Description

TECHNICAL FIELD The present invention relates to a reinforcement structure for an object to be reinforced, to which a reinforcement member for seismic reinforcement is attached, for example.

In recent years, as a countermeasure against large earthquakes, seismic reinforcement has been carried out on structures. For example, there is a method in which diagonal members (brace or brace) are provided obliquely to structures such as columns and beams, and a method in which reinforcing beams are provided so as to connect structures arranged parallel to each other.

For such structures, L-shaped angle steel, C-shaped steel, or T-shaped steel (hereinafter simply referred to as "angle steel, etc.") may be used. Angle irons and the like are used, for example, when they are used alone, or in combinations of a plurality of angle irons, etc., to form a shape such as a T shape or a cross shape.

When attaching a reinforcing member, etc. to an object to be reinforced using such an angle steel, there is a method of drilling holes in the angle steel, etc., and fixing the reinforcing member to the angle steel, etc. with bolts, etc. General (for example, Patent Documents 1 and 2)

JP 2013-19233 A Japanese Patent Application Laid-Open No. 2007-132011

However, drilling an angle steel or the like reduces the strength of the angle steel or the like, which is not desirable as a reinforcing structure. In addition, since it takes time to drill holes in angle steel, etc., there is a problem that the working time is long.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a reinforced structure for an object to be reinforced, which enables seismic reinforcement of a structure or the like without drilling holes. .

To achieve the above object, the present invention provides a reinforcing structure for an object to be reinforced, comprising: a structure having a plate-like portion ; and a reinforcing member connected to the fixing member, wherein at least the first holding member is located near both ends of the first holding member, respectively a first joint portion provided; and a first clamping portion disposed inside the first joint portion and protruding toward a surface facing the second clamping member; A space for avoiding interference with the structure is formed inside the clamping portion, and the second clamping member is provided at a portion corresponding to each of the first joint portion and the first clamping portion. 2 joint portions and a second holding portion, wherein the first joint portion and the second joint portion are joined by a joining member, and the plate-like portion of the structure is held by the first holding portion; and the second holding portion, and at least one of the first holding member and the second holding member is provided with a connection portion to which the reinforcing member is connected, and is spaced apart. In the reinforcing structure of the object to be reinforced, the fixing members are fixed to the respective structures, and the reinforcing member is attached so as to connect the connecting portions of the fixing members.
The second clamping portion protrudes in the direction of the first clamping member, and the first clamping portion and the second clamping portion extend over the widths of the first clamping member and the second clamping member, respectively. It may be formed separately in a plurality of directions.

In the fixing member, the connecting portions are provided at two or more locations, a plurality of the fixing members are arranged side by side, the reinforcing member is connected to one connecting portion, and a plurality of connecting portions are connected to the other connecting portion A connecting member may be attached to connect the fixing members.

The reinforcing member may be a diagonal member, and the reinforcing member may be connected so as to connect the fixing members respectively fixed to the structures arranged apart from each other.

The reinforcing member may be a reinforcing beam, and the reinforcing member may be connected so as to connect the fixed members respectively fixed to the structures arranged substantially parallel to each other.

In the fixed member having a plurality of connecting portions, the reinforcing member connected to at least one connecting portion is a reinforcing beam, and the reinforcing member connected to at least one other connecting portion is a diagonal member. The reinforcing beams connect the fixed members respectively fixed to the structures arranged substantially parallel to each other, and the diagonal members are fixed to the structures arranged apart from each other. The fixed members may be connected to each other.

The structure is an angle steel, a C-shaped steel, or a T-shaped steel having plate-shaped portions in directions perpendicular to each other , and the plate-shaped portions in one direction are connected to the first clamping portion and the first clamping portion. 2 clamping parts, and the space is capable of avoiding interference between the first clamping member and the plate-like part in the other direction perpendicular to the one direction of the structure. is desirable.

