Five Advantages of the Seismic Retrofit Construction "JSPAC Method"

Five Advantages of the Seismic Retrofit Construction "JSPAC Method"

Exhibits excellent performance in terms of seismic resistance, construction period, and cost! Suitable for all types of concrete buildings.

The "JSPAC method" is a next-generation seismic reinforcement technique developed as an easy and advanced reinforcement method suitable for all types of concrete buildings. This method solves challenges by achieving construction in a compact space compared to previous methods. Ensuring safety during construction has also become easier, allowing for work to be done while the building is in use. Additionally, since construction can be tailored to the shape of various parts of the building, it can be applied to a wide range of structures, including apartments, office buildings, and school buildings. While it is often applied to concrete columns, it can also be adapted to structures such as steel frames depending on the situation. **Five Advantages** - Construction can be carried out while the building is occupied. - Capable of accommodating diverse types of buildings. - Minimal impact on the building's design. - Excellent seismic performance with minimal construction. - Can be executed at a lower cost and with energy savings compared to conventional methods. *For more details, please refer to the PDF document or feel free to contact us.*

Bridge pier seismic reinforcement method "AT Method"

Bridge pier seismic reinforcement method "AT Method"

Extremely suppress the bending moment to reduce the increase in the cross-section of the structure, while also accommodating constraints from adjacent structures!

The "AT Method" is a seismic reinforcement method for bridge piers that significantly reduces the thickness of the reinforcement wrapping compared to the RC wrapping method and conventional PCM wrapping method. By cutting grooves into the surface of the existing concrete and embedding reinforcement bars, the increase in wrapping thickness can be greatly reduced. As a result, the range of applicability expands even in cases with structural constraints. 【Construction Procedure】 ■ Surface treatment → Core space cutting → Core drilling → Embedded groove cutting → Reinforcement bar embedding commencement → Band reinforcement bar installation → Protective coating → Finish material application *For more details, please feel free to contact us.

Hybrid seismic reinforcement method

Hybrid seismic reinforcement method

It is a seismic resistance construction method that joins seismic braces using epoxy resin and anchors in two different ways.

Compared to conventional methods, the number of post-installed anchors can be reduced, and since roughening of the existing structure is unnecessary, noise, vibration, and dust can be minimized, allowing for construction while remaining in the building. By adjusting the number of post-installed anchors on the existing framework, reinforcement effects can be secured as needed. Due to the indirect connection with head-mounted studs, the lap length can be reliably secured, ensuring high quality. This method can also be used as a steel brace with openings.

Seismic reinforcement method "E-Brace" [Anchorless method that is economical and has a short construction period]

Seismic reinforcement method "E-Brace" [Anchorless method that is economical and has a short construction period]

Economic anchorless seismic reinforcement method! Significantly reduces construction noise and vibration, and also shortens the construction period!

"E-Brace" is a simple seismic retrofitting method that integrates framed steel braces and bag-shaped fiber forms within the framework of buildings constructed with reinforced concrete (RC) or steel-reinforced concrete (SRC). Since it does not require post-installed anchors, it significantly reduces construction noise and vibration, allowing for work during business hours and at night. Additionally, it eliminates the need for traditional formwork removal, enabling both a reduction in construction time and costs. 【Features】 ■Significantly reduces construction noise and vibration ■Shortens construction period ■Reduces construction costs ■Resistant to recurring major earthquakes *For more details, please request materials or view the PDF data available for download.

Bridge pier seismic reinforcement method "SR Shotcrete Method"

Bridge pier seismic reinforcement method "SR Shotcrete Method"

Reinforcement method for existing RC bridge piers using special polymer cement mortar spraying for seismic strengthening.

The "SRShotcrete Method" is a technique that enhances seismic performance by spraying a special polymer cement mortar to integrate with existing RC bridge piers. It can be applied to bridge piers where wrapping with RC methods exceeds the construction limits and riverbed obstruction rates, or where increased load on the pier foundation is a concern, by wrapping with a thickness of 250mm or more. By using a special polymer cement mortar that has superior strength characteristics and durability compared to concrete as the wrapping material, it is possible to reduce the wrapping thickness to about 1/5 of that of conventional RC wrapping methods. 【Features】 ■ Construction can be performed without increasing the width of the bridge pier ■ Stable construction over a wide area can be achieved in a short time ■ Fast construction speed reduces the construction period and offers excellent cost-effectiveness ■ Excellent filling performance ■ Superior adhesion to existing concrete *For more details, please download the PDF or feel free to contact us.
