The fixing tool 11 and an attracting tool 31 that pulls the fixing tool 11 toward the flange portion 62 are configured.

Hereinafter, each component will be described in detail.
The suspension bolt 51 is suspended from the fixture 11 by sandwiching a connecting wall 13 of the fixture 11 described later with a pair of upper and lower nuts 52 screwed into the suspension bolt 51.

  As shown in FIGS. 5 and 6, the fixture 11 is formed by bending a metal plate material such as a steel plate by pressing, and has a pair of opposing side walls 12, 12 and a connecting wall 13 that connects both side walls 12. Have. The connecting wall 13 is formed as an upper top wall and a lower bottom wall in FIG. Both side walls 12 have an opening 14 into which a flange portion 62 of a shaped steel material 61 is inserted by being cut out in a substantially U shape. A pair of abutting flanges 16 are formed on the opening edge 15, which is the lower edge of the opening 14 of the side wall 12, and are bent outward from each other perpendicular to the side wall 12. Is configured such that the lower surface of the flange portion 62 of the shaped steel material 61 comes into surface contact.

  At the center position in the width direction on the opening 14 side where the flange portion 62 of the upper connecting wall 13a that is the top wall is inserted, the flange portion 62 of the structural steel member 61 is moved up and down with the contact flange 16 of the opening edge 15 of the side wall 12. A screwing hole 17 is provided in which a holding bolt 53 for holding from the direction is screwed. Accordingly, the flange portion 62 of the structural steel member 61 inserted from the opening 14 is sandwiched between the contact flange 16 of the opening edge 15 of the fixture 11 and the tip of the clamping bolt 53, and the fixture 11 is the flange portion of the structural steel material 61. 62 is fixed. As the clamping bolt 53, a hexagonal bolt is used, and the tip of the threaded portion is formed in a flat surface so as to stably contact the surface of the flange portion 62 of the shaped steel material 61.

  In addition, a through hole 20 is provided on the back side 18 behind the screw hole 17 in the upper connecting wall 13a, that is, on the side opposite to the opening 14 of the side wall 12, and the upper side through the upper connecting wall 13b. A similar through hole 20 is provided at a position facing the hole 20. These through holes 20 are a feature of the present invention, and the suspension bolt 51 is inserted through the upper through hole 20 and the lower through hole 20 in the vertical direction, that is, in a direction orthogonal to the direction of the openings 14 of the side walls 12. It is like that. Here, the opening direction of the both side walls 12 is a direction parallel to the flange portion 62 of the shaped steel material 61. These through-holes 20 are located between the center position between both side walls 12 in the state where the suspension bolt 51 is inserted, that is, the center position in the width direction of the connecting wall 13 and the position shifted from the center to the one side wall 12 side. It is formed in the shape of a long hole that can be moved. Thus, the suspension bolt 51 can be inserted into the through hole 20 by selecting either the center position between the side walls 12 of the fixture 11 or a position shifted from the center. The position shifted from the center between the both side walls 12 is a position where the inner surface of one side wall 12 on the shifted side substantially contacts the edge of the through hole 20 on the shifted side. Here, the term “substantially contact” means that the inner surface of one side wall 12 on the shifted side and the edge of the through hole 20 on the shifted side coincide or close to each other.

  The size L between the side walls 12 of the fixture 11 is such that when the suspension bolt 51 is inserted into the center position between the side walls 12 of the through hole 20, the size L is between the both sides of the outer surface of the suspension bolt 51 and the side walls 12.

The nuts 52 for fixing the suspension bolts 51 sandwich the connection walls 13 from above and below in each of the upper connection wall 13a and the lower connection wall 13b. That is, a total of four suspension bolts 51 are used. May be fixed. Alternatively, the nut 52 is not attached to the through hole 20 of the lower connecting wall 13b, but is simply inserted, and the nut 52 is attached to both the upper and lower sides of the through hole 20 of the upper connecting wall 13a, and the upper connecting wall 13a is moved up and down. It is good also as what fixes the suspension bolt 51 by pinching from.

