Description

本発明は、例えば柱及び梁からなる構造体に対して補強部材が固定された構造体への補強部材の固定構造等に関するものである。 TECHNICAL FIELD The present invention relates to a structure for fixing a reinforcing member to a structure in which a reinforcing member is fixed to a structure composed of, for example, columns and beams.

従来、例えば方杖やブレースのように、柱と梁からなる構造体に対して補強部材を斜めに固定して、構造体を補強する方法がある。例えば、既設の柱や梁に、補強部材を固定することで、既存の構造体を補強することができる。このような補強部材は、例えば溶接によって柱や梁に接合される。 Conventionally, there is a method of reinforcing a structure by obliquely fixing a reinforcing member to a structure composed of columns and beams, such as a brace or a brace. For example, an existing structure can be reinforced by fixing a reinforcing member to an existing pillar or beam. Such reinforcing members are joined to columns or beams, for example by welding.

また、補強部材を溶接ではなく、H形鋼からなる柱や梁のフランジ部にプレートによって固定する方法がある(特許文献1)。 In addition, there is a method of fixing a reinforcing member to a flange portion of a column or beam made of H-shaped steel with a plate instead of welding (Patent Document 1).

特開2013-177797号公報JP 2013-177797 A

しかし、柱や梁に対して、例えば高所で補強部材を溶接する場合には、高所において、ビードなどが飛び散る場合があり、溶接作業時に、下方で他の作業を並行して行うことができず、作業効率が悪い。また、火気厳禁の工場などでは溶接作業を行うことができない。 However, when welding reinforcement members to columns and beams at high places, for example, beads and the like may scatter at high places, and other work must be done in parallel with the welding work below. I can't do it and work efficiency is bad. In addition, welding work cannot be performed in factories where fire is strictly prohibited.

これに対し、特許文献1のように、溶接を行わずに補強部材を柱や梁に固定する方法によれば、上述した問題は回避することができる。しかし、特許文献1のように、H形鋼のフランジ部に補強部材を固定すると、それぞれのフランジ部を一対の部材で挟み込む必要があることから、部品点数が多く、多数のボルトを用いるため、固定のために多くの作業時間を要する。 On the other hand, according to the method of fixing the reinforcing member to the column or the beam without welding as in Patent Document 1, the above-described problems can be avoided. However, if reinforcing members are fixed to the flanges of the H-section steel as in Patent Document 1, each flange must be sandwiched between a pair of members. A lot of work time is required for fixation.

一方、補強部材をフランジではなくウェブに固定しようとすると、力がかかった際に、ウェブが変形して、十分に柱と梁との間で力を伝達できないおそれがある。 On the other hand, if the reinforcing member is fixed to the web instead of the flange, the web may deform when force is applied, and the force may not be sufficiently transmitted between the column and the beam.

本発明は、このような問題に鑑みてなされたもので、作業性に優れ、効率よく構造体を補強することが可能な構造体への補強部材の固定構造及びH形鋼用固定部材を提供することを目的とする。 The present invention has been made in view of such problems, and provides a structure for fixing a reinforcing member to a structure and a fixing member for an H-section steel, which is excellent in workability and capable of efficiently reinforcing the structure. intended to

前述した目的を達成するため、第1の発明は、柱又は梁に補強部材を有する構造体への補強部材の固定構造であって、前記柱又は前記梁の一方が、第1のH形鋼からなり、前記第1のH形鋼のウェブに接合される第1の固定部材と、前記第1の固定部材に接合される補強部材と、を具備し、前記第1の固定部材は、一対の挟持部材を有し、少なくとも一対の前記挟持部材が、前記第1のH形鋼のウェブを挟み込むように配置されてボルトで固定され、前記第1のH形鋼のフランジの対向方向に対して、前記挟持部材と前記第1のH形鋼のウェブの略中央部との間に隙間が形成され、前記第1の固定部材は、一対の前記挟持部材と複数の受け部材を有し、前記受け部材は伸縮可能な棒状部材であり、前記受け部材は、前記第1のH形鋼のウェブの両側に配置され、前記受け部材の両端が、前記第1のH形鋼のフランジ近傍のウェブに接触し、前記挟持部材は、前記受け部材を介して前記第1のH形鋼のウェブを挟み込むことを特徴とする構造体への補強部材の固定構造である。 In order to achieve the above object, a first invention is a structure for fixing reinforcing members to a structure having reinforcing members on columns or beams, wherein one of the columns or beams is a first H-section steel. a first fixing member joined to the first H-section steel web; and a reinforcing member joined to the first fixing member, wherein the first fixing member comprises a pair of clamping members, at least a pair of said clamping members being arranged to sandwich the web of said first H-section steel and fixed with bolts, with respect to the facing direction of the flanges of said first H-section steel a gap is formed between the clamping member and a substantially central portion of the first H-section steel web , the first fixing member having a pair of clamping members and a plurality of receiving members, The receiving member is an extendable rod-shaped member, the receiving member is arranged on both sides of the web of the first H-section steel, and both ends of the receiving member are located near the flanges of the first H-section steel. A structure for fixing a reinforcing member to a structure, wherein the clamping member is in contact with the web and clamps the web of the first H-section steel through the receiving member .

この場合には、前記受け部材の内部には空間を有し、前記第1のH形鋼のフランジ間に配置された状態で、内部に固化材が充填されて、前記受け部材の長さが固定されてもよい。 In this case, the receiving member has a space inside and is filled with a solidifying material in a state of being arranged between the flanges of the first H-section steel so that the receiving member has a length of May be fixed.

また、前記受け部材の両端部には、前記第1のH形鋼のフランジとウェブとの間のフィレット部の形状に対応した外形のアタッチメントが取り付けられ、前記アタッチメントを介して、前記受け部材が前記フィレット部近傍と接触してもよい。 Attachments having an outer shape corresponding to the shape of the fillet portion between the flange and the web of the first H-section steel are attached to both ends of the receiving member, and the receiving member is attached via the attachment. It may come into contact with the vicinity of the fillet portion.

