  The fixing device described in Patent Document 1 makes it possible to adjust the position of the sprinkler head by rotating the screw mechanism. The amount of movement of the position of the sprinkler head depends on the pitch of the long bolt and the length of the long bolt in the screw mechanism. It depends on the number of revolutions.

  Usually, since the pitch of the long bolt is about 1 mm, for example, in order to move the sprinkler head by 10 mm, the long bolt must be rotated 10 times. In such a configuration, the position of the sprinkler head can be finely adjusted. However, when the position of the sprinkler head needs to be greatly changed, a large number of long bolts must be rotated, and the work becomes complicated.

  Further, when the sprinkler head is largely pulled out of the ceiling board for inspection, repair, or the like, the configuration as in Patent Document 1 cannot cope with the movement amount of the sprinkler head is limited. In such a case, it is necessary to open the ceiling board and an operator removes the sprinkler pipe from the slide frame behind the ceiling.

FIG.

  At this time, even if a force is applied to the tube fixture 1 from the outside for some reason, in the tube fixture 1 of the present embodiment, the support holder 10 can be easily detached from the square pipe 4. Absent. For example, when a force is applied to the tube fixture 1 from below in the state of FIG. 5D, the tube fixture 1 is connected to the square pipe 4 by the first lower contact portion 15 and the second lower contact portion 26. It is prevented from coming off.

  5D, when a force is applied from the left side in the X direction of the tube fixture 1, the tube fixture 1 is moved by the first X direction contact portion 14 and the second X direction contact portion 24. It is prevented from coming off from the square pipe 4. Further, due to the structure of the column holding part 10, the tube fixing tool 1 is not detached from the square pipe 4 even if a force is applied from above and on the right side of the tube fixing tool 1.

  Thus, according to the tube fixing tool 1 of the present embodiment, since the first opening 12 and the second opening 22 of the column holding unit 10 have the above-described configuration, the square pipe 4 is fixed by the fixing clip 31. Even before fixing, the square pipe 4 is not easily detached.

FIG. 6A shows a state where the tube fixing tool 1 in the state of FIG. 5D is viewed from the opposite side. In the state of FIG. 6 (A), the fixing clip 31 is lowered below the tubular body fixture 1, but the fixing clip 31 is viewed from the Z direction in the state of FIG. 6 (A). Since it is sometimes formed in a square U shape, it does not interfere with the sprinkler pipe 3 even when it is lowered downward. Further, a stopper 29 for the fixing clip 31 is provided at the lower end of the second holding portion 21 on the fixed side, and positioning can be performed when the fixing clip 31 is lowered.

  From this state, as shown in FIGS. 5E and 6B, the fixed clip 31 is swung so that the engaging portion 34 of the fixed clip 31 is moved to the first engaging groove 18 and the second engaging groove. 28 is engaged. Through the above procedure, the column holding part 10 of the tubular body fixture 1 is attached to the square pipe 4 as a column. The tube fixture 1 of this embodiment can mount the support | pillar holding | maintenance part 10 to the square pipe 4 with the above procedure.

  Next, with reference to FIG. 1 and FIG. 7, a procedure for positioning and fixing the sprinkler pipe 3 with respect to the square pipe 4 by the pipe body holding part 40 in the pipe body fixture 1 of the present embodiment will be described. . First, referring to FIG. 1, the sprinkler pipe 3 is held so that the position of the sprinkler head 2 is a predetermined fixed position from the sprinkler opening 7 provided in the ceiling panel 6 toward the room. The long bolt 41 is rotated in the tightening direction to advance.

  The long bolt 41 can be moved forward and backward by the action of the male screw portion 41 a provided on the surface and the female screw portion 53 provided on the tube body holding portion 40 by rotating in the traveling direction or the backward direction. As shown in FIG. 7A, when the long bolt 41 is rotated in the tightening direction, the long bolt 41 moves in the direction of the arrow 61 in FIG. 7A, and the tip of the long bolt 41 is the tube. The first protrusion 48 of the body contact member 42 is pressed and pushed upward.

