以下、図面に基づいて本発明に好適な実施形態を詳細に説明する。図１は、第１の実施形態に係る梁補強金具１を示す平面図であって、図２は図１の裏面図である。
また、図３は図１のＡ−Ａ断面図であって、図４は図１のＢ−Ｂ断面図である。
DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail based on the drawings. FIG. 1 is a plan view showing a beam reinforcing bracket 1 according to the first embodiment, and FIG. 2 is a back view of FIG.
3 is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 4 is a cross-sectional view taken along the line BB in FIG.
図１および図２に示すように、梁補強金具１の本体３は外周が略真円形のリング状の形状を有しており、外周部に薄肉状のフランジ部５を有し、フランジ部５と本体３の間にはテーパ部７が設けられている。また、梁補強金具１の中心部には楕円形状の貫通孔９が設けられている。
梁補強金具１の材質は例えば圧延鋼材、鋳鋼、鍛鋼などである。
As shown in FIGS. 1 and 2, the main body 3 of the beam reinforcing bracket 1 has a ring shape with a substantially circular outer periphery, and has a thin flange portion 5 on the outer peripheral portion. A taper portion 7 is provided between the main body 3 and the main body 3. In addition, an elliptical through hole 9 is provided at the center of the beam reinforcing bracket 1.
The material of the beam reinforcing bracket 1 is, for example, rolled steel, cast steel, forged steel, or the like.
ここで、貫通孔９が楕円形状であるため、図３および図４に示すようにＡ−Ａ断面の断面積Ｓ１、Ｓ２よりもＢ−Ｂ断面の断面積Ｓ３、Ｓ４の方が小さくなっている。
即ち、Ａ−Ａ断面よりもＢ−Ｂ断面のほうが強度および剛性が小さい。
そのため、梁に梁補強金具１を取り付ける際は、梁成方向の欠損の大きい位置にＡ−Ａ断面が来るように、かつ梁軸方向にＢ−Ｂ断面が来るようにして取り付けるのが望ましい。
Here, since the through hole 9 has an elliptical shape, the cross-sectional areas S3 and S4 of the BB cross section are smaller than the cross-sectional areas S1 and S2 of the AA cross section as shown in FIGS. Yes.
In other words, the BB cross section has lower strength and rigidity than the AA cross section.
For this reason, when attaching the beam reinforcing bracket 1 to the beam, it is desirable that the A-A cross section be located at a position where there is a large defect in the beam forming direction and that the BB cross section be located in the beam axis direction.
なお、梁補強金具１の径方向の断面積は、Ａ−Ａ断面からＢ−Ｂ断面に向かうに従って徐々に小さくなるように変化する。 In addition, the cross-sectional area of the radial direction of the beam reinforcement metal fitting 1 changes so that it may become small gradually as it goes to a BB cross section from an AA cross section.
次に、梁補強金具１の取り付け方法について説明する。図５は梁補強金具１を取り付ける前の梁１５の貫通孔１７付近を示す図であって、図６は図５のＣ−Ｃ断面図である。
また、図７は梁補強金具１を梁１５に取り付けた後の梁補強金具１および梁１５を示す図であって、図８は図７のＤ−Ｄ断面図である。
さらに、図９は梁補強金具１を取り付けた梁１５の斜視図である。
Next, the attachment method of the beam reinforcement metal fitting 1 is demonstrated. FIG. 5 is a view showing the vicinity of the through hole 17 of the beam 15 before the beam reinforcing bracket 1 is attached, and FIG. 6 is a sectional view taken along the line CC in FIG.
7 is a view showing the beam reinforcing bracket 1 and the beam 15 after the beam reinforcing bracket 1 is attached to the beam 15, and FIG. 8 is a sectional view taken along the line DD of FIG.
Further, FIG. 9 is a perspective view of the beam 15 to which the beam reinforcing bracket 1 is attached.
図５および図６に示すように、梁１５には貫通孔１７が設けられている。
取り付けの際には、図７および図８に示すように、梁補強金具１を貫通孔１７に嵌め合わせ、テーパ部７と貫通孔１７を溶接し、溶接部１９によって梁補強金具１と梁１５を固定する。
As shown in FIGS. 5 and 6, the beam 15 is provided with a through hole 17.
