Description

[Technical Field]

[0001] The present invention relates to a joining structure and a joining method. [Background technology]

[0002] For the purpose of seismic reinforcement of structures composed of structural members such as columns and beams formed from H-shaped steel or the like, reinforcing members such as knee braces and braces are joined to the structural members. Joining of reinforcing members to structural members is generally performed by welding. However, in factories and the like that are already in operation, restrictions on the use of fire make it difficult to adopt joining methods that use welding. From this perspective, for example, Patent Document 1 proposes a joining method that does not use welding. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-32689 Summary of the Invention [Problem to be solved by the invention]

[0004] In the joining method disclosed in Patent Document 1, the fixing surface of a gusset plate attached to a knee brace, which is a reinforcing member, is fixed to the flange of an H-shaped steel component, which is a structural member, by clamping. The fixing surface of the gusset plate and the flange of the H-shaped steel are in contact with each other and clamped by the clamping fixture, so that the clamping force of the clamping fixture resists tensile forces acting perpendicular to the longitudinal direction of the H-shaped steel, and the frictional force between the fixing surface of the gusset plate and the flange of the H-shaped steel resists shear forces acting in the longitudinal direction of the H-shaped steel. However, the frictional force between the fixing surface of the gusset plate and the flange of the H-shaped steel is insufficient to resist shear forces. In particular, the fixing surface is also subjected to tensile forces acting perpendicular to the longitudinal direction of the H-shaped steel, and the frictional force reduces the fixing surface's ability to sufficiently resist shear forces.

[0005] The present invention has been made in consideration of the above problems, and aims to provide a joining structure and joining method that can improve resistance to shear forces that occur between a constituent member and a reinforcing member. [Means for solving the problem]

[0006] The joining structure of the present invention is a joining structure for joining a reinforcing member to a constituent member that constitutes a structure, and comprises an end member provided at an end of the reinforcing member and joined to the constituent member, a tensile force resisting member joined to the constituent member and resisting the tensile force received from the reinforcing member, a fixing portion arranged outside the constituent member and fixing the end member and the tensile force resisting member to each other directly or indirectly, and a shear force resisting member joined to the constituent member, characterized in that the shear force resisting member is arranged so as to abut directly or indirectly against the end member in the longitudinal direction of the constituent member.

[0007] The joining method of the present invention is a method for joining a reinforcing member to a constituent member that constitutes a structure, and includes the steps of joining an end member provided at an end of the reinforcing member to the constituent member, joining a tensile force resisting member that resists the tensile force received from the reinforcing member to the constituent member, fixing the end member and the tensile force resisting member directly or indirectly to each other using a fixing portion arranged on the outside of the constituent member, and joining a shear force resisting member to the constituent member, wherein the shear force resisting member is arranged so as to abut directly or indirectly against the end member in the longitudinal direction of the constituent member. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a joining structure and joining method that can improve resistance to shear forces that occur between a structural member and a reinforcing member. [Brief explanation of the drawings]

[0010] Hereinafter, a joining structure and a joining method according to an embodiment of the present invention will be described with reference to the accompanying drawings. However, the embodiment shown below is merely an example, and the joining structure and joining method of the present invention are not limited to the following example.

[0011] As shown in FIG. 1 , the joining structure 1 and joining method of this embodiment are used to join a reinforcing member KB to structural members SB and SP, such as beams SB and columns SP, that constitute a structure S. The structure S to which the joining structure 1 is applied is not particularly limited, and examples include factory buildings, warehouses, and buildings. As will be understood from the following explanation, the joining structure 1 and joining method do not require welding to the structure, and therefore can be suitably applied to not only newly constructed structures but also existing structures in particular. The structural members SB and SP to which the reinforcing member KB is joined are made of steel materials such as H-shaped steel or square steel pipes. The joining structure 1 and joining method can be used, for example, to join a reinforcing member KB to a structural member (beam) SB, which is an H-shaped steel, as shown in FIGS. 2 and 4 , or to join a reinforcing member KB to a structural member (column) SP, which is a square steel pipe, as shown in FIGS. 7 to 12 .

[0012] The reinforcing members KB, which are joined to the structural members SB and SP, reinforce the structure S by being joined to the structural members SB and SP. The reinforcing members KB absorb the vibration energy generated in the structural members SB and SP when the structure S is subjected to external disturbances such as earthquake motion or wind, and / or resist the external forces received from the structural members SB and SP, thereby suppressing deformation of the structure S and improving its strength, thereby improving the seismic resistance and vibration control of the structure S. The reinforcing members KB are not particularly limited as long as they can be joined to the structural members SB and SP to reinforce the structure S. For example, knee braces as shown in Figure 1, other known reinforcing members such as braces, and reinforcing members with frame structures newly installed within an existing steel frame can be used. For example, H-shaped steel or flat steel can be used as the reinforcing members KB. When H-shaped steel and flat steel are used as the reinforcing member KB, deformation of the end member 2 can be suppressed by providing a rib KB1 (see Figures 2 to 8; in the illustrated example, a rib KB1 is provided on the H-shaped steel, but a rib can also be provided on the flat steel) that connects the H-shaped steel and flat steel to the end member 2 described below.

[0013] As shown in FIG. 1, the reinforcing member KB is formed as a long member extending along the longitudinal direction LD and is bridged between the beams SB and columns SP, which are components of the structure S. As a result, the reinforcing member KB is joined to the beams SB or columns SP so that the longitudinal direction LD of the reinforcing member KB is inclined from a direction (second direction D2) perpendicular to the longitudinal direction (hereinafter also referred to as the first direction) D1, which is the direction in which the beams SB or columns SP extend. The second direction D2 is a direction perpendicular to the first direction D1 in a plane (within the plane of the paper in the figure) that includes the longitudinal direction LD of the reinforcing member KB and the first direction D1 of the beams SB or columns SP. For example, when a compressive force (pressure) or tensile force acts on the beams SB or columns SP along the longitudinal direction LD from the reinforcing member KB, a compressive force (pressure) or tensile force along the second direction D2 and a shear force along the first direction D1 are generated between the reinforcing member KB and the beams SB or columns SP. As will be described in detail below, the joint structure 1 of this embodiment can transmit the shear force in the first direction D1 and the compressive and tensile forces in the second direction D2 that occur between the reinforcing member KB and the constituent members SB, SP between the reinforcing member KB and the constituent members SB, SP without attenuation or in a manner that suppresses attenuation. Note that the reinforcing member KB may be bridged, for example, between adjacent beams SB or adjacent columns SP, and joined to the beams SB or columns SP so that the longitudinal direction LD of the reinforcing member KB is approximately perpendicular to the first direction D1 of the beams SB or columns SP.

