Conventionally, columns equipped with diaphragms that serve as joints for joining to beams and other members are known (see Patent Document 1, etc.).

JP 2018-115538 A

In a conventional pillar equipped with a diaphragm, for example, each diaphragm portion provided so as to protrude from each outer surface of the pillar has the same shape and size.
However, when the shapes and sizes of the diaphragm parts that protrude from each outer surface are the same, there is a problem in that the uses of the diaphragm are limited, such as when the same components, such as beams made of the same material, are joined in the same form to each diaphragm part.
The present invention provides a method for using metallic posts that can expand the uses of diaphragms.

The method of using a metal column according to the present invention is a method of using a metal column having a square cross-section and a diaphragm protruding from the peripheral surface of the column formed by four outer surfaces, characterized in that a specific diaphragm portion of the metal column , in which the shape of a specific diaphragm portion protruding from at least one specific outer surface is different from the shape of other diaphragm portions protruding from one or more other outer surfaces, is used as a joining portion for joining to a wooden wall material or a wooden beam material .
In addition, the method of using a metal column according to the present invention is a method of using a metal column having a square cross-section and a diaphragm protruding from the peripheral surface of the column formed by four outer surfaces, characterized in that a specific diaphragm portion of the metal column, in which the shape of a specific diaphragm portion protruding from at least one specific outer surface is different from the shape of other diaphragm portions protruding from one or more other outer surfaces, is used as a joining portion for joining to a wooden wall material or a wooden beam material, and the other diaphragm portions of the metal column are used as joining portions for joining to a metal beam material.
The metal column is also characterized in that it has one specific outer surface, and the protruding length of a specific diaphragm portion protruding from the specific outer surface is longer than the protruding length of each of the other diaphragm portions protruding from the other outer surfaces.
The metal column is also characterized in that the protruding length from each of the specific diaphragm portions protruding from specific outer surfaces facing each other in parallel to each other is longer than the protruding length from each of the other diaphragm portions protruding from the other outer surfaces .
According to the method for using a metal column according to the present invention , for example, it becomes possible to realize a building with a high design quality.
Furthermore, according to the method of using a metal column of the present invention, it becomes possible to realize a composite column-beam joint structure, for example, in which a wooden beam and a metal beam made of different materials are joined to the metal column .

EMBODIMENT 1
As shown in Figures 1 to 3, the metal column 1 serving as a column in embodiment 1 is a metal column having a square tubular cross section and equipped with a diaphragm 10 protruding from the peripheral surface of the column formed by four outer surfaces 1a, 1b, 1c, and 1d.
In this specification, the terms up, down, left, right, front, and rear are defined as directions shown in the drawings.
The metal column 1 is, for example, a square steel pipe provided with a diaphragm 10 protruding from the outer surfaces 1a, 1b, 1c, and 1d, that is, a square steel pipe having no directionality in the cross section and no difference in cross-sectional performance.
As shown in Figures 1 and 2, the diaphragm 10 has a specific diaphragm portion 11 protruding from one specific outer surface 1a of the metallic column 1, and three other diaphragm portions 12, 12, 12 protruding from three other outer surfaces 1b, 1c, 1d of the metallic column 1.
The shape of a specific diaphragm portion 11 protruding from at least one specific outer surface 1a is configured to be different from the shapes of other diaphragm portions 12, 12, 12 protruding from one or more other outer surfaces 1b, 1c, 1d.
In particular, the protruding length of a particular diaphragm portion 11 protruding from a particular outer surface 1a is formed to be longer than the protruding length of each of the other diaphragm portions 12, 12, 12 protruding from the other outer surfaces 1b, 1c, 1d, from the respective outer surfaces 1b, 1c, 1d.

