In the present embodiment, the vertical direction in FIG. 1 will be described as the vertical direction of the device support and the attachment device for wiring devices.

  1 to 3, the device support 11 is used to attach wiring devices such as a sensor and a wiring box to a structure such as a wall surface of a building, a suspension bolt, and a shape steel. A pair of screws 51, 51 are attached to each other. The main body 21 includes a fixing portion 22 fixed to the structure and an attachment portion 23 to which wiring devices are attached. A screw hole 34 and a screw lower hole 35 are provided in the mounting portion 23, and a screw 51 is attached to the screw hole 34. Hereinafter, each component will be described in detail. Here, a case where the sensor 61 is attached as the wiring device will be described.

  The main body 21 is generally formed in an L-shaped plate shape, and the vertical portion constitutes a fixing portion 22 and the horizontal portion constitutes an attachment portion 23. The main body 21 is integrally formed using a synthetic resin material. The fixing portion 22 is formed of a rectangular side wall 24 or the like, and a pair of frame plate portions that are erected at a certain height in a direction orthogonal to the side wall 24 at both left and right end portions on the outer surface side of the side wall 24. 25 and 25 are integrally provided along the end portions, and the inner dimensions of the pair of frame plate portions 25 and 25 are formed substantially the same as the width of the substrate 72 of the suspension bolt support 71 described later. The upper end of the side wall 24 of the fixed portion 22 has a protruding piece 26 standing on the mounting portion 23 side, and a pair of engaging protruding pieces 27 and 27 formed on the left and right sides on the opposite side of the protruding piece 26. The insertion groove 28 into which the intermediate portion in the height direction of the substrate 72 of the suspension bolt support 71 is inserted is formed.

  Further, a fixing hole 29 through which a fixing bolt for fixing to the wall surface of the structure is inserted is provided in the upper part of the side wall 24 of the fixing part 22, and the substrate 72 of the suspension bolt support 71 is formed in the lower part of the side wall 24. An insertion hole 30 is provided through which the protruding blocking pin 76 is inserted.

  On the other hand, the attachment portion 23 is formed in an elongated rectangular shape, and a peripheral wall 32 having a fixed height is provided along the periphery of the bottom plate 31. A cable insertion hole 33 through which a cable from the sensor 61 is inserted is formed in a portion slightly opposite to the fixed portion 22 in the central portion in the length direction of the mounting portion 23. The bottom plate 31 is provided with a screw hole 34 and a screw lower hole 35 on both sides of the cable insertion hole 33. Specifically, as shown in FIG. 1B and FIG. 3, a longitudinal direction with a constant width adjacent to the cable insertion hole 33 on both sides in the longitudinal direction sandwiching the cable insertion hole 33 in the bottom plate 31 of the mounting portion 23. The first elongated hole 35a and the second elongated hole 35b extending in the longitudinal direction are formed, and the first screw hole 34a and the second screw hole 34b having round holes are formed on both sides in the longitudinal direction of the elongated holes. A third elongated hole 35c is formed adjacent to the second screw hole 34b. Screws 51 are attached to the first screw holes 34a and the second screw holes 34b. The first to third long holes are screw pilot holes 35 to which the screws 51 may be attached in the future.

  The pitch P1 between the first screw hole 34a and the second screw hole 34b corresponds to the standard pitch P2 of the pair of screw through holes 64, 64 to which the pair of screws 51, 51 are attached in the sensor 61. Is set to the same size. In addition to the screw hole 34, the screw lower hole 35 is also provided for the sensor 61 in which the pitch P2 of the pair of screw through holes 64, 64 is different from the pitch P2 of the standard sensor 61. This is because the screw 51 can be attached. In addition, when attaching the sensor 61 which has a pair of screw through-holes 64 and 64 of different pitch P2, the screw 51 attached to the screw lower hole 35 of the attachment part 23 of the main body 21 is the apparatus support 11 in advance. The screw 51 may be the same as the screw 51 attached to the device support 11 or may be a different one obtained by replacing the screw 51 attached to the device support 11 in advance.

  Furthermore, each screw hole 34 is provided with a thin partition wall 36 that can be pierced at a substantially intermediate position in the depth direction. Further, on the back side of each screw hole 34, there is formed a portion A that is screwed while being screwed by itself when further tightening the screw 51. Moreover, the 1st-3rd long hole is formed with the vertical wall 37 on both sides, and the space | interval of the inner surface of both the vertical walls 37 is formed in the width | variety which can be attached, screwing the inner surface with the bis | screw 51. . The screw holes 34 and the screw lower holes 35 made of long holes are arranged on the center line C in the width direction of the mounting portion 23. This center line C is also the axial center of the pair of screws 51, 51.

