Japanese Unexamined Patent Publication No. 2017-043911

It is an object of the present invention to provide a building provided with a skeleton reinforcing member and a skeleton reinforcing member that enhances the certainty of reinforcement for the skeleton.

One aspect of the present invention is a skeleton reinforcing member including a main body portion that is fastened to a rail in a skeleton using rails for tracks via a fastening member. The body portion includes flange contact portions that make internal contact with both of the pair of flanges formed on both sides of the web in the height direction of the rail. The flange contact portion is connected to the web facing surface facing the web at a distance and the pair of flange facing surfaces facing the pair of tapered surfaces formed inside the pair of flanges. And an insertion hole formed to penetrate the web facing surface for inserting the fastening member. Assuming that the slope with respect to the first direction along the width direction of the web is the slope, the slope of one flange facing surface is different from the slope of one tapered surface facing one flange facing surface.

In the above-mentioned reinforcing member for the skeleton, since the gradient of one of the pair of flange facing surfaces is different from the gradient of the opposing tapered surfaces, the flange contact portion is not brought into contact with the web and is inside with respect to both flanges. Easy to contact from. Therefore, the stress acting on the flange of the rail due to the external force acting on the skeleton can be easily transmitted between the insides of both flanges via the flange contact portion. That is, apart from the web, it is easy to form a stress transfer path connecting the insides of both flanges. Therefore, it is possible to increase the certainty of reinforcement for the skeleton.

The slope of the other flange facing surface is preferably different from the slope of the other tapered surface facing the other flange facing surface. By making the gradients of both flange facing surfaces different from the gradients of the tapered surfaces facing each other, it is easier to form a stress transfer path connecting the insides of both flanges.

The width of one flange on which one tapered surface is formed is narrower than the width of the other flange on which the other tapered surface is formed, and the gradient of one flange facing surface is steeper than the gradient of one tapered surface. It is a gradient, and the gradient of the other flange facing surface is preferably a gentler gradient than the gradient of the other tapered surface. By making the flange facing surface facing the tapered surface of the narrow flange steeper than this tapered surface, it is easy to bring the flange contact part into contact with the end side of the narrow flange, so the flange contact part and the web Contact can be further suppressed. Further, by making the flange facing surface facing the tapered surface of the wide flange a gentler slope than this tapered surface, it is easy to prevent the flange contact portion from coming into contact with the end side of the wide flange, so that the main body portion It is possible to suppress the deformation of the flange due to the fastening to the rail.

The flange contact portion preferably contacts the other tapered surface closer to the web. By bringing the flange contact portion into contact with the position closer to the web on the tapered surface of the wide flange, the deformation of the wide flange can be further suppressed.

The main body portion preferably includes a flange portion facing in the first direction with respect to one flange. By facing the flange portion of the main body portion in the first direction with respect to one flange, the cross-sectional area of the main body portion can be expanded along the height direction of the web. Therefore, the bending rigidity of the main body can be increased.

The body portion preferably includes a flange portion that faces the other flange in the first direction. By facing the flange portion of the main body portion in the first direction with respect to the other flange, the cross-sectional area of the main body portion can be expanded along the height direction of the web. Therefore, the bending rigidity of the main body can be increased.

It is preferable to include a pair of main body portions that sandwich the web from both sides in the first direction, and the pair of main body portions are integrally fastened via a fastening member. It is easy to form stress transfer paths connecting the insides of both flanges on both sides of the web in the first direction. Therefore, it is possible to further increase the certainty of reinforcement for the skeleton while suppressing the load on the web.

Another aspect of the present invention is a building including the above-mentioned skeleton reinforcing member and a skeleton to which the skeleton reinforcing member is attached. By using the above-mentioned reinforcing member for the skeleton, the certainty of reinforcement for the skeleton can be enhanced. Therefore, it is possible to provide a strong structure.

According to the present invention, it is possible to provide a building provided with a skeleton reinforcing member and a skeleton reinforcing member that enhances the certainty of reinforcement for the skeleton.

