Both ends of floor beam 25 are fixed to steel columns 21 and 23, respectively, and floor beam 25 is erected horizontally between steel columns 21 and 23. Floor beam 25 is fixed to foundation 10. Other floor beams are erected similarly between the steel columns. Sub-floor beams may also be erected between the floor beams.

[0052] (3) Installation of the foundation Next, the base 31 is placed on the floor beam 25 with the base 31 parallel to the floor beam 25. The base 31 is fixed to the floor beam 25 with fasteners.

[0053] (4) Installation of joint fittings Next, the joint fitting 50 is fixed onto the base 31. Specifically, the base plate 51 of the joint fitting 50 is placed face down on the base 31, and the insert plate 52 of the joint fitting 50 is stood upright against the upper surface of the base 31, and the base plate 51 is fixed to the base 31. The timing for attaching the joint fitting 50 to the base 31 may be any time before erecting the wooden posts 41, 46 described below.

[0054] (5) Erection of ceiling beams Next, as shown in Figure 7, the ceiling beam 27 is lifted up by a crane or the like and placed between the steel frame columns 21 and 23. Both ends of the ceiling beam 27 are fixed to the steel frame columns 21 and 23, respectively, and the ceiling beam 27 is erected horizontally between the steel frame columns 21 and 23. Similarly, the other ceiling beams are erected between the steel frame columns. Small ceiling beams may also be erected between the ceiling beams. The ceiling beam 27 may also be erected before the foundation 31 is installed.

[0055] (6) Installing the angle Next, as shown in Figure 8, the web 61 of the angle 60 is placed against the underside of the ceiling beam 27, and the web 62 of the angle 60 is hung down from the underside of the ceiling beam 27. The web 61 is joined to the ceiling beam 27 by welding or high-strength bolts, etc. The web 62 of the angle 60 corresponds to the flange 63. The angle 60 may be joined to the ceiling beam 27 before the ceiling beam 27 is erected. The angle 60 may also be joined to the ceiling beam 27 in advance, for example in a factory, before the ceiling beam 27 is delivered.

[0056] (7) Installing wooden pillars Next, the wooden pillars 41 are erected between the floor beams 31 and the ceiling beams 27.

[0057] Specifically, first, the insert plate 52 of the joint fitting 50 is inserted into the slit 42 of the wooden post 41. At this time, the slit 42 and the insert plate 52 are movable relatively in the in-plane direction (the in-plane direction refers to the direction parallel to the insert plate 52), so the insert plate 52 of the joint fitting 50 can be inserted into the slit 42 of the wooden post 41 even if the wooden post 41 is tilted with respect to the vertical direction. Also, because the slit 42 opens not only at the bottom end of the wooden post 41 but also on the side, the insert plate 52 of the joint fitting 50 can be inserted into the slit 42 of the wooden post 41 even if the wooden post 41 is tilted with respect to the vertical direction.

[0058] Next, the posture of the wooden pillar 41 is adjusted so that the wooden pillar 41 stands vertically on the base 31. When the wooden pillar 41 stands on the base 31, the upper part of the wooden pillar 41 abuts against the flange 63. Next, the wooden post 41 is joined to the base 31 via the joint fitting 50 by inserting the connector 55 into the insertion hole 43 of the wooden post 41 and the through hole 53 of the insert plate 52 . Next, the upper part of the wooden post 41 is joined to the flange 63 with fasteners 65 such as screws.

[0059] The wooden pillar 46 is erected in the same manner as the wooden pillar 41.

[0060] (8) Wall installation Next, wall 70 is installed in the area enclosed by wooden pillars 41, 46, floor beams 25, and ceiling beams 27. Specifically, wall panel 71 is lifted using a crane or the like, and fitted into the area enclosed by wooden pillars 41, 46, floor beams 25, and ceiling beams 27. At this time, side member 72 of wall 70 is overlapped with side member 44 of wooden pillar 41 in the wall thickness direction (width direction of beams 25, 27), side member 72 of wall 70 is overlapped with side member 49 of wooden pillar 46 in the wall thickness direction, and the upper part of wall 70 is abutted against flange 63. Side member 44 of wooden pillar 41 is joined to side member 72 of wall 70 with adhesive or screws, and side member 49 of wooden pillar 46 is joined to side member 73 of wall 70 with adhesive or screws, the upper part of wall 70 is joined to flange 63 with screws, and the lower part of wall 70 is joined to base 31.