  In the mounting portion 23, the central portion in the width direction of the upper surface of the bottom plate 31 is parallel along the length direction on both sides of the cable insertion hole 33 as shown in FIGS. 1 (a) and 2 (a). A pair of the aforementioned vertical walls 37, 37 are erected, and the upper ends of the pair of vertical walls 37, 37 are closed by the upper wall 38. A portion of the vertical wall 37 on the fixing portion 22 side is gradually raised in the middle, and a bolt through which a mounting bolt 86 for attaching the structural steel fixture 81 to the main body 21 passes in a portion adjacent to the fixing portion 22. A through hole 39 is formed. The bolt through hole 39 constitutes a part of the fixing portion 22. The interval between the outer surfaces of both vertical walls 37 is formed to be the same or slightly larger than the interval between the pair of left and right side walls 24, 24 of the structural steel fixture 81 described later. The vertical wall 37 and the pair of side walls 24 and 24 of the structural steel fixture 81 are fitted.

  A cable holding portion 40 that holds a cable is provided in a portion near the fixing portion 22 in the peripheral wall 32 on both sides of the attachment portion 23. The cable holding portion 40 is provided with a gripping piece 41 along the peripheral wall 32 at a position separated from the peripheral wall 32, and the cable is forcibly pushed from the insertion opening 42 at the end on the fixed portion 22 side to grip the peripheral wall 32. The cable is elastically sandwiched and held by the piece 41.

  Furthermore, as shown in FIGS. 1B and 2, the screw 51 attached to the screw hole 34 has a head 52 protruding downward by a predetermined distance, that is, the surface of the bottom plate 31 on which the screw 51 is attached. A gap L is formed between the lower surface 31a and the head portion 52 of the screw 51, and the gap L is a through hole for a screw of the sensor 61 shown in FIG. 64 and slightly larger than the distance in the height direction between the peripheral edge of the upper opening of the base 63 and allows the enlarged portion 64a of the screw through-hole 64 provided in the base 63 of the sensor 61 to pass through. By rotating the sensor 61 along the arc shape of the long hole 64b, the sensor 61 is formed in a size that can be hooked on the screw 51. In this state, as shown in FIG. 2 (d), the screw 51 is screwed to the middle of the depth direction without breaking through the partition wall 36 in the screw hole 34 at the tip of the shaft portion. The partition wall 36 prevents dust and the like from entering from the outside when the screw 51 is not attached.

  Here, the screw 51 previously attached to the screw hole 34 is a tapping screw, and from the lower surface 31a of the bottom plate 31 that is the attachment surface, the screw 51 that is the back side of the screw hole 34 described above is inserted. Further, the portion between the portion where the screw is advanced while being screwed by itself when tightening may be screwed by screwing and temporarily held until the sensor 61 is attached, or may not be screwed. Alternatively, it may be temporarily held in the screw hole 34 by press fitting or the like.

  For example, as shown in FIGS. 4 (a) and 4 (b), the inner surface of the screw hole 34 on the attachment surface side is slightly smaller than the screw 51 so that threading is started from the above-described location A on the back side of the attachment surface. A semi-cylindrical ridge 34c is provided in the depth direction at equal intervals in the circumferential direction of the inner surface at a large inner diameter, and the projection height gradually increases from the attachment surface toward the rear side. When the tapping screw is pushed into the screw hole 34, the pressure input gradually increases and the tip of the protrusion 34c is crushed. As shown in FIG. 4 (c), the screw 51 is firmly press-fitted and temporarily inserted. You may make it hold | maintain. Alternatively, the screw 51 may be press-fitted in the vicinity of the attachment surface of the screw hole 34, and may be slightly threaded and screwed on the back side in the middle to be temporarily held. If the position of these temporary holding states, that is, the position that will not advance in the screwing direction unless the screw is cut after this is determined as the position where the predetermined gap L is formed, the predetermined gap L can be accurately determined. Can be formed.

Next, a method of attaching the sensor 61 by fixing the device support 11 thus configured to a suspension bolt that is a structure will be described.
The suspension bolt is suspended downward from the ceiling to support various wiring devices, and the suspension bolt shown in FIG. 5 (a) is used to fix the device support 11 of the present embodiment to the suspension bolt. A supporting tool 71 is used. The suspension bolt support 71 is provided with a pair of holding pieces 73 curved in a circular arc shape on one side of a rectangular plate-like substrate 72 and spaced apart by a predetermined distance in the vertical direction. An insertion port 74 into which the suspension bolt 91 can be inserted is formed between the substrate 72. The insertion port 74 of each clamping piece 73 is formed in a direction facing each other. And between the pair of clamping pieces 73, 73 is an insertion portion 75 into which the suspension bolt 91 is inserted.

