Abstract
Description
本発明は、建築構造物を構成する梁に形成される貫通孔に溶接され、当該梁を補強する梁補強金具に関するものである。 The present invention relates to a beam reinforcing bracket that is welded to a through hole formed in a beam constituting a building structure and reinforces the beam.
従来、建築構造物の梁には配管や配線を通すために貫通孔が形成されることがある。この場合、貫通孔により梁の強度が低下する。この梁の強度低下を防ぐため貫通孔に梁補強金具を嵌合し、梁補強金具の外周部を梁に溶接し、梁の補強を行っている。 Conventionally, a through hole may be formed in a beam of a building structure in order to pass piping and wiring. In this case, the strength of the beam is reduced by the through hole. In order to prevent the strength of the beam from being lowered, a beam reinforcing bracket is fitted into the through hole, and the outer periphery of the beam reinforcing bracket is welded to the beam to reinforce the beam.
図7は、梁補強金具60を示す図であり、図8は梁補強金具60を梁67へ取り付けた状態を示す図である。梁補強金具60は内部に配管を通すための配管孔65を有し、外周にフランジ61とテーパ状の挿入部63を有している。図8(a)に示すように、梁67には孔69が設けられている。図8(b)に示すように、梁補強金具60が、梁67に設けられた孔69にフランジ61が梁67に当接するまで挿入される。 FIG. 7 is a view showing the beam reinforcing metal fitting 60, and FIG. 8 is a view showing a state in which the beam reinforcing metal fitting 60 is attached to the beam 67. The beam reinforcing metal fitting 60 has a piping hole 65 for passing piping inside, and has a flange 61 and a tapered insertion portion 63 on the outer periphery. As shown in FIG. 8A, a hole 69 is provided in the beam 67. As shown in FIG. 8B, the beam reinforcing metal fitting 60 is inserted into the hole 69 provided in the beam 67 until the flange 61 comes into contact with the beam 67.
図9(a)は、梁補強金具60が梁67に取り付けられた状態を示す断面図であり、図9(b)は図9(a)のB部拡大図である。梁補強金具60の挿入部63の外周と梁67の孔69の内面とは溶接により固定され、梁67と梁補強金具60とが一体化される。この際、溶接部71の溶接高さは図9(b)に示すように梁67の厚さと同等以上に取られる。梁補強金具60と梁67とが確実に接合されたことを把握するためである。 FIG. 9A is a cross-sectional view showing a state in which the beam reinforcing bracket 60 is attached to the beam 67, and FIG. 9B is an enlarged view of a portion B in FIG. 9A. The outer periphery of the insertion portion 63 of the beam reinforcing bracket 60 and the inner surface of the hole 69 of the beam 67 are fixed by welding, and the beam 67 and the beam reinforcing bracket 60 are integrated. At this time, the welding height of the welded portion 71 is set to be equal to or greater than the thickness of the beam 67 as shown in FIG. This is for grasping that the beam reinforcing bracket 60 and the beam 67 are securely joined.
このような梁と溶接される梁補強金具としては、例えば、梁に設けられた貫通孔の周縁部に一方の面側の全周が溶接された梁の補強構造がある(特許文献1)。また、貫通孔より径の大きなフランジ部を有し、梁に形成された貫通孔の周縁部に外周部が溶接固定される梁補強金具がある(特許文献2)。
しかし、特許文献1あるいは特許文献2記載の発明では梁と梁補強金具との溶接強度が考慮されていないという問題がある。このため、本来必要である梁と梁補強金具との溶接強度以上の溶接が施される場合が多い。すなわち、本来、梁と梁補強金具との溶接強度は、梁補強金具の有する強度を大幅に超える必要はない。溶接部が破損する前に、梁補強金具自体が破損するためである。この場合、梁補強金具と梁との溶接高さは、梁の肉厚よりも十分に低い場合が多い。 However, the invention described in Patent Document 1 or Patent Document 2 has a problem that the welding strength between the beam and the beam reinforcing bracket is not considered. For this reason, there are many cases where welding that is higher than the welding strength between the beam and the beam reinforcing bracket, which is originally necessary, is performed. That is, originally, the welding strength between the beam and the beam reinforcing bracket does not need to greatly exceed the strength of the beam reinforcing bracket. This is because the beam reinforcing bracket itself is damaged before the welded portion is damaged. In this case, the welding height between the beam reinforcing bracket and the beam is often sufficiently lower than the thickness of the beam.
