Modular Formwork for High-Rise Buildings

2. Horizontal System: Efficient “Quick Form Removal” for Floor Slabs/Beams

2.1 Drophead Slab System

• Steel-frame plywood panel: high-strength steel frame + phenolic-faced plywood, ribbed design on all sides to boost deformation resistance by 30%.

• Standard modules: 12 sizes (0.36–2.16㎡), like TF1812 (1800×1200mm) and TF0606 (600×600mm), ideal for irregular floor slab splicing.

• Support Structure: Steel props with early-dismantle heads (SP series): Q355 inner tube + Q235 outer tube, height adjustable (2000–3500mm), with DH01 early-dismantle device for floors under 5 meters.

2.2 Table Formwork

• Ideal for floor pouring in high-rises, multi-story factories, and underground structures. After pouring, components reuse easily—lifted to higher floors without disassembly. Simpler in structure, easier to dismantle, and more reusable than traditional formwork.

2.3 Flex-Table Formwork

• Designed for slab concrete pouring in complex, narrow spaces. Supported by steel props/tripods with varied support heads, using H20 timber beams as primary/secondary beams, covered with panels. Works for clear heights up to 5.90m.

2.4 ALU-Drophead Slab Formwork

• Material: aluminum alloy frame (18kg/m²) + aviation-grade aluminum plywood.

• Highlights: Integrated early-dismantle head and aluminum frame, 40% lighter than steel formwork—perfect for super high-rise core-tube floors.

• Certifications: Meets EU EN1237 standard, fire rating B-s1,d0 (critical for tunnel/high-rise fire safety).  

3. Vertical System: Versatile Combinations for Wall Columns

3.1 65 Steel-Frame Wall Column Formwork

• Specs: 65mm high steel frame + plywood, customizable size.

• Use: Standard-story shear walls (20–50 floors), concrete surface flatness ≤2mm (no plastering needed).

• Accessories: Quick-dismantle pins (10 seconds/piece), 3x faster than traditional bolts.

3.2Plastic Formwork (Round/Square Columns)

• Material: Modified PP, single-section height 1.2–3m, spliceable into Φ300–Φ1200 round columns.

• Advantages: Lightweight (8kg/m²), no release agent needed, mirror-level finish post-removal.

• Lifespan: 50 uses, 20% cheaper than wood formwork.

3.3 Timber Beam System—Wall Column Formwork

• Structure: C24 timber beams + 18mm WBP plywood, with adjustable braces for complex wall columns (e.g., inclined walls, variable-section columns).

• Case: 45° inclined wall of Yangzhou’s 30-story Science and Innovation Center—adjusted via timber beams, error within ±5mm.

3.4 All-Steel Column Formwork (Round/Square Columns)

• Tech: Block-type steel form + bolt locking, min. round column radius 300mm, max. square column 2m×2m.

• Scene: Giant columns in super high-rise transfer floors (e.g., 1.8m×1.8m column at Wuhan’s 45-story Hang Lung Plaza), bearing 150kN/m².

• Efficiency: Single column installed in <2 hours—50% faster than wood formwork.

4. Super High-Rise System: The “Intelligent Climber” for Core Tubes

4.1 Hydraulic Self-Climbing Formwork (HCB Series) Core Features:

• Efficient & Safe: Fast climbing (5 days/floor avg.), stable operation, less tower crane reliance; robust safety barriers.

• Economical & Convenient: No repeated disassembly—removed post-construction, saving space and reducing loss; minor errors, easily fixed floor by floor.

• Intelligent Control: Electrically controlled hydraulic lifting system for high automation.

• Types & Specs: - Types: HCB-100 & HCB-120, in diagonal brace type or truss type (composite/separate truss).

• Specs: Load: Top platform ≤0.75kN/㎡, others ≤1kN/㎡.Hydraulics: Cylinder stroke 300mm, pump flow *n×2L/min (n = pumps), speed ~300mm/min.

• Capacity: Rated thrust 1000kN & 1200kN.

• Sync: Double-cylinder error ≤20mm.  

5. Lianggong Quality and Service: From Product to Full Life-Cycle Support

5.1 Quality: Military-Grade Standards

• Materials: Standard steel (10% higher yield strength) + US APA-certified (E-1 waterproof) plywood.

• Testing: Third-party checks (e.g., SGS) ensure 12+ indicators (side pressure, deflection) exceed industry standards by 15%.

• Case: Indonesia’s Jakarta-Bandung High-Speed Railway 20-story buildings—withstood tropical rain, zero deformation/leakage.

5.2 Service: Full Life-Cycle Coverage

• Pre-sales: Free BIM design (3 solutions), e.g., Yancheng’s 38-floor landmark—previewed 200+ node collisions.

• In-sales: 24/7 on-site engineers.  

• After-sales: Dedicated staff solve on-site issues promptly.  

6. Conclusion: High-Rise Formwork—Modular, Intelligent, Labor-Efficient

• Lianggong’s 4 systems and 12 products cover all high-rise construction stages. Whether the hydraulic self-climbing “sky builder” for core tubes or the early-dismantle table formwork for standard floors, it redefines construction with industrial logic.

• In 2024, Lianggong’s projects cut time by 22% and labor costs by 35%, driving China’s construction toward “higher, faster, smarter” goals.
