Description
本発明は、構造体を補強する補強部材が接合されるガセットプレートを固定するための固定部材及びこれを用いた構造体への補強部材の固定構造及びその固定方法に関するものである。 The present invention relates to a fixing member for fixing a gusset plate to which a reinforcing member that reinforces a structure is joined, and a fixing structure and fixing method for a reinforcing member to a structure using the fixing member.
従来、既存の構造体に対して、ブレース等の補強部材を配置することで耐震補強を行う方法が行われている。この際、溶接ではなく、柱に固定部材を用いてブレース等を固定する方法がある（例えば特許文献１）。 Conventionally, existing structures have been reinforced against earthquakes by placing reinforcing members such as braces. In this case, there is a method in which braces are fixed to columns using fixing members rather than welding (for example, Patent Document 1).
図１３は、一般的な補強部材固定構造１００を示す図である。構造体１１１は、柱と梁とからなる。柱と梁は、例えば、一対のフランジ１１３がウェブ１１５で接合されたＨ形鋼からなる。補強部材固定構造１００では、既存の構造体１１１に対して、補強部材１０７ａ、１０７ｂが新たに固定される。図示した例では、補強部材１０７ａは、柱と梁との間の対角線上に配置され、補強部材１０７ｂは、隣り合う柱同士を梁に略平行に配置される。 Figure 13 is a diagram showing a typical reinforcing member fixing structure 100. The structure 111 is made up of a column and a beam. The column and beam are made up of, for example, H-shaped steel with a pair of flanges 113 joined by a web 115. In the reinforcing member fixing structure 100, reinforcing members 107a and 107b are newly fixed to the existing structure 111. In the example shown, reinforcing member 107a is arranged diagonally between the column and the beam, and reinforcing member 107b is arranged between adjacent columns approximately parallel to the beam.
このような補強部材１０７ａ、１０７ｂを構造体１１１に固定するためには、固定部材１０１、１０３が用いられる。固定部材１０１は、ガセットプレート１０５が接合された部材である。ガセットプレート１０５は、補強部材１０７ａ、１０７ｂと接合可能である。 Fixing members 101 and 103 are used to fix the reinforcing members 107a and 107b to the structure 111. The fixing member 101 is a member to which the gusset plate 105 is joined. The gusset plate 105 can be joined to the reinforcing members 107a and 107b.
固定部材１０１と固定部材１０３は、柱のウェブ１１５の両側に配置され、ウェブ１１５を貫通するボルトで固定される。すなわち、固定部材１０１と固定部材１０３とでウェブ１１５を挟み込み、両者がボルトで固定される。 The fixing members 101 and 103 are disposed on either side of the column web 115 and are fixed with bolts that pass through the web 115. In other words, the fixing members 101 and 103 sandwich the web 115 and are fixed with bolts.
図１４は、固定部材１０１側から見た図である。固定部材１０１は、主に、固定板１０２と、固定板１０２に固定されるガセットプレート１０５と、ガセットプレート１０５の両側において、それぞれガセットプレート１０５と直交する方向に配置されるリブ１０９ａ、１０９ｂ等からなる。なお、固定用のボルト１１７は、リブ１０９ａ、１０９ｂの部位を避けて配置される。 Figure 14 is a view from the fixed member 101 side. The fixed member 101 mainly consists of a fixed plate 102, a gusset plate 105 fixed to the fixed plate 102, and ribs 109a, 109b arranged on both sides of the gusset plate 105 in a direction perpendicular to the gusset plate 105. The fixing bolt 117 is arranged to avoid the areas of the ribs 109a, 109b.
ガセットプレート１０５が接合された固定部材１０１は、ウェブ１１５の背面側から、固定部材１０３によって柱に固定される。この際、ガセットプレートが接合された固定部材１０１は、補強部材１０７ａ、１０７ｂからの引張力を受ける。このため、固定部材１０１は、これに耐えうるために、リブ１０９ａ、１０９ｂが固定板１０２に固定される。 The fixed member 101 to which the gusset plate 105 is joined is fixed to the column by the fixed member 103 from the back side of the web 115. At this time, the fixed member 101 to which the gusset plate is joined receives a tensile force from the reinforcing members 107a and 107b. Therefore, in order for the fixed member 101 to withstand this force, the ribs 109a and 109b are fixed to the fixed plate 102.
ここで、補強部材は、必ずしも構造体（柱）の中心に配置されるわけではない。このため、固定部材１０１において、ガセットプレート１０５の配置は、必ずしも固定板１０２の幅方向の中央ではなく、中心からずれた位置に配置される場合がある。また、補強部材の設置角度に応じて、使用されるガセットプレート１０５のサイズや形状が異なる場合がある。 The reinforcing member is not necessarily positioned at the center of the structure (column). For this reason, in the fixing member 101, the gusset plate 105 is not necessarily positioned at the center of the width of the fixing plate 102, but may be positioned at a position offset from the center. Also, the size and shape of the gusset plate 105 used may differ depending on the installation angle of the reinforcing member.
通常、ガセットプレート１０５とリブ１０９ａ、１０９ｂは、予め固定板１０２に溶接によって固定される。このため、補強部材の固定位置や種類に応じて、ガセットプレート１０５の固定位置（偏心位置）等が異なる、種々の固定部材１０１を準備する必要があった。 Normally, the gusset plate 105 and ribs 109a, 109b are fixed to the fixed plate 102 in advance by welding. For this reason, it was necessary to prepare various fixing members 101 with different fixing positions (eccentric positions) of the gusset plate 105 depending on the fixing position and type of the reinforcing member.
また、固定部材１０１は、通常、工場で製造されるが、ガセットプレート１０５の固定位置に応じて、リブ１０９ａ、１０９ｂの形状も変わることから、ガセットプレート１０５の偏心位置に応じた形状のリブ１０９ａ、１０９ｂ用の部材を準備する必要があった。このため、固定部材１０１を製造するための部材の種類が多く、完成した固定部材１０１も種々の形状を有するため、管理や保管の負担増となっていた。 In addition, the fixing member 101 is usually manufactured in a factory, but since the shape of the ribs 109a, 109b changes depending on the fixing position of the gusset plate 105, it was necessary to prepare parts for the ribs 109a, 109b with shapes that correspond to the eccentric position of the gusset plate 105. As a result, there are many types of parts for manufacturing the fixing member 101, and the completed fixing member 101 also has various shapes, which increases the burden of management and storage.
本発明は、このような問題に鑑みてなされたもので、種々の補強部材の設置位置に対応可能であり、効率よく構造体を補強することが可能な固定部材、及びこれを用いた構造体への補強部材の固定構造とその固定方法を提供することを目的とする。 The present invention was made in consideration of these problems, and aims to provide a fixing member that can be adapted to various installation positions of reinforcing members and can efficiently reinforce a structure, as well as a fixing structure and fixing method for a reinforcing member to a structure using the same.
