If you're working on a large-scale construction project, you might be wondering how many formwork props you'll need to support your load. The standard load that one formwork prop can take depends on its size. However, most props max out around 3,300 to 3,500 kg. Below are some of the factors to consider when deciding on how many formwork props you'll need:
1. Rating of the Prop
Remember that the amount of weight that a formwork prop can support will depend on its length. For instance, it is a size 0 prop; this is the shortest prop because it extends to only about 1.1 to 1.8 metres which can support up to 3,000 kg. On the other hand, if it is a size 4 prop, extending to 4.9 metres, it can only support around 1,300 kg. You can see the difference between the two. So, as a rule, make sure to use shorter formwork props for larger jobs.
2. Prop Placement Angle
Did you know that formwork props can only reach their maximum structural load-bearing capacity if they are completely straight? That's right. A deviation of even 1 to 2 degrees will severely impact the prop's ability to support the load. That's why you need to make sure that your props can be supported vertically at the best angle.
3. Supporting Scaffolding Usage
One of the ways you can strengthen your formwork props is by using standard scaffolding materials. Horizontal bracing can help ensure that in case one prop fails, the other ones will remain upright. Doing this is highly recommended for those who are creating structural supports that use two or more formwork props.
