Description

接合構造Junction structure

　本発明は、被固定部材を固定部材に固定する接合構造に関し、詳しくは、固定部材に対して被固定部材の傾き角度及び傾き方向を調整可能な接合構造に関するものである。 The present invention relates to a joining structure for fixing a member to be fixed to a fixing member, and more particularly to a joining structure capable of adjusting the inclination angle and the inclination direction of the member to be fixed with respect to the fixing member.

　太陽光発電パネル設置用架台、大型のアンテナ装置、建築物の基礎梁等の比較的大型の被固定部材を地上に設置する場合には、地盤に支持杭等の固定部材を立設して、その上端部に被固定部材が取付けられることが多い。 When installing a relatively large fixed member such as a photovoltaic power generation panel installation base, a large antenna device, a foundation beam of a building on the ground, a fixing member such as a support pile is erected on the ground, A fixed member is often attached to the upper end portion.

　急傾斜地、硬い地盤、地中障害物が多いなどの厳しい施工環境において支持杭の打設を行う場合には、杭の倒れ、ねじれ、高さの誤差（総称して施工誤差）が発生し易い。従って、支持杭等の固定部材に上部構造等の被固定部材を固定する際には、前記の施工誤差を吸収できる調整機能付きの接合構造が必要とされる。この種の調整機能付きの接合構造として、例えば、特許文献１及び２に開示された構造がある。 When placing support piles in harsh construction environments such as steep slopes, hard ground, and many obstacles in the ground, pile errors, twists, and height errors (collectively construction errors) are likely to occur. . Therefore, when a fixed member such as an upper structure is fixed to a fixing member such as a support pile, a joining structure with an adjustment function that can absorb the construction error is required. As this type of joint structure with an adjustment function, for example, there are structures disclosed in Patent Documents 1 and 2.

　特許文献１に開示されている取付物支持ユニット１１（接合構造）は、球座部２３を具備する受け座部２８Ｕと、球座部２３の湾曲受け面２３ａに凹曲面３８を面接触させ取付物が固定される取付台座部材３０と、取付台座部材３０を球座部２３に締め付け固定する固定用ボルト５０とを有している。そして、取付台座部材３０の凹曲面の中央部に開口されたボルト挿通孔３５内に、球座部２３の湾曲受け面に沿う取付台座部材３０のスライド移動を可能にするクリアランスが確保されている。取付物支持ユニット１１の取付台座部材３０は、受け座部２８Ｕの球座部２３に固定されていない状態において、球座部２３の湾曲受け面２３ａに沿ってスライド移動可能であるため、受け座部２８Ｕに対する向きを簡単に調整できる。また、取付台座部材３０が受け座部２８Ｕにボルト固定された後、再度、取付台座部材３０の向きを調整したい場合には、固定用ボルト５０を緩めることで簡単に再調整ができる。 The attachment support unit 11 (joint structure) disclosed in Patent Document 1 is mounted by bringing a concave curved surface 38 into surface contact with a receiving seat portion 28U having a ball seat portion 23 and a curved receiving surface 23a of the ball seat portion 23. A mounting base member 30 to which an object is fixed and a fixing bolt 50 for fastening and fixing the mounting base member 30 to the ball seat portion 23 are provided. And the clearance which enables the slide movement of the mounting base member 30 along the curved receiving surface of the ball seat part 23 is ensured in the bolt insertion hole 35 opened in the center part of the concave curved surface of the mounting base member 30. . The mounting base member 30 of the attachment support unit 11 is slidable along the curved receiving surface 23a of the ball seat 23 in a state where it is not fixed to the ball seat 23 of the receiving seat 28U. The direction with respect to the portion 28U can be easily adjusted. In addition, after the mounting base member 30 is bolted to the receiving seat portion 28U, when it is desired to adjust the direction of the mounting base member 30 again, the fixing bolt 50 can be loosened and the readjustment can be easily performed.