[0061] Next, a wall 80 is installed in the area enclosed by the steel column 21, the wooden column 41, the floor beam 25, and the ceiling beam 27 (see FIG. 1). Furthermore, a wall 80 is installed in the area enclosed by the steel column 23, the wooden column 46, the floor beam 25, and the ceiling beam 27 (see FIG. 1).

[0062] Wooden columns and walls are installed in other openings in the rigid frame structure, the first floor floor is laid, and the first floor ceiling is installed. The second and third floors of the framework 1 are constructed using wooden construction methods such as the conventional post and beam method, the wood panel adhesive method, or the wooden frame wall method.

[0063] 3. Technically advantageous effects (1) Even if the upper ends of the wooden columns 41, 46 do not stably abut the underside of the ceiling beam 27 due to an error in the length of the wooden columns 41, 46 relative to the distance between the ceiling beam 27 and the foundation 31, the flanges 63 are joined to the underside of the ceiling beam 27, the flanges 63 hang down from the ceiling beam 27, and the sides of the wooden columns 41, 46 abut against and are joined to the flanges 63, so the wooden columns 41, 46 are joined to the previously erected ceiling beam 27. Therefore, the skeleton 1 and its construction method are suitable for later erecting the wooden columns 41, 46 under the previously erected ceiling beam 27. The joint structure and manufacturing method between the wooden column 41 and the ceiling beam 27 are also suitable for later erecting the wooden column 41 under the previously erected ceiling beam 27. The joint structure and manufacturing method between the wooden column 46 and the ceiling beam 27 are also suitable for later erecting the wooden column 46 under the previously erected ceiling beam 27.

[0064] (2) Because the ceiling beam 27 is erected before the wooden columns 41, 46 are erected, in order for the wooden columns 41, 46 to be securely positioned between the ceiling beam 27 and the foundation 31 after the ceiling beam 27 is erected, the length of the wooden columns 41, 46 needs to be slightly shorter than the distance between the ceiling beam 27 and the foundation 31. Even in this case, the flange 63 hangs down from the ceiling beam 27, and the sides of the wooden columns 41, 46 abut against and are joined to the flange 63, so the wooden columns 41, 46 are joined to the ceiling beam 27 that was erected earlier. In other words, even if the upper ends of the wooden columns 41, 46 are slightly separated from the underside of the ceiling beam 27, the flange 63 contributes to fixing the wooden columns 41, 46 to the ceiling beam 27.

[0065] (3) When attaching the angle 60 to the ceiling beam 27, the web 61 of the angle 60 comes into surface contact with the underside of the ceiling beam 27 and is joined to the underside of the ceiling beam 27, stabilizing the posture of the web 62 of the angle 60, i.e., the flange 63. The stability of the posture of the flange 63 contributes to the stability of the posture of the wooden columns 41, 46. Therefore, when the wooden columns 41, 46 are later erected below the ceiling beam 27 that has been previously erected, the upper parts of the wooden columns 41, 46 are stably joined to the ceiling beam 27.

[0066] (4) When erecting the wooden pillar 41, the slit 42 and the insert plate 52 can move relatively in the in-plane direction (the in-plane direction refers to the direction parallel to the insert plate 52), so the insert plate 52 of the joint fitting 50 can be inserted into the slit 42 of the wooden pillar 41 even if the wooden pillar 41 is at an angle to the vertical direction. Furthermore, because the slit 42 opens not only at the bottom end of the wooden pillar 41 but also on the side, the insert plate 52 of the joint fitting 50 can be inserted into the slit 42 of the wooden pillar 41 even if the wooden pillar 41 is at an angle to the vertical direction. Therefore, even if the length of the wooden pillar 41 is equal to the distance between the ceiling beam 27 and the foundation 31, the wooden pillar 41 can be easily erected between the ceiling beam 27 and the foundation 31.

[0067] (5) The upper part of the wooden pillar 41 is joined to the ceiling beam 27 via the flange 63, and the lower part of the wooden pillar 41 is joined to the base 31 via the joint metal fitting 50. This combined use makes it easier to erect the wooden pillar 41 between the ceiling beam 27 and base 31 that have already been installed.

[0068] (6) Since the wooden pillars 41, 46 are erected after the ceiling beam 27 is erected, the construction work for erecting the ceiling beam 27 is easy, and the construction work for erecting the wooden pillars 41, 46 is also easy.

