Description

本発明は、固定具に関する。 The present invention relates to fasteners.

例えば側板の下部に下縁板が設けられているラック体を固定基材の載置部に固定するために、固定具が用いられている。このような固定具の一例が、特開２００２－３３５６１５号公報（特許文献１）に開示されている。 For example, a fixture is used to fix a rack body having a lower edge plate on the lower part of the side plate to the mounting portion of the fixed base material. An example of such a fixture is disclosed in Japanese Patent Laying-Open No. 2002-335615 (Patent Document 1).

特許文献１の固定具（ラック体振れ止め金具３０）は、ラック体（ラック体５）の側板（親桁６）の下縁板（縁板６ａ）に対して上方から当接する上側固定部材（上部金具３１）と、固定基材（溝形鋼１）の載置部（フランジ２）に対して下方から当接する下側固定部材（下部金具４１）と、それらに亘って設けられる締結部材（角根ボルト５０，ナット５２）とを備えている。上側固定部材は、ラック体の側板の下縁板と固定基材の載置部とに跨って配置されており、締結部材を締め付けたとき、当該上側固定部材の側縁部（押さえ板３３，３４）で、ラック体の側板の下縁板を上方から押さえる。 The fixture (rack body anti-vibration fitting 30) of Patent Document 1 is an upper fixing member ( An upper metal fitting 31), a lower fixing member (lower metal fitting 41) that abuts against the mounting portion (flange 2) of the fixing base material (channel steel 1) from below, and a fastening member ( Equipped with a square root bolt 50 and a nut 52). The upper fixing member is disposed across the lower edge plate of the side plate of the rack body and the mounting portion of the fixing base material, and when the fastening member is tightened, the side edge portion (holding plate 33, In 34), the lower edge plate of the side plate of the rack body is pressed from above.

しかし、特許文献１の固定具では、下縁板を押さえる部位である上側固定部材の側縁部と締結部材による締結位置とが離れているため、締結部材の締付力が作用しにくく、十分な強度を確保できない可能性があった。 However, in the fixing device of Patent Document 1, since the side edge of the upper fixing member, which is the part that presses the lower edge plate, and the fastening position of the fastening member are separated from each other, the fastening force of the fastening member does not easily act, and the fastening position is sufficient. There was a possibility that sufficient strength could not be secured.

特開２００２－３３５６１５号公報JP-A-2002-335615

ラック体を高い強度で固定基材に固定することができる固定具の実現が望まれる。 Realization of a fixture capable of fixing a rack body to a fixing base material with high strength is desired.

本発明に係る固定具は、
側板の下部に下縁板が設けられているラック体を固定基材の載置部に固定するための固定具であって、
前記載置部に対して上方から当接する上側固定部材と、
前記載置部に対して下方から当接する下側固定部材と、
前記上側固定部材と前記下側固定部材とに亘って設けられる締結部材と、を備え、
前記締結部材は、頭部を有する締結ボルトと、前記締結ボルトに螺合する締結ナットと、を含み、
前記締結部材の締め付けにより、前記下側固定部材と前記上側固定部材との間に前記載置部を挟み込み、かつ、前記頭部の直下の位置で前記下縁板の厚み分を吸収した状態で前記上側固定部材と前記頭部との間に前記下縁板を挟み込む。 The fixture according to the present invention is
A fixture for fixing a rack body having a lower edge plate on the lower part of the side plate to the mounting portion of the fixed base material,
an upper fixing member that abuts on the mounting portion from above;
a lower fixing member that abuts against the mounting portion from below;
a fastening member provided across the upper fixing member and the lower fixing member;
The fastening member includes a fastening bolt having a head and a fastening nut screwed onto the fastening bolt,
By tightening the fastening member, the mounting portion is sandwiched between the lower fixing member and the upper fixing member, and the thickness of the lower edge plate is absorbed at a position directly below the head. The lower edge plate is sandwiched between the upper fixing member and the head.

