[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-85872 Summary of the Invention [Problem to be solved by the invention]

[0004] It is difficult to connect the upper column to the lower column when the upper column is twisted relative to the lower column and the upper column is tilted relative to the lower column.

[0005] A problem of the present disclosure is to properly connect an upper column to a lower column when the upper column is twisted relative to the lower column and when the upper column is tilted relative to the lower column. [Means for solving the problem]

[0006] The joint member of the first embodiment is a joint member that connects a lower post with a rectangular cross section to an upper post with a rectangular cross section that is twisted and tilted relative to the lower post and has other sides that are non-planar with all of the side surfaces of the lower post, and has a tubular main body with a rectangular upper edge that faces the lower edge of the upper post and a rectangular lower edge that faces the upper edge of the lower post, and each side plate provided on the main body is composed of a triangular upper plate member with a portion of the upper edge as one side, and a triangular lower plate member with a portion of the lower edge as one side and connected to the upper plate member by welding.

[0007] According to the above aspect, each side plate provided on the main body includes a triangular upper plate member connected to the upper plate member by welding and a triangular lower plate member, thereby making it possible to appropriately connect the upper and lower columns without using castings when the upper column is twisted relative to the lower column and tilted relative to the lower column.

[0008] The joint member of the second aspect is the joint member described in the first aspect, and comprises an upper diaphragm attached between the upper edge of the main body portion and the lower edge of the upper column, and a lower diaphragm attached between the lower edge of the main body portion and the upper edge of the lower column.

[0009] According to the above aspect, an upper diaphragm is attached between the upper edge of the main body and the lower edge of the upper column, and a lower diaphragm is attached between the lower edge of the main body and the upper edge of the lower column. As a result, when the axial force applied to the upper column is transmitted by the connection member to the lower column, the upper and lower diaphragms prevent the main body from expanding, thereby enabling the axial force applied to the upper column to be transmitted effectively to the lower column.

[0010] The joint member of the third aspect is the joint member of the second aspect, and is provided with a bracket to which a beam is connected, the bracket having an H-shaped cross section and a pair of flanges connected by welding to the edges of the upper diaphragm and the lower diaphragm, and a web spanning the pair of flanges and having its edges formed along the side plates, and the thickness of the bracket is thicker than the thickness of the side plates.

[0011] According to the above-mentioned aspect, the edge of the web of the bracket to which the beam is connected is formed along the side plate. Furthermore, the thickness of the bracket is made thicker than the thickness of the side plate. As a result, when the joint member transmits the axial force applied to the upper column to the lower column, the web whose edge is formed along the side plate prevents the main body from expanding, thereby enabling the axial force applied to the upper column to be effectively transmitted to the lower column.

[0012] The joint member of the fourth aspect is the joint member of the first aspect, in which a transmission member is provided inside the main body portion to transmit the load received by one of the side plates to the other side plate facing the one side plate.

[0013] According to the above aspect, a horizontal load applied to one side plate can be effectively transmitted to the other side plate.

[0014] A joint member according to a fifth aspect is the joint member according to the fourth aspect, wherein the transmission member is concrete filled inside the main body portion.

[0015] According to the above aspect, the load can be transmitted in a simpler manner than when a cross rib is used to transmit the load. [Effects of the Invention]

[0016] The present disclosure provides for proper connection of the upper column to the lower column when the upper column is twisted relative to the lower column and when the upper column is tilted relative to the lower column. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] An example of a joint member according to an embodiment of the present disclosure will be described with reference to Figures 1 to 9. Arrow H in each figure indicates the vertical direction, i.e., the up-and-down direction of the joint member; arrow W in each figure indicates the width direction of the joint member, which is perpendicular to arrow H and also indicates the horizontal direction; and arrow D in each figure indicates the depth direction of the joint member, which is perpendicular to arrows H and W and also indicates the horizontal direction. All drawings used in the following description are schematic. Furthermore, the dimensional relationships and ratios of each element shown in the drawings do not necessarily correspond to reality.

The lower column 100 has a rectangular tubular cross section and extends vertically, with four side surfaces 100a, 100b, 100c, and 100d formed on the lower column 100. The upper edge 102 of the lower column 100 is rectangular and arranged on a horizontal plane.

[0021] -Upper column 110- The upper column 110 is a rectangular steel pipe column, and is arranged above the lower column 100 with the joint member 10 in between.

[0049] [Lower diaphragm 56] The lower diaphragm 56 is a so-called through diaphragm, and as shown in FIGS. 3 and 4, the thickness direction of the lower diaphragm 56 is the up-down direction, and the lower diaphragm 56 is disposed so as to cover the lower edge 20b of the main body 20 from below.