前記構造体は、前記第1のH形鋼と、前記第1のH形鋼と略直交して接合される第2のH形鋼と、を具備し、前記第2のH形鋼の長手方向と、前記第1のH形鋼の弱軸方向とが略一致し、前記補強部材の一端は、前記第2のH形鋼に接合される第2の固定部材と前記第1の固定部材の両方に接合されてもよい。 The structure includes the first H-section steel and a second H-section steel joined substantially perpendicular to the first H-section steel, and the longitudinal direction of the second H-section steel The direction substantially coincides with the weak axis direction of the first H-section steel, and one end of the reinforcing member is joined to the second H-section steel, and the second fixing member and the first fixing member may be joined to both

前記第2の固定部材は、補強金具と端部材を有し、少なくとも一対の前記補強金具が、前記第2のH形鋼のウェブを挟み込むように配置されてボルトで固定されるとともに、それぞれの前記補強金具と前記端部材とで前記第2のH形鋼のフランジを挟み込んだ状態で、前記補強金具と前記端部材とがボルトで接合され、前記端部材に前記補強部材の一端が固定されてもよい。 The second fixing member has a reinforcing metal fitting and an end member, and at least a pair of the reinforcing metal fittings are arranged so as to sandwich the web of the second H-beam steel and are fixed with bolts. The reinforcing metal fitting and the end member are joined with bolts in a state in which the flange of the second H-section steel is sandwiched between the reinforcing metal fitting and the end member, and one end of the reinforcing member is fixed to the end member. may

第1の発明によれば、一対の挟持部材で第1のH形鋼のウェブを挟み込み、挟持部材がボルトで接合されるため、溶接作業が不要である。また、挟持部材を一対のフランジのそれぞれに取り付ける場合と比較して、部品点数が少なくて済み、取り付け作業が容易である。 According to the first invention, the first H-section steel web is sandwiched between the pair of clamping members, and the clamping members are joined with bolts, eliminating the need for welding work. In addition, compared to the case where the clamping member is attached to each of the pair of flanges, the number of parts can be reduced, and the attachment work is easy.

また、挟持部材でウェブを挟み込んだ際に、ウェブのフランジ近傍において挟持部材と接触するが、フランジから離れた略中央部には、挟持部材とウェブとの間に隙間が形成される。したがって、挟持部材からの力は、ウェブの中央部近傍には伝達されず、ウェブの端部近傍(フランジ近傍)にのみ伝達される。通常、H形鋼は、ウェブの法線方向が弱軸方向となり、ウェブの面に対して垂直な方向への力に弱い。特に、ウェブの中央部近傍においてウェブに垂直な方向へ力が加わると、ウェブが大きく変形する恐れがある。 Further, when the web is sandwiched by the sandwiching members, the web contacts the sandwiching members in the vicinity of the flanges, but a gap is formed between the sandwiching members and the web at a substantially central portion apart from the flanges. Therefore, the force from the clamping member is not transmitted near the center of the web, but only near the ends of the web (near the flanges). Generally, H-section steel has a weak axis direction in the normal direction of the web, and is weak against forces in the direction perpendicular to the plane of the web. In particular, if a force is applied in the direction perpendicular to the web near the central portion of the web, the web may be greatly deformed.

これに対し、第1の発明では、ウェブの最も弱い部分への力の伝達を避け、フランジに近い部位にのみ力を伝達することで、ウェブの変形を抑制し、構造体へ力を効率よく伝達することができる。 On the other hand, in the first invention, by avoiding the transmission of force to the weakest part of the web and transmitting the force only to the part near the flange, deformation of the web is suppressed and the force is efficiently transferred to the structure. can be transmitted.

また、第1の固定部材として、受け部材を伸縮可能とすることで、H形鋼のサイズに応じて受け部材の長さを調整することができる。また、受け部材を短い状態で配置した後に、伸ばして固定することで、確実に受け部材をフランジ近傍に設置することができる。 Further, by making the receiving member expandable and contractable as the first fixing member, the length of the receiving member can be adjusted according to the size of the H-section steel. Further, by extending and fixing the receiving member after arranging it in a short state, the receiving member can be reliably installed in the vicinity of the flange.

また、受け部材を伸ばした後に、内部に固化材を充填して固化することで、受け部材の長さを固定することができる。 In addition, after stretching the receiving member, the length of the receiving member can be fixed by filling the inside with a solidifying material and solidifying it.

また、受け部材の両端部に、フランジとウェブの間のフィレット形状に対応した形状のアタッチメントを取り付けることで、受け部材からの力を、アタッチメントを介して、ウェブの端部近傍(フィレット部)に伝達することができる。 In addition, by attaching attachments with a shape corresponding to the fillet shape between the flange and the web to both ends of the receiving member, the force from the receiving member is transferred to the vicinity of the end of the web (fillet portion) via the attachment. can be transmitted.

また、補強部材を第1のH形鋼に固定される第1の固定部材のみではなく、第2のH形鋼に固定された第2の固定部材にも固定することができる。例えば、第1のH形鋼と第2のH形鋼の交差部近傍に補強部材を固定する場合には、補強部材を第1の固定部材と第2の固定部材の両方に固定することで、補強部材からの力を第1のH形鋼と第2のH形鋼の両方に伝達することができる。 Further, the reinforcing member can be fixed not only to the first fixing member fixed to the first H-section steel, but also to the second fixing member fixed to the second H-section steel. For example, when fixing the reinforcing member near the intersection of the first H-section steel and the second H-section steel, by fixing the reinforcing member to both the first fixing member and the second fixing member , the force from the reinforcing member can be transmitted to both the first H-beam and the second H-beam.