At the time of attachment, as shown in FIGS. 7 and 8, the beam reinforcing bracket 1 is fitted into the through hole 17, the tapered portion 7 and the through hole 17 are welded, and the beam reinforcing bracket 1 and the beam 15 are welded by the welded portion 19. To fix.
この際、図３のＡ−Ａ断面が梁成方向と平行になり、かつ、図４のＢ−Ｂ断面が梁軸方向と平行になるように梁補強金具１を取り付ける。 At this time, the beam reinforcing bracket 1 is attached so that the AA cross section of FIG. 3 is parallel to the beam forming direction and the BB cross section of FIG. 4 is parallel to the beam axis direction.
このように取り付けることによって、貫通孔１７内で梁成方向の欠損が大きい部分（強度および剛性が小さい部分）には断面積の大きい部分が、欠損が小さい部分（強度および剛性が大きい部分）には断面積の小さい部分が設けられるため、梁補強金具１を取り付けた際に、梁１５内で位置による強度および剛性の差を小さくすることができる。 By mounting in this way, a portion with a large cross-sectional area is replaced with a portion with a small defect (a portion with high strength and rigidity) in a portion with a large loss in the beam forming direction (a portion with low strength and rigidity) in the through-hole 17. Since a portion having a small cross-sectional area is provided, the difference in strength and rigidity depending on the position in the beam 15 can be reduced when the beam reinforcing bracket 1 is attached.
梁補強金具１を取り付けた梁１５に配管等を通す場合は、図９に示すように、梁補強金具１の貫通孔９に配管２０を通す。 When piping or the like is passed through the beam 15 to which the beam reinforcing bracket 1 is attached, the piping 20 is passed through the through hole 9 of the beam reinforcing bracket 1 as shown in FIG.
このように、第１の実施の形態によれば、梁補強金具１の断面積Ｓ１、Ｓ２よりも断面積Ｓ３、Ｓ４の方が小さくなっている。従って、梁補強金具１を梁１５に設けた際に、位置による強度および剛性の差を小さくすることができる。 Thus, according to the first embodiment, the cross-sectional areas S3 and S4 are smaller than the cross-sectional areas S1 and S2 of the beam reinforcing bracket 1. Therefore, when the beam reinforcing bracket 1 is provided on the beam 15, the difference in strength and rigidity depending on the position can be reduced.
次に、第２の実施形態について説明する。
図１０は、第２の実施形態に係る梁補強金具２１を示す平面図であって、図１１は図１０の裏面図である。
また、図１２は図１０のＥ−Ｅ断面図であって、図１３は図１０のＦ−Ｆ断面図である。
Next, a second embodiment will be described.
FIG. 10 is a plan view showing a beam reinforcing bracket 21 according to the second embodiment, and FIG. 11 is a rear view of FIG.
12 is a cross-sectional view taken along line EE in FIG. 10, and FIG. 13 is a cross-sectional view taken along line FF in FIG.
第２の実施形態に係る梁補強金具２１は、第１の実施形態における梁補強金具１において、貫通孔の形状ではなく、本体の板厚を変えることによって、断面積を変化させている。 In the beam reinforcing bracket 21 according to the second embodiment, the cross-sectional area is changed by changing the plate thickness of the main body instead of the shape of the through hole in the beam reinforcing bracket 1 in the first embodiment.
図１０および図１１に示すように、梁補強金具２１の本体２３は略真円形のリング状の形状を有しており、外周部に薄肉状のフランジ部２５を有し、フランジ部２５と本体２３の間にはテーパ部２７が設けられている。また、梁補強金具２１の中心部には円形状の貫通孔２９が設けられている。
梁補強金具２１の材質は例えば圧延鋼材、鋳鋼、鍛鋼などである。
As shown in FIGS. 10 and 11, the main body 23 of the beam reinforcing bracket 21 has a substantially circular ring shape, and has a thin flange portion 25 on the outer peripheral portion. A taper portion 27 is provided between 23. A circular through hole 29 is provided at the center of the beam reinforcing bracket 21.
The material of the beam reinforcing bracket 21 is, for example, rolled steel, cast steel, forged steel, or the like.