Hereinafter, embodiments of a building including the skeleton reinforcing member and the skeleton reinforcing member disclosed in the present application will be described in detail with reference to the accompanying drawings. The present invention is not limited to the embodiments shown below.

Further, in the embodiments shown below, expressions such as "symmetrical", "parallel", "vertical" or "same" are used, but they are strictly "symmetrical", "parallel", "vertical" or "same". Does not need. That is, each of the above expressions allows for deviations in manufacturing accuracy, installation accuracy, and the like.

First, the building 1 provided with the skeleton 200 to which the skeleton reinforcing member 5 according to the embodiment is attached will be described with reference to FIG. FIG. 1 is a schematic perspective view of the building 1. Note that FIG. 1 exemplifies a building (passenger upper house) 1 built in a passenger home on a railroad, but does not limit the construction location of the building 1. That is, the building 1 can be built in any place where a general building is built.

As shown in FIG. 1, the building 1 includes a skeleton 200 including a rail 100 for a track that is fixed by being embedded in a floor body 500, and a roof body 600 supported by the skeleton 200. An example of the skeleton 200 includes a rail 100 in a column or a beam. Although FIG. 1 shows a rail 100 that bends in the middle, the rail 100 may be linear. Further, the skeleton 200 may include a linear rail and a rail 100 that bends in the middle.

As shown in FIG. 1, the rail 100 included in the skeleton 200 is reinforced by the skeleton reinforcing member 5. Although one skeleton reinforcing member 5 is shown in FIG. 1 from the viewpoint of simplifying the explanation, the rail 100 may be reinforced by an arbitrary number of skeleton reinforcing members 5. Further, although FIG. 1 shows a case where the skeleton reinforcing member 5 is attached to the straight portion of the rail 100, the skeleton reinforcing member 5 may be attached to the bent portion. Further, the skeleton reinforcing member 5 may be attached to the connection portion of the plurality of rails 100.

In this way, by attaching the skeleton reinforcing member 5 to an arbitrary position on the rail 100, it is possible to selectively reinforce a damaged portion such as a crack, or to specify a base end portion or a bent portion of the rail 100. It is possible to reinforce the part of. Further, the rail 100 can be totally reinforced by arranging a plurality of skeleton reinforcing members 5 side by side.

The skeleton reinforcing member 5 has a shape that easily forms a stress transmission path for transmitting stress acting on the rail 100 due to an external force acting on the skeleton 200, and enhances the certainty of reinforcement for the skeleton 200. A strong structure 1 can be provided, but details of such a shape will be described later with reference to FIG. 4 and the like.

Next, the skeleton reinforcing member 5 will be described in detail with reference to FIG. 2 and the like. FIG. 2 is a perspective view of the rail 100 reinforced by the skeleton reinforcing member 5. Here, FIG. 2 shows a three-dimensional Cartesian coordinate system of the X axis along the height direction of the web 101 in the rail 100, the Y axis along the width direction of the web 101, and the Z axis along the extension direction of the web 101. ing.

In the following, the above-mentioned height direction will be referred to as "height direction X", the above-mentioned width direction will be referred to as "width direction Y", and the above-mentioned stretching direction will be referred to as "stretching direction Z". Further, the Cartesian coordinate system shown in FIG. 2 may be shown in other drawings.

As shown in FIG. 2, the rail 100 includes a web 101 and a pair of flanges 102 and 103 formed on both sides of the web 101 in the height direction X. Here, one flange 102 is narrower than the other flange 103. In addition, as an example of the rail 100, a wheel of a train or the like rolls on a narrow flange 102, and a wide flange 103 is fixed to the ground side, and the old rail for a track is reused.

As shown in FIG. 2, the skeleton reinforcing member 5 has a pair of main body portions 10 sandwiching the web 101 from both sides of the first direction D along the width direction Y of the web 101, and the main body portions 10 are fastened to the rail 100. A fastener 110 to be used is provided. The main body portion 10 includes a flange contact portion 11 that comes into contact with both of the pair of flanges 102 and 103 from the inside. Further, the pair of main body portions 10 are integrally fastened to the web 101 via the fastener 110.

