How should formwork assembly be done?


The assembly of formwork varies depending on the type of formwork used. Here are some general guidelines for the assembly of conventional formwork, which is one of the most common methods:

  1. Planning and preparation: Before starting assembly, review the formwork design to understand the dimensions, necessary supports, and materials to be used. Organize all necessary materials, tools, and equipment.

  2. Site preparation: Clean and level the area where the formwork will be erected. Remove any debris, obstacles, or dirt that could compromise the stability or quality of the formwork.

  3. Installation of support beams: Place the support beams around the area where the slab or structure will be built. The support beams should be positioned according to the design, ensuring proper load distribution. Check for leveling and secure them firmly in place.

  4. Installation of props and diagonals: Position the vertical props between the support beams, firmly securing them at the top and bottom. Add diagonals between the props to increase the rigidity of the formwork system and prevent unwanted lateral movement.

  5. Formwork Installation: Place the formwork, which can be made of wooden planks or other materials, between the support beams and braces. Position the formwork according to the design, ensuring proper alignment and leveling. Secure the formwork to the support beams and braces using nails, screws, or staples.

  6. Verification and adjustments: Double-check the leveling of the forms, the stability of the formwork, and the rigidity of the system. Make any necessary adjustments to ensure the accuracy and safety of the formwork.

  7. Reinforcement and bracing: Add reinforcements, such as metal tie rods or steel cables, when necessary, to increase the stability of the formwork. Properly brace the props and diagonals to prevent unwanted movement during concreting.

  8. Inspection and approval: Before proceeding with the concrete pouring, request inspection and approval of the formwork by a civil engineer or responsible supervisor. Ensure that all steps have been carried out correctly and that the formwork complies with safety standards.

It is important to follow the project guidelines and the recommendations of qualified professionals during the assembly of the formwork. Each type of formwork may have specific requirements, therefore it is essential to adapt the above instructions as needed.