ここで、図１２および図１３に示すように、Ｅ−Ｅ断面の板厚２２ａよりもＦ−Ｆ断面の板厚２２ｂの方が薄い。したがってＥ−Ｅ断面の断面積Ｓ５、Ｓ６よりもＦ−Ｆ断面の断面積Ｓ７、Ｓ８の方が小さくなっている。
即ち、Ｅ−Ｅ断面よりもＦ−Ｆ断面のほうが強度および剛性が小さい。
そのため、梁に梁補強金具２１を取り付ける際は、梁成方向の欠損の大きい位置にＥ−Ｅ断面が来るように、かつ梁軸方向にＦ−Ｆ断面が来るようにして取り付けるのが望ましい。
Here, as shown in FIGS. 12 and 13, the plate thickness 22 b of the FF cross section is thinner than the plate thickness 22 a of the EE cross section. Accordingly, the cross-sectional areas S7 and S8 of the FF cross section are smaller than the cross-sectional areas S5 and S6 of the EE cross section.
That is, the strength and rigidity of the FF cross section are smaller than those of the EE cross section.
For this reason, when attaching the beam reinforcing bracket 21 to the beam, it is desirable to attach the beam reinforcing bracket 21 so that the EE cross section comes to a position with a large defect in the beam forming direction and the FF cross section comes to the beam axis direction.
なお、梁補強金具２１の板厚は、Ｅ−Ｅ断面からＦ−Ｆ断面に行くに従って徐々に小さくなり、それに伴い、断面積も徐々に小さくなる。 In addition, the plate | board thickness of the beam reinforcement metal fitting 21 becomes small gradually as it goes to a FF cross section from an EE cross section, and a cross-sectional area also becomes small gradually in connection with it.
また、梁補強金具２１の梁１５への取り付け方法は、第１の実施形態と同様であるため、説明を省略する。 In addition, the method of attaching the beam reinforcing bracket 21 to the beam 15 is the same as in the first embodiment, and thus the description thereof is omitted.
このように、第２の実施の形態によれば、梁補強金具２１の断面積Ｓ５、Ｓ６よりも断面積Ｓ７、Ｓ８の方が小さくなっている。従って、第１の実施形態と同様の効果を奏する。 Thus, according to the second embodiment, the cross-sectional areas S7 and S8 are smaller than the cross-sectional areas S5 and S6 of the beam reinforcing bracket 21. Accordingly, the same effects as those of the first embodiment are obtained.
また、第２の実施形態によれば、梁補強金具２１の貫通孔２９を略真円形の形状とすることができ、貫通する略真円形の配管との収まりがよい。 Moreover, according to 2nd Embodiment, the through-hole 29 of the beam reinforcement metal fitting 21 can be made into a substantially perfect circular shape, and the accommodation with the substantially perfect circular piping which penetrates is good.
次に、第３の実施形態について説明する。
図１４は、第３の実施形態に係る梁補強金具３１を示す平面図であって、図１５は図１４の裏面図である。
また、図１６は図１４のＧ−Ｇ断面図であって、図１７は図１４のＨ−Ｈ断面図である。
Next, a third embodiment will be described.
FIG. 14 is a plan view showing a beam reinforcing bracket 31 according to the third embodiment, and FIG. 15 is a back view of FIG.
16 is a GG cross-sectional view of FIG. 14, and FIG. 17 is a HH cross-sectional view of FIG.
第３の実施形態に係る梁補強金具３１は、第１の実施形態における梁補強金具１において、貫通孔の形状が、その周縁が段階的に変化している。 In the beam reinforcing bracket 31 according to the third embodiment, in the beam reinforcing bracket 1 according to the first embodiment, the shape of the through-hole is changed stepwise.
図１４および図１５に示すように、梁補強金具３１の本体３３は外周が略真円形のリング状の形状を有しており、外周部に薄肉状のフランジ部３５を有し、フランジ部３５と本体３３の間にはテーパ部３７が設けられている。また、梁補強金具３１の中心部にはその周縁が段階的に変化する略楕円形状の貫通孔３９が設けられている。
梁補強金具３１の材質は例えば圧延鋼材、鋳鋼、鍛鋼などである。
As shown in FIG. 14 and FIG. 15, the main body 33 of the beam reinforcing bracket 31 has a ring shape with a substantially circular outer periphery, a thin flange portion 35 on the outer peripheral portion, and the flange portion 35. A tapered portion 37 is provided between the main body 33 and the main body 33. Further, a substantially elliptical through-hole 39 whose peripheral edge changes stepwise is provided at the center of the beam reinforcing bracket 31.
