ナカムラ List of Products and Services

The "NK Method" is a wooden construction technique that uses a uniquely developed seismic joint hardware called "NK Hardware" to achieve large spans and spacious interiors. By combining precut building materials with panel construction, it contributes to cost reduction and shortened construction periods. Using high-rigidity portal frames makes it easy to create large openings similar to steel and reinforced concrete structures. This method allows for highly flexible wooden construction designs without partitions, applicable not only to residential buildings but also to non-residential structures such as daycare centers, welfare facilities, and stores or warehouses. 【Features】 ■ Structural calculations (allowable stress calculations) are conducted for all buildings, with free structural proposals available. ■ A consistent system is established from structural design to precut material delivery. ■ There are no partitions, allowing for unlimited future layout changes. *For more details, please refer to the materials. Feel free to contact us with any inquiries.

• Systems Architecture

Our company supports design from the planning stage using the "NK Method Precut System," which includes allowable stress calculations, high seismic joint hardware, and laminated timber, contributing to the realization of wooden structures for various buildings such as residential homes, commercial facilities, and welfare facilities. - Is the proposed plan feasible in wood construction? - Is it structurally possible with the current span? - I want to change from steel or reinforced concrete to wood! - I want more freedom in design with wood! For concerns like the above, our "NK Method" offers free allowable stress calculations and proposals from the planning stage. *For more detailed information about the NK Method, please download the PDF or feel free to contact us.*

• Systems Architecture

In the "NK Method," we conduct allowable stress calculations for the entire building to ensure safety. The high seismic performance is proven through full-scale vibration tests. It is now possible to construct wooden buildings with large spans and large spaces, which were previously considered impossible. Additionally, by combining pre-cut materials with panel construction using seismic hardware, we achieve simplified work processes and a uniform finish that is not dependent on the carpenter's skill level. 【Features】 ■ Seismic connection hardware and laminated wood overcome the weaknesses of seismic forces ■ Significant cost reduction and shortened construction period ■ Achieving large openings and built-in features with a portal frame *For more details, please download the PDF or feel free to contact us.
