[0009] (First embodiment) A structural member and a building according to an embodiment of the present disclosure will be described below with reference to the drawings. The structural member according to this embodiment is used for, for example, columns and beams of a building. First, a building including the structural member according to this embodiment will be described.

[0010] (building) FIG. 1 is a perspective view showing a framework of a building 1 according to an embodiment. As shown in Fig. 1, the building 1 includes columns 11, beams 12, and a girder 13. Hereinafter, in this embodiment, as shown in Fig. 1, the direction in which the columns 11 extend is referred to as the up-down direction D1, the direction in which the beams 12 extend among directions perpendicular to the up-down direction D1 is referred to as the beam direction D2, and the direction in which the girder 13 extends, which is perpendicular to the up-down direction D1 and the beam direction D2, is referred to as the girder direction D3.

[0011] Fig. 2 is a front view showing a state in which a structural member 2 according to the first example is used in a column 11 and a beam 12 of a building 1. In the building 1 of this embodiment, the column 11 and the beam 12 are formed symmetrically with respect to a reference line R shown in Fig. 2. The reference line R is an imaginary line extending in the vertical direction D1 at the center of the building 1 in the beam direction D2. Fig. 2 shows only one side of the reference line R, and the other side is omitted. FIG. 3 is an enlarged view of part III shown in FIG. FIG. 4 is a view taken along the arrow IV in FIG. Hereinafter, only one of the symmetrically formed columns 11 and beams 12 will be described, and the other will be omitted as it is the same as the other.

[0012] As shown in Figures 1 and 2, the lower end of the column 11 in the vertical direction D1 is connected to a foundation F provided at the construction site of the building 1. The upper end of the column 11 in the vertical direction D1 is connected to the end of the beam 12 on the side farther from the reference line R in the beam direction D2, as shown in Figures 2 and 3. The beams 12 extend upward from the columns 11 toward the reference line R. In this embodiment, the beams 12 are inclined with respect to the horizontal plane. As shown in Figures 2 and 3, the end of the beam 12 on the reference line R side in the beam direction D2 is connected to the end of the other beam 12 on the reference line R side. In this embodiment, as shown in FIG. 1, a plurality of components (hereinafter referred to as unit components 2A) each having a column 11 and a beam 12 connected thereto are provided at intervals along the girder direction D3.

[0013] 1, the girder 13 connects a plurality of unit components 2A provided at intervals along the girder direction D3 to each other. For example, known shaped steel 20 such as C-shaped steel or angle steel is suitably used for the girder 13. The beam 12 and the girder 13 may be, for example, the framework of the roof of the building 1.

[0014] FIG. 5 is an enlarged view of the V portion shown in FIG. 6 is a cross-sectional view taken along the line VI-VI in FIG. FIG. 7 is an enlarged view of part VII shown in FIG. As shown in Fig. 2, a plurality of girders 13 are provided at intervals in the beam direction D2 on the upper part of the beam 12. Specifically, the girders 13 may be provided at the end of the beam 12 farther from the reference line R in the beam direction D2, as shown in Figs. 3 and 4, for example. The girders 13 may be provided at the middle part of the beam 12 in the beam direction D2, as shown in Figs. 5 and 6. The girders 13 may be provided at the end closer to the reference line R in the beam direction D2, as shown in Fig. 7.

[0015] The beam 12 and the girder 13 are connected, for example, as follows. That is, as shown in FIGS. 2 to 7, the beam 12 and the girder 13 are fixed by bolts B via brackets Br with the upper surface of the beam 12 and the lower surface of the girder 13 in contact with each other. Specifically, the beam 12 and the bracket Br are fixed to each other by bolts B, and the bracket Br and the girder 13 are fixed to each other by bolts B, thereby connecting the beam 12 and the girder 13. For example, a known angle iron may be used for the bracket Br. In this embodiment, the length of the girder 13 is equal to, for example, the length of the building 1 in the girder direction D3. Such a girder 13 may be formed integrally with, for example, one member 13a, or may be formed by combining multiple members 13a. When multiple members 13a are combined to form the girder 13, the length of each member 13a may be determined, for example, in accordance with the spacing between the unit components 2A in the building 1. In this way, for example, as shown in FIGS. 4 and 6, each of the members 13a may be connected to the beam 12 at the end in the girder direction D3. The building 1 according to this embodiment is configured as described above.