Therefore, the skeleton reinforcing member 5 tends to form stress transmission paths connecting the insides of both flanges 102 and 103 on both sides of the first direction D in the web 101. That is, it is possible to further increase the certainty of reinforcement for the skeleton 200 (see FIG. 1) while suppressing the load on the web 101. Although FIG. 2 shows a case where the four fasteners 110 are provided along the stretching direction Z, the number of fasteners 110 can be any number.

Further, as shown in FIG. 2, the main body portion 10 includes a flange portion 12 and a flange portion 13 facing the flange 102 and the flange 103 in the first direction D, respectively. That is, the flange portion 12 is arranged so as to sandwich the flange 102 from both sides in the first direction D, and the flange portion 13 is arranged so as to sandwich the flange 103 from both sides in the first direction D. It should be noted that at least one of the flange portion 12 and the flange portion 13 may be omitted.

Here, since the pair of main body portions 10 of the reinforcing member 5 for the skeleton are made of cast iron manufactured by pouring molten iron, alloy, or other metal into a mold, they have a high degree of freedom in shape and are integrally molded by casting. Is possible. Therefore, it can be widely used for rails 100 having different shapes.

Next, a case where the skeleton reinforcing member 5 shown in FIG. 2 is viewed from a direction different from that in FIG. 2 will be described with reference to FIG. FIG. 3 is a side view of FIG. 2 in the direction III direction.

As shown in FIG. 3, the main body 10 is fastened to the rail 100 by fasteners 110a to 110d, which are four fasteners 110. Further, the main body portion 10 includes a flange contact portion 11 that comes into contact with both of the pair of flanges 102 and 103 from the inside.

Note that FIG. 3 shows a case where the distance between the fastener 110a and the fastener 110b is the same as the distance between the fastener 110c and the fastener 110d, and both distances are larger than the distance between the fastener 110b and the fastener 110c. However, the distance between both or one of them may be equal to or smaller than the distance between the fastener 110b and the fastener 110c. Further, the distances between the adjacent fasteners 110 may all be the same.

Next, the cross-sectional shape of the skeleton reinforcing member 5 will be described with reference to FIG. FIG. 4 is a cross-sectional view taken along the line IV-IV of FIG. Note that FIG. 4 shows the cross-sectional shape of the rail 100 together with the cross-sectional shape of the skeleton reinforcing member 5. Further, FIG. 4 shows a main body portion 10A and a main body portion 10B which are a pair of main body portions 10 sandwiching the web 101 of the rail 100 from both sides in the first direction D. Further, a fastener 110 for integrally fastening the main body portion 10A and the main body portion 10B to the rail 100 is shown.

Further, in FIG. 4, for simplification of the explanation, two first directions D2 and D3 are shown as the first direction D (see FIG. 2), but these point to the same direction. .. The description of the double-headed arrow in the first direction D shown in FIG. 2 is omitted. Further, in the following, when distinguishing the gradient α which is the inclination with respect to the first direction D, the gradient α1 and the gradient α2 are described.

Note that FIG. 4 shows the symmetry line SP of the rail 100 in the XY plane parallel to the height direction X and the width direction Y for reference. The web 101 is provided with a through hole 101h that penetrates the web 101 in the width direction Y. The center line VP of the through hole 101h is shown for reference. Further, although FIG. 4 shows a case where the symmetry line SP and the center line VP are vertical, it is not necessary to make them vertical. That is, the center line VP may be tilted on a plane parallel to the XY plane or tilted on a plane parallel to the YZ plane.

The main body 10A and the main body 10B shown in FIG. 4 have opposite mounting directions with respect to the symmetric line SP, but have the same shape. Therefore, the shape of the main body 10A will be described below. And.

The main body portion 10A includes a flange contact portion 11 that comes into contact with both the flange 102 and the flange 103 from the inside. The flange contact portion 11 includes a web facing surface 11a facing the web 101 at a distance.