この構成によれば、締結部材を構成する締結ボルトの頭部の直下の位置で下縁板を挟み込むので、締結部材の締付力を下縁板に直接作用させることができる。その際、上側固定部材の上方に下縁板が載置されることによって生じ得る下縁板の厚み分相当の段差が解消されているので、締結部材を締め付けたときにその締付力を安定的に作用させることができる。これらのことから、上記構成の固定具を用いることで、ラック体を高い強度で固定基材に固定することができる。 According to this configuration, since the lower edge plate is sandwiched at the position directly below the head of the fastening bolt that constitutes the fastening member, the tightening force of the fastening member can be applied directly to the lower edge plate. At that time, since the step corresponding to the thickness of the lower edge plate that may be caused by placing the lower edge plate above the upper fixing member is eliminated, the tightening force is stabilized when the fastening member is tightened. can act effectively. For these reasons, the rack body can be fixed to the fixing base material with high strength by using the fixture having the above configuration.

以下、本発明の好適な態様について説明する。但し、以下に記載する好適な態様例によって、本発明の範囲が限定される訳ではない。 Preferred embodiments of the present invention are described below. However, the scope of the present invention is not limited by the preferred embodiments described below.

一態様として、
前記下縁板の厚みと同等の厚みを有し、前記上側固定部材と前記頭部との間に介在されて前記下縁板の端縁に側方から当接する介在部材をさらに備えることが好ましい。 As one aspect,
It is preferable to further include an intervening member that has a thickness equivalent to that of the lower edge plate, is interposed between the upper fixing member and the head portion, and contacts the edge of the lower edge plate from the side. .

この構成によれば、上側固定部材と締結ボルトの頭部との間に介在部材を介在させるだけで、その厚みによって下縁板の厚み分を適切に吸収することができる。また、下縁板の端縁に側方から介在部材を当接させることで、下縁板と介在部材とを隙間のない面一状に配置できるので、締結部材を締め付けたときにその締付力をより安定的に作用させることができる。 According to this configuration, the thickness of the lower edge plate can be appropriately absorbed by simply interposing the intervening member between the upper fixing member and the head of the fastening bolt. In addition, by bringing the intervening member into contact with the edge of the lower edge plate from the side, the lower edge plate and the intervening member can be arranged flush with each other without any gaps. Force can be applied more stably.

一態様として、
前記介在部材が、弾性変形可能なアーチ状プレートで構成されていることが好ましい。 As one aspect,
It is preferable that the intervening member is composed of an elastically deformable arch-shaped plate.

この構成によれば、締結部材の締付前に、上側固定部材と締結ボルトの頭部との間に、介在部材を構成するアーチ状プレートの高さに応じた隙間（アーチ状プレート及び下縁板の厚みよりも大きい隙間）を形成することができる。よって、上側固定部材と締結ボルトの頭部との間にラック体の側板の下縁板を差し込む操作を容易に行うことができる。アーチ状プレートは弾性変形可能であるので、締結部材の締め付けに伴い、全体形状を容易に平坦化することができる。よって、下縁板の厚み分を容易かつ適切に吸収することができる。 According to this configuration, before the fastening member is tightened, a gap corresponding to the height of the arch-shaped plate constituting the intervening member (the arch-shaped plate and the lower edge A gap larger than the thickness of the plate) can be formed. Therefore, the operation of inserting the lower edge plate of the side plate of the rack body between the upper fixing member and the head of the fastening bolt can be easily performed. Since the arch-shaped plate is elastically deformable, the overall shape can be easily flattened as the fastening member is tightened. Therefore, the thickness of the lower edge plate can be easily and appropriately absorbed.

一態様として、
前記介在部材が、前記上側固定部材に対して回り止めされた状態で前記締結部材に挿通保持されていることが好ましい。 As one aspect,
It is preferable that the intervening member is inserted through and held by the fastening member while being prevented from rotating with respect to the upper fixing member.

この構成によれば、固定具を例えば締結部材の緩締状態で搬送する場合等においても、上側固定部材に対する介在部材の姿勢を適正姿勢に維持することができる。これにより、現場で固定基材にラック体を固定する際に、ラック体の側板の下縁板の端縁に側方から介在部材を容易に当接させることができる。よって、施工性を向上させることができる。 According to this configuration, even when the fixture is transported with the fastening member loosely tightened, for example, the posture of the intervening member with respect to the upper fixing member can be maintained at a proper posture. As a result, when the rack body is fixed to the fixed base material on site, the intervening member can be easily brought into contact with the edge of the lower edge plate of the side plate of the rack body from the side. Therefore, workability can be improved.

一態様として、
前記上側固定部材と前記下側固定部材とが、相対回転不能かつ相対近接移動可能な状態で連結されていることが好ましい。 As one aspect,
It is preferable that the upper fixing member and the lower fixing member are connected so as to be non-rotatable relative to each other and movable relative to each other.

