Product Made in Japan
Manufacturer: Japan Life
Model: FCI

Product Features

● High corrosion resistance
The product made by high purity alumina ceramics that it will not get rust.
● High insulation
Since the insert itself is insulation property, even touch with steel bar in concrete, it will not get electic erosion.
● Resistance from fire
Will not change shape or deteriorate by 1,300degree high temperature. environment, safe even when there are fire disaster.
● High strength
Many tests prove the high strength not inferior to steel insert.
● Compatibility with concrete
Showing high compatibility with concrete since the material is high purity alumina ceramic and the thermal expansion coefficient is same with concrete.
■ Size of the bolt that can apply
For the thread for scafford insert, they are size in meter and inch, we will only use them in meter in order to avoid confusion.
This will apply to the bolts for scafford inserts.

■ Tensile strength for FCI insert (For calculation at JPCCA) (Unit：mm)

■ Design condition in the JPCCA’s insert construction manual
① Insertion depth will be defined by yield load of SS400 bolt, not by concrete corn breaking.

Concrete strength
Pa1 = φ1×√(FCK x 10.2)×3.14×Ｌ×(Ｌ+Ｄ)×0.098　φ1 = 1/3

Bolt strength
Pa2 = φ2×fys×As　φ2 = 2/3　fys = 240N/㎜²

Pa1 : Apply the 1/3 of concrete corn breaking load.
Pa2 : Apply the 2/3 of yield load of SS400 bolt. Pa1 >Pa2
② Screw thread supposed to be tightned 6 ridges, steel nut strength is more than 5T.
C: 6ridges of screw thread of FCI supposed to be tightened.
D: JIS B1052 steel nut strength is more than 5T. C > D