[0014] As shown in Figures 2 and 4, and Figures 7 to 12, the joint structure 1 is provided at the end of the reinforcing member KB and comprises an end member 2 joined to the constituent members SB and SP, a tensile force resistance member 3 joined to the constituent members SB and SP, a fixing part 4 that directly or indirectly fixes the end member 2 and the tensile force resistance member 3 to each other, and a shear force resistance member 5 joined to the constituent members SB and SP.

[0015] As shown in Figures 2 and 4, as well as Figures 7 to 12, the end member 2 is provided at the end of the reinforcing member KB in the longitudinal direction LD and is joined to the components SB and SP by being directly or indirectly fixed to the tensile resistance member 3, which is joined to the components SB and SP. Here, the state in which the end member 2 is directly or indirectly fixed to the tensile resistance member 3 includes a state in which relative movement between the end member 2 and the tensile resistance member 3 is restricted in all directions, but it is sufficient to include a state in which relative movement of the end member 2 with respect to the tensile resistance member 3 is restricted at least in the direction away from the components SB and SP in the second direction D2, and does not necessarily include only a state in which relative movement between the end member 2 and the tensile resistance member 3 is restricted in all directions. In the examples shown in Figures 2 and 4, as well as Figures 7 and 8, the end member 2 is joined to the components SB and SP by being directly fixed to the tensile resistance member 3. 9 and 10, the end member 2 is joined to the component SP by being indirectly fixed to the tensile force resistance member 3 via a portion of the reinforcing member KB other than the end member 2. In the example shown in FIGS. 11 and 12, the end member 2 is joined to the component SP by being indirectly fixed to the tensile force resistance member 3 via a joining member 8, which will be described later. The end member 2 is joined to the components SB and SP, thereby joining the reinforcing member KB to the components SB and SP. In this embodiment, the end member 2 is formed integrally with the reinforcing member KB, but it may also be formed as a separate member from the reinforcing member KB and connected to the end of the reinforcing member KB via a fixing means such as a bolt.

[0016] As shown in Figures 2, 7, 9, and 11, the end member 2 is arranged so as to directly or indirectly abut against the components SB, SP along the second direction D2. By arranging the end member 2 so as to directly or indirectly abut against the components SB, SP along the second direction D2, relative movement of the end member 2 in a direction approaching the components SB, SP is suppressed in the second direction D2. As a result, when a compressive force in the second direction D2 is generated between the reinforcing member KB and the components SB, SP, the end member 2 is suppressed from moving relative to the components SB, SP in a direction approaching the components SB, SP, and can transmit the compressive force between the reinforcing member KB and the components SB, SP without attenuation or with attenuation suppressed.

[0017] In this embodiment, as shown in FIGS. 2, 4, and 7 to 12, the end member 2 is positioned so that it abuts against the shear force resistance member 5 in the second direction D2 and indirectly abuts against the components SB and SP via the shear force resistance member 5. As a result, when a compressive force in the second direction D2 occurs between the reinforcing member KB and the components SB and SP, the end member 2 presses the shear force resistance member 5 against the components SB and SP along the second direction D2. Pressing the shear force resistance member 5 against the components SB and SP along the second direction D2 increases the bonding strength (adhesion) between the components SB and SP and the shear force resistance member 5. This strengthens the bond between the shear force resistance member 5 and the components SB and SP, thereby further increasing the resistance to shear forces along the first direction D1, which will be described in detail below. However, the end member 2 may also be positioned so that it directly abuts against the components SB and SP without the shear force resistance member 5.

[0018] The end member 2 may be joined to the structural members SB and SP by directly or indirectly abutting against them, and the positions of the structural members SB and SP are not particularly limited. For example, as shown in Figures 2 and 4, if the structural member (beam) SB is an H-shaped steel beam having a pair of flanges SB1 and a web SB2 connecting the pair of flanges SB1 and SB1, the end member 2 is joined to the outer surface of one of the flanges SB1 of the H-shaped steel beam by directly or indirectly abutting against it. Also, as shown in Figures 7 to 12, if the structural member (column) SP is a square steel pipe having four side surfaces SP1 to SP4, with adjacent side surfaces generally perpendicular to each other, the end member 2 is joined to the first side surface SP1 of the square steel pipe by directly or indirectly abutting against it.

[0019] The end member 2 may be configured to directly or indirectly abut against the components SB and SP, and its structure is not particularly limited. In this embodiment, as shown in FIGS. 2, 4, and 7 to 12, the end member 2 is formed of a substantially flat steel plate having a substantially flat abutment surface 2a. The abutment surface 2a of the end member 2 abuts indirectly against the components SB and SP via the shear force resistance member 5 by making surface contact with the substantially flat surface of the shear force resistance member 5. As a result, when a compressive force in the second direction D2 occurs between the reinforcing member KB and the components SB and SP, the compressive force is dispersed within the abutment surface 2a, suppressing the generation of localized stress and preventing damage to not only the end member 2 and the shear force resistance member 5, but also the reinforcing member KB and the components SB and SP. The end member 2 may have a shape other than a substantially flat plate, as long as it has the abutment surface 2a that makes surface contact with at least the surfaces of the components SB and SP or the shear force resistance member 5. Furthermore, the end member 2 may have a surface shape that corresponds to the surface shape of the component members SB, SP or shear force resistance member 5. For example, as shown in FIG. 5, a recess 2b may be formed on the abutment surface 2a to correspond to the surface shape of the shear force resistance member 5 with which the end member 2 abuts.

[0020] 2 and 4, and 7 to 12, the end member 2 is fixed directly or indirectly in the second direction D2 to the tensile force resisting member 3 joined to the components SB, SP so that relative movement of the end member 2 in the second direction D2 away from the components SB, SP is restricted, and relative movement of the end member 2 in the second direction D2 away from the components SB, SP is restricted. As a result, when a tensile force in the second direction D2 occurs between the reinforcing member KB and the components SB, SP, the relative movement of the end member 2 in the second direction D2 away from the components SB, SP is restricted, and the tensile force can be transmitted between the reinforcing member KB and the components SB, SP via the tensile force resisting member 3 without attenuation or with attenuation restricted.

