In other words, even if the length of the first wooden post (41) has an error in relation to the distance between the ceiling beam (27) and the horizontal member (31), the first insert plate (52), the first slit (42), and the flange (63) contribute to ensuring that the first wooden post (41) can be erected and temporarily fastened between the ceiling beam (27) and the horizontal member (31). The first wooden post (41) temporarily fastened between the ceiling beam (27) and the horizontal member (31) is joined to the flange (63), thereby permanently fastening the first wooden post (41) to the ceiling beam (27). The first connector (55) is driven into the first wooden post (41) through the first insert plate (52), thereby permanently fastening the first wooden post (41) to the horizontal member (31). Therefore, the flange 63, the first insert plate 52, the first slit 42, and the first connector 55 contribute to erecting the first wooden pillar 41 under the previously erected ceiling beam 27. Since the first wooden pillar 41 is erected after the ceiling beam 27 is erected, the workability of erecting the ceiling beam 27 is good, and the workability of erecting the first wooden pillar 41 is also good. Meanwhile, the insert bar (152) is erected against the upper surface of the horizontal member (31), the mortise hole (47) is drilled from the lower end of the second wooden post (46) in the axial direction of the second wooden post (46), the insert bar (152) is inserted into the mortise hole (47), and the second connector (155a or 155b) penetrates the insert bar (152) and is driven into the second wooden post (46), so that the second wooden post (46) is firmly joined to the horizontal member (31), and the pull-out strength of the second wooden post (46) is high. In addition, the second slit (147) is cut out from the upper end of the second wooden pillar (46) in the axial direction of the second wooden pillar (46), the second insert plate (163) hangs down from the ceiling beam (27), the second insert plate (163) is inserted into the second slit (147), and the third connector (165) penetrates the second insert plate (163) and is driven into the second wooden pillar (46), so that the second wooden pillar (46) is firmly joined to the horizontal member (31), and the pull-out strength of the second wooden pillar (46) is high. The wall panel (71) is joined to the second wooden pillar (46) which has high pull-out strength, and the wall panel (71) is joined to the first wooden pillar (41) which is easy to construct, so that it is possible to achieve both good construction efficiency in constructing a wall in the area enclosed by the ceiling beam (27), the horizontal member (31), the first wooden pillar (41), and the second wooden pillar (46) and high durability and strength of the wall.

In other words, even if there is an error in the length of the first wooden pillar (41) from the distance between the ceiling beam (27) and the horizontal member (31), the flange (63) contributes to ensuring that the first wooden pillar (41) can be erected and temporarily fastened between the ceiling beam (27) and the horizontal member (31). The first wooden pillar (41), which is temporarily fastened between the ceiling beam (27) and the horizontal member (31), is joined to the flange (63), whereby the first wooden pillar (41) is permanently fastened to the ceiling beam (27). Therefore, the flange (63) contributes to erecting the first wooden pillar (41) below the ceiling beam (27) that has been erected previously. Since the first wooden pillar (41) is erected after the ceiling beam (27) has been erected, not only is the erection of the ceiling beam (27) easy, but so is the erection of the first wooden pillar (41) easy.

A body characterized by the above is provided.

[0011] According to the invention of claim 3 as described above, the flange (63) is joined to the underside of the ceiling beam (27) and hangs down from the ceiling beam (27), so that when the first wooden pillar (41) is placed between the previously erected ceiling beam (27) and the horizontal member (31), the first wooden pillar (41) can be tilted with respect to the vertical direction and then brought into vertical position so that the first wooden pillar (41) abuts against the flange (63). In other words, even if there is an error in the length of the first wooden pillar (41) from the distance between the ceiling beam (27) and the horizontal member (31), the flange (63) contributes to ensuring that the first wooden pillar (41) can be erected and temporarily fastened between the ceiling beam (27) and the horizontal member (31). The first wooden pillar (41), which is temporarily fastened between the ceiling beam (27) and the horizontal member (31), is joined to the flange (63), whereby the first wooden pillar (41) is permanently fastened to the ceiling beam (27). Therefore, the flange (63) contributes to erecting the first wooden pillar (41) below the ceiling beam (27) that has been erected previously. Since the first wooden pillar (41) is erected after the ceiling beam (27) has been erected, not only is the erection of the ceiling beam (27) easy, but so is the erection of the first wooden pillar (41) easy.

The floor beam 25 rests on the foundation 10 and is fixed to the foundation 10.

[0026] The ceiling beams 27 are made of H-shaped steel. The ceiling beams 27 are arranged horizontally above the floor beams 25. Both ends of the floor beams 25 are fixed to the steel columns 21 and 23, respectively, and the floor beams 25 are installed horizontally between the steel columns 21 and 23.