また、第2の固定部材の補強金具で第2のH形鋼のウェブを挟み込むとともに、補強金具と端部材とで第2のH形鋼のフランジを挟み込むようにすることで、第2の固定部において、補強部材からの力を効率よく第2のH形鋼に伝達することができる。 In addition, by sandwiching the web of the second H-shaped steel with the reinforcing metal fittings of the second fixing member and sandwiching the flange of the second H-shaped steel between the reinforcing metal fittings and the end member, the second fixing is achieved. , the force from the reinforcing member can be efficiently transmitted to the second H-section steel.

の発明は、H形鋼の弱軸方向へ補強部材を設置可能な固定部材であって、前記固定部材は、一対の挟持部材と複数の受け部材を有し、前記受け部材は伸縮可能な棒状部材であり、前記受け部材をH形鋼のウェブの両側に配置した際に、前記受け部材の両端を、H形鋼のフランジ近傍のウェブに接触させた状態で、前記挟持部材によって前記受け部材を介してH形鋼のウェブを挟み込むことが可能であることを特徴とするH形鋼用固定部材である。 A second invention is a fixing member capable of installing a reinforcing member in the weak axis direction of an H-section steel, the fixing member having a pair of holding members and a plurality of receiving members, the receiving members being expandable and contractable. When the receiving member is arranged on both sides of the web of the H-section steel, both ends of the receiving member are in contact with the web near the flange of the H-section steel, and the clamping member A fixing member for H-section steel, characterized in that it is possible to sandwich a web of H-section steel through a receiving member.

の発明によれば、既設の構造体に容易に固定することができ、効率よく補強部材からの力を構造体へ伝達することが可能なH形鋼用固定部材を得ることができる。 According to the second invention, it is possible to obtain a fixing member for H-section steel that can be easily fixed to an existing structure and that can efficiently transmit the force from the reinforcing member to the structure.

本発明によれば、作業性に優れ、効率よく構造体を補強することが可能な構造体への補強部材の固定構造及びH形鋼用固定部材を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, it is excellent in workability|operativity, and can provide the fixing structure of the reinforcing member to the structure which can reinforce a structure efficiently, and the fixing member for H-section steels.

(第1の実施形態)
以下、本発明の実施の形態にかかる構造体の補強構造1について説明する。図1は、構造体の補強構造1の一部を示す斜視図である。構造体の補強構造1は、柱3と梁5とからなる構造体に対する補強構造である。
(First embodiment)
A reinforcing structure 1 for a structure according to an embodiment of the present invention will be described below. FIG. 1 is a perspective view showing part of a reinforcing structure 1 for a structure. A structure reinforcing structure 1 is a reinforcing structure for a structure composed of columns 3 and beams 5 .

図示した構造体は、第1のH形鋼である柱3と、第2のH形鋼である梁5とが略直交して接合されて構成される。柱3は、ウェブ3cと、ウェブ3cの両端に設けられるフランジ3a、3bからなる。また、梁5は、ウェブ5cと、ウェブ5cの両端に設けられるフランジ5a、5bからなる。なお、第1のH形鋼と第2のH形鋼は、いずれが柱又は梁であってもよい。又は、例えば両者が梁であってもよく、柱や梁ではない他の構造体であってもよい。 The illustrated structure is constructed by joining a column 3, which is a first H-section steel, and a beam 5, which is a second H-section steel, substantially perpendicular to each other. The column 3 consists of a web 3c and flanges 3a and 3b provided at both ends of the web 3c. The beam 5 is composed of a web 5c and flanges 5a and 5b provided at both ends of the web 5c. Either of the first H-section steel and the second H-section steel may be a column or a beam. Alternatively, for example, both of them may be beams, or they may be other structures other than columns and beams.

梁5の長手方向と柱3の弱軸方向とは略一致する。柱3と梁5との接合部近傍には、柱3および梁5に対してH形鋼用固定部材を介して、斜めに補強部材11の一端が固定される。より詳細には、柱3のウェブ3cに、第1の固定部材である固定部材30が接合され、補強部材11は、固定部材30に接合される。また、梁5のウェブ5cに、第2の固定部材である固定部材10が接合され、補強部材11は、固定部材10にも接合される。すなわち、補強部材11の一端は、梁5と柱3の両方に接合される。なお、補強部材11の他端は、他の固定部材によって他の柱、梁、床などの構造物に接合される。すなわち、本実施形態では、補強部材11は、例えば、構造体の方杖やブレースとして機能する例について説明する。 The longitudinal direction of the beam 5 and the weak axis direction of the column 3 substantially coincide. One end of a reinforcing member 11 is obliquely fixed to the column 3 and the beam 5 in the vicinity of the joint between the column 3 and the beam 5 via a fixing member for H-shaped steel. More specifically, a fixing member 30 as a first fixing member is joined to the web 3c of the column 3, and the reinforcing member 11 is joined to the fixing member 30. As shown in FIG. A fixing member 10 as a second fixing member is joined to the web 5c of the beam 5, and the reinforcing member 11 is also joined to the fixing member 10. As shown in FIG. That is, one end of the reinforcing member 11 is joined to both the beam 5 and the column 3 . The other end of the reinforcing member 11 is joined to other structures such as columns, beams, and floors by other fixing members. That is, in the present embodiment, an example in which the reinforcing member 11 functions as, for example, a brace or a brace of a structure will be described.

次に、構造体の柱3への補強部材11の固定構造について説明する。図2は、図1のA矢視断面図であり、図3は、固定部材30の分解斜視図、図4(a)は、図2のB-B線断面図である。固定部材30は、主に、H形鋼の弱軸方向へ補強部材11を設置するための部材である。 Next, the fixing structure of the reinforcing member 11 to the column 3 of the structure will be described. 2 is a cross-sectional view taken along line A in FIG. 1, FIG. 3 is an exploded perspective view of the fixing member 30, and FIG. 4(a) is a cross-sectional view taken along line BB in FIG. The fixing member 30 is mainly a member for installing the reinforcing member 11 in the direction of the weak axis of the H-section steel.

