[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portal panel made of laminated wood in which a plurality of boards are laminated with their fiber directions aligned and bonded together.

[0002]

2. Description of the Related Art The inventor of the present application has first disclosed a Japanese Utility Model Application Laid-Open No. 2-1623.
No. 7; "Gate-shaped bearing wall" is devised. This means that in a gate-shaped wall, column base members and beam members
A so-called composite column and composite beam structure in which a frame member and an outer plywood are assembled, and a column base member is formed by combining a sleeve portion and a cantilever portion. Further, the column base member and the beam member are combined with a cantilever beam portion. By attaching and joining gusset plywood over the frame members of the beam and the beam member, the strength and rigidity against horizontal force and vertical force are improved.

[0003]

With such a structure, it is possible to obtain a portal wall having a long span structure. However, there is still a concern that there is insufficient strength at both corners where stress is concentrated by horizontal force. It was desired to develop a structure that would improve the performance.