[0027] In addition to the steel columns 21, 23, floor beams 25, and ceiling beams 27 shown in Figure 1, the frame 1 also includes steel columns, floor beams, and ceiling beams on the first floor, and a rigid frame structure is constructed by assembling these steel columns, floor beams, and ceiling beams using the steel frame construction method. The steel columns 21, 23, floor beams 25, and ceiling beams 27 are part of this rigid frame structure. Floor sub-beams may be erected between the floor beams. Ceiling sub-beams may be erected between the ceiling beams. A sub-beam is a beam that is erected between main beams and transfers the floor load to the main beams. A main beam is a beam that is erected between columns. The floor beams 25 and ceiling beams 27 are main beams.

[0028] The base 31 is a wooden timber. The base 31 is made of solid wood or laminated wood. The base 31 rests on the floor beams 25 and is fixed to the floor beams 25 with fasteners. The base 31 is a horizontal member installed horizontally along the floor beams 25. Both ends of the base 31 may be fixed to the steel columns 21, 23, respectively, or may not be fixed to the steel columns 21, 23. Note that the base 31 may rest on the foundation 10 and be fixed to the foundation 10 without installing the floor beams 25.

[0029] The wooden pillars 41, 46 are wooden timbers. The wooden pillars 41, 46 are made of solid wood or laminated wood. The wooden pillars 41, 46 are installed upright on the base 31 between the steel pillars 21, 23. The steel pillar 21, wooden pillar 41, wooden pillar 46, and steel pillar 23 are arranged in this order with a gap between them.

[0030] A wooden pillar 41 is fixed to a base 31. The joint structure between the wooden pillar 41 and the base 31 will be described with reference to Figures 1 and 2. Figure 2 is an exploded perspective view of the joint structure between the wooden pillar 41 and the base 31. Figure 2 is an exploded perspective view of area II shown in Figure 1. As shown in Figures 1 and 2, a joint fitting 50 is fixed onto the base 31 with bolts or screws, etc., and the wooden pillar 41 is fixed to the joint fitting 50 with a connector 55.

[0031] The joint fitting 50 has a base plate 51 and an insert plate 52. The insert plate 52 is disposed approximately perpendicular to the base plate 51, and the insert plate 52 and the base plate 51 are integrated. The base plate 51 is placed face down on the base 31 and fixed to the top of the base 31 with fasteners such as screws or bolts.

A plurality of insertion holes 43 penetrate from another side surface of the wooden pillar 41, past the slit 42, to the opposite side surface in a direction parallel to the two opposing side surfaces. The fact that the slit 42 opens at the side surface of the wooden pillar 41 contributes to the ability to insert the insert plate 52 into the slit 42 while moving the wooden pillar 41 laterally.

[0033] The lower end of the wooden post 41 faces the base plate 51 on the foundation 31, and the insert plate 52 is inserted into the slit 42. The through hole 53 of the insert plate 52 is coaxial with the insertion hole 43. A connector 55 is driven into the wooden post 41 and penetrates the insert plate 52. Specifically, the connector 55 is inserted and fitted into the insertion hole 43 of the wooden post 41 and the through hole 53 of the insert plate 52. The connector 55 contributes to fastening the wooden post 41 to the insert plate 52. The connector 55 is made of metal, for example, steel. The connector 55 may also be made of wood. The connector 55 is, for example, a threaded bolt, a dowel, a dowel screw, a pin, or a drift pin.

The connectors 155a and 155a contribute to fastening the wooden post 46 to the insert bar 152. The connectors 155a and 155b are, for example, threaded bolts, dowels, dowel screws, pins, or drift pins. The entire connector 155a may fit into the insertion hole 48a and the through-hole 153a, and the connector 155a may not protrude from the insertion hole 48a.

[0043] As shown in Fig. 1, a wooden pillar 46 is fixed to a ceiling beam 27. The joint structure between the wooden pillar 46 and the ceiling beam 27 will be described with reference to Figs. 1 and 6. Fig. 6 is an exploded perspective view of the joint structure between the wooden pillar 46 and the ceiling beam 27. Fig. 6 is an exploded perspective view of area VI shown in Fig. 1. As shown in Figs. 1 and 5, a joint fitting 150 is fixed onto the base 31 with bolts or screws, etc., and the wooden pillar 46 is fixed to the joint fitting 150 with connectors 155a and 155b.

