Anchor bolts are used to connect various parts such as metal plates, concrete, etc., to roofs, floors or concrete walls, to strengthen building structures, to install consoles and to create floors, and many other things.
These products are available in two general types, including mechanical anchor bolts and chemical anchors. Anchor bolts must be strong enough to be used for their specific use and have sufficient resistance to physical, chemical and corrosion damage.
There are several factors to consider when designing anchor bolts.
1- Load extension or direction: Since the task of the anchor bolt is to withstand the load, so the direction of the applied force must be clear.
2- Type of load: Naturally, static and motionless load is very different from dynamic and moving load.
3- Identical load distribution between anchor bolts: If a set of anchor bolts have fixed a piece, the load on some of them may be higher due to lack of proper design or execution.
4- Load on the concrete structure: The sum of static and dynamic loads on the structure on which the anchor bolt is installed is effective in the design and execution of the anchor bolt.
5- Distance of anchor bolts from each other and from the edge of the surface on which they are installed: Failure to pay attention to this parameter when installing anchor bolts may cause cracks between them or at the edge of concrete or materials.
6- Planting depth: When the load on the anchor bolt is calculated, the required diameter of the anchor bolt is obtained. However, due to improper location or other priorities or limitations of the machines to be deployed, the calculated diameter may not be possible, in which case by increasing the length and depth of anchor bolt planting, this shortcoming can be compensated. .
7- Reinforcing concrete rebars: The presence of these rebars in the anchor bolt installation area provides a stronger foundation for the anchor bolt. Of course, their accidental collision must be prevented.
