The SpS (SPS) method is a joint construction technique that installs seismic reinforcement members onto existing circular steel pipes (such as columns and truss beams) without welding. It consists of a "reinforcement member joint (non-bonded area)" where the seismic reinforcement member is attached, and "shear resistance areas (bonded areas)" installed on both sides of the reinforcement member joint. These components are attached using specialized half-cylindrical hardware that clamps around the existing circular steel pipe. The stresses generated at the joint are transmitted to the existing circular steel pipe through the shear force at the bonded area, the axial force (tensile and compressive forces) at the reinforcement member joint, and the bending moment at both the reinforcement member joint and the shear resistance area. **Features** - No need for fire protection measures as welding is not used. - No need to drill bolt holes into the existing circular steel pipe. - Construction can be carried out while leaving any irregularities from the existing circular steel pipe. - By separating the bonded and non-bonded areas to distribute stress, it prevents a decrease in adhesive strength due to peeling. *For more details, please contact us or download the catalog to view.*

The Rimtect method is a "roof insulation and waterproofing renovation method" that combines a thermal insulation reinforcement waterproof layer made of special polyurethane with a super weather-resistant heat-insulating paint, designed for aging slate and metal roofs. The materials used possess moderate flexibility and strength, forming a seamless waterproof layer that adheres closely to the substrate. Additionally, because it uses ultra-fast curing resin, it allows for construction to be carried out while the facility remains operational, eliminating the need to stop operations. After repairs, the deteriorated roofing materials are reinforced, enhancing durability and preventing the dispersion of asbestos and other materials, thus contributing to the longevity of the building. 【Features】 ■ Waterproofing and Reinforcement - Utilizes ultra-fast curing polyurethane coating for waterproofing - Forms a seamless waterproof layer with high strength and high elongation, preventing damage from flying objects and reinforcing deteriorated roofs ■ Durability and Safety - The three-layer structure of the renovation layer ensures excellent durability and safety ■ Heat Insulation and Soundproofing - Protective finish with super weather-resistant heat-insulating paint - Insulation and soundproofing effects from high-performance insulation materials - Prevention of condensation and improved durability of roofing materials through the synergistic effects of each layer

This method enhances the rust prevention effect of existing cross-section repair methods by applying ERP rebar rust preventive agent after the rust prevention treatment of rebar corrosion repair methods. The ERP rebar rust preventive agent forms a moisture and chloride penetration suppression layer by being impregnated into the polymer cement-based rust preventive material applied to the rebar. This suppression layer inhibits the intrusion of deterioration factors and improves the rust prevention effect, making it effective for historical buildings with insufficient cover thickness and for the repair of RC structures. This method was developed based on the experience gained from the repair work of the old Shime vertical shaft tower, for which our company was responsible for the structural work, and is suitable for the repair of cultural properties and historical buildings where changes to the external shape are difficult.
