The embedded channel is a groove device embedded in reinforced  concrete, which is firmly combined with the concrete by anchor rod. When  installing, the head of T-bolt is inserted into the channel and rotated 90  degrees to fasten the components to be installed on the channel through  T-bolt. 

The embedded channel is riveted by channel and anchor rod, and the  material is Q235B. It is widely used in subway, pipe gallery, super high-rise  building and other large-scale construction projects.

Channel type

Square channel shape (R1 ~ R2)                     The shape of the alveolar canal (Z1, Z2, Z3)

Hot rolled steel grooves (R1, R2)

Hot rolled from a full-size billet;

No internal stress;

The best geometry with an enhanced notch ensures a high tightening torque;

Suitable for dynamic load;

It has good fatigue resistance even under the highest working load;

It is verified by blasting and impact limit load.

Hot rolled grooves with teeth (Z1, Z2, Z3).

It has an all-round (longitudinal) bearing capacity of steel grooves;

The toothed steel groove has passed the German construction technology certification (Zmur21.4-1690).

Channel characteristics and advantages:

(1) the pre-buried channel can be strengthened in the segment or lining of the tunnel.

(2) the pre-buried channel is subjected to an overall force, not a single point, and the force is uniform and can withstand dynamic fatigue load.

(3) the pre-buried channel has passed the fire resistance test certification, the bearing capacity change is small and the fire resistance grade is high when the fire is high temperature.

(4) the pre-embedded channel ensures the installation accuracy of the fixed frame and the convenient adjustment of the ring direction.

(5) T-shaped bolts are fixed without welding and easy to install.

(6) No drilling is required and reinforced concrete structures are not damaged.

(7) using prefabricated design components to reduce construction time.

(8) it can be installed in the tension and compression area of concrete.

(9) the pre-buried channel is an advanced technology of international high-speed railway, which is safe, noise-free and vibration-free, and can meet different needs.