前述した目的を達成するため、第１の発明は、構造体への補強部材の固定部材であって、ボルト孔を有する固定板と、前記固定板へ接合され、前記固定板の一方の方向に連続するリブと、を具備し、前記リブで区画された前記固定板の一方の側の、前記リブのいずれかの位置において、前記リブと略直交する方向に配置されるガセットプレートと、前記リブで区画された前記固定板の他方の側の前記リブのいずれかの位置に配置され、前記ガセットプレートからの応力を受けるための応力受け部材と、を具備し、前記固定板の他方の側において、一体化された前記応力受け部材が前記固定板及び前記リブに固定されており、前記リブの形成方向に対して、前記応力受け部材が前記固定板及び前記リブに固定されている範囲は、前記リブの厚みよりも幅広であり、前記応力受け部材の接合位置を含む所定の範囲において、前記固定板の一方の側に、前記応力受け部材とは別体で構成される前記ガセットプレートが接合され、前記ガセットプレートからの応力を受けることが可能であることを特徴とする固定部材である。 In order to achieve the above-mentioned object, the first invention is a fixing member for fixing a reinforcing member to a structure, comprising a fixing plate having a bolt hole, and a rib joined to the fixing plate and continuing in one direction of the fixing plate, a gusset plate arranged at any position of the rib on one side of the fixing plate partitioned by the rib, in a direction approximately perpendicular to the rib, and a stress receiving member arranged at any position of the rib on the other side of the fixing plate partitioned by the rib, for receiving stress from the gusset plate , wherein the integrated stress receiving member is fixed to the fixing plate and the rib on the other side of the fixing plate, the range in which the stress receiving member is fixed to the fixing plate and the rib in the direction of formation of the rib is wider than the thickness of the rib, and the gusset plate, which is constructed separately from the stress receiving member, is joined to one side of the fixing plate in a predetermined range including the joining position of the stress receiving member, and the fixing member is capable of receiving stress from the gusset plate .
前記リブの厚みをｔとすると、前記リブの形成方向に対して、前記応力受け部材が前記固定板及び前記リブに固定されている範囲は、１０ｔ以上の範囲であってもよい。When the thickness of the rib is t, the range in which the stress receiving member is fixed to the fixing plate and the rib in the direction in which the rib is formed may be a range of 10t or more.
第２の発明は、構造体への補強部材の固定部材であって、ボルト孔を有する固定板と、前記固定板へ接合され、前記固定板の一方の方向に連続するリブと、を具備し、前記リブで区画された前記固定板の一方の側の、前記リブのいずれかの位置において、前記リブと略直交する方向に配置されるガセットプレートと、前記リブで区画された前記固定板の他方の側の前記リブのいずれかの位置に配置され、前記ガセットプレートからの応力を受けるための応力受け部材と、を具備し、前記他方の側において、複数の箇所に、板状の前記応力受け部材が前記固定板及び前記リブに固定されており、前記応力受け部材の接合位置を含む所定の範囲において、前記固定板の一方の側に接合される前記ガセットプレートからの応力を受けることが可能であることを特徴とする固定部材である。 The second invention is a fixing member for fixing a reinforcing member to a structure, comprising a fixing plate having a bolt hole, and a rib joined to the fixing plate and continuing in one direction of the fixing plate, a gusset plate arranged at any position of the rib on one side of the fixing plate partitioned by the rib, in a direction approximately perpendicular to the rib, and a stress receiving member arranged at any position of the rib on the other side of the fixing plate partitioned by the rib, for receiving stress from the gusset plate, wherein on the other side, plate-shaped stress receiving members are fixed to the fixing plate and the rib at multiple locations, and the fixing member is capable of receiving stress from the gusset plate joined to one side of the fixing plate within a predetermined range including the joining position of the stress receiving member.
この場合、前記リブの厚みをｔとすると、前記リブの形成方向に対する前記ガセットプレートが接合される範囲は、前記応力受け部材の位置から前記リブの形成方向に対して１０ｔ以内の範囲であることが望ましい。 In this case, assuming that the thickness of the rib is t, it is desirable that the range in which the gusset plate is joined in the direction in which the rib is formed be within a range of 10t from the position of the stress receiving member in the direction in which the rib is formed .
前記リブの形成方向の中心位置に対して、前記ガセットプレートが偏心した位置に配置されていてもよい。 The gusset plate may be positioned eccentrically relative to the center position in the direction in which the rib is formed.
第１～第２の発明によれば、固定板に予め両端を繋ぐように連続するリブが固定されているため、ガセットプレートの配置等に応じて、異なるリブ用の部材を用意する必要がない。また、ガセットプレートの配置が決まる前にリブの固定を行うことで、ガセットプレートの配置に応じてリブを固定する必要がないため、リブが固定された固定板を、ガセットプレートの配置の種類によらず、共通化することができる。 According to the first and second inventions, since the continuous rib is fixed to the fixed plate in advance so as to connect both ends, there is no need to prepare different members for the rib depending on the arrangement of the gusset plates, etc. Also, since the rib is fixed before the arrangement of the gusset plates is decided, there is no need to fix the rib depending on the arrangement of the gusset plates, so the fixed plate to which the rib is fixed can be used in common regardless of the type of arrangement of the gusset plates.
また、リブを挟んでガセットプレートとは反対側に応力受け部材を配置することで、ガセットプレートの受ける応力を固定板に効率良く伝達し、十分な剛性を確保することができる。 In addition, by placing a stress-receiving member on the opposite side of the gusset plate across the rib, the stress received by the gusset plate can be efficiently transmitted to the fixed plate, ensuring sufficient rigidity.
なお、応力受け部材は、リブを挟んでガセットプレートと同一の位置に配置すればよいが、予め応力受け部材を固定板に固定してもよい。この場合には、応力受け部材が、リブの形成方向に対して所定の範囲でガセットプレートからの応力を受けられれば、その範囲のいずれかにガセットプレートを固定して使用することができる。 The stress-receiving member may be placed in the same position as the gusset plate, sandwiching the rib, but the stress-receiving member may also be fixed to the fixed plate in advance. In this case, if the stress-receiving member can receive stress from the gusset plate within a specified range in the direction in which the rib is formed, the gusset plate can be fixed anywhere within that range for use.
また、同様の効果は、複数の応力受け部材を配置しておき、それらの応力受け部材の固定された範囲内において、ガセットプレートを固定可能としてもよい。このように、ある程度の範囲において、応力を受けることが可能な形態で、予め応力受け部材を固定板に固定しておくことで、ガセットプレートの固定位置によらず、共通の部材として使用することができる。 The same effect can be achieved by arranging multiple stress receiving members and allowing the gusset plate to be fixed within the range in which these stress receiving members are fixed. In this way, by fixing the stress receiving members to the fixing plate in advance in a form that allows them to receive stress within a certain range, they can be used as a common member regardless of the fixed position of the gusset plate.
なお、複数の応力受け部材を固定する際には、応力受け部材の設置間隔をリブ厚みｔに対して、１０ｔ以下とすることで、応力受け部材同士の間のいずれの位置においても、ガセットプレートからの応力を受ける効果を期待することができる。 When multiple stress-receiving members are fixed, the installation interval between the stress-receiving members should be set to 10t or less relative to the rib thickness t, so that the effect of receiving stress from the gusset plate can be expected at any position between the stress-receiving members.
