Description

The present invention relates to, for example, a reinforcing structure of a reinforcing object to which a reinforcing member for seismic reinforcement is attached.

In recent years, seismic retrofitting of structures has been carried out as a countermeasure against large earthquakes. For example, there are a method of providing diagonal timbers (braces and canes) diagonally to structures such as columns and beams, and a method of providing reinforcing beams so as to connect structures arranged parallel to each other.

For such a structure, L-shaped angle steel, C-shaped steel or T-shaped steel (hereinafter, simply referred to as “angle steel or the like”) may be used. The angle steel and the like are used, for example, when they are used alone, or when a plurality of angle steels and the like are combined to form a T-shape or a cross shape.

When attaching a reinforcing member or the like to an object to be reinforced using such angle steel or the like, a method of drilling a hole in the angled steel or the like and fixing the reinforcing member to the angled steel or the like with a bolt or the like is used. It is common (for example, Patent Documents 1 and 2).

However, when drilling a hole in angle steel or the like, the strength of the angle steel or the like decreases, which is not desirable as a reinforcing structure. Further, since it takes time to drill holes in angle steel or the like, there is a problem that the working time becomes long.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a reinforcing structure of a reinforced object capable of performing seismic retrofitting to a structure or the like without performing drilling. ..

In order to achieve the above-mentioned object, the present invention is a reinforcing structure of the object to be reinforced, the structure including angle steel, C-shaped steel or T-shaped steel, the first sandwiching member, and the first A fixing member having a second sandwiching member joined to face the sandwiching member, sandwiching and fixing the angle steel, C-shaped steel or T-shaped steel, and a reinforcing member connected to the fixing member. And, at least the first sandwiching member has a notch on the surface facing the second sandwiching member to avoid interference with the angle steel, C-shaped steel or T-shaped steel. A connecting portion to which the reinforcing member is connected is provided on at least one of the first sandwiching member or the second sandwiching member, and the angle steel, C-shaped steel or T-shaped steel are arranged apart from each other. It is a reinforcing structure of a reinforcing object, characterized in that the fixing members are fixed to each other, and the reinforcing member is attached so as to connect the connecting portions of the fixing members.

A plurality of the first sandwiching members may be used for the one second sandwiching member, and the first sandwiching member may be joined side by side to the second sandwiching member.

The reinforcing member is a diagonal member, and the reinforcing member may be connected so as to connect the fixing members fixed to the angle steel, the C-shaped steel, or the T-shaped steel, which are arranged apart from each other. ..

The reinforcing member is a reinforcing beam, and the reinforcing member may be connected so as to connect the fixing members fixed to the angle steel, the C-shaped steel, or the T-shaped steel, which are arranged substantially parallel to each other. ..

The at least one fixing member is provided with the connecting portion at two or more places.
The reinforcing member may be connected to each of the connecting portions.

In the fixing member having the plurality of the connecting portions, the reinforcing member connected to at least one of the connecting portions is a reinforcing beam, and the reinforcing member connected to the other at least one connecting portion is a diagonal member. The reinforcing beams connect the fixing members fixed to the angle steel, the C-shaped steel, or the T-shaped steel, which are arranged substantially parallel to each other, and the diagonal members are arranged apart from each other. The fixing members fixed to the angle steel, the C-shaped steel, or the T-shaped steel may be connected so as to be connected to each other.

According to the first invention, since the fixing member can be attached to the angle steel or the like by sandwiching the angle steel or the like between the pair of holding members, it is not necessary to drill holes in the angle steel or the like. Therefore, it can be easily attached to an existing structure. Further, since the reinforcing member is attached to the connecting portion of the pair of fixing members, the object to be reinforced can be efficiently reinforced.

Further, a plurality of other sandwiching members may be arranged side by side with respect to one sandwiching member. By doing so, even a reinforcing member to which a larger force is applied can be easily attached.

Further, if the reinforcing member is a diagonal member such as a brace or a cane, 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 angle steels, C-shaped steels, or T-shaped steels arranged substantially parallel to each other.

Further, by providing a plurality of connecting portions in one fixing member, a plurality of reinforcing members can be connected to the fixing member.

For example, in a fixing member having a plurality of connecting portions, the diagonal member and the reinforcing beam can be attached by one fixing member by connecting a reinforcing beam to one connecting portion and connecting a diagonal member to the other connecting portion. Can be done.

According to the present invention, it is possible to provide a reinforcing structure of a reinforcing object capable of performing seismic retrofitting to a structure without performing drilling.

(A) is a diagram showing the reinforcing structure 20b, and (b) is an enlarged view of the G portion 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, which is a sectional view taken along the line AA of FIG. be.

The fixing member 1 is mainly composed of a holding member 3a which is a first holding member, a holding member 3b which is a second holding member, a bolt 5 which is a joining member, a nut 7, and the like. The fixing member 1 is a member for attaching a reinforcing member to angle steel or the like. The materials of the sandwiching member 3a and the sandwiching member 3b are not particularly limited, but are, for example, steel.