The material of the beam reinforcing bracket 31 is, for example, rolled steel, cast steel, forged steel, or the like.
ここで、図１６および図１７に示すように、貫通孔３９が略楕円形状であるため、Ｇ−Ｇ断面の断面積Ｓ９、Ｓ１０よりもＨ−Ｈ断面の断面積Ｓ１１、Ｓ１２の方が小さくなっている。
即ち、Ｇ−Ｇ断面よりもＨ−Ｈ断面のほうが強度および剛性が小さい。
そのため、梁に梁補強金具３１を取り付ける際は、梁成方向の欠損の大きい位置にＧ−Ｇ断面が来るように、かつ梁軸方向にＨ−Ｈ断面が来るようにして取り付けるのが望ましい。
Here, as shown in FIGS. 16 and 17, since the through hole 39 has a substantially elliptical shape, the sectional areas S11 and S12 of the HH section are smaller than the sectional areas S9 and S10 of the GG section. It has become.
That is, the HH cross section has lower strength and rigidity than the GG cross section.
For this reason, when attaching the beam reinforcing bracket 31 to the beam, it is desirable to attach the beam reinforcing bracket 31 so that the GG cross section comes to a position with a large defect in the beam forming direction and the HH cross section comes to the beam axis direction.
なお、梁補強金具３１の径方向の断面積は、Ｇ−Ｇ断面からＨ−Ｈ断面に行くに従って徐々に小さくなるが、貫通孔３９の周縁が階段状の形状を有しているため、断面積の変化も段階的となる。
一つの段を形成する範囲では断面積はほぼ一定となり、従って梁１５に梁補強金具３１を取り付ける際に厳密な位置決めが不要となる。
Note that the radial cross-sectional area of the beam reinforcing bracket 31 gradually decreases from the GG cross section to the HH cross section, but the peripheral edge of the through hole 39 has a stepped shape. The change in area is also gradual.
In the range where one step is formed, the cross-sectional area is substantially constant, and therefore, when the beam reinforcing bracket 31 is attached to the beam 15, strict positioning becomes unnecessary.
また、梁補強金具３１の梁１５への取り付け方法は、第１の実施形態と同様であるため、説明を省略する。 In addition, the method of attaching the beam reinforcing bracket 31 to the beam 15 is the same as in the first embodiment, and thus the description thereof is omitted.
このように、第３の実施の形態によれば、梁補強金具３１の断面積Ｓ９、Ｓ１０よりも断面積Ｓ１１、Ｓ１２の方が小さくなっている。従って、第１の実施形態と同様の効果を奏する。 Thus, according to the third embodiment, the cross-sectional areas S11 and S12 are smaller than the cross-sectional areas S9 and S10 of the beam reinforcing bracket 31. Accordingly, the same effects as those of the first embodiment are obtained.
また、第３の実施形態によれば、貫通孔３９の周縁が階段状の形状を有しているため、梁１５に梁補強金具３１を取り付ける際に厳密な位置決めが不要となり、作業性が向上する。 In addition, according to the third embodiment, since the peripheral edge of the through hole 39 has a stepped shape, strict positioning is not required when the beam reinforcing bracket 31 is attached to the beam 15, and workability is improved. To do.
次に、第４の実施形態について説明する。
図１８は、本実施形態に係る梁補強金具４１を示す平面図であって、図１９は図１８の裏面図である。
また、図２０は図１８のＩ−Ｉ断面図であって、図２１は図１８のＪ−Ｊ断面図である。
Next, a fourth embodiment will be described.
18 is a plan view showing the beam reinforcing bracket 41 according to the present embodiment, and FIG. 19 is a rear view of FIG.
20 is a cross-sectional view taken along the line II in FIG. 18, and FIG. 21 is a cross-sectional view taken along the line JJ in FIG.