図3に示すように、固定部材30は、主に、一対の挟持部材25a、25bから構成される。挟持部材25a、25bの幅方向(H形鋼へ取り付ける際に、一対のフランジの対向方向に対応する)の両端部近傍には、凸部33が設けられる。凸部33は、互いの対向方向に突出する。少なくとも一方の挟持部材25aの背面側(凸部33が形成される側とは逆側)には、挟持部材25aに略垂直にガセットプレート27が取り付けられる。ガセットプレート27は、補強部材11が接合される部位である。なお、補強部材11とガセットプレート27とは、図示を省略したボルト等で固定される。 As shown in FIG. 3, the fixing member 30 is mainly composed of a pair of holding members 25a and 25b. Protrusions 33 are provided in the vicinity of both ends of the holding members 25a and 25b in the width direction (corresponding to the facing direction of the pair of flanges when attached to the H-section steel). The protrusions 33 protrude in directions facing each other. A gusset plate 27 is attached substantially perpendicularly to the holding member 25a on the back side of at least one of the holding members 25a (the side opposite to the side on which the projection 33 is formed). The gusset plate 27 is a portion to which the reinforcing member 11 is joined. The reinforcing member 11 and the gusset plate 27 are fixed by bolts or the like (not shown).

図1に示すように、本実施形態では、梁5が、柱3の中心ではなく、柱3の端部側(フランジ3a側)に偏心した位置に接合される。すなわち、柱3が側柱または隅柱である例を示す。補強部材11を梁5の中心位置に配置するためには、ガセットプレート27を、梁5の中心位置に配置する必要があるため、この場合には、図4(a)に示すように、ガセットプレート27は、柱3の中心から偏心した位置に配置される。すなわち、ガセットプレート27は、挟持部材25aの幅方向の中心ではなく、挟持部材25aの幅方向の一方の端部側へ偏心した位置に接合される。 As shown in FIG. 1, in the present embodiment, the beam 5 is joined not at the center of the column 3 but at an eccentric position on the end side (flange 3a side) of the column 3 . That is, an example in which the pillar 3 is a side pillar or a corner pillar is shown. In order to arrange the reinforcing member 11 at the center position of the beam 5, it is necessary to arrange the gusset plate 27 at the center position of the beam 5. In this case, as shown in FIG. The plate 27 is arranged at a position eccentric from the center of the column 3 . That is, the gusset plate 27 is not joined to the center of the holding member 25a in the width direction, but to a position eccentric to one end of the holding member 25a in the width direction.

なお、柱3が中柱の場合や、補強部材11を梁5に接合せずに柱にのみ接合する場合には、ガセットプレート27は、柱3の中心位置に配置すればよい。すなわち、挟持部材25aの幅方向の略中心位置にガセットプレート27を接合すればよい。 If the pillar 3 is a central pillar, or if the reinforcing member 11 is joined only to the pillar without being joined to the beam 5, the gusset plate 27 may be arranged at the center position of the pillar 3. That is, the gusset plate 27 may be joined to the substantially central position in the width direction of the holding member 25a.

ガセットプレート27と挟持部材25aの背面との間には複数のリブ29aが設けられる。図4(a)に示すように、略三角形のリブ29aは、挟持部材25aの幅方向の端部から、ガセットプレート27の所定の高さまで配置され、挟持部材25aおよびガセットプレート27と接合される。前述したように、ガセットプレート27には、補強部材11が接合されるため、リブ29aは、補強部材11と干渉しないように、ガセットプレート27に固定される。 A plurality of ribs 29a are provided between the gusset plate 27 and the rear surface of the holding member 25a. As shown in FIG. 4(a), the substantially triangular rib 29a is arranged from the width direction end of the holding member 25a to a predetermined height of the gusset plate 27, and is joined to the holding member 25a and the gusset plate 27. . Since the reinforcing member 11 is joined to the gusset plate 27 as described above, the rib 29 a is fixed to the gusset plate 27 so as not to interfere with the reinforcing member 11 .

図3に示すように、挟持部材25a、25bには、それぞれ孔31a、31bが設けられる。また、図4(a)に示すように、柱3のウェブ3cには、孔31a、31bに対応する部位に孔35が設けられる。少なくとも一対の挟持部材25a、25bによって柱3のウェブ3cを挟み込むように配置されて、孔31a、35、31bを貫通するようにボルト37が設けられ、挟持部材25a、25bがボルト37で固定される。 As shown in FIG. 3, the holding members 25a and 25b are provided with holes 31a and 31b, respectively. Further, as shown in FIG. 4(a), the web 3c of the column 3 is provided with holes 35 at portions corresponding to the holes 31a and 31b. At least a pair of clamping members 25a, 25b are arranged so as to sandwich the web 3c of the column 3, and bolts 37 are provided so as to pass through the holes 31a, 35, 31b. be.

挟持部材25a、25bの幅は、柱3のウェブ3cの高さ(フランジ3a、3bの間隔)よりもわずかに狭い。したがって、挟持部材25a、25bの両端部は、ウェブ3cのフランジ3a、3b近傍に位置し、挟持部材25a、25bの両端部に形成される凸部33同士でウェブ3cが挟み込まれる。 The width of the clamping members 25a, 25b is slightly narrower than the height of the web 3c of the column 3 (the distance between the flanges 3a, 3b). Therefore, both ends of the holding members 25a and 25b are located near the flanges 3a and 3b of the web 3c, and the web 3c is sandwiched between the protrusions 33 formed at both ends of the holding members 25a and 25b.