しかし、梁と梁補強金具との溶接高さを規定しても、梁補強リングの全周にわたり溶接高さを逐一測定しながら溶接を行う必要があり、作業性が悪くコスト増を招く。更に、梁と梁補強金具の溶接部の溶接範囲に過不足が生じやすく、また溶接強度のばらつきが生じやすいという問題がある。一方、溶接高さを安全を見て高めに溶接すれば、必要以上に広い範囲が溶接され、溶接作業に余分な手間と時間が掛かり、溶接コストが高くなるという問題がある。また、溶接時間が長くなると、梁や梁補強金具が熱変形を起こす恐れがあるという問題がある。 However, even if the welding height between the beam and the beam reinforcing bracket is defined, it is necessary to perform welding while measuring the welding height over the entire circumference of the beam reinforcing ring, resulting in poor workability and increased cost. Furthermore, there is a problem that the welding range of the welded portion between the beam and the beam reinforcing bracket tends to be excessive or insufficient, and variation in welding strength is likely to occur. On the other hand, if the welding height is increased with safety in mind, a wider range is welded than necessary, and there is a problem that the welding work takes extra time and effort and the welding cost increases. Moreover, when welding time becomes long, there exists a problem that a beam and a beam reinforcement metal fitting may raise | generate a thermal deformation.
本発明は、このような問題に鑑みてなされたもので、その目的とするところは、梁補強金具を梁孔に溶接する際、必要な溶接範囲が簡単にわかる溶接範囲特定部を有し、必要十分な溶接強度が安定して容易に得られる梁補強金具を提供することにある。 The present invention has been made in view of such a problem, and the purpose thereof is to have a welding range specifying part that can easily understand a necessary welding range when welding a beam reinforcing bracket to a beam hole, An object of the present invention is to provide a beam reinforcing metal fitting that can stably and easily obtain necessary and sufficient welding strength.
前述した目的を達成するため、第1の発明は、梁に形成された貫通孔に設けられるリング状の梁補強金具であって、前記貫通孔より外径が大きいフランジ部と、前記貫通孔より外径が小さく、前記貫通孔に挿入される挿入部と、を具備し、前記挿入部は、前記貫通孔との溶接範囲を示す溶接範囲特定部を有することを特徴とする梁補強金具である。 In order to achieve the above-mentioned object, the first invention is a ring-shaped beam reinforcing bracket provided in a through-hole formed in a beam, and includes a flange portion having an outer diameter larger than the through-hole, and a through-hole. The beam reinforcing bracket is characterized in that it has a small outer diameter and an insertion portion that is inserted into the through hole, and the insertion portion has a welding range specifying portion that indicates a welding range with the through hole. .
前記溶接範囲特定部は、前記挿入部に設けられた段差であってもよく、または 前記挿入部は、テーパ形状であり、前記溶接範囲特定部は、前記挿入部のテーパ角度の変化部であってもよい。 The welding range specifying part may be a step provided in the insertion part, or the insertion part has a tapered shape, and the welding range specifying part is a changing part of a taper angle of the insertion part. May be.
また、前記溶接範囲特定部は、前記挿入部の表面粗度の変化部であってもよく、または 前記溶接範囲特定部は、前記挿入部に設けられた色分け部であってもよい。また、前記溶接範囲特定部は、前記溶接範囲と他の部位との境界に設けた線であってもよい。 Further, the welding range specifying part may be a surface roughness changing part of the insertion part, or the welding range specifying part may be a color-coded part provided in the insertion part. Moreover, the line provided in the boundary of the said welding range and another site | part may be sufficient as the said welding range specific | specification part.
前記溶接範囲は、前記梁補強金具と前記梁との溶接強度が、前記梁補強金具の破断強度よりも大きくなるための最低限の溶接高さであってもよい。 The welding range may be a minimum welding height for a welding strength between the beam reinforcing bracket and the beam to be larger than a breaking strength of the beam reinforcing bracket.
本発明によれば、梁補強金具の挿入部が、溶接範囲が簡単にわかる溶接範囲特定部を有しているので、梁補強金具を梁貫通孔に溶接する際、溶接を過剰に行うことがなく、溶接高さを逐一測定することなく、梁補強金具と梁との溶接強度にばらつきのない梁補強金具を提供することができる。これにより、溶接作業の品質が安定し、溶接作業に余分な手間と時間を掛けることなく、必要十分な梁補強強度を得ることができる。 According to the present invention, since the insertion portion of the beam reinforcing bracket has a welding range specifying portion in which the welding range can be easily understood, excessive welding can be performed when welding the beam reinforcing bracket to the beam through hole. In addition, it is possible to provide a beam reinforcing bracket with no variation in welding strength between the beam reinforcing bracket and the beam without measuring the welding height one by one. As a result, the quality of the welding operation is stabilized, and a necessary and sufficient beam reinforcement strength can be obtained without taking extra effort and time for the welding operation.