In other words, the specific diaphragm portion 11 is configured to be different from the other diaphragm portions 12 in terms of shape, protruding length from the outer surfaces 1a, 1b, 1c, and 1d, etc.
For example, a specific diaphragm portion 11 is formed in a shape that has a longer protruding length from the outer surface 1 a and is larger in size than the other diaphragm portions 12 .
Specifically, the specific diaphragm portion 11 is formed in a flat plate shape having a plate surface area approximately twice the area of a diaphragm side joint portion 52 of the joint member 5 described later.
A specific diaphragm portion 11 of the metal column 1 in embodiment 1 is used as a joining plate to be joined to a joining member 5 joined to a wooden wall material 2, for example, as described below, and the other diaphragm portion 12 is used as a joining plate to be joined to other members (for example, a metal beam material 16 (see Figure 6) described below), so that it is possible to provide a metal column 1 that can expand the uses of the diaphragm 10.

The metallic column 1 includes, as the diaphragm 10, for example, a plurality of diaphragms 10, 10 . . . spaced apart in the vertical direction.
The diaphragm 10 may be either a through diaphragm or an external diaphragm.
In the case where the diaphragm 10 is a through diaphragm, for example, as shown in Fig. 3, the upper end side of the lower box column part 1E formed by welding together the skin plate steel plates forming the outer sides 1a, 1b, 1c, 1d of the metallic column 1 is welded to the lower side of the steel plate forming the diaphragm 10, and the lower end side of the upper box column part 1F formed by welding together the skin plate steel plates forming the outer sides 1a, 1b, 1c, 1d of the metallic column 1 is welded to the upper side of the steel plate forming the diaphragm 10, so that the diaphragm 10 crosses the metallic column 1. In Fig. 3, the symbol 1S denotes a backing plate, and S denotes a welded part.

Hereinafter, a description will be given of a joint structure between the metal column 1 and a wooden wall material 2 serving as a wooden member, which is an example of use of the metal column 1 according to the first embodiment.
That is, by using the metal column 1 of embodiment 1, a joint structure can be realized in which a specific diaphragm portion 11 of the diaphragm 10 of the metal column 1 is joined to a wooden wall material 2 via a joining means 3, as shown in Figures 4 to 8.

The wooden wall material 2 is a wall panel made of wood such as CLT (Cross Laminated Timber), laminated timber, LVL (Laminated Veneer Lumber), or solid wood.
Additionally, CLT, as defined in Notification No. 3079 of the Ministry of Agriculture, Forestry and Fisheries, is "a general material made by arranging or gluing planks or small square timber (including those which have been adjusted by joining and gluing them lengthwise with their grain directions roughly parallel to each other) in the width direction with their grain directions roughly parallel to each other, and then laminating and gluing them together mainly with their grain directions roughly perpendicular to each other to create a structure of three or more layers."
That is, CLT is generally a type of wood constructed by gluing together multiple boards so that the grain directions of the boards cross at right angles, and is known as cross-laminated timber.
Generally, laminated lumber is wood made by bonding together a number of boards so that the grain directions of the boards are parallel to each other.
Moreover, LVL is generally a wood material in which a plurality of veneer panels are laminated and glued together in a manner that is parallel to the grain direction of the veneer panels.
The wooden wall material 2 may be a general wall board for construction, or a wall board for forming a hanging wall (a hanging wall), or a wall board for forming a waist wall, or a wall board for forming a sleeve wall, or the like.
The wooden wall material 2 is formed, for example, from a rectangular flat wall board of a predetermined thickness having rectangular board surfaces 21, 21 that are long in the left-right (horizontal) direction.

The wooden wall material 2 has a recess 8 formed by cutting out a corner of a rectangular wooden wall material that is the basis of the wooden wall material 2.
That is, as shown in Figure 7, the upper recess 8 of the wooden wall material 2 formed by cutting out the upper corner of the wooden wall material 2 has a first supported surface 8A formed by a vertical plane perpendicular to the upper end face 23 and parallel to the side end face 22, and a second supported surface 8B formed by a horizontal plane perpendicular to the side end face 22 and parallel to the upper end face 23.
In other words, the upper recess 8 of the wooden wall material 2 is a notched recess consisting of a first supported surface 8A formed by a vertical surface extending downward from the side edge of the upper end face 23, and a second supported surface 8B formed by a horizontal surface extending from the extended end of the first supported surface 8A to the side end face 22.
Similarly, the lower recess 8 of the wooden wall material 2, formed by cutting out the lower corner of the wooden wall material 2, has a first supported surface 8A formed by a vertical plane perpendicular to the lower end face 24 and parallel to the side end face 22, and a second supported surface 8B formed by a horizontal plane perpendicular to the side end face 22 and parallel to the lower end face 24.
In other words, the lower recess 8 of the wooden wall material 2 is a notched recess consisting of a first supported surface 8A formed by a vertical surface extending upward from the side edge of the lower end face 24, and a second supported surface 8B formed by a horizontal surface extending from the extended end of the first supported surface 8A to the side end face 22.