また、応力受け部材の幅を広くして、応力受け範囲を広くしておくことで、そのいずれかの位置にガセットプレートを固定して、固定部材として使用することができる。 In addition, by widening the width of the stress-receiving member and widening the stress-receiving range, a gusset plate can be fixed to any position and used as a fixing member.
この際、ガセットプレートは、固定板の幅方向の中心から偏心した位置に固定することができる。 In this case, the gusset plate can be fixed at a position eccentric to the widthwise center of the fixed plate.
第３の発明は、第１の発明又は第２の発明にかかる固定部材を用いた構造体への補強部材の固定構造であって、前記構造体の一方の側に配置され、補強部材が固定される前記固定部材と、前記構造体の他方の側に配置され、前記構造体を挟み込んで前記固定部材とボルトで固定される他の固定部材と、を具備する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。 The third invention is a structure for fixing a reinforcing member to a structure using the fixing member of the first or second invention , characterized in that it comprises a fixing member that is arranged on one side of the structure and to which the reinforcing member is fixed, and another fixing member that is arranged on the other side of the structure and is fixed to the fixing member with a bolt, sandwiching the structure.
第３の発明によれば、補強部材の設置位置に応じて、効率良く固定部材を構造体へ設置することができる。 According to the third aspect of the present invention, the fixing member can be efficiently installed on the structure in accordance with the installation position of the reinforcing member.
第４の発明は、第１の発明又は第２の発明にかかる固定部材を用いた構造体への補強部材の施工方法であって、前記固定板の一方の側の前記範囲内における所定の位置に、前記ガセットプレートを接合する工程と、前記構造体の一方の側に前記固定部材を配置するとともに、前記構造体の他方の側に、他の固定部材を配置し、前記固定部材と前記他の固定部材とで前記構造体を挟み込んで固定する工程と、前記ガセットプレートに補強部材を固定する工程と、を具備することを特徴とする構造体への補強部材の固定方法である。 A fourth invention is a method of installing a reinforcing member to a structure using the fixing member of the first or second invention , comprising the steps of joining the gusset plate to a predetermined position within the range on one side of the fixing plate, placing the fixing member on one side of the structure and placing another fixing member on the other side of the structure, and sandwiching and fixing the structure between the fixing member and the other fixing member, and fixing a reinforcing member to the gusset plate.
第４の発明によれば、ガセットプレートの固定位置によらず予め応力受け部材を固定しておくため、ガセットプレートの固定位置によらず、共通の部材として使用することができる。 According to the fourth invention, the stress-receiving member is fixed in advance regardless of the fixing position of the gusset plate, so it can be used as a common member regardless of the fixing position of the gusset plate.
なお、第３～第４の発明において、前記他の固定部材が、前記固定部材の構成を有し、前記構造体の両側に、前記固定部材が配置されて前記構造体が挟み込まれてもよい。この場合、他の固定部材が、固定部材の構成を有するとは、必ずしも同一の形状であることを意味するのではなく、構造体の両側配置される固定部材が、異なる形状であってもよい。 In the third and fourth inventions, the other fixing members may have the configuration of the fixing members, and the fixing members may be disposed on both sides of the structure to sandwich the structure. In this case, the other fixing members having the configuration of the fixing members do not necessarily mean that they have the same shape, and the fixing members disposed on both sides of the structure may have different shapes.
本発明によれば、種々の補強部材の設置位置に対応可能であり、効率よく構造体を補強することが可能な固定部材、及びこれを用いた構造体への補強部材の固定構造とその固定方法を提供することができる。 The present invention provides a fixing member that can be used to install various reinforcing members and efficiently reinforce a structure, as well as a fixing structure and method for fixing a reinforcing member to a structure using the fixing member.
（固定部材１）
以下、本発明の実施の形態にかかる固定部材１について説明する。図１は、固定部材１の分解斜視図、図２は、固定部材１の斜視図である。固定部材１は、主に、固定板３、リブ７、ガセットプレート９、応力受け部材１１等からなる。固定部材１は、図１３に示した固定部材１０１と同様に、他の固定部材１０３と共に用いられ、補強部材を構造体へ固定するための部材である。
(Fixing member 1)
A fixing member 1 according to an embodiment of the present invention will be described below. Fig. 1 is an exploded perspective view of the fixing member 1, and Fig. 2 is a perspective view of the fixing member 1. The fixing member 1 mainly comprises a fixing plate 3, a rib 7, a gusset plate 9, a stress receiving member 11, etc. The fixing member 1, like the fixing member 101 shown in Fig. 13, is used together with another fixing member 103, and is a member for fixing a reinforcing member to a structure.
固定部材１は、例えば鋼製であり、略矩形の固定板３に対して、リブ７が溶接等によって接合される。リブ７は、固定板３の一方の方向（例えば、固定板３の一方の辺に略平行な方向）に、略端から端まで、固定板３の両端部を繋ぐように連続して配置される。なお、リブ７は、完全に端から端までなくてもよい。また、固定板３の四隅近傍には、ボルト孔５が形成される。ボルト孔５を貫通するボルトによって、他の固定部材１０３と共に構造体へ固定部材１を固定することができる。 The fixing member 1 is made of steel, for example, and the ribs 7 are joined to the substantially rectangular fixing plate 3 by welding or the like. The ribs 7 are continuously arranged in one direction of the fixing plate 3 (for example, in a direction substantially parallel to one side of the fixing plate 3) from end to end, connecting both ends of the fixing plate 3. The ribs 7 do not have to be completely end to end. In addition, bolt holes 5 are formed near the four corners of the fixing plate 3. The fixing member 1 can be fixed to the structure together with the other fixing members 103 by bolts that pass through the bolt holes 5.
リブ７で区画された固定板３の一方の側には、ガセットプレート９が固定される。ガセットプレート９は、補強部材が固定される固定部を有する。また、リブ７で区画された固定板３の他方の側には、応力受け部材１１が固定される。応力受け部材１１は、ガセットプレート９からの応力を受けるための部材である。ガセットプレート９及び応力受け部材１１は、共に板状部材であり、リブ７に対して略直交する向きに配置される。なお、図２に示すように、ガセットプレート９と応力受け部材１１とは、リブ７を挟んで略同一の位置となるように固定されることが望ましい。 A gusset plate 9 is fixed to one side of the fixed plate 3 defined by the rib 7. The gusset plate 9 has a fixing portion to which a reinforcing member is fixed. A stress receiving member 11 is fixed to the other side of the fixed plate 3 defined by the rib 7. The stress receiving member 11 is a member for receiving stress from the gusset plate 9. The gusset plate 9 and the stress receiving member 11 are both plate-shaped members, and are arranged in a direction substantially perpendicular to the rib 7. As shown in FIG. 2, it is desirable that the gusset plate 9 and the stress receiving member 11 are fixed so that they are in substantially the same position across the rib 7.