  Furthermore, at the end portions 19 on the back side 18 of both side walls 12 of the fixture 11, an elongated hole-shaped locking hole 21 that locks one wall portion 41 of a locking body 34 of the attracting tool 31 described later. Is provided.

  Next, the attracting tool 31 is sandwiched between the sandwiching body 32 fixed to the flange 62 on the opposite side of the fixing tool 11 in the shaped steel material 61 and the both side walls 12 of the fixing tool 11 having one end fixed to the flange 62. A rod-shaped portion 33 that is inserted along the flange portion 62 and connects the fixture 11 and the sandwiching body 32, and is locked to the end portion of one side wall 12 of the fixture 11 to fix the fixture 11 and the rod-shaped portion 33. It is comprised with the latching body 34 to connect.

  Among these, first, the clamping body 32 clamps the structural steel material 61 in the width direction of the flange portion 62 of the structural steel material 61, that is, the extending direction of the flange portion 62 together with the locking body 34 of the attracting tool 31. As shown in FIG. 7, a symmetrical steel plate is folded back 180 degrees in the center to form a substantially U-shaped cross section, and a pair of side plates 35 are opposed to each other with a gap therebetween. The both side plates 35 are formed with a notch space 36 having an insertion opening at a side end facing the side edge of the flange portion 62 of the shaped steel material 61, and the flange portion 62 of the shaped steel material 61 is formed at the back of the notched space 36. The end edge part comes into contact. The folded portion 37 at the center of the sandwiching body 32 is formed to have an inner diameter slightly larger than the outer diameter of the rod-shaped portion 33, and the rod-shaped portion 33 can be inserted into the folded portion 37. Further, the both side plates 35 are provided with recesses 38 having a predetermined length that are recessed inwardly to increase the rigidity of the side plates 35, and the recesses of the recesses 38 come into contact with the outer surface of the rod-shaped portion 33, thereby The portion 33 is prevented from coming off the folded portion 37 after being inserted into the folded portion 37 of the holding body 32.

  Next, the rod-shaped portion 33 is formed of a straight bolt body having a thread formed on the outer surface at a part of the entire length, or the entire length thereof is at least long enough to connect the fixture 11 and the holding body 32. It is formed and disposed on the lower surface side of the flange portion 62 of the shaped steel member 61. A nut 39 and a washer 40 are attached to the end of the rod-shaped portion 33 on the side of the sandwiching body 32. In addition, the rod-shaped part 33 may provide a thread part only in both ends.

  The locking body 34 is attached to the end portion of the one side wall 12 of the fixture 11 and, as shown in FIG. 7, a pair of opposing members folded back at an intermediate portion by bending a flat plate made of steel. The whole is formed in a substantially U-shaped plate shape or a substantially U-shaped plate shape. One opposing wall portion 41 of the locking body 34 is locked in a locking hole 21 provided at the end of one side wall 12 of the fixture 11 and slightly in the center portion than the outer diameter of the rod-shaped portion 33. A through hole 42 having a large inner diameter is provided. The opposing wall 43 is provided with a screwing hole 44 that is screwed with the threaded portion of the rod 33 on the same position as the through hole 42 of the one wall 41, that is, coaxially with the through hole 42. Yes.

  The locking body 34 is provided at the end portion 19 on the rear side 18 of the side wall 12 of the fixture 11, with one wall portion 41 exceeding the axis of the clamping bolt 53 in the width direction of the flange portion 62 of the shaped steel member 61. The through hole 42 formed in the one wall portion 41 in a state where the other wall portion 43 is disposed on the back side 18 of the side wall 12 of the fixture 11, that is, on the outside of the opposite opening side. The one end side of the rod-shaped portion 33 penetrates, and the screw portion formed on the one end side of the rod-shaped portion 33 is screwed into the screwing hole 44 formed in the other wall portion 43, so that the fixing tool 11 is engaged. It has come to be stopped.

