五十嵐建設工業 List of Products and Services

The "Just Preet Method" is a formwork technique that improves the dual insulation method by using insulation materials (expanded polystyrene) as formwork instead of wooden molds when shaping reinforced concrete walls and columns, enhancing workability and the quality performance of the structure. By using panels made of insulation materials, the formwork functions as insulation, eliminating the need for separate formwork removal and insulation work. Additionally, by utilizing proprietary analysis software integrated into a rebar detection device, it is possible to check the filling condition of the concrete without removing the formwork. 【Features】 ■ Shortened construction period ■ Improved insulation properties ■ Enhanced durability ■ Improved workability ■ Assurance of quality *For more details, please refer to the PDF materials or feel free to contact us.

• Housing structure technology/long-term superior housing technology
• Heat insulation and heat shielding methods

The "Open Shield Method" is a patented construction method for burying culverts and open channels underground. It is a construction method that serves as an alternative to traditional excavation and shield methods. There are four types based on the construction method. It primarily focuses on urban areas, close proximity construction, soft and hard ground, and high groundwater areas, ensuring not only safety but also economic and environmental considerations. 【Features】 ■ Capable of constructing sharp curves ■ Can be constructed close to buildings and other structures ■ Usable in soft ground and aquifers ■ The upper part of the shield can be opened ■ Low noise and vibration *For more details, please refer to the PDF materials or feel free to contact us.

Igarashi Construction Industry has been engaged in the development of new products through civil engineering and construction projects not only in Niigata Prefecture but also in the Kanto region since its founding in the 4th year of the Taisho era. We are challenging new values in all construction scenes, including our entry into environmentally friendly civil engineering that takes natural landscapes into consideration and our proactive challenges to achieve high-quality, low-cost construction through new methods. In response to the aging society, we established a group company, Higashi-Nihon Welfare Management Services, in 2002, and have actively expanded our operations primarily focused on paid nursing homes. In recent years, we have also expanded our business scope to include services for nursing care products and meal provision. With the accumulation of these know-how, we have been able to assist with many projects in the medical and welfare fields. 【Business Activities】 ■ Construction Business ■ System Construction Business ■ Civil Engineering Business ■ Consulting Business *For more details, please refer to the PDF materials or feel free to contact us.

The "Just Preet Method" differs from traditional wooden formwork by using insulation materials directly as formwork, which reduces the hassle of removing the formwork, minimizes damage, and decreases waste disposal, allowing for shortened construction periods and cost savings! It achieves high airtightness and high insulation performance with an internal and external insulation structure of 110mm (55mm internal + 55mm external) that meets next-generation energy-saving standards. 【Features】 ■ No need for formwork dismantling or insulation installation ■ External insulation method possible with the same panel ■ Improved durability ■ Prevention of condensation ■ Enhanced insulation properties *For more details, please refer to the catalog or feel free to contact us.
