Concrete Staircase and its Formwork

The formwork for the concrete stairs helps to embrace the concrete and ensure that the concrete does not stick into the surface of the formwork. The formwork for the concrete stairs can be achieved through applying the specialised coatings. This helps to maintain the desired finish of the concrete stairs as well as helps to offer liberation from the surface issues. In the formwork building process, concrete has become a well-behaved participant in the process, which helps to preserve the design integration of the concrete stair.

The use of the telescopic tubes helps to make the construction process of the formwork for the concrete stairs. After placing the tubes, a reinforced bubble mat is used to cover and reinforcement and risers have been placed before concreting.

Effectiveness of the formwork for concrete stairs

The formwork plays an important role in determining the structural integrity of the concrete stairs. The concrete of the stairs may not take the desired shape without having proper formwork, which leads to unsafe and unstable stairs in the building structure. In addition, a well-constructed formwork helps to ensure that the concrete in the stairs has cured correctly, which helps to reduce the risk of warping, cracks, or other types of structural issues.

The formwork for the concrete stairs should be strong enough to hold the entire weight of the concrete in the stairs. The formwork should also be flexible enough to be removed after curing the concrete. The long-term durability of the stairs has been ensured by investing in the high-quality formwork. The high-quality formwork also helps to ensure the smooth finish of the stairs.

Different types of formwork for the concrete stairs

Different types of formwork have been used in the construction of the concrete stairs. The selection of the right types of formwork depends upon the budget, design of the stairs, and the specific needs of the design.

Timber Formwork

The timber formwork consists of wooden panels and boards, which have been assembled to form the mold for the concrete stairs. The timber formwork is cost-effective, as well as can be customized, which helps to meet the design requirement of the stairs.

Plastic Formwork

These types of formwork for the concrete stairs are lightweight, as well as the installation and removal process of these types of formwork is also very easy. These types of formwork help to provide a smooth finish for the concrete stairs. The plastic formwork is also cost-effective for repetitive uses in multiple construction projects. Same level of strength and durability has been offered by the plastic formwork as steel formwork or timber formwork. These types of formworks can be used in those construction projects which require heavier loads.

Steel Formwork

The steel formwork for the concrete stairs is durable and reusable as compared to the timber formwork. These types of formwork for the concrete stairs are suitable for those projects which require more precision in the dimensions of the stairs. These types of formwork are also less prone to warping and sustainable for a long period of time. Though the steel formwork is more expensive as compared to the timber formwork, as a result, it is not suitable for the smaller projects with limited budgets.

Precast Formwork

In the precast formwork for the concrete stairs, the prefabricated molds have been used, which are built in the controlled environment before being transported into the construction site. In the case of requiring uniformity in the stair designs, or there are some on-site constraints including weather or space, these types of formwork can be used. In this case, it is necessary to ensure that the precast formwork should be fitted accurately into the site’s design.

The building process of the formwork for the concrete stairs

The construction of the concrete formwork stairs can be done in several processes. During the construction procedure, the formwork for the concrete stairs should be robust and strong enough for supporting the weight of the concrete in the stairs until the concrete dries. The steps involving the construction of the concrete stairs include:

Building the rise

The construction of the formwork for the concrete stairs has started by constructing the rise or the vertical part of the steps. In this context, the measurement of the height of each step needs to be taken and the sidewalls have been cut into the appropriate sizes. The two sidewalls of the stairs need to be aligned on both sides of the concrete stairs. It is also necessary to ensure that the rises are level and plumb and have been supported by stakes or braces.

Creation of the landing

The next step is the creation of the landing or the flat surface among the steps of the stairs. The length of timbers has been used to mark out the landing’s size and shape, after that, the sidewalls have been cut and aligned to be fitted. The sidewalls have been attached securely to the risers, which helps to ensure that the sidewalls are level.

The installation of the treads

After the construction of the rise and landing, the treads have been installed. The treads are the horizontal part of the stairs, between each step of the stairs. Appropriate measurement has been done to cut the treads into size, which helps to ensure that the treads are level and attached to the sidewalls securely. This procedure has repeated until all the steps are completed.

Final preparation for the formwork

Strong and reliable material should be taken to construct the entire formwork for the concrete stair. Builder securely attached riser and treads, and the stability in the meantime of pouring of the concrete is paramount. After that, builders have installed bracing and applied oil or wax for easy removal of the formwork after setting the concrete.