[0021] The end member 2 need only be configured to directly or indirectly abut the components SB and SP, and its size is not particularly limited. For example, in the example shown in FIGS. 4 and 8, the end member 2 is configured to protrude outward from both sides of the components SB and SP in a third direction D3, which is perpendicular to the first direction D1 and the second direction D2 of the components SB and SP. The end member 2 is fixed to the tensile force resistance member 3 by the fixing portions 4 at the portions protruding outward from the components SB and SP. However, as long as the end member 2 can be fixed directly or indirectly to the tensile force resistance member 3 by the fixing portions 4, it may have approximately the same size as the components SB and SP, or may be smaller than the components SB and SP, without protruding outward from the components SB and SP in the third direction D3. For example, in the example shown in FIGS. 10 and 12, the end member 2 has approximately the same size as or smaller than the components SP in the third direction D3.

[0022] As shown in Figures 2, 7, 9, and 11, the end member 2 is positioned so as to abut against the shear force resisting member 5 joined to the components SB, SP in the longitudinal direction (first direction) D1 of the components SB, SP. This restricts the end member 2 from moving relative to the shear force resisting member 5 in the first direction D1, and restricts its movement relative to the components SB, SP. Therefore, when a shear force occurs between the reinforcing member KB and the components SB, SP in the first direction D1, the end member 2 is restricted from moving relative to the components SB, SP in the first direction D1, and the shear force can be transmitted between the reinforcing member KB and the components SB, SP via the shear force resisting member 5 without or with limited attenuation. In the joining structure 1 and joining method of this embodiment, instead of resisting the shear force in the first direction D1 by the frictional force between the end member 2 and the constituent members SB, SP as in the conventional technology, the shear force in the first direction D1 is resisted by a shear force resistance member 5 separate from the end member 2 and the constituent members SB, SP, thereby improving the resistance to the shear force generated between the reinforcing member KB and the constituent members SB, SP compared to the conventional technology.

[0023] The end member 2 may be arranged to abut against the shear force resistance member 5 in the first direction D1, and the method of abutment is not particularly limited. For example, in the examples shown in Figures 2, 7, 9, and 11, the end member 2 is arranged relative to the shear force resistance member 5 so that both end portions 2c, 2c of the end member 2 in the first direction D1 directly abut against abutment portions 5a, 5a formed on the shear force resistance member 5 facing each other in the first direction D1. In addition, in the example shown in Figure 5, the end member 2 is arranged relative to the shear force resistance member 5 so that both wall portions in the first direction D1 of the recess 2b formed on the abutment surface 2a of the end member 2 directly abut against abutment portions 5a, 5a formed on both end portions in the first direction D1 of the protrusion provided on the shear force resistance member 5. By arranging the end member 2 so that it abuts the shear force resistance member 5 on both sides in the first direction D1, relative movement with respect to the shear force resistance member 5 in both directions in the first direction D1 is restricted, and relative movement with respect to the components SB and SP is restricted. However, it is sufficient that relative movement of the end member 2 in at least one direction in the first direction D1 is restricted, and it may be arranged so that it abuts the shear force resistance member 5 in only one direction in the first direction D1. Furthermore, it is sufficient that relative movement of the end member 2 along the first direction D1 is restricted, and it may be arranged so that it abuts the shear force resistance member 5 indirectly via another member.

[0024] The end member 2 is preferably positioned relative to the shear force resisting member 5 so that the tensile force in the second direction D2 generated between the reinforcing member KB and the structural members SB and SP does not directly act on the shear force resisting member 5, or even if it does, the action is suppressed. For this purpose, in this embodiment, the end member 2 is positioned relative to the shear force resisting member 5 so that relative movement in the second direction D2 away from the shear force resisting member 5 is permitted only in relation to the shear force resisting member 5 (in practice, the end member 2 is fixed directly or indirectly to the tensile force resisting member 3, so that relative movement with respect to the shear force resisting member 5 is suppressed). More specifically, the end member 2 is not fixed to the shear force resisting member 5 via fixing means such as adhesive or bolts. In this way, the shear force resisting member 5 is not subjected to tensile force in the second direction D2 via the end member 2, or even if it is subjected to tensile force, the tensile force is suppressed, thereby suppressing a decrease in the joining strength (adhesion strength) of the shear force resisting member 5 to the constituent members SB, SP, and suppressing a decrease in the resistance to shear force by the shear force resisting member 5. As a result, the joining structure 1 and joining method of this embodiment can further improve the resistance to shear forces generated between the reinforcing member KB and the constituent members SB, SP compared to conventional techniques.

[0025] The tensile force resisting member 3 is joined to the components SB and SP and fixed directly or indirectly to the end member 2 of the reinforcing member KB in the second direction D2, thereby resisting the tensile force in the second direction D2 received from the reinforcing member KB. As shown in Figures 2, 4, and 7 to 12, the tensile force resisting member 3 is fixed directly or indirectly to the end member 2 so that relative movement of the tensile force resisting member 3 toward the reinforcing member KB in the second direction D2 is suppressed when the tensile force resisting member 3 receives a tensile force in the second direction D2 from the reinforcing member KB. Furthermore, the tensile force resisting member 3 is joined to the components SB and SP so that relative movement of the tensile force resisting member 3 toward the reinforcing member KB in the second direction D2 is suppressed. As a result, when a tensile force in the second direction D2 occurs between the reinforcing member KB and the components SB and SP, the tensile force resisting member 3 is suppressed from moving relative to the reinforcing member KB and the components SB and SP, and resists the tensile force in the second direction D2. Therefore, the tensile force resistance member 3 can transmit the tensile force in the second direction D2 occurring between the reinforcing member KB and the constituent members SB, SP via the end member 2 without attenuating the tensile force or while minimizing attenuation.

