There are multiple approaches to pouring concrete with steel frame formwork, depending on the specific project needs.
1. Traditional Pouring: The most commonly utilized method entails assembling the steel frame formwork on-site and pouring concrete directly into it. Afterward, the concrete is left to cure and harden before the formwork is removed.
2. Slip Forming: This technique is frequently employed for tall structures like skyscrapers or chimneys. The steel frame formwork is continuously raised as concrete is poured, enabling a seamless pour without any joints. To achieve a smooth and even finish, specialized equipment and skilled workers are required.
3. Jump Forming: Similar to slip forming, jump forming is employed for tall structures, but it involves pouring concrete in sections or "jumps." After each jump, the steel frame formwork is lifted to the next section, allowing for a continuous pour. This method is commonly used for building cores or elevator shafts.
4. Pre-cast Panels: In this method, pre-cast concrete panels are manufactured off-site and then transported to the construction site. The steel frame formwork is used to secure and seal the panels in place during installation. This approach is often utilized for fast-track construction projects where time is a critical factor.
5. Tunnel Forming: This technique is commonly used for constructing walls and slabs in buildings with repetitive floor plans, such as residential or commercial structures. The steel frame formwork is assembled to create a tunnel-like structure, and concrete is poured inside. This method allows for rapid construction as multiple floors can be poured simultaneously.
Each approach presents its own benefits and considerations, and the selection of the method will depend on factors such as project requirements, timeline, budget, and the expertise of the construction team.

2. Slip Forming: This method is often used for tall structures such as skyscrapers or chimneys. The steel frame formwork is continuously moved upward as the concrete is poured, allowing for a continuous pour without any joints. This method requires specialized equipment and skilled workers to ensure a smooth and even finish.

4. Pre-cast Panels: In this method, pre-cast concrete panels are manufactured off-site and then transported to the construction site. The steel frame formwork is used to hold the panels in place while they are connected and sealed. This method is often used for fast-track construction projects where time is of the essence.
5. Tunnel Forming: This method is commonly used for constructing walls and slabs in buildings with repetitive floor plans, such as residential or commercial structures. The steel frame formwork is assembled to create a tunnel-like structure, and concrete is poured inside. This method allows for a rapid construction process as multiple floors can be poured simultaneously.
Each of these methods has its own advantages and considerations, and the choice of method will depend on factors such as project requirements, timeline, budget, and the expertise of the construction team.
There are several methods of concrete pouring with steel frame formwork, including traditional pouring, slip form pouring, and precast pouring. Traditional pouring involves placing the formwork and reinforcing steel, then pouring the concrete into the formwork and allowing it to cure. Slip form pouring is a continuous process where the formwork moves vertically as the concrete is poured, creating a continuous wall or structure. Precast pouring involves precasting concrete elements off-site and then assembling them using steel frame formwork on-site.
