そして、作業者が現場で、フックを起立させた状態で金物基体を床パネルに設けた孔に上方から挿通し、フックを床フランジの下方に突出させ、且つ、座金部材を床フランジの上面側に当接させる。   Then, the worker inserts the metal base from above into the hole provided in the floor panel with the hook standing upright on the site, projects the hook downward from the floor flange, and the washer member on the upper surface side of the floor flange. Abut.

フックは孔通過後に、自重などで回動して横向きに開いて後端部が金物基体の下端面に当って回動が規制されて固定された状態となる。   After passing through the hole, the hook is rotated by its own weight and opened sideways, and the rear end of the hook hits the lower end surface of the metal base and the rotation is restricted and fixed.

この状態で、作業者は、ボルトの頭部を回転操作し、座金部材とフックとの間隔の距離を小さくして、フックを上フランジの下面に当接し、固定対象である床パネルと梁（上フランジ）を、座金部材とフックとで挟み込む。   In this state, the operator rotates the head of the bolt, reduces the distance between the washer member and the hook, abuts the hook against the lower surface of the upper flange, and fixes the floor panel and beam ( The upper flange) is sandwiched between the washer member and the hook.

このようにして、作業者は固定対象の上面側からの作業のみで固定金物を用いた固定対象の挟持による固定を行うことができる。   In this way, the operator can perform fixing by holding the fixing object using the fixing hardware only from the upper surface side of the fixing object.

The bolt insertion portion 20 includes a first bolt insertion portion 21 that allows insertion of the bolt 9 in the standing posture of the lower clamping portion 5 and a second bolt insertion portion that permits insertion of the bolt 9 in the lateral orientation of the lower clamping portion 5. 22 and a communication portion 23 that allows the bolt 9 to rotate so that the posture in which the bolt 9 is inserted into the second bolt insertion portion 22 is changed from the posture in which the bolt 9 is inserted into the first bolt insertion portion 21. The

本実施形態では、下挟持部５は、鋼板を折り曲げて形成した細長部材１５により構成される。   In this embodiment, the lower clamping part 5 is comprised by the elongate member 15 formed by bending a steel plate.

細長部材１５は、図１、図２、図３に示されるように、一対の側面片１５ａ、側面片１５ａ同士を一体に連続する上面片１５ｂを備える。この細長部材１５の側面片１５ａ間に、長手方向に沿ってボルト９の挿通（下挟持部５の起立姿勢におけるボルト９の挿通）を許容する第１ボルト挿通部２２が形成されている。   As shown in FIGS. 1, 2, and 3, the elongate member 15 includes a pair of side surface pieces 15 a and an upper surface piece 15 b that continuously connects the side surface pieces 15 a together. Between the side piece 15a of this elongate member 15, the 1st bolt insertion part 22 which accept | permits the insertion of the volt | bolt 9 (insertion of the volt | bolt 9 in the standing posture of the lower clamping part 5) is formed along the longitudinal direction.

細長部材１５を上面片１５ｂが上面側となるように横向き姿勢にした状態で、細長部材１５の上面の長手方向の一端部から他端部にかけて、順に、上面片１５ｂで一体に連結した部位、第１開口部１５ｃ、第２開口部１５ｄとなっている。   In a state where the elongated member 15 is in a lateral posture so that the upper surface piece 15b is on the upper surface side, a portion integrally connected by the upper surface piece 15b in order from one end portion to the other end portion of the elongated member 15 in the longitudinal direction; A first opening 15c and a second opening 15d are formed.

上面片１５ｂは、対向する細長い側面片１５ａの巾方向の一端で且つ長手方向の略片側分部同士を一体に連続している。   The upper surface piece 15b is one end in the width direction of the elongated side surface piece 15a facing each other, and substantially one side portion in the longitudinal direction is continuously integrated.

第１開口部１５ｃは細長部材１５の長手方向の略中央部の上面が開口しているだけでなく、側面片１５ａの上部を切除することで、側面上部が開口させてある。   The first opening portion 15c is not only opened at the upper surface of the substantially central portion in the longitudinal direction of the elongated member 15, but is also opened at the upper side surface by cutting out the upper portion of the side piece 15a.