[0026] The tensile force resisting members 3 are joined to the structural members SB, SP so as to at least suppress relative movement of the structural members SB, SP toward the reinforcing member KB in the second direction D2; the joining method is not particularly limited. For example, as shown in Figures 2 and 4, if the structural member (beam) SB is an H-shaped steel beam, the tensile force resisting member 3 is joined to the inner surface of the flange SB1 of the H-shaped steel beam, opposite the outer surface to which the end member 2 of the reinforcing member KB is joined. In the example shown in Figure 4, the tensile force resisting member 3 includes two tensile force resisting members 3, 3 arranged on either side of the web SB2 in the third direction D3. The end member 2 and each tensile force resisting member 3 are arranged to sandwich the flange SB1 from both sides of the flange SB1 in the second direction D2 and are fixed to each other by fasteners 4. The tensile force resisting member 3 is fixed to the end member 2 across the flange SB1, and is joined to the flange SB1 without using adhesive. When a tensile force in the second direction D2 occurs between the reinforcing member KB and the component SB, the tensile force resistance member 3 engages with the flange SB1 in the second direction D2, thereby suppressing relative movement of the tensile force resistance member 3 toward the reinforcing member KB in the second direction D2. In the examples shown in FIGS. 2 and 4 , the tensile force resistance member 3 is disposed so as to directly abut the inner surface of the flange SB1 without using an adhesive. However, the tensile force resistance member 3 may be bonded to the inner surface of the flange SB1 with an adhesive such as an epoxy adhesive, or may be disposed so as to indirectly abut the inner surface of the flange SB1 via another member. Furthermore, the tensile force resistance member 3 may be disposed on the outer surface of the flange SB1 on the other side of the pair of flanges SB1, SB1, so as to sandwich the entire component SB together with the end member 2.

[0027] The structure of the tensile force resisting member 3 is not particularly limited as long as it has sufficient rigidity to suppress deformation when resisting at least the tensile force in the second direction D2 generated between the reinforcing member KB and the structural member SB. In an example in which the structural member (beam) SB is an H-shaped steel, the tensile force resisting member 3 is formed of a substantially flat steel plate, as shown in FIGS. 2 and 4. The tensile force resisting member 3 is formed to a size that protrudes outward from the flange SB1 in the third direction D3 so as to be directly fixed to the end member 2 (see FIG. 4). The tensile force resisting member 3 is fixed to the end member 2 by a fixing portion 4 at a portion of the flange SB1 that protrudes outward from the third direction D3. However, as long as the tensile force resisting member 3 can be fixed to the end member 2 by the fixing portion 4, it may be sized so as not to protrude outward from the flange SB1 in the third direction D3.

[0028] As shown in Figures 2 and 4, when the structural member (beam) SB is an H-shaped steel, the connection strength of the tension resisting member 3 to the flange SB1 of the H-shaped steel may be strengthened by an auxiliary connection member 6. The auxiliary connection member 6 is arranged and joined between the surface of the tension resisting member 3 opposite the flange SB1 with which the tension resisting member 3 abuts and the surface of the web SB2. The tension resisting member 3 is joined to the web SB2 and to the auxiliary connection member 6 arranged between the web SB2 and the tension resisting member 3, thereby restricting relative movement of the tension resisting member 3 with respect to the web SB2, and thereby restricting relative movement in the second direction D2 away from the flange SB1 (the side opposite to the reinforcing member KB side). When a tensile force in the second direction D2 occurs between the reinforcing member KB and the structural member SB, the tensile force resisting member 3 receives the force in the second direction D2 toward the reinforcing member KB (lower side in FIG. 4 ) via the fastening member 4 on the outside of the flange SB1 in the third direction D3. Therefore, the portion of the tensile force resisting member 3 adjacent to the web SB2 receives the force in the second direction D2 in a direction away from the flange SB1 (upper side in FIG. 4 ). When the tensile force resisting member 3 receives such a force, the auxiliary connecting member 6 prevents the portion of the tensile force resisting member 3 adjacent to the web SB2 from moving relative to the flange SB1 in the second direction D2 in a direction away from the flange SB1. This allows the tensile force resisting member 3 to more firmly engage with the flange SB1 in the second direction D2, further preventing relative movement toward the reinforcing member KB in the second direction D2.

[0029] The auxiliary connecting member 6 is disposed between the tensile force resisting member 3 and the web SB2 of the H-shaped steel and is capable of suppressing relative movement of the tensile force resisting member 3 in the second direction D2 away from the flange SB1, and its structure and joining method are not particularly limited. In this embodiment, the auxiliary connecting member 6 is configured of a steel material (e.g., an L-shaped steel) that has a substantially L-shaped cross section perpendicular to the first direction D1 and extends along the first direction D1, as shown in Figures 2 and 4. The outer surface of one side 61 of the auxiliary connecting member 6 is joined to the surface of the web SB2 with an adhesive such as an epoxy adhesive, and the outer surface of the other side 62 is directly or indirectly abutted against the surface of the tensile force resisting member 3 adjacent to the web SB2, thereby joining the web SB2 and the tensile force resisting member 3. Since the auxiliary joining member 6 is joined to the tensile force resistance member 3 directly or indirectly by abutting it without being joined with a fixing means such as an adhesive, even if the tensile force resistance member 3 is subjected to a shear force along the first direction D1, the shear force is prevented from being transmitted to the web SB2 via the auxiliary joining member 6.

[0030] As shown in Figures 7 to 12, when the structural member (column) SP is a square steel pipe, the tensile force resisting member 3 is joined to the side surfaces SP2 and SP3 of the square steel pipe. In the example shown in Figures 7 to 12, the tensile force resisting member 3 includes two tensile force resisting members 3, 3, which are respectively arranged on either side of the first side surface SP1 to which the end member 2 of the reinforcing member KB is joined, among the four side surfaces SP1 to SP4 of the square steel pipe, and joined to the second side surface SP2 and the third side surface SP3 which face each other in the third direction D3. The method of joining the tensile force resisting members 3, 3 to the square steel pipe is not particularly limited. For example, the tensile force resisting members 3, 3 may be joined to the opposing side surfaces SP2, SP3 of the square steel pipe with an adhesive such as an epoxy adhesive, as in the examples shown in Figures 7 and 8, or they may be joined to the opposing side surfaces SP2, SP3 of the square steel pipe in the third direction D3 so as to sandwich the square steel pipe with fixing members FM such as through-bolts that pass through the tensile force resisting members 3, 3 and the square steel pipe, as in the examples shown in Figures 9 to 12. The tensile force resisting members 3, 3 may also be joined with fixing members FM in the examples shown in Figures 7 and 8, as in the examples shown in Figures 9 to 12, or they may also be joined with an adhesive in the examples shown in Figures 7 and 8. The tensile force resisting members 3, 3 are joined to the square steel pipes by the fixing members FM so as to sandwich the square steel pipes, and are pressed and fixed against the square steel pipes in the third direction D3. This allows them to resist a force acting away from the square steel pipes in the third direction D3 with greater resistance. This allows the tensile force resisting members 3 to be more firmly joined to the square steel pipes in the third direction D3, further suppressing relative movement in the third direction D3. Furthermore, by fixing the tensile force resisting members 3 to the square steel pipes with the fixing members FM, movement of the tensile force resisting members 3 relative to the square steel pipes during construction can be suppressed, improving workability.