  With this configuration, the pair of sandwiching pieces 73 and 73 sandwich the suspension bolt 91 from the opposite side so as to be sandwiched between the substrate 72 and the suspension bolt support 71 is fixed to the suspension bolt 91. Here, the board | substrate 72 is formed in the fixed thickness inserted in the insertion groove | channel 28 formed in the right-and-left both sides in the upper end part of the fixing | fixed part 22 of the apparatus support tool 11. FIG.

  On the other side of the substrate 72 of the suspension bolt support 71, an indexing pin 76 protruding in the horizontal direction is integrally provided at the upper and lower ends, and the indexing pin 76 is inserted into the insertion hole 30 of the device support 11. Is inserted. Since the indexing pins 76 are provided on the upper and lower sides of the substrate 72, either one of the suspension bolts 71 is inserted into the insertion hole 30 of the device support 11 without being inverted in any direction. It can be attached to the support 11. Here, a pair of left and right upper ends of the fixing portion 22 of the device support 11 when the substrate 27 is attached to the device support 11 at both ends of the intermediate portion in the height direction of the substrate 72 of the suspension bolt support 71. In order to prevent interference with the engagement protrusions 27, 27, a relief space 77 cut out in a U-shape is formed.

  Therefore, in order to fix the device support 11 to the suspension bolt 91, the suspension bolt support 71 is first attached to the device support 11. For this purpose, the escape space 77 at both ends of the substrate 72 of the suspension bolt support 71 is aligned with the engagement protrusions 27 at the upper end of the fixing portion 22 of the device support 11, and the suspension bolt support 71. The substrate 72 is placed on the side wall 24 of the fixing portion 22 while avoiding interference between the substrate 72 and the engagement protrusion 27 of the device support 11, and moved slightly downward to fix the intermediate portion in the height direction of the substrate 72. While being inserted into the insertion groove 28 of the portion 22, the indexing pin 76 is inserted into the insertion hole 30 of the fixing portion 22 and attached. After being attached in this manner, the suspension bolt support 71 is restricted from moving laterally by the frame plate portions 25 at both left and right end portions of the fixing portion 22 at both end portions. As a result, the suspension bolt support tool 71 simply attaches the substrate 72 to the side wall 24 of the fixing portion 22 and inserts the lower pin 76 into the insertion hole 30 of the fixing portion 22, so that the device support tool 11 can be easily provided. The fixed portion 22 can be attached to a fixed position. A state in which the suspension bolt support 71 is attached to the device support 11 is shown in FIGS.

  When the suspension bolt support 71 is attached to the device support 11, the suspension bolt support 71 mounted in the vertical posture is rotated 90 degrees counterclockwise in the vertical direction together with the device support 11 to the horizontal posture. The suspension bolt 91 is inserted from the insertion portion 75 of the suspension bolt support 71 so as to be applied to the suspension bolt 91 from the side in this posture. If the suspension bolt support 71 is forcibly rotated 90 degrees clockwise in the vertical direction against the elastic force of the pair of holding pieces 73, 73 to return to the original vertical posture, the suspension bolt 91 is obtained. Is sandwiched between the substrate 72 and the sandwiching piece 73 so as to be held inside from the opposite side while being inserted from the insertion ports 74, 74 of the pair of sandwiching pieces 73, 73. As shown in FIG. 6, it is attached to the suspension bolt 91 via a suspension bolt support 71.

  When the device support 11 is fixed to the suspension bolt 91 in this way, the sensor 61 is attached to the mounting portion 23 of the device support 11. The sensor 61 is formed by assembling two divided bodies of a sensor main body 62 and a base 63 in two upper and lower stages. First, the base 63 is attached to the attachment portion 23 of the device support 11, and then the sensor main body 62. Is assembled to the base 63. The base 63 is provided with a pair of screw through holes 64 through which the pair of screws 51 of the device support 11 are inserted.

  In order to attach the sensor 61 to the device support 11, the head 52 of the screw 51 of the device support 11 is in a state of protruding downward from the lower surface 31 a of the bottom plate 31 of the mounting portion 23 by a predetermined distance. ), The base 63 of the sensor 61 is attached from below to the mounting portion 23 while passing the pair of screws 51, 51 through the enlarged portions 64a, 64a of the pair of screw through holes 64, 64 of the sensor 61. Accordingly, it is positioned in the gap L between the lower surface 31 a of the bottom plate 31 and the head 52 of the screw 51. Here, since the gap L is formed slightly larger than the thickness of the sensor 61, the head 52 of the screw 51 is passed through the enlarged portion 64 a of the screw hole 64 of the sensor 61 and the screw hole 64. The sensor 61 can be hooked on the pair of screws 51, 51 of the device support 11 by rotating the arc along the arc of the long hole 64b.