したがって両側面片１５ａは、第１開口部１５ｃ部分においては、巾が短くなっている。   Therefore, the width of the side surface pieces 15a is shortened in the first opening 15c portion.

この側面片１５ａの巾が狭くなった部分の第１開口部１５ｃ側の端縁部には内側斜め下方に向けて傾斜片１５ｅが一体に連出されている。   An inclined piece 15e is integrally extended to the end edge portion on the first opening 15c side of the portion where the width of the side piece 15a is narrowed toward the inner side obliquely downward.

上記一対の傾斜片１５ｅは略逆ハ字状に対向して受け部１５ｆが形成される。   The pair of inclined pieces 15e are opposed to each other in a substantially inverted C shape, and a receiving portion 15f is formed.

細長部材１５の内部の両側面片１５ａ、上面片１５ｂ、受け部１５ｆで囲まれた部分が、第１ボルト挿通部２１となっている。   A portion surrounded by the both side surface pieces 15 a, the upper surface piece 15 b, and the receiving portion 15 f inside the elongated member 15 is a first bolt insertion portion 21.

第２開口部１５ｄは上下方向に開口するだけでなく、長手方向の一端部が第１開口部１５ｃに連通するように開口させてあり、また、長手方向の他端部も開口させてある。   The second opening 15d is not only opened in the vertical direction, but is opened so that one end in the longitudinal direction communicates with the first opening 15c, and the other end in the longitudinal direction is also opened.

なお、添付図面に示す実施形態では、両側面片１５ａの端縁部から内側に補強用の縁片１５ｇを突出させて、両縁片１５ｇ間を第２開口部１５ｄとして形成してあるが、必ずしも縁片１５ｇを設けなくてもよい。   In the embodiment shown in the attached drawings, a reinforcing edge piece 15g is projected inward from the end edge of both side pieces 15a, and the space between both edge pieces 15g is formed as a second opening 15d. It is not always necessary to provide the edge piece 15g.

第１開口部１５ｃ、第２開口部１５ｄの開口巾寸法はボルト９の軸部分の直径よりも大きく設定される。   The opening width dimension of the first opening 15c and the second opening 15d is set larger than the diameter of the shaft portion of the bolt 9.

上面片１５ｂの第１開口部１５ｃ側の端部には第１ボルト挿通部２１に開口する細長切込み部１５ｈが形成されており、この細長切込み部１５ｈが、下挟持部５の横向き姿勢におけるボルト９の挿通を許容する第２ボルト挿通部２２となっている。   An elongated cut portion 15h that opens to the first bolt insertion portion 21 is formed at the end of the upper surface piece 15b on the first opening portion 15c side, and this elongated cut portion 15h is a bolt in the lateral orientation of the lower clamping portion 5 9 is a second bolt insertion portion 22 that allows 9 insertion.

細長切込み部１５ｈの巾寸法は、ボルト９の軸部分の直径より大きく、ボルト９に螺合するナット１８の対面寸法より小さく形成されている。   The width dimension of the elongated cut portion 15h is larger than the diameter of the shaft portion of the bolt 9 and smaller than the facing dimension of the nut 18 screwed into the bolt 9.

また、第１開口部１５ｃと第２開口部１５ｄにより、ボルト９が第１ボルト挿通部２１に挿通された姿勢から第２ボルト挿通部２２に挿通される姿勢となるようにボルト９の回動を許容する連通部２３が構成される。   Further, the bolt 9 is rotated by the first opening 15c and the second opening 15d so that the bolt 9 is inserted into the second bolt insertion part 22 from the attitude inserted through the first bolt insertion part 21. The communication part 23 which permits the above is configured.

この連通部２３は第１ボルト挿通部２１に連通され、また、第２ボルト挿通部２２である細長切込み部１５ｈに連通されている。   The communication portion 23 communicates with the first bolt insertion portion 21 and also communicates with an elongated cut portion 15 h that is the second bolt insertion portion 22.

