Structural member, floor structure, and roof structure for wooden building and a method of building with the same

A structural member for a wooden building comprising:

• a pair of elongated members formed of a plywood laminated material including a plurality of plywood boards laminated to each other, each of said elongated members having face surfaces and elongated edge surfaces;
• and
• said elongated members being joined to each other by bond fitting one of said elongated edge surfaces of one of said elongated members into a recess provided in one of said face surfaces of another one of said elongated members so that laminating directions of the two plywood laminated materials are perpendicular to each other;
• and
• said recess having bottom and opposing side surfaces defined by a portion of said plurality of plywood boards.

• and
• a strip member embedded at a right angle to and in a substantially center region of an interfacebetween the pair of elongated members and extending into said one of said elongated edge surfaces and into a bottom surface of said recess to supplement said bond between the pair of elongated members.

A floor and wall structure for a wooden building comprising:

• first and second panel support assemblies each including:
• a first group of beam members formed of plywood laminated materials including a plurality of sheet plywood boards bonded one over the other;
• a second group of beam members formed of said plywood laminated materials;
• said first group of beam members being oriented horizontally and alternately interposed between and at right angles to center regions of said beam members of said second group, said first and second group of beam member being joined with through bolts to form a sideways oriented T-shaped structure;
• first and second walls each having a spaced apart double plywood board structure and which are interposed between pillars of the building;
• a floor panel including:
• an upper surface board;
• a lower surface board;
• and
• a set of beams space apart and sandwiched between the upper and lower surface boards and having a length equal to a width of the two surface boards, said set of beams being space apart a distance corresponding to a width of said first group of beam members and having a width corresponding to a spaced apart distance of said first group of beam members to permit a fitted engagement of said set of beams and said first group of beam members;
• said first panel support assembly having said first group of beam members extending between said set of beams and fixed thereto with through bolts and said second group of beam members extending vertically downward into a space defined by said space apart double board structure of said first wall and fixed thereto;
• said second panel support assembly having said first group of beam members horizontally extending in a fitted engagement between said upper and lower surface boards of said floor panel at a portion thereof absent said set of beams and fastened thereto, and said second group of beam members extending vertically downward into a space defined by said space apart double board structure of said second wall and fixed thereto;
• and
• said floor panel being connectable to another floor panel by joining ends of said set of beams opposite said first panel support assembly to corresponding beams of another floor panel with metallic beam connectors.

A roof structure for a wooden building comprising:

• a ridge beam having retainer assemblies mounted thereon, the retainer assemblies including:
• v-shaped beam members formed of plywood laminated materials including a plurality of sheet plywood boards bonded one over the other;
• and
• said ridge beam having sets of said v-shaped beam members fix thereto in an inverted v orientation, said v-shaped beam members of said sets being spaced apart a first predefined distance and said sets being spaced apart a second predefined distance;
• a roof panel including upper and lower surface boards and a set of beams spaced apart and sandwiched between the upper and lower surface boards, said beams being spaced apart a distance corresponding to a width of said v-shaped beam members and having a width corresponding to said first predefined distance to fittingly engage said sets of v-shaped beam members, and having a length equal to a width of the upper and lower surface boards;
• a wall having a double plywood board structure and interposed between two pillars of the building, and a joiner assembly including vertical beam members extending upwards from said wall and disposed to fittingly engage said set of beams of said roof panel in an interleaved engagement for joining the roof panel to the wall;
• said set of beams being joined to said v-shaped beams members of the retainer assembly and said vertical beam members of said joiner assembly with through bolts so that the roof panel is installed on the ridge beam and the wall;
• and
• said roof panel being connectable to another roof panel by joining said set of beams to corresponding beams of the other roof panel with metallic beam connectors.