ここで、前述した従来の固定部材１０１（図１４）では、ガセットプレート１０５が固定板１０２の端から端まで連続して配置され、ガセットプレート１０５の両側にリブ１０９ａ、１０９ｂが分割して配置された。一方、本実施形態では、リブ７が一体で構成され、リブ７を挟んで一方の側にガセットプレート９が固定され、リブ７を挟んで他方の側に応力受け部材１１が固定される。すなわち、固定部材１では、リブ７が分割されるのではなく、従来のガセットプレート１０５を、ガセットプレート９と応力受け部材１１とに分割した形態となる。このようにすることで、ガセットプレート９の配置によらず、同一のリブ付き固定板を共通して使用することができる。 Here, in the conventional fixing member 101 (FIG. 14) described above, the gusset plate 105 is arranged continuously from one end of the fixing plate 102 to the other end, and the ribs 109a, 109b are arranged separately on both sides of the gusset plate 105. On the other hand, in this embodiment, the rib 7 is integrally formed, and the gusset plate 9 is fixed to one side of the rib 7, and the stress receiving member 11 is fixed to the other side of the rib 7. That is, in the fixing member 1, the rib 7 is not divided, but the conventional gusset plate 105 is divided into the gusset plate 9 and the stress receiving member 11. In this way, the same ribbed fixing plate can be used regardless of the arrangement of the gusset plate 9.
例えば、図１のように、ガセットプレート９と応力受け部材１１とを、固定板３等へ接合せずに分離した状態としておけば、ガセットプレート９の配置が決まってから、ガセットプレート９と応力受け部材１１とを溶接等によって固定板３及びリブ７へ接合することができえる。すなわち、ガセットプレート９及び応力受け部材１１を、リブ７のいずれかの位置に配置して接合することができる。 For example, as shown in FIG. 1, if the gusset plate 9 and the stress receiving member 11 are left separate and not joined to the fixed plate 3, etc., then once the position of the gusset plate 9 has been determined, the gusset plate 9 and the stress receiving member 11 can be joined to the fixed plate 3 and the rib 7 by welding or the like. In other words, the gusset plate 9 and the stress receiving member 11 can be joined by positioning them at any position on the rib 7.
図３（ａ）と図３（ｂ）は、ガセットプレート９の配置の違いを示す図である。ガセットプレート９は、リブ７の形成方向（固定部材１の幅方向であって、図中左右方向）の中心位置に対して、偏心した位置に配置されるが、リブ７が固定された固定板３は、共通部材である。このように、固定板３に対して、ガセットプレート９の配置が異なる場合でも、リブ７が接合された固定板３は、共通して使用することができる。このため、ガセットプレート９の配置ごとに異なる部材を用いる必要がない。 Figures 3(a) and 3(b) show different arrangements of the gusset plate 9. The gusset plate 9 is arranged in an eccentric position relative to the center position in the direction in which the rib 7 is formed (the width direction of the fixed member 1, which is the left-right direction in the figure), but the fixed plate 3 to which the rib 7 is fixed is a common member. In this way, even if the arrangement of the gusset plate 9 differs relative to the fixed plate 3, the fixed plate 3 to which the rib 7 is joined can be used in common. For this reason, it is not necessary to use different members for each arrangement of the gusset plate 9.
なお、リブ７は、固定板３の補強の効果を考慮すれば、固定板３の幅方向に直交する方向（図中上下方向）の略中心に配置されることが望ましいが、リブ７を固定板３の中心からずらしてもよい。例えば、ガセットプレート９が配置される側を広くしてもよく、応力受け部材１１が配置される側を広くしてもよい。なお、応力受け部材１１は、リブ７から、固定板３の端まで配置され、固定板３に接合されることが望ましい。 In consideration of the reinforcing effect of the fixed plate 3, it is desirable to place the rib 7 approximately in the center in the direction perpendicular to the width direction of the fixed plate 3 (the vertical direction in the figure), but the rib 7 may be offset from the center of the fixed plate 3. For example, the side where the gusset plate 9 is placed may be made wider, or the side where the stress receiving member 11 is placed may be made wider. In addition, it is desirable that the stress receiving member 11 is placed from the rib 7 to the end of the fixed plate 3 and joined to the fixed plate 3.
次に、固定部材１を用いた構造体への補強部材の施工方法について説明する。まず、図１に示した状態から、固定板３の一方の側の所定の位置に、ガセットプレート９を接合するとともに、固定板３の他方の側において、ガセットプレート９に対応する位置に、応力受け部材１１を接合する。次に、構造体（例えばＨ形鋼のウェブ）の一方の側に固定部材１を配置するとともに、構造体の他方の側に、他の固定部材（例えば、図１３の固定部材１０３）を配置し、固定部材１と他の固定部材１０３とで構造体を挟み込んで、両者をボルトで固定する。その後、ガセットプレート９に補強部材を固定することで、構造体への補強部材の固定構造を得ることができる。 Next, a method of installing a reinforcing member on a structure using the fixing member 1 will be described. First, starting from the state shown in FIG. 1, a gusset plate 9 is joined to a predetermined position on one side of the fixing plate 3, and a stress receiving member 11 is joined to a position corresponding to the gusset plate 9 on the other side of the fixing plate 3. Next, the fixing member 1 is placed on one side of the structure (e.g., the web of the H-shaped steel), and another fixing member (e.g., the fixing member 103 in FIG. 13) is placed on the other side of the structure, and the structure is sandwiched between the fixing member 1 and the other fixing member 103 and fixed with bolts. After that, the reinforcing member is fixed to the gusset plate 9, thereby obtaining a fixed structure for the reinforcing member on the structure.
本実施形態によれば、ガセットプレート９の配置によらず、部材を共通化することができる。例えば、一般的な設計思想からすれば、補強部材からの力が直接にかかるガセットプレートを一体で構成し、この応力を受ける固定板の補強のためのリブを、ガセットプレートの両側に分割して配置する方が、応力的に有利であると考えられる（図１４の固定部材１０１参照）。しかし、このようにすると、前述したように、ガセットプレートの配置に応じて異なる形状のリブを準備して、ガセットプレート接合後に、リブを固定する必要がある。 According to this embodiment, the components can be standardized regardless of the arrangement of the gusset plate 9. For example, from the perspective of general design concepts, it is considered advantageous in terms of stress to construct the gusset plate, which is directly subjected to the force from the reinforcing member, as an integral unit, and to arrange the ribs for reinforcing the fixed plate that receives this stress separately on both sides of the gusset plate (see fixing member 101 in FIG. 14). However, if this is done, as mentioned above, it is necessary to prepare ribs of different shapes according to the arrangement of the gusset plate and to fix the ribs after joining the gusset plate.
