Composition and Characteristics of Climbing Formwork

Components of Climbing Formwork

The climbing formwork comprises lower frame, upper frame, wall-attached hangers, guide rails, hydraulic cylinder system, templates, railings, etc.

Principle of Climbing Formwork

The principle of climbing formwork is to arrange machine positions according to the wall situation. Each machine position is equipped with a hydraulic jacking system. The frame is fixed and connected to the climbing cone embedded in the wall through wall-attached hangers. During climbing, the guide rail is lifted first, and then the frame along with the template climbs along the guide rail.

Characteristics of Climbing Formwork

• The hydraulic climbing formwork can climb as a whole or single frame, with good climbing stability.

  
  

• Convenient operation, high safety, and can save a lot of labor time and materials.

  
  

• Once assembled, the climbing formwork stays in place until the top, saving construction space and reducing template damage, especially the panel.

  
  

• The hydraulic climbing process is smooth, synchronized, and safe.

  
  

• Provides a full-range operation platform, eliminating the need for construction units to set up new operation platforms, saving materials and labor.

  
  

• Minimal structural construction error, easy to correct, with construction error reducible at each layer.

  
  

• Fast climbing speed improves overall construction progress.

  
  

• The template climbs by itself and is cleaned in place, significantly reducing the number of tower crane lifts.

  
  

Overall, the climbing formwork system features easy and flexible operation, safe and stable climbing, high speed, precise template positioning, and does not require additional lifting equipment during construction.

Quality Control of Climbing Formwork

• Before climbing, ensure the concrete wall reaches the required climbing strength, the load-bearing bolts are tightened, and the wall-attached hangers are secure. Check if any components of the frame are disconnected, and confirm the electrical control and hydraulic systems are functioning properly. Ensure the climbing unit sequence is defined.

  
  

• During climbing, ensure the guide rail lifts above the lowest wall-attached hanger. Remove the wall-attached hangers and climbing cones in time. After the guide rail is in place, check if it is seamlessly locked with the wall-attached hangers. Ensure to remove the load-bearing pin after the frame climbs a distance, insert the load-bearing pin once the climb is complete, and insert the safety pin promptly.

  
  

• After climbing, adjust all yokes to the guide rail gear position, turn off all switches, and lock the hydraulic device. Confirm that each machine position’s wall support is in place, and check the connection of individual frame components, climbing units, and railing steel pipes for stability.

  
  

• During the climbing of the template, deviations and twists are prone to occur. To ensure quality, measure relevant parts daily with instruments during normal construction. Correct any detected deviations or twists timely.