　特許文献２に開示されている接合構造７は、基礎梁５と鋼管杭３とを接続する構造であり、杭頭キャップ１９に支承される凸面１１ｂを有した球座頭ボルト１１と、球座頭ボルト１１の一方の端部である頭部１１ｃを杭頭キャップ１９に固定する位置調整部２１（固定手段）と、球座頭ボルト１１の他方の端部と基礎梁５とを連結する基礎梁固定プレート９とを備えている。位置調整部２１は、球座頭ボルト１１の他方の端部が挿通する挿通孔Ｈａを有し、挿通孔Ｈａは、球座頭ボルト１１が揺動自在の孔径を有している。そして、位置調整部２１が球座頭ボルト１１の径方向への張出し部に当接することによって、球座頭ボルト１１が位置調整部２１の挿通孔Ｈａから抜け出さないように係止される。従って、杭頭キャップ１９に支承される凸面１１ｂを支点として、球座頭ボルト１１を挿通孔Ｈａ内で傾けながら調整することで、基礎梁５の設置状態の傾きの誤差を簡単に調整でき、寸法精度よく基礎梁５を鋼管杭３に容易に接続することができる。 The joint structure 7 disclosed in Patent Document 2 is a structure for connecting the foundation beam 5 and the steel pipe pile 3, and a ball seat head bolt 11 having a convex surface 11 b supported by a pile head cap 19 and a ball seat head bolt. A base beam fixing plate for connecting the other end of the ball head bolt 11 and the base beam 5 to a position adjusting portion 21 (fixing means) for fixing the head 11c, which is one end of the head 11, to the pile head cap 19. 9 and. The position adjusting unit 21 has an insertion hole Ha through which the other end of the ball head bolt 11 is inserted, and the insertion hole Ha has a hole diameter that allows the ball head bolt 11 to swing. Then, when the position adjusting portion 21 comes into contact with the radially extending portion of the ball head bolt 11, the ball head bolt 11 is locked so as not to come out of the insertion hole Ha of the position adjusting portion 21. Therefore, by adjusting the ball head bolt 11 while tilting the ball head bolt 11 in the insertion hole Ha with the convex surface 11b supported by the pile head cap 19 as a fulcrum, the tilt error of the installed state of the foundation beam 5 can be easily adjusted. The foundation beam 5 can be easily connected to the steel pipe pile 3 with high accuracy.

　ここで、特許文献１に開示されている取付物支持ユニット１１は、取付台座部材３０の凹曲面の中央部に開口されたボルト挿通孔３５に固定用ボルト５０が挿通されている。従って、取付台座部材３０に取付物が固定された状態では、固定用ボルト５０の頭部が取付物に覆われてしまう場合があり、固定用ボルト５０を緩めての再調整が不可能になる虞がある。 Here, in the attachment support unit 11 disclosed in Patent Document 1, the fixing bolt 50 is inserted into the bolt insertion hole 35 opened at the center of the concave surface of the mounting base member 30. Therefore, in a state where the attachment is fixed to the attachment base member 30, the head of the fixing bolt 50 may be covered with the attachment, and the readjustment after loosening the fixing bolt 50 becomes impossible. There is a fear.

　また、特許文献２に開示されている接合構造７は、球座頭ボルト１１が頭部１１ｃに形成された凸面１１ｂを支点として揺動自在となっている。すなわち、球座頭ボルト１１は、一点支持の点接触の状態となっている。また、球座頭ボルト１１の頭部１１ｃの張り出した側面が、位置調整部２１の挿通孔Ｈａの内周面に当接することによって、球座頭ボルト１１が位置調整部２１の挿通孔Ｈａから抜け出さないように係止される。このため、傾いた状態の球座頭ボルト１１を保持する際には、球座頭ボルト１１の頭部１１ｃの側面と位置調整部２１の挿通孔Ｈａの内周面との接触面積が減少し、二点接触の状態で保持されることとなる。 Further, in the joint structure 7 disclosed in Patent Document 2, the ball head bolt 11 is swingable with a convex surface 11b formed on the head 11c as a fulcrum. That is, the ball head bolt 11 is in a point contact state with one point support. Further, the protruding side surface of the head 11 c of the ball head bolt 11 comes into contact with the inner peripheral surface of the insertion hole Ha of the position adjustment unit 21, so that the ball head bolt 11 does not come out of the insertion hole Ha of the position adjustment unit 21. It is locked as follows. For this reason, when the tilted ball head bolt 11 is held, the contact area between the side surface of the head 11c of the ball head bolt 11 and the inner peripheral surface of the insertion hole Ha of the position adjusting portion 21 is reduced. It will be held in a point contact state.

　すなわち、傾いた状態の球座頭ボルト１１は、頭部１１ｃが凸部の一点と張出し部の二点の合計三点で保持された状態となっている。この状態では、球座頭ボルト１１の傾きを固定する方向に対しては保持力が強いが、傾き方向に直交する方向に対しては保持力が最も弱く、傾いた状態の球座頭ボルト１１の保持力の強さに方向性が生じるという問題がある。また、点接触の保持では、接触点に荷重が集中するため、長期的に接触点が凹み易く（クリープ変形）、これにより、接触点の接触圧が低下して、球座頭ボルト１１の保持力が長期的に損なわれる虞がある。 That is, the ball head bolt 11 in the tilted state is in a state where the head 11c is held at a total of three points, one point of the convex portion and two points of the protruding portion. In this state, the holding force is strong in the direction in which the inclination of the ball head bolt 11 is fixed, but the holding force is weakest in the direction perpendicular to the inclination direction, and the holding of the ball head bolt 11 in the inclined state is held. There is a problem that directionality occurs in the strength of power. Further, in the point contact holding, since the load concentrates on the contact point, the contact point is likely to dent for a long term (creep deformation), thereby reducing the contact pressure at the contact point and holding force of the ball head bolt 11. May be damaged in the long term.