この構成によれば、上側固定部材と下側固定部材とが相対回転不能なので、一定の姿勢を維持したままで固定基材とラック体とを容易に固定することができる。また、上側固定部材と下側固定部材とが相対近接移動可能なので、下側固定部材と上側固定部材との間に載置部を適切に挟み込める。 According to this configuration, since the upper fixing member and the lower fixing member cannot rotate relative to each other, it is possible to easily fix the fixing base material and the rack body while maintaining a fixed posture. In addition, since the upper fixing member and the lower fixing member can move toward each other, the mounting portion can be appropriately sandwiched between the lower fixing member and the upper fixing member.

一態様として、
前記上側固定部材と前記下側固定部材とが別体で構成され、
前記上側固定部材と前記下側固定部材とが、前記締結部材による締結位置を挟んだ両側に設けられた一対の連結予定部位のいずれかにおいて択一的に連結されていることが好ましい。 As one aspect,
The upper fixing member and the lower fixing member are configured separately,
It is preferable that the upper fixing member and the lower fixing member are alternatively connected at one of a pair of planned connection portions provided on both sides of the fastening position of the fastening member.

この構成によれば、上側固定部材と下側固定部材との連結位置を一対の連結予定部位のいずれかとすることで、固定基材及びラック体に対する取り付けの向きを切り替えることができる。よって、それぞれ単一種の上側固定部材と下側固定部材とを用いつつ、向き違いの固定具を例えば施工現場で簡単に作り分けることができる。 According to this configuration, by setting the connection position of the upper fixing member and the lower fixing member to either of the pair of planned connection portions, it is possible to switch the attachment orientation with respect to the fixing base material and the rack body. Therefore, while using a single type of upper fixing member and lower fixing member, it is possible to easily produce fixtures with different orientations, for example, at a construction site.

一態様として、
前記下側固定部材に、前記締結ナットの回転を規制する回転規制部が設けられていることが好ましい。 As one aspect,
It is preferable that the lower fixing member is provided with a rotation restricting portion that restricts rotation of the fastening nut.

この構成によれば、締結ナットが回り止めされているので、締結ボルトを操作するだけで簡単に固定基材とラック体とを固定することができる。 According to this configuration, since the fastening nut is prevented from rotating, the fastening base and the rack body can be easily fixed simply by operating the fastening bolt.

一態様として、
前記下側固定部材は、前記載置部に当接する下側本体部と、前記下側本体部よりも下方において折り返された下方折返部と、を有し、
前記下方折返部に、前記回転規制部として、前記締結ナットにおける対向する２つの側面に係止可能な一対の係止片が設けられていることが好ましい。 As one aspect,
The lower fixing member has a lower main body portion that abuts on the mounting portion and a lower folded portion that is folded back below the lower main body portion,
It is preferable that the lower folded portion is provided with a pair of locking pieces that can be locked to two opposing side surfaces of the fastening nut as the rotation restricting portion.

この構成によれば、一対の係止片が下側本体部よりも下方にある下方折返部に設けられているので、締結ナットとして例えば鍔付ナットを用いる場合でも、締結ナットの回転を適切に規制することができる。 According to this configuration, since the pair of locking pieces are provided on the lower folded portion below the lower body portion, even when a flanged nut, for example, is used as the fastening nut, the rotation of the fastening nut can be properly controlled. can be regulated.

一態様として、
前記上側固定部材と前記下側固定部材とが一体的に構成されていることが好ましい。 As one aspect,
It is preferable that the upper fixing member and the lower fixing member are configured integrally.

この構成によれば、部品材料や製造のための金型が少なく済み、低コストに作製することができる。また、上側固定部材と下側固定部材とを組み立てる必要がなくそのまま使用できるので、施工時間を短く抑えることができる。 According to this configuration, the parts materials and molds for manufacturing can be reduced, and the manufacturing can be performed at low cost. In addition, since the upper fixing member and the lower fixing member can be used as they are without the need to assemble them, the construction time can be shortened.

一態様として、
前記上側固定部材と前記下側固定部材とが別体で構成されていることが好ましい。 As one aspect,
It is preferable that the upper fixing member and the lower fixing member are configured separately.