According to the first invention, since the fixing member can be attached to the structure by sandwiching the structure such as the angle steel between the pair of holding members, drilling or the like to the structure is unnecessary. Therefore, it can be easily attached to an existing structure. In addition, since the reinforcing member is attached to the connecting portion of the pair of fixing members, the object to be reinforced can be reinforced efficiently.

Further, at this time, since the first clamping portion protrudes in the clamping direction, the structure can be clamped with stronger pressure, and displacement of the fixing member with respect to the structure can be suppressed. In addition, since the portion other than the first holding portion is separated from the structure due to the projection margin of the first holding portion, it is possible to suppress interference between other members such as rivets attached to the structure and the fixing member. can do.

Further, by connecting a plurality of fixing members, even a reinforcing member to which a larger force is applied can be reliably attached.

Moreover, if the reinforcing member is a diagonal member such as a brace or a brace, seismic reinforcement can be efficiently performed.

Further, if the reinforcing member is a reinforcing beam, the reinforcing member can be connected so as to connect the structures arranged substantially parallel to each other.

Further, by providing a plurality of connecting portions on one fixing member, it is possible to connect a plurality of reinforcing members to the fixing member. For example, in a fixed member having a plurality of joints, a reinforcing beam is connected to one joint and a diagonal member is connected to the other joint, thereby attaching the diagonal member and the reinforcing beam with a single fixing member. can be done.

Moreover, such a fixing member is particularly suitably applicable when the structure is an angle steel, a C-shaped steel, or a T-shaped steel.

ADVANTAGE OF THE INVENTION According to this invention, the reinforcement structure of the reinforcement object which can perform the seismic reinforcement to a structure can be provided, without performing a drilling process.

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, and FIG. 2 is an assembled perspective view showing the fixing member 1. FIG. Further, FIG. 3(a) is a side view showing, as an example, a state in which a T-shaped steel 21a is sandwiched between the fixing members 1, and FIG. 3(b) is a cross-sectional view taken along line EE of FIG. 3(a). is.

The fixing member 1 is mainly composed of a holding member 3a as a first holding member, a holding member 3b as a second holding member, a bolt 5 as a joining member, a nut 7, a washer, and the like. The fixing member 1 is a member for attaching a reinforcing member to an angle steel or the like (angle steel, C-shaped steel, T-shaped steel, or the like).

As shown in FIG. 3(b), joint portions 8a, which are first joint portions, are formed in the vicinity of both end portions in the length direction of one holding member 3a (left and right direction in FIG. 3(b)). be provided. A hole 15a is formed in each joint portion 8a. The hole 15a is a joint with the other holding member 3b.

Sandwiching portions 6a, which are first sandwiching portions, are provided inside the joint portions 8a. The holding portion 6a protrudes toward the side facing the holding member 3b. That is, the holding portion 6a protrudes downward from the lower surface of the joint portion 8a, and a step is formed between the holding portion 6a and the lower surface of the joint portion 8a.

The protrusion of the clamping portion 6a from the lower surface of the joint portion 8a is approximately several mm to 100 mm, more preferably approximately several mm to 50 mm. Interference with a rivet or the like (for example, D in FIG. 3) provided on the angle steel or the like can be avoided by providing a sufficient protrusion margin. The length of the holding portion 6a (the length in the horizontal direction in FIG. 3(b)) is, for example, about 5 mm to 30 mm. By reducing the contact area between the clamping portion 6a and the angle steel or the like, the clamping portion 6a can be pressed against the angle steel or the like more strongly, thereby suppressing displacement or the like with respect to the angle steel or the like. In order to further obtain such an effect, the clamping portion 6a may be roughened (red rust, blasting, etc.). In this case, since the area of the holding portion 6a is small, the processing is easy.