細長部材１５には当り部１９が設けられている。この当り部１９は細長部材１５の長手方向の略中間部の下部に設けられる。   The elongated member 15 is provided with a contact portion 19. The contact portion 19 is provided at a lower portion of a substantially intermediate portion in the longitudinal direction of the elongated member 15.

ボルト９は、座金部材４ａの孔４ｂに挿通した状態で、細長部材１５の第１ボルト挿通部２１の一端、つまり、両側面片１５ａ間の長手方向の一端（第１開口部１５ｃ側の端部）から細長部材１５内に差し込まれる。ここで、ボルト９は、受け部１５ｆと上面片１５ｂの間を通過させられ、先端部にナット１８が螺合される。   The bolt 9 is inserted into the hole 4b of the washer member 4a, and is connected to one end of the first bolt insertion portion 21 of the elongated member 15, that is, one end in the longitudinal direction between the side surface pieces 15a (the end on the first opening 15c side). Part) into the elongated member 15. Here, the bolt 9 is passed between the receiving portion 15f and the upper surface piece 15b, and the nut 18 is screwed to the tip portion.

ナット１８は細長切込み部１５ｈの巾よりも大きいものが用いられる。ここで、ナット１８は、両側面片１５ａ間に配置した状態で、両側面片１５ａ間で回転できないように、対面寸法が両側面片１５ａ間の寸法より小さく、且つ、対角寸法が両側面片１５ａ間の寸法より大きいものを用いるのが好ましい。   The nut 18 is larger than the width of the elongated cut portion 15h. Here, the nut 18 has a facing dimension smaller than a dimension between the side face pieces 15a so that the nut 18 cannot rotate between the both side face pieces 15a in a state where the nut 18 is disposed between the both side face pieces 15a, and the diagonal dimension is set to the both side faces. It is preferable to use a larger one than the dimension between the pieces 15a.

本実施形態の固定金物１１は、図１、図４（ｂ）のように、細長部材１５をボルト９に沿うように起立させ、当り部１９にナット１８を当てることで、細長部材１５が起立姿勢でボルト９から下方に抜け落ちない。   As shown in FIGS. 1 and 4B, the fixed hardware 11 according to the present embodiment erects the elongate member 15 along the bolt 9, and applies the nut 18 to the contact portion 19, so that the elongate member 15 erects. It does not fall down from the bolt 9 in the posture.

この場合、細長部材１５の重心位置は、ナット１８が当り部１９に当っている位置、または、ナット１８が当り部１９に当っている状態で細長部材１５を図４（ｂ）において矢印で示す方向（図では反時計回り方向）に回転させることができる位置に設定されている。また、この細長部材１５の重心位置は、細長部材１５を横向き姿勢にした状態で、細長部材１５の重心を通る垂直線が細長切込み部１５ｈ内を通るように設定されている。   In this case, the position of the center of gravity of the elongated member 15 is indicated by an arrow in FIG. 4B when the nut 18 is in contact with the contact portion 19 or the nut 18 is in contact with the contact portion 19. It is set at a position where it can be rotated in the direction (counterclockwise in the figure). The center of gravity of the elongate member 15 is set such that a vertical line passing through the center of gravity of the elongate member 15 passes through the elongate cut portion 15h in a state in which the elongate member 15 is in the horizontal posture.

したがって、細長部材１５がボルト９に沿った起立姿勢で、自重又は振動等の外力を加えることで、細長部材１５はナット１８と当り部１９の当接部分を中心に回動を開始する。細長部材１５が回動することで、ボルト９が連通部２３内を回動して、図２、図３、図５に示されるように、細長切込み部１５ｈを挿通する状態となり、ナット１８が細長切込み部１５ｈの下面側に当接する。この状態で、細長部材１５がナット１８の当接部分を中心にして自由状態で左右のバランスが取れた横向き姿勢で停止する。   Therefore, the elongated member 15 starts to rotate around the contact portion between the nut 18 and the contact portion 19 by applying an external force such as its own weight or vibration while the elongated member 15 is standing along the bolt 9. As the elongated member 15 is rotated, the bolt 9 is rotated in the communication portion 23 to be inserted through the elongated cut portion 15h as shown in FIGS. It contacts the lower surface side of the elongated cut portion 15h. In this state, the elongated member 15 stops in a lateral posture in which the left and right balance is achieved in a free state around the contact portion of the nut 18.