この構成によれば、上側固定部材及び下側固定部材のそれぞれを個別に作製することができるので、全体として加工が容易である。 According to this configuration, the upper fixing member and the lower fixing member can be manufactured separately, so that the processing as a whole is easy.

一態様として、
前記締結部材の締め付けにより、前記上側固定部材と前記下側固定部材とが平行状態を維持しながら近接移動することが好ましい。 As one aspect,
It is preferable that the tightening of the fastening member causes the upper fixing member and the lower fixing member to move toward each other while maintaining a parallel state.

この構成によれば、上側固定部材と下側固定部材とで、これらの間に固定基材の載置部を安定的に挟み込むことができる。例えば固定基材の載置部の厚みが種々異なる場合であっても、上側固定部材と下側固定部材とで載置部を略一定の力で挟み込むことができる。よって、固定基材に対してラック体を安定的に固定することができる。 According to this configuration, the mounting portion of the fixing base material can be stably sandwiched between the upper fixing member and the lower fixing member. For example, even if the thickness of the mounting portion of the fixed base material varies, the mounting portion can be held between the upper fixing member and the lower fixing member with a substantially constant force. Therefore, the rack body can be stably fixed to the fixed base material.

本発明に係るもう１つの固定具は、
側板の下部に下縁板が設けられているラック体を固定基材の載置部に固定するための固定具であって、
前記載置部に対して上方から当接する介在部材と、
前記載置部に対して下方から当接する下側固定部材と、
前記介在部材と前記下側固定部材とに亘って設けられる締結部材と、を備え、
前記締結部材は、頭部を有する締結ボルトと、前記締結ボルトに螺合する締結ナットと、を含み、
前記介在部材は、前記下縁板の厚みと同等の厚みを有し、前記締結ボルトの軸部が貫通する状態で前記下縁板の側方に配置され、
前記締結部材の締め付けにより、前記頭部の直下の位置で前記介在部材と前記下縁板とに亘って前記載置部と前記頭部との間に前記下縁板を挟み込む。 Another fixture according to the invention comprises:
A fixture for fixing a rack body having a lower edge plate on the lower part of the side plate to the mounting portion of the fixed base material,
an intervening member that abuts against the mounting portion from above;
a lower fixing member that abuts against the mounting portion from below;
a fastening member provided across the intervening member and the lower fixing member;
The fastening member includes a fastening bolt having a head and a fastening nut screwed onto the fastening bolt,
The intervening member has a thickness equivalent to the thickness of the lower edge plate, and is arranged to the side of the lower edge plate in a state in which the shaft portion of the fastening bolt penetrates,
By tightening the fastening member, the lower edge plate is sandwiched between the mounting portion and the head over the intermediate member and the lower edge plate at a position directly below the head.

この構成によれば、締結部材を構成する締結ボルトの頭部の直下の位置で下縁板を挟み込むので、締結部材の締付力を下縁板に直接作用させることができる。その際、固定基材の載置部に下縁板が載置されることによって生じ得る下縁板の厚み分相当の段差が介在部材によって解消されているので、締結部材を締め付けたときにその締付力を安定的に作用させることができる。これらのことから、上記構成の固定具を用いることで、ラック体を高い強度で固定基材に固定することができる。 According to this configuration, since the lower edge plate is sandwiched at the position directly below the head of the fastening bolt that constitutes the fastening member, the tightening force of the fastening member can be applied directly to the lower edge plate. At this time, since the intervening member eliminates a step corresponding to the thickness of the lower edge plate that may be caused by placing the lower edge plate on the mounting portion of the fixed base material, when the fastening member is tightened, the height difference is eliminated. The tightening force can be stably applied. For these reasons, the rack body can be fixed to the fixing base material with high strength by using the fixture having the above configuration.

The width of the cutout portion 38 is set to be equal to or slightly wider than the interval between two opposed side surfaces of the hexagonal portion 45A of the fastening nut 45 that constitutes the fastening member 4 .

下方折返部３７における切欠部３８の両側に位置する部分は、一対の係止片３７Ａとして、締結ナット４５の六角部４５Ａにおける対向する２つの側面に係止可能となっている。 Portions of the lower folded portion 37 located on both sides of the cutout portion 38 can be locked to two opposing side surfaces of the hexagonal portion 45A of the fastening nut 45 as a pair of locking pieces 37A.

