What is the difference between a planted bar and an anchor bolt?

Meaning

Reinforcement: one of the post-anchor connection methods in which ribbed steel bars or full-threaded rods are fixed in the base concrete with specific structural glue.

2. Anchor Bolt: The anchor bolt component product that fixes the connected part to the base material, which is divided into mechanical type and chemical type. Mechanical anchor bolt is a kind of anchor bolt formed by the friction between anchor bolt and anchor hole or locking key. According to its working principle, it can be divided into: expanded bottom anchor bolt and expansion anchor bolt; chemical anchor bolt is made of metal screw It is composed of an anchoring glue, and an anchoring bolt is formed through the anchoring glue. Chemical anchors are divided into ordinary chemical anchors and special inverted cone-shaped chemical anchors.

Application object

1. Reinforcement technology is suitable for reinforced concrete structures, but not suitable for plain concrete structures and low reinforcement ratios; the reinforcement ratio of longitudinally stressed steel bars cannot be lower than the current national standard GB50010 "Specification for Design of Concrete Structures" Lower limit of reinforcement rate.

In the concrete structure of the anchor rod after planting the bars, hot-rolled ribbed steel bars should be used instead of aperture steel bars. The relative rib area of different ribs will also have some influence on the load-bearing capacity of the implanted bar.

When the rear anchor member is steel threaded, a fully threaded screw should be used instead of a screw with no thread at the anchoring part.

2. The anchor anchor base material can be reinforced concrete, prestressed concrete or concrete members. Freezing-damaged concrete, corroded concrete, severely cracked concrete, and uncompacted concrete cannot be used as anchoring substrates.

Install margins and spacing.

1. The small spacing s and small margin c of the group anchor bolts are determined according to the identification report of the anchor bolt product; if there is no identification report, the following table shall be implemented. The small margin c of the anchor should not be less than 2 times the size of the large aggregate;

The distance between the planting bar and the edge of the concrete should not be less than 5 cm and not less than 100 mm. When there is a transverse steel bar perpendicular to the direction of the planting bar between the planting bar and the edge of the concrete, the small distance between the planting bar and the edge can be appropriately reduced, but it should not be less than 50mm, and the small distance between the planting bar and the edge of the concrete should not be less than Image or the like Measure the cross-sectional area. The interval between planting bars cannot be less than 5 days. d is the diameter of the steel bar.