In other words, the wooden wall material 2 has side end faces 22 which are the end faces in the left-right direction, which is the long dimension of the board surface 21, and upper end faces 23 and lower end faces 24 which are the end faces in the up-down direction, which is the short dimension of the board surface 21, and is formed by a rectangular flat wall panel having recesses 8 on the upper and lower sides of the side end faces 22.
Furthermore, the wooden wall material 2 is provided with an upper insertion groove 25 that opens to the upper first supported surface 8A and the upper end face 23, a lower insertion groove 25 that opens to the lower first supported surface 8A and the lower end face 24, and a plurality of pin through holes 26, 26... that are formed to penetrate one board surface 21, the insertion groove 25, and the other board surface 21 and allow a drift pin 26 to pass through.

The joining means 3 is configured to include a joining member 5 joined to the wooden wall material 2 and a diaphragm-side joining means for joining the joining member 5 to the diaphragm 10.

As shown in Figures 4, 7, and 8, the joint member 5 is configured to include a wooden-wall-material-side joint 51 as a joint joined to the wooden wall material 2, a first bearing surface 7A that contacts the first bearing surface 8A of the wooden wall material 2 positioned to face the metal column 1 and suppresses rotation of the wooden wall material 2, a second bearing surface 7B that contacts the second bearing surface 8B of the wooden wall material 2 positioned to intersect with the column core 1C of the metal column 1 and suppresses vertical movement of the wooden wall material 2, and a diaphragm-side joint 52 that is joined to the diaphragm 10.

The rotation of the wooden wall material 2 mentioned above refers to the rotation of the wooden wall material 2 around an axis that is a virtual horizontal line perpendicular to the material axis 2C (see Figure 5) of the wooden wall material 2 joined to the metal column 1.
In addition, the vertical movement of the wooden wall material 2 refers to the movement of the wooden wall material 2 joined to the metal column 1 in a direction perpendicular to the material axis (vertical direction).

That is, as shown in Figures 7 and 8, the joint member 5 is composed of a bearing surface structure 7, a wooden wall material side joint portion 51 for the wooden wall material 2, and a diaphragm side joint portion 52 for the diaphragm 10 of the metal column 1.
The wooden wall material side joint 51 is constituted by the other end portion of a rectangular vertical plate 51A having a vertical surface formed by a rectangular plate surface that is long in the left-right direction, which is closer to the wooden wall material 2, and one end portion 51a of the vertical plate 51A, which is closer to the diaphragm 10, functions as a reinforcing member for the support surface structure 7.
In addition, the diaphragm side joint 52 is composed of one end portion of a rectangular horizontal plate 52A having a horizontal surface formed by a rectangular plate surface that is long in the left-right direction, which is closer to the diaphragm 10, and the other end portion 52a of the horizontal plate 52A, which is closer to the wooden wall material 2, is positioned so that the plate surface faces the upper end surface 23 or lower end surface 24 of the wooden wall material 2 and functions as a cover plate that covers the insertion groove 25.

As shown in FIG. 8, the support surface structure 7 is composed of a horizontal plate portion forming the diaphragm side joint 52, a support plate 7a, a middle side reinforcing plate 7c, and an end side reinforcing plate 7d formed by three vertical plates connected to the horizontal plate portion and arranged to extend vertically from one plate surface side of the horizontal plate portion, and a horizontal plate 7b arranged to be connected to the extended end sides of the support plate 7a, the middle side reinforcing plate 7c, and the end side reinforcing plate 7d.