締結部材４は、上側固定部材２と下側固定部材３とに亘って設けられる。締結部材４は、締結ボルト４１と、締結ボルト４１に螺合する締結ナット４５とを有する。本実施形態では、締結ボルト４１として、いわゆるフランジボルトを用いている。締結ボルト４１は、六角部４２Ａと鍔部４２Ｂとが一体化された頭部４２と、外面にネジ山が切られた軸部４３とを有する。鍔部４２Ｂは、六角部４２Ａよりもひと回り大きい円形状に形成されており、六角部４２Ａにおける軸部４３側の端部で六角部４２Ａと一体化されている。 The fastening member 4 is provided across the upper fixing member 2 and the lower fixing member 3 . The fastening member 4 has a fastening bolt 41 and a fastening nut 45 screwed onto the fastening bolt 41 . In this embodiment, so-called flange bolts are used as the fastening bolts 41 . The fastening bolt 41 has a head portion 42 in which a hexagonal portion 42A and a flange portion 42B are integrated, and a shaft portion 43 having a threaded outer surface. The collar portion 42B is formed in a circular shape slightly larger than the hexagonal portion 42A, and is integrated with the hexagonal portion 42A at the end portion of the hexagonal portion 42A on the shaft portion 43 side.

また、本実施形態では、締結ナット４５として、いわゆるフランジナットを用いている。締結ナット４５は、六角部４５Ａと鍔部４５Ｂとが一体化されて構成されている。六角部４５Ａは、内面にネジ山が切られた締結孔を有する。鍔部４５Ｂは、六角部４５Ａよりもひと回り大きい円形状に形成されており、六角部４５Ａにおける一方側の端部で六角部４５Ａと一体化されている。 Moreover, in this embodiment, a so-called flange nut is used as the fastening nut 45 . The fastening nut 45 is configured by integrating a hexagonal portion 45A and a collar portion 45B. The hexagonal portion 45A has a fastening hole threaded on the inner surface. The collar portion 45B is formed in a circular shape slightly larger than the hexagonal portion 45A, and is integrated with the hexagonal portion 45A at one end of the hexagonal portion 45A.

締結部材４は、締結ボルト４１の軸部４３が上側固定部材２のボルト挿通孔２２と下側固定部材３のボルト挿通孔３２とに挿通された状態で締結ナット４５が締結されることで、締結ボルト４１の頭部４２と締結ナット４５との間に上側固定部材２と下側固定部材３とを挟み込む。 The fastening member 4 is fastened with the fastening nut 45 in a state in which the shaft portion 43 of the fastening bolt 41 is inserted through the bolt insertion hole 22 of the upper fixing member 2 and the bolt insertion hole 32 of the lower fixing member 3. The upper fixing member 2 and the lower fixing member 3 are sandwiched between the head 42 of the fastening bolt 41 and the fastening nut 45 .

このとき、上側固定部材２の連結孔２３に下側固定部材３の連結片３５も係止しているので、上側固定部材２と下側固定部材３とは、相対回転不能な状態で連結されている。また、上側固定部材２と下側固定部材３とは、締結部材４が締結されていない状態（緩締状態）では、連結孔２３と連結片３５との係止箇所を支点として相対近接移動可能（具体的には、揺動可能）な状態で連結されている。 At this time, since the connecting piece 35 of the lower fixing member 3 is also engaged with the connecting hole 23 of the upper fixing member 2, the upper fixing member 2 and the lower fixing member 3 are connected in a non-rotatable state. ing. In addition, the upper fixing member 2 and the lower fixing member 3 can move toward each other relative to each other using the engagement point between the connecting hole 23 and the connecting piece 35 as a fulcrum when the fastening member 4 is not tightened (loosely tightened state). (Specifically, they are connected in a swingable state).

本実施形態の固定具１は、上側固定部材２の上側に配置されて上側固定部材２と締結ボルト４１の頭部４２との間に介在される介在部材５をさらに備えている。このような介在部材５として、本実施形態では、略矩形状に形成されているとともに上方に向かって凸となるように緩やかに湾曲するアーチ状プレート５１を用いている。 The fixture 1 of this embodiment further includes an intervening member 5 that is arranged above the upper fixing member 2 and interposed between the upper fixing member 2 and the head portion 42 of the fastening bolt 41 . As such an intervening member 5, in the present embodiment, an arch-shaped plate 51 which is formed in a substantially rectangular shape and which is gently curved so as to protrude upward is used.

