The guidelines for handling and installing steel rebars in construction sites typically include the following:
1. Storage: Steel rebars should be stored on a flat and dry surface, preferably on elevated racks to prevent contact with the ground and avoid rusting or damage.
2. Transportation: Rebars should be moved using appropriate lifting equipment, such as cranes or forklifts, to prevent excessive bending or mishandling.
3. Inspection: Rebars should be inspected for any defects, such as bends, cracks, or excessive rust, before installation. Damaged rebars should not be used.
4. Cutting and bending: Rebars should be cut and bent using appropriate tools and equipment, following the specifications and dimensions provided in the construction plans.
5. Placement: Rebars should be placed accurately and securely within the concrete structures, ensuring proper alignment and spacing as per the design requirements.
6. Tying: Rebars should be securely tied together using wire or approved tying methods at the intersections to maintain the desired positions during concrete pouring.
7. Embedment: Rebars should be properly embedded within the concrete to ensure sufficient coverage, typically complying with the minimum concrete cover specified in the design.
8. Safety: Adequate personal protective equipment (PPE), such as gloves and safety boots, should be worn by workers during rebars handling and installation to prevent injuries.
It is important to note that specific construction projects and local regulations may have additional guidelines or requirements for handling and installing steel rebars. Therefore, it is crucial to refer to the project specifications and consult with relevant experts or authorities for comprehensive guidelines.