Next, a method for attaching and suspending the suspension bolt 51 to the shaped steel member 61 using the fixture device 1 configured as described above will be described.
First, the left flange portion 62 of the shaped steel member 61 is inserted from the opening 14 of the side wall 12 of the fixture 11, and the tip of the flange portion 62 is brought into contact with the inner portion of the opening 14 of the fixture 11. Then, the clamping bolt 53 is tightened to clamp the flange portion 62 of the shaped steel member 61 with the contact flange 16 of the opening edge 15 of the side wall 12 of the fixture 11. As a result, the fixture 11 is fixed to the flange portion 62 of the shaped steel member 61.

  Subsequently, the suspension bolt 51 is inserted into the through holes 20 of the upper and lower connecting walls 13 of the fixture 11. At this time, the suspension bolt 51 is inserted through the through hole 20 formed of a long hole in the connecting wall 13 at a position shifted from the center between the side walls 12 toward the side wall 12. As a result, the suspension bolt 51 is brought closer to the one side wall 12 between the side walls 12, and the space between the outer surface of the suspension bolt 51 and the inner surface of the other side wall 12 is increased by the amount of the suspension bolt 51 being approached. Therefore, the rod-shaped portion 33 of the attracting tool 31 can be inserted between the outer surface of the suspension bolt 51 and the inner surface of the other side wall 12.

  On the other hand, the attracting tool 31 has the rod-shaped portion 33 inserted through the folded-back portion 37, and a washer 40 and a nut 39 are attached to the end of the rod-shaped portion 33. In this state, next, one wall 41 of the locking body 34 of the attracting tool 31 is inserted into and engaged with the locking hole 21 at the end of the side wall 12 of the fixture 11, and the other wall 43. Is disposed on the back side 18 of the side wall 12, that is, outside the non-opening side. Next, the holding body 32 of the attracting tool 31 is disposed on the right flange portion 62 side of the shaped steel member 61, and the end portion of the rod-like portion 33 opposite to the holding body 32 is arranged on the one wall portion 41 of the locking body 34. It is inserted into the through hole 42 and further screwed into the screw hole 44 of the other wall portion 43. Subsequently, while the right flange portion 62 of the shaped steel member 61 is inserted into the notch space 36 of the clamping body 32 of the attracting tool 31, the clamping body 32 is moved to the locking body 34 side, and the nut 39 is tightened to clamp the clamping body. 32 is fixed to the flange 62 on the right side of the shaped steel member 61. Thereby, the flange part 62 of the shaped steel material 61 is clamped by the fixture 11 and the clamping body 32. The state in which the fixture 11 is attached to the shaped steel material 61 is shown in FIGS.

As described above, the suspension bolts 51 are fixed to the structural steel member 61 and suspended while the attracting tool 31 is attached.
In the above, the attracting tool 31 is attached after the fixing tool 11 is first fixed to the flange portion 62. However, if there is a margin in the length of the rod-shaped portion 33, the fixing tool 11 and the attracting tool 31 Can be attached and fixed to the flange portion 62 after being temporarily assembled.

  Next, when the suspension bolt 51 is suspended from the structural steel member 61 without attaching the attracting tool 31, the suspension bolt 51 is inserted through the connecting wall 13 of the fixture 11 at the center position between the side walls 12. This is because if the suspension bolt 51 is inserted at the center position, the suspension bolt 51 can be suspended in a stable state with a good left-right balance.