　本発明は、上記実情に鑑みてなされたものであり、固定部材に対して被固定部材の傾き角度及び傾き方向を調整可能であるとともに、傾き角度及び傾き方向によらず被固定部材を安定して保持可能であり、かつ、被固定部材の傾き角度及び傾き方向の再調整が容易である接合構造を提供することを目的とする。 The present invention has been made in view of the above circumstances, and can adjust the tilt angle and tilt direction of the fixed member relative to the fixed member, and can stabilize the fixed member regardless of the tilt angle and tilt direction. It is an object of the present invention to provide a joint structure that can be held and can be easily readjusted in the inclination angle and the inclination direction of the fixed member.

　上記目的を達成するために、第１に本発明は、第一凸曲面を有し固定部材に連結される受け座部と、前記第一凸曲面に面接触しつつ摺動可能な第一凹曲面及び該第一凹曲面の裏面側の第二凸曲面を有する椀状部材と、前記第二凸曲面の中央から突出し被固定部材に連結される軸部材と、前記第二凸曲面に面接触する第二凹曲面を有し前記受け座部に対して前記椀状部材を押し付け固定する押付部材と、前記第一凹曲面の摺動範囲よりも外側で前記押付部材を前記受け座部又は前記固定部材に締結する締結手段と、を備え、前記第一凸曲面、前記第一凹曲面、前記第二凸曲面及び前記第二凹曲面が略同心の略真球面状を呈していることを特徴とする接合構造を提供する（発明１）。 In order to achieve the above object, first, the present invention includes a receiving seat portion having a first convex curved surface and connected to a fixing member, and a first concave slidable while being in surface contact with the first convex curved surface. A surface-shaped member having a curved surface and a second convex curved surface on the back side of the first concave curved surface, a shaft member protruding from the center of the second convex curved surface and connected to a fixed member, and surface contact with the second convex curved surface A pressing member that has a second concave curved surface and presses and fixes the flange-shaped member against the receiving seat portion, and the pressing member is disposed outside the sliding range of the first concave curved surface. Fastening means for fastening to a fixing member, wherein the first convex curved surface, the first concave curved surface, the second convex curved surface, and the second concave curved surface have a substantially concentric substantially spherical shape. (Invention 1).

　上記発明（発明１）によれば、押付部材を受け座部又は固定部材に対して締結している位置が椀状部材の第一凹局面の摺動範囲よりも外側であることにより、接合構造の上部に被固定部材が載せられた状態であっても、押付部材を受け座部又は固定部材に締結する締結手段を緩めることにより椀状部材を受け座部と押付部材との間で摺動させ、固定部材に対する軸部材の傾き角度及び傾き方向を調整できるため、固定部材に対して被固定部材を取り付ける傾き角度及び傾き方向を調整することができる。また、傾き角度及び傾き方向を調整するために、被固定部材を接合構造から取り外す必要がないため、被固定部材は安定的に保持され、何度でも再調整が容易である。 According to the above invention (Invention 1), the position where the pressing member is fastened to the seat portion or the fixing member is outside the sliding range of the first concave aspect of the hook-shaped member, whereby the joining structure Even when the fixed member is placed on the top of the slidable member, the hooked member is slid between the receiving part and the pressing member by loosening the fastening means for fastening the pressing member to the receiving part or the fixing member. Since the tilt angle and tilt direction of the shaft member with respect to the fixing member can be adjusted, the tilt angle and tilt direction for attaching the fixed member to the fixing member can be adjusted. Further, since it is not necessary to remove the member to be fixed from the joining structure in order to adjust the inclination angle and the inclination direction, the member to be fixed is stably held, and readjustment is easy any number of times.