第４の実施形態に係る梁補強金具４１は、第２の実施形態における梁補強金具２１において、本体２３の板厚が段階的に変化している。 In the beam reinforcing bracket 41 according to the fourth embodiment, the plate thickness of the main body 23 is changed stepwise in the beam reinforcing bracket 21 according to the second embodiment.
図１８および図１９に示すように、梁補強金具４１の本体４３は略真円形のリング状の形状を有しており、外周部に薄肉状のフランジ部４５を有し、フランジ部４５と本体４３の間にはテーパ部４７が設けられている。また、梁補強金具４１の中心部には円形状の貫通孔４９が設けられている。
梁補強金具４１の材質は例えば圧延鋼材、鋳鋼、鍛鋼などである。
As shown in FIGS. 18 and 19, the main body 43 of the beam reinforcing bracket 41 has a substantially round ring shape, and has a thin-walled flange portion 45 on the outer peripheral portion. A taper portion 47 is provided between 43. A circular through hole 49 is provided at the center of the beam reinforcing bracket 41.
The material of the beam reinforcing bracket 41 is, for example, rolled steel, cast steel, forged steel, or the like.
ここで、図２０および図２１に示すように、Ｉ−Ｉ断面の板厚４２ａよりもＪ−Ｊ断面の板厚４２ｂの方が薄い。したがってＩ−Ｉ断面の断面積Ｓ１３、Ｓ１４よりもＪ−Ｊ断面の断面積Ｓ１５、Ｓ１６の方が小さくなっている。
即ち、Ｉ−Ｉ断面よりもＪ−Ｊ断面のほうが強度および剛性が小さい。
そのため、梁に梁補強金具４１を取り付ける際は、梁成方向の欠損の大きい位置にＩ−Ｉ断面が来るように、かつ梁軸方向にＪ−Ｊ断面が来るようにして取り付けるのが望ましい。
Here, as shown in FIGS. 20 and 21, the plate thickness 42b of the JJ cross section is thinner than the plate thickness 42a of the II cross section. Therefore, the cross-sectional areas S15 and S16 of the JJ cross section are smaller than the cross-sectional areas S13 and S14 of the II cross section.
In other words, the JJ cross section has lower strength and rigidity than the II cross section.
For this reason, when attaching the beam reinforcing bracket 41 to the beam, it is desirable to attach it so that the I-I cross section comes to a position where the defect in the beam forming direction is large and the JJ cross section comes to the beam axis direction.
なお、梁補強金具４１の板厚は、Ｉ−Ｉ断面からＪ−Ｊ断面に行くに従って徐々に小さくなるが、この板厚変化は段階的であるため、断面積の変化も段階的となる。
一つの段を形成する範囲では断面積はほぼ一定となり、従って、梁１５に梁補強金具４１を取り付ける際に厳密な位置決めが不要となる。
The plate thickness of the beam reinforcing bracket 41 gradually decreases from the II section to the JJ section. However, since the plate thickness change is gradual, the cross-sectional area also changes gradually.
In a range where one step is formed, the cross-sectional area is substantially constant, and therefore, when the beam reinforcing bracket 41 is attached to the beam 15, strict positioning is not necessary.
また、梁補強金具４１の梁１５への取り付け方法は、第１の実施形態と同様であるため、説明を省略する。 Further, the method for attaching the beam reinforcing bracket 41 to the beam 15 is the same as that in the first embodiment, and thus the description thereof is omitted.
このように、第４の実施の形態によれば、梁補強金具４１の断面積Ｓ１３、Ｓ１４よりも断面積Ｓ１５、Ｓ１６の方が小さくなっている。従って、第２の実施形態と同様の効果を奏する。 Thus, according to the fourth embodiment, the cross-sectional areas S15 and S16 are smaller than the cross-sectional areas S13 and S14 of the beam reinforcing bracket 41. Accordingly, the same effects as those of the second embodiment are obtained.
また、第４の実施形態によれば、本体４３の板厚が段階的に変化しているため、梁１５に梁補強金具４１を取り付ける際に厳密な位置決めが不要となり、作業性が向上する。 In addition, according to the fourth embodiment, since the plate thickness of the main body 43 changes stepwise, strict positioning is not necessary when the beam reinforcing bracket 41 is attached to the beam 15, and workability is improved.
