Implementing Roll-bolt, the first step in every support system implementation

Roll-bolt - Anchor bolt

Implementing roll-bolt is the first step in implementing every support system that at the same time, it requires high technical skills. The least mistake in installing the bolt roll will cause irreparable damage.

Roll-bolts divide into two categories:

• Mechanical
• Chemical

Here is a brief explanation about mechanical roll- bolts:

The first step in selecting roll-bolt is type of the ceiling and the concrete class in which the roll bolt is supposed to be installed

Next, the amount of force (tension and shear) that this roll bolt is supposed to tolerate must be considered by the designer.

Tolerating the seismic loads is another point that is considered by some designers.

In addition, the resistance of the roll-bolt against fire is another parameter in choosing the roll-bolt.

Special attention should be paid to the following points when designing and installing the roll-bolt:

• Installing distance of two roll-bolts from each other
• Installing distance of roll-bolt from edge of the concrete
• Required torque for roll-bolt activation
• Planting depth of the roll-bolt
