Pillars made of wood: New wooden hybrid construction method "M-HR Method"
The first floor features a large space constructed using the Summit HR method, while the second and third floors utilize the "2x4 method," achieving a cost-balanced architectural proposal!
We would like to introduce the "M-HR method," a combination of the wooden two-directional frame structure "Summit HR method" and the "Two-by-Four method," which is a combination that has not existed until now. 【Are you giving up on planning like this?】 ◆ You want to create a large open space on the first floor with wooden construction, but you want to keep overall costs down. (Catalog name: M-HR method) ◆ You want to differentiate between wooden frame structures and wall structures in a planar layout. (Catalog name: G frame) By using the Summit HR method to create a large open space on the first floor and employing the "Two-by-Four method" for the second and third floors, we can achieve a balanced architectural proposal in terms of cost! For example, the first floor can be effectively used for stores such as restaurants or parking, while the second and third floors can be proposed for rental offices or multi-family housing. *For more details, please download the PDF.

basic information
■Realization of Large Spaces - The wood-based two-way frame structure "Summit HR Method" by SMB Building Materials Co., Ltd. enables the creation of large spaces without walls. - The joints on the first and second floors utilize GIR joints, which have high pull-out resistance. ■Cost Benefits - By selectively using construction methods according to the application, it is possible to propose buildings with a balanced cost structure. - Compared to mixed structures of RC and steel, the building weight is reduced, allowing for streamlined foundation design. - Being purely wooden, it offers advantages in depreciation periods. ■Seismic Resistance - It has seismic resistance equivalent to that of RC mixed-structure buildings (analyzed by wallstat). ■Contribution to SDGs - By using wood, CO2 emissions during construction are significantly reduced. - Utilization of locally sourced timber is also possible.
