Lego-Style Interlocking Block Steel Formwork

Scope of Application

1. River & Water Conservancy Projects

   Ecological river slope protection, dike reinforcement, tidal flat soil and water conservation, fish nest revetments and flood retaining walls. Interlocking blocks reserve spaces for grass planting, balancing flood control and ecological greening.

2. Municipal Landscape Projects

   Waterfront retaining walls for urban pocket parks, landscape planting troughs, scenic area isolation walls, temporary municipal fences and sidewalk slope support.

3. Rural Infrastructure Projects

   Modular wall blocks for new rural self-built houses, farmland dike protection, drainage channel retaining walls and courtyard landscape enclosures.

4. Road Infrastructure Projects

   Highway subgrade slope protection, anti-collision retaining blocks on slopes, retaining walls at tunnel entrances and exits, side support for comprehensive pipe galleries.

5. Overseas Export Projects

   Water conservancy and precast wall block projects in Mongolia, Southeast Asia, Central Asia and other overseas regions. Standard specifications comply with international construction standards, and bulk customized export orders are available.

Structural & Technical Advantages

1. Product Structure

1. Main Steel Panels: Thick cold-rolled steel plates are adopted. Side and bottom plates are integrally bent with built-in demoulding draft angles. The inner walls are polished smooth to prevent concrete adhesion.
2. Reinforcing Rib Structure: Standard square tube ribs are fully welded to disperse lateral concrete pressure, resisting deformation and bulging after long-term repeated use.
3. Interlocking Forming Cavity: The mould cavity comes with integrated concave-convex male-female joints. The produced cement blocks have built-in interlocking structures that fit tightly without gaps during masonry, eliminating mortar filling requirements.
4. Quick-Disassembly Locking Components: Top positioning calipers for limiting, plus side quick bolt fasteners for secure locking. The split half-opening design allows single-person demoulding operations.
5. Reserved Embedding Holes: Built-in PVC sleeve preformed holes for manufacturing hollow blocks, which reduce self-weight and improve drainage & air permeability.

2. Core Technical Strengths

1. Precision CNC Machining: Dimensional tolerance controlled within ±0.5 mm. Moulds from the same batch are fully interchangeable, and blocks produced by different moulds can be freely assembled and matched.
2. Full Welding & Anti-Corrosion Process: Internal and external welding seams are fully polished flat. Anti-rust primer is sprayed before delivery to resist rust during outdoor storage on construction sites and extend service life.
3. Lightweight Split Design: Each mould is split into two separate pieces, requiring no large hoisting equipment. Manual handling and loading/unloading cut transportation costs.
4. Polished Demoulding Design: Highly smooth inner surface treatment enables fast stripping with a small amount of release agent, producing intact blocks without chipped corners or edges.

Comprehensive Application Functions

1. Mass Prefabrication Function: Batch production of interlocking concrete blocks at mixing stations and precast yards, with hundreds of blocks output per day to support mass stock preparation for large-scale projects.
2. On-Site Cast-In-Situ Function: Direct formwork erection and pouring of retaining walls & slope protection on site, eliminating prefabrication and intermediate transportation links to shorten construction cycles.
3. Ecological Greening Function: Hollow blocks can be filled with soil and planted with grass after forming to build ecological slopes, meeting soil and water conservation standards for water conservancy projects.
4. Reusable Turnover Function: Wear and impact resistant all-steel structure supports over 300 pouring cycles per set, delivering lower overall costs compared with plastic moulds.
5. Fast Assembly Function: Finished blocks lock together without cement mortar. Construction speed is boosted by 50% versus ordinary bricks, greatly cutting cement, sand and gravel consumption.
6. Flexible Customization Function: Length, width, height, hollow aperture and interlocking joint sizes can be adjusted per project demands. Custom mould development is available for special-shaped landscape retaining blocks and unique slope protection units.
7. Reusable Temporary Construction Solution: Blocks used for municipal temporary fences and construction separation walls can be disassembled and recycled after project completion, drastically reducing construction waste.

Product Overview & Integrated Advantages

1. Product Overview

2. Integrated Comprehensive Advantages

1. Lower Construction Costs

   High mould turnover reduces single-piece prefabrication costs. Finished blocks require no mortar for laying, cutting labor and raw material input, slashing overall project costs by 25%–30%. Only a two-person team is needed for demoulding and prefabrication work, cutting labor demand by more than 40%.

2. Faster Project Schedules

   Mould assembly and disassembly need no professional welders or heavy machinery for fast prefabrication. On-site block splicing is simple, shortening construction periods by nearly half for equivalent work volumes, ideal for time-sensitive municipal and water conservancy projects.

3. Superior Finished Product Quality

   High rigidity steel formwork resists bulging during pouring, delivering uniformly sized, smooth-surfaced blocks with tight interlocks. Completed walls feature strong overall stability, superior erosion resistance and anti-collapse performance compared with standard concrete bricks.

4. Long Service Life & Easy Maintenance

   Thickened steel plates plus anti-rust coating withstand concrete corrosion, drops and impacts, resisting deformation and damage during long-term outdoor use. Local damaged ribs can be replaced separately instead of scrapping the entire mould set.

5. Eco-Friendly & Cost-Efficient

   Blocks can be disassembled and recycled to minimize construction waste. All-steel moulds have no one-time consumable loss, better complying with green construction and low-carbon infrastructure standards than wooden and plastic formwork.