　上記発明（発明３）によれば、第一挟持部と第二挟持部とが締緩自在に構成されていることにより、第一挟持部及び第二挟持部による軸部材及び被固定部材の挟持状態を解除することができるため、被固定部材を完全に接合構造から取り外すことなく軸部材の雄ねじ部材及び雌ねじ部材の相対回転が可能になる。それにより、一旦決めた軸部材の傾き角度及び傾き方向を維持したまま固定部材に対する被固定部材の高さのみを容易に微調整・再調整することができる。 According to the said invention (invention 3), since the 1st clamping part and the 2nd clamping part are comprised so that loosening is possible, clamping of the shaft member and to-be-fixed member by a 1st clamping part and a 2nd clamping part Since the state can be released, the male screw member and the female screw member of the shaft member can be relatively rotated without completely removing the member to be fixed from the joining structure. Thereby, only the height of the fixed member relative to the fixing member can be easily finely adjusted / re-adjusted while maintaining the inclination angle and the inclination direction of the shaft member once determined.

　上記発明（発明１～３）においては、前記受け座部が、前記第一凸曲面を有する受け部材と、該受け部材を取り付けて前記固定部材に連結する取付部材とを備え、前記受け部材を前記取付部材に取り付ける位置を変えることによって、前記固定部材に対する前記第一凸曲面の相対的な位置の調整が可能であることが好ましい（発明４）。 In the above inventions (Inventions 1 to 3), the receiving seat portion includes a receiving member having the first convex curved surface, and an attachment member to which the receiving member is attached and coupled to the fixing member. It is preferable that the relative position of the first convex curved surface with respect to the fixing member can be adjusted by changing the position of attachment to the attachment member (Invention 4).

　上記発明（発明４）によれば、固定部材に対する被固定部材の傾き角度及び傾き方向の調整に加えて、受け部材を取付部材に取り付ける位置を変えるという簡易な操作だけで固定部材に対する被固定部材の平面位置の調整も容易に行うことができる。 According to the above invention (Invention 4), in addition to the adjustment of the tilt angle and tilt direction of the fixed member with respect to the fixed member, the fixed member with respect to the fixed member can be simply operated by changing the position where the receiving member is attached to the mounting member.

In this embodiment, the support pile 8 is erected by being driven into the ground 7 so that the opening side comes in the longitudinal direction of the horizontal beam 92 (that is, the east-west direction) instead of the longitudinal direction of the vertical beam 91 (that is, the north-south direction). ing.

　コネクタ１は、図４～６に示すように、受け座部１０、椀状部材２０、軸部材３０、押付部材４０及び挟持部材５０を組み合わせて構成され、受け座部１０が支持杭８に連結され、軸部材３０が挟持部材５０を介して太陽光発電パネル設置用架台の上部構造９の縦桟９１に連結されることにより、太陽光発電パネル設置用架台の上部構造９を支持杭８に固定するものである。本実施形態のコネクタ１の材質は鉄であり、例えば鋼板をプレス加工することによって製造されるが、これに限られるものではない。 As shown in FIGS. 4 to 6, the connector 1 is configured by combining a receiving seat portion 10, a bowl-shaped member 20, a shaft member 30, a pressing member 40 and a clamping member 50, and the receiving seat portion 10 is connected to the support pile 8. Then, the shaft member 30 is connected to the vertical beam 91 of the upper structure 9 of the solar panel installation stand via the sandwiching member 50, so that the upper structure 9 of the solar panel installation base is used as the support pile 8. It is to be fixed. The material of the connector 1 of this embodiment is iron, and is manufactured by, for example, pressing a steel plate, but is not limited thereto.

　なお、図４はコネクタ１の使用状態を示す説明図であり、図１中の一つのコネクタ１周辺部分を拡大したものである。実際に太陽光発電パネル設置用架台の上部構造９を設置する際は、主に南側に太陽光発電パネルが向くように角度を付けて支持杭８に固定される。そのため図４においては、太陽光発電パネル設置用架台の上部構造９を支持杭８に対して所定の角度でコネクタ１によって固定する様子が示されている。また、説明の都合上、地盤７は平坦とし、支持杭８は鉛直方向に立設するものとしているが、実際には傾斜地において支持杭８を地盤７に対して角度を付けて打ち込むこともある。一方、図４とは異なり、図５及び６においては、コネクタ１の構造を説明するに適した図とするために、支持杭８に対して角度を付けずに太陽光発電パネル設置用架台の上部構造９を固定する様子を示している。すなわち、太陽光発電パネル設置用架台の上部構造９の縦桟９１は支持杭８上に水平に固定されている。 FIG. 4 is an explanatory view showing the usage state of the connector 1, and is an enlarged view of the peripheral portion of one connector 1 in FIG. When actually installing the superstructure 9 for the solar panel installation stand, the solar panel is mainly fixed to the support pile 8 at an angle so that the solar panel faces the south side. Therefore, in FIG. 4, a state in which the upper structure 9 of the solar panel mounting base is fixed to the support pile 8 by the connector 1 at a predetermined angle is shown. In addition, for the convenience of explanation, the ground 7 is flat and the support pile 8 is erected in the vertical direction, but actually, the support pile 8 may be driven at an angle with respect to the ground 7 on an inclined ground. . On the other hand, unlike FIG. 4, in FIGS. 5 and 6, in order to make the figure suitable for explaining the structure of the connector 1, the photovoltaic power generation panel installation platform is not inclined with respect to the support pile 8. A state in which the upper structure 9 is fixed is shown. That is, the vertical beam 91 of the upper structure 9 of the gantry for installing the photovoltaic power generation panel is fixed horizontally on the support pile 8.

