(A) is a figure which shows the reinforcement structure 20b, (b) is the G section enlarged view of (a). The figure which shows the reinforcement structure 20c.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is an exploded perspective view showing the fixing member 1, FIG. 2 is an assembled perspective view showing the fixing member 1, and FIG. 3 is a cross-sectional view of the fixing member 1 taken along a line AA in FIG. is there.

  The fixing member 1 mainly includes a holding member 3a as a first holding member, a holding member 3b as a second holding member, a bolt 5 and a nut 7 as joining members, and the like. The fixing member 1 is a member for attaching a reinforcing member to an angle iron or the like. The material of the holding members 3a and 3b is not particularly limited, but is, for example, steel.

  As shown in FIG. 3, the one holding member 3 a has a mountain-like portion 4 formed substantially at the center in the length direction of the fixing member 1 (the left-right direction in FIG. 3). The mountain-shaped part 4 is a part whose height is higher than other parts. Both sides of the mountain-shaped portion 4 with respect to the length direction of the fixing member 1 project in a plate shape, and a holding portion 6a is formed outside the mountain-shaped portion 4, and a joining portion 8a is formed further outside the holding portion 6a. You.

  The side surfaces of the mountain-shaped portion 4 and the upper surfaces of the holding portion 6a and the joining portion 8a that protrude in a plate shape are connected by ribs 11 and reinforced. The ribs 11 have a substantially triangular plate shape, and are formed near both ends in the width direction (perpendicular to the longitudinal direction and perpendicular to the plane of FIG. 3) of the holding member 3a. The holding member 3a may be formed by joining plate-like ribs 11 by welding or the like, or may be formed integrally as a whole.

  For example, when the rib 11 is formed integrally, the form of the rib 11 does not have to be plate-like as in the fixing member 1e shown in FIG. In the fixing member 1e, the ribs 11 are formed so that the height gradually decreases and the width increases from substantially the center in the width direction of the mountain-shaped portion 4 toward the holding portion 6a and the joining portion 8a. A part of the rib 11 is cut out on the upper surface of the joint 8a to avoid interference with the nut 7 and the like. As described above, when the holding member 3a is integrally formed by casting or the like, a form like the fixing member 1e may be used. In addition, the form of the rib 11 and the mountain-shaped portion 4 is not limited to the illustrated example and is not particularly limited.

  A notch 9 is provided in the mountain-shaped portion 4 of the holding member 3a on the side facing the holding member 3b described later. The notch 9 is formed over the entire width of the holding member 3a. The notch 9 is a part for avoiding interference with an angle iron or the like. In the present embodiment, as shown in FIG. 3, a plurality of angle irons 21 are arranged in a substantially T shape (an inverted T shape in the figure). Therefore, the notch 9 is formed in a substantially T shape so as to avoid interference with the angle iron 21.

  Holes 15a are respectively formed in the joining portions 8a formed on both sides of the cutout portion 9 of the holding member 3a and outside the holding portions 6a and 6b. The hole 15a is a joint with the other holding member 3b.

  The holding member 3b is a plate-shaped member, and is disposed so as to face the holding member 3a. In the holding member 3b, a portion of the holding member 3a facing the holding portion 6a is the holding portion 6b, and a portion of the holding member 3a facing the joining portion 8a is the joining portion 8b.

  When the holding member 3b is arranged to face the holding member 3a, a hole 15b is formed in the joint 8b corresponding to the hole 15a of the joint 8a. Bolts 5 are inserted into the holes 15a and 15b, and are joined by nuts 7. That is, the holding member 3 a and the holding member 3 b are joined by the bolts 5 and the nuts 7 as joining members on both sides of the notch 9. By doing so, as shown in FIG. 3, it is possible to sandwich a part of the angle iron 21 between the holding portion 6a of the holding member 3a and the holding portion 6b of the holding member 3b. The joining member need not be the bolt 5 and the nut 7, and the nut 7 may be integral with the holding member, or a female screw portion may be formed in the hole 15a or the hole 15b.

  The portions of the holding portion 6b and the joining portion 8b of the holding member 3b are slightly thinner than the portions on both sides in the length direction. Therefore, steps 17 are formed on both sides in the length direction of the joining portion 8b of the holding member 3b so as to increase the thickness. Each step 17 is formed along the width direction of the holding member 3b. That is, the holding member 3a is disposed between the steps 17 on both sides of the holding member 3b.

  A connecting portion 13 extending in a direction protruding from the holding member 3a is formed further outside the one joining portion 8b of the holding member 3b. For example, a hole is provided in the connecting portion 13 so that a reinforcing member can be attached.