細長部材１５の横向き姿勢で、長手方向の両端部上端が、それぞれ第１下挟持部５ａ、第２下挟持部５ｂとなる。   In the lateral orientation of the elongated member 15, the upper ends of both end portions in the longitudinal direction become the first lower holding portion 5a and the second lower holding portion 5b, respectively.

この図２、図３、図５に示される横向き姿勢で停止している状態の下挟持部５に外力が作用すると、ナット１８が細長切込み部１５ｈの裏面に当っている部分を中心にシーソ揺動可能となっている。つまり、下挟持部５は、自由状態で左右のバランスが取れて横向き姿勢で停止する状態で、この横向き姿勢を超えて更に回動可能になされている。   When an external force is applied to the lower clamping part 5 in the state of being stopped in the lateral orientation shown in FIGS. 2, 3 and 5, the seesaw swings around the part where the nut 18 hits the back surface of the elongated cut part 15h. It is possible to move. That is, the lower clamping unit 5 is further rotatable beyond the horizontal posture in a state where the left and right are balanced in a free state and stopped in the horizontal posture.

上記の構成の固定金物１１を用いて固定対象１を挟持する。   The fixed object 1 is clamped using the fixed hardware 11 having the above-described configuration.

添付図面においては固定対象１が、Ｈ型鋼のような型鋼よりなる梁１３と、この梁１３の上フランジ１３ａに載置されたＡＬＣなどの床パネル１４である場合の例が示されている。つまり、本例は、固定金物１１を用いて、固定対象１の一つの構成要素である床パネル１４と、固定対象の他の構成要素である梁１３が挟持固定される例である。   In the attached drawings, an example is shown in which the fixing object 1 is a beam 13 made of steel such as H-shaped steel and a floor panel 14 such as ALC mounted on the upper flange 13a of the beam 13. That is, this example is an example in which the fixed panel 11 is used to sandwich and fix the floor panel 14 that is one component of the fixation target 1 and the beam 13 that is another component of the fixation target.

図４に示されるように、床パネル１４には上フランジ１３ａの先端に隣接した位置に上下に貫通する孔２が形成され、この孔２は小径孔部２ａと小径孔部２ａの上端に連通する大径孔部２ｂで構成されている。   As shown in FIG. 4, the floor panel 14 has a hole 2 penetrating vertically at a position adjacent to the tip of the upper flange 13a. The hole 2 communicates with the small diameter hole 2a and the upper end of the small diameter hole 2a. The large-diameter hole portion 2b is configured.

本実施形態の固定金物１１を用いて固定対象１を挟持するには以下のようにして行われる。   In order to clamp the fixed object 1 using the fixed hardware 11 of this embodiment, it is performed as follows.

作業者は、まず、下挟持部５である細長部材１５を回動してボルト９に沿わせた状態で、床パネル１４の孔２に、図６〜図８の順序で固定金物１１を上方から挿通する。   First, the worker turns the elongate member 15 as the lower clamping portion 5 along the bolt 9 and puts the fixed hardware 11 in the hole 2 of the floor panel 14 in the order of FIGS. 6 to 8. Insert through.

起立姿勢の下挟持部５が孔２を通過して下挟持部５の上端が、固定対象１である床パネル１４の下面、上フランジ１３ａの下面より下方に至ると、下挟持部５が自重により側方に回動する。   When the lower sandwiching portion 5 in the standing posture passes through the hole 2 and the upper end of the lower sandwiching portion 5 reaches below the lower surface of the floor panel 14 and the lower surface of the upper flange 13a as the fixing object 1, the lower sandwiching portion 5 is self-weighted. To the side.