As shown in FIG. 3, in one of the sandwiching members 3a, a mountain-shaped portion 4 is formed in a substantially central portion in the length direction (the left-right direction in FIG. 3) of the fixing member 1. The mountain-shaped portion 4 is a portion having a height higher than other portions. Both sides of the chevron portion 4 with respect to the length direction of the fixing member 1 project in a plate shape, a sandwiching portion 6a is formed on the outside of the chevron portion 4, and a joint portion 8a is formed on the outer side of the pinching portion 6a. To.

The side surface of the mountain-shaped portion 4 and the upper surfaces of the sandwiching portion 6a and the joint portion 8a projecting in a plate shape are connected by ribs 11 to be reinforced. The ribs 11 have a substantially triangular plate shape, and are formed in the vicinity of both end portions of the sandwiching member 3a in the width direction (vertical to the longitudinal direction and perpendicular to the paper surface of FIG. 3). The sandwiching member 3a may be formed by joining plate-shaped ribs 11 by welding or the like, or may be integrally formed as a whole.

For example, when the rib 11 is integrally formed, the shape of the rib 11 does not have to be plate-shaped as in the fixing member 1e shown in FIG. In the fixing member 1e, the rib 11 is formed so that the height gradually decreases and the width increases from substantially the center of the mountain-shaped portion 4 in the width direction toward the sandwiching portion 6a and the joining portion 8a. Further, a part of the rib 11 is cut out on the upper surface of the joint portion 8a in order to avoid interference with the nut 7 and the like. In this way, when the sandwiching member 3a is integrally formed by casting or the like, it may have a form such as the fixing member 1e. The form of the rib 11 and the chevron portion 4 is not limited to the illustrated example, and is not particularly limited.

The mountain-shaped portion 4 of the sandwiching member 3a is provided with a notch portion 9 on the side facing the sandwiching member 3b, which will be described later. The notch portion 9 is formed over the entire width direction of the sandwiching member 3a. The notch portion 9 is a portion for avoiding interference with angle steel or the like. In this embodiment, as shown in FIG. 3, a plurality of angle steels 21 are arranged in a substantially T-shape (inverted T-shape in the figure). Therefore, the notch portion 9 is formed in a substantially T shape so as to avoid interference with the angle steel 21.

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

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

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

The portions of the sandwiching portion 6b and the joint portion 8b of the sandwiching member 3b are slightly thinner than the portions on both sides in the length direction thereof. Therefore, steps 17 are formed on both sides of the joint portion 8b of the sandwiching member 3b in the length direction so that the wall thickness becomes thicker. Each step 17 is formed along the width direction of the sandwiching member 3b. That is, the sandwiching member 3a is arranged between the steps 17 on both sides of the sandwiching member 3b.

On the outer side of one joint portion 8b of the sandwiching member 3b, a connecting portion 13 extending in a direction protruding from the sandwiching member 3a is formed. For example, a hole is provided in the connecting portion 13, and a reinforcing member can be attached to the connecting portion 13.

The connecting portion 13 may be formed on the sandwiching member 3a side instead of being formed on the sandwiching member 3b. That is, the connecting portion 13 is provided on at least one of the sandwiching member 3a or the sandwiching member 3b. Further, the connecting portion 13 may be formed by extending 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 (in the vertical direction of FIG. 3, 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 the reinforcing structure using the fixing member 1 will be described. 5 is a view showing a reinforcing structure 20 using the fixing member 1, FIG. 6 is an enlarged perspective view of a portion B of FIG. 5, and FIG. 7 is a sectional view taken along line CC of FIG.

The reinforcing object 23 in the reinforcing structure 20 is composed of structures 23a and 23b that are substantially orthogonal to each other. The structures 23a and 23b are formed of angle steel 21. In the present embodiment, in a part of the structures 23a and 23b, a pair of angle steels 21 are arranged back to back, and are arranged in a substantially T shape as a whole. The angle steel 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 steels 21 arranged apart from each other. The ends of the braces 45 are attached to the connecting portions 13 of each pair of fixing members 1 by pins 37. That is, the brace 45, which is 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 turnbuckle or the like (not shown) is used for the brace 45.

FIG. 8 is an enlarged view of part D of FIG. 7. As described above, a part of the angle steel 21 is sandwiched between the sandwiching portion 6a of the sandwiching member 3a and the sandwiching portion 6b of the sandwiching member 3b. At this time, a slight gap 35 is formed between the joint portion 8a of the sandwiching member 3a and the joint portion 8b of the sandwiching member 3b. By doing so, the angle steel 21 can be reliably sandwiched between the sandwiching portion 6a and the sandwiching portion 6b.

The notch portion 9 is formed sufficiently larger than the angle steel 21 except for the sandwiching portions 6a and 6b in which the angle steel 21 is sandwiched. That is, the angle steel 21 may have a gap formed between the holding members 3a and 3b other than the holding portions 6a and 6b. By doing so, the fixing member 1 of one size can be applied to the angle steel 21 of a plurality of sizes.