[0016] (Structural members) In this embodiment, the columns 11 and beams 12 are formed by the structural members 2 according to this embodiment. In other words, the building 1 according to this embodiment includes the structural members 2 according to this embodiment as the columns 11 and beams 12. The building 1 includes the columns 11 formed by the structural members 2 and the beams 12 formed by the structural members 2. First, the structural member 2 according to this embodiment will be described using the beam 12 of the above-described building 1 as an example.

[0017] As shown in Figure 2, the structural member 2 includes a web member 21, a first shaped steel 22, a second shaped steel 23, a third shaped steel 24, and a fourth shaped steel 25. Hereinafter, in the description of the structural member 2 used for the beam 12, the direction along the beam direction D2 of the building 1 will be referred to as the long axis direction. In the structural member 2 used for the beam 12, the long axis direction may be parallel to the horizontal direction or may be inclined.

[0018] The web material 21 is a plate-like member arranged along the longitudinal direction. As shown in FIG. 2, the web material 21 is arranged so that its main surface faces the girder direction D3. In this embodiment, the main surface of the web material 21 is trapezoidal. The width of the web material 21 decreases as it approaches the center of the building 1 including the structural member 2. In the structural member 2 used in the beam 12, the width of the web material 21 refers to the dimension in the up-down direction D1. In the structural member 2 used in the beam 12, the width of the web material 21 can also be said to be the height of the web material 21. Specifically, as shown in FIG. 2 , the width of the end of the web member 21 connected to the column 11 in the beam direction D2 is greater than the width of the end on the reference line R side. By forming the web member 21 in this trapezoidal shape, the distance between the first and second shaped steels 22 and 23 that sandwich one end of the web member 21 and the third and fourth shaped steels 24 and 25 that sandwich the other end of the web member 21 can be changed from one side to the other in the longitudinal direction when forming the structural member 2, as described below. Furthermore, by reducing the width of the web member 21 on the side closer to the reference line R, the strength of the portion of the web member 21 located near the center of the building 1 can be maintained at a necessary level while reducing the weight of the web member 21 in that portion. This can contribute to reducing the weight and cost of the structural member 2.

[0019] In this embodiment, the width of the web material 21 is determined according to the shear force. That is, in this embodiment, the width of the web material 21 is determined according to the shear force of the web material 21 generated by the load acting on the web material 21 in the building 1. Here, in the building 1, a particularly large load acts at the connection between the column 11 and the beam 12. In contrast, the load acting around the center of the building 1 in the beam direction D2 is relatively small. Therefore, in the web material 21 of the structural member 2 used for the beam 12, the shear force decreases from the column 11 side toward the reference line R side. Therefore, the width of the web material 21 decreases from the column 11 side toward the reference line R side. This preferably reduces the weight of the web material 21 in the structural member 2 while maintaining sufficient strength.

[0020] The first shaped steel 22, the second shaped steel 23, the third shaped steel 24, and the fourth shaped steel 25 extend in the longitudinal direction. Hereinafter, when there is no need to distinguish between the first shaped steel 22, the second shaped steel 23, the third shaped steel 24, and the fourth shaped steel 25, they may be referred to as shaped steel 20. In this embodiment, each of the structural steels 20 has a portion extending in at least two directions in a cross section perpendicular to the longitudinal direction. In this embodiment, each of the structural steels 20 may include, for example, a C-shaped steel or an angle steel. In other words, each of the structural steels 20 may be formed, for example, by a C-shaped steel or an angle steel. In this embodiment, each of the structural steels 20 is a C-shaped steel as shown in FIG. 6. Each of the structural steels 20 that is a C-shaped steel has a portion extending in two directions in the cross section: a direction parallel to the web material 21 and a direction perpendicular to the direction parallel to the web material 21, as shown in FIG. 6, for example. Even when each of the structural steels 20 is an angle steel, it also has a portion extending in two directions in the cross section: a direction parallel to the web material 21 and a direction perpendicular to the direction parallel to the web material 21.

