全国型枠工業会 List of Products and Services

The "Residual Formwork Method" is a construction technique where the formwork used for pouring concrete is left in place as part of the structure after the concrete has been poured, without being removed. It utilizes thin precast cement concrete formwork products that incorporate reinforcement materials and assembly components. This eliminates the need for demolding and transportation work, allowing for a reduction in construction time. Additionally, since scaffolding is not required, it contributes to improved safety. Furthermore, it helps reduce construction waste, leading to a decrease in environmental impact and supporting efforts towards the SDGs. 【Features】 ■ Significant reduction in total costs for concrete work due to shortened construction time, improved safety, and reduced construction waste. ■ The steel reinforcement embedded in the formwork uses a "double coat cationic electrodeposition coating (epoxy resin electrodeposition coating)" that excels in rust prevention. ■ Effective in various sites such as roads, tunnels, bridges, and dams. ■ Over 12,000 construction achievements annually. ★ A photo collection of construction examples is currently available. Please view it from "PDF Download." Feel free to contact us with any inquiries.

The "Pier Stone Method" is a groundbreaking landscaping technique that revives the traditional craftsmanship of stone masons through the combination of residual formwork (pier) and residual decorative materials. Residual decorative materials refer to the landscaping materials such as natural stones, gravel, and thinned wood that are installed using the through-holes of the residual formwork (pier) in this method. Since the residual decorative materials are integrated with the cast-in-place concrete through anchors via the pier's through-holes, there is no concern about peeling or falling off. 【Features】 ■ The design pattern of the residual decorative materials is devised to avoid continuous joints, resulting in a natural joint finish. ■ While maintaining the stable strength of cast-in-place concrete structures, the aesthetic beauty of traditional dry stone walls and similar features can be reproduced. *For more details, please refer to the PDF materials or feel free to contact us.

The "W Mer Method" is a soil cement construction method that effectively utilizes locally generated soil and sediment, employing a residual formwork system for the construction of external protective concrete (cover concrete). By vertically installing the internal formwork, it is possible to ensure proper compaction of the internal material (INSEM material) even at the ends near the formwork panels. It can also be applied to the ISM method. 【Construction Examples】 ■ Shizuoka Prefecture Fuji Civil Engineering Office, First-Class River Improvement Work on Denpozawa River ■ Chubu Regional Development Bureau Tajimi Sediment Control National Route Office, Kiso River System Naka Tsutsumi No. 2 Sediment Control Dam Construction ■ Kinki Regional Development Bureau Kinokawa Dam Integrated Management Office, Sako District Landslide Countermeasure Work ■ Kyushu Regional Development Bureau Tachino Dam Construction Office, Tachino Dam Entrance Closure Embankment and Other Works *For more details, please refer to the PDF materials or feel free to contact us.