図4(b)は、図4(a)のD部拡大図である。挟持部材25a、25bでウェブ3cを挟み込むと、凸部33がウェブ3cと接触する。このように、挟持部材25a、25bをH形鋼のウェブ3cの両側に配置した際に、挟持部材25a、25bの凸部33をウェブ3cのフランジ3a、3b近傍に接触させてウェブ3cを挟み込むことができる。なお、凸部33の形状を、ウェブ3cとフランジ3a、3bとの間のフィレット部3dの形状に対応した円弧形状を形成しておくことで、凸部33をより確実にウェブ3cに接触させることができる。 FIG. 4(b) is an enlarged view of part D in FIG. 4(a). When the web 3c is sandwiched between the sandwiching members 25a and 25b, the protrusions 33 come into contact with the web 3c. In this way, when the holding members 25a and 25b are arranged on both sides of the web 3c of the H-section steel, the protrusions 33 of the holding members 25a and 25b are brought into contact with the vicinity of the flanges 3a and 3b of the web 3c to sandwich the web 3c. be able to. By forming the shape of the convex portion 33 in an arc shape corresponding to the shape of the fillet portion 3d between the web 3c and the flanges 3a and 3b, the convex portion 33 is brought into contact with the web 3c more reliably. be able to.

このように、凸部33は、柱3のウェブ3cに対して、フランジ3a、3b近傍にのみ接触し、凸部33以外の部位ではウェブ3cとは接触しない。すなわち、凸部33同士の間であって、柱3のフランジ3a、3bの対向方向に対するウェブの3c略中央部には、挟持部材25a、25bとの間に隙間39が形成される。 In this way, the convex portion 33 contacts the web 3c of the column 3 only in the vicinity of the flanges 3a and 3b, and does not contact the web 3c at portions other than the convex portion 33. FIG. That is, a gap 39 is formed between the holding members 25a and 25b between the protrusions 33 and at substantially the center of the web 3c in the direction in which the flanges 3a and 3b of the column 3 face each other.

例えば、図4(a)において、補強部材11の軸方向に力が付与されると、力は、固定部材30を介して柱3へ伝達される。この際、力がウェブ3cの全体に伝達されるのではなく、ウェブ3cのフランジ3a、3b近傍にのみ伝達される。ウェブ3cに垂直な方向に対して、フランジ3a、3b近傍と比較してウェブ3cの中央部近傍は耐力が小さく、容易に変形する。これに対し、フランジ3a、3b近傍にのみ力を伝達することで、柱3の弱軸方向に対しても、ウェブ3cの変形を抑制することができる。 For example, in FIG. 4( a ), when force is applied in the axial direction of the reinforcing member 11 , the force is transmitted to the column 3 via the fixing member 30 . At this time, the force is not transmitted to the entire web 3c, but only to the vicinity of the flanges 3a, 3b of the web 3c. In the direction perpendicular to the web 3c, the strength near the center of the web 3c is smaller than that near the flanges 3a and 3b, and is easily deformed. On the other hand, by transmitting the force only to the vicinity of the flanges 3a and 3b, it is possible to suppress the deformation of the web 3c also in the direction of the weak axis of the column 3.

次に、構造体の梁5への補強部材11の固定構造について説明する。図5は、図2のC-C線断面図であり、図6は、固定部材10の補強金具15を示す斜視図である。固定部材10は、主に、一対の補強金具15と、端部材13とから構成される。 Next, the fixing structure of the reinforcing member 11 to the beam 5 of the structure will be described. 5 is a cross-sectional view taken along the line CC of FIG. 2, and FIG. 6 is a perspective view showing the reinforcing metal fitting 15 of the fixing member 10. As shown in FIG. The fixing member 10 is mainly composed of a pair of reinforcing metal fittings 15 and end members 13 .

図5に示すように、梁5には、補強金具15がボルト21aで固定される。また、梁5に固定されたそれぞれの補強金具15と、端部材13とが、それぞれボルト21bで接合される。 As shown in FIG. 5, a reinforcing metal fitting 15 is fixed to the beam 5 with a bolt 21a. Further, each reinforcing metal fitting 15 fixed to the beam 5 and the end member 13 are joined with bolts 21b.

端部材13は例えば板状の部材であり、端部材13の背面には、ガセットプレート27が接合される。すなわち、補強部材11の端部がガセットプレート27を介して端部材13と接合される。ガセットプレート27と端部材13との間には、リブ29bが接合されて補強される。なお、端部材13は、板状でなくてもよく、例えば、所定の形状の鋳鋼などでもよい。また、端部材13とガセットプレート27は、一体で構成されてもよく、別体で構成されて接合されてもよい。また、端部材13と挟持部材25aとは接合されていてもよく、離れていてもよい。 The end member 13 is, for example, a plate-like member, and a gusset plate 27 is joined to the rear surface of the end member 13 . That is, the end portion of the reinforcing member 11 is joined to the end member 13 via the gusset plate 27 . A rib 29b is joined between the gusset plate 27 and the end member 13 for reinforcement. It should be noted that the end member 13 may not be plate-shaped, and may be cast steel having a predetermined shape, for example. Also, the end member 13 and the gusset plate 27 may be integrally constructed or separately constructed and joined together. Also, the end member 13 and the holding member 25a may be joined or separated.

図6に示すように、補強金具15は、第1の固定部である固定部19aと、第2の固定部である固定部19bとを有する。固定部19a、19bは、互いに略直交してもよいが、固定部19bの下面を、固定部19aに対して完全に直交せずに、やや鋭角に設定してもよい。固定部19aには、ボルト21aが挿通される孔23aが設けられる。また、固定部19bには、ボルト21bが挿通される孔23bが設けられる。 As shown in FIG. 6, the reinforcing metal fitting 15 has a fixing portion 19a as a first fixing portion and a fixing portion 19b as a second fixing portion. The fixed portions 19a and 19b may be substantially orthogonal to each other, but the lower surface of the fixed portion 19b may be set at a slightly acute angle instead of being completely orthogonal to the fixed portion 19a. The fixed portion 19a is provided with a hole 23a through which the bolt 21a is inserted. Further, the fixed portion 19b is provided with a hole 23b through which the bolt 21b is inserted.