Further, the flange contact portion 11 faces the flange facing surface 11b facing the one tapered surface 102b formed inside one flange 102 and the other tapered surface 103c formed inside the other flange 103. Includes a flange facing surface 11c. The flange facing surfaces 11b and 11c are formed so as to be connected to the web facing surface 11a.

The portion where the web facing surface 11a and the flange facing surface 11b are continuous may be square or R-shaped. The same applies to the portion where the web facing surface 11a and the flange facing surface 11c are continuous.

Further, the flange contact portion 11 includes an insertion hole 11h formed so as to penetrate the web facing surface 11a for inserting the bolt (fastening member) 111 of the fastener 110. The insertion hole 11h is formed so as to penetrate the flange contact portion 11 in the first direction D. The fastener 110 includes a bolt (fastener) 111, a nut 112, and a washer 113.

The bolt 111 is inserted into the insertion holes 11h of the pair of main body portions 10A and 10B and the through holes 101h of the rail 100 sandwiched between the pair of main body portions 10A and 10B. The pair of main body portions 10A and 10B and the rail 100 are integrally fastened to the bolt 111 on the opposite side of the head of the bolt 111 by a nut 112 attached to the bolt 111 with the washer 113 interposed therebetween. In this example, the case where a Torsia type high-strength bolt is used as the fastening member 111 is shown, but a hexagonal high-strength bolt or the like may be used. The same applies to the following.

Here, assuming that the inclination of the web 101 with respect to the first direction D along the width direction Y is the gradient α, the gradient α of one of the flange facing surfaces 11b and 11c is one (flange facing surface 11b or flange facing surface 11c). Is different from the gradient α of the tapered surface 102b or the tapered surface 103c facing each other.

With such a gradient α, the flange contact portion 11 can be easily brought into contact with both flanges 102 and 103 in the height direction X from the inside without contacting the web 101. Therefore, the stress acting on the flanges 102 and 103 of the rail 100 due to the external force acting on the skeleton 200 (see FIG. 1) is transmitted between the insides of both flanges 102 and 103 via the flange contact portion 11. Cheap. That is, apart from the web 101, it is easy to form a stress transfer path connecting the insides of both flanges 102 and 103. Therefore, it is possible to increase the certainty of reinforcement for the skeleton 200.

Further, in FIG. 4, the gradient α of the flange facing surfaces 11b and 11c is different from the gradient α of the tapered surfaces 102b and 103c on which the flange facing surfaces 11b and 11c face each other. In this way, by making the gradient α of both flange facing surfaces 11b and 11c different from the gradient α of the tapered surfaces 102b and 103c facing each other, a stress transmission path connecting the insides of both flanges 102 and 103 can be created. It is easier to form.

Further, in FIG. 4, the gradient α1 of the flange facing surface 11b is steeper than the gradient α2 of the tapered surface 102b, and the gradient α3 of the flange facing surface 11c is a gentler gradient than the gradient α4 of the tapered surface 103c. That is, "gradient α1> gradient α2" and "gradient α3 <gradient α4".

By making the flange facing surface 11b steeper than the tapered surface 102b in this way, it is easy to bring the flange contact portion 11 into contact with the end portion side of the narrow flange 102. Therefore, the contact between the flange contact portion 11 and the web 101 can be suppressed.

Further, by making the flange facing surface 11c a gentler slope than the tapered surface 103c, it is easy to prevent the flange contact portion 11 from coming into contact with the end portion side of the wide flange 103. Therefore, it is possible to suppress the deformation of the flange 103 due to the fastening of the main body portion 10A to the rail 100.

Further, as shown in FIG. 4, the flange contact portion 11 comes into contact with the tapered surface 103c of the wide flange 103 toward the web 101. By setting the contact position P3 closer to the web 101 in this way, deformation of the wide flange 103 can be further suppressed.

In this example, by making the flange facing surface 11b steeper than the tapered surface 102b, the flange facing surface 11b can be brought into contact with the corner portion formed at the end of the flange 102. Therefore, when the main body 10 is fastened to the web 101 by the fastener 110, even if the pair of main bodies 10 are attracted to each other in the first direction D, the contact between the web facing surface 11a and the web 101 Can be suppressed.

