Introduce the characteristics, classification and installation methods of the rear-expanded anchor bolts. The following small-scale expansion anchor bolt manufacturers are introduced to you:

The rear reaming type anchor refers to re-reaping the hole at the bottom of the hole after the straight hole of the concrete substrate is finished. The cavity after the reaming and the key piece opened by the anchor form an interlocking mechanism to realize the rear anchor connection. In GB50367-2013 "Construction Concrete Structure Reinforcement Design Code", the lock anchors that define such structures are collectively referred to as rear expansion anchors.

product features:

Anchored to cracked concrete for the highest safety requirements, resistant to shock and impact loads.

It has a very high load carrying capacity and the anchoring effect is comparable to that of the embedded part.

The smaller torque can be carried by the screw, and the built-in mechanical lock effect.

Adapt to variable anchor depth and variable fixture thickness.

No expansion stress, low initial stress applied to the concrete substrate, suitable for small margins and small spacing.

Features:

1. It has extremely high load carrying capacity, anti-fatigue, anti-vibration, safe and reliable.

2. The expansion stress is small, suitable for installation and fixing of small margins and small distances.

3. It is suitable for all special environments where it is not suitable for planting or not using chemical anchors.

4. The anchor bolt has obvious installation scale and is easy to install.

5. According to different use environments, there are different materials to meet the various needs of customers.

6. Variety of specifications, can also be customized according to the requirements of the construction of a variety of special specifications of the product.

7. The post-expansion mechanical anchor has a special reaming drill bit, which can be quickly reamed and installed quickly.
