FWK Lianggong hydraulic protection screen for construction is a modular protection system suitable for various building scenarios, mainly used for safety protection and operation support in the construction of floor slabs, facades, etc. The entire system is always guided by the building structure, maintaining stability even during repositioning.It can be shifted by crane or hydraulic means, adapting to different needs, and can also be combined with a protection screen and loading platform or protection screen and unloading platform to enhance site efficiency.
The system integrates the functions of a protection screen and a working platform, providing operating space for construction of slab stop-ends, prestressed floor slabs, etc. It can be flexibly adjusted according to the building's geometric shape, applicable to complex building forms (such as inclined facades, structures with varying inclinations, etc.). Its core components include vertical profiles, guiding shoes, floor supports, hydraulic devices, etc., enabling quick assembly and disassembly through standardized connections.
| Category | Specific Parameters |
| Applicable Storey Height | 2.70-4.50m |
| Load Capacity | Vertical load: Maximum 30kN for rigid floor supports, maximum 60kN for adjustable floor supports Horizontal load: Maximum 60kN Allowable load on working platform: 1.5kN/m² (150kg/m²) |
| Dimensional Parameters | System clearance: The clearance between the floor slab and vertical profile is adjustable (85-345mm; fixed for rigid supports, continuously adjustable for adjustable supports) Minimum slab thickness: 19-48cm depending on the type of stop anchor |
| Material and Strength Requirements | Concrete cube compressive strength: At least 10N/mm² Most components are galvanized or painted steel to ensure corrosion resistance |
| Inclination Adaptability | Facade inclination: Vertical profiles can incline ±10° forward/backward or sideways Varying inclinations: Only adjustable floor supports can be adjusted under load |
| Hydraulic System | Hydraulic cylinder lifting step: 300mm, capable of repositioning independently of a crane |
| Weight of Core Components | Vertical profile (10.75m): 305kg Rigid guiding shoe: 19.0kg Rigid floor support (90cm): 25.0kg |
High Safety: The system is always connected to and guided by the structure during lifting and repositioning, allowing safe operation in harsh weather such as strong winds. Operators are less affected by climate, and all connection points are regularly inspected to ensure stability.
High Flexibility: The influence width can be adjusted to fit the structure's geometry, and the working platform can be installed anywhere on the scaffold. It is suitable for storey heights of 2.70-4.50m and supports variable clearances between the floor slab and vertical profiles (85-345mm).
Versatility: It can be integrated with a loading platform (suitable for constant or non-constant storey heights), supporting inclined facades (±10° inclination) and structures with varying inclinations. Hydraulic repositioning allows independent operation without relying on a crane, improving construction efficiency.
Modular Design: Components are standardized, with simple assembly, disassembly, and repositioning processes, enabling quick adaptation to different construction stages.