As described above, according to the present embodiment, since the notch portion 9 corresponding to the shape of the angle steel 21 is provided, there is no interference between the angle steel 21 and the fixing member 1, and the angle steel 21 is held by the pair of sandwiching members 3a and 3b. Can be sandwiched between. Therefore, the fixing member 1 can be fixed to the reinforcing object 23 without drilling a hole in the angle steel 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 and the holding member 3b from being displaced from each other when a force is applied to the holding member 3b in the length direction. 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 reinforcing object 23. In addition, in order to engage the sandwiching members 3a and 3b at the step 17, it is desirable that the height of the step 17 is higher than the gap 35 of the joint portions 8a and 8b described above.

Further, by increasing the size of the notch portion 9 with respect to the angle steel 21, it is possible to support a plurality of sizes of angle steel 21.

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

Further, in the present embodiment, the brace 45 is shown as the reinforcing member, but the brace 45 may be replaced with a cane using channel steel or the like. That is, the reinforcing object 23 can be efficiently reinforced by arranging diagonal members as reinforcing members diagonally so as to connect the angle steels 21 arranged in directions substantially orthogonal to each other. .. In the following description, an example of the brace 45 as the diagonal member will be used.

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

The fixing member 1a has almost the same structure as the fixing member 1, but the form of the notch portion 9 is different. In the following description, the same reference numerals as those in FIGS. 1 to 8 will be added to the configurations that perform the same functions as those of the above-described embodiment, and duplicate description will be omitted. Further, in the following figures, unless otherwise specified, the reinforcing members are not shown.

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

Further, FIG. 9B is a diagram showing an example in which the fixing member 1b is used. The fixing member 1b has almost the same structure as the fixing member 1, but the form of the holding member 3b is different. A mountain-shaped portion 4 is formed on the holding member 3b of the fixing member 1b in substantially the same manner as the holding member 3a.

The sandwiching members 3a and 3b have substantially T-shaped notches 9 in their respective chevron portions 4 facing each other. That is, the notch portion 9 is provided in both the sandwiching member 3a and the sandwiching member 3b. When the notches 9 of the sandwiching members 3a and 3b are joined to each other so as to face each other, the shape of the notches 9 becomes substantially cross-shaped. As described above, 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.

There is no problem when the individual angle steels 21 are in contact with each other back to back, but as shown in the figure, when a gap is formed between the individual angle steels 21, at least The spacer 39 is arranged in the gap between the angle steels 21 in the direction of being sandwiched between the sandwiching members 3a and 3b. By doing so, the plurality of angle steels 21 can be reliably sandwiched and fixed by the sandwiching members 3a and 3b.

In this way, by designing the shape of the notch portion 9 or the like according to the form of the angle steel 21, it can be fixed to a structure of any form.

In each of the above-described embodiments, an example in which the L-shaped angle steel 21 is arranged alone or in combination is shown, but the present invention is not limited to this. For example, C-shaped steel, T-shaped steel, and the like may be arranged alone or in combination. As described above, the present invention can be fixed to an object having a cross-sectional shape other than the L-shape. In this case, the shape of the notch portion 9 may be formed so as not to interfere with the angle steel or the like according to the arrangement of the angle steel or the like. In the following description, angle steel 21 will be used, but it may be replaced with C-shaped steel or T-shaped steel.

Further, the fixing member does not have to be composed of one holding member 3a and one holding member 3b. For example, as in the fixing member 1c shown in FIG. 10, one holding member 3b may be joined to the three holding members 3a. That is, a plurality of sandwiching members 3a are joined side by side to one sandwiching member 3b. By doing so, it is easier to install as compared with the case where a plurality of fixing members 1 are provided side by side.

Next, the 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.

Fixing members 1d are attached to the structures 23b which are separated from each other and arranged substantially parallel to each other so that the connecting portions 13 face each other. As with the fixing member 1c, the fixing member 1d is fixed with a plurality of holding members 3a attached 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 fixed to the angle steel 21 of the structure 23b.

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

According to the second embodiment, the same effect as that of the first embodiment can be obtained. The reinforcing beams 47 may be any structure that connects the structures that are separated from each other and arranged substantially in parallel.

That is, the fixing member 1f is provided with a plurality of connecting portions 13a and 13b.

In the reinforcing structure 20b, the fixing member 1f is fixed to each of the structures 23b which are separated from each other and arranged substantially parallel to 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 so as to face each other in opposite directions. Further, the fixing member 1c is fixed to the structure 23a which is substantially orthogonal to the structure 23b.

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

According to the third embodiment, the same effect as that of the first embodiment can be obtained. Further, by arranging a plurality of connecting portions 13a and 13b on one fixing member 1f, a 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, but 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, or the brace 45 may be connected to both the connecting portions 13a and 13b.