Moreover, the holding portion 6a is not formed continuously in the width direction of the holding member 3a (perpendicular to the longitudinal direction, which is defined as the left-right direction in FIG. 3A), but is separated at both ends in the width direction. formed by That is, the holding portion 6a is arranged separately at four locations. By doing so, the contact area with the angle steel or the like can be reduced, and the holding portion 6a can be made to bite into the angle steel or the like more. Further, as described above, even if a rivet (D in FIG. 3) or the like is arranged on the T-shaped steel 21a, the angle steel or the like can be clamped by the clamping portion 6a across the rivet.

Between the clamping portions 6a, a substantially central portion of the clamping member 3a becomes the top portion 4. As shown in FIG. That is, on both sides of the top portion 4, plate-like members are joined toward the holding member 3b, the holding portion 6a is formed outside the top portion 4, and the joining portion 8a is formed further outside the holding portion 6a. The top part 4 is a part higher in height than other parts.

A rib 11 is joined and reinforced from the top portion 4 to the joining portion 8a. The ribs 11 are arranged outside from the top portion 4 to the joint portion 8a, and are arranged in two rows in the width direction of the holding member 3a. In addition, the form of the rib 11 and the top part 4 is not restricted to the example shown in figure, and is not specifically limited.

A space 9 is provided below the top portion 4 of the holding member 3a on the side facing the holding member 3b, which will be described later. The space 9 is formed over the entire width direction of the holding member 3a. The space 9 is a portion for avoiding interference with the angle iron or the like. In the illustrated example, equipment (A in FIG. 3B), piping (B in FIG. 3B), rivets (C in FIG. 3B), etc. are arranged above the T-shaped steel 21a. Even if the space 9 is large enough, interference with the clamping member 3a can be avoided. In addition, in the present embodiment, the holding member 3a has a symmetrical shape when viewed from the front.

The holding member 3b is a plate-like member and is arranged so as to face the holding member 3a. In the holding member 3b, the portion facing the holding portion 6a of the holding member 3a is the holding portion 6b, which is the second holding portion, and the portion facing the joint portion 8a of the holding member 3a is the second joint portion. 8b. That is, the holding portion 6b is also arranged separately at four locations. A rib 17 is provided on the rear side of the holding member 3b.

The holding portion 6b protrudes toward the holding member 3a. Therefore, when an angle steel or the like is sandwiched between the sandwiching portions 6a and 6b, the contact area between the sandwiching portion 6b and the angle steel or the like can be reduced. Displacement from steel or the like can be suppressed.

Incidentally, like the fixing member 1g shown in FIG. 4, the holding portions 6a and 6b may be formed continuously in the width direction of the holding member 3a. That is, the holding portions 6a and 6b may be arranged separately at two locations (one at each location in the longitudinal direction of the holding member 3a). In this way, the arrangement of the holding portions 6a and 6b is not particularly limited as long as they protrude in the direction opposite to each other. It may be arranged only at one place, or it may be arranged separately at three or more places in the width direction. As long as the clamping portion 6a can clamp the angle iron or the like without any deviation, the clamping portion 6b may be flat without protruding from other portions.

A hole 15b is formed in the joining portion 8b corresponding to the hole 15a of the joining portion 8a when the holding member 3b is arranged to face the holding member 3a. A bolt 5 is inserted through the holes 15 a and 15 b and joined with a nut 7 . That is, the holding member 3a and the holding member 3b are joined on both sides of the space 9 by bolts 5 and nuts 7, which are joining members. By doing so, as shown in FIGS. 3(a) and 3(b), the holding portion 6a of the holding member 3a and the holding portion 6b of the holding member 3b form a T-shaped steel 21a (angle steel or the like). It is possible to clamp by sandwiching a part of. The joining members may not be the bolt 5 and the nut 7, the nut 7 may be integrated with the clamping member, and the hole 15a or the hole 15b may be formed with a female thread.

A connecting portion 13 extending in a direction protruding from the clamping member 3a is formed further outside one joint portion 8b of the clamping member 3b. The connecting portion 13 is provided with, for example, a hole to which a reinforcing member can be attached.