Next, the operation of the fixture 11 and the fixture device 1 of the first embodiment will be described.
The fixture 11 of the first embodiment has a size L between the side walls 12 when the suspension bolt 51 is inserted into the center position between the side walls 12 of the through hole 20 so as to be compact as described later. The rod-shaped part 33 of the attracting tool 31 is formed in a small width between the both sides of the outer surface of the suspension bolt 51 and the both side walls 12. In the fixture 11 having such a structure, the through-hole 20 provided in the connecting wall 13 is provided in the center position between the side walls 12 and a position shifted from the center in the form of a long hole. Thus, by inserting and hanging the suspension bolt 51 at a position shifted from the center, the space between the side wall 12 on the opposite side to the shifted side and the suspension bolt 51 is expanded, and the drawing perpendicular to the suspension bolt 51 is drawn. The bar-shaped portion 33 of the tool 31 can be inserted into the space. As a result, the lifting tool 31 can be attached even when the suspension bolt 51 is suspended from the upper connecting wall 13a and vertically inserted into the fixing tool 11, so that the fixing tool 11 is more firmly shaped. It can be fixed to the flange portion 62 of the steel material 61. Further, when the attracting tool 31 is not used, the suspension bolt 51 can be inserted at the center position between the side walls 12 and suspended in a balanced state.

  The suspension bolt 51 and the rod-shaped portion 33 of the attracting tool 31 are substantially in contact with each other between the both side walls 12 of the fixing tool 11, and the outer surface of the suspension bolt 51 and the rod-shaped portion 33 of the attracting tool 31 are disposed. Since the outer surfaces of the two side walls 12 are formed so as to be in contact with the inner surfaces of the adjacent side walls 12, the size L between the side walls 12 can be minimized. As a result, since the fixture 11 can be reduced in size, storage space and transportation space can be reduced, and handling becomes easy. In addition, the suspension bolt 51, the rod-shaped portion 33 of the attracting tool 31 and each side wall 12 are in contact with each other, that is, there is no gap between them. It is stably held at a fixed position without being displaced or rattling.

  Furthermore, since the through hole 20 of the connecting wall 13 is formed in a long hole shape, the suspension bolt 51 can be moved between the center position and the position shifted from the center in the long hole by simply loosening the nut 52. It is possible to save the trouble of removing the nut 52 every time the suspension position is changed.

  In addition, one end side of the attracting tool 31 is fixed in a state in which the end of the side wall 12 of the fixing tool 11 is surrounded in a ring shape by a U-shaped or U-shaped locking body 34 and a rod-shaped portion 33. Since it is locked to the side wall 12 of the tool 11, one end side of the attracting tool 31 is securely attached to the fixing tool 11.

  In addition, the rod-shaped part 33 of the attracting tool 31 can use another bolt body having the same diameter as the suspension bolt 51. In this case, the other bolt body can be used as the rod-shaped portion 33 of the attracting tool 31 by cutting the bolt body such as the suspension bolt 51 remaining at the work site into a predetermined length.

  By the way, in the said embodiment, although the rod-shaped part 33 of the attracting tool 31 is inserted between the both side walls 12 which are the inside of the fixing tool 11, the rod-shaped part 33 of the attracting tool 31 is either one of the fixing tools 11. It is also conceivable to arrange and install it outside the side wall 12. If it is arranged outside the side wall 12 of the fixture 11, the suspension bolt 51 and the rod-shaped portion 33 of the attracting tool 31 do not interfere with each other. This is because it can be inserted and hung.

  However, when the rod-like portion 33 of the attracting tool 31 is disposed outside the side wall 12 of one of the fixtures 11 and attached, the nut 39 of the sandwiching body 32 is tightened to attach the fixture 11 to the flange portion 62 of the structural steel member 61. When pulled to the side, the end on the back side 18 of one side wall 12 of the fixture 11 to which the locking body 34 of the drawing tool 31 is locked is strongly pulled toward the inside of the flange portion 62. . For this reason, in the fixture 11 fixed to the flange portion 62 in the direction orthogonal to the longitudinal direction of the shaped steel material 61, the locking portion of the one side wall 12 with the locking body 34 is the clamping bolt 53 in plan view. And the opening edge 15 as a center, it may rotate in the longitudinal direction of the shaped steel member 61 along the plane of the flange portion 62 and turn diagonally. Depending on the position of the clamping part, the planar shape of the flange part 62, and the like, the flange part 62 may be pulled out. For this reason, the rod-like portion 33 of the attracting tool 31 needs to be inserted between the side walls 12 that are the inside of the fixture 11.