[0021] In this embodiment, the structural member 2 is formed as follows. That is, as shown in FIG. 6 , the first shaped steel 22 and the second shaped steel 23 sandwich one end of the web member 21 in a cross section perpendicular to the longitudinal direction, and the third shaped steel 24 and the fourth shaped steel 25 sandwich the other end of the web member 21 in a cross section perpendicular to the longitudinal direction. In the structural member 2 used for the beam 12, the first shaped steel 22 and the second shaped steel 23 sandwich the upper end of the web member 21, and the third shaped steel 24 and the fourth shaped steel 25 sandwich the lower end of the web member 21. As shown in FIG. 6 , the first shaped steel 22 and the second shaped steel 23 and the web member 21, and the third shaped steel 24 and the fourth shaped steel 25 and the web member 21 are each fixed by a bolt B. A plurality of bolts B are provided at intervals along the longitudinal direction. With the above-described configuration, the web material 21 is reinforced by each of the structural steels 20. In this way, the structural member 2 according to this embodiment is formed.

[0022] In this embodiment, the lengths of the web material 21 and the structural steel 20 in the longitudinal direction are approximately equal. This makes it easier to transport these components before the structural member 2 is formed. Note that, as shown in FIG. 3 , in the structural member 2 used for a column 11 described below, the lengths of the third structural steel 24 and the fourth structural steel 25 may be shorter than the lengths of the first structural steel 22 and the second structural steel 23 in order to connect the beam 12 and the column 11. In this embodiment, the fact that the lengths of the respective components in the longitudinal direction are approximately equal includes such cases.

[0023] In this embodiment, the length in the longitudinal direction of each of the web material 21 and the structural steel 20 is 12 m or less. More specifically, the length in the longitudinal direction of the material constituting each of the web material 21 and the structural steel 20 is 12 m or less. This preferably makes it possible for each of these components to be transported on the bed of a well-known, general trailer. The web material 21 may be integrally formed from a single plate material, or may be formed by appropriately joining multiple plate materials. Each of the structural steels 20 may be integrally formed from a single member 20M, or may be formed by appropriately joining multiple members 20M as in this embodiment. In this embodiment, multiple members 20M adjacent in the longitudinal direction are connected by a connecting member 20C. As shown in FIG. 5, for example, a pair of connecting members 20C are arranged with the multiple members 20M sandwiched between them in the vertical direction D1. An example of the connecting member 20C is a splice plate 21b.

[0024] In this embodiment, as shown in FIG. 7 , the end of the structural member 2 used for the beam 12, which is closer to the reference line R, is connected to the beam 12 located on the opposite side of the reference line R via a connecting plate 21a. Specifically, at the end of the structural member 2 closer to the reference line R, each of the structural steels 20 protrudes toward the reference line R along the longitudinal direction relative to the web member 21. The end of the web member 21 on the reference line R side is located closer to the column 11 than the reference line R. At the end of the structural member 2 closer to the reference line R, each of the ends of the structural steels 20 protruding toward the reference line R clamps a connecting plate 21a. The connecting plate 21a is located on both sides of the reference line R in the beam direction D2. The connecting plate 21a and the web member 21 are connected by a splice plate 21b. This connects the beams 12 located on both sides of the reference line R. It is preferable that the splice plates 21b are disposed on both sides of the connecting plate 21a and the web material 21 in the girder direction D3 (thickness direction). The above-described configurations form the structural member 2 used for the beam 12 in the building 1 of this embodiment.

[0025] Next, we will explain the structural member 2 used for the columns 11 of the above-mentioned building 1. Below, we will explain the differences between the structural member 2 used for the beams 12 and the structural member 2 used for the columns 11, and will not explain the rest of the details as they have the same configuration as the structural member 2 used for the beams 12. The long axis direction of the structural member 2 used in the pillar 11 is aligned with the vertical direction D1. In the structural member 2 used in the pillar 11, the width of the web member 21 refers to the dimension of the web member 21 in the beam direction D2. In the structural member 2 used in the pillar 11, the long axis direction may be parallel to or inclined relative to the vertical direction D1. In the structural member 2 used in the column 11, the width of the trapezoidal web material 21 becomes smaller the closer it is to the foundation F of the building 1 that includes the structural member 2. Specifically, as shown in Figure 2, in the structural member 2 used in the column 11, the width of the upper end of the web material 21 in the vertical direction D1 is greater than the width of the lower end.