Note that the connecting portion 13 may be formed on the side of the holding member 3a instead of being formed on the holding member 3b. 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 so as to extend in the width direction instead of extending in the length direction of the fixing member 1 . Further, the connecting portion 13 may be formed in the height direction of the fixing member 1 (vertical direction in FIG. 3, above the holding member 3a or below the holding member 3b). Moreover, the connecting portion 13 does not necessarily need to project like a plate, and a hole may be formed directly 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. 5 is a plan view showing a reinforcing structure 20 using the fixing member 1, FIG. 6 is an enlarged view of the J portion of FIG. 5, and FIG. 7 is a cross-sectional view taken along the line KK of FIG.

A reinforcement object 23 in the reinforcement structure 20 is composed of structures 23a and 23b that are substantially perpendicular to each other. For example, the structure 23a is the beam of the reinforcement object 23, and the structure 23b is the pillar of the reinforcement object 23. FIG. In the illustrated example, the structure 23a is formed by a T-shaped steel 21a. The structures 23a and 23b need not be beams and columns, and can be applied to any reinforcement object as long as at least one of them is formed of angle steel, T-shaped steel, or C-shaped steel. is. The T-shaped steel 21a of the structure 23a is sandwiched between the sandwiching members 3a and 3b, and the fixing member 1 is fixed to the structure 23b.

A pair of fixing members 1 are arranged side by side and fixed to each of the structures 23a orthogonal to each other. That is, one pair of fixing members 1 is fixed to one structure 23a, and the other pair of fixing members 1 is fixed to the other adjacent structure 23a. That is, the fixing member 1 is fixed to each of the T-shaped steels 21a that are spaced apart from each other. At this time, as shown in FIGS. 6 and 7 , the pair of fixing members 1 are connected by a connecting member 35 at one connecting portion 13 . Similarly, a connecting member 35a is attached and connected between a pair of fixing members 1 fixed to respective structures 23a that are orthogonal to each other. The connecting member 35a is a plate-like member and is arranged obliquely with respect to the structure 23a.

As shown in FIG. 5, fixing members 1 connected by connecting members 35, 35a are also arranged diagonally with respect to the rectangular space surrounded by the structures 23a, 23b. . End portions of braces 45, which are reinforcing members, are attached to the respective connecting members 35a by means of pins 39, bolt welding, weld joint, or the like so as to connect the respective connecting members 35a. The brace 45 is arranged in a direction substantially orthogonal to the oblique portion of the connecting member 35a. The brace 45 is, for example, a wire or a bar material, and a turnbuckle or the like (not shown) is used for the brace 45 .

Thus, in the reinforcing structure 20, the pair of fixed members 1 are fixed to the T-shaped steels 21a that constitute the object to be reinforced 23 and are arranged apart from each other, and the fixed members 1 are reinforcing members. They are connected by braces 45 . In addition, although the example shown in FIG. 6 shows an example in which the fixing member 1 is disposed only on two structures 23b that are orthogonal to each other and adjacent to each other, the present invention is not limited to this.

When the structure 23b is a pillar, the braces 45 may be arranged in a plurality of directions because the direction and number of beams joined by the corner pillars, side pillars, and center pillars are different. For example, as shown in the upper left of FIG. 5, by fixing the fixing member 1 to each of the three adjacent structures 23a and connecting them with the connecting member 35a, the center structure 23b can be fixed in two directions. A brace 45 can be attached. Further, as shown in the lower right or lower left of FIG. 5, by fixing the fixing member 1 to each of the four adjacent structures 23a and connecting them with the connecting member 35a, the central structure 23b can be fixed. Brace 45 can be attached in three or four directions. 5, the connection member 35a may be used instead of the connection member 35 even in the direction in which the brace 45 is not arranged.

As described above, according to the present embodiment, since the space 9 is provided to avoid interference with the angle steel or the like, there is no interference between the angle steel or the like and the fixing member 1, and the angle steel or the like is held between the pair of holding members 3a and 3b. can do. Therefore, the fixing member 1 can be fixed to the reinforcing object 23 without drilling the angle iron or the like. In addition, it is easy to attach and detach the fixing member 1 as necessary.