アーチ状プレート５１は、切欠孔５２を有する。切欠孔５２は、アーチ状プレート５１の頂部において、上下に貫通する円形状の貫通孔が一辺側に開口するように形成されている。この切欠孔５２には、締結部材４を構成する締結ボルト４１の軸部４３が挿通される。また、アーチ状プレート５１の上面に、本実施形態では締結ボルト４１の頭部４２が直接当接する。 The arched plate 51 has a cutout hole 52 . The notch hole 52 is formed in the top part of the arch-shaped plate 51 so that a circular through hole penetrating vertically is opened on one side. The shaft portion 43 of the fastening bolt 41 constituting the fastening member 4 is inserted through the cutout hole 52 . Also, in this embodiment, the head portion 42 of the fastening bolt 41 directly abuts on the upper surface of the arch-shaped plate 51 .

アーチ状プレート５１は、切欠孔５２が開口している側の辺部の対辺が、上側固定部材２の第一上方延出部２４に沿うように配置される（図４及び図６も参照）。また、アーチ状プレート５１は、上側固定部材２における第二上方延出部２６側の部分の上面に載置されるラック体８の側板８１の下縁板８６の端縁８６ｅに対して側方から当接する。アーチ状プレート５１は、少なくとも、裾野部分となるその両端部において下縁板８６の端縁８６ｅに当接する（図５及び図６の上段を参照）。 The arch-shaped plate 51 is arranged such that the opposite side of the side where the cutout hole 52 is open is along the first upwardly extending portion 24 of the upper fixing member 2 (see also FIGS. 4 and 6). . Also, the arch-shaped plate 51 is lateral to the edge 86e of the lower edge plate 86 of the side plate 81 of the rack body 8 placed on the upper surface of the portion of the upper fixing member 2 on the side of the second upwardly extending portion 26 . abut from The arch-shaped plate 51 abuts on the edge 86e of the lower edge plate 86 at least at both ends thereof, which are skirt portions (see the upper part of FIGS. 5 and 6).

アーチ状プレート５１の厚みは、ラック体８の側板８１の下縁板８６の厚みと同等に設定されている。ここで、厚みが「同等」とは、同一であることはもちろんのこと、同一とみなせる程度に近似していることを意味する。アーチ状プレート５１の厚みは、例えばラック体８の側板８１の下縁板８６の厚みを基準としてその±１５％、好ましくは±１０％、さらに好ましくは±５％に設定される。 The thickness of the arch-shaped plate 51 is set equal to the thickness of the lower edge plate 86 of the side plate 81 of the rack body 8 . Here, "equal" in thickness means that the thickness is not only the same but also approximate enough to be regarded as the same. The thickness of the arch plate 51 is set to ±15%, preferably ±10%, more preferably ±5% of the thickness of the lower edge plate 86 of the side plate 81 of the rack body 8, for example.

また、アーチ状プレート５１は弾性変形可能であり、締結部材４の締結によって締付力が作用すると、次第に平坦化し、最終的に上側固定部材２（具体的には、上側本体部２１）の上面に沿う平板状に変形する（図６の下段を参照）。 Also, the arch-shaped plate 51 is elastically deformable, and when a tightening force acts upon the fastening of the fastening member 4, it gradually flattens and finally flattens the upper surface of the upper fixing member 2 (specifically, the upper body portion 21). (see the lower part of FIG. 6).

このような固定具１を用いることで、締結部材４の締め付けにより、下側固定部材３と上側固定部材２との間に固定基材９の載置部９３を挟み込み（図５を参照）、かつ、締結ボルト４１の頭部４２の直下の位置でラック体８の側板８１の下縁板８６の厚み分をアーチ状プレート５１で吸収した状態で、上側固定部材２と頭部４２との間に下縁板８６を挟み込む（図４及び図６の下段を参照）。 By using such a fixture 1, by tightening the fastening member 4, the mounting portion 93 of the fixing base material 9 is sandwiched between the lower fixing member 3 and the upper fixing member 2 (see FIG. 5), In addition, in a state where the thickness of the lower edge plate 86 of the side plate 81 of the rack body 8 is absorbed by the arch-shaped plate 51 at the position directly below the head 42 of the fastening bolt 41, the upper fixing member 2 and the head 42 are fixed. The lower edge plate 86 is sandwiched between (see the lower part of FIGS. 4 and 6).