The support plate 7a is configured to extend from a position near the boundary between the diaphragm side joint 52 and the other end portion 52a on one plate surface of the horizontal plate 52A, and is configured as a flat plate having a first support surface 7A formed by a vertical surface parallel to the first supported surface 8A.
The end side reinforcement plate 7d is arranged to extend from the edge (the edge located on the metal column 1 side) of the diaphragm side joint 52 on one plate surface of the horizontal plate 52A, and is composed of a flat plate having a vertical surface parallel to the first support surface 7A.
The intermediate side reinforcement plate 7c is arranged to extend from the diaphragm side joint 52 on one plate surface of the horizontal plate 52A, and is positioned midway between the support plate 7a and the end side reinforcement plate 7d, and is composed of a flat plate with a vertical surface parallel to the first support surface 7A.
The horizontal plate 7b is constituted by a flat plate having a second bearing surface 7B formed by a horizontal surface extending from the extension end of the first bearing surface 7A.

As shown in Figures 7 and 8, the vertical plate 51A forming the wooden wall material side joint 51 is formed by a flat plate having one long edge connected to a midpoint between the front and rear of one of the plate surfaces of the horizontal plate 52A and having a plate surface perpendicular to the plate surface of the horizontal plate 52A and the first support surface 7A.
The vertical plate 51A has one short edge side that constitutes the one end portion 51a that functions as a reinforcing member for the support surface structure 7, penetrating the midpoint between the front and rear of the support plate 7a and the intermediate side reinforcing plate 7c, and this one short edge side is connected to the end side reinforcing plate 7d, and the other short edge side of the vertical plate 51A functions as the wooden wall material side joint 51.
The plate surface opposite the plate surface forming the second support surface 7B of the horizontal plate 7b is configured to be perpendicular to the plate surface of the vertical plate 51A, so that the plate surface opposite the plate surface forming the second support surface 7B of the horizontal plate 7b is in contact with one end side of the other long side edge of the vertical plate 51A.

As shown in FIG. 7, the diaphragm-side joint portion 52 of the joint member 5 is formed with bolt through holes 55, 55 . . .
Further, the wooden-wall-material-side joint portion 51 is formed with pin through holes 56 , 56 . . . that correspond to the plurality of pin through holes 26 , 26 .
In addition, the specific diaphragm portion 11 is formed with bolt through holes 65 , 65 . . . corresponding to the bolt through holes 55 , 55 . . . of the diaphragm side joint portion 52 .

That is, the joining means 3 is composed of a joining member 5 joined to the wooden wall material 2 and a diaphragm side joining means that joins the joining member 5 to the diaphragm 10, and the diaphragm side joining means is composed of a bolt 61 and a nut 62 that join the plate surface of the diaphragm side joining portion 52, which is the plate portion of the joining member 5 that are overlapped with each other, to the plate surface of a specific diaphragm portion 11, which is the plate portion of the diaphragm 10, while bringing them into surface contact (see Figure 4).
Therefore, the diaphragm side joining means is constituted by bolt joining means for joining the plate portions of the joining member 5 overlapping each other and the plate portion of the specific diaphragm portion 11 .
In other words, the joining means 3 joining the diaphragm 10 of the metal column 1 to the wooden wall material 2 is composed of a joining member 5 joined to the wooden wall material 2, and a diaphragm side joining means consisting of bolts 61 and nuts 62 that join the diaphragm side joining portion 52 of the joining member 5 that are overlapped on top of each other to a specific diaphragm portion 11 of the diaphragm 10.