[0044] 1 and 6, 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 orientation perpendicular to the axial direction of the ceiling beam 27. The insert plate 163 hangs down from the underside of the ceiling beam 27.

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.

The upper part of wall 70 is abutted against flange 63, and the upper part of wall 70 is fixed to flange 63 with screws or the like. The lower part of wall 70 is joined to base 31.

[0047] The wall 70 is made of wood and has a wooden wall panel 71 and wooden side members 72, 73. The wall panel 71 has a rectangular frame formed by assembling a pair of upper and lower wooden horizontal frames and a pair of left and right wooden vertical frames into a rectangular frame shape, and wooden face materials attached to the front and rear surfaces of the frame. If necessary, the wall panel 71 may have one or more wooden crosspieces attached to the rectangular frame on the inside. When the wall panel 71 forms an exterior wall, the wall panel 71 may have an insulating material such as glass wool, rock wool, or foamed resin filled between the face materials. The side members 72 and 73 are square timbers. The side member 72 is joined to the side surface of the wall panel 71 with adhesive or screws, and the side member 72 is joined to the side surface of the wall panel 71 with adhesive or screws. Meanwhile, the side material 44 is joined to the side surface of the wooden post 41 with adhesive or screws, etc. The side material 44 and the side material 72 are overlapped in the wall thickness direction (width direction of the beams 25, 27), and these side materials 44, 72 are joined to each other with adhesive or screws, etc. In this way, one side of the wall 70 is joined to the wooden post 41. The side materials 44, 72 fit between the wooden post 41 and the wall panel 71.

The top of the wall 90 is abutted against the flange 63, and the top of the wall 90 is fixed to the flange 63 with screws or the like. The bottom of the wall 90 is joined to the foundation 31.

[0050] 2. Construction method of the structure The construction method of the body 1 will be explained.

[0051] (1) Erecting steel columns and constructing foundations and footings First, the steel columns 21, 23 are erected, and the rebar for the footings 11, 13 is arranged around the bottom ends of the steel columns 21, 23, and the rebar for the foundation 10 is also arranged. Steel columns other than the steel columns 21, 23 shown in Figure 1 are also erected, and the rebar for the footings is arranged around the bottom ends of these steel columns. Furthermore, formwork is also assembled. Next, concrete is poured inside the formwork, and after the concrete has cured, the formwork is dismantled. In this way, the foundation 10, footings 11, 13, and other footings (these other footings support steel columns other than the steel columns 21, 23) are constructed.

[0052] (2) Erection of floor beams Next, floor beam 25 is lifted up by a crane or the like, and placed on foundation 10. 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.

[0053] (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.

[0054] (4) Installation of joint fittings Next, as shown in Fig. 9, the joint fittings 50, 150 are fixed onto the base 31. Specifically, the base plates 51, 151 of the joint fittings 50, 150 are placed face down on the base 31, and the insert plates 52 and insert bars 152 of the joint fittings 50, 150 are placed upright against the upper surface of the base 31, and the base plates 51, 151 are fixed to the base 31. The joint fittings 50, 150 may be attached to the base 31 at any time before erecting the wooden posts 41, 46 described below.

[0055] (5) 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.

[0056] 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.

[0057] (6) Erection of ceiling beams 10, the ceiling beam 27 is lifted up by a crane or the like and placed between the steel frame columns 21 and 23. At this time, the insert bar 152 is inserted into the mortise hole 47 of the wooden column 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. Similarly, the other ceiling beams are erected between the steel columns. Small ceiling beams may be erected between the ceiling beams. The ceiling beam 27 may also be erected before the foundation 31 is installed.

[0058] (7) 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.

[0059] (8) Installing the angle Next, as shown in Figure 11, 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. 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.

[0060] (9) Installing wooden pillars Next, wooden pillars 41 are erected between the base 31 and the ceiling beams 27.

[0061] 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.

[0062] 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 fixed 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 fixed to the flange 63 with fasteners 65 such as screws.

[0063] (10) 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.

[0064] 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).

[0065] 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.

[0066] 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 them, and then ceiling beams 27 are erected, and then wooden columns 46 are joined to foundation 31. Alternatively, as shown in Figure 13, wooden columns 46 may be joined to foundation 31 with connectors 155a, 155b and insert bars 152 before erecting ceiling beams 27. After joining wooden columns 46 to foundation 31, ceiling beams 27 are erected between steel columns 21, 23, and then wooden columns 46 are joined to ceiling beams 27 with insert plates 163 and connectors 165.