従来から多用されてきた固定具では、上側固定部材２に相当する部材が載置部９３と下縁板８６とに跨るようにこれらの上方に配置され、締結部材４の締付力は上側固定部材２に相当する部材を介して載置部９３及び下縁板８６に作用するものであった。 In the fixture that has been widely used in the past, a member corresponding to the upper fixing member 2 is arranged above the mounting portion 93 and the lower edge plate 86 so as to straddle them, and the tightening force of the fastening member 4 is fixed to the upper side. It acts on the mounting portion 93 and the lower edge plate 86 via a member corresponding to the member 2 .

これに対して、本実施形態では、上側固定部材２が載置部９３と下縁板８６との間に挿入され、上側固定部材２の上面側で締結ボルト４１の頭部４２で下縁板８６を直接押さえている。このとき、ラック体８の側板８１の下縁板８６の厚みと同等の厚みを有するアーチ状プレート５１を介在させることで、実質的に段差がない状態となっている。これにより、締結部材４の締付力を下縁板８６に直接かつ安定的に作用させることができ、ラック体８を高い強度で固定基材９に固定することができる。 In contrast, in this embodiment, the upper fixing member 2 is inserted between the mounting portion 93 and the lower edge plate 86 , and the lower edge plate is held by the head 42 of the fastening bolt 41 on the upper surface side of the upper fixing member 2 . 86 is pressed directly. At this time, by interposing the arch-shaped plate 51 having the same thickness as the lower edge plate 86 of the side plate 81 of the rack body 8 , there is substantially no step. As a result, the tightening force of the fastening member 4 can be applied directly and stably to the lower edge plate 86, and the rack body 8 can be fixed to the fixed base material 9 with high strength.

また、固定強度が向上することにより、例えばラック体８が一対の側板８１の上部開口を覆う天板を備え、その天板上を歩路として利用する場合に、安定性ひいては安全性を高めることができる。 In addition, by improving the fixing strength, for example, when the rack body 8 is provided with a top plate covering the upper opening of the pair of side plates 81 and the top plate is used as a walkway, stability and safety can be improved. can be done.

なお、ラック体８を固定基材９に固定するには、載置部９３と側板８１の下縁板８６とが交差する箇所の付近の、載置部９３とは重複しない位置において、まず、締結部材４が緩締状態となっている固定具１を下縁板８６に差し込む。このとき、締結部材４の緩締状態では介在部材５としてのアーチ状プレート５１は上方に向かって凸となるように湾曲したままの状態なので、上側固定部材２と締結ボルト４１の頭部４２との間の隙間が比較的大きく、下縁板８６に差し込みやすい。また、下縁板８６の端縁８６ｅがアーチ状プレート５１の側面に当接するまで差し込むだけで、下縁板８６に対して固定具１を適切に位置決めすることができる。 In addition, in order to fix the rack body 8 to the fixed base material 9, first, at a position near the intersection of the mounting portion 93 and the lower edge plate 86 of the side plate 81, which does not overlap with the mounting portion 93, The fixture 1 with the fastening member 4 loosely tightened is inserted into the lower edge plate 86 . At this time, when the fastening member 4 is loosely tightened, the arch-shaped plate 51 as the intervening member 5 is in a state of being curved so as to protrude upward. The gap between is relatively large, and it is easy to insert into the lower edge plate 86. - 特許庁Further, the fixture 1 can be properly positioned with respect to the lower edge plate 86 simply by inserting it until the edge 86 e of the lower edge plate 86 comes into contact with the side surface of the arch-shaped plate 51 .

