We propose solutions for labor-saving, short delivery times, and technical challenges in body construction.
Proposal-based solutions that shape ideas through consistent production. Leave the circular formwork, system formwork, and support work planning to us.
Our job is to give "shape" to concrete that would otherwise flow away as it is. We can consistently plan, design, and produce everything from circular (arch) formwork, irregular formwork, and special formwork to support materials, large formwork, and system formwork necessary for civil engineering and construction projects. We will propose solutions to shorten construction periods, reduce costs, and address the shortage of skilled workers. [Examples of Projects] ■ System Formwork ■ No-Separation Method ■ Arch Truss Support ■ Custom Machined Formwork *For more details, please download the PDF or feel free to contact us.

basic information
○ System Formwork A construction method where formwork is assembled in large sections and installed using a crane. It is effective for shortening construction periods and addressing labor shortages. We handle everything from formwork materials to support components in-house. We can provide assembly guidance at construction sites anywhere in Japan. ○ No-Separators Method This method does not use separators (formwork support materials) during formwork erection, relying solely on the strength of the steel to withstand concrete pressure. Since there are no separators, there is no risk of water leakage, and the finish is also beautiful. ○ Arch Truss Support By bending steel into an arch shape, we can easily stabilize complex formwork structures. We will discuss and plan the support framework design with you. ○ Real Wood Grain Processed Formwork This allows for the pouring of concrete with a beautiful wood grain finish. We will plan the project incorporating our past achievements and experiences.

Detailed information
-
Large boat-shaped formwork completion. This is the launch of the large assembly formwork system. It has been praised on site for contributing to the shortening of construction periods and significant cost savings in labor.
-
Lifting of large assembly frames After the large assembly, only lifting is done with a crane, which leads to reduced work speed and personnel costs.
-
Tunnel entrance This is the formwork for the entrance of the Bara group. We supply bamboo-split circular formwork and support materials. We also provide assembly guidance!
-
Government building roof construction (architecture) This is a project that requires 3D processing. It was a massive building that took about a year to complete all processes. The entire company worked together to carefully discuss, incorporate into 3D CAD, and further process the project.
-
This is a solid cedar board formwork. By attaching cedar boards to the panels, the finish achieves a beautiful wood grain appearance. In this project, the solid formwork is being processed into a circular shape.
-
This is the completion of the actual formwork. It is a site where the actual cedar board formwork has been processed into a circular shape. With the cooperation of the general contractor and the formwork carpenters, it has resulted in a beautiful finish.

Koyo Shokai Co., Ltd. is a comprehensive manufacturer of concrete formwork used in various construction projects. We possess the craftsmanship to produce complex structures, including circular formwork, arched formwork, and special formwork. Additionally, we have our own metalworking department, allowing us to provide one-stop planning, design, and manufacturing services for various support materials, truss materials, and system formwork, from formwork to support structures. We manufacture and sell formwork for construction panels, bridge piers, wagons, box culverts, shafts, tunnels, and various trusses. In recent years, to meet the diverse needs of the field, we developed a transparent resin concrete formwork called "Mieru Form" (NETIS registration number KK-080044-VE), and in December 2019, we re-registered it as a new technology under the name "Clear Form" (NETIS registration number KK-190028-VE), which allows for free design and offers proposals for creating safe and secure structures. Koyo Shokai provides comprehensive formwork and support planning tailored to the needs of the site, not just simple formwork design.