  Thereafter, the screw 51 is screwed and screwed by itself so as to narrow the gap L at the back side of the screw hole 34, and is tightened between the bottom plate 31 of the mounting portion 23 and the head 52 of the screw 51. Attach the base 63 of the sensor 61. Next, when the sensor main body 62 is assembled to the base 63, the attachment of the sensor 61 to the attachment portion 23 of the device support 11 is completed as shown in FIG. Thus, the sensor 61 can be attached to the suspension bolt 91 via the device support 11. Thus, what attached the sensor 61 to the apparatus support 11 comprises the attachment apparatus 1 of wiring apparatuses.

  When the sensor 61 having a pitch P2 between the pair of screw through holes 64, 64 of the base 63 different from the pitch P2 of the sensor 61 is attached to the device support 11, the screw hole 34 and the screw lower hole 35 are mounted. A hole that matches the pitch P2 of the pair of screw through holes 64, 64 is selected, and the pair of screws 51, 51 are attached thereto. In this case, a hole in which the screw 51 is attached may be selected so that the attachment position of the pair of screws 51, 51 is symmetrical with respect to the cable insertion hole 33. Of these, the first screw hole 34a or the second screw hole 34b can be used as it is without changing the attachment position of one screw 51, and only the attachment position of the other screw 51 can be changed.

  In the above description, the sensor 61 is attached after the device support 11 is fixed to the suspension bolt 91, but the sensor 61 is first attached to the device support 11 to which the suspension bolt support 71 is attached. Then, it can be fixed to the suspension bolt 91.

  Alternatively, the sensor 61 is attached to the attachment portion 23 of the equipment support 11 and the suspension bolt support 71 is attached to the suspension bolt 91, and then the index pin 76 of the suspension bolt support 11 is attached to the equipment support 11. The suspension bolt support 11 may be attached to the equipment support 11 by being inserted into the insertion hole 30 of the fixing portion 22. In this case, since the suspension bolt support 71 of the fixing portion 22 of the device support 11 for fixing to the suspension bolt 91 is configured separately from the mounting portion 23 of the device support 11, the sensor 61 is provided. The attachment work is performed at a place where it can be easily attached to the device support 11, and the suspension bolt support 71 that can be fixed independently of the device support 11 is first fixed to the suspension bolt 91, and then the device support 11 is attached thereto. Therefore, the mounting operation can be performed efficiently even in a narrow space.

  In this case, the operation of fixing the suspension bolt support 71 to the suspension bolt 91 is a rotation operation of fixing the suspension bolt support 71 to the suspension bolt 91 while rotating the suspension bolt support 71. 11 is attached to the suspension bolt support tool 71 by a linear operation for fitting the insertion hole 30 of the fixing portion 22 toward the suspension bolt 91 toward the retaining pin 76 of the suspension bolt support tool 71. By operating in a direction different from the direction in which the bolt support 71 is removed from the suspension bolt 91, the device support 11 can be attached to and integrated with the suspension bolt support 71.

  However, the device support 11 of the present invention is attached to the device support 11 after that in a state where the device support 11 is fixed in advance to a structure such as a hanging bolt 91 or a steel plate 92 at a high place. This is particularly effective when it is attached to a structure such as the suspension bolt 91 via the device support 11.

  By the way, although the case where the apparatus support 11 was fixed to the suspension bolt 91 which is a structure was demonstrated above, the apparatus support 11 can also be directly fixed to the wall surface which is a structure using a fixing bolt. . In that case, the fixing bolt can be inserted into the fixing hole 29 of the fixing portion 22 of the device support 11 and fixed to the wall surface.

  Moreover, the apparatus support tool 11 can also be fixed to the structural steel as a structure. In order to fix the equipment support 11 to the structural steel, a structural steel fixing tool 81 shown in FIG. 8A is used. The steel plate fixture 81 is formed by bending a metal plate material, and a pair of left and right side-view substantially U-shaped side plates 82 facing each other at a predetermined interval. The notch portion forms an insertion space 83 into which the flange 93 of the shape steel 92 is inserted. Further, a pair of sandwiching pieces 84 which are bent at a right angle and project outward in the horizontal direction are formed on the left and right edges of the insertion space 83. The distance between the pair of left and right side plates 82, 82 is formed to be the same as or slightly smaller than the outer dimension between the two vertical walls 37, 37 of the device support 11, and supports the structural steel fixture 81.