　挟持部材５０は、軸部材３０を太陽光発電パネル設置用架台の上部構造９へと連結するための部材であり、第一挟持板部材５１と第二挟持板部材５２とから構成される。第一挟持板部材５１と第二挟持板部材５２との間に、軸部材３０の雌ねじ部材３２と太陽光発電パネル設置用架台の上部構造９の縦桟９１とが締緩自在に挟持される。本実施形態においては第一挟持板部材５１と第二挟持板部材５２とは全く同一の形状を有するため、第一挟持板部材５１についてのみその構造を説明する。 The sandwiching member 50 is a member for connecting the shaft member 30 to the upper structure 9 of the gantry for installing the photovoltaic power generation panel, and includes a first sandwiching plate member 51 and a second sandwiching plate member 52. Between the 1st clamping board member 51 and the 2nd clamping board member 52, the internal thread member 32 of the shaft member 30 and the vertical beam 91 of the upper structure 9 of a photovoltaic power generation panel installation stand are clamped freely. . In the present embodiment, since the first clamping plate member 51 and the second clamping plate member 52 have exactly the same shape, only the structure of the first clamping plate member 51 will be described.

　第一挟持部材５１は、縦桟９１を挟持するための平板形状の桟接触部５１１と、桟接触部５１１の下側に位置し、軸部材３０の雌ねじ部材３２の形状に対応する略半円柱形状の窪みが設けられた軸接触部５１４とを有している。また、縦桟９１を挟持したときに縦桟９１が上方向にずれて抜けることがないように、桟接触部５１１の上端部は内側に向かって折り曲げられて返し５１２を構成しており、当該返し５１２は縦桟９１を挟持したときに縦桟９１の係止部９１１を覆うような形状となっている。軸接触部５１４の両側部には、第一挟持板部材５１と第二挟持板部材５２とを対向させ、縦桟９１及び雌ねじ部材３２を間に挟んで固定するためのボルト・ナット６３を通す丸孔５１３が設けられている。ボルト・ナット６３をきつく締めることにより、第一挟持板部材５１と第二挟持板部材５２とよって縦桟９１及び雌ねじ部材３２を間に挟持して固定状態となり、ボルト・ナット６３を緩めることにより、固定状態が解除される。ボルト・ナット６３を緩めて固定状態が解除された場合にも雌ねじ部材３２が第一挟持板部材５１及び第二挟持板部材５２の間から抜けることがないように、軸接触部５１４には、雌ねじ部材３２を挟持したときに雌ねじ部材３２の頭部３２１が嵌合する溝５１５が形成されている。 The first clamping member 51 is located on the lower side of the flat bar contact portion 511 for holding the vertical cross beam 91 and the cross bar contact portion 511, and is a substantially semi-cylindrical shape corresponding to the shape of the female screw member 32 of the shaft member 30. And a shaft contact portion 514 provided with a shaped recess. Further, the upper end portion of the crosspiece contact portion 511 is bent inward so as to prevent the vertical crosspiece 91 from slipping upward and being pulled out when the vertical crosspiece 91 is sandwiched, and a return 512 is formed. The return 512 is shaped to cover the locking portion 911 of the vertical beam 91 when the vertical beam 91 is sandwiched. On both sides of the shaft contact portion 514, the first clamping plate member 51 and the second clamping plate member 52 are opposed to each other, and a bolt and nut 63 for fixing the vertical beam 91 and the female screw member 32 therebetween is passed. A round hole 513 is provided. By tightening the bolts and nuts 63, the first sandwiching plate member 51 and the second sandwiching plate member 52 sandwich the vertical beam 91 and the female screw member 32 between them, and the bolts and nuts 63 are loosened. The fixed state is released. In order to prevent the female screw member 32 from coming out from between the first clamping plate member 51 and the second clamping plate member 52 even when the bolt and nut 63 are loosened and the fixed state is released, the shaft contact portion 514 includes: A groove 515 into which the head 321 of the female screw member 32 is fitted when the female screw member 32 is sandwiched is formed.

