Ceiling Seismic Reinforcement System "TEC Method (Horizontal Reinforcement Specification)"

Ceiling Seismic Reinforcement System "TEC Method (Horizontal Reinforcement Specification)"

By applying horizontal reinforcement, we secure 9000N! It is also compatible with ceilings exceeding a hanging length of 1500mm.

In natural disasters, buildings may appear to have minimal external damage, but issues arise from damage caused by ceiling collapses in the interior. The "TEC Method (Horizontal Reinforcement Specification)" can ensure the same horizontal reinforcement capacity of 9000N even for ceilings with a suspension length exceeding 1500mm by applying horizontal reinforcement. Additionally, the original scaffolding material allows for easy inspection work within the ceiling. 【Features】 ■ Uses square pipes (32×14×1.6) for the furring channels and brace materials ■ Can be used for ceilings exceeding 20kg/m2 (including finishing materials) ■ The original scaffolding material enables easy inspection work within the ceiling ■ The placement of braces is arranged along the extension line of the lower horizontal reinforcement braces ■ The ends of the horizontal reinforcement are secured to the structural members of the perimeter *For more details, please refer to the PDF document or feel free to contact us.

Seismic construction material "Seismic Cable Brace" *Construction results and technical documents available.

Seismic construction material "Seismic Cable Brace" *Construction results and technical documents available.

Compared to conventional brace materials, the strength is about five times greater, and the weight is about one-fifth. Lightweight, fast, and safe! Introducing high-strength, lightweight, and compact seismic reinforcement materials!

The "Seismic Cable Brace" is a reinforcement material made from high-strength PC steel wire, widely used as PC tensioning material for condominiums and bridge girders. Compared to conventional brace materials, it has approximately five times the strength, about one-fifth the weight, and a diameter of less than half, while maintaining an equivalent elastic modulus, offering numerous advantages. It has no initial elongation and immediately demonstrates its effectiveness during an earthquake. 【Features】 ■ High-strength wire used for brace materials ■ Diameter can be selected according to the required seismic performance ■ Compact terminal fittings ■ Safe and secure seismic reinforcement method *For more details, please refer to the PDF document or feel free to contact us.

Seismic reinforcement of wooden houses

Seismic reinforcement of wooden houses

Utilizing technology and experience to promote seismic reinforcement of houses built based on old laws!

At NITTOH Corporation, we are promoting seismic reinforcement of houses built under old laws by utilizing our technology and experience, and we offer "Seismic Reinforcement for Wooden Houses." We perform efficient seismic reinforcement through a combination of methods such as reinforcement with structural plywood, partial opening plywood reinforcement, bracing methods, reinforcement of the underfloor and wooden framework with hardware, and repairs of decayed or termite-damaged areas. Please feel free to consult us for more details. 【Features】 ■ Reduces demolition, removal, disposal, and restoration (which accounts for two-thirds of construction costs) ■ Balanced reinforcement ■ Utilization of various techniques ■ Recommendation for simple renovations (there is no need to strictly adhere to a 1.0 standard) *For more details, please refer to the PDF materials or feel free to contact us.

Advanced technology to protect buildings: Seismic reinforcement using epoxy resin and fiber sheets.

Advanced technology to protect buildings: Seismic reinforcement using epoxy resin and fiber sheets.

By injecting resin deep into the wood and using aramid fiber sheets in conjunction, the adhesive strength and reinforcement strength of the wood are significantly improved.

Modern architectural technology is increasingly emphasizing the importance of seismic design in response to growing demands for safety and sustainability. The aging deterioration of structural materials, particularly termite damage and wood decay, can have serious impacts on the structural stability of buildings. To address these issues and maintain the seismic resistance of structures, the application of innovative repair techniques is essential. *For more detailed information, please refer to the related links. You can download the PDF for more details or feel free to contact us.*

Ceiling Seismic Reinforcement System 'TEC Method (Standard Specification)'

Ceiling Seismic Reinforcement System 'TEC Method (Standard Specification)'

Supports horizontal strength of 2.2G! Ensures horizontal reinforcement capacity of 9000N! Safe and secure with industry-leading strength!

In natural disasters, buildings can suffer damage that may not be apparent from the outside, but issues arise from interior damage due to ceiling collapses. The "TEC Method (Standard Specification)" meets the standards set forth by the "Ministry of Land, Infrastructure, Transport and Tourism Notification No. 71" promoted by the government and is designed to withstand a horizontal seismic intensity of 2.2G. It has a horizontal reinforcement capacity of 9000N, which is among the highest in the industry. 【Features】 - Uses square pipes (32×14×1.6) for the furring strips and brace materials - Can be used for ceilings exceeding 20kg/m2 (including finishing materials) - Original scaffolding materials allow for easy inspection work within the ceiling - Limits the length of hanging bolts to within 1500mm *For more details, please refer to the PDF materials or feel free to contact us.

Seismic retrofitting of drainage pipe openings (small to medium diameter) - "Magma Rock Method mini・NGJ"

Seismic retrofitting of drainage pipe openings (small to medium diameter) - "Magma Rock Method mini・NGJ"

Non-excavation sewer pipelines (small to medium diameter, φ200 to φ700) seismic resistance technology. Equipped with cylindrical stainless steel and rubber sleeves to withstand Level 2 seismic motion.

This is a non-excavation seismic reinforcement method developed to enhance the seismic resistance of the "pipe connection section where existing pipes and manholes connect," targeting pipe diameters of Ø700 or less. In cases where the connection between the manhole and the pipe does not have a flexible structure, it is known that this connection section, being in a semi-rigid state, tends to concentrate damage such as circumferential cracks or breakage when subjected to significant loads during an earthquake. This method involves pre-cutting grooves (joints) at the connection between the main pipe and the manhole, installing a mini magma, and concentrating seismic stress here to induce cracking at the joint, thereby preventing damage to the connection through its shock absorption effect. The mini magma, which is pre-installed at the locations where cracks occur along the joint, prevents the inflow of groundwater and soil into the pipe. Additionally, this seismic reinforcement method can be reliably installed even when the existing pipe is in a flowing state, as long as the water depth is 25% or less of the nominal diameter, targeting the connection between the manhole and the pipe. [Applications] ● Seismic reinforcement of the connection between manholes and pipes (circular pipes)