Further, in this example, by making the flange facing surface 11c a gentler slope than the tapered surface 103c, the end portion of the flange facing surface 11c (the connection portion with the web facing surface 11a) is a portion excluding the end portion of the tapered surface 103c. Can be contacted with. Therefore, it is possible to suppress the deformation of the flange 103 and the contact between the web facing surface 11a and the web 101.

Further, as shown in FIG. 4, the web facing surface 11a is formed in a flat shape without protrusions or the like. Therefore, when the main body 10 is fastened to the web 101 by the fastener 110, the two flange facing surfaces 11b (or 11c) and the web facing surface 11a are fastened in contact with the rail 100. Can be suppressed. Therefore, the pair of flange facing surfaces 11b and 11c can be securely fastened to the pair of tapered surfaces 102b and 103c in a state of being in contact with each other, and the certainty of reinforcement can be improved.

Note that FIG. 4 shows a case where the contact position P3 between the flange facing surface 11c and the flange 103 is closer to the web 101 than the contact position P2 between the flange facing surface 11b and the flange 102, but the opposite positional relationship is shown. Or may have the same positional relationship.

Further, FIG. 4 shows a case where the gradient α1 of the flange facing surface 11b is different from the gradient α2 of the tapered surface 102b and the gradient α3 of the flange facing surface 11c is different from the gradient α4 of the tapered surface 103c. One of the gradients α of the facing surfaces 11b and 11c may be equal to the gradient α of the tapered surfaces 102b and 103c facing the flange facing surfaces 11b and 11c. The variation of the gradient α in the flange contact portion 11 will be described later with reference to FIGS. 8 and 8.

Further, as already described with reference to FIG. 2, the main body portion 10A has a flange portion 12 facing the flange 102 in the first direction D and a flange facing the flange 103 in the first direction D. Including part 13. As described above, at least one of the flange portion 12 and the flange portion 13 may be omitted.

By providing the flange portion 12 facing the narrow flange 102 in the main body portion 10, the cross-sectional area of the main body portion 10 can be expanded along the height direction X of the web 101. Therefore, the bending rigidity of the main body 10 can be increased.

Further, by providing the flange portion 13 facing the wide flange 103 in the main body portion 10, the cross-sectional area of the main body portion 10 can be expanded along the height direction X of the web 101. Therefore, the bending rigidity of the main body 10 can be further increased.

Since the flange 102 facing the flange portion 12 is narrower than the flange 103 facing the flange portion 13, the flange portion 12 is easier to secure the cross-sectional area in the width direction Y than the flange portion 13. Therefore, when one of the flange portions 12 and 13 is omitted, the bending rigidity of the main body portion 10 can be relatively increased by omitting the flange portion 13.

As shown in FIG. 4, the flange portion 12 faces the narrow flange 102 in the first direction D and is within the range of the thickness (dimension) of the flange 102 in the height direction X. It is formed. Further, the flange portion 13 is formed so as to face the wide flange 103 in the first direction D and to be within the range of the thickness (dimension) of the flange 103 in the height direction X. Therefore, the flange portions 12 and 13 do not protrude in the height direction X with respect to the rail 100. Therefore, even if other structures or the like are installed on both sides or one side of the rail 100 in the height direction X, the skeleton reinforcing member 5 is attached to the rail 100 without interfering with the other structures or the like. On the other hand, it can be easily attached and the rail 100 can be efficiently reinforced.

Further, the main body portion 10A is provided on the back surface side (the side opposite to the web 101) of the flange contact portion 11 with the flange contact portion 11 and the flange portions 12 and 13 provided on both sides of the flange contact portion 11 in the height direction X. Includes a recess 15 formed so as to be surrounded by. By forming the recess 15 in this way, the main body portion 10A can be made thin, and the weight of the main body portion 10A can be reduced. Further, the design can be improved by accommodating the fastener 110 in the recess 15.