図5に示すように、一対の補強金具15が、互いの固定部19aによって、梁5のウェブ5cを挟み込むように対向して配置される。梁5には、孔23dが形成され、一対の補強金具15の孔23aとウェブ5cの孔23dとが一直線上に並ぶように配置される。孔23a、23dにはボルト21aが挿通される。ボルト21aによって、補強金具15が梁5のウェブ5cに固定される。 As shown in FIG. 5, a pair of reinforcing metal fittings 15 are arranged facing each other so as to sandwich the web 5c of the beam 5 by their mutual fixing portions 19a. A hole 23d is formed in the beam 5, and the hole 23a of the pair of reinforcing metal fittings 15 and the hole 23d of the web 5c are arranged in a straight line. A bolt 21a is inserted through the holes 23a and 23d. The reinforcing metal fitting 15 is fixed to the web 5c of the beam 5 by means of bolts 21a.

補強金具15の固定部19bは、フランジ5b(補強部材11が配置される側のフランジ)の両側にフランジの外方に張り出す。固定部19bの孔23bは、フランジ5bよりも外側に配置される。フランジ5bを挟み込むようにして、固定部19bと対向する部位には、端部材13が配置される。端部材13には、孔23cが形成され、孔23b、23cにボルト21bが挿通される。すなわち、補強金具15の固定部19bと端部材13とで梁5の一方のフランジ5bを挟み、固定部19bと端部材13とがフランジ5bの外方の張り出し部において、ボルト21bによって接合される。なお、端部材13とフランジ5bとの間に、さらに接着剤を塗布して接着してもよい。 The fixing portion 19b of the reinforcing metal fitting 15 protrudes outward from both sides of the flange 5b (the flange on which the reinforcing member 11 is arranged). The hole 23b of the fixing portion 19b is arranged outside the flange 5b. An end member 13 is arranged at a portion facing the fixed portion 19b so as to sandwich the flange 5b. A hole 23c is formed in the end member 13, and a bolt 21b is inserted through the holes 23b, 23c. That is, one flange 5b of the beam 5 is sandwiched between the fixed portion 19b of the reinforcing metal fitting 15 and the end member 13, and the fixed portion 19b and the end member 13 are joined by the bolt 21b at the outwardly projecting portion of the flange 5b. . An adhesive may be further applied between the end member 13 and the flange 5b for bonding.

ここで、前述したように、固定部19bの下面を、固定部19aに対してやや鋭角にすることで、固定部19a、19bとの交差部近傍の外面(角部)を、ウェブ5cとフランジ5bとの交差部近傍と接触させることができるとともに、固定部19bの先端側において、フランジ5bとの間に隙間を形成することができる。この際、補強金具15の固定部19aと固定部19bとの角部の外面形状は、梁5のウェブ9とフランジ5bの交差部近傍のフィレット形状に対応する形状としてもよい。 Here, as described above, by making the lower surface of the fixed portion 19b at a slightly acute angle with respect to the fixed portion 19a, the outer surface (corner) near the intersection with the fixed portions 19a and 19b is formed between the web 5c and the flange. A gap can be formed between the fixing portion 19b and the flange 5b on the tip end side of the fixed portion 19b. At this time, the outer surface shape of the corner portion between the fixing portion 19a and the fixing portion 19b of the reinforcing metal fitting 15 may be a shape corresponding to the fillet shape near the intersection of the web 9 of the beam 5 and the flange 5b.

補強金具15と梁5とが、固定部19aと固定部19bとの交差部近傍(角部の外面)とウェブ5cとフランジ5bの交差部近傍とで接触することで、補強金具15にかかる力を、ウェブ5cで受けることができる。例えば、補強部材11が図5の下方に引っ張られた際に、補強部材11からの引張力は、端部材13を介して補強金具15に伝達されるが、補強金具15からの力は、ウェブ5cとフランジ5bの交差部近傍で受け止められ、ウェブ5cによって支持される。 The reinforcing metal fitting 15 and the beam 5 are in contact with each other in the vicinity of the intersection of the fixed portion 19a and the fixed portion 19b (the outer surface of the corner) and in the vicinity of the intersection of the web 5c and the flange 5b, thereby exerting a force on the reinforcing metal fitting 15. can be received at web 5c. For example, when the reinforcing member 11 is pulled downward in FIG. 5, the tensile force from the reinforcing member 11 is transmitted to the reinforcing metal fitting 15 via the end member 13, but the force from the reinforcing metal fitting 15 is transmitted to the web. It is received near the intersection of 5c and flange 5b and is supported by web 5c.

また、補強部材11は、端部材13の幅方向の略中央に接合される。すなわち、補強部材11の中心軸は、ウェブ5cの延長線上に位置する。このため、例えば、補強部材11が図5の下方から圧縮された際に、補強部材11からの圧縮力は、端部材13を介してウェブ5cで受け止められる。 Further, the reinforcing member 11 is joined to substantially the center in the width direction of the end member 13 . That is, the central axis of the reinforcing member 11 is positioned on the extension line of the web 5c. Therefore, for example, when the reinforcement member 11 is compressed from below in FIG.

このように、補強金具15から梁5への力の伝達は、固定部19aとウェブ9との間の摩擦力によるものではない。このため、ボルト21aは、固定部19aとウェブ9との間の摩擦力を発揮させるだけの軸力が不要である。すなわち、ボルト21aは、補強部材11から引張力が補強金具15のボルト21bの位置に伝達された際に、一対の補強金具15の上部が開くことを防止できる程度の軸力でよい。 Thus, the transmission of force from the reinforcing metal fitting 15 to the beam 5 is not due to the frictional force between the fixed portion 19a and the web 9. FIG. Therefore, the bolt 21a does not require an axial force sufficient to exert the frictional force between the fixed portion 19a and the web 9. As shown in FIG. That is, the bolt 21a may have an axial force that can prevent the upper portion of the pair of reinforcing metal fittings 15 from opening when tensile force is transmitted from the reinforcing member 11 to the position of the bolt 21b of the reinforcing metal fitting 15. FIG.

