Table formwork (also known as flying formwork) is a large-scale tool-type formwork system in which the formwork panel, primary and secondary beams, and the lower support system are pre-assembled into a standard table-shaped configuration. During construction, the table formwork can be lowered for demolding, pushed out horizontally, and then lifted as a whole unit by a tower crane using a dedicated lifting device (such as a C-hook) to "fly" out of the floor and be transferred to the next level, enabling rapid overall turnover of the floor slab formwork.
Product Structure and Components
-
Formwork Panel and Beam System: Utilizes high-quality plywood or aluminum formwork panels, with aluminum beams, steel beams, or timber I-beams laid underneath as primary and secondary wales.
-
Support System: Composed of adjustable steel props or high-capacity scaffold frames, providing stable vertical load-bearing capacity.
-
Translation and Demolding Mechanism: Equipped with demolding lifting screws, wheeled traveling trolleys, and horizontal push-out rails, facilitating demolding and outward translation.
-
Flying Formwork Lifting Mechanism: Works in conjunction with a dedicated C-hook or slings to ensure balance and safety during integral lifting by the tower crane.
Key Product Advantages
| Advantage Dimension | Detailed Description |
| Integral Turnover · Ultra-Fast Construction | No need for piece-by-piece dismantling and reassembly; the entire unit is lifted and transferred to the next construction level, shortening the construction cycle of each floor by 2-3 days. |
| Smooth Surface · Minimal Joints | The large-area integrally assembled panel greatly reduces formwork joints, delivering excellent concrete casting quality that can achieve an architectural concrete (fair-faced concrete) finish. |
| Significant Labor Savings · Low Loss Rate | Reduces labor for handling and assembling/disassembling scattered components at height by over 70%; components do not scatter or get lost, resulting in extremely low turnover loss. |
| Safer Work at Height | Frame assembly and finalization are completed on the ground or on safe working platforms, reducing safety hazards associated with piecemeal assembly at height. |
Typical Application Scenarios
-
Large-Bay and Column-Grid Structures: Floor slab pouring for high-rise/super high-rise office buildings, mixed-use complexes, hotels, and premium residential buildings.
-
High-Rise Buildings with Many Typical Floors: Concrete works with uniform floor heights, high structural repetition rates, and extremely demanding requirements for construction schedule and floor slab flatness.
