Expansion device "Metal Garge Joint NT-FFL type"
Providing cost performance with excellent mobility and low noise/low vibration! Horizontal (both sides) tooth structure/load support type.
The "Metal Garge Joint NT-FFL Type" is a product designed to ensure excellent mobility by having both the joint gap side and the post-poured concrete side shaped like teeth. It eliminates the weak points of welded structures by using stud welding for the anchor bar, and the face plate and web plate are made of a T-shaped integrated structure (shaped steel). The anchor components utilize reliable stud welding, achieving durability. The anchor components adopt a bar method with stud welding, making the installation of the floor slab anchorage easy. 【Features】 ■ Structural Characteristics... Double finger structure on both sides; load-supporting type/T-shaped integrated structure for the beam ■ Durability...