下挟持部５が側方に倒れると、図８のように、倒れた自由状態でナット１８が細長切込み部１５ｈの裏面に当っている部分を中心に左右のバランスが取れて横向き姿勢で停止する。   When the lower clamping part 5 falls to the side, as shown in FIG. 8, the left and right balance is achieved around the part where the nut 18 hits the back surface of the elongated cut part 15h in the fallen free state and stops in a sideways posture. .

また、下挟持部５が孔２を通過した後、上挟持部４、ボルト９の頭部９ａを大径孔部２ｂ内に嵌め込み、大径孔部２ｂの底面２ｃに載置する。   Moreover, after the lower clamping part 5 passes the hole 2, the upper clamping part 4 and the head 9a of the bolt 9 are fitted into the large diameter hole part 2b and placed on the bottom surface 2c of the large diameter hole part 2b.

作業者は、次に、床パネル１４の上方からボルト９の回転操作部１０である頭部９ａを回転操作し、ナット１８により下挟持部５を上方に押し上げ、上挟持部４と下挟持部５との間の間隔を小さくしていく。   Next, the operator rotates the head 9a, which is the rotation operation unit 10 of the bolt 9, from above the floor panel 14, and pushes the lower clamping unit 5 upward by the nut 18, so that the upper clamping unit 4 and the lower clamping unit The interval between 5 is reduced.

上挟持部４と下挟持部５との間の間隔を小さくしていくと、まず、下挟持部５の一端部の第１下挟持部５ａが上フランジ１３ａの下面に当接する。更に、上挟持部４と下挟持部５との間の間隔を小さくすると、横向き姿勢で停止していた下挟持部５が上フランジ１３ａの下面に当接したままナット１８の当接部分を中心に回動して傾き、第２下挟持部５ｂが床パネル１４の下面に当接する。   When the interval between the upper clamping unit 4 and the lower clamping unit 5 is reduced, first, the first lower clamping unit 5a at one end of the lower clamping unit 5 contacts the lower surface of the upper flange 13a. Further, when the interval between the upper clamping portion 4 and the lower clamping portion 5 is reduced, the lower clamping portion 5 that has been stopped in the lateral orientation is centered on the contact portion of the nut 18 while being in contact with the lower surface of the upper flange 13a. The second lower holding part 5b comes into contact with the lower surface of the floor panel 14.

この第１下挟持部５ａ、第２下挟持部５ｂが、上フランジ１３ａの下面、床パネル１４の下面に当接した状態で、ボルト９を強く締めつけることで、図９に示されるように、上挟持部４が大径孔部２ｂの底面２ｃに圧接され、且つ、第１下挟持部５ａ、第２下挟持部５ｂが、上フランジ１３ａの下面、床パネル１４の下面に圧接される。   As shown in FIG. 9, the first lower clamping portion 5a and the second lower clamping portion 5b are firmly tightened with the bolt 9 in a state where the lower lower clamping portion 5b is in contact with the lower surface of the upper flange 13a and the lower surface of the floor panel 14. The upper clamping part 4 is pressed against the bottom surface 2c of the large-diameter hole 2b, and the first lower clamping part 5a and the second lower clamping part 5b are pressed against the lower surface of the upper flange 13a and the lower surface of the floor panel 14.

このようにして、固定金物１１により固定対象１である梁１３と床パネル１４が上下から挟持されて固定されることになる。   In this way, the beam 13 and the floor panel 14 which are the objects to be fixed 1 are sandwiched and fixed from above and below by the fixed hardware 11.

本実施形態の固定金物１１は、ボルト９に上挟持部４及び下挟持部５を備える構成なので、従来のように金物基体を必要とせず、部材点数を少なくできて、構成が簡略化され、金物コストが安価となる。   Since the fixed hardware 11 of the present embodiment is configured to include the upper clamping portion 4 and the lower clamping portion 5 in the bolt 9, it does not require a hardware base as in the prior art, the number of members can be reduced, and the configuration is simplified. Hardware cost is low.