一方、ガセットプレート９と応力受け部材１１とが、確実に固定板３とリブ７とに一体で接合されていれば、リブ７を挟んでガセットプレート９と応力受け部材１１とに分割しても、十分に応力を固定板３の全体で受けることができる。本実施形態は、このような発想の転換により、ガセットプレート９の配置の自由度を高め、部材の共通化を可能にしたものである。 On the other hand, if the gusset plate 9 and the stress receiving member 11 are securely joined integrally to the fixed plate 3 and the rib 7, the stress can be fully received by the entire fixed plate 3 even if the gusset plate 9 and the stress receiving member 11 are separated by the rib 7. This change in concept in the present embodiment increases the freedom of arrangement of the gusset plate 9 and enables the use of common components.
（固定部材１ａ）
次に、他の実施形態について説明する。図４は、固定部材１ａを示す斜視図であり、図５（ａ）は、固定部材１ａの平面図である。なお、以下の説明において、固定部材１と同一の機能を奏する構成については、図１～図３と同一の符号を付し、重複する説明を省略する。
(Fixing member 1a)
Next, another embodiment will be described. Fig. 4 is a perspective view showing the fixing member 1a, and Fig. 5(a) is a plan view of the fixing member 1a. In the following description, components having the same functions as the fixing member 1 are given the same reference numerals as in Figs. 1 to 3, and duplicated descriptions will be omitted.
固定部材１ａは、固定部材１と略同様の構造であるが、複数の応力受け部材１１が間隔をあけて配置される点で異なる。固定部材１では、ガセットプレート９と応力受け部材１１とをリブ７を挟んで略同一の位置になるように固定したが、固定部材１ａでは、ガセットプレート９と応力受け部材１１とを、リブ７を挟んで一直線上に配置する必要はない。 Fixed member 1a has a structure similar to fixed member 1, but differs in that multiple stress receiving members 11 are arranged at intervals. In fixed member 1, the gusset plate 9 and the stress receiving member 11 are fixed in approximately the same position with the rib 7 in between, but in fixed member 1a, the gusset plate 9 and the stress receiving member 11 do not need to be arranged in a straight line with the rib 7 in between.
ここで、図５（ａ）に示すように、リブ７の厚みをｔとする。この際、応力解析の結果より、応力受け部材１１の中心線同士の間隔（図中Ａ）を１０ｔ以下とすることで、この応力受け部材１１同士の間の範囲であれば、いずれの範囲であっても、ガセットプレート９からの応力を十分に受けることが可能である。すなわち、リブ７の一方の側に配置されるガセットプレート９は、リブ７の他方の側に固定される複数の応力受け部材１１同士の間の任意の位置に固定することができる。 As shown in FIG. 5(a), the thickness of the rib 7 is t. In this case, the results of stress analysis show that by setting the distance between the centerlines of the stress-receiving members 11 (A in the figure) to 10t or less, it is possible for any range between these stress-receiving members 11 to fully receive the stress from the gusset plate 9. In other words, the gusset plate 9 arranged on one side of the rib 7 can be fixed at any position between the multiple stress-receiving members 11 fixed to the other side of the rib 7.
また、さらに、応力受け部材１１とボルト孔５との中心線同士の間隔（図中Ｂ）を１０ｔ以下とすることで、この応力受け部材１１の外側であって、応力受け部材１１からボルト孔５の範囲であれば、いずれの範囲であっても、ガセットプレート９からの応力を受けることが可能である。すなわち、リブ７の一方の側に配置されるガセットプレート９は、リブ７の他方の側に固定される応力受け部材１１とボルト孔５の間の任意の位置に固定することができる。 Furthermore, by setting the distance (B in the figure) between the center lines of the stress receiving member 11 and the bolt hole 5 to 10t or less, it is possible for any area outside the stress receiving member 11, within the range from the stress receiving member 11 to the bolt hole 5, to receive stress from the gusset plate 9. In other words, the gusset plate 9 arranged on one side of the rib 7 can be fixed at any position between the stress receiving member 11 fixed to the other side of the rib 7 and the bolt hole 5.
このように、複数の箇所に板状の応力受け部材１１を固定板３及びリブ７に固定しておくことで、応力受け部材１１の接合位置を含め、リブ７の形成方向（図５（ａ）の左右方向）に対して所定の範囲（応力受け部材１１の位置から１０ｔ以内の範囲であって、図中Ｃの範囲（ボルト孔５と干渉する部位を除く））にガセットプレート９を固定して使用することができる。 In this way, by fixing the plate-shaped stress receiving members 11 to the fixed plate 3 and the rib 7 at multiple locations, the gusset plate 9 can be fixed and used within a predetermined range (within 10t from the position of the stress receiving members 11, and within range C in the figure (excluding the area interfering with the bolt hole 5)) in the formation direction of the rib 7 (left and right direction in Figure 5(a)), including the joining position of the stress receiving members 11.
また、図５（ａ）においては、応力受け部材１１が二つ配置される例を示したが、これには限られない。応力受け部材１１を３カ所以上配置してもよい。この場合でも、それぞれの応力受け部材１１同士の間隔を１０ｔ以下とし、外側の応力受け部材１１とボルト孔５との間隔を１０ｔ以下とすることで、任意の位置にガセットプレート９を接合して使用することができる。 In addition, while FIG. 5(a) shows an example in which two stress receiving members 11 are arranged, this is not limiting. Three or more stress receiving members 11 may be arranged. Even in this case, the gusset plate 9 can be joined and used at any position by making the distance between each stress receiving member 11 10t or less and the distance between the outer stress receiving member 11 and the bolt hole 5 10t or less.
また、図５（ａ）においては、ガセットプレート９が接合された状態であるが、ガセットプレート９が固定されていない状態で、リブ７と応力受け部材１１のみを固定板３に固定しておいてもよい。例えば、固定部材１ａにおいては、リブ７の一方の側にガセットプレート９が固定される前に、リブ７の他方の側における複数の応力受け部材１１が、予め固定板３及びリブ７に接合されてもよい。この場合には、補強部材の配置に応じて、前述した範囲内の任意の位置にガセットプレート９を接合して使用することができる。すなわち、リブ７と応力受け部材１１が固定された固定板３を共通して使用することができる。 In addition, while FIG. 5(a) shows the gusset plate 9 joined, it is also possible to fix only the rib 7 and the stress receiving member 11 to the fixed plate 3 without the gusset plate 9 being fixed. For example, in the fixed member 1a, before the gusset plate 9 is fixed to one side of the rib 7, multiple stress receiving members 11 on the other side of the rib 7 may be joined to the fixed plate 3 and the rib 7 in advance. In this case, the gusset plate 9 can be used by joining it to any position within the aforementioned range depending on the arrangement of the reinforcing member. In other words, the fixed plate 3 to which the rib 7 and the stress receiving member 11 are fixed can be used in common.