[0050] The outer shape of the lower diaphragm 56 is rectangular, and the edge of the lower diaphragm 56 protrudes horizontally from the lower end edge 20b of the main body 20. In addition, the lower diaphragm 56 is formed with a plurality of through holes 56a.

[0052] [Upper diaphragm 50] The upper diaphragm 50 is a so-called through diaphragm, and as shown in FIGS. 3 and 4, the thickness direction of the upper diaphragm 50 is the up-down direction, and the upper diaphragm 50 is disposed so as to cover the upper edge 20a of the main body 20 from above.

[0053] The upper diaphragm 50 has a rectangular outer shape, and when viewed from above, has a shape obtained by rotating the lower diaphragm 56 counterclockwise around the center of gravity of the lower diaphragm 56.

[0055] [Short Bracket 60] The short bracket 60 is a bracket for attaching the beam 120 (see Figure 1) to the joint member 10, and is arranged on one side in the width direction of the main body 20, as shown in Figures 3 and 4. The short bracket 60 is an example of a bracket.

[0056] The short bracket 60 has an H-shaped cross section and includes a pair of flanges 62, 64 spaced apart in the vertical direction, and a web 66 spanning the pair of flanges 62, 64. The upper flange 62 abuts against one side of the upper diaphragm 50 and is connected to the upper diaphragm 50 by welding. The lower flange 64 abuts against one side of the lower diaphragm 56 and is connected to the lower diaphragm 56 by welding.

[0057] Furthermore, the flange length of the flange 62 is longer on the upper diaphragm 50 side than on the beam 120 side. Similarly, the flange length of the flange 64 is longer on the lower diaphragm 56 side than on the beam 120 side.

[0059] Furthermore, the plate thickness of the pair of flanges 62, 64 and the plate thickness of the web 66 are similar, and these plate thicknesses are thicker than the plate thickness of the upper plate members 24, 36, 30, 42 and the plate thickness of the lower plate members 26, 38, 32, 44. In other words, the plate thickness of the short bracket 60 is thicker than the plate thickness of the side plates 22, 28, 34, 40.

[0060] [Short Bracket 70] The short bracket 70 is a bracket for attaching the beam 130 (see FIG. 1) to the joint member 10, and is arranged on the other side in the width direction of the main body 20, as shown in FIGS. 3 and 4. The short bracket 70 is an example of a bracket.

[0063] On the other hand, an edge 76a of the web 76 on the side plate 34 side is formed to fit along the side plate 34, and is butted against the side plate 34 and connected to the side plate 34 by welding (see FIG. 7).

[0064] Furthermore, the plate thickness of the pair of flanges 72, 74 and the plate thickness of the web 76 are similar, and these plate thicknesses are thicker than the plate thickness of the upper plate members 24, 36, 30, 42 and the plate thickness of the lower plate members 26, 38, 32, 44. In other words, the plate thickness of the short bracket 70 is thicker than the plate thickness of the side plates 22, 28, 34, 40.

[0065] [Short Bracket 80] The short bracket 80 is a bracket for attaching the beam 140 (see Figure 1) to the joint member 10, and is arranged on the front side in the depth direction relative to the main body 20, as shown in Figures 3 and 4. The short bracket 80 is an example of a bracket.

[0066] The short bracket 80 has an H-shaped cross section and includes a pair of flanges 82, 84 spaced apart in the vertical direction, and a web 86 spanning the pair of flanges 82, 84. The upper flange 82 abuts against one side of the upper diaphragm 50 and is connected to the upper diaphragm 50 by welding. The lower flange 84 abuts against one side of the lower diaphragm 56 and is connected to the lower diaphragm 56 by welding.

[0067] Furthermore, the flange length of the flange 82 is longer on the upper diaphragm 50 side than on the beam 140 side. Similarly, the flange length of the flange 84 is longer on the lower diaphragm 56 side than on the beam 140 side.

[0068] On the other hand, an edge 86a of the web 86 on the side of the side plate 28 is formed so as to fit along the side plate 28, and is butted against the side plate 28 and connected to the side plate 28 by welding.

[0069] Furthermore, the plate thickness of the pair of flanges 82, 84 and the plate thickness of the web 86 are similar, and these plate thicknesses are thicker than the plate thickness of the upper plate members 24, 36, 30, 42 and the plate thickness of the lower plate members 26, 38, 32, 44. In other words, the plate thickness of the short bracket 80 is thicker than the plate thickness of the side plates 22, 28, 34, 40.

[0070] (action) Next, a description will be given of the construction process of the joint member 10. As shown in Figures 8 and 9, the joint member 10 is carried into the construction site in a state where it is connected to the upper post 110 and the lower post 100.