　以上に説明したコネクタ１を構成する各部材を組み合わせ、コネクタ１を使用して縦桟９１を支持杭８に固定する方法を説明する。まず、取付部材１２ａ，１２ｂの受け部材取付部１２３ａ，１２３ｂが支持杭８の上端から外側に位置するように、取付部材１２ａ，１２ｂの支持杭取付孔１２２ａ，１２２ｂと支持杭８の取付部材連結孔８２とをボルト・ナット６０で締めて取付部材１２ａ，１２ｂを支持杭８に取り付ける。支持杭取付孔１２２ａ，１２２ｂは角孔形状を有しているため、この角孔形状に対応した角根丸頭ボルト６０を用いると、ボルト・ナットの締結作業が容易になる。支持杭８の取付部材連結孔８２は両側面にそれぞれ三つずつ穿設されているが、求められる縦桟９１の設置高さに合わせて三つの中から任意に選択することができる。 A method of fixing the vertical beam 91 to the support pile 8 using the connector 1 by combining the members constituting the connector 1 described above will be described. First, the support

member attachment portions

122a and 122b of the

attachment members

12a and 12b are connected to the attachment members of the support pile 8 so that the receiving

member attachment portions

123a and 123b of the

attachment members

12a and 12b are located outward from the upper end of the support pile 8. The mounting

members

12 a and 12 b are attached to the support pile 8 by tightening the holes 82 with bolts and nuts 60. Since the support

pile mounting holes

122a and 122b have a square hole shape, the use of the round-headed round head bolt 60 corresponding to the square hole shape facilitates the bolt / nut fastening operation. The attachment member connecting holes 82 of the support pile 8 are formed in three on each side, but can be arbitrarily selected from three according to the required installation height of the vertical beam 91.

　続いて、受け部材取付孔１２４ａ，１２４ｂ上に取付部材締結孔１１３ａ，１１３ｂが来るように、取付部材１２ａ，１２ｂの受け部材取付部１２３ａ，１２３ｂ上に受け部材１１を載置し、受け部材取付孔１２４ａ，１２４ｂと取付部材締結孔１１３ａ，１１３ｂとをボルト・ナット６１で締めて受け部材１１を取付部材１２ａ，１２ｂに取り付ける。このとき受け部材１１は、受け部材１１の各辺が支持杭８の各辺と平行になるように、取付部材１２ａ，１２ｂに取り付けることになるが、取付部材締結孔１１３ａ，１１３ｂが矩形長孔形状に形成されていることにより、受け部材１１の支持杭８に対する東西方向の取り付け位置はこの取付部材締結孔１１３ａ，１１３ｂの東西方向長さの範囲内で自由に動かすことができる。また、受け部材取付孔１２４ａ，１２４ｂも長角孔形状に形成されているため、受け部材１１の支持杭８に対する南北方向の取り付け位置もこの受け部材取付孔１２４ａ，１２４ｂの南北方向長さの範囲内で調整することが可能となっている。なお、受け部材１１の支持杭８に対する南北方向の取り付け位置の調整幅は東西方向の調整幅より小さいが、南北方向の位置調整は縦桟９１を挟持部材５０に挟持させる位置自体を動かすことによってより広範囲に調整可能である。 Subsequently, the receiving member 11 is placed on the receiving

member mounting portions

123a and 123b of the mounting

members

12a and 12b so that the mounting

member fastening holes

113a and 113b come on the receiving

member mounting holes

124a and 124b. The receiving member 11 is attached to the

attachment members

12a and 12b by tightening the

holes

124a and 124b and the attachment

member fastening holes

113a and 113b with bolts and nuts 61. At this time, the receiving member 11 is attached to the

attachment members

12a and 12b so that each side of the receiving member 11 is parallel to each side of the support pile 8, but the attachment

member fastening holes

113a and 113b are rectangular long holes. Due to the shape, the mounting position of the receiving member 11 with respect to the support pile 8 in the east-west direction can be freely moved within the range of the east-west length of the mounting

member fastening holes

113a, 113b. In addition, since the receiving

member mounting holes

124a and 124b are also formed in an oblong hole shape, the mounting position of the receiving member 11 with respect to the support pile 8 in the north-south direction is also within the range of the length of the receiving

member mounting holes

124a and 124b in the north-south direction. It is possible to adjust within. Although the adjustment width of the attachment position of the receiving member 11 in the north-south direction with respect to the support pile 8 is smaller than the adjustment width in the east-west direction, the position adjustment in the north-south direction is performed by moving the position itself that holds the vertical beam 91 between the holding members 50. A wider range of adjustment is possible.