また、本実施形態は、下挟持部５が横向き姿勢で、シーソ揺動が可能なので、上フランジ１３ａの肉厚が異なる場合であっても、挟持状態における下挟持部５の回動角度が異なるのみで、第１下挟持部５ａ、第２下挟持部５ｂが、上フランジ１３ａの下面、床パネル１４の下面に圧接される。   Further, in the present embodiment, since the lower clamping portion 5 is in the horizontal posture and the seesaw can be swung, even if the thickness of the upper flange 13a is different, the rotation angle of the lower clamping portion 5 in the clamping state is different. Only, the 1st lower clamping part 5a and the 2nd lower clamping part 5b are press-contacted to the lower surface of the upper flange 13a, and the lower surface of the floor panel 14. FIG.

これにより、下挟持部５は両端部の第１下挟持部５ａ、第２下挟持部５ｂが固定対象１である梁１３の上フランジ１３ａと下面と床パネル１４の下面に２箇所で圧接挟持されるので、固定対象１の下面側における固定箇所が増えて強固に固定される。   Thereby, the lower clamping part 5 is press-clamped at two places on the upper flange 13a and the lower surface of the beam 13 and the lower surface of the floor panel 14 where the first lower clamping part 5a and the second lower clamping part 5b at both ends are fixed objects 1. Therefore, the number of fixing points on the lower surface side of the fixing object 1 is increased and the fixing object 1 is firmly fixed.

しかも、固定金物１１に振動が加わっても、下挟持部５は２箇所で圧接して挟持しているので、挟持位置がずれ難く、安定した固定が可能となる。   In addition, even if vibration is applied to the fixed hardware 11, the lower clamping portion 5 is clamped by pressing at two locations, so that the clamping position is not easily displaced and stable fixing is possible.

図１０には他の実施形態が示されている。   FIG. 10 shows another embodiment.

本実施形態の基本的構成は、前述の図１乃至図９に示される構成と同じなので、異なる構成について説明する。   Since the basic configuration of this embodiment is the same as the configuration shown in FIGS. 1 to 9 described above, a different configuration will be described.

上挟持部４を構成する座金部材４ａから細巾板状又は棒状の水平回転規制部２５が下方に向けて突出形成され、この水平回転規制部２５の下端が細長部材１５の側面片１５ａの外面に当接又は小間隙を介して沿わせてある。   A narrow plate-like or bar-like horizontal rotation restricting portion 25 is formed to project downward from a washer member 4 a constituting the upper clamping portion 4, and the lower end of the horizontal rotation restricting portion 25 is the outer surface of the side piece 15 a of the elongated member 15. And abutting or passing along a small gap.

水平回転規制部２５は、座金部材４ａの外端より内側に引き込んだ位置から下方に突出形成される。   The horizontal rotation restricting portion 25 is formed to project downward from a position where it is pulled inward from the outer end of the washer member 4a.

本実施形態では、水平回転規制部２５の下端が細長部材１５の側面片１５ａの外面に当接又は小間隙を介して沿わせてあることで、細長部材１５が座金部材４ａに対して平面視での位置が規定され、座金部材４ａに対して回動ができない構造とされている。   In the present embodiment, the lower end of the horizontal rotation restricting portion 25 is in contact with the outer surface of the side piece 15a of the elongated member 15 via a small gap, so that the elongated member 15 is viewed in plan with respect to the washer member 4a. The position is defined so that it cannot rotate with respect to the washer member 4a.

このため、ボルト９を回転した際、ナット１８がボルト９と共回りして平面視で細長部材１５が回動するのが規制され、第１下挟持部５ａが、平面視で上フランジ１３ａの下面側から外れるのを防止しながら、ボルト９を締め付けることが可能となる。   For this reason, when the bolt 9 is rotated, the nut 18 rotates together with the bolt 9 and the elongated member 15 is restricted from rotating in a plan view, and the first lower clamping portion 5a is connected to the upper flange 13a in a plan view. The bolt 9 can be tightened while preventing it from coming off from the lower surface side.