[0069] (7) After the ceiling beam 27 is erected, the wooden pillars 41, 46 are erected, and then the wall panel 71 is erected in the area enclosed by the ceiling beam 27, the wooden pillars 41, 46 and the foundation 31, and the wall panel 71 is joined to the ceiling beam 27, the wooden pillars 41, 46 and the foundation 31. Therefore, the ease of construction for erecting the ceiling beam 27, the ease of construction for erecting the wooden pillars 41, 46, and the ease of construction for erecting the wall panel 71 is good.

[0070] (8) The first floor of the building’s framework 1 is made of steel, which makes the first floor highly earthquake-resistant and has a long lifespan. Therefore, the building’s framework 1 contributes to achieving goals such as “sustainable urban development” and the “SDGs (Sustainable Development Goals).”

[0071] (9) The wooden columns 41, 46 and walls 70, 80, 90 of the structure 1 are made of wood, and the second and third floors of the structure 1 are also made of wood. The carbon dioxide emissions from the production and processing of wood to its exhaust are less than the carbon dioxide emissions from the production and processing of steel to its exhaust. Therefore, the structure 1 not only contributes to the realization of a decarbonized society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, but also contributes to the achievement of the Sustainable Development Goals (SDGs).

[0072] <Second embodiment> 1. Framework In the first embodiment, the joint structure between the wooden pillar 46 and the base 31 is the same as the joint structure between the wooden pillar 41 and the base 31, and the joint structure between the wooden pillar 46 and the ceiling beam 27 is the same as the joint structure between the wooden pillar 41 and the ceiling beam 27. In contrast, in the second embodiment, the joint structure between the wooden pillar 46 and the base 31 is different from the joint structure between the wooden pillar 41 and the base 31, and the joint structure between the wooden pillar 46 and the ceiling beam 27 is different from the joint structure between the wooden pillar 41 and the ceiling beam 27.

[0073] The joint structure between the wooden pillar 46 and the base 31 will be described with reference to Fig. 10 and Fig. 11. Fig. 10 is a diagram showing the first floor of the skeleton 1 in the second embodiment. Fig. 11 is an exploded perspective view of the joint structure between the wooden pillar 46 and the base 31. Fig. 11 is an exploded perspective view of area XI shown in Fig. 10.

[0074] A joint fitting 150 is fixed onto the base 31 with bolts or screws, etc., and the wooden post 46 is fixed to the joint fitting 150 with connectors 155a and 155b.

[0075] The joint fitting 150 includes a base plate 151 and an insert bar 152. The base plate 151 and the insert bar 152 are made of metal, for example, steel. The base plate 151 is a plate-shaped base. The base plate 151 is thicker than the base plate 51 of the joint fitting 50 of the first embodiment, and the rigidity of the base plate 151 is higher than the rigidity of the base plate 51. The insert bar 152 is a circular rod-shaped tenon. The insert bar 152 may be tubular so as to have a hollow center, or may be solid so as not to have a hollow center. The insert bar 152 is provided upright in the center of the base plate 151. The insert bar 152 and the base plate 151 are integrated. The diameter of the insert bar 152 is larger than the thickness of the insert plate 52 of the joint fitting 50 of the first embodiment, the rigidity of the insert bar 152 is higher than the rigidity of the insert plate 52, and the bending resistance of the insert bar 152 is higher than the bending resistance of the insert plate 52. The insert bar 152 has a plurality of first through holes 153a and one second through hole 153b. The first through holes 153a are formed in the insert bar 152 so as to be perpendicular to the axial direction of the insert bar 152. The second through holes 153b are formed in the insert bar 152 so as to be perpendicular to the axial direction of the insert bar 152. A plurality of second through holes 153b may be formed in the insert bar 152. The penetration direction of the first through holes 153a is perpendicular to the penetration direction of the second through holes 153b. The first through holes 153a and the second through holes 153b are arranged alternately in the axial direction of the insert bar 152.

[0076] The base plate 151 is placed face down on the base 31 and fixed to the top of the base 31 by fasteners such as screws or bolts. The insert bar 152 stands upright against the upper surface of the base 31.

[0077] On the other hand, in the wooden post 46, a mortise hole 47 is drilled from the lower end of the wooden post 46 to the interior of the wooden post 46 in the axial direction of the wooden post 46, and the mortise hole 47 opens at the lower end of the wooden post 46. A plurality of first insertion holes 48a penetrate from the side of the wooden post 46, passing over the mortise hole 47, to the opposite side, and the first insertion hole 48a is perpendicular to the axial direction of the wooden post 46. A single second insertion hole 48b penetrates from the other side of the wooden post 46, passing over the mortise hole 47, to the opposite side, and the second insertion hole 48b is perpendicular to the axial direction of the wooden post 46. A plurality of second insertion holes 48b may be formed in the wooden post 46. The penetration direction of the first insertion hole 48a is perpendicular to the penetration direction of the second insertion hole 48b. The first insertion holes 48a and the second insertion holes 48b are alternately arranged in the axial direction of the wooden post 46.