[0067] 4. Technically advantageous effects (1) Even if the upper end of the wooden pillar 41 does not stably abut the underside of the ceiling beam 27 due to an error in the length of the wooden pillar 41 from the distance between the ceiling beam 27 and the foundation 31, the flange 63 is joined to the underside of the ceiling beam 27, the flange 63 hangs down from the ceiling beam 27, and the side of the wooden pillar 41 abuts against and is joined to the flange 63, so the wooden pillar 41 is securely fixed to the previously erected ceiling beam 27. Therefore, the skeleton 1 and its construction method are suitable for later erecting the wooden pillar 41 under a previously erected ceiling beam 27. The joint structure and manufacturing method between the wooden pillar 41 and the ceiling beam 27 are also suitable for later erecting the wooden pillar 41 under a previously erected ceiling beam 27.

[0068] (2) Because the ceiling beams 27 are erected before the wooden columns 41 are erected, in order for the wooden columns 41 to be reliably positioned between the ceiling beams 27 and the foundation 31 after the ceiling beams 27 are erected, the length of the wooden columns 41 needs to be slightly shorter than the distance between the ceiling beams 27 and the foundation 31. Even in this case, the flanges 63 hang down from the ceiling beams 27, and the sides of the wooden columns 41 abut against and are joined to the flanges 63, so the wooden columns 41 are fixed to the ceiling beams 27 that were erected earlier. In other words, even if the upper ends of the wooden columns 41 are slightly separated from the undersides of the ceiling beams 27, the flanges 63 contribute to fixing the wooden columns 41, 46 to the ceiling beams 27.

[0069] (3) When attaching the angle 60 to the ceiling beam 27, the web 61 of the angle 60 is in surface contact with the underside of the ceiling beam 27 and 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 column 41. Therefore, when the wooden column 41 is later erected under the ceiling beam 27 that has been previously erected, the upper part of the wooden column 41 is stably fixed to the ceiling beam 27.

[0070] (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.

[0071] (5) The upper part of the wooden pillar 41 is fixed to the ceiling beam 27 via the flange 63, and the lower part of the wooden pillar 41 is fixed 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.

[0072] (6) Since the wooden pillars 41 are erected after the ceiling beams 27 are erected, the construction work for erecting the ceiling beams 27 is easy, and the construction work for erecting the wooden pillars 41 is also easy.

[0073] (7) As shown in Figure 10, the wooden pillars 46 are joined to the ceiling beams 27 before the ceiling beams 27 are erected. Alternatively, as shown in Figure 13, 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. 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.

[0074] (8) 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.

[0075] (9) 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.

[0076] (10) After the ceiling beams 27 are erected, the wooden pillars 41 are set up, and then the wall panels 71 are set up in the area enclosed by the ceiling beams 27, the wooden pillars 41 and the foundation 31, and the wall panels 71 are joined to the ceiling beams 27, the wooden pillars 41, 46 and the foundation 31. Therefore, the ease of construction for erecting the ceiling beams 27, the ease of construction for erecting the wooden pillars 41, and the ease of construction for erecting the wall panels 71 is good.

[0077] (11) 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).”

[0078] (12) 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 exhaust are less than the carbon dioxide emissions from the production and processing of steel to 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 SDGs.

[0079] <Second embodiment> In the first embodiment, the joint structure between the wooden pillar 41 and the base 31 is different from the joint structure between the wooden pillar 46 and the base 31, and the joint structure between the wooden pillar 41 and the ceiling beam 27 is different from the joint structure between the wooden pillar 46 and the ceiling beam 27. In contrast, as shown in Fig. 14, the joint structure between the wooden pillar 41 and the base 31 may be the same as the joint structure between the wooden pillar 46 and the base 31, and the joint structure between the wooden pillar 41 and the ceiling beam 27 may be the same as the joint structure between the wooden pillar 46 and the ceiling beam 27.

[0080] Since both wooden pillars 41, 46 have high pull-out strength, even if a large external force such as a strong wind or an earthquake is applied to the wooden pillars 41, 46 and walls 70, 80, 90, the wooden pillars 46 are unlikely to come off, and the wooden pillars 41, 46 and walls 70, 80, 90 can withstand the external force.

[0081] In the construction method of the skeleton 1 of the second embodiment, the wooden pillars 41 may be joined to the ceiling beams 27 before erecting the ceiling beams 27 as shown in Fig. 15, or the wooden pillars 41 may be joined to the base 31 before erecting the ceiling beams 27 as shown in Fig. 17. Also, as shown in Fig. 16, the wooden pillars 46 may be joined to the ceiling beams 27 and the wooden pillars 41 may be joined to the base 31 before erecting the ceiling beams 27, and then the ceiling lining 27 may be erected.