次に、ガセットプレート９のみが接合されていない固定部材１ａを用いた構造体への補強部材の施工方法について説明する。まず、固定板３の一方の側の所定の位置に、ガセットプレート９を接合する。次に、構造体（例えばＨ形鋼のウェブ）の一方の側に固定部材１を配置するとともに、構造体の他方の側に、他の固定部材（例えば、図１３の固定部材１０３）を配置し、固定部材１と他の固定部材１０３とで構造体を挟み込んで、両者をボルトで固定する。その後、ガセットプレート９に補強部材を固定することで、構造体への補強部材の固定構造を得ることができる。 Next, a method of installing a reinforcing member on a structure using a fixing member 1a to which only the gusset plate 9 is not joined will be described. First, the gusset plate 9 is joined to a predetermined position on one side of the fixing plate 3. Next, the fixing member 1 is placed on one side of the structure (e.g., the web of the H-shaped steel), and another fixing member (e.g., fixing member 103 in FIG. 13) is placed on the other side of the structure, and the structure is sandwiched between the fixing member 1 and the other fixing member 103 and fixed with bolts. After that, the reinforcing member is fixed to the gusset plate 9, thereby obtaining a fixed structure for the reinforcing member on the structure.
なお、以下の各実施形態でも、ガセットプレート９が接合されていない状態で取り扱い、補強部材の配置に合わせて、最後にガセットプレート９のみを接合して使用することができる。 In addition, in each of the following embodiments, the gusset plate 9 can be handled in an unjoined state, and then only the gusset plate 9 can be joined at the end to match the arrangement of the reinforcing member.
（固定部材１ｂ）
図５（ｂ）は、固定部材１ｂを示す図である。固定部材１ｂは固定部材１ａと略同様であるが、応力受け部材１１の配置が異なる。前述した固定部材１ａは、固定板３の四隅近傍にボルト孔５が配置され、応力受け部材１１は、ボルト孔５よりも内側に配置されたが、固定部材１ｂでは、応力受け部材１１の一部がボルト孔５の外側に配置される。図示した例では、応力受け部材１１は、リブ７の形成方向の略中央と両端部近傍に配置される。
(Fixing member 1b)
5B is a diagram showing a fixing member 1b. The fixing member 1b is substantially similar to the fixing member 1a, but the arrangement of the stress receiving members 11 is different. In the fixing member 1a described above, the bolt holes 5 are arranged near the four corners of the fixing plate 3, and the stress receiving members 11 are arranged inside the bolt holes 5, but in the fixing member 1b, a part of the stress receiving members 11 is arranged outside the bolt holes 5. In the illustrated example, the stress receiving members 11 are arranged approximately in the center in the formation direction of the ribs 7 and near both ends.
この場合でも、応力受け部材１１からボルト孔５までの間隔（図中Ｄ又は図中Ｅ）が１０ｔ以下であれば、応力受け部材１１の接合位置を含め、リブ７の形成方向に対して所定の範囲（応力受け部材１１の位置から１０ｔ以内の範囲であって、図中Ｆの範囲（ボルト孔５と干渉する部位を除く））にガセットプレート９を固定して使用することができる。なお、本実施形態でも、応力受け部材１１の配置数は図示した例には限られない。 Even in this case, if the distance from the stress receiving member 11 to the bolt hole 5 (D or E in the figure) is 10t or less, the gusset plate 9 can be fixed and used within a predetermined range (a range within 10t from the position of the stress receiving member 11, and excluding the area interfering with the bolt hole 5) in the formation direction of the rib 7, including the joining position of the stress receiving member 11. Note that even in this embodiment, the number of stress receiving members 11 arranged is not limited to the example shown.
（固定部材１ｃ）
図６は、固定部材１ｃを示す斜視図であり、図７は、固定部材１ｃの平面図である。固定部材１ｃは固定部材１ａ等と略同様であるが、板状の応力受け部材１１が複数枚互いに離間して配置されるのではなく、リブ７の形成方向に対して、所定の範囲にわたって応力受け部材１１ａが配置される。
(Fixing member 1c)
Fig. 6 is a perspective view showing the fixing member 1c, and Fig. 7 is a plan view of the fixing member 1c. The fixing member 1c is substantially similar to the fixing member 1a, etc., but instead of multiple plate-shaped stress receiving members 11 being arranged spaced apart from each other, stress receiving members 11a are arranged over a predetermined range in the direction in which the ribs 7 are formed.
応力受け部材１１ａは、例えば一対の板状の部材（応力受け部材１１と同様の部材）と、これを連結する連結部からなる。応力受け部材１１ａは、リブ７の形成方向に対して所定の範囲において、リブ７及び固定板３に連続して接合される。すなわち、応力受け部材１１ａは、少なくとも、リブ７の厚みｔよりも十分に幅広であり、例えば、応力受け部材１１ａの幅（図中Ｇ）は、１０ｔ以上の範囲に配置される。 The stress receiving member 11a is composed of, for example, a pair of plate-shaped members (similar members to the stress receiving member 11) and a connecting portion that connects them. The stress receiving member 11a is continuously joined to the rib 7 and the fixed plate 3 within a predetermined range in the direction in which the rib 7 is formed. In other words, the stress receiving member 11a is at least sufficiently wider than the thickness t of the rib 7, and for example, the width of the stress receiving member 11a (G in the figure) is set in a range of 10t or more.
この場合でも、応力受け部材１１ａからボルト孔５までの間隔（図中Ｈ）が１０ｔ以下であれば、応力受け部材１１ａの接合位置を含め、リブ７の形成方向に対して所定の範囲（一方のボルト孔５から他方のボルト孔５までの間（ボルト孔５と干渉する部位を除く））にガセットプレート９を固定して使用することができる。 Even in this case, if the distance (H in the figure) between the stress receiving member 11a and the bolt hole 5 is 10t or less, the gusset plate 9 can be fixed and used within a predetermined range (between one bolt hole 5 and the other bolt hole 5 (excluding the area interfering with the bolt hole 5)) in the formation direction of the rib 7, including the joining position of the stress receiving member 11a.
なお、固定部材１ｃも、固定部材１ａ等と同様にガセットプレート９のみを接合しない状態で、他の部材を共通化することができる。このため、使用場所に応じて、ガセットプレート９を所定の場所に接合して使用することができる。また、応力受け部材１１ａが幅広であるため、複数の板状の応力受け部材１１を離間して配置するよりも、より確実に広範囲にわたってガセットプレート９からの応力を受けることができる。 As with the fixing member 1a, the fixing member 1c can be used with other components in common without joining only the gusset plate 9. Therefore, the gusset plate 9 can be joined to a specified location depending on the place of use. In addition, since the stress receiving member 11a is wide, it can more reliably receive stress from the gusset plate 9 over a wider area than if multiple plate-shaped stress receiving members 11 were spaced apart.
なお、応力受け部材１１ａは、板状の各部を溶接等で接合して一体化してもよく、又は、応力受け部材１１ａを鋳物などによって一体で構成してもよい。また、さらに、ガセットプレート９を除く部位全体を鋳物としてもよい。 The stress receiving member 11a may be integrated by joining each plate-like portion by welding or the like, or the stress receiving member 11a may be integrally formed by casting or the like. Furthermore, the entire portion except for the gusset plate 9 may be made of casting.