In addition, since the holding portions 6a and 6b protrude in directions facing each other and can be strongly pressed against the angle steel or the like, the holding portions 6a and 6b bite into the angle steel or the like, and the holding member 3a and the holding member 3a are separated from each other. It is possible to suppress the deviation of 3b with respect to the angle iron or the like. Therefore, the reinforcing member can be fixed to the reinforcing object 23 more reliably.

Moreover, by connecting a plurality of fixing members 1 side by side as necessary, a large reinforcing member or the like can be securely attached.

In addition, by making the size of the space 9 larger than the angle steel, it is possible to support multiple sizes of angle steel, etc., and it is possible to support even when other parts are arranged in the angle steel, etc. is.

In this embodiment, the fixing member 1 is fixed to the structural body 23a and the brace 45 is provided to connect the two, but the fixing member 1 may be provided to both the structural bodies 23a and 23b. That is, the braces 45 may be arranged also in the direction orthogonal to the plan view shown in FIG.

Also, in this embodiment, the brace 45 is shown as a reinforcing member, but instead of the brace 45, a brace using channel steel or the like may be used. That is, by obliquely arranging a diagonal member as a reinforcing member so as to connect the angle irons and the like arranged in directions substantially perpendicular to each other, the object to be reinforced 23 can be reinforced efficiently. . In the following description, the brace 45 is used as an example of the diagonal material.

In addition, although this embodiment demonstrated the case where the structure 23a was the T-shaped steel 21a, it is not restricted to this. FIG. 8(a) is a diagram showing an example using the fixing member 1a.

The fixing member 1a has substantially the same configuration as the fixing member 1, but the shape of the holding portion 6a is different. In the following description, the same reference numerals as those in FIGS. 1 to 7 are given to the configurations having the same functions as those of the above-described embodiment, and overlapping descriptions are omitted. Further, in the following drawings, the illustration of reinforcing members is omitted unless otherwise specified.

When fixing to the L-shaped angle steel 21 like the fixing member 1a shown in FIG. In this case, when the angle iron 21 is sandwiched between the fixing members 1a, a gap is formed between the joint portions 8a and 8b on the side where the sandwiching portion 6a is not provided.

FIG. 8(b) is a diagram showing an example using the fixing member 1b. The fixing member 1b has substantially the same configuration as the fixing member 1, but the configuration of the holding member 3b is different. The clamping member 3b of the fixed member 1b is formed with a top portion 4 in substantially the same manner as the clamping member 3a.

A space 9 is formed between the top portions 4 of the clamping members 3a and 3b facing each other. That is, the space 9 is provided in both the clamping member 3a and the clamping member 3b. The fixing member 1b can correspond to a structure in which the T-shaped steels 21a are arranged back to back and arranged in a substantially cross shape. In this case, the connecting portion 13 may be formed on one of the holding members 3b, or the connecting portions 13 may be provided on both of the holding members 3a and 3b. Further, the connecting portion 13 may be formed on the top portions 4 of the holding members 3a and 3b, or may be provided outside the joint portions 8a and 8b.

Although there is no problem when the T-shaped steels 21a are in back-to-back contact with each other, when gaps are formed between the individual T-shaped steels 21a as shown in the figure, at least A spacer 37 is arranged in the gap between the T-shaped steels 21a in the direction of sandwiching between the sandwiching members 3a and 3b. By doing so, the plurality of T-shaped steels 21a can be reliably sandwiched and fixed by the sandwiching members 3a and 3b.

