日本CLT技術研究所 List of Products and Services

The "Japan CLT Technology Research Institute" is a franchise network headquarters operated by our company, established for the purpose of promoting the use of buildings utilizing CLT and developing technology. By utilizing CLT, which is made from the great blessings of nature, we are shifting from selling products to selling experiences. Through forward-looking architecture, we will create new urban landscapes together. We provide member companies with technical know-how related to CLT construction, CLT panels, original hardware, and structural calculation services using our uniquely developed structural calculation system. 【Overview】 ■ Organization Name: Japan CLT Technology Research Institute ■ Established: April 1, 2018 ■ Location: Okayama Office, 2-9-11 Nakasendo, Kita-ku, Okayama City, Okayama Prefecture *For more details, please refer to the external link or feel free to contact us.

The "NCL Soundproof Floor Specification" is an original soundproof floor made using CLT panels. One of the sources of trouble in apartment buildings is the noise from daily activities between floors. This includes heavy impact sounds like "thuds" caused by children jumping or walking, as well as lighter impact sounds from dropping light objects or dragging chairs. With this floor specification, compared to standard CLT panels, it demonstrates approximately twice the effectiveness against heavy impact sounds and about ten times the effectiveness against light impact sounds, enabling a comfortable living environment. 【Features】 ■ Approximately twice the effectiveness against heavy impact sounds and about ten times against light impact sounds compared to standard panels. *For more details, please refer to the external link page or feel free to contact us.

The "LC-core construction method" efficiently arranges CLT panels while maintaining seismic performance and reducing the amount of panel usage. In a shaking table experiment conducted in October 2017, we carried out seismic tests using various cases that included seismic waves from the Hanshin Earthquake. No destruction of original hardware or original CLT panels was observed, demonstrating high durability. Additionally, in July 2018, a second shaking table experiment was conducted, confirming the maximum strength of the original hardware and original CLT panels. 【Features】 ■ Compared to CLT panel construction methods, the amount of wall panels can be reduced by 50%. ■ With a reduced amount of required walls, the design and proposal flexibility increases (such as fully glass-clad CLT buildings). ■ Strong connections using original hardware can achieve high seismic resistance even with reduced CLT panel usage. *For more details, please refer to the external link page or feel free to contact us.

CLT, or Cross Laminated Timber, is a large panel made by stacking layers of laminated boards with their grain direction oriented perpendicular to each other and glued together. It is a new wood-based structural material that has been developed primarily in Austria since the mid-1990s. Today, it is being used in various buildings across European countries, and in North America and Oceania, standardization and factory production have begun, showing rapid expansion worldwide. In Japan, it is gaining attention as a new structural material to replace traditional wooden construction methods, steel frame construction, and reinforced concrete construction. It is rapidly developing as a key solution for the effective utilization of domestic timber, with collaboration between the public and private sectors. *For more details, please refer to the PDF materials or feel free to contact us.
