Bringing large wooden spaces closer to you. Using steel materials in appropriate places to achieve both constructability and high strength.

Structural members that combine the workability of wood and the strength of steel. They contribute to the creation of large spaces and the rationalization of design without the use of special construction methods.

The wooden hybrid structural member "TN-WOLSH Series" combines the workability of wood with the strength of steel, allowing for the creation of large spaces without the need for special construction methods, contributing to reduced design loads and streamlined construction processes. By using steel and wood in appropriate locations, it is possible to enhance structural strength while maintaining the workability of wood. The development of dedicated examination sheets and structural data facilitates smooth progress from structural calculations to precut CAD integration. The combination of beams and shear walls enables large space design based on general design knowledge, contributing to improved design efficiency and reduced burden for the introduction of non-residential wooden structures. 【Features】 ■ Hybrid structure that integrates wood and steel ■ Use of steel and wood in appropriate locations while maintaining the workability of wood ■ Fusion of the excellent strength and toughness of steel with the existing wooden design and construction methods ■ Capability to create large spaces without using special construction methods ■ Support for data preparation necessary for structural calculations and CAD integration ■ Lineup includes "TN-WOLSH Beam" and "TN-WOLSH Burring Wall" *For more details, please refer to the materials. Feel free to contact us with any inquiries.

TN-WOLSH Burring Wall <Burring Process>

Adopting a unique surface material! It combines the strength of steel with the properties of wood, ensuring that it does not break even during significant deformations caused by major earthquakes, while maintaining stable performance.

The "TN-WOLSH Burring Wall" utilizes a unique surface material that has undergone burring processing on a 1mm thick thin steel plate, merging the strength of steel with the characteristics of wood. It is a narrow resistance wall that maintains stable performance without destruction even during significant deformations caused by major earthquakes. It employs an open construction method that anyone can use, allowing for on-site cutting of the frame materials. The 1mm burring surface material can be nailed, and the frame materials and wooden structural materials can be screwed together, making the construction method simple and eliminating the need for special design. Additionally, it can be used in both wall-supported and floor-supported configurations, with two internal dimensions between the column materials: 350mm and 335mm. It can accommodate internal dimensions between horizontal members ranging from 1860 to 3340mm, making it suitable for various buildings, including residential and non-residential structures. 【Features】 ■ Wall strength equivalent to 6 times ■ Open construction method usable by anyone ■ Wide range of applicable situations *For more details, please download the PDF or feel free to contact us.

Construction Case: Warehouse Achieving Large Span with Walsh Beams

Wooden axis + lightweight H-shaped steel beam = rationalization! Achieve up to 30% cost reduction and a maximum span of 12m.

We would like to introduce a case where we constructed a warehouse using our "Walsh Beam," achieving a large span. This method realizes an open large space through the fusion of wooden frames and lightweight H-shaped steel. By adopting prefabricated products, we have significantly reduced costs, and the construction method is comparable to conventional wooden structures. We propose "rational" solutions to various challenges in design, structure, manufacturing, and construction. Please feel free to contact us when you need our services. 【Features】 ■ Design: Minimization of ceiling cavity through web penetration holes ■ Manufacturing: Adoption of prefabricated products for significant cost reduction ■ Structure: Reduced examination time using dedicated certification sheets ■ Construction: Construction methods identical to conventional wooden structures *For more details, please download the PDF or feel free to contact us.