その後、側板８１をやや持ち上げながら固定具１を載置部９３側にスライドさせて、載置部９３に取り付ける。このとき、下縁板８６が上面側に載置されている上側固定部材２が載置部９３の上面に載置され、かつ、下側固定部材３が載置部９３の下面に当接するように、固定具１がスライド移動される。下側固定部材３は上側固定部材２に対して連結孔２３と連結片３５との係止箇所を支点として揺動可能なので、間口が広がることによって載置部９３に容易に取り付けることができる。また、下側固定部材３の傾斜面部３６が、下側固定部材３を載置部９３の下方側に向かわせるためのガイドとして機能するので、この点からも固定具１を載置部９３に容易に取り付けることができる。さらに、第一補強部２５及び第二補強部２７の外面が載置部９３の端面に当接するまでスライドさせるだけで、載置部９３に対しても固定具１を適切に位置決めすることができる。 After that, while lifting the side plate 81 slightly, the fixture 1 is slid toward the mounting portion 93 and attached to the mounting portion 93 . At this time, the upper fixing member 2 on which the lower edge plate 86 is placed on the upper surface side is placed on the upper surface of the placing portion 93 , and the lower fixing member 3 is placed in contact with the lower surface of the placing portion 93 . Then, the fixture 1 is slid. Since the lower fixing member 3 can swing with respect to the upper fixing member 2 around the engagement point between the connecting hole 23 and the connecting piece 35 as a fulcrum, it can be easily attached to the mounting portion 93 by widening the frontage. In addition, since the inclined surface portion 36 of the lower fixing member 3 functions as a guide for directing the lower fixing member 3 toward the lower side of the mounting portion 93, the fixture 1 is attached to the mounting portion 93 from this point as well. Easy to install. Furthermore, the fixture 1 can be properly positioned with respect to the mounting portion 93 by simply sliding the outer surfaces of the first reinforcing portion 25 and the second reinforcing portion 27 until they abut against the end surface of the mounting portion 93 . .

最後に、締結ボルト４１を締付操作して、締結部材４を締結する。このとき、下側固定部材３に設けられた一対の係止片３７Ａが締結ナット４５に係止することで、締結ナット４５が回転するのを規制することができ、締結ボルト４１の締付操作を容易に行うことができる。一対の係止片３７Ａは、下側本体部３１よりも下方に配置されているので、本実施形態のように締結ナット４５としてフランジナットを用いる場合でも、鍔部４５Ｂを避けて締結ナット４５の回転規制を適切に行うことができる。本実施形態では、これら一対の係止片３７Ａにより、「回転規制部」が構成されている。 Finally, the fastening member 4 is fastened by tightening the fastening bolt 41 . At this time, the pair of locking pieces 37A provided on the lower fixing member 3 are locked to the fastening nut 45 so that the rotation of the fastening nut 45 can be restricted. can be easily done. Since the pair of locking pieces 37A are arranged below the lower main body portion 31, even when a flange nut is used as the fastening nut 45 as in the present embodiment, the fastening nut 45 can be secured while avoiding the flange portion 45B. Rotation regulation can be performed appropriately. In this embodiment, the pair of locking pieces 37A constitute a "rotation restricting portion".

ところで、ラック体８は一対の側板８１を備えており、これら一対の側板８１はそれぞれの上縁板８４及び下縁板８６が互いに向かい合う姿勢で対向配置される。このため、固定具１としては、上側固定部材２に対する下側固定部材３の連結向きが互いに逆向きとなる２種が必要となる。この点、本実施形態の固定具１においては、上側本体部２１に、締結部材４による締結位置となるボルト挿通孔２２を挟んだ両側に、２つの連結孔２３（第一連結孔２３Ａ，第二連結孔２３Ｂ）が分かれて形成されている。 By the way, the rack body 8 is provided with a pair of side plates 81, and these pair of side plates 81 are arranged so that the upper edge plate 84 and the lower edge plate 86 face each other. For this reason, two types of fixtures 1 are required in which the connection directions of the lower fixing member 3 with respect to the upper fixing member 2 are opposite to each other. In this regard, in the fixture 1 of the present embodiment, two connecting holes 23 (first connecting hole 23A, second Two connecting holes 23B) are formed separately.

これら２つの連結孔２３（第一連結孔２３Ａ，第二連結孔２３Ｂ）のいずれかに、上側固定部材２に設けられた連結片３５を選択的に係止させることで、共通の構成部品を用いつつ、向き違いの２種の固定具１を作り出すことができる。本実施形態では、連結孔２３が「連結予定部位」に相当する。施工現場での簡単な付け替え作業によって向きを変更することができるので、全体での必要個数さえ把握しておけば良く、在庫管理が省力化されるという利点もある。 By selectively locking a connecting piece 35 provided on the upper fixing member 2 to one of these two connecting holes 23 (first connecting hole 23A, second connecting hole 23B), a common component can be It is possible to create two types of fixtures 1 with different orientations while using them. In this embodiment, the connecting hole 23 corresponds to the "planned connecting part". Since the direction can be changed by a simple replacement work at the construction site, it is sufficient to know the total number of required pieces, which also has the advantage of saving labor in inventory management.
