Abstract: A floor panel joint structure and a method of constructing a wooden building with the same are provided. The method comprises mounting floor panels on the foundation, and, joining a group of structural units to the foundation to produce a first floor structure. This is followed by mounting on the structural units at the first floor another group of structural units having a second floor structure made of floor panels joined to each other by panel joiners. The second floor structure are joined to top beams of the structural units at the first floor by through bolts which extend vertically across the floor panel, panel joiner, and beam. A roof structure is fabricated by joining roof panels to purlins. The purlin has a rib provided on a lower side thereof for connecting to the beams by a length of plywood boards. Accordingly, the installation of the floor and roof structures is simplified and its physical strength will be increased.

Abstract: A structural member, a floor structure, and a roof structure for a wooden building, and a method of building with the same are provided. The method comprises mounting floor panels on a foundation, mounting on sills wall panels provided with L shaped pillars of a plywood laminated material to produce a wall structure of the first floor, mounting and joining second-floor panels by panel support assemblies to the first-floor wall structure, and joining the second-floor panels with their beams connecting to each other to produce a floor structure of the second floor. This is followed by assembling a wall structure of the second floor, joining roof panels to each other by retainer assemblies on a ridge beam, and joining the roof panels with arms connecting to each other to produce a roof structure. Accordingly, the steps of making the floor, wall, and roof structures are minimized in number.