この場合、図１０のように座金部材４ａに下向き突起４ｃが設けられていると、下向き突起４ｃが大径孔部２ｂの底面２ｃに食い込んで座金部材４ａの平面視における回転をより防止することが可能となる。したがって、下向き突起４ｃを設けた場合は、平面視で細長部材１５が回動するのがよりいっそう規制される。下向き突起４ｃは１個でもよいが、複数設けるのが好ましい。   In this case, when the downward projection 4c is provided on the washer member 4a as shown in FIG. 10, the downward projection 4c bites into the bottom surface 2c of the large-diameter hole portion 2b to further prevent the washer member 4a from rotating in plan view. Is possible. Therefore, when the downward projection 4c is provided, the elongated member 15 is further restricted from rotating in plan view. Although the number of the downward projections 4c may be one, it is preferable to provide a plurality.

もちろん、図１乃至図９の実施形態においても、座金部材４ａに下向き突起４ｃが設けてあってもよい。   Of course, also in the embodiment of FIGS. 1 to 9, the washer member 4a may be provided with a downward projection 4c.

また、座金部材４ａには切欠きが設けてあって、この切欠きにより目印部１６が構成されている。上記のように、細長部材１５が座金部材４ａに対して平面視での位置が規定されているため、目印部１６の向きを床パネル１４の上面側で確認することで、床パネル１４の下面側において、細長部材１５の横向きに倒れる方向を確認することが可能となる。   Further, the washer member 4a is provided with a notch, and the mark portion 16 is constituted by this notch. As described above, the position of the elongated member 15 in a plan view with respect to the washer member 4a is defined. Therefore, by confirming the orientation of the mark portion 16 on the upper surface side of the floor panel 14, the lower surface of the floor panel 14 is obtained. On the side, it is possible to confirm the direction in which the elongated member 15 is tilted sideways.

図１１には更に他の実施形態が示されている。   FIG. 11 shows still another embodiment.

本実施形態の基本的構成は、前述の図１乃至図９に示される構成と同じなので、異なる構成について説明する。   Since the basic configuration of this embodiment is the same as the configuration shown in FIGS. 1 to 9 described above, a different configuration will be described.

上挟持部４を構成する座金部材４ａには、棒材挿入孔４ｄが形成され、この棒材挿入孔４ｄに上方から棒材２６が挿入される。   The washer member 4a that constitutes the upper clamping part 4 is formed with a bar insertion hole 4d, and the bar 26 is inserted into the bar insertion hole 4d from above.

棒材２６は上端部にストッパ２６ａを備えている。この棒材２６は、図８に示される段階で、棒材挿入孔４ｄに上方から挿入され、棒材２６の下端が図１１（ｂ）のように逆ハ字状をした受け部１５ｆ内に嵌め込まれる。   The bar 26 is provided with a stopper 26a at the upper end. At the stage shown in FIG. 8, the bar 26 is inserted into the bar insertion hole 4d from above, and the lower end of the bar 26 is in a receiving portion 15f having an inverted C shape as shown in FIG. 11B. It is inserted.

この状態で、ボルト９を上方から回転操作して横向き姿勢の細長部材１５がナット１８により上方に押し上げられると、棒材２６が上方に持ち上げられ、ストッパ２６ａの座金部材４ａからの上方への突出量が増えていく。これにより、ボルト９の回転操作で細長部材１５が上方に移動していることが床パネル１４の上面側から確認できる。   In this state, when the bolt 9 is rotated from above and the elongated member 15 in the lateral orientation is pushed upward by the nut 18, the bar 26 is lifted upward, and the stopper 26a protrudes upward from the washer member 4a. The amount increases. Thereby, it can confirm from the upper surface side of the floor panel 14 that the elongate member 15 is moving upwards by rotation operation of the volt | bolt 9. FIG.