An example of a construction procedure for a joint structure between a metal column 1 and a wooden wall material 2 using the metal column 1 according to embodiment 1 will be described.
First, at a factory or on-site, the joint members 5, 5 are attached in advance to the upper and lower sides of the side end face 22 of the wooden wall material 2. The joint members 5, 5 having the same structure are attached upside down to the upper and lower sides of the side end face 22 of the wooden wall material 2.
That is, the wooden wall material side joint portion 51 of the joining member 5 is inserted into the insertion groove 25, the second bearing surface 7B is brought into contact with the second supported surface 8B, and the first bearing surface 7A is brought into surface contact with the first supported surface 8A of the wooden wall material 2, so that the pin through hole 26 of the wooden wall material 2 and the pin through hole 56 of the wooden wall material side joint portion 51 of the joining member 5 are aligned, and then the drift pin 27 is inserted into the pin through holes 26, 56, 26 in an engaged state, thereby joining the wooden wall material 2 and the joining member 5.
In addition, the joint member 5 is configured so that, when attached to the wooden wall material 2, the outer surface 7f of the end side reinforcing plate 7d is positioned on the same plane as the side end surface 22 of the wooden wall material 2 (see Figure 4).
In addition, the wooden wall material 2, to which connecting members 5, 5 are attached on the upper and lower sides of the side end face 22, is formed so that the length between the upper plate surface of the diaphragm side joint 52 of the upper connecting member 5 and the lower plate surface of the diaphragm side joint 52 of the lower connecting member 5 corresponds to the length between specific diaphragm portions 11, 11 of the upper and lower diaphragms 10, 10 that protrude from the outer surface 1a of the metal column 1.
Then, the wooden wall materials 2 to which the joint members 5 are attached are installed on the left and right sides in front of the outer surface 1a of the metal column 1. That is, the left end side of the wooden wall material 2 installed on the right side is positioned on the right side between the upper and lower specific diaphragm parts 11, 11, and the right end side of the wooden wall material 2 installed on the left side is positioned on the left side between the upper and lower specific diaphragm parts 11, 11, so that the side end faces 22, 22 of the left and right wooden wall materials 2, 2 and the outer surfaces 7f, 7f of the end side reinforcing plates 7d, 7d of the upper and lower joint members 5, 5 are butted together in alignment with the center line 1ac between the face widths of the outer surface 1a of the metal column 1.
Then, a nut 62 is fastened to the tip end of a bolt 61 which has been inserted through the bolt through hole 55 of the diaphragm side joint portion 52 and the bolt through hole 65 of the specific diaphragm portion 11 .
As a result of the above, the left and right wooden wall materials 2, 2 are each joined to the metal column 1 by the joining means 3 composed of the joining member 5 joined to the wooden wall material 2 and the diaphragm side joining means consisting of the bolts 61 and nuts 62 that join the diaphragm side joining portions 52 of the overlapping joining members 5 to a specific diaphragm portion 11 of the diaphragm 10.

In this case, as shown in Figure 5, a specific diaphragm portion 11 of the diaphragm 10 of the metal column 1 is joined to the wooden wall materials 2, 2 so that the material axis 2C of the wooden wall material 2 is eccentric from the column core 1C of the metal column 1.
Therefore, for example, as shown in FIG. 6, in a building configured so that the inside of the building can be easily seen from the outside through the window glass 15, a structure can be realized in which a wooden wall material 2 such as a hanging wall (downward wall) at the edge of the window glass 15 is joined to a metal column 1. In this case, a highly designed building can be realized in which the metal column 1 is not visible between the left and right wooden wall materials 2, 2 when the building is viewed from the outside. That is, a wooden wall material 2 such as a hanging wall (downward wall) at the edge of the window glass 15 can be joined to a specific diaphragm portion 11, the uses of the diaphragm 10 can be expanded, and a metal column 1 that can realize a highly designed building can be provided. In other words, by using the specific diaphragm portion 11 of the metal column 1 as a joining portion for joining to the wooden wall material 2, the uses of the diaphragm 10 can be expanded, and a highly designed building can be realized.
In addition, in Figure 6, reference numeral 16 denotes a metallic beam material such as a steel beam joined to the other diaphragm portion 12 of the metal column 11, reference numeral 17 denotes a floor, and reference numeral 18 denotes a steel beam (small beam) joined to the metallic beam material 16.