Although FIG. 4 shows a case where the bolt 111 protrudes from the recess 15, the length of the bolt 111 may be set to the length accommodated in the recess 15. By adjusting the length of the bolt 111 in this way, the skeleton reinforcing member 5 can be made more compact.

Further, although FIG. 4 shows a case where the bolt 111 is inserted from the main body portion 10B side, it may be inserted from the main body portion 10A side. Further, although FIG. 4 shows a case where a pair of main body portions 10A and 10B are used, the main body portion 10A or the main body portion 10B may be omitted. When one side of the first direction D of the rail 100 is a narrow portion or the like and the web 101 cannot be sandwiched by the pair of main body portions 10A and 10B, one of the main body portions 10A (or 10B) is used. Can be used to reinforce the rail 100. In this case, a one-side bolt or the like may be used as the bolt 111 to insert the bolt into the through hole 101h of the rail 100 for fastening.

Next, the perspective view shown in FIG. 2 will be described in more detail with reference to FIGS. 5, 6 and 7. FIG. 5 is an exploded perspective view of the skeleton reinforcing member 5 shown in FIG. 2. 6 is a side view of FIG. 2 in the VI direction view, and FIG. 7 is a side view of FIG. 2 in the VII direction view.

As shown in FIG. 5, the main body portion 10A is attached to the rail 100 from the negative direction side of the Y axis, and the main body portion 10B is attached to the rail 100 from the positive direction side of the Y axis. In the main body portions 10A and 10B, the bolt 111 is inserted into the insertion hole 11h and the through hole 101h while aligning the insertion hole 11h and the through hole 101h of the web 101, respectively.

Then, the washer 113 is attached to the tip end side of the bolt 111, and then the nut 112 is attached. As a result, the pair of main body portions 10A and 10B are first in contact with each other in the height direction X from the inside with respect to both flanges 102 and 103 without the flange contact portions 11 contacting the web 101. It is tightened in the direction D of and fixed to the rail 100. In the case shown in FIG. 5, the skeleton reinforcing member 5 is fixed to the rail 100 by fastening the four sets of bolts 111 and nuts 112, respectively.

As shown in FIG. 6, when the rail 100 is viewed from the wide flange 103 side, the flange portions 13 of the main body portions 10A and 10B are arranged on both sides of the flange 103 in the width direction Y, respectively. Further, as shown in FIG. 7, when the rail 100 is viewed from the narrow flange 102 side, the flange portions 12 of the main body portions 10A and 10B are arranged on both sides of the flange 102 in the width direction Y, respectively.

Next, variations of the main body 10 shown in FIGS. 4 and the like will be described with reference to FIGS. 8 to 12. 8 to 12 are explanatory views showing variations 1 to 5 of the main body 10. In addition, in FIGS. 8 to 12, one of the two main body portions 10 shown in FIG. 4 is shown.

Further, in FIGS. 8 to 12, the description of the insertion hole 11h, the through hole 101h and the fastener 110 shown in FIG. 4 and the hatching showing the cross section is omitted. Further, in the following, the main body 10 of the variations 1 to 5 will be described as the main body 10a, the main body 10b, the main body 10c, the main body 10d, and the main body 10e, respectively.

As shown in FIG. 8, in the main body portion 10a, which is the first variation of the main body portion 10, the gradient α1 of the flange facing surface 11b is steeper than the gradient α2 of the tapered surface 102b facing the flange facing surface 11b. Further, the gradient α3 of the flange facing surface 11c is the same as the gradient α4 of the tapered surface 103c facing the flange facing surface 11c. That is, "gradient α1> gradient α2" and "gradient α3 = gradient α4". As described above, in the main body portion 10a, the gradient α1 of one flange facing surface 11b is different from the gradient α2 of one tapered surface 102b.

By making the flange facing surface 11b steeper than the tapered surface 102b in this way, the flange facing surface 11b can be brought into contact with the corner portion formed at the end of the flange 102. Therefore, the contact between the web facing surface 11a and the web 101 can be suppressed.

