コンステック Company Profile

Our company is working on the development of support technology utilizing AI to streamline and reduce labor in the inspection of building exteriors, with the aim of improving the working environment. We are targeting practical application in fiscal year 2026 with a system that accommodates the diverse painting finishes unique to buildings. In exterior wall inspections, crack detection typically relies on the eyes of the inspection technician, and on-site tasks such as field notes, dimension measurements, and photography can be resource-intensive. However, the system we are developing detects cracks from images taken with a digital camera, allowing for digital processing of on-site work and drafting, which reduces time. Additionally, it eliminates discrepancies in detection among different inspectors, resulting in consistent inspection results. The core technology of this system is being constructed through the key research project "Development of Support Technology for Inspection and Diagnosis of Reinforced Concrete (RC) Building Exteriors Utilizing AI" conducted by the Hokkaido Research Organization, a local independent administrative agency, from fiscal years 2023 to 2025. A prototype has already been completed and was unveiled for the first time at our exhibition "Techno Fair 2024."

The fire-resistant and non-combustible polymer cement mortar repair material "EPC Fireproof Mortar" has achieved a cumulative construction area of approximately 30,000 m² since its development and sales began in July 2018, following repeated applications in contracted construction projects. (This figure is calculated based on the total amount used divided by the usage per square meter [conversion value based on a repair thickness of 10 mm].) Some polymer cement mortars for concrete repair available in the market did not meet the performance requirements during a fire. In response to this background, our company developed a polymer cement mortar with excellent fire resistance while maintaining adhesion performance and durability. EPC Fireproof Mortar is suitable for repairing insufficient cover thickness and cross-sectional defects in RC structures, and it possesses fire resistance and material performance that comply with building codes. Additionally, this product has obtained non-combustible material certification and conforms to various repair material guidelines, making it usable for both new construction and renovations.

In the seismic retrofitting of steel frame buildings, we have developed the "Adjoint Method," which involves bonding reinforcement members to existing H-shaped steel and existing square steel pipes using epoxy resin adhesive. The Adjoint Method is a new joining technique that completely eliminates on-site welding work through a unique adhesive bonding system. By removing the need for welding, the fire risk is reduced, and associated tasks such as complicated fire protection measures and checking for residual flames can be omitted. This significantly improves the construction period and flexibility of the work. In particular, it enables safe and efficient construction in facilities such as factories and warehouses that handle flammable materials, where seismic retrofitting was previously difficult due to fire risks. Additionally, it can accommodate construction during limited hours, such as at night or on holidays, allowing for renovation work to be carried out with minimal disruption to facility operations. 【Features】 - No need for strict fire protection measures since on-site welding is not used. - No bolt holes are made in existing members, preventing cross-sectional loss (minimal hole drilling is required when bonding to the side of square steel pipes). - Since no tensile forces occur at the adhesive joint, high adhesive strength in the shear direction can be expected.