  Moreover, in the said embodiment, the latching body 34 of the drawing tool 31 is the width | variety direction of the flange part 62 of the shaped steel material 61, and the back side 18 of the side wall 12 of the fixing tool 11 beyond the axis | shaft of the clamping bolt 53 is used. The end portion 19 is provided with a locking hole 21 and locked thereto. The locking hole 21 is provided on the opening 14 side of the side wall 12 that is the front side of the clamping bolt 53, that is, the flange portion 62 is inserted. It is also conceivable to lock. If the locking body 34 is to be locked at this position of the fixture 11, the rod-shaped portion 33 of the attracting tool 31 is positioned beyond the axis of the clamping bolt 53, that is, the clamping point between the clamping bolt 53 and the opening edge 15. Since it does not extend to the suspension bolt 51 suspended on the rear side 18 and does not intersect with the suspension bolt 51 and does not interfere with it, the suspension bolt 51 can be attached to the center position between the side walls 12. Because it becomes.

  However, in this case, the fixing tool 11 is strong toward the back side of the flange portion 62 on the front side of the shaft of the holding bolt 53, that is, on the opening 14 side of the side wall 12 from the holding point of the holding bolt 53 and the opening edge 15. Since it is attracted, it tries to rotate downward with the locking portion of the locking body 34 as the center of rotation in a side view. For this reason, the fixture 11 may be detached from the flange portion 62 depending on the position of the clamping point of the fixture 11 in the flange portion 62, the planar shape of the flange portion 62, or the like. For this reason, the locking body 34 of the attracting tool 31 is locked to the end 19 on the back side 18 of the side wall 12 of the fixing tool 11, and at least the clamping bolt 53 that is the clamping point. It is desirable that the shaft is locked to the side wall 12 of the fixture 11 at a position beyond the center position of the screw hole 17 to the back side 18.

<Second embodiment>
Next, a fixture and a fixture device according to the second embodiment will be described with reference to FIGS.
In the fixture 11 of the second embodiment, the suspension bolt 51 is suspended and fixed only to the top wall which is the upper connecting wall 13a. Accordingly, when the fixing device 11 is fixed to the flange portion 62 with the mounting direction turned upside down from that of the first embodiment, the suspension bolt 51 is turned upside down so that the connecting wall 13 is positioned on the lower side. It will be suspended by being fixed to, and will not penetrate vertically through the fixture 11.

Hereinafter, the fixture 11 and the fixture device 1 of the second embodiment will be specifically described focusing on differences from the first embodiment.
The connecting wall 13 of the fixture 11 is provided only on the upper top wall, and one through hole 20 through which the suspension bolt 51 passes is provided at the center position between the side walls 12 of the connecting wall 13. .

  Further, the connecting wall 13 of the top wall is provided with a screw hole 17 into which the clamping bolt 53 is inserted and screwed in a direction perpendicular to the direction of the opening 14 of the both side walls 12. A plurality of clamping bolts 53 are provided so as to be able to be selected and screwed to either the center position between the side walls 12 or a position shifted from the center. Specifically, as shown in FIG. 10, a total of five screw holes 17 are arranged at predetermined intervals on two intersecting diagonal lines, that is, one at the center position. A total of four are provided at positions shifted from the center with the screw hole 17 at the center interposed therebetween.