[0026] In the structural member 2 used for the column 11, the first shaped steel 22 and the second shaped steel 23 sandwich the end of the web material 21 on the side farther from the reference line R in the beam direction D2. In addition, the third shaped steel 24 and the fourth shaped steel 25 sandwich the end of the web material 21 on the side closer to the reference line R in the beam direction D2. In addition, as will be described later, in order to enable connection between the column 11 and the beam 12, in the structural member 2 used for the column 11, the lengths of the third shaped steel 24 and the fourth shaped steel 25 are shorter than the lengths of the first shaped steel 22 and the second shaped steel 23. In addition, the upper ends of the third shaped steel 24 and the fourth shaped steel 25 are located at a position lower than the upper ends of the first shaped steel 22 and the second shaped steel 23 in the vertical direction D1. In the above respects, the structural member 2 used for the column 11 differs from the structural member 2 used for the beam 12.

[0027] (Column and beam connection structure) The following describes the connection structure between the structural member 2 used in the beam 12 and the structural member 2 used in the column 11. In the description of the connection structure, the structural member 2 used in the beam 12 and the structural member 2 used in the column 11 will be simply referred to as the beam 12 and the column 11, respectively. The same applies to the second embodiment described below.

[0028] As shown in Figs. 2 and 3, the column 11 and the beam 12 are connected at the upper end of the column 11 in the up-down direction D1 and the end of the beam 12 on the side farther from the reference line R. At this time, each end of the shaped steel 20 of the beam 12 protrudes in the longitudinal direction beyond the web material 21. Each of the shaped steels 20 of the beam 12 clamps the web material 21 of the column 11 at its end. Each of the shaped steels 20 of the beam 12 is fixed to the web material 21 of the column 11 with a bolt B. At this time, in order to prevent the third shaped steel 24 and the fourth shaped steel 25 of the column 11 (the shaped steel 20 on the reference line R side) from interfering with each of the shaped steels 20 of the beam 12, the third shaped steel 24 and the fourth shaped steel 25 of the column 11 may be formed shorter than the first shaped steel 22 and the second shaped steel 23. In this way, it is preferable to shorten the shaped steel 20 of the column 11 without shortening the shaped steel 20 of the beam 12, thereby making it easier to transmit the bending moment from the beam 12 to the column 11. In addition, the web material 21 of the column 11 and the web material 21 of the beam 12 are connected to each other by a splice plate 21b. The above-described components form the structural member 2 used for the column 11 in the building 1 of this embodiment.

[0029] As described above, in the structural member 2 according to this embodiment, the web material 21 is arranged along the longitudinal direction. In a cross section perpendicular to the longitudinal direction, one end of the web material 21 is clamped between the first shaped steel 22 and the second shaped steel 23. The other end of the web material 21 is clamped between the third shaped steel 24 and the fourth shaped steel 25. This allows the structural member 2 to be formed, for example, by joining procured shaped steel or plate materials with bolts B or the like. Therefore, the structural member 2 can be formed without special processing of the procured shaped steel or plate materials. Therefore, the structural member 2 can be formed, for example, without going through a primary steel material processor or a steel frame fabricator. As a result, the cost of the structural member 2 can be reduced while shortening the delivery time.

[0030] The first shaped steel 22, the second shaped steel 23, the third shaped steel 24, and the fourth shaped steel 25 include C-shaped steel or angle steel. By using general-purpose shaped steel in this way, it is possible to further reduce the cost of the shaped steel. Furthermore, by reducing the time required to procure the shaped steel, it is possible to further shorten the delivery time of the structural member 2.

