The "Ridabble Method" is a reinforcement technique that uses carbon fiber sheets, carbon fiber plates, and specialized anchoring hardware (cast steel plates) to shear-reinforce the cut-out sections of existing beams, allowing them to achieve a load-bearing capacity equal to or greater than that of the beams before the openings. This method has obtained general evaluation certification. Unlike traditional anchoring methods using L angles or flat bars for carbon fiber sheets, this method is compact and simple, yet ensures reliable anchoring of the carbon fiber sheets. There are two types of anchoring plates: flat type and vertical type, which can also be applied to reinforcement of wall-mounted columns and T-shaped beams. 【Features】 ■ A method that has obtained general evaluation certification for opening reinforcement General evaluation (Public Interest Incorporated Foundation) Better Living CBL RC001-10 ■ Suitable for opening reinforcement due to equipment renewal ■ Allows for pseudo-closed reinforcement through the use of anchoring hardware ■ Applicable to underground beams as well *For more details, please refer to the PDF materials or feel free to contact us.

The "e-plate method" is a bending reinforcement technique that involves attaching CFRP sheets to the surface of existing beams and slabs using a highly viscous putty-like epoxy resin adhesive, thereby enhancing the bending strength or bending stiffness of the components. Due to its excellent strength and stiffness, it is not necessary to apply it over the entire surface, which reduces dust generation during construction. There are two types of CFRP sheets: high-strength (GM) type with different tensile strength and elastic modulus, and high-stiffness (HM) type. The two types are selected based on the target bending strength and bending stiffness for reinforcement. ★2023 VR Exhibition Archive Now Available★ We present an overview of Constec HD's maintenance and preservation technologies for architecture and civil engineering.

Many factories cannot stop their operating production lines for long periods. Therefore, seismic reinforcement and large-scale renovation work come with many difficulties. Constec has a wealth of experience in building maintenance and preservation work. Utilizing the technologies and know-how we have cultivated so far, we provide safety and peace of mind for factories, from investigation and diagnosis to reinforcement design and construction. ☆Technologies under development in 2022 Joining reinforcement materials without welding. Suitable for properties where open flames are prohibited. 【SpS Method】 This is a joining method that attaches seismic reinforcement materials to existing circular steel pipe members without welding. It clamps the existing steel pipe members with dedicated hardware and integrates them using adhesives and fillers. The seismic reinforcement materials can be applied to steel frames, braces, and struts, and can be installed on one side or both sides. Target: Steel pipe trusses and steel pipe columns 【Welding-free joining method for H-shaped steel】 This is a joining method that installs braces and strut reinforcement materials on existing H-shaped steel and square steel pipes without welding. It uses adhesives and bolts for joining. Since it does not require drilling holes in the structure, the construction is simple and does not damage the structure. Target: H-shaped steel columns and beams, square steel pipe columns

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.*

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.

The e-anchor is a CFRP molded product that combines a plate part and a strand part using a unique molding technology, serving as a fixing body for the end anchoring of the e-plate method. By inserting the strand part into the concrete hole and adhering the plate part to the e-plate, the end anchoring of the e-plate is achieved. The strand part remains flexible until the curing of the adhesive resin, making it easy to adjust the angle during construction. Additionally, the e-anchor is only 3mm thick, allowing for a step height of about 10mm after installation. Compared to methods that mechanically anchor the ends using steel plates or bolts, it minimizes interference with the finishing. 【Features】 - The e-anchor has a small thickness and minimal interference with the finishing. - Being a highly durable CFRP molded product, it does not suffer from corrosion or similar issues. - It allows for easy angle adjustments during construction.
