Anchor Systems
anchor system with convenient maintenance
With the existing anchor system, the size of anchor bolts becomes larger as the horizontal forces are increased which causes a phenomenon in which the anchor bolts fall off during maintenance. Which is why it was necessary to develop an anchor system with convenient maintenance.
Existing anchor systems
| configuration | function |
|---|---|
|
|
- The size of anchor bolts become larger as the horizontal force increases
- As the anchor bolts becomes larger, they can fall off during maintenance
Anchor system with convenient maintenance
(MFA : Maintenance Free Anchor)
| configuration | function |
|---|---|
|
|
- Shear resistance of the horizontal force shouldered by bolts at the shear key
- Use of minimum-specification bolts with lengths that are short, making maintenance easier
Anchor system with convenient maintenance(MFA with Uplift Pin)
| configuration | Function |
|---|---|
|
|
- Shear resistance of the horizontal force shouldered by bolts at the shear key
- Use of minimum-specification bolts with lengths that are short, making maintenance easier
- Use of an uplift pin capable of resisting the uplift force
Anchor system with convenient maintenance (New MFA)
| configuration | function and maintenance methods |
|---|---|
|
|
- Shear resistance of the horizontal force shouldered by bolts at the shear key
- Shear key falls below when bolts are removed and, thus,
the lifting of the upper structure is minimized during replacement