In each of the above-described embodiments, an example in which the L-shaped angle steel 21 or the T-shaped steel 21a is arranged singly or in combination has been shown, but the present invention is not limited to this. For example, C-shaped steel or the like may be arranged singly or in combination. In addition, as long as there is a portion that can be sandwiched between the sandwiching portions 6a and 6b, the structure to be sandwiched is not limited to angle steel, T-shaped steel, and C-shaped steel, and other structures may be used. . By forming the space 9 in such a size and shape that it does not interfere with the structural body such as the angle steel, it is possible to fix the space 9 to reinforcement objects having various cross-sectional shapes.

Further, the fixing member is not limited to one having a substantially rectangular space. FIG. 9(a) is a side view showing the state of use of the fixing member 1c, and FIG. 9(b) is a sectional view taken along line GG of FIG. 9(a). The fixing member 1c has substantially the same configuration as that of the fixing member 1, but the overall shape is different. Although the T-shaped steel 21a is used in the following description, it can be replaced with a C-shaped steel or an angle steel.

The sandwiching member 3a has a pair of ribs 11 facing each other, and the top portion 4 is arranged substantially in the center between the ribs 11, and the ribs 11 are joined together. A joint portion 8a is provided in the vicinity of both ends of the rib 11, and the tip portion of the rib 11 serves as a holding portion 6a inside the joint portion 8a. In addition, as described above, the holding portion 6a protrudes downward from the joint portion 8a. In this case, the outside of the holding portion 6a is formed obliquely toward the outside of the joining portion 8a.

The ribs 11 form a pentagonal space 9 having a substantially home base shape. That is, the vicinity of the apex 4 at approximately the center of the holding member 3a is the highest, and the height gradually decreases toward both sides from the apex 4. formed in Thus, the shape of the holding member 3a is not particularly limited, and any shape such as an inverted V shape or an arc shape can be applied.

Further, in each of the above-described embodiments, a plurality of plate-like members are joined together to constitute the fixing member, but all of them may be integrally constructed. FIG. 10(a) is a side view showing the state of use of the fixing member 1d, and FIG. 10(b) is a sectional view taken along line HH of FIG. 10(a). The fixing member 1d has substantially the same configuration as the fixing member 1, but differs in that each part is integrally configured. In the fixing member 1d, both the holding members 3a and 3b are made of casting, for example.

The clamping member 3a is provided with joints 8a near both ends thereof, a clamping part 6a is formed inside the joints 8a, and a space 9 is formed between the clamping parts 6a. The space 9 has a substantially rectangular shape with curved corners. In this way, the clamping members 3a and 3b can also be constructed integrally.

Further, FIG. 11(a) is a side view showing the state of use of the fixing member 1e, and FIG. 11(b) is a sectional view taken along the line II of FIG. 11(a). As with the fixing member 1d, the fixing member 1e is integrally formed with each part. The fixing member 1e differs in the shape of the space 9 from the fixing member 1d. In this way, even when each configuration is configured integrally, the form of the space 9 is not particularly limited and can be any form. In this manner, the holding members 3a and 3b may be formed by joining members such as plate-like ribs 11 by welding or the like, or may be integrally formed as a whole.

Next, a second embodiment will be described. FIG. 12 is a front view showing the reinforcing structure 20a, and FIG. 13 is a sectional view taken along line LL of FIG. The reinforcing structure 20a has substantially the same structure as the reinforcing structure 20, but differs in that the reinforcing member is a reinforcing beam 47 instead of a diagonal member.

A plurality of fixing members 1 are attached side by side to each of the structures 23b that are spaced apart from each other and arranged substantially parallel to each other. The structure 23b is configured by, for example, a pair of angle irons 21 arranged back-to-back in a T-shape. In addition, the plurality of fixing members 1 are connected by a connecting member 35 on one side of the fixing member 1 (the side opposite to the facing direction of the structures 23b arranged apart from each other). Reinforcing beams 47 are connected to the connecting portions 13 of the fixed member 1 on the sides facing each other by bolts 33 and nuts 31 via connecting members 35b. The reinforcing beams 47 are connected so as to connect the fixed members 1 each fixed to the angle steel 21 of the structure 23b.