  The connecting portion 13 may be formed not on the holding member 3b but on the holding member 3a side. That is, the connecting portion 13 is provided on at least one of the holding member 3a and the holding member 3b. Further, the connecting portion 13 may be formed not to extend in the length direction of the fixing member 1 but to extend in the width direction. Further, the connecting portion 13 may be formed in the height direction of the fixing member 1 (the vertical direction in FIG. 3 and above the holding member 3a or below the holding member 3b). Further, the connecting portion 13 does not necessarily have to project in a plate shape, and a hole may be directly formed at any position of the holding members 3a and 3b.

  Next, an example of a reinforcing structure using the fixing member 1 will be described. FIG. 5 is a diagram showing a reinforcing structure 20 using the fixing member 1, FIG. 6 is an enlarged perspective view of a portion B in FIG. 5, and FIG. 7 is a cross-sectional view taken along line CC in FIG.

  The reinforcement object 23 in the reinforcement structure 20 is constituted by structures 23a and 23b that are substantially orthogonal to each other. The structures 23 a and 23 b are formed by the angle iron 21. In the present embodiment, in a part of the structures 23a and 23b, a pair of angle irons 21 are arranged back to back, and as a whole, arranged in a substantially T-shape. The angle iron 21 of the structure 23b is sandwiched between the holding members 3a and 3b, and the fixing member 1 is fixed to the structure 23b.

  One fixing member 1 is fixed to one structure 23b, and the other fixing member 1 is fixed to the other structure 23b. That is, the fixing member 1 is fixed to each of the angle irons 21 that are spaced apart. The ends of the braces 45 are attached to the connecting portions 13 of the pair of fixing members 1 by pins 37, respectively. That is, the brace 45 as a reinforcing member is attached so as to connect the connecting portions 13 of the respective fixing members 1. The brace 45 is, for example, a wire or a bar, and a turn buckle (not shown) or the like is used for the brace 45.

  FIG. 8 is an enlarged view of a portion D in FIG. As described above, a part of the angle iron 21 is sandwiched between the holding portion 6a of the holding member 3a and the holding portion 6b of the holding member 3b. At this time, a slight gap 35 is formed between the joint 8a of the sandwiching member 3a and the joint 8b of the sandwiching member 3b. By doing so, the angle steel 21 can be reliably sandwiched between the clamping portions 6a and 6b.

  Except for the holding portions 6a and 6b in which the angle iron 21 is sandwiched, the notch 9 is formed sufficiently large with respect to the angle iron 21. That is, a gap may be formed between the angle iron 21 and the holding members 3a and 3b except for the holding portions 6a and 6b. In this way, the fixing member 1 of one size can be applied to the angle irons 21 of a plurality of sizes.

  As described above, according to the present embodiment, since the notch 9 corresponding to the shape of the angle iron 21 is provided, there is no interference between the angle iron 21 and the fixing member 1, and the angle iron 21 is held by the pair of holding members 3a, 3b. Can be pinched. For this reason, the fixing member 1 can be fixed to the reinforcing object 23 without performing drilling or the like on the angle iron 21. Further, the fixing member 1 can be easily attached to the existing reinforcing object 23.

  Further, since the steps 17 are provided on both sides of the holding member 3a, it is possible to prevent the holding member 3a from being displaced from the holding member 3b when a force in the length direction is applied to the holding member 3b. Further, since the force applied to the holding member 3b can be transmitted to the holding member 3a via the step 17, the force from the reinforcing member can be more reliably transmitted to the reinforcement target 23. In order to engage the holding members 3a and 3b at the step 17, the height of the step 17 is desirably higher than the gap 35 between the joints 8a and 8b.

  In addition, by increasing the size of the notch 9 with respect to the angle iron 21, it is possible to cope with the angle iron 21 having a plurality of sizes.

  As described above, in the reinforcing structure 20, the pair of fixing members 1 are fixed to the angle irons 21 that are spaced apart from each other and constitute the reinforcing object 23, and each fixing member 1 is a brace that is a reinforcing member. It is connected at 45. As shown in FIG. 5, in the present embodiment, an example is shown in which the fixing member 1 is disposed only on the structure 23b that is separated from the other, but the fixing member 1 is fixed on both of the structures 23a and 23b. A brace 45 may be provided so as to connect the two. Further, in the present embodiment, an example is shown in which the pair of braces 45 are arranged in a substantially X shape, but the arrangement and orientation of the brace 45 such as a V shape, an inverted V shape, and a K shape are shown in the illustrated example. Not limited to

  In the present embodiment, the brace 45 is shown as the reinforcing member. However, instead of the brace 45, a brace using a channel steel or the like may be used. That is, for the angle irons 21 arranged in directions substantially orthogonal to each other, by arranging the diagonal members obliquely as a reinforcing member so as to connect them, the reinforcing object 23 can be efficiently reinforced. . In the following description, an example of the brace 45 will be described as an oblique material.