　このように、本実施形態においては、受け部材１１を取付部材１２ａ，１２ｂに取り付ける位置を変えることによって、支持杭８に対する受け部材１１や受け部材１１に設けられた椀状部材接触面１１１の相対的な位置の調整が可能となっている。そのため、受け部材１１を取付部材１２ａ，１２ｂに取り付ける位置を変えるという簡易な操作だけで支持杭８に対する太陽光発電パネル設置用架台の上部構造９の平面位置の調整も容易に行うことができる。 Thus, in this embodiment, by changing the position where the receiving member 11 is attached to the attaching

members

12a and 12b, the relative position of the receiving member 11 and the hook-shaped member contact surface 111 provided on the receiving member 11 with respect to the support pile 8 is increased. Position adjustment is possible. Therefore, it is possible to easily adjust the planar position of the upper structure 9 of the solar panel mounting base with respect to the support pile 8 only by a simple operation of changing the position where the receiving member 11 is attached to the

　次に、受け部材１１の椀状部材接触面１１１に椀状部材２０の受け座部接触面２１が当接するように、受け部材１１上に椀状部材２０を載置し、椀状部材２０から突出する軸部材３０（雄ねじ部材３１に雌ねじ部材３２を螺合させた状態にしておく）が開口部４２から突き出すように、更に押付部材４０を椀状部材２０及び受け部材１１上に載置する。この結果、押付部材４０と受け部材１１との間に椀状部材２０が挟み込まれた状態となり、押付部材４０の椀状部材押付面４１が椀状部材２０の押付部材接触面２２に面接触し、椀状部材２０の受け部材接触面２１が受け部材１１の椀状部材接触面１１１に面接触する。このとき、押付部材の締結孔４３１ａが受け部材１１の押付部材締結孔１１４a上に来るように、押付部材の締結孔４３１ｂ，４３１ｃが受け部材１１の押付部材締結孔１１４ｂ，１１４ｃそれぞれの上に来るように、押付部材４０の載置位置を決め、締結孔４３１ａ，４３１ｂ，４３１ｃと押付部材締結孔１１４ａ，１１４ｂ，１１４ｃとをボルト・ナット６２で締めて押付部材４０を受け座部１０の受け部材１１に締結する。ここまでの作業を各支持杭８に対して繰り返し、挟持部材５０を除くコネクタ１を各支持杭８の上部に取り付ける。 Next, the hook-shaped member 20 is placed on the receiving member 11 so that the receiving seat contact surface 21 of the hook-shaped member 20 contacts the hook-shaped member contact surface 111 of the receiving member 11. The pressing member 40 is further placed on the flange-shaped member 20 and the receiving member 11 so that the protruding shaft member 30 (with the female screw member 32 screwed to the male screw member 31) protrudes from the opening 42. . As a result, the hook member 20 is sandwiched between the pressing member 40 and the receiving member 11, and the hook member pressing surface 41 of the pressing member 40 comes into surface contact with the pressing member contact surface 22 of the hook member 20. The receiving member contact surface 21 of the hook-shaped member 20 comes into surface contact with the hook-shaped member contact surface 111 of the receiving member 11. At this time, the fastening holes 431b and 431c of the pressing member are respectively on the pressing member fastening holes 114b and 114c of the receiving member 11 so that the fastening hole 431a of the pressing member is on the pressing member fastening hole 114a of the receiving member 11. Thus, the mounting position of the pressing member 40 is determined, and the

fastening holes

431a, 431b, 431c and the pressing

member fastening holes

114a, 114b, 114c are tightened with the bolts and nuts 62 to receive the pressing member 40 and the receiving member of the seat portion 10 11 to fasten. The operation so far is repeated for each support pile 8, and the connector 1 excluding the clamping member 50 is attached to the upper portion of each support pile 8.

　続いて、軸部材３０の雌ねじ部材３２の頭部３２１が第一挟持板部材５１及び第二挟持板部材５２の溝５１５に嵌合するように第一挟持板部材５１と第二挟持板部材５２とで軸部材３０を挟持し、縦桟９１を第一挟持板部材５１及び第二挟持板部材５２の桟接触部５１１の間に通した状態で、第一挟持板部材５１及び第二挟持板部材５２の丸孔５１３をボルト・ナット６３で締める。この作業を各支持孔８において繰り返し、支持杭８上に複数の縦桟９１を平行に並べて取り付けていく。 Subsequently, the first clamping plate member 51 and the second clamping plate member 52 so that the head portion 321 of the female screw member 32 of the shaft member 30 is fitted in the grooves 515 of the first clamping plate member 51 and the second clamping plate member 52. The first clamping plate member 51 and the second clamping plate in a state where the shaft member 30 is clamped between the first clamping plate member 51 and the second clamping plate member 52. The round hole 513 of the member 52 is tightened with the bolt and nut 63. This operation is repeated in each support hole 8, and a plurality of vertical bars 91 are mounted in parallel on the support pile 8.

