(A) is a front view, (B) is a side view, FIG. 5 is a perspective view showing an intermediate hardware, and FIG. 6 is a perspective view showing a connection structure of a portal bearing wall and a floor structure. FIG. 7 is a perspective view showing a connection structure between the portal bearing wall and the foundation.

  A building 1 shown in FIG. 1 is a unit building constructed by adjoining a plurality of factory-produced building units 2 on a foundation 3 provided at a construction site, and a part of the building is a floor wall. It has a unit 10.

  As shown in FIG. 2, the floor-equipped wall unit 10 is a unit in which a floor structure 20 and a portal load-bearing wall 30 having a wooden ramen structure are integrated in advance at the factory production stage. The column base of the portal load bearing wall 30 is connected to an intermediate hardware 40 built in the floor structure 20. And the building 1 installs the floor structure 20 on the foundation 3 as a lower structure with respect to the floor-equipped wall unit 10, mounts the left and right column bases of the portal bearing wall 30 on the floor structure 20, The wall frame 31 and the foundation 3 of the portal load bearing wall 30 are connected via an intermediate hardware 40. In the building 1, a space between the left and right wall frames 31 of the portal load bearing wall 30 on the floor structure is a large opening such as a window.

  As shown in FIGS. 2 and 3, the floor structure 20 is configured by attaching a wooden base 22 to the lower surface of a floor frame assembly 21 made of a wooden joist 21 </ b> A and attaching a floor material 23 to the upper surface of the floor frame assembly 21.

  As shown in FIGS. 2 to 4, the portal bearing wall 30 forms a wall frame 31 with a wooden structure column 31 </ b> A and a wooden vertical frame member 31 </ b> B, and both ends of the wooden structure beam 32 at the upper ends of the left and right wall frames 31. Are rigidly joined to form a gate. As shown in FIG. 4, the wall frame 31 and the structural beam 32 are formed with grooves 33A and 33B at the widthwise central portions of the upper end portion of the structural column 31A and the end portion of the structural beam 32 that intersect each other. The metal piece 34 is inserted into the grooves 33A and 33B, and the upper end portion of the structural column 31A and the L-shaped joint metal piece 34 inserted into the groove 33A are joined by the drift pin 35A, and the end portion of the structural beam 32 and The L-shaped metal fitting 34 inserted into the groove 33B is joined by the drift pin 35B. As a result, the left and right structural columns 31A, by extension, the wall frame 31 and the structural beam 32 are rigidly joined to form a portal bearing wall 30 having a wooden frame structure.

  Note that the portal load bearing wall 30 has a wooden lower frame member 36 laid over the lower end surfaces of the left and right wall frame assemblies 31 and a wooden upper frame member 37 laid over the upper end surfaces of the left and right wall frame assemblies 31. The portal bearing wall 30 in the production stage is stabilized by connecting the left and right wall frames 31 with a lower frame member 36. In the lower frame member 36, after the floor structure 20 and the gate-type load bearing wall 30 are integrated, portions corresponding to the inner dimensions of the left and right structural columns 31 </ b> A are cut off.

  The floor structure 20 and the portal bearing wall 30 are connected and integrated by the following structure. In the floor structure 20, as shown in FIG. 3, the intermediate hardware 40 is disposed on the lower side of the floor surface material 23 corresponding to the column bases of the left and right structural columns 31 </ b> A and the vertical frame material 31 </ b> B of the portal bearing wall 30. Then, the intermediate hardware 40 is fixed to the joists 21 </ b> A of the floor frame 21 with the wood screws 41. As shown in FIG. 5, the intermediate metal piece 40 includes a connecting plate 40 </ b> C between the upper plate 40 </ b> A and the lower plate 40 </ b> B, and the connecting plate 40 </ b> C is fixed to the joists 21 </ b> A by the wood screws 41. On the other hand, in the portal bearing wall 30, as shown in FIG. 3, the attachment plate 50A of the pulling metal object 50 is fixed to the side surfaces of the legs of the left and right structural columns 31A (the same applies to the vertical frame member 31B) with bolts 51 and nails 52. To do. The left and right structural pillars 31A (the same applies to the vertical frame member 31B) of the portal load bearing wall 30 are placed on the floor structure 20, and the bolts 61 are drawn as shown in FIG. Via the holes provided in the lower frame member 36 of the portal load bearing wall 30 and the floor member 23 of the floor structure 20, the bolt insertion hole of the upper plate 40 </ b> A of the intermediate hardware 40 corresponding to the leg portion of the structural column 31 </ b> A. The nut 61A is fastened to the insertion end. Thereby, the floor-equipped wall unit 10 in which the floor structure 20 and the gate-type load-bearing wall 30 (the structural pillar 31A and the vertical frame member 31B) are connected is formed.

  The portal bearing wall 30 and the foundation 3 are connected by the following structure. When the floor structure 20 of the floor wall unit 10 is installed and installed on the foundation 3, as shown in FIG. 7, the anchor bolt 4 of the foundation 3 is connected to the gate structure via the hole provided in the base 22 of the floor structure 20. The structural pillar 31A of the load bearing wall 30 and the vertical frame member 31B are inserted into the bolt insertion holes of the lower plate 40B of the intermediate hardware 40 corresponding to the legs, and the nut 4A is fastened to the insertion end. As a result, the left and right structural columns 31 </ b> A of the portal bearing wall 30 and the leg portions of the vertical frame member 31 </ b> B are connected to the foundation 3 through the attracting hardware 50 and the intermediate hardware 40.