  Further, in the present embodiment, the case where the angle irons 21 are arranged in a substantially T-shape has been described, but the arrangement of the angle irons 21 is not limited to this. FIG. 9A is a diagram illustrating an example using the fixing member 1a.

  The fixing member 1 a has substantially the same configuration as the fixing member 1, but differs in the form of the notch 9. In the following description, components having the same functions as those of the above-described embodiment will be denoted by the same reference numerals as those in FIGS. 1 to 8, and redundant description will be omitted. In the following drawings, illustration of a reinforcing member is omitted unless otherwise specified.

  When fixing to the L-shaped angle steel 21 as in a fixing member 1a shown in FIG. 9A, a substantially L-shaped notch 9 corresponding to this may be used. In this case, the holding portions 6a and 6b may be formed only on one side of the mountain-shaped portion 4.

  FIG. 9B is a diagram illustrating an example in which the fixing member 1b is used. The fixing member 1b has substantially the same configuration as the fixing member 1, but is different in the form of the holding member 3b. A ridge 4 is formed on the holding member 3b of the fixing member 1b in substantially the same manner as the holding member 3a.

  The holding members 3a and 3b have a substantially T-shaped notch 9 in each of the mountain-shaped portions 4 facing each other. That is, the notch 9 is provided in both the holding members 3a and 3b. When the notches 9 of the sandwiching members 3a and 3b are joined to face each other, the shape of the notches 9 becomes substantially a cross shape. In this manner, the fixing member 1b can correspond to a structure in which four L-shaped angle steels 21 are arranged back to back and arranged in a substantially cross shape.

  Note that there is no problem when the individual angle irons 21 are in back-to-back contact with each other, but at least when a gap is formed between the individual angle irons 21 as illustrated, at least Spacers 39 are arranged in the gaps between the angle irons 21 in the direction sandwiched by the sandwiching members 3a and 3b. By doing so, the plurality of angle irons 21 can be reliably sandwiched and fixed between the sandwiching members 3a and 3b.

  As described above, by designing the shape of the notch 9 or the like according to the shape of the angle iron 21, the structure can be fixed to any structure.

  Note that, in each of the above-described embodiments, the example in which the L-shaped angle irons 21 are arranged individually or in combination is shown, but the present invention is not limited to this. For example, a C-section steel or a T-section steel may be arranged alone or in combination. As described above, the present invention can be fixed to an object whose cross-sectional shape is not L-shaped. In this case, the shape of the notch 9 may be formed so as not to interfere with the angle iron or the like in accordance with the arrangement of the angle iron or the like. In the following description, the angle iron 21 will be described, but it can be replaced with a C-beam or a T-beam.

  Further, the fixing member does not have to be constituted by one holding member 3a and one holding member 3b. For example, one holding member 3b may be joined to three holding members 3a as in a fixing member 1c shown in FIG. That is, a plurality of holding members 3a are provided and joined to one holding member 3b. By doing so, mounting is easier than in the case where a plurality of fixing members 1 are provided side by side.

  Next, a second embodiment will be described. FIG. 11 is a front view showing the reinforcing structure 20a, and FIG. 12 is a sectional view taken along line EE of FIG. The reinforcing structure 20a has substantially the same structure as the reinforcing structure 20, except that the reinforcing member is not a diagonal member but a reinforcing beam 47.

  The fixing members 1d are attached to the structures 23b that are spaced apart from each other and arranged substantially in parallel so that the connecting portions 13 face each other. Note that, similarly to the fixing member 1c, the fixing member 1d is fixed with a plurality of holding members 3a provided side by side with respect to one holding member 3b. A reinforcing beam 47 is connected to the connecting portion 13 of the fixing member 1d by a bolt 33 and a nut 31. The reinforcing beams 47 are connected so as to connect the fixing members 1d respectively fixed to the angle irons 21 of the structure 23b.

  The reinforcing beam 47 is disposed so as to be substantially orthogonal to the structure 23b. The reinforcing beam 47 may be, for example, a channel steel or an angle steel.

  According to the second embodiment, the same effect as in the first embodiment can be obtained. The reinforcing beam 47 may be any as long as it connects structures that are spaced apart from each other and arranged substantially in parallel.