　縦桟９１を平行に並べて取り付けた後、今度は縦桟９１上に複数の横桟９２を平行に並べ、連結金具、ねじ止め等の公知の固定手段によって縦桟９１と横桟９２とを固定して太陽光発電パネル設置用架台の上部構造９を支持杭８上で組み立てる。 After the vertical bars 91 are mounted in parallel, a plurality of horizontal bars 92 are arranged in parallel on the vertical bars 91, and the vertical bars 91 and the horizontal bars 92 are fixed by known fixing means such as connecting brackets and screws. Then, the upper structure 9 of the mount for installing the photovoltaic power generation panel is assembled on the support pile 8.

　ここで、押付部材４０を受け座部１０の受け部材１１に対して締結している位置は、図６に示すように、椀状部材２０の受け座部接触面２１の摺動範囲よりも外側にある。このように押付部材４０を受け座部１０の受け部材１１に対して締結していることにより、コネクタ１の上部に太陽光発電パネル設置用架台の上部構造９が載せられた状態であっても、ボルト・ナット６２を緩めることにより椀状部材２０を受け座部１０と押付部材４０との間で摺動させ、支持杭８に対する軸部材３０の傾き角度及び傾き方向を調整できるため、支持杭８に対して太陽光発電パネル設置用架台の上部構造９を取り付ける傾き角度及び傾き方向を調整することができる。傾き角度及び傾き方向を調整するために、太陽光発電パネル設置用架台の上部構造９をコネクタ１から取り外す必要がないため、太陽光発電パネル設置用架台の上部構造９は安定的に保持され、何度でも再調整が容易である。 Here, the position where the pressing member 40 is fastened to the receiving member 11 of the receiving portion 10 is outside the sliding range of the receiving portion contact surface 21 of the bowl-shaped member 20 as shown in FIG. It is in. Thus, even if it is in the state by which the upper structure 9 of the mount for photovoltaic power generation panel installation was mounted on the upper part of the connector 1 by fastening with respect to the receiving member 11 of the receiving part 10 by the pressing member 40 Since the flanged member 20 is slid between the seat 10 and the pressing member 40 by loosening the bolts and nuts 62, the inclination angle and the inclination direction of the shaft member 30 with respect to the support pile 8 can be adjusted. The inclination angle and the inclination direction for attaching the upper structure 9 of the solar power panel installation base to 8 can be adjusted. In order to adjust the tilt angle and the tilt direction, it is not necessary to remove the upper structure 9 of the solar panel installation stand from the connector 1, so that the upper structure 9 of the solar panel installation base is stably held, It is easy to readjust again and again.

　また、第一挟持板部材５１と第二挟持板部材５２とはボルト・ナット６３によって締緩自在に連結されていることにより、当該ボルト・ナット６３を緩めることにより第一挟持板部材５１及び第二挟持板部材５２による軸部材３０及び縦桟９２の挟持状態を解除することができる。このように挟持状態を解除すると、太陽光発電パネル設置用架台の上部構造９を完全にコネクタ１から取り外すことなく軸部材３０の雄ねじ部材３１及び雌ねじ部材３２の相対回転が可能になるため、一旦決めた傾き角度及び傾き方向を維持したまま支持杭８に対する太陽光発電パネル設置用架台の上部構造９の設置高さのみを容易に再調整・微調整することができる。 Further, since the first clamping plate member 51 and the second clamping plate member 52 are connected to each other by bolts and nuts 63, the bolts and nuts 63 are loosened to loosen the first clamping plate member 51 and the second clamping plate member 51. The clamping state of the shaft member 30 and the vertical beam 92 by the two clamping plate members 52 can be released. When the clamping state is released in this manner, the male screw member 31 and the female screw member 32 of the shaft member 30 can be rotated relative to each other without completely removing the upper structure 9 of the solar panel mounting base from the connector 1. Only the installation height of the upper structure 9 of the gantry for installing the solar power generation panel with respect to the support pile 8 can be easily readjusted and finely adjusted while maintaining the determined inclination angle and inclination direction.