[0031] Furthermore, the width of the web material 21 is determined in accordance with the shear force. Specifically, the width of the web material 21 is determined in accordance with the shear force acting on the web material 21. This allows the web material 21 to have sufficient strength in the structural member 2. This makes it easier to ensure the strength of the structural member 2.

[0032] Here, for example, when the structural member 2 is used as a beam 12 of a building 1, the load acting on the portion of the structural member 2 located in the center of the building 1 is relatively small. Therefore, the width of the web material 21 becomes smaller the closer it is to the center of the building 1 including the structural member 2. This makes it possible to reduce the weight of the web material 21 in that portion while keeping the strength of the portion of the structural member 2 located in the center of the building 1 to a necessary level. This can therefore easily contribute to reducing the weight and cost of the structural member 2.

[0033] Furthermore, the main surface of the web material 21 is trapezoidal. For example, by appropriately adjusting the length of one side and the other side of the web material 21 in the longitudinal direction, it is possible to appropriately change the distance between the first shaped steel 22 and the second shaped steel 23 that sandwich one end of the web material 21 and the third shaped steel 24 and the fourth shaped steel 25 that sandwich the other end of the web material 21 from one side to the other in the longitudinal direction. This makes it easier to make the shape of the structural member 2 more suitable to the conditions of use, etc.

[0034] Furthermore, the lengths in the longitudinal direction of each of the web material 21, the first shaped steel 22, the second shaped steel 23, the third shaped steel 24, and the fourth shaped steel 25 are generally equal. By making the lengths of the members that form the structural member 2 generally equal in this way, it becomes easier to transport the members together, for example.

[0035] Here, the length of a member that can be transported by the bed of a typical trailer is, for example, 12 m or less. Therefore, the length in the longitudinal direction of each of the web material 21, the first shaped steel 22, the second shaped steel 23, the third shaped steel 24, and the fourth shaped steel 25 is 12 m or less. This allows each of these members to be transported by a typical trailer. In other words, it is possible to eliminate the need to transport each of these members using a special transportation method.

[0036] Furthermore, the building 1 according to this embodiment includes the structural members 2 of the present disclosure as columns 11 and beams 12. This allows the cost of the structural members 2 of the building 1 to be reduced while also shortening the delivery time.

[0037] Furthermore, the building 1 includes a column 11 and a beam 12 formed by the structural member 2 according to the embodiment, and at the boundary between the column 11 and the beam 12, a web material 21 having a larger area than the web material 21 arranged on the column 11 or the beam 12 is arranged. This makes it possible to more reliably connect the column 11 and the beam 12 in the building 1. This makes it easier to ensure the strength of the building 1.

[0038] (Second embodiment) Next, a structural member 2 according to a second embodiment of the present disclosure will be described with reference to FIGS. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted, with only the differences being described. FIG. 8 is a front view showing a state in which a structural member 2 according to the second example is used for a column 11 and a beam 12 of a building 1. As shown in FIG. FIG. 9 is an enlarged view of part IX shown in FIG. FIG. 10 is an enlarged view of the X portion shown in FIG. FIG. 11 is an enlarged view of the portion XI shown in FIG.

[0039] The structural member 2 of the second embodiment is provided with a plurality of web materials 21. Specifically, in the structural member 2 of the second embodiment, a plurality of web materials 21 are provided along the longitudinal axis direction, as shown in FIG. In the second embodiment, each of the structural steels 20 is formed, for example, by connecting a plurality of members 20M along the longitudinal direction. In this case, it is preferable that each of the plurality of web members 21 is located at a connection between the members 20M arranged side by side along the longitudinal direction, as shown in Fig. 10, for example. This makes it possible to easily connect the members 20M that form each of the structural steels 20. The web material 21 may be provided at a location other than the connection portion between the members 20M, as shown in Fig. 8. In the second embodiment, the web materials 21 adjacent to each other in the beam direction D2 are connected to each other by being clamped by the respective structural steels 20.

[0040] The web materials 21 may or may not be spaced equally apart in the beam direction D2. If the web materials 21 are not spaced equally apart, it is preferable to increase the spacing near the center of the building 1 where a relatively small load acts, and decrease the spacing on the outside of the building 1 where a relatively large load acts.