  Next, a third embodiment will be described. FIG. 13A is a partial front view showing the reinforcing structure 20b, and FIG. 13B is an enlarged view of a portion G in FIG. 13A. In the reinforcing structure 20b, a fixing member 1f is used. The fixing member 1f has substantially the same configuration as the fixing member 1d, but connection portions 13a and 13b are provided on both sides of the holding member 3b in opposite directions. That is, a plurality of connecting portions 13a and 13b are provided on the fixing member 1f.

  In the reinforcing structure 20b, the fixing member 1f is fixed to each of the structures 23b that are spaced apart and arranged substantially in parallel with each other. At this time, the connecting portions 13a of the respective fixing members 1f face each other, and the connecting portions 13b are arranged in opposite directions to both sides. The fixing member 1c is fixed to the structure 23a substantially orthogonal to the structure 23b.

  A reinforcing beam 47 is connected as a reinforcing member to one connecting portion 13a of the fixing member 1f. A brace 45 is connected as a reinforcing member to the other connecting portion 13b of the fixing member 1f. As described above, the reinforcing beams 47 connect the fixing members 1f respectively fixed to the angle irons 21 arranged substantially in parallel with each other. The brace 45, which is a diagonal member, is connected so as to connect the fixing members 1f and 1c fixed to the angle irons 21 substantially orthogonal to each other.

  According to the third embodiment, the same effects as those of the first embodiment can be obtained. In addition, by arranging the plurality of connecting portions 13a and 13b on one fixing member 1f, the plurality of reinforcing members can be connected to one fixing member 1f.

  In the illustrated example, the reinforcing beam 47 is connected to one connecting portion 13a of the fixing member 1f, and the brace 45 is connected to the other connecting portion 13b. However, the present invention is not limited to this. For example, the reinforcing beams 47 may be connected to both the connecting portions 13a and 13b, and the braces 45 may be connected to both the connecting portions 13a and 13b.

  Next, a fourth embodiment will be described. FIG. 14 is a plan view of a reinforcing structure 20c. The reinforcing structure 20c is substantially the same as the reinforcing structure 20b, except that the fixing members 1g and 1h are used in the reinforcing structure 20c.

  In the reinforcing structure 20c, the structures 23b are arranged at four positions so as to be substantially rectangular in plan view. The fixing members 1h are fixed to one adjacent structure 23b (two lower positions in the figure). Further, a fixing member 1g is fixed to the other adjacent structure 23b (the two upper positions in the drawing) facing the structure 23b to which the fixing member 1h is fixed.

  The fixing member 1h has substantially the same configuration as the fixing member 1f, but further includes a connecting portion 13c in addition to the connecting portions 13a and 13b. The connecting portion 13c is provided on the top of the mountain-shaped portion 4 of the holding member 3a. The connecting portion 13c is provided in a direction substantially orthogonal to the connecting portions 13a and 13b provided on the holding member 3b, respectively. That is, the connecting portions 13a, 13b, and 13c are provided at three locations in one fixing member 1h.

  The connecting portion 13a and the connecting portion 13c are provided on the fixing member 1g. In this way, it is possible to arrange the connecting portions at two or more locations in one arbitrary fixing member in arbitrary directions different from each other.

  Similar to the fixing member 1f of the reinforcing structure 20b, a reinforcing beam 47 is connected to the mutually facing connecting portions 13a of the fixing member 1h of the reinforcing structure 20c. A brace 45 is connected to the connecting portion 13b of the fixing member 1h, and is connected to a fixing member 1d (not shown) fixed to the structure 23a.

  Further, similarly to the fixing member 1f of the reinforcing structure 20b, the reinforcing beams 47 are also connected to the mutually connected connecting portions 13a of the fixing member 1g. Further, a reinforcing beam 47 is connected to the connecting portion 13c of the fixing member 1h and the connecting portion 13c of the fixing member 1g so as to connect them.

  According to the fourth embodiment, the same effects as in the third embodiment can be obtained. Further, as in the case of the fixing member 1g, the connecting portions 13a and 13c may be formed in directions orthogonal to each other, and as in the case of the fixing member 1h, the connecting portions 13a, 13b and 13c may be formed in three directions. It may be formed.

  The reinforcing beams 47 are connected to the connecting portions 13a and 13c of the fixing members 1h and 1g, and the braces 45 are connected to the connecting portions 13b of the fixing member 1h. However, the present invention is not limited to this. For example, the reinforcing beams 47 may be connected to the connecting portions 13a, 13b, and 13c, and the braces 45 may be connected to the connecting portions 13a, 13b, and 13c. In the fixing member 1h, a reinforcing beam may be connected to at least one connecting portion, and a diagonal member may be connected to at least one other connecting portion.