[0031] When the tension resistance members 3 are joined to the square steel pipes, the tension resistance members 3 can be made of steel material (e.g., channel steel) that has a generally U-shaped or C-shaped cross section perpendicular to the first direction D1 and extends along the first direction D1, as shown in FIG. 8 . As shown in FIG. 8 , the tension resistance members 3 have a bottom portion 31 that extends along the second direction D2 and side portions 32, 32 that extend from both ends of the bottom portion 31 in the second direction D2 to one side in the third direction D3. The bottom portions 31, 31 of the two tension resistance members 3, 3 are joined to the second side surface SP2 and the third side surface SP3 of the square steel pipe, respectively, with an adhesive, and the side portions 32, 32 of the two tension resistance members 3 are fixed to the end members 2 of the reinforcing member KB by fixing portions 4. In this embodiment, the tensile force resistance member 3 has a rib 33 extending between the side portions 32, 32 on the bottom portion 31. By having the two side portions 32, 32, and further having the rib 33 extending between the two side portions 32, 32, the tensile force resistance member 3 can suppress deformation of the bottom portion 31 and suppress a decrease in the joining strength (adhesion strength) to the component SP when a tensile force or the like occurs between the reinforcing member KB and the component SP. However, the tensile force resistance member 3 only needs to have at least a portion bonded to the side portions SP2, SP3 of the component SP with an adhesive and a portion fixed to the end member 2 of the reinforcing member KB with the fixing portion 4. For example, the tensile force resistance member 3 may be a steel material (e.g., an L-shaped steel) having a substantially L-shaped cross section perpendicular to the first direction D1. Regardless of the above description, the tensile force resistance member 3 may be formed in a substantially flat plate shape and abut against the fourth side portion SP4 opposite the first side portion SP1, so as to sandwich the entire component SP together with the end member 2.

[0032] When the tensile force resisting member 3 is joined to the square steel pipe, the tensile force resisting member 3 can be, for example, a substantially flat steel plate extending from the square steel pipe to the reinforcing member KB along the second direction D2, as shown in Figures 9 to 12. By joining the square steel pipe and the reinforcing member KB via the tensile force resisting member 3, which is a substantially flat steel plate extending along the second direction D2, when a tensile force occurs between the square steel pipe and the reinforcing member KB in the second direction D2, the tensile force resisting member 3 is primarily subjected to the force along the second direction D2, and is prevented from receiving a force in the direction away from the square steel pipe in the third direction D3. Therefore, the tensile force resisting member 3 is more firmly joined to the square steel pipe in the third direction D3, further suppressing relative movement in the third direction D3.

[0033] In the example shown in Figures 9 to 12, the tensile force resisting member 3 includes two tensile force resisting members 3, 3 arranged on either side of the square steel pipe in the third direction D3. The two tensile force resisting members 3, 3 are respectively joined to the second side SP2 and the third side SP3 of the square steel pipe by adhesive and / or by fixing members FM that penetrate the two tensile force resisting members 3, 3 and the square steel pipe. In the example shown in Figures 9 and 10, the two tensile force resisting members 3, 3 are respectively fixed by fixing members 4 to portions of the reinforcing member KB other than the end member 2 (each of the side faces (flanges) on both sides in the third direction D3). This indirectly fixes the tensile force resisting member 3 to the end member 2. In the example shown in Figures 11 and 12, the two tensile force resisting members 3, 3 are respectively fixed by fixing members 4 to connecting members 8 that abut the end member 2 from the side opposite the square steel pipe in the second direction D2. This indirectly fixes the tension resistance member 3 to the end member 2 .

[0034] As shown in Figures 4, 8, 10, and 12, the fastening members 4 are arranged outside the components SB and SP and directly or indirectly fasten the end member 2 and the tensile resistance member 3 of the reinforcing member KB to each other. By directly or indirectly fastening the end member 2 and the tensile resistance member 3 to each other, the fastening members 4 prevent relative movement of the end member 2 and the tensile resistance member 3 relative to each other in the direction away from each other in the second direction D2. Here, "arranged outside the components SB and SP" means that the fastening members 4 are arranged without at least penetrating the components SB and SP or otherwise deforming the components SB and SP. The fastening members 4 are embodied as bolts extending along the second direction D2 or the third direction D3 and are arranged outside the components SB and SP in the third direction D3 or the second direction D2 without deforming the components SB and SP. 4 and 8, the bolts serving as fastening parts 4 pass through bolt holes provided in the portions of end member 2 that protrude outward from components SB, SP and through bolt holes provided in tensile force resisting member 3, thereby securing end member 2 and tensile force resisting member 3 to each other. In the example shown in FIG. 10, the bolts serving as fastening parts 4 pass through bolt holes provided in tensile force resisting member 3 and through bolt holes provided in reinforcing member KB (the flange on the side surface in the third direction D3), thereby securing tensile force resisting member 3 and reinforcing member KB to each other. In the example shown in FIG. 12, the bolts serving as fastening parts 4 pass through bolt holes provided in tensile force resisting member 3 and through bolt holes provided in connecting member 8, thereby securing tensile force resisting member 3 and connecting member 8 to each other. However, the fixing portion 4 may be any member that is disposed outside the components SB, SP and can directly or indirectly fix the end member 2 and the tensile force resistance member 3 to each other, and that clamps the end member 2 and the tensile force resistance member 3 from the outside in the second direction D2 inside the components SB, SP in the third direction D3 to fix them to each other. Furthermore, the fixing portion 4 may be a fixing member other than a combination of bolts and nuts, such as an adhesive, or may be a portion formed by a fixing means such as welding.The tensile force resisting member 3 can be fixed to the reinforcing member KB and the connecting member 8 in a factory or the like that is different from the construction site, and therefore can be fixed by welding outside the construction site.

[0035] When the structural member SB is an H-beam, the fastening member 4 fastens the end member 2 and the tensile resistance member 3 to each other, spaced apart in the second direction D2 across the flange SB1, on the outside of the third direction D3 of the structural member SB, as shown in FIGS. 2 and 4 . A spacer 7 may be provided between the end member 2 and the tensile resistance member 3 to maintain the distance between them. The provision of the spacer 7 between the end member 2 and the tensile resistance member 3 prevents the distance between the end member 2 and the tensile resistance member 3 from becoming smaller than the thickness of the flange SB1 when the fastening member 4 is tightened, thereby preventing the portion of the tensile resistance member 3 adjacent to the web SB2 from separating from the flange SB1. However, if the end member 2 and the tensile resistance member 3 are formed to abut each other in the second direction D2 on the outside of the third direction D3 of the structural member SB, the provision of the spacer 7 may be omitted.