[0041] As in the first embodiment, the first shaped steel 22 and the second shaped steel 23 are fixed to the web member 21, and the third shaped steel 24 and the fourth shaped steel 25 are fixed to the web member 21 by bolts B. A plurality of bolts B are provided at intervals along the longitudinal direction. In this case, the plurality of bolts B arranged along the longitudinal direction in the structural member 2 may be provided at locations other than the connection portions between the shaped steels 20. In this case, it is preferable to provide liner materials (not shown) between the first shaped steel 22 and the second shaped steel 23, and between the third shaped steel 24 and the fourth shaped steel 25.

[0042] In the second embodiment, the multiple web members 21 include those with different widths. The multiple web members 21 have different widths depending on the location where they are attached to the structural member 2. Here, the width of the web member 21 refers to the dimension in the up-down direction D1 for a structural member 2 attached to a beam 12, and refers to the dimension in the beam direction D2 for a structural member 2 attached to a column 11. In the second embodiment, the width of each of the multiple web members 21 is determined according to the shear force of the web member 21 generated by a load acting on the web member 21 in the building 1. In this way, it is preferable to ensure that the web member 21 has sufficient strength in the structural member 2 by, for example, increasing the width of the web member 21 in a portion where the load is likely to act.

[0043] In the second embodiment, the multiple web members 21 include those of different lengths. The multiple web members 21 have different lengths depending on the location where they are attached to the structural member 2. Here, the length of the web member 21 refers to the dimension in the beam direction D2 for a structural member 2 attached to a beam 12, and refers to the dimension in the up-down direction D1 for a structural member 2 attached to a column 11. In the second embodiment, the length of each of the multiple web materials 21 is determined, for example, according to the shear force of the web material 21 caused by the load acting on the web material 21 in the building 1. Here, as described above, the load acting on the portion of the structural member 2 located at the center of the building 1 is relatively small. Therefore, when the structural member 2 is used for the beam 12 of the building 1, it is preferable to make the width of the web material 21 smaller the closer it is to the center of the building 1 including the structural member 2. This makes it possible to reduce the weight of the web material 21 near the center of the building 1. In the second embodiment, for example, as shown in Fig. 8, the length of the web material 21 provided at the connection portion between the shaped steels 20 may be longer than the length of the web material 21 provided at a location other than the connection portion between the shaped steels 20. This may enable the connection between the shaped steels 20 to be more reliably performed.

[0044] In the second embodiment, the end of the structural member 2 used for the beam 12 that is closer to the reference line R is connected to the beam 12 located on the opposite side of the reference line R via a web member 21, as shown in Fig. 11. The web member 21 arranged at the end of the beam 12 that is closer to the reference line R is positioned on both sides in the beam direction D2, with the reference line R as the center. By clamping such a web member 21 between each of the structural steels 20 of the beams 12 located on both sides of the reference line R, each of the beams 12 located on both sides of the reference line R is connected. The above-described configurations form the structural member 2 used for the beam 12 in the building 1 of the second embodiment.

[0045] (Column and beam connection structure) Next, a connection structure between the structural member 2 used in the beam 12 and the structural member 2 used in the column 11 in the second embodiment will be described. The connection structure between the pillar 11 and the beam 12 is generally the same as in the first embodiment. In the second embodiment, a web material 21 having a larger area than the web material 21 disposed on either the pillar 11 or the beam 12 is disposed at the boundary between the pillar 11 and the beam 12. This preferably ensures the strength of the connection between the pillar 11 and the beam 12 in the second embodiment.

[0046] As described above, the structural member 2 according to the second embodiment has a plurality of web materials 21. For example, by providing a plurality of web materials 21 at intervals along the longitudinal direction, the size of each of the plurality of web materials 21 can be reduced. Therefore, for example, the cost of the web material 21 can be reduced compared to when the web material 21 is formed from a single plate material.

[0047] The plurality of web materials 21 may have different widths. For example, by increasing the width of the web material 21 in a portion of the structural member 2 that is more susceptible to load, the cost of the web material 21 can be reduced while ensuring that the structural member 2 has sufficient strength.