Further, by making the flange facing surface 11c have the same gradient as the tapered surface 103c, the contact area between the flange facing surface 11c and the tapered surface 103c can be increased. Therefore, the stress associated with the fastening of the main body portion 10a to the rail 100 can be dispersed, and the deformation of the flange 103 can be suppressed. Further, the relative posture between the main body portion 10a and the rail 100 can be stabilized.

As shown in FIG. 9, in the main body portion 10b, which is the second variation of the main body portion 10, the gradient α1 of the flange facing surface 11b has a gentler gradient than the gradient α2 of the tapered surface 102b facing the flange facing surface 11b. Further, the gradient α3 of the flange facing surface 11c is the same as the gradient α4 of the tapered surface 103c facing the flange facing surface 11c. That is, "gradient α1 <gradient α2" and "gradient α3 = gradient α4". As described above, in the main body portion 10b, the gradient α1 of one flange facing surface 11b is different from the gradient α2 of one tapered surface 102b. Although FIG. 9 shows a case where the gradient α1 is parallel to the first direction D2, that is, “gradient α1 = 0”, the gradient α1 may be an angle other than 0.

Further, the gradient α3 of the flange facing surface 11c is steeper than the gradient α4 of the tapered surface 103c facing the flange facing surface 11c. That is, "gradient α1 = gradient α2" and "gradient α3> gradient α4". As described above, in the main body portion 10d, the gradient α3 of one flange facing surface 11c is different from the gradient α4 of one tapered surface 103c.

By making the flange facing surface 11b have the same gradient as the tapered surface 102b in this way, the contact area between the flange facing surface 11b and the tapered surface 102b can be increased. Therefore, the stress associated with the fastening of the main body portion 10d to the rail 100 can be dispersed, and the deformation of the flange 102 can be suppressed. Further, the relative posture between the main body portion 10d and the rail 100 can be stabilized.

Further, by making the flange facing surface 11c steeper than the tapered surface 103c, the flange facing surface 11c can be brought into contact with the corner portion formed at the end portion of the flange 103. Therefore, contact between the web facing surface 11a and the web 101 can be suppressed.

As shown in FIG. 12, in the main body portion 10e, which is the fifth variation of the main body portion 10, the gradient α1 of the flange facing surface 11b has a gentler gradient than the gradient α2 of the tapered surface 102b facing the flange facing surface 11b. Further, the gradient α3 of the flange facing surface 11c has a gentler gradient than the gradient α4 of the tapered surface 103c facing the flange facing surface 11c. That is, "gradient α1 <gradient α2" and "gradient α3 <gradient α4". As described above, in the main body portion 10e, the gradient α1 of one flange facing surface 11b is different from the gradient α2 of one tapered surface 102b, and the gradient α3 of the other flange facing surface 11c is the other tapered surface 103c. It is different from the gradient α4. Although FIG. 12 shows a case where the gradient α1 is parallel to the first direction D2, that is, “gradient α1 = 0”, the gradient α1 may be an angle other than 0.

In this way, by making the flange facing surface 11b a gentler slope than the tapered surface 102b, the end portion of the flange facing surface 11b (the connection portion with the web facing surface 11a) is set with respect to the portion excluding the end portion of the tapered surface 102b. Can be contacted. Therefore, it is possible to suppress the deformation of the flange 102 and the contact between the web facing surface 11a and the web 101.

As described above, the variations of the main body portion 10 in the skeleton reinforcing member 5 have been described with reference to FIGS. 8 to 12, but these variations are only a part of many variations. That is, in the main body 10, the gradient of at least one flange facing surface may be different from the gradient of the one tapered surface facing which one flange facing surface faces.

In the above-described embodiment, the skeleton reinforcing member 5 that sandwiches the web 101 between the pair of main body portions 10 is shown, but one main body portion 10 is integrally fastened to the web 101 with a fastener 110 to the web 101. It may be that. In this case, the bolt (fastening member) 111 may fasten the main body 10 to the web 101 via the through hole 101h penetrating the web 101, or instead of the through hole 101h, a screw that does not penetrate the web 101. The main body 10 may be fastened to the web 101 through the holes.
