In the beam reinforcement, the U-shaped steel plate hoop shall not exceed the bottom of the floor.

The width of the U-shaped hoop should not be less than 2/3 of the width of the reinforced fiber composite material and should not be less than 200mm；; The intermediate hoop should not be less than 1/2 of the width of the reinforced fiber composite material and should not be less than100 mm.

Narrow bonded steel and block bonded steel are named according to their shapes. The shape depends on the beam-shaped narrow reinforced beam bottom steel plate, which strengthens the beam bottom steel plate and blocks the steel plate.

The ring plate is anchored to the side of the beam by fixing the beam surface steel plate in the form of U-shaped ring plate.

The bottom of the beam is generally made of narrow bonded steel (a strip steel plate with a thickness of more than 0.5 300mm), and the holes are generally bonded with massive steel bars. For example, in www.jzjiagugs.com, the hoop plate at the bottom of the plate is used for steel bar bonding, and both sides of the beam are used (with stirrups).