[0048] The web materials 21 also include those of different lengths. For example, by appropriately adjusting the lengths of the multiple web materials 21, it is possible to appropriately change the distance between the first shaped steel 22 and the second shaped steel 23 that clamp one end of the web material 21 and the third shaped steel 24 and the fourth shaped steel 25 that clamp the other end of the web material 21 from one side to the other in the longitudinal direction. This makes it easier to make the shape of the structural member 2 more suitable to the conditions of use, etc.

[0049] The technical scope of the present disclosure is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present disclosure. For example, the structural steel 20 may be any structural steel other than the above-mentioned C-shaped steel and angle steel. Furthermore, the web material 21 does not have to be trapezoidal in shape, and may be, for example, a parallelogram, a rectangle, or any other polygonal shape depending on the conditions such as the strength required for the building 1. Furthermore, the lengths of the web material 21 and the structural steel 20 in the longitudinal direction do not have to be equal to each other, and may be 12 m or more.

[0050] In addition, within the scope of the present disclosure, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modified examples may be combined as appropriate.

[0051] (Addendum) The structural members and buildings according to the above-described embodiments can be understood, for example, as follows.

[0052] <1> A structural member according to one embodiment of the present disclosure comprises a web material arranged along a longitudinal direction, and a first shaped steel, a second shaped steel, a third shaped steel, and a fourth shaped steel that extend in the longitudinal direction and have portions that extend in at least two directions in a cross section perpendicular to the longitudinal direction, wherein the first shaped steel and the second shaped steel clamp one end side of the web material in the cross section, and the third shaped steel and the fourth shaped steel clamp the other end side of the web material in the cross section.

[0053] According to the above structural member, the web material is arranged along the longitudinal direction. In a cross section perpendicular to the longitudinal direction, one end of the web material is clamped between the first and second shaped steel beams. The other end of the web material is clamped between the third and fourth shaped steel beams. This allows the structural member to be formed, for example, by joining procured shaped steel beams or plate materials with bolts or the like. Therefore, the structural member can be formed without special processing of the procured shaped steel beams or plate materials. Therefore, the structural member can be formed, for example, without going through a primary steel material processing manufacturer or a steel frame fabricator. As a result, the cost of the structural member can be reduced while shortening the delivery time.

[0054] <2> the above <1> In the structural member according to the above, a configuration may be adopted in which the first section steel, the second section steel, the third section steel, and the fourth section steel include C-section steel.

[0055] Furthermore, the first, second, third, and fourth shaped steels include C-shaped steel. By using general-purpose shaped steel in this way, it is possible to further reduce the cost of shaped steel. Furthermore, by reducing the time required to procure shaped steel, it is possible to further shorten the delivery time for structural components.

[0056] <3> the above <1> or <2> In the structural member according to the above, a configuration may be adopted in which the first section steel, the second section steel, the third section steel, and the fourth section steel include angle steels.

[0057] Furthermore, the first, second, third, and fourth shaped steels include angle steel. By using general-purpose shaped steel in this way, it is possible to further reduce the cost of shaped steel. Furthermore, by reducing the time required to procure shaped steel, it is possible to further shorten the delivery time for structural components.

[0058] <4> the above <1> from <3> In the structural member according to any one of the above aspects, a configuration may be adopted in which a plurality of the web materials are provided.

[0059] In addition, a plurality of web materials are provided. For example, by providing a plurality of web materials at intervals along the longitudinal direction, the size of each of the plurality of web materials can be reduced. Therefore, for example, compared to when the web material is formed from a single plate material, the cost of the web material can be reduced.

[0060] <5> the above <1> from <4> In the structural member according to any one of the above aspects, a configuration may be adopted in which the plurality of web materials include those having different widths.

[0061] The plurality of web materials may also include those of different widths. For example, by increasing the width of the web material in a portion of the structural member that is more susceptible to load, the cost of the web material can be reduced while still providing sufficient strength to the structural member.

[0062] <6> the above <1> from <5> In the structural member according to any one of the above aspects, a configuration may be employed in which the width of the web material is determined in accordance with a shear force.

