The selection of the anchor we are going to use for our installations is always a question that generates doubts. We are not sure if the anchor will have the necessary extension, thickness, or even the resistance required for the installation of different materials. In the case of Divetis, it is a recurring question from our customers when they are about to install our bumpers, delimiting bollards, speed reducers, chocks, loading dock protections, etc. Therefore, we will try to explain the difference between each of them and their uses. 1. Factors that influence the anchor selection. 2. Types of anchoring or types of anchor 3. Types of action depending on the type of anchor 4. Selecting the correct anchor size 5. Types of base for the anchor 6. Difference between solid materials and lightweight materials 7. Anchors and bumpers, which one do I choose?
Factors that influence the anchor selection
There are many factors to consider when choosing the anchor or fastener we will use to install different objects. Therefore, in order to have a clearer idea of what we should consider, we will define our hypotheses based on the following: 1. Material/base on which the anchor will be placed First, we must be clear about the type of material or base on which our anchor will be located, the most important thing to consider when choosing the anchor. Depending on the type of material from the most solid to the lightest, we will choose the material of our anchor, its width, and length. 2. Load that each fastening will support We must be clear that the anchor we have chosen is capable of supporting the pressure that will be exerted on it. Not only do we have to think about the load that the anchor will support, but also about the capacity of our base to resist that load. 3. Weight of the object To determine which anchor to use, it is necessary to know the exact weight of the object that will be installed to determine the capacity that this object has to absorb the load before it reaches the anchor. Therefore, we will take into account the following factors: a. The more anchor points our anchor has, the greater the surface this anchor will use for fastening, thus obtaining an optimal fastening. b. In addition, taking into account the depth at which the anchor will be placed, we will see that; the greater the depth of the anchor, the greater its resistance.
Types of anchors
There are different types of anchors that adapt to the different needs of the objects to be installed. If we could classify the different anchors on a scale of resistance, the plastic anchor would be the least resistant and the chemical anchor would provide the greatest fastening, therefore the types of anchors are as follows:
a. Plastic/Nylon anchor
b. Metal anchors
c. Chemical anchors
Types of anchor action
Depending on the object to be installed, the base, and the action of the anchor, we will achieve a lower or more powerful level of fastening. For this, it is important to know the different actions that an anchor can exert on the base material. Anchors can act in the following ways depending on the base material. a. Expansive: The anchor expands in the solid material b. Adaptive: The anchor adapts and increases its volume c. Adhesive: The material incorporates an adhesive that adheres to the base walls. The metal piece is inserted into it, which will also adhere to the inner walls of the anchor in the same way as to the base. Once the adhesive solidifies, it fixes the inner and outer walls to ensure a stable and durable fastening. When the base material is not solid, the use of a sieve is recommended to lighten the mix.
What are the most common base materials?
The most common base materials are solid concrete, solid brick, and stone as the most robust materials, and as lighter materials we can find plasterboard, hollow brick, or hollow concrete.
What size anchor do I use?
It is true that the longer the anchor, the better the fastening it can offer. Since we do not always have the opportunity to use very long anchors, we must consider three factors: a. Base material b. Available distances (depth) c. Estimated load Therefore, we can use the following table with approximate loads and depending on the type of material, whether it is hollow or solid. It is always preferable to use anchors that support slightly more load than we plan to use.
Which anchoring do I choose for my bumpers?
We hope you have a clearer idea of which fastening to choose to install the anchor. It is very important to consider from the beginning what load the bumper will support. Depending on the load to be supported, a different bumper must be chosen as there are various options. It is not the same to have a bumper to withstand the impact of a light vehicle or car as it is to withstand the impact of a truck. If after reading the article you still have doubts about how you should install your bumper and the entire process prior to installation, you can write to us or call us and we will be happy to assist you.