[0078] The lower end of the wooden post 46 faces the base plate 151 on the foundation 31, and the insert bar 152 is inserted into the mortise hole 47. The first through hole 153a of the insert bar 152 is coaxial with the first insertion hole 48a, and the second through hole 153b of the insert bar 152 is coaxial with the second insertion hole 48b. Connectors 155a and 155b are driven into the wooden post 46 from the side of the wooden post 46 and penetrate the insert bar 152. Specifically, the first connector 155a is inserted and fitted into the first insertion hole 48a of the wooden post 46 and the first through hole 153a of the insert bar 152, and the second connector 155b is inserted and fitted into the second insertion hole 48b of the wooden post 46 and the second through hole 153b of the insert bar 152. The connectors 155a and 155a contribute to fastening the wooden post 46 to the insert bar 152. The connectors 155a and 155b may be, for example, threaded bolts, dowels, dowel screws, pins, or drift pins. The entire first connector 155a may fit into the first insertion hole 48a and the first through-hole 153a, and the first connector 155a may not protrude from the first insertion hole 48a. The entire second connector 155b may fit into the second insertion hole 48b and the second through-hole 153b, and the second connector 155b may not protrude from the second insertion hole 48b.

[0079] The joint structure between the wooden pillar 46 and the ceiling beam 27 will be described with reference to Figures 10 and 12. Figure 12 is an exploded perspective view of the joint structure between the wooden pillar 46 and the ceiling beam 27. Figure 12 is an exploded perspective view of area XII shown in Figure 10.

[0080] An insert plate 163 made of a steel plate is fixed to the underside of the ceiling beam 27 by welding or the like, in an attitude perpendicular to the axial direction of the ceiling beam 27. The insert plate 163 hangs down from the underside of the ceiling beam 27. The thickness of the insert plate 163 is greater than the thickness of the flange 63 of the first embodiment, the rigidity of the insert plate 163 is higher than the rigidity of the flange 63, and the bending resistance of the insert plate 163 is higher than the bending resistance of the flange 63. The insert plate 163 has a plurality of through holes 164 that pass through the insert plate 163.

[0081] On the other hand, in the wooden post 46, slits 147 are cut into the wooden post 46 from the upper end and opposite side surfaces, and the slits 147 open at the upper end and two opposite side surfaces of the wooden post 46. A plurality of insertion holes 148 penetrate from the other side surface of the wooden post 46, past the slits 147, to the opposite side surface, in a direction parallel to the two opposite side surfaces. The upper end of the wooden post 46 faces the underside of the ceiling beam 27, and an insert plate 163 is inserted into the slits 147. The through hole 164 of the insert plate 163 is coaxial with the insertion hole 148. A connector 165 is driven into the wooden post 46 from the side surface of the wooden post 46 and penetrates the insert plate 163. Specifically, the connector 165 is inserted and fitted into the insertion hole 148 of the wooden post 46 and the through hole 164 of the insert plate 163. The connector 165 contributes to fastening the wooden post 46 to the insert plate 163. The connector 165 is made of metal, for example, steel. The connector 165 may also be made of wood. The connector 165 is, for example, a drift pin, a threaded bolt, a dowel, a dowel screw, or a pin. The entire connector 165 fits into the insertion hole 148 and the through hole 164, and the connector 165 does not have to protrude from the insertion hole 148.

[0082] Except for the points mentioned above, the skeleton 1 of the second embodiment is similar to the skeleton 1 of the first embodiment.

[0083] 2. Construction method of the structure The construction method of the body 1 will be explained.

[0084] (1) Steps (1), (2) and (3) in the first embodiment are carried out.

[0085] (2) Installation of joint fittings 13, similar to step (4) in the first embodiment, the joint fittings 50, 150 are fixed onto the base 31. For the joint fitting 150, the base plate 151 is placed face down on the base 31, and the insert bar 152 is placed upright against the upper surface of the base 31, and the base plate 151 is fixed to the base 31.

[0086] (3) Joint between wooden pillars and ceiling beams The insert plate 163 is welded to the underside of the ceiling beam 27 so that the insert plate 163 is perpendicular to the axial direction of the ceiling beam 27 and hangs down from the underside of the ceiling beam 27. Note that the insert plate 163 may be welded to the ceiling beam 27 in advance in a factory or the like before the ceiling beam 27 is transported to the construction site.