[0063] Furthermore, the width of the web material is determined according to the shear force. Specifically, the width of the web material is determined according to the shear force acting on the web material. This allows the web material to have sufficient strength in the structural member. This makes it easier to ensure the strength of the structural member.

[0064] <7> the above <1> from <6> In any one of the structural members, the longitudinal direction may be parallel to or inclined with respect to the horizontal direction, and the width of the web material may become smaller as it approaches the center of a building including the structural member.

[0065] For example, when a structural member is used as a beam in a building, the load acting on the structural member at the center of the building is relatively small. Therefore, the width of the web material is made smaller the closer it is to the center of the building including the structural member. This makes it possible to reduce the weight of the web material in the center of the building while maintaining the strength of the structural member at a necessary level. This can easily contribute to reducing the weight and cost of the structural member.

[0066] <8> the above <1> from <7> In the structural member according to any one of the above aspects, a configuration may be adopted in which the plurality of web materials include those of different lengths.

[0067] The web members may also be of different lengths. For example, by appropriately adjusting the lengths of the multiple web members, the distance between the first and second shaped steel members that clamp one end of the web member and the third and fourth shaped steel members that clamp the other end of the web member can be appropriately changed from one side to the other in the longitudinal direction. This makes it easier to make the shape of the structural member more suitable for the conditions of use, etc.

[0068] <9> the above <1> from <8> In the structural member according to any one of the above aspects, a configuration may be adopted in which the main surface of the web material has a trapezoidal shape.

[0069] The main surface of the web material is trapezoidal. For example, by appropriately adjusting the length of one side and the other side of the web material in the longitudinal direction, the distance between the first and second shaped steel members that clamp one end of the web material and the third and fourth shaped steel members that clamp the other end of the web material can be appropriately changed from one side to the other in the longitudinal direction. This makes it easier to make the shape of the structural member more suitable for the conditions of use, etc.

[0070] <10> the above <1> from <9> In the structural member according to any one of the above embodiments, a configuration may be adopted in which the lengths of the web material, the first steel section, the second steel section, the third steel section and the fourth steel section in the longitudinal direction are approximately equal.

[0071] Furthermore, the lengths of the web material, the first section steel, the second section steel, the third section steel, and the fourth section steel in the longitudinal direction are all roughly the same. By making the lengths of the components that make up the structural member roughly the same in this way, it becomes easier to transport the components together, for example.

[0072] <11> the above <1> from <10> In any one of the structural members according to the above embodiment, the length of each of the web material, the first steel section, the second steel section, the third steel section and the fourth steel section in the longitudinal direction may be 12 m or less.

[0073] Here, the length of a member that can be transported by the bed of a typical trailer is, for example, 12 m or less. Therefore, the length in the longitudinal direction of each of the web material, first section steel, second section steel, third section steel, and fourth section steel is 12 m or less. This allows each of these members to be transported by a typical trailer. In other words, it is possible to eliminate the need to transport each of these members using a special transportation method.

[0074] <12> The building according to one embodiment of the present disclosure is <1> from <11> The structural member according to any one of the above aspects is included as a pillar.

[0075] According to the above-mentioned building, the structural member of the present disclosure is included as a pillar, which reduces the cost of the structural member of the building and shortens the delivery time.

[0076] <13> The building according to one embodiment of the present disclosure is <1> from <11> The structural member according to any one of the above aspects is included as a beam.

[0077] Furthermore, the structural members of the present disclosure are included as beams, which can reduce the cost of structural members for buildings and shorten delivery times.

[0078] <14> A building according to one embodiment of the present disclosure includes: <1> from <11> The present invention includes a column and a beam formed by a structural member according to any one of the above embodiments, and a web material having a larger area than the web material arranged on the column or the beam is arranged at the boundary between the column and the beam.

[0079] The present disclosure also includes a column and a beam formed by the structural member, and a web material having a larger area than the web material disposed on the column or beam is disposed at the boundary between the column and the beam. This allows the column and the beam to be connected more reliably in the building, making it easier to ensure the strength of the building. [Explanation of symbols]