また、本実施形態においては、棒材２６の下端が逆ハ字状をした受け部１５ｆ内に嵌め込まれることで、ボルト９を回転した際、ナット１８がボルト９と共回りして平面視で細長部材１５が回動するのが規制される。   Further, in the present embodiment, the lower end of the bar 26 is fitted into the receiving portion 15f having an inverted C shape so that when the bolt 9 is rotated, the nut 18 rotates together with the bolt 9 in a plan view. The elongate member 15 is restricted from rotating.

したがって、本実施形態においても、第１下挟持部５ａが、平面視で上フランジ１３ａの下面側から外れるのを防止しながら、ボルト９を締め付けることが可能となる。   Therefore, also in the present embodiment, it is possible to tighten the bolt 9 while preventing the first lower clamping portion 5a from being detached from the lower surface side of the upper flange 13a in plan view.

本実施形態においては、棒材挿入孔４ｄ又は棒材挿入孔４ｄに挿入された棒材２６で目印部１６が構成されている。上記のように、棒材挿入孔４ｄに挿入された棒材２６が受け部１５ｆ内に嵌め込まれるため、目印部１６の向きを床パネル１４の上面側で確認することで、床パネル１４の下面側において、細長部材１５の横向きに倒れる方向を確認することが可能となる。   In the present embodiment, the mark portion 16 is constituted by the bar insertion hole 4d or the bar 26 inserted into the bar insertion hole 4d. As described above, since the bar 26 inserted into the bar insertion hole 4d is fitted into the receiving portion 15f, the orientation of the mark portion 16 is confirmed on the upper surface side of the floor panel 14, and thus the lower surface of the floor panel 14 is confirmed. On the side, it is possible to confirm the direction in which the elongated member 15 is tilted sideways.

ところで、下挟持部５をボルト９に回動自在に取付ける形態は、前述の各実施形態にのみ限定されず、要は、下挟持部５は、垂直面内で回動自在で且つ上下方向に移動可能となり、垂直面内で回動することで、ボルト９に沿うように起立する起立姿勢と、横向きとなる横向き姿勢が可能となるようにボルト９に取付けられるものであればよい。   By the way, the form in which the lower holding part 5 is rotatably attached to the bolt 9 is not limited to the above-described embodiments. In short, the lower holding part 5 is rotatable in the vertical plane and vertically. What is necessary is just to attach to the volt | bolt 9 so that it can move and can stand in the standing posture to stand along the volt | bolt 9 by turning in a vertical surface, and the horizontal stance which becomes sideways.

また、下挟持部５は、前述の実施形態のように、ボルト９に対して長手方向の略中間部分で回動自在に支持されて、起立状態から側方に回動した場合、自由状態で左右のバランスが取れて横向きとなる横向き姿勢となるように構成されたものにのみ限定されない。   Further, as in the above-described embodiment, the lower holding portion 5 is supported rotatably at a substantially intermediate portion in the longitudinal direction with respect to the bolt 9, and in the free state when rotated from the standing state to the side. It is not limited only to what was comprised so that the left-right balance may be taken and it may become a sideways posture which becomes sideways.

つまり、起立姿勢から側方に回動した場合、下支持部５が横向きになると、回動規制手段で回動が規制されてそれ以上回動しないような構造でもよい。   That is, when it rotates to the side from the standing posture, when the lower support portion 5 is turned sideways, the rotation is restricted by the rotation restricting means and may not be rotated any more.

なお、添付図面の実施形態では、固定対象１が梁１３と、この梁１３に載置された床パネル１４の例で説明したが、必ずしもこの例にのみ限定されず、固定対象１が屋根材と屋根下地構造材であってもよく、また、固定対象１として他の種々の建築部材であってもよい。   In the embodiment of the accompanying drawings, the fixing object 1 is described as an example of the beam 13 and the floor panel 14 placed on the beam 13. However, the fixing object 1 is not necessarily limited to this example. The roof base structure material may be used, and the fixing object 1 may be other various building members.