[0036] In the example shown in Figures 7 and 8, when the structural member SP is a square steel pipe, the fixing portion 4 fixes the end member 2 and the tensile force resisting member 3 to each other while they are in contact with each other in the second direction D2, outside the third direction D3 of the structural member SP. In the example shown in Figures 9 and 10, the fixing portion 4 fixes the tensile force resisting member 3 and the portion of the reinforcing member KB other than the end member 2 while they are spaced apart in the third direction D3. A spacer 7 may be provided between the tensile force resisting member 3 and the reinforcing member KB to maintain the distance between them. This maintains the distance between the tensile force resisting member 3 and the reinforcing member KB even when the bolts serving as the fixing portion 4 are tightened, preventing the portion of the tensile force resisting member 3 joined to the side surfaces SP2 and SP3 of the square steel pipe from moving away from the side surfaces SP2 and SP3 of the square steel pipe in the third direction D3. However, if the tensile force resisting member 3 and the reinforcing member KB are arranged in a state of abutting against each other in the third direction D3, the installation of the spacer 7 can be omitted. In the example shown in Figures 11 and 12, the fixing part 4 fixes the connecting member 8 and the tensile force resisting member 3 in a state of abutting against each other, the connecting member 8 abutting against the end member 2 from the side opposite the square steel pipe in the second direction D2.

[0037] The connecting member 8 is fixed to the tensile force resisting member 3 connected to the square steel pipe, and abuts against the end member 2 from the opposite side of the square steel pipe in the second direction D2, thereby preventing the end member 2 from moving relative to the square steel pipe in the second direction D2 away from the square steel pipe. In the example shown in Figure 12, the connecting member 8 is arranged so as to sandwich the end member 2 between the square steel pipe (and the shear force resisting member 5) in the second direction D2. The connecting member 8 is arranged between the end member 2 and the tensile force resisting member 3, and only needs to prevent the end member 2 from moving relative to the square steel pipe in the second direction D2 away from the square steel pipe, so its structure is not particularly limited. In the example shown in Figures 11 and 12, the connecting member 8 is made of a steel material (e.g., an L-shaped steel) whose cross section perpendicular to the first direction D1 is approximately L-shaped. The connecting member 8 has one side 81 extending along the third direction D3 and directly or indirectly abutting the end member 2, and the other side 82 extending along the second direction D2 and fixed to the tensile force resisting member 3 by the fixing portion 4. The connecting member 8 is joined to the end member 2 by direct or indirect abutment without being joined with a fixing means such as an adhesive, thereby allowing relative movement at least in the third direction D3. Furthermore, as shown in FIG. 12 , a gap is provided between the end member 2 and the tensile force resisting member 3, and a gap is provided between the connecting member 8 and the reinforcing member KB, so that the end member 2 is arranged to be movable relative to the square steel pipe in the third direction D3. In this case, even if a force along the third direction D3 is generated between the square steel pipe and the reinforcing member KB, the end member 2 can move relative to the square steel pipe in the third direction D3, thereby suppressing transmission of the force between the square steel pipe and the reinforcing member KB. However, if the connecting member 8 is joined to the end member 2 using a fixing means such as an adhesive, or if the end member 2 is formed to a size that allows it to abut against the tensile force resistance member 3 in the third direction D3, or if the connecting member 8 is formed to a size that allows it to abut against the reinforcing member KB in the third direction D3, the relative movement of the end member 2 in the third direction D3 with respect to the square steel pipe may be suppressed, and force may be transmitted between the square steel pipe and the reinforcing member KB via the end member 2 and the tensile force resistance members 3, 3.

[0038] As shown in Figures 2, 7, 9, and 11, the shear force resisting members 5 are joined to the structural members SB and SP and are positioned so as to abut the end members 2 in the longitudinal direction (first direction) D1 of the structural members SB and SP. The shear force resisting members 5 abut the end members 2 in the first direction D1 to resist shear forces along the first direction D1 that occur between the end members 2 and the structural members SB and SP. The shear force resisting members 5 resist the shear forces along the first direction D1, thereby suppressing relative movement of the end members 2 with respect to the shear force resisting members 5 and suppressing relative movement of the end members 2 with respect to the structural members SB and SP. As a result, the shear force resisting members 5 can transmit the shear force in the first direction D1 that occurs between the structural members SB and SP and the reinforcing member KB via the end members 2 without attenuation or with limited attenuation. In the joining structure 1 and joining method of this embodiment, instead of resisting the shear force in the first direction D1 by the frictional force between the end member 2 and the constituent members SB, SP as in the conventional technology, the shear force in the first direction D1 is resisted by a shear force resistance member 5 separate from the end member 2 and the constituent members SB, SP, thereby improving the resistance to the shear force generated between the reinforcing member KB and the constituent members SB, SP compared to the conventional technology.

[0039] In this embodiment, as shown in FIGS. 2, 3, 7, 9, and 11, the shear force resistance member 5 has two abutment portions 5a, 5a that are provided facing each other in the longitudinal direction (first direction) D1 of the components SB and SP. The shear force resistance member 5 is positioned relative to the end member 2 so that the two abutment portions 5a, 5a directly abut on both ends 2c, 2c of the end member 2, respectively. This allows the shear force resistance member 5 to restrict relative movement of the end member 2 with respect to the shear force resistance member 5 in both directions in the first direction D1, and to restrict relative movement of the end member 2 with respect to the components SB and SP. However, the shear force resistance member 5 may have only one of the abutment portions 5a, 5a, as long as it can restrict relative movement of the end member 2 in at least one direction in the first direction D1. Conversely, the shear force resistance member 5 may have three or more (four in the illustrated example) abutting portions 5a as shown in Fig. 5 to more reliably resist the shear force in the first direction D1. Furthermore, the shear force resistance member 5 only needs to suppress the relative movement of the end member 2 in the first direction D1, and may be arranged so as to abut indirectly against the end member 2 via another member. As can be seen from Figs. 3 and 5, the abutting portions 5a may be formed by wall portions formed at the ends of the recesses or protrusions.

