionally, there are many points to consider that differ from new installations, such as the height of the installation and the area of concrete removal. This article summarizes the flow and key points related to the replacement of expansion joints. Please refer to it as preliminary knowledge before the construction. *For detailed content of the column, you can view it through the related links.

[Column] Drainage and Non-Drainage Expansion Devices

[Column] Drainage and Non-Drainage Expansion Devices

Explanation of the differences and devices for enhancement! I have also summarized the mechanisms for enhancing the functions of the devices.

The expansion and contraction devices can be broadly divided into drainage type and non-drainage type. When these devices first started being installed, the drainage type was used, but over time, the non-drainage type has become the mainstream. The difference between the two lies in whether or not water leakage measures are implemented. However, due to the infrastructure development policies set by the government, most manufacturers have started producing non-drainage types. This article introduces the differences between drainage and non-drainage types as well as their usage ratios. Additionally, we have summarized the mechanisms that enhance the functions of the devices, so please refer to that as well. *For detailed content of the column, you can view it through the related links.