The reinforcing beams 47 are arranged substantially perpendicular to the structure 23b. The reinforcing beams 47 may be channel steel or angle steel, for example.

According to the second embodiment, effects similar to those of the first embodiment can be obtained. Note that the reinforcing beams 47 may be anything as long as they connect structures that are spaced apart from each other and are arranged substantially parallel to each other.

Next, a third embodiment will be described. FIG. 14(a) is a partial front view showing a reinforcing structure 20b, and FIG. 14(b) is an enlarged view of part M in FIG. 14(a). In the reinforcing structure 20b, the fixing member 1 is fixed to each of the structures 23b that are spaced apart and arranged substantially parallel to each other, and the fixing member 1 is also fixed to the structure 23a that is substantially orthogonal to the structures 23b. be. That is, both the structures 23a and 23b are made of angle steel or the like.

A reinforcing beam 47 is connected as a reinforcing member to one connecting portion 13 of the fixed member 1 fixed to the structure 23b. A brace 45 is connected as a reinforcing member to the other connecting portion 13 of the fixed member 1 . As described above, the reinforcing beams 47 connect the fixed members 1 fixed to the angle irons 21 arranged substantially parallel to each other. A brace 45, which is a diagonal member, is connected so as to connect the fixed members 1 fixed to the structures 23a and 23b that are substantially perpendicular to each other.

According to the third embodiment, effects similar to those of the first embodiment and the like can be obtained. Also, a plurality of reinforcing members can be connected to one fixing member 1 .

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

Next, FIG. 15, which describes a fourth embodiment, is a plan view of a reinforcing structure 20c. The reinforcement structure 20c is substantially similar to the reinforcement structure 20b, but differs in that the reinforcement structure 20c uses a fixing member 1f.

The fixing member 1f has substantially the same structure as the fixing member 1, but in addition to the connecting portions 13 on both sides of the joint portion 8b of the holding member 3b, a connecting portion 13a is provided above the top portion 4 of the holding member 3a. be done. The connecting portion 13a is provided in a direction substantially orthogonal to the pair of connecting portions 13 provided on the holding member 3b. That is, in one fixed member 1f, connecting portions 13 and 13a are provided at three locations.

In the reinforcing structure 20c, the structural bodies 23b are arranged at four locations so as to be substantially rectangular in plan view. Reinforcing members are joined to one adjacent structure 23b (two locations on the lower side in the figure) in three directions of the fixing member 1f. More specifically, a reinforcing beam 47 is connected to one connecting portion 13 of the fixing member 1f of the reinforcing structure 20c, and a brace 45 is connected to the other connecting portion 13. A reinforcing beam 47 is connected.

Reinforcing members are fixed to the other adjacent structures 23b (two positions on the upper side in the drawing) in two mutually orthogonal directions of the fixing member 1f. More specifically, a reinforcing beam 47 is connected to one connecting portion 13 and connecting portion 13a of the fixing member 1f of the reinforcing structure 20c. The reinforcing beams 47 connect the fixing members 1f facing each other. In this manner, the reinforcing members can be connected to the fixing member 1f at two or more points in arbitrary directions different from each other.

According to the fourth embodiment, effects similar to those of the third embodiment can be obtained. Also, like the fixing member 1f, the connecting portions 13 and 13a may be formed in directions perpendicular to each other.

Although the reinforcing beam 47 is connected to the connecting portion 13a of the fixing member 1f, the present invention is not limited to this. For example, the reinforcing beams 47 may be connected to all of the connecting portions 13 and 13a, and the brace 45 may be connected to the connecting portion 13a. Thus, in the fixed member 1f, the reinforcing beam may be connected to at least one connecting portion, and the diagonal member may be connected to at least one other connecting portion.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the technical scope of the present invention is not influenced by the above-described embodiments. It is obvious that a person skilled in the art can conceive various modifications or modifications within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. be understood to belong to

For example, it goes without saying that each configuration of the fixing member described above can be combined with each other.