以上、本実施の形態によれば、溶接を用いることなく、補強部材11を柱3及び梁5に固定することができる。また、特に柱3の弱軸方向に対する補強部材11からの力を、H形鋼のウェブ3cの全体ではなく、フランジ3a、3b近傍にのみ伝達することで、ウェブ3cの変形を抑制することができる。 As described above, according to the present embodiment, the reinforcing member 11 can be fixed to the column 3 and the beam 5 without using welding. In addition, the deformation of the web 3c can be suppressed by transmitting the force from the reinforcing member 11, particularly in the direction of the weak axis of the column 3, not to the entire web 3c of the H-section steel, but only to the vicinity of the flanges 3a and 3b. can.

同様に、梁5に対する補強部材11からの力を、H形鋼のフランジ5bではなく、フランジ5bとウェブ5cとの交点近傍を起点としてウェブ5cで受けることができるため、フランジ5bの変形を抑制することができる。 Similarly, the force from the reinforcing member 11 to the beam 5 can be received not by the flange 5b of the H-shaped steel, but by the web 5c starting from the vicinity of the intersection of the flange 5b and the web 5c, so deformation of the flange 5b is suppressed. can do.

なお、本実施形態では、柱3と梁5の交差部近傍における補強部材11の固定構造について説明したが、例えば、梁5から離れた位置の柱3へ補強部材11を固定してもよい。この場合には、固定部材30のみを用いればよい。すなわち、固定部材10、30は、必ずしも同時に使用されなくてもよい。 In this embodiment, the fixing structure of the reinforcing member 11 near the intersection of the pillar 3 and the beam 5 has been described. In this case, only the fixing member 30 should be used. That is, the fixing members 10, 30 do not necessarily have to be used at the same time.

(第2の実施形態)
次に、第2の実施形態にかかる固定部材について説明する。なお、以下の説明において、第1の実施形態と同一の機能を奏する構成については、図1~図6と同一の符号を付し、重複する説明を省略する。
(Second embodiment)
Next, a fixing member according to the second embodiment will be described. In the following description, the same reference numerals as those in FIGS. 1 to 6 are given to the structures having the same functions as those in the first embodiment, and overlapping descriptions are omitted.

図7は、第2の実施形態にかかる固定部材30を用いた補強部材の固定構造を示す図であり、図8は、図7のE-E線断面図である。なお、図7においては、補強部材11及び梁5の図示を省略し、挟持部材25cとガセットプレート27の透視図とする。また、図8においては、柱3が中柱であり、ガセットプレート27が柱3の中心に配置する例を示す。 7A and 7B are diagrams showing a reinforcing member fixing structure using a fixing member 30 according to the second embodiment, and FIG. 8 is a cross-sectional view taken along line EE of FIG. 7, the illustration of the reinforcing member 11 and the beam 5 is omitted, and the holding member 25c and the gusset plate 27 are shown in perspective. 8 shows an example in which the column 3 is the center column and the gusset plate 27 is arranged at the center of the column 3. As shown in FIG.

図8に示すように、第1の固定部材である固定部材30aは、主に、一対の挟持部材25c、25dと複数の受け部材41から構成される。挟持部材25c、25dは、固定部材30の挟持部材25a、25bと略同様の構成であるが、凸部33が形成されておらず平坦な板状部材である。挟持部材25cの背面には、挟持部材25aと同様に、ガセットプレート27が接合される。 As shown in FIG. 8, the fixing member 30a, which is the first fixing member, is mainly composed of a pair of holding members 25c and 25d and a plurality of receiving members 41. As shown in FIG. The clamping members 25c and 25d have substantially the same configuration as the clamping members 25a and 25b of the fixing member 30, but are flat plate-like members in which the protrusions 33 are not formed. A gusset plate 27 is joined to the rear surface of the holding member 25c in the same manner as the holding member 25a.

柱3のウェブ3cには、複数の受け部材41とアタッチメント43が併設される。図9は、受け部材41とアタッチメント43の斜視図であり、図10は、受け部材41の断面図である。図10に示すように、受け部材41は、ねじ部47によって全体として伸縮可能な棒状部材である。受け部材41の内部には、空間51が形成され、空間51と外部とが孔45によって連通する。 A plurality of receiving members 41 and attachments 43 are arranged side by side on the web 3c of the column 3. As shown in FIG. 9 is a perspective view of the receiving member 41 and the attachment 43, and FIG. 10 is a sectional view of the receiving member 41. FIG. As shown in FIG. 10 , the receiving member 41 is a rod-shaped member that can be expanded and contracted by a screw portion 47 as a whole. A space 51 is formed inside the receiving member 41 , and the space 51 communicates with the outside through a hole 45 .

受け部材41の両端部には、アタッチメント43が取り付けられる。アタッチメント43は、受け部材41の端部が挿入される凹部49を有する。アタッチメント43は、柱3に取り付けられる際に、ウェブ3cのフランジ3a、3b近傍と接触する部位である。このため、アタッチメント43の外形は、フランジ3a、3bとウェブ3cとの間のフィレット形状に対応した円弧形状となる。 Attachments 43 are attached to both ends of the receiving member 41 . The attachment 43 has a recess 49 into which the end of the receiving member 41 is inserted. The attachment 43 is a portion that contacts the vicinity of the flanges 3a and 3b of the web 3c when attached to the pillar 3. As shown in FIG. Therefore, the outer shape of the attachment 43 is an arc shape corresponding to the fillet shape between the flanges 3a, 3b and the web 3c.