以下、本発明の実施の形態を詳細に説明する。図1は本発明の第1の実施の形態にかかる梁補強金具を示す図であり、図2は本発明の梁補強金具を梁に使用した状態を示す図である。 Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 is a diagram showing a beam reinforcing bracket according to a first embodiment of the present invention, and FIG. 2 is a diagram showing a state in which the beam reinforcing bracket of the present invention is used for a beam.
梁補強金具1は梁11に配管を通すために内部を貫通する配管孔7を有している。梁補強金具1の片面にはフランジ3が設けられる。フランジ3は、梁11に設けられた孔13よりも大きな外径を有している。フランジ3の他面にはフランジ3より外径の小さな円筒状の挿入部5が設けられる。挿入部5は、梁11に設けられた孔13の径よりも小さい外径を有している。フランジ3は梁補強金具1を梁11の孔13に挿入する際、軸方向の位置決めに使われる。この挿入部5の外周面には後に説明する溶接範囲特定部としての段部9が設けられている。段部9は、挿入部5の外周全周にわたり設けられる。ここで、段部9とは挿入部5に設けられた挿入部5の径を違えた段差のことである。
The beam reinforcing metal fitting 1 has a pipe hole 7 penetrating the inside thereof so as to pass the pipe through the beam 11. A
なお、梁補強金具1の挿入部5は、フランジ3側から他面に向って径が小さくなるテーパ形状あるが、挿入部5は外径が一定の円筒状であってもよい。また、梁補強金具1の材質は一定以上の強度を有すれば良く、例えば、鋼材、ステンレス鋼などが使用できる。
In addition, although the insertion part 5 of the beam reinforcement metal fitting 1 has a taper shape in which a diameter becomes small toward the other surface from the
図2(a)は梁補強金具1を梁11に設置した状態の断面図である。梁補強金具1は梁11の孔13にフランジ3が梁11に当接するまで挿入される。梁補強金具1はフランジ3が梁11に当接することで、梁補強金具1の梁11に対する軸方向の位置は正確に決められる。梁補強金具1の位置が決まった後、梁補強金具1のフランジ3側よりフランジ3外周部を数点、梁11に点溶接し、梁補強金具を梁11に仮止めする。その後、梁補強金具1と梁11は、梁補強金具1の挿入部5側より溶接部15を挿入部5の全周にわたり溶接され、一体化される。溶接は例えば被覆アーク溶接で行われる。
FIG. 2A is a cross-sectional view of a state in which the beam reinforcing bracket 1 is installed on the beam 11. The beam reinforcing bracket 1 is inserted into the hole 13 of the beam 11 until the
図2(b)は図2(a)のA部を拡大した図であり、溶接部15の断面詳細を示している。tは梁補強金具1との関係で得られる最低限の溶接高さを示しており、フランジ3の面からのこの最低限溶接高さtで示した範囲が溶接範囲である。溶接範囲は梁補強金具1を梁11と溶接し一体化する際、この範囲を溶接すれば必要十分な溶接強度が得られるという溶接の範囲のことである。挿入部5に設けた段部9はこの溶接範囲を特定する溶接範囲特定部であり、フランジ3の面から最低限の溶接高さtだけ離れた挿入部5の外周部に設けられる。従って、溶接作業者は溶接作業時、フランジ3の面から、この溶接範囲特定部である段部9が溶接部15により全周に亘り隠れるまで溶接することで、必要十分な溶接強度が得られる。
FIG. 2B is an enlarged view of a portion A in FIG. 2A, and shows details of a cross section of the welded portion 15. t indicates the minimum welding height obtained in relation to the beam reinforcing bracket 1, and the range indicated by the minimum welding height t from the surface of the
最低限の溶接高さtは、梁補強金具固有の値である。すなわち、溶接高さtは、梁補強金具1と梁11との溶接強度が、梁補強金具1の破断強度よりも大きくなるための最低限の溶接高さであり、フランジ3及び挿入部5の断面積和をa、梁11の孔13の直径をdとすれば、最低限の溶接高さtは、おおよそ次式で表される。
t=2a/d
The minimum welding height t is a value unique to the beam reinforcing bracket. That is, the welding height t is the minimum welding height for the welding strength between the beam reinforcing bracket 1 and the beam 11 to be larger than the breaking strength of the beam reinforcing bracket 1. If the sum of the cross-sectional area is a and the diameter of the hole 13 of the beam 11 is d, the minimum welding height t is approximately expressed by the following equation.