  The size L between the side walls 12 of the fixing tool 11 is such that the fixing tool 11 is turned upside down, that is, the connecting wall 13 is positioned below the flange portion 62 of the shaped steel member 61 as shown in FIG. When the clamping bolt 53 is screwed at the center position between the both side walls 12 while being fixed to the portion 62, the rod-shaped portion 33 of the attracting tool 31 is interposed between the both sides of the outer surface of the clamping bolt 53 and the both side walls 12. It is formed in a small width that cannot be inserted. In addition, the size L between the both side walls 12 of the fixture 11 is such that the clamping bolt 53 is screwed at a position shifted to the one side wall 12 side from the center between the both side walls 12 of the screw hole 17. The clamping bolt 53 and the rod-shaped portion 33 of the attracting tool 31 are substantially in contact with each other at right angles to each other, and the outer surface of the clamping bolt 53 and the outer surface of the rod-shaped portion 33 of the attracting tool 31 are each substantially adjacent to the inner surface of the adjacent side wall 12. The width is in contact.

  The locking holes 21 of the side wall 12 are formed to be longer in the height direction of the side wall 12 or to be provided at two upper and lower positions in the height direction so as to cope with the case where the fixture 11 is installed upside down. Yes.

  In the fixture 11 of the second embodiment, when the connecting wall 13 of the fixture 11 is located on the upper side and is fixed to the flange portion 62 of the shaped steel member 61, the clamping bolts 53 are arranged on both side walls 12 from the point of balance. Screwed at the center position between. Moreover, the suspension bolt 51 is attached to the center position between the both side walls 12 in the upper connection wall 13a, and is suspended in a state of vertically passing through the fixture 11. In this case, the attracting tool 31 cannot be attached. As described above, the space between the side walls 12 of the fixture 11 is small, and when the suspension bolt 51 is suspended at the center position between the both side walls 12 of the upper connecting wall 13a, the suspension bolt 51 is attracted. This is because the bar-shaped portion 33 of the tool 31 interferes.

  On the other hand, as shown in FIG. 9, when the fixing tool 11 is turned upside down and the connecting wall 13 of the top wall is fixed to the flange portion 62 in a state where the fixing wall 11 is positioned on the lower side, the suspension bolt 51 is positioned on the lower side. The clamping bolt 53 is screwed into a screw hole 17 provided at a position shifted from the center between both side walls 12 of the connecting wall 13. In this case, since the clamping bolt 53 is screwed at a position shifted from the center between the both side walls 12, the gap between the inner surface of the side wall 12 opposite to the shifted side and the outer surface of the clamping bolt 53 increases. The rod-like portion 33 of the drawing tool 31 is inserted into this gap, and one end thereof is attached to the side wall 12 of the fixture 11. Since the suspension bolt 51 is attached to and suspended from the connecting wall 13 located on the lower side, even if the attracting tool 31 is attached, it does not interfere with the rod-shaped portion 33.

  The fixing device 11 and the fixing device 1 of the second embodiment configured as described above operate similarly to the fixing device 11 and the fixing device 1 of the first embodiment, and are screw holes provided in the connecting wall 13. 17 is provided at a position that is offset from the center and between the side walls 12, and by screwing the clamping bolt 53 at a position that is offset from the center of the connecting wall 13, the width between the side walls 12 is small. The clamping bolt 53 and the rod-shaped portion 33 of the attracting tool 31 can be inserted into the fixing tool 11 in a state of being orthogonal to each other. As a result, the fixture 11 can be reduced in size, and the holding bolt 53 and the like can be stably held at a fixed position without being displaced or rattling. Further, when the attracting tool 31 is not used, the clamping bolt 53 is screwed at the center position between the both side walls 12 and the flange portion 62 of the structural steel member 61 is clamped with the opening edge 15 of the side wall 12 in a stable state. be able to.

  In addition, the rod-shaped part 33 of the attracting tool 31 can use another bolt body having the same diameter as the holding bolt 53. In that case, another bolt body can be used as the rod-shaped portion 33 of the attracting tool 31 using a bolt body such as the holding bolt 53 remaining in the work site.