図8に示すように、受け部材41は、所定の長さに伸ばした状態で、ウェブ3cの両側に配置され、受け部材41の両端部にはアタッチメント43が取り付けられる。受け部材41の長さを、ウェブ3cの高さ(フランジ3a、3bの間隔)よりもわずかに短い状態で配置することで、アタッチメント43をウェブ3cのフランジ3a、3b近傍に接触させることができる。すなわち、アタッチメント43を介して、受け部材41の両端部をフランジ3a、3bとウェブ3cとの間のフィレット部近傍に接触させることができる。したがって、一対のアタッチメント43の間であって、フランジ3a、3bの対向方向に対するウェブ3cの略中央部において、受け部材41とウェブ3cの間には隙間39が形成される。 As shown in FIG. 8, the receiving members 41 are arranged on both sides of the web 3c while being stretched to a predetermined length, and attachments 43 are attached to both ends of the receiving members 41. By arranging the length of the receiving member 41 slightly shorter than the height of the web 3c (the interval between the flanges 3a and 3b), the attachment 43 can be brought into contact with the vicinity of the flanges 3a and 3b of the web 3c. . That is, both end portions of the receiving member 41 can be brought into contact with the vicinity of the fillet portion between the flanges 3a, 3b and the web 3c through the attachment 43. As shown in FIG. Therefore, a gap 39 is formed between the receiving member 41 and the web 3c between the pair of attachments 43 and at substantially the center of the web 3c with respect to the facing direction of the flanges 3a and 3b.

なお、受け部材41は、前述したように、長さの調整が可能である。このため、フランジ3a、3b間において、ウェブ3cの高さ(フランジ3a、3bの間隔)に対応した長さに、受け部材41を伸ばした状態で配置される。この際、孔45から受け部材41の内部の空間51に固化材53を充填して固化することで、受け部材41の長さが固定され、受け部材41の長さが変化することを抑制することができる。 The length of the receiving member 41 can be adjusted as described above. Therefore, between the flanges 3a and 3b, the receiving member 41 is arranged in an extended state to a length corresponding to the height of the web 3c (interval between the flanges 3a and 3b). At this time, by filling the space 51 inside the receiving member 41 with the solidifying material 53 through the hole 45 and solidifying, the length of the receiving member 41 is fixed, and the change in the length of the receiving member 41 is suppressed. be able to.

この状態で、ウェブ3cの両側において、挟持部材25c、25dを受け部材41の外側に配置し、ボルト37で固定する。すなわち、挟持部材25c、25dによって受け部材41を介してウェブ3cを挟み込むことができる。 In this state, the holding members 25c and 25d are arranged outside the receiving member 41 on both sides of the web 3c and fixed with bolts 37. As shown in FIG. That is, the web 3c can be sandwiched through the receiving member 41 by the sandwiching members 25c and 25d.

第2の実施形態によれば、第1の実施形態と同様の効果を得ることができる。また、伸縮可能な受け部材41を用いることで、複数のサイズのH形鋼にも適用が可能である。また、挟持部材25c、25dは凸部33が不要であり、平坦な板状部材でよいため、製造が容易である。なお、挟持部材25c、25dは、必ずしも、受け部材41の全長にわたって配置される必要がない。このため、サイズが小さくても、受け部材41に力が伝達できれば、H形鋼のサイズごとに挟持部材のサイズを製造する必要はない。 According to the second embodiment, effects similar to those of the first embodiment can be obtained. Also, by using the expandable receiving member 41, it is possible to apply to H-shaped steel of multiple sizes. In addition, since the holding members 25c and 25d do not require the protrusions 33 and may be flat plate-like members, they are easy to manufacture. It should be noted that the holding members 25c and 25d do not necessarily need to be arranged over the entire length of the receiving member 41. As shown in FIG. Therefore, even if the size is small, as long as force can be transmitted to the receiving member 41, it is not necessary to manufacture a holding member of each size for each size of the H-section steel.

また、受け部材41の内部に固化材53を充填可能とすることで、受け部材41が振動等によって短くなることが抑制され、H形鋼からの脱落や位置ずれが生じることを抑制することができる。 In addition, by allowing the solidifying material 53 to be filled inside the receiving member 41, the receiving member 41 can be prevented from being shortened due to vibration or the like, and can be prevented from coming off from the H-shaped steel or being displaced. can.

また、フィレット形状に対応した外形のアタッチメント43を用いることで、効率よく、受け部材41からの力をフランジ3a、3b近傍のウェブ3cへ伝達することができる。なお、本発明において、アタッチメント43を用い、ウェブ3cと受け部材41の間にアタッチメント43が配置される場合でも、受け部材41は、アタッチメント43を介してウェブ3cに接触しているものとする。また、アタッチメント43を用いずに、受け部材41の端部近傍の形状自体をフィレット形状に対応した外形としてもよい。 Further, by using the attachment 43 having an outer shape corresponding to the fillet shape, the force from the receiving member 41 can be efficiently transmitted to the web 3c near the flanges 3a and 3b. In the present invention, even when the attachment 43 is used and the attachment 43 is arranged between the web 3c and the receiving member 41, the receiving member 41 is assumed to be in contact with the web 3c through the attachment 43. Alternatively, without using the attachment 43, the shape of the receiving member 41 in the vicinity of the end portion itself may have an outer shape corresponding to the fillet shape.

このように、H形鋼の弱軸方向へ補強部材11を固定する際に、固定部材を、ウェブ3cの中央部付近と接触させずに、フランジ3a、3b近傍とのみ接触させることで、ウェブ3cの変形を抑制することができ、効率よく補強部材11からの力をH形鋼へ伝達することができる。 Thus, when fixing the reinforcing member 11 in the direction of the weak axis of the H-section steel, the fixing member is brought into contact only with the vicinity of the flanges 3a and 3b without coming into contact with the vicinity of the central portion of the web 3c. The deformation of 3c can be suppressed, and the force from the reinforcing member 11 can be efficiently transmitted to the H-section steel.

以上、添付図を参照しながら、本発明の実施の形態を説明したが、本発明の技術的範囲は、前述した実施の形態に左右されない。当業者であれば、特許請求の範囲に記載された技術的思想の範疇内において各種の変更例または修正例に想到し得ることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。 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.