According to the joining structure between the metal column 1 and the wooden wall material 2 using the metal column 1 of embodiment 1, the wooden wall material 2 is joined to a specific diaphragm portion 11 of the diaphragm 10 of the metal column 1 using a joining means 3 including a joining member 5 joined to the wooden wall material 2 and a bolt 61 and a nut 62 constituting a diaphragm side joining means that joins the joining member 5 to the diaphragm 10, so that the wooden wall material 2 can be easily joined to the metal column 1.
In addition, it becomes possible to join a specific diaphragm portion 11 of the diaphragm 10 of the metal column 1 to the wooden wall materials 2, 2 so that the material axis 2C of the wooden wall material 2 is located at a position eccentric to the column core 1C of the metal column 1. In other words, since it becomes possible to join the wooden wall material 2 to the specific diaphragm portion 11, it is possible to provide a metal column 1 that can expand the uses of the diaphragm 10.
Furthermore, according to the joint structure between the metal column 1 and the wooden wall material 2 using the metal column 1 of embodiment 1, the wooden wall material 2 having the recess 8 at the corner portion is used, and the connecting member 5 having the support surface structure 7 is used. Therefore, by making the first support surface 7A of the connecting member 5 and the first supported surface 8A of the wooden wall material 2 in surface contact with each other, it is possible to suppress rotation of the wooden wall material 2, and by making the second support surface 7B of the connecting member 5 and the second supported surface 8B of the wooden wall material 2 in surface contact with each other, it is possible to realize a suitable joint structure that can suppress vertical movement of the wooden wall material 2.

The first supported surface 8A and the first supporting surface 7A that are in surface contact with each other do not have to be completely vertical, but may be nearly vertical. In other words, the first supported surface 8A and the first supporting surface 7A may be formed so as to be in surface contact with each other and suppress rotation of the wooden wall material 2.
Similarly, the second supported surface 8B and the second supporting surface 7B that are in surface contact with each other do not have to be completely horizontal, but may be nearly horizontal. In other words, the second supported surface 8B and the second supporting surface 7B may be surfaces that are formed so as to be in surface contact with each other and suppress the vertical movement of the wooden wall material 2.

Furthermore, as shown in Figure 6, when a normal diaphragm 10A for joining a metal beam material 16 such as a steel beam is provided between the upper and lower diaphragms 10, 10, that is, a conventionally known diaphragm 10A in which the diaphragm portions protruding from the four outer surfaces 1a, 1b, 1c, 1d of the metal column 1 are all formed in the same diaphragm portion (e.g., other diaphragm portion 12), for example, a groove for removing the diaphragm portion of the diaphragm 10A can be formed in the rear panel surface (back surface) of the left and right wooden wall materials 2, 2.
6, a column-beam joint structure can be realized in which specific diaphragm portions 11, 11 of the upper and lower diaphragms 10, 10 are joined to the wooden wall material 2, and other diaphragm portions 12 of the upper diaphragm 10 and the middle diaphragm 10A are joined to the metal beam material 16. In other words, by using the metal column 1 equipped with the diaphragms 10, 10A, 10, a composite joint structure can be realized in which the metal column 1 is joined to a wooden wall material 2 and a metal beam material 1Z, which are made of different materials.

Furthermore, in a configuration in which a specific diaphragm portion 11 of the diaphragm 10 of the metal column 1 is joined to the wooden wall materials 2, 2 so that the material axis 2C of the wooden wall material 2 is in an eccentric position from the column core 1C of the metal column 1, a joining plate attached by welding or the like to the metal column 1 and the rear panel surface (back surface) side of the wooden wall materials 2, 2 may be joined using a locking screw or the like, although this is not shown in the figure.
In addition, in such a case where a joining plate attached to the metal column 1 by welding or the like is joined to the rear panel (back surface) side of the wooden wall materials 2, 2 using locking screws or the like, a recess (not shown) may be formed on the rear panel (back surface) side of the left and right wooden wall materials 2, 2 to avoid the outer surface 1a of the metal column 1.

The diaphragm side joining means may be constructed by welding means that joins the diaphragm side joining portion 52 of the overlapping joining members 5 to a specific diaphragm portion 11 of the diaphragm 10. In this case, the bolt through holes 65, 65... are not required in the specific diaphragm portion 11.