（固定部材１ｄ）
図８（ａ）は、固定部材１ｄを示す斜視図である。固定部材１ｄは固定部材１ｃと略同様であるが、応力受け部材１１ｂが用いられる点で異なる。応力受け部材１１ｂは、リブ７の所定の範囲に接合される。応力受け部材１１ｂは、リブ７に連続する上面と側面とを有し、応力受け部材１１ｂの上面及び側面は、リブ７から離れるにつれて徐々に高さが低く、幅が狭くなるように形成される。
(Fixing member 1d)
8(a) is a perspective view showing a fixing member 1d. The fixing member 1d is substantially similar to the fixing member 1c, but differs in that a stress receiving member 11b is used. The stress receiving member 11b is joined to a predetermined area of the rib 7. The stress receiving member 11b has an upper surface and a side surface that are continuous with the rib 7, and the upper surface and the side surface of the stress receiving member 11b are formed so that the height and the width gradually decrease with increasing distance from the rib 7.
この場合でも、固定部材１ｃと同様の効果を得ることができる。なお、応力受け部材１１ｂは、中実であっても中空であってもよい。中実の場合には例えば鋳造等で形成され、中空の場合には、例えば板部材を接合することで形成される。なお、以下の各実施形態でも同様である。 Even in this case, the same effect as the fixed member 1c can be obtained. The stress receiving member 11b may be solid or hollow. If it is solid, it is formed by casting, for example, and if it is hollow, it is formed by joining plate members, for example. The same applies to each of the following embodiments.
（固定部材１ｅ）
図８（ｂ）は、固定部材１ｅを示す斜視図である。固定部材１ｅは固定部材１ｄと略同様であるが、応力受け部材１１ｃが用いられる点で異なる。応力受け部材１１ｃは、リブ７の所定の範囲に接合される。応力受け部材１１ｃは、リブ７に連続する上面と側面とを有し、応力受け部材１１ｃの上面及び側面は、リブ７から離れるにつれて、幅は略一定のまま、徐々に高さが低くなるように形成される。この場合でも、固定部材１ｄと同様の効果を得ることができる。
(Fixed member 1e)
8B is a perspective view showing the fixing member 1e. The fixing member 1e is substantially similar to the fixing member 1d, but differs in that a stress receiving member 11c is used. The stress receiving member 11c is joined to a predetermined area of the rib 7. The stress receiving member 11c has an upper surface and a side surface that are continuous with the rib 7, and the upper surface and the side surface of the stress receiving member 11c are formed so that the height gradually decreases with increasing distance from the rib 7 while the width remains substantially constant. Even in this case, the same effect as the fixing member 1d can be obtained.
（固定部材１ｆ）
図９（ａ）は、固定部材１ｆを示す斜視図である。固定部材１ｆは固定部材１ｄ等と略同様であるが、応力受け部材１１ｄが用いられる点で異なる。応力受け部材１１ｄは、リブ７の所定の範囲に接合される。応力受け部材１１ｄは、リブ７に連続する上面と側面とを有し、応力受け部材１１ｄの上面及び側面は、リブ７から離れるにつれて、高さは略一定のまま、円弧状に徐々に幅が狭くなるように形成される。この場合でも、固定部材１ｄ等と同様の効果を得ることができる。
(Fixing member 1f)
9A is a perspective view showing a fixing member 1f. The fixing member 1f is substantially similar to the fixing member 1d, etc., but differs in that a stress receiving member 11d is used. The stress receiving member 11d is joined to a predetermined area of the rib 7. The stress receiving member 11d has an upper surface and a side surface that are continuous with the rib 7, and the upper surface and the side surface of the stress receiving member 11d are formed so that the width gradually narrows in an arc shape while the height remains substantially constant as the stress receiving member 11d moves away from the rib 7. Even in this case, the same effect as the fixing member 1d, etc. can be obtained.
（固定部材１ｇ）
図９（ｂ）は、固定部材１ｇを示す斜視図である。固定部材１ｇは固定部材１ｄ等と略同様であるが、応力受け部材１１ｅが用いられる点で異なる。応力受け部材１１ｅは、リブ７の所定の範囲に接合される。応力受け部材１１ｅは、リブ７に連続する上面と側面とを有し、応力受け部材１１ｅの上面及び側面は、リブ７から離れるにつれて、幅は略一定のまま、徐々に高さが低くなるように形成される。さらに、リブ７から離れた側の固定板３の端部近傍は幅方向の略中央部が円弧状に切り欠か枯れた形態である。すなわち、応力受け部材１１ｃに対して、リブから離れた部位の中央部が切りかかれた形態である。この場合でも、固定部材１ｄ等と同様の効果を得ることができる。
(Fixing member 1g)
FIG. 9B is a perspective view showing the fixing member 1g. The fixing member 1g is substantially similar to the fixing member 1d, etc., but differs in that a stress receiving member 11e is used. The stress receiving member 11e is joined to a predetermined range of the rib 7. The stress receiving member 11e has an upper surface and a side surface that are continuous with the rib 7, and the upper surface and the side surface of the stress receiving member 11e are formed so that the height gradually decreases as the distance from the rib 7 increases while the width remains substantially constant. Furthermore, the vicinity of the end of the fixing plate 3 on the side away from the rib 7 is cut or dried in a circular arc shape at the approximately central portion in the width direction. That is, the central portion of the part away from the rib is cut out with respect to the stress receiving member 11c. Even in this case, the same effect as the fixing member 1d, etc. can be obtained.
（固定部材１ｈ）
図１０（ａ）は、固定部材１ｈを示す斜視図である。固定部材１ｈは固定部材１ｄ等と略同様であるが、応力受け部材１１ｆが用いられる点で異なる。応力受け部材１１ｆは、リブ７の所定の範囲に接合される。応力受け部材１１ｆは、リブ７に連続する上面と側面とを有し、応力受け部材１１ｆの上面及び側面は、リブ７から離れるにつれて、所定の範囲では高さは略一定のまま、徐々に幅が狭くなるように形成され、さらにその後方で固定板３の端部までの間は、高さ方向も幅方向も段差を介して、高さが徐々に低くなり、幅が徐々に狭くなるように形成される。この場合でも、固定部材１ｄ等と同様の効果を得ることができる。
(Fixing member 1h)
10(a) is a perspective view showing the fixing member 1h. The fixing member 1h is substantially similar to the fixing member 1d, etc., but differs in that a stress receiving member 11f is used. The stress receiving member 11f is joined to a predetermined range of the rib 7. The stress receiving member 11f has an upper surface and a side surface that are continuous with the rib 7, and the upper surface and the side surface of the stress receiving member 11f are formed so that the height remains substantially constant in a predetermined range and the width gradually narrows as it moves away from the rib 7, and furthermore, from the rear of the stress receiving member 11f to the end of the fixing plate 3, the height gradually decreases and the width gradually narrows through steps in both the height direction and the width direction. Even in this case, the same effect as the fixing member 1d, etc. can be obtained.