[0071] At the construction site, the upper end of a column (not shown) is connected to the lower edge of the lower column 100 by welding, and the lower edge of a column (not shown) is connected to the upper edge of the upper column 110 by welding. Furthermore, as shown in FIG. 1, a beam 120 is connected to the short bracket 60 of the connection member 10 using a splice plate and bolts and nuts (not shown). Similarly, a beam 130 is connected to the short bracket 70 of the connection member 10 using a splice plate and bolts and nuts (not shown). Furthermore, a beam 140 is connected to the short bracket 80 of the connection member 10 using a splice plate and bolts and nuts (not shown).

[0072] Furthermore, in this embodiment, the columns are concrete-filled steel tube structures (CFTs), and the interiors of the lower columns 100, the joint members 10, and the upper columns 110 are filled with concrete on-site, as shown in Fig. 7. The concrete 90 filled inside the joint members 10 (see Fig. 7) is an example of a transmission member.

[0073] When the structure including the joint member 10 is completed, the axial force applied to the upper column 110 is transmitted to the lower column 100 via the joint member 10, and the axial force applied to the beam 120 is transmitted to the beam 130 via the joint member 10.

[0074] (summary) As described above, in the joint member 10, the side plate 22 of the main body 20 is composed of a triangular upper plate member 24 and a triangular lower plate member 26, and the side plate 28 is composed of a triangular upper plate member 30 and a triangular lower plate member 32. Furthermore, the side plate 34 is composed of a triangular upper plate member 36 and a triangular lower plate member 38, and the side plate 40 is composed of a triangular upper plate member 42 and a triangular lower plate member 44. Furthermore, the upper edge 20a of the main body 20 faces the lower edge 112 of the upper post 110, and the lower edge 20b of the main body 20 faces the upper edge 102 of the lower post 100. This allows the upper column 110 and the lower column 100 to be properly connected without using castings when the upper column 110 is twisted relative to the lower column 100 and tilted relative to the lower column 100.

[0075] In addition, in the joint member 10, an upper diaphragm 50 is attached between the upper edge 20a of the main body 20 and the lower edge 112 of the upper column 110, and a lower diaphragm 56 is attached between the lower edge 20b of the main body 20 and the upper edge 102 of the lower column 100. As a result, when the joint member 10 transmits the axial force applied to the upper column 110 to the lower column 100, the upper diaphragm 50 and the lower diaphragm 56 prevent the main body 20 from expanding, so that the axial force applied to the upper column 110 can be transmitted effectively to the lower column 100.

[0076] In addition, in the connection member 10, the edges of the webs 66, 76, 86 of the short brackets 60, 70, 80 to which the beams 120, 130, 140 are connected are formed along the side plates 22, 28, 34. Furthermore, the plate thickness of the short brackets 60, 70, 80 is made thicker than the plate thickness of the side plates 22, 28, 34, 40. As a result, when the connection member 10 transmits the axial force applied to the upper column 110 to the lower column 100, the webs 66, 76, 86 prevent the main body 20 from expanding, and the axial force applied to the upper column 110 can be transmitted effectively to the lower column 100.

[0077] Furthermore, in the joint member 10, concrete 90 is filled inside the main body 20. This allows the horizontal load applied to the side panel 22 to be effectively transmitted to the side panel 34. In other words, the load applied from the beam 120 to the joint member 10 can be effectively transmitted to the beam 130 via the concrete 90.

[0078] Furthermore, in the joint member 10, concrete 90 is filled inside the main body 20. This allows the load to be transmitted from the side plate 22 to the side plate 34 in a simpler manner than, for example, when a cross rib is used to transmit the load from the side plate 22 to the side plate 34.

[0079] Although the present disclosure has been described in detail with respect to a specific embodiment, it will be apparent to those skilled in the art that the present disclosure is not limited to such an embodiment and that various other embodiments are possible within the scope of the present disclosure. For example, in the above embodiment, the joint member 10 is provided with three short brackets 60, 70, and 80, but the joint member 10 may not be provided with any short brackets, or may be provided with one, two, or four short brackets.

[0080] In addition, in the above embodiment, concrete 90 is filled inside the joint member 10 as a transmission member, but a cross rib may be placed inside the joint member 10 as a transmission member. However, in this case, the effect achieved by using concrete as a transmission member will not be achieved.

[0081] In the above embodiment, the joint member 10 includes the upper diaphragm 50 and the lower diaphragm 56, but the joint member 10 may not include the diaphragms. In this case, however, the effects achieved by including the diaphragms are not achieved.

[0082] Although not specifically described in the above embodiment, the welding of the corners of the main body 20 may be fillet welding, groove welding, or the like. [Explanation of symbols]