It is also possible to use a wooden wall material having a first support surface 8A but no second support surface 8B, and to use a second connecting member having a first support surface 7A but no second support surface 7B.
Conversely, it is also possible to use a wooden wall material that has a second support surface 8B but does not have a first support surface 8A, and to use a second connecting member that has a second support surface 7B but does not have a first support surface 7A.
This is because even with this configuration, a joint structure can be realized that can suppress rotation or vertical movement of the wooden wall material.

In the above, the joining means between the wooden wall material 2 and the joining member 5 may be any joining means other than the drift pin, for example, a joining means using bolts and nuts may be used.
Further, although an example has been given in which steel plates are used as the joining members 5, these joining members may be plate-shaped members other than steel plates, for example, plate-shaped members made of metals other than steel, or plate-shaped members other than metals may be used.

EMBODIMENT 2
As shown in Figure 9, a metal column 1 is provided with a diaphragm 10 formed so that the protruding length from each of specific diaphragm portions 11, 11 protruding from specific outer surfaces 1a, 1d facing each other in parallel is longer than the protruding length from each of other diaphragm portions 12, 12 protruding from the other outer surfaces 1b, 1c.
That is, the specific diaphragm portion 11 is formed in a shape that has a longer protruding length from the outer surface and is larger in size than the other diaphragm portions 12 .
Then, a column-beam joint structure is realized in which specific diaphragm parts 11, 11 of the metal column 1 are used as joint parts for joining to a wooden beam 2Z, and other diaphragm parts 12, 12 of the metal column 1 are used as joint parts for joining to a metallic beam 1Z such as an H-shaped steel beam. In other words, by using the metal column 1, it becomes possible to realize a composite column-beam joint structure in which a wooden beam 2Z and a metallic beam 1Z, which are made of different materials, are joined to the metal column 1.
The specific diaphragm portion 11 and the wooden beam 2Z may be joined by joining a joining member attached to the wooden beam 2Z to the specific diaphragm portion 11 with a bolt and nut, or by welding, or the specific diaphragm portion 11 and the wooden beam 2Z may be joined with a drift pin, etc. For example, when joining with a bolt and nut or a drift pin, a through hole 11H is formed in the specific diaphragm portion 11.
The other diaphragm portion 12 and the metallic beam material 1Z may be joined by welding or with bolts and nuts.
According to the second embodiment, it is possible to provide a metallic column 1 that enables the diaphragm 10 to be used in a wider range of applications.
In addition, since it becomes possible to join the wooden beam 2Z to a specific diaphragm portion 11, 11 which is formed in a shape that has a longer protruding length from the outer surface and a larger size compared to the other diaphragm portions 12, 12, the joining strength between the wooden beam 2Z and the metal column 1 can be improved and the strength difference between the joining strength between the wooden beam 2Z and the metal column 1 and the joining strength between the metal beam 1Z and the metal column 1 can be reduced, which is preferable.
In addition, in the second embodiment, a wooden wall material 2 may be joined instead of the wooden beam material 2Z.

The numbers of the pin through holes and bolt through holes may be freely set as appropriate depending on the required strength, the number of drift pins, and the number of bolts.
Moreover, it is preferable to use high strength bolts (high tension bolts) as the above-mentioned bolts.

In addition, although an example has been shown in which a square steel pipe is used as the metal column 1, the metal column 1 may also be a steel pipe with a triangular, circular, polygonal, or other cross section.

Although wooden wall material 2 and wooden beam material 2Z are given as examples of wooden members, the wooden members may be, for example, wooden flooring materials or other materials.

Incidentally, the pillars of the present invention do not have to be metal pillars, and may be pillars made of other materials, for example, wooden pillars.
In other words, the pillar of the present invention may be a pillar that has a diaphragm protruding from the peripheral surface of the pillar, and is configured so that the shape of a part of the diaphragm protruding from the peripheral surface of the pillar is different from the shape of the other part, thereby enabling the use of the diaphragm to be expanded.