t = 2a / d
すなわち、図2(a)の紙面に垂直に梁補強金具1へ引張力を加えた場合に、梁補強金具1が有する断面積(2a)よりも、溶接部15の溶接範囲(孔13の径に該当する長さdと溶接高さtとの積で溶接範囲の断面積とする)が大きければ、溶接部15で破断せずに、梁補強金具1自体で破断する。従って、梁補強金具1の強度以上の溶接強度を得るための溶接範囲は、無駄であるといえる。なお、実際の溶接高さの算出に当たっては、溶接部の強度と梁補強金具1の強度との違いも考慮することが望ましい。また、実際の段部9の高さtは、上記式に多少の安全を見て、上記式で求まるtよりも若干大きめとすることが望ましい。 That is, when a tensile force is applied to the beam reinforcing bracket 1 perpendicular to the paper surface of FIG. 2A, the welding range of the welded portion 15 (the diameter of the hole 13) is larger than the cross-sectional area (2a) of the beam reinforcing bracket 1. If the product of the length d corresponding to (2) and the welding height t (the cross-sectional area of the welding range) is large, the beam reinforcing bracket 1 itself is broken without breaking at the welded portion 15. Therefore, it can be said that the welding range for obtaining a welding strength higher than the strength of the beam reinforcing metal fitting 1 is useless. In calculating the actual weld height, it is desirable to consider the difference between the strength of the welded portion and the strength of the beam reinforcing bracket 1. Further, it is desirable that the actual height t of the stepped portion 9 is slightly larger than t obtained by the above formula, considering the safety of the above formula.
このように、本実施の形態にかかる梁補強金具1によれば、梁補強金具ごとに必要な溶接強度を考慮して、必要な溶接強度を得るための溶接範囲特定部として段部9を有しているため、必要以上に溶接を行なうことがなく、溶接作業を効率よく行うことができ、このため安価かつ容易に溶接を行うことができる。また、段部9が隠れるまで溶接を行えば良く、必要な溶接範囲を容易に視認することができるため、梁補強金具1の全周に亘り溶接高さを逐一測定する必要がなく、また、溶接ばらつきが生じにくいため安定した溶接品質を得ることができる。 Thus, according to the beam reinforcing bracket 1 according to the present embodiment, the step 9 is provided as a welding range specifying portion for obtaining a required welding strength in consideration of the welding strength required for each beam reinforcing bracket. Therefore, welding is not performed more than necessary, and the welding operation can be performed efficiently. Therefore, welding can be performed inexpensively and easily. In addition, welding may be performed until the stepped portion 9 is hidden, and a necessary welding range can be easily visually recognized. Therefore, it is not necessary to measure the welding height over the entire circumference of the beam reinforcing bracket 1, and Stable welding quality can be obtained because welding variations are less likely to occur.
次に、第2の実施の形態にかかる梁補強金具20について説明する。以下の実施の形態において、図1〜図2に示す梁補強金具1と同一の機能を果たす構成要素には、図1〜図2と同一番号を付し、重複した説明を避ける。図3は、梁補強金具20の梁11への取り付け部近傍の拡大断面図を示す。梁補強金具20は、挿入部5の外周部に、溶接範囲特定部としての角度変化部21が設けられる。角度変化部21は、挿入部5のテーパ角度が変化(図中α)している部位である。すなわち、梁補強金具20は、フランジ3からtの位置でテーパ角度がα変化している。

In the following embodiment, the same number as FIG. 1-2 is attached | subjected to the component which performs the same function as the beam reinforcement metal fitting 1 shown in FIGS. 1-2, and the overlapping description is avoided. FIG. 3 shows an enlarged cross-sectional view of the vicinity of the attachment portion of the beam reinforcing bracket 20 to the beam 11. The beam reinforcing bracket 20 is provided with an angle changing portion 21 as a welding range specifying portion on the outer peripheral portion of the insertion portion 5. The angle changing portion 21 is a portion where the taper angle of the insertion portion 5 is changed (α in the figure). In other words, the taper angle of the beam reinforcing bracket 20 is changed by α at the position t from the
第2の実施の形態にかかる梁補強金具20によれば、第1の実施の形態と同様の効果を得ることができる。角度変化部21が視認できなくなるまで溶接すれば良いため、容易に溶接範囲を特定することができる。 According to the beam reinforcing bracket 20 according to the second embodiment, the same effects as those of the first embodiment can be obtained.

Since welding may be performed until the surface roughness changing portion 31 becomes invisible, the welding range can be easily specified. Further, the surface roughness changing portion 31 can be easily provided by changing the processing speed or the like.

Next, the beam reinforcing bracket 40 according to the fourth embodiment will be described. FIG. 5 shows a side view of the beam reinforcing bracket 40.