[0040] When a shear force occurs between the reinforcing member KB and the components SB, SP in the first direction D1, the shear force resisting members 5 are joined to the components SB, SP so as to restrict relative movement of the shear force resisting members 5 relative to the components SB, SP in the first direction D1 in order to resist the shear force. In this embodiment, the shear force resisting members 5 are joined to the components SB, SP with an adhesive such as an epoxy adhesive. When the shear force resisting members 5 are joined to the components SB, SP, it is preferable that they are positioned relative to the end members 2 (or the tensile force resisting members 3) so that a tensile force in the second direction D2 generated between the reinforcing member KB and the components SB, SP does not act on the shear force resisting members 5, or even if it does act, the action of the tensile force is restricted. To this end, in this embodiment, the shear force resisting member 5 is arranged with respect to the end member 2 (or the tension force resisting member 3) such that relative movement of the end member 2 (or the tension force resisting member 3) with respect to the shear force resisting member 5 in the second direction D2 away from the shear force resisting member 5 is permitted only in relation to the end member 2 (or the tension force resisting member 3) (in practice, the end member 2 and the tension force resisting member 3 are fixed to each other directly or indirectly, so that relative movement of the end member 2 and the tension force resisting member 3 with respect to the shear force resisting member 5 is restricted). More specifically, the shear force resisting member 5 is not fixed to the end member 2 (or the tension force resisting member 3) via fixing means such as adhesive or bolts. In this way, the shear force resisting member 5 is not subjected to tensile force in the second direction D2 via the end member 2 (or the tensile force resisting member 3), or even if it is subjected to tensile force, the tensile force is suppressed, thereby suppressing a decrease in the joining strength (adhesion strength) of the shear force resisting member 5 to the constituent members SB, SP, and suppressing a decrease in the resistance to shear force by the shear force resisting member 5. Therefore, the joining structure 1 and joining method of this embodiment can further improve the resistance to shear force generated between the constituent members SB, SP and the reinforcing member KB compared to the conventional technology.

[0041] The shear force resistance members 5 may be positioned between the components SB, SP and the end member 2 in the first direction D1, as long as they are positioned so as to abut the end member 2 in the first direction D1. However, as shown in FIGS. 2, 4, and 7-12, they are preferably positioned between the components SB, SP and the end member 2. By positioning the shear force resistance members 5 between the components SB, SP and the end member 2, when a compressive force in the second direction D2 occurs between the reinforcing member KB and the components SB, SP, the end member 2 presses the shear force resistance members 5 against the components SB, SP, thereby increasing the bonding strength (adhesion) between the components SB, SP. This secures the shear force resistance members 5 more firmly to the components SB, SP, further increasing their resistance to shear forces in the first direction D1. However, the shear force resistance members 5 may also be positioned on both sides of the end member 2 in the first direction D1, sandwiching them, as shown in FIG. 6, for example, without being positioned partially or entirely between the components SB, SP and the end member 2.

[0042] The shear force resistance member 5 may have any structure, as long as it can abut the end member 2 in the first direction D1 and resist shear forces in the first direction D1. In the example shown in FIGS. 2 to 6, the shear force resistance member 5 includes multiple stacked shear force resistance plates 51 to 54 (three layers in the examples shown in FIGS. 2 to 5, and four layers in the example shown in FIG. 6). Because the shear force resistance member 5 is formed from multiple shear force resistance plates 51 to 54, it is more likely to deform in response to deformations of the components SB and SP than if the shear force resistance member 5 were formed as a single member with the same thickness. Even if the components SB and SP deform, the shear force resistance member 5 deforms in response to the deformations of the components SB and SP, thereby maintaining parallelism at the interface between the components SB and SP and preventing a decrease in the bonding strength (adhesion strength) between the components SB and SP. For example, as shown in FIG. 4, when the structural member SB is an H-beam, if a tensile force is generated between the reinforcing member KB and the structural member SB, the tensile force is transmitted between the end member 2 and the tensile-resisting member 3 via the fasteners 4 provided on the outer side of the flange SB1 in the third direction D3. As a result, the tensile force acts on both ends of the flange SB1 in the third direction D3, causing the flange SB1 to deform in the second direction D2 at both ends and to deform concavely toward the reinforcing member KB in the second direction D2 near the center of the third direction D3. In this case, the shear-resisting plates 51-54 of the shear-resisting member 5 can easily deform in response to the deformation of the flange SB1, thereby preventing a decrease in the contact area between the shear-resisting member 5 and the flange SB1 and a decrease in the joining strength (adhesion). Therefore, a decrease in the resistance of the shear-resisting member 5 to shear forces in the first direction D1 can be prevented. However, the shear force resisting member 5 may be formed as a single, substantially plate-shaped member, as shown in FIGS.

[0043] When a shear force occurs between the reinforcing member KB and the structural members SB and SP in the first direction D1, the shear force resistance plates 51-54 are joined to one another so as to restrict relative movement between them in the first direction D1 in order to resist the shear force. In this embodiment, the shear force resistance plates 51-54 are joined to one another with an adhesive such as an epoxy adhesive. The shear force resistance plates 51-54 may have any structure as long as they have sufficient rigidity to restrict deformation of the shear force resistance member 5 as a whole when subjected to a shear force in the first direction D1, and sufficient flexibility to accommodate deformation of the structural members SB and SP when subjected to a tensile force in the second direction D2. Each of the shear force resistance plates 51-54 may be made of, for example, a steel material formed into a substantially flat plate shape.

[0044] Of the multiple shear force resistance plates 51-54, the shear force resistance plates 53, 54 located farthest from the structural members SB, SP are positioned to abut against the end member 2 of the reinforcing member KB. In the example shown in FIG. 3, the shear force resistance plate 53 has a recess formed on its surface facing the end member 2, with abutment portions 5a, 5a formed at both ends of the recess in the first direction D1. In the example shown in FIG. 5, the shear force resistance plate 53 has a recess formed on its surface facing the end member 2, with abutment portions 5a, 5a formed at both ends of the recess in the first direction D1, and a convex portion formed within the recess, with abutment portions 5a, 5a formed at both ends of the convex portion in the first direction D1. In the example shown in FIG. 6, the shear force resistance plate 54 is divided into two plates spaced apart from each other in the first direction D1, with abutment portions 5a, 5a formed at the ends of the two plates facing each other in the first direction D1.