[0087] Before erecting the ceiling beam 27, the insert plate 163 is inserted into the slit 147 of the wooden column 46 at the construction site or factory. By inserting the connector 165 into the insertion hole 148 of the wooden column 46 and the through hole 164 of the insert plate 163, the wooden column 46 is joined to the ceiling beam 27 via the insert plate 163 between the wooden column 46 and the ceiling beam 27.

[0088] (4) Erection of ceiling beams Next, as shown in Figure 14, the ceiling beam 27 to which the wooden pillars 46 are joined is lifted up by a crane or the like. The lifted ceiling beam 27 is placed between the steel pillars 21 and 23. At this time, the insert bar 152 is inserted into the mortise hole 47 of the wooden pillars 46. Both ends of the ceiling beam 27 are fixed to the steel columns 21 and 23, respectively, and the ceiling beam 27 is erected horizontally between the steel columns 21 and 23.

[0089] (5) Joining wooden pillars Next, the connector 155a is inserted into the insertion hole 48a of the wooden post 46 and the through-hole 153a of the insert bar 152, and the connector 155b is inserted into the insertion hole 48b of the wooden post 46 and the through-hole 153a of the insert bar 152. This joins the wooden post 46 to the base 31 via the joint fitting 150.

[0090] (6) Installing the angle As shown in FIG. 15, the step (6) in the first embodiment is carried out.

[0091] (7) Installing wooden pillars Next, as shown in FIG. 16, the wooden pillars 41 are erected in the same manner as in step (7) in the first embodiment.

[0092] (8) Wall installation Next, similarly to step (8) in the first embodiment, the walls 70, 80, and 90 are installed (see FIG. 10).

[0093] 3. Modifications of the construction method of the structure In the above construction method, wooden columns 46 are joined to ceiling beams 27 before erecting the ceiling beams 27, and then the ceiling beams 27 are erected, and then the wooden columns 46 are joined to the foundation 31. Alternatively, as shown in Figure 17, wooden columns 46 may be joined to the foundation 31 with connectors 155a, 155b and insert bars 152 before erecting the ceiling beams 27. After joining wooden columns 46 to the foundation 31, the ceiling beams 27 are erected between steel columns 21, 23, and then the wooden columns 46 are joined to the ceiling beams 27 with insert plates 163 and connectors 165.

[0094] 4. Technically advantageous effects (1) Because the wooden pillars 41 are erected after the ceiling beams 27 are erected, the construction of the ceiling beams 27 is easy, and the construction of the wooden pillars 41 is also easy. Furthermore, because the upper part of the wooden pillar 41 is joined to the ceiling beams 27 via the flanges 63 and the lower part of the wooden pillar 41 is joined to the base 31 via the joint fittings 50, the construction of the wooden pillars 41 is easy, and even if there is an error in the length of the wooden pillars 41 due to the distance between the ceiling beams 27 and the base 31, the error does not pose a problem.

[0095] (2) As shown in Figure 14, the wooden pillars 46 are joined to the ceiling beams 27 before the ceiling beams 27 are erected. Alternatively, as shown in Figure 17, the wooden pillars 46 are erected on the foundation 31 before the ceiling beams 27 are erected. These contribute to improving the pull-out strength of the wooden pillars 46. In other words, even if a large external force such as a strong wind or an earthquake is applied to the wooden pillars 41, 46 and the walls 70, 80, 90, the wooden pillars 46 are unlikely to come off, and the wooden pillars 41, 46 and the walls 70, 80, 90 can withstand the external force.

[0096] (3) The insert bar 152 of the joint fitting 150 is pillar-shaped, and the insert bar 152 is inserted into the hollow pillar-shaped mortise hole 47, and the connectors 155a and 155b are driven into the wooden post 46 and the insert bar 152 from different directions, respectively, so that the joining strength between the wooden post 46 and the base 31 is high.

[0097] (4) It is possible to achieve both the ease of construction of the wooden pillars 41 and the high bearing strength of the wooden pillars 46. Because the wall panels 71 are joined to the wooden pillars 46, which have high pull-out strength, and the wall panels 71 are joined to the wooden pillars 41, which are easy to construct, it is possible to achieve both the ease of construction of the wall in the area enclosed by the ceiling beams 27, horizontal members 31, and wooden pillars 41, 46, and the high durability and strength of the wall.
