Large Space without Columns Formed by Thick Bonded Wood
This house is structured with six pieces of RC wall panels and a lattice-like large timberwork formed by 16 pieces of bonded wood members with a large cross-section (Japanese larch,210×2,100mm) placed on top of the walls. By configuring bonded wood members with a large cross-section (2,100mm beam depth) into a reciprocal frame structure supported by two 75×75mm steel columns, it enabled a large cantilever even in an area with heavy snowfall. Under the eaves is an 8×5m garage with no columns. Moreover, six pieces of RC wall panels with the capability to resist seismic forces enabled a full opening to view the Tateyama Mountain Range.
In order to present the timberwork of bonded wood members with a large cross-section in an exposed structure except for its outer periphery, they employed Stroog.LSB and Node.Seam connectors which are completely hidden including pin holes and slits, also allowing for the detail that hides connectors in the joints between 75×75mm steel columns and bonded wood members. At the same time, the timberwork can be constructed by simply inserting a bonded wood member down into another, providing higher constructability.
Joints between RC wall panels and bonded wood members with a large cross-section use Node.RC connectors and Stroog.LSB to bear the vertical load with local compression of the timber and Stroog.LSB. In addition, extremely thin Stroog.LSB with Φ12mm realized the neat joints between curtain wire rods and bonded wood members with a large cross-section.