[0045] The shear force resistance plates 53, 54 that directly or indirectly abut the end member 2 require a certain level of adhesive strength to the shear force resistance plates 52, 53 to resist shear forces in the first direction D1, and therefore must be bonded to the shear force resistance plates 52, 53 over a certain area. The shear force resistance plate 53 shown in FIGS. 3 and 5 is formed so that the end member 2 can abut in both directions in the first direction D1 with a single plate. This reduces the installation area of ​​the shear force resistance plate 53 compared to the shear force resistance plate 54 shown in FIG. 6, which has one plate for abutting the end member 2 in each direction in the first direction D1. Furthermore, the shear force resistance plate 54 shown in FIG. 6 can be positioned to abut the end member 2 after the end member 2 is installed. This eliminates the need for pre-machining to fit the shape of the end member 2, as with the shear force resistance plate 53 shown in FIGS. 3 and 5, making it easier to form the shear force resistance member 5.

[0046] Next, a joining method for the joining structure 1 of this embodiment will be described. However, the following description of the joining method is merely an example, and the joining method of the present invention is not limited to the following example. In addition, although several steps will be described below, some steps may be performed in the order described, or in an order different from the order described. Furthermore, one or more of the several steps may be performed by performing one or more other of the several steps. The above description of the joining structure 1 of this embodiment is applicable to the joining method of this embodiment.

[0047] As shown in Figures 2 and 4, and Figures 7 to 12, the joining method of this embodiment includes the steps of joining an end member 2 provided at the end of a reinforcing member KB to constituent members SB and SP, joining a tensile force resistance member 3 to constituent members SB and SP, fixing the end member 2 and the tensile force resistance member 3 to each other directly or indirectly using a fixing portion 4, and joining a shear force resistance member 5 to constituent members SB and SP.

[0048] The step of joining the end member 2 to the structural members SB and SP can be performed, for example, by directly or indirectly fastening the end member 2 and the tensile force resisting member 3 to each other using the fasteners 4. For example, in the example shown in FIGS. 2 and 4 , after the step of joining the shear force resisting member 5 to the structural member SB, the end member 2 is positioned so as to indirectly abut the outer surface of the flange SB1 of the H-shaped steel structural member SB via the shear force resisting member 5, and the tensile force resisting member 3 is positioned so as to abut the inner surface of the flange SB1. The end member 2 can then be joined to the structural member SB by fastening the end member 2 and the tensile force resisting member 3 to each other using the fasteners 4. In the example shown in FIGS. 7 and 8 , after the steps of joining the tensile force resisting member 3 to the structural member SP and joining the shear force resisting member 5 to the structural member SP are performed, the end member 2 is positioned so as to indirectly abut the first side surface SP1 of the rectangular steel pipe structural member SP via the shear force resisting member 5. The end piece 2 can then be joined to the component SP by fastening the end piece 2 and the tension-resisting piece 3 relative to each other by means of the fastening parts 4 .

[0049] The step of joining the end member 2 to the structural members SB and SP can be carried out, for example, by joining the tensile force resisting member 3 to the structural member SP. For example, in the example shown in Figures 9 and 10, after performing the steps of indirectly fixing the tensile force resisting member 3 to the end member 2 by fixing it to a part of the reinforcing member KB other than the end member 2 with the fixing portion 4 and joining the shear force resisting member 5 to the structural member SP, the end member 2 is placed so as to indirectly abut the first side surface SP1 of the structural member SP, which is the square steel pipe, via the shear force resisting member 5. Then, by performing the step of joining the tensile force resisting member 3 to the structural member SP, the end member 2 can be joined to the structural member SP. 11 and 12, after the process of fixing the tensile force resisting member 3 to the connecting member 8 with the fixing portion 4 and joining the shear force resisting member 5 to the component member SP is performed, the end member 2 is placed so as to indirectly abut against the first side surface SP1 of the square steel pipe, which is the component member SP, via the shear force resisting member 5, and the connecting member 8 is placed so as to abut against the end member 2. Thereafter, by performing the process of joining the tensile force resisting member 3 to the component member SP, the end member 2 can be joined to the component member SP.

[0050] In the example shown in FIGS. 2 and 4, the step of joining the tensile force resisting member 3 to the structural members SB and SP can be performed by fixing the end member 2 and the tensile force resisting member 3 to each other using the fasteners 4. More specifically, after the step of joining the shear force resisting member 5 to the structural member SB, the end member 2 is placed indirectly abutting the outer surface of the flange SB1 of the H-shaped steel structural member SB via the shear force resisting member 5, and the tensile force resisting member 3 is placed abutting the inner surface of the flange SB1. The end member 2 and the tensile force resisting member 3 are then fixed to each other using the fasteners 4, thereby joining the tensile force resisting member 3 to the structural member SB. In the example shown in FIGS. 7 and 8, the tensile force resisting member 3 can be joined to the structural member SP by adhesively adhering the tensile force resisting member 3 to the second and third side surfaces SP2 and SP3 of the rectangular steel pipe structural member SP. In addition, in the examples shown in Figures 9 to 12, the tensile force resistance members 3, 3 can be joined to the constituent member SP by fixing them to the opposing second and third side surfaces SP2, SP3 of the square steel pipe using an adhesive and / or by using fixing members FM that penetrate the tensile force resistance members 3, 3 and the square steel pipe that is the constituent member SP.

[0051] In the process of directly or indirectly fixing the end member 2 and the tensile force resistance member 3 to each other using the fixing parts 4, the fixing parts 4 are placed outside the components SB, SP before or after the end member 2 and the tensile force resistance member 3 are placed in predetermined positions relative to the components SB, SP, and the end member 2 and the tensile force resistance member 3 are fixed directly or indirectly to each other using the fixing parts 4 placed outside the components SB, SP.

[0052] The step of joining the shear force resistance members 5 to the components SB and SP can be carried out by adhering the shear force resistance members 5 to the components SB and SP with an adhesive. The shear force resistance members 5 are positioned so as to directly or indirectly abut the end members 2 in the longitudinal direction (first direction) D1 of the components SB and SP in the subsequent step of joining the end members 2 to the components SB and SP. When the shear force resistance member 5 is composed of a plurality of stacked shear force resistance plates 51 to 54 as shown in FIG. 6, and the shear force resistance plate 54 located farthest from the components SB and SP is composed of two plates, the shear force resistance plates 51 to 53 are joined to the components SB and SP, and the end member 2 is joined to the components SB and SP, and then the shear force resistance plate 54 is adhesively adhered to the shear force resistance plate 53.
