In the world of construction; There are various types of materials that facilitate certain processes on site. But they are usually single-use and that does not support economic savings. The theme that will announce today is: PROPS. For this we are going to define it. (We offer best results for Props and struts formwork for Construction Companies in UAE.)
What Is a Strut?
We place the props are temporary columns that with the aim of supporting the weight of the upper structure of a work. Before the concrete or concrete of the definitive columns and beams sets. These are elements of vital importance within a construction work. Especially if it is under construction with two or more floors.
Types Of Props
Currently there are different types of props. Which help with the construction objective. Each one has different characteristics. We make it from the type of material. Their size and quantity depend on supported load within the work.
Finally, its acquisition is the choice of the person in charge of the work. And the budget that is available. So, the most used types of props in construction are the following:
1. Metal Struts
They are more resistant and, not deformed since they worn-out quickly. They have greater durability. It helps speed up the formwork and stripping times.
Its height ranges from 1.80 to 4.50 meters. The load capacity of this type of props is from 1 to 2.2 tons. For its use, we recommend it to adjust the height through the regulation nut that it has. Ensuring the pin in the holes of the prop.
For Construction you can purchase metal props that range from 3 m to 4 m, Hot-dip galvanized. Which is why it has a weight advantage over conventional 26 Kg props.
2. Steel Props
This steel strut option is the strongest out there. Due to the fact that steel is a metal with greater resistance. We recommend it to use these props for jobs or works where there are areas of humidity. The main reason is that the props will be less likely to rust and corrode.
Its load capacity is from 500 to 3000 kg. The working height of these comprises between 2 and 6 meters. This type of prop is compatible with recoverable formwork systems. Both for building and civil works. Facilitating the realization of all types of solid slabs or lightened slabs. Both unidirectional and bidirectional.
3. Aluminum Props
These types of props are lighter and more practical than steel ones. They can consider an excellent option. If require continuous transport. We recommend Its use in works where the environment of the work does not present a risk of rust or corrosion.
One disadvantage is that they have a shorter useful life. Since aluminum is more ‘delicate’ when treated on site. They have a greater load capacity and allow working at greater heights.
Although can used these as an independent prop. Generally assembled them, “tied” together. Forming load-bearing towers with bracing frames. It is also common to join them in height. We use them with formwork systems for singular buildings. And/or for civil works. When there is a load range and height greater than that of steel props.
4. Wooden Props
It is the most well-known and crowded option when it comes to using it on construction sites. Either because they do not know any other prop material. In addition, that wood is more accessible in price and use it for a long time.
These props have a length of 2.40 m. One of the disadvantages of this type of props is that they can only use once. This causes a lot of material waste.
To reach higher heights, two side bars must nail to another section of purlin. This in order to make a good support, this implies time. It recommends for this type of props to make a regular, level base, to prevent them from giving way when pouring the concrete and for the props to have excellent contact with the ground.
5. Telescopic Props
We make these exclusively of metal and use these in the construction of metal scaffolding. They can change height easily and quickly. These struts can help support the weight of structures. Especially columns; when built it, placed them from the bottom up. To fulfill their function correctly. They require a support point. The contact area to transmit loads and reinforcements.
You Can Purchase Inclined Telescopic Props:
They are perfect for supporting formwork and reach a height of 5.50 meters. The closed load capacity is 1,410 kg and the open face capacity is 360 kg.
Benefits Of the Struts:
- Metal props are lighter for transport and loading, as well as being resistant to support the weight required for construction, unlike wooden props.
- Wooden props at the time of purchase are cheaper. Unlike goal struts but over time these are an investment that pays for itself over time as they are reusable.
- Savings and better use in the setting time, with the exception of wooden props, which take a little longer.
- If they use it correctly and have a correct use, their life time is longer than conventional wooden props.
- The props allow to graduate to a certain height and use them in different works independently, while the wooden props take a little more time to do this maneuver.
There are a variety of props to adapt them to the needs of the work, in addition to having extensive options.
Factors For Choosing the Correct Prop
It seems an easy task at first glance. But emphasize as in this blog. It will depend on the construction manager. Who must consider these factors to choose the indicated prop.
Acting Load:
The acting load per m2 that the props must support and calculate. Adding the weight of the slab itself. The execution overload (weight of the operators, formwork, as the case may be).
Upright load capacity:
Each upright has a minimum load capacity for each free height. The manufacturer determines it. It is based on a table based on its class (local regulations or European regulations). The load of the prop depends on the following:
- Diameter of the cylindrical body,
- The thickness of the tube,
- The geometry of the prop itself
- And its ability not to buckle.
Free height of the prop:
It is important to know the free height in which the prop will work on site. This data is very important to be able to obtain the load capacity according to the manufacturer’s data (point 2). Of course, the more clearance there is, the more will reduce the load capacity of the strut.
Number of props:
Once the data in the points described above have been determined, must calculate the minimum number of props to place it under the slab, depending on the acting load and the load capacity at the free height of worked.
Price:
Of course, whenever you seek to optimize the prop based on the preceding points, it will allow you to find the correct prop, with the minimum necessary load capacity and the cheapest price.