（固定部材１ｉ）
図１０（ｂ）は、固定部材１ｉを示す斜視図である。固定部材１ｉは固定部材１ｄ等と略同様であるが、応力受け部材１１ｇが用いられる点で異なる。応力受け部材１１ｇは、リブ７の所定の範囲に接合される。応力受け部材１１ｇは、リブ７の背面（ガセットプレートとは逆方向）において、上面と側面とを有し、リブ７から離れるにつれて、リブ７に対して段差を介して、リブ７から離れるにつれて、幅は略一定のまま、徐々に高さが低くなるように形成される。即ち、前述した応力受け部材１１ｃの高さを低くし、長さ（リブ７の形成方向に略直交し、リブ７から固定板３の端部方向に向かう長さ）が短い。この場合でも、固定部材１ｄ等と同様の効果を得ることができる。
(Fixed member 1i)
FIG. 10B is a perspective view showing the fixing member 1i. The fixing member 1i is substantially similar to the fixing member 1d, etc., but differs in that a stress receiving member 11g is used. The stress receiving member 11g is joined to a predetermined range of the rib 7. The stress receiving member 11g has an upper surface and a side surface on the back surface of the rib 7 (opposite side to the gusset plate), and is formed so that the height gradually decreases as it moves away from the rib 7, with a step between the rib 7 and the rib 7, while the width remains substantially constant. That is, the height of the above-mentioned stress receiving member 11c is reduced, and the length (the length from the rib 7 toward the end of the fixing plate 3, substantially perpendicular to the formation direction of the rib 7) is short. Even in this case, the same effect as the fixing member 1d, etc. can be obtained.
（固定部材１ｊ）
図１１（ａ）は、固定部材１ｊを示す斜視図である。固定部材１ｊは固定部材１ｄ等と略同様であるが、応力受け部材１１ｈが用いられる点で異なる。応力受け部材１１ｈは、板状であり、リブ７の所定の範囲に接合される。応力受け部材１１ｈは、リブ７の背面（ガセットプレートとは逆方向）において、リブ７の上端部近傍から、固定板３の端部に向かって、リブ７から離れるにつれて徐々に高さが低くなるように形成される。この場合でも、固定部材１ｄ等と同様の効果を得ることができる。
(Fixed member 1j)
11(a) is a perspective view showing a fixing member 1j. The fixing member 1j is substantially similar to the fixing member 1d, etc., but differs in that a stress receiving member 11h is used. The stress receiving member 11h is plate-shaped and is joined to a predetermined area of the rib 7. The stress receiving member 11h is formed on the back surface of the rib 7 (opposite side to the gusset plate) from near the upper end of the rib 7 toward the end of the fixing plate 3, so that the height of the stress receiving member 11h gradually decreases with increasing distance from the rib 7. Even in this case, the same effect as the fixing member 1d, etc. can be obtained.
（固定部材１ｋ）
図１１（ｂ）は、固定部材１ｋを示す斜視図である。固定部材１ｋは固定部材１ｊと略同様であるが、応力受け部材１１ｉが用いられる点で異なる。応力受け部材１１ｉは、リブ７の所定の範囲に接合される。応力受け部材１１ｉは、応力受け部材１１ｈと同様に、リブ７の背面（ガセットプレートとは逆方向）において、リブ７の上端部近傍から、固定板３の端部に向かって、リブ７から離れるにつれて徐々に高さが低くなるように形成される。また、固定板３の端部近傍においては、幅方向の両端部が円弧状に切り欠かれた形態である。この場合でも、固定部材１ｄ等と同様の効果を得ることができる。
(Fixing member 1k)
FIG. 11B is a perspective view showing the fixing member 1k. The fixing member 1k is substantially the same as the fixing member 1j, but differs in that a stress receiving member 11i is used. The stress receiving member 11i is joined to a predetermined area of the rib 7. The stress receiving member 11i is formed on the back surface of the rib 7 (opposite side to the gusset plate) in the same manner as the stress receiving member 11h, from the vicinity of the upper end of the rib 7 toward the end of the fixing plate 3, so that the height gradually decreases as it moves away from the rib 7. In addition, near the end of the fixing plate 3, both ends in the width direction are cut out in an arc shape. Even in this case, the same effect as the fixing member 1d can be obtained.
（固定部材１ｌ）
図１２は、固定部材１ｌを示す斜視図である。固定部材１ｌは固定部材１ａと略同様であるが、応力受け部材１１ｊが用いられる点で異なる。応力受け部材１１ｊは、リブ７の形成方向に互いに離間して、複数配置される。応力受け部材１１ｊは、一方の端部がリブ７の上端部近傍に接合され、他方の端部が、固定板３の端部近傍に固定され、リブ７から離れるにつれて徐々に高さが低くなるように形成される。なお、リブ７と固定板３との接合部においては、応力受け部材１１ｊはリブ７及び固定板３へ固定されず、空隙を有する。また、複数の応力受け部材１１ｊ同士が連結されていてもよい。この場合でも、固定部材１ａ等と同様の効果を得ることができる。
(Fixing member 1l)
FIG. 12 is a perspective view showing the fixing member 1l. The fixing member 1l is substantially the same as the fixing member 1a, but is different in that a stress receiving member 11j is used. A plurality of the stress receiving members 11j are arranged at intervals in the direction in which the rib 7 is formed. The stress receiving member 11j is formed so that one end is joined to the vicinity of the upper end of the rib 7 and the other end is fixed to the vicinity of the end of the fixing plate 3, and the height gradually decreases as it moves away from the rib 7. Note that at the joint between the rib 7 and the fixing plate 3, the stress receiving member 11j is not fixed to the rib 7 and the fixing plate 3, and has a gap. Also, a plurality of the stress receiving members 11j may be connected to each other. Even in this case, the same effect as the fixing member 1a and the like can be obtained.
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 embodiment of the present invention has been described above with reference to the attached drawings, the technical scope of the present invention is not limited to the above-mentioned embodiment. It is clear that a person skilled in the art can come up with various modified or revised examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally fall within the technical scope of the present invention.
例えば、上述した説明において、補強部材固定構造は、構造体の一方の側にガセットプレート付の固定部材１等が配置され、他方の側には、固定部材１０３が配置される例について説明したが、構造体の両側にガセットプレート付の固定部材を配置してもよい。すなわち、構造体をガセットプレート付の固定部材１等で挟み込んでもよい。この場合、構造体の両側の固定部材１等は、必ずしも同一の形状でなくてもよく、例えば、一方の側の固定部材と他方の側の固定部材とは、上述した各実施形態の組合わせであってもよい。 For example, in the above description, the reinforcing member fixing structure is described as an example in which a fixing member 1 with a gusset plate is arranged on one side of the structure and a fixing member 103 is arranged on the other side, but fixing members with gusset plates may be arranged on both sides of the structure. In other words, the structure may be sandwiched between fixing members 1 with gusset plates. In this case, the fixing members 1 on both sides of the structure do not necessarily have to have the same shape, and for example, the fixing member on one side and the fixing member on the other side may be a combination of the above-mentioned embodiments.
