3. Tying and Fastening
After cutting and bending, the steel bars are tied together using wire or welded in place. This process is essential for maintaining the integrity of the steel framework within the concrete. The technique of tying is as much about strength as it is about ensuring ease of concrete placement.
4. Placement and Positioning
Correct placement and positioning of the steel reinforcement within the concrete forms are vital. The steel must be placed in a way that it remains undisturbed during the concrete pour and is completely encapsulated by the concrete, without touching the formwork.
5. Using Rebar Chairs and Spacers
Rebar chairs and spacers are used to maintain the correct positioning of the rebar within the concrete. These tools ensure that the rebar is held at the proper height and spacing as per the design specifications, which is critical for the structural performance of the concrete.
6. Checking and Adjustments
Continuous checking and adjustments during the steel fixing process are important to ensure accuracy. This step involves verifying alignments, spacings, and the overall setup before the concrete is poured.
7. Adapting to Special Requirements
Different construction projects may have unique requirements based on their design, load-bearing needs, or environmental factors. Steel fixers must adapt their techniques to meet these specific demands, ensuring the reinforcement is suitable for the structure’s intended purpose.