  When the first protrusion 48 of the tube contact member 42 is pushed upward in FIG. 7A, the tube contact member 42 swings about the swing shaft 45 and moves in the direction of the arrow 62. The tip of the second protrusion 49 abuts against the sprinkler pipe 3 side. Since the cover 5 is provided on the surface of the sprinkler pipe 3, the second protrusion 49 presses the sprinkler pipe 3 against the square pipe 4 through the cover 5. Since the square pipe 4 is held by the support holder 10, the sprinkler pipe 3 is pressed against the square pipe 4 so that both are positioned and fixed.

  At this time, the second projecting portion 49 of the tube contact member 42 is provided in the axial direction (Z direction) of the sprinkler pipe 3 by the outer member 43 and the inner member 44, so the sprinkler pipe 3 It is possible to prevent the inclination in the axial direction. Further, as shown in FIGS. 7A and 7B, the second protrusion 49 positions the outer member 43 and the inner member 44 in accordance with the thickness of the square pipe 4 (the height in the Z direction). Thus, the inclination of the sprinkler pipe 3 can be effectively prevented, and the pressing force of the sprinkler pipe 3 against the square pipe 4 can be reliably applied.

  Next, a procedure for changing the positions of the sprinkler pipe 3 and the sprinkler head 2 that are once positioned and fixed at predetermined positions will be described. As shown in FIG. 8, the long bolt 41 is provided at a position where a tool such as a screwdriver 8 can be inserted and driven from a gap between the sprinkler opening 7 provided on the ceiling panel 6 and the sprinkler head 2.

  In the state shown in FIG. 7B, when the long bolt 41 is rotated in the backward direction (relaxing direction) as indicated by an arrow 63, the long bolt 41 moves downward as shown in FIG. The pressing of the long bolt 41 to the first protrusion 48 of the body contact member 42 is released. As a result, the second projecting portion 49 is separated from the surface of the sprinkler pipe 3, the pressing of the second projecting portion 49 against the sprinkler pipe 3 is also released, and the tube contact member 42 is moved to the arrow shown in FIG. The sprinkler pipe 3 can be opened by swinging in the direction indicated by 64.

  As described above, when the positioning and fixing to the sprinkler pipe 3 by the tube contact member 42 is released, the sprinkler pipe 3 is movable with respect to the square pipe 4. Therefore, it is suitable, for example, when it is desired to change the protrusion amount of the sprinkler head 2 from the ceiling panel 6 or when the sprinkler head 2 is to be pulled out from the ceiling panel 6 for inspection of the sprinkler head 2.

  Thereafter, when positioning the sprinkler head 2 again, the long bolt 41 is driven and tightened by the driver 8 with the driver 8 as shown in FIG. 8 with the sprinkler head 2 held at an arbitrary position with respect to the ceiling panel 6. Rotate in the direction of Thereby, the first projecting portion 48 of the tube contact member 42 is pushed upward at the tip of the long bolt 41, the parallel portion 47 is swung, and the second projecting portion 49 is moved to the sprinkler pipe 3 side, The square pipe 4 and the sprinkler pipe 3 can be positioned and fixed.

  Thus, according to the tube fixing tool 1 of the present embodiment, even if the sprinkler pipe 3 is attached to the square pipe 4 in the back of the ceiling, the tool is fixed by inserting a tool from the sprinkler opening 7. The fixing of the sprinkler pipe 3 by the tool 1 can be released. In addition, after performing the work such as inspection of the sprinkler head 2 in a state where the fixing of the tube fixing tool 1 is released, a tool is inserted from the sprinkler opening 7 and the pipe 3 for the sprinkler 3 by the tube fixing tool 1 is again inserted. Can be fixed.

  The tube fixing tool 1 can be released and fixed by rotating the long bolt 41 by the number of rotations necessary for releasing and fixing by the second protrusion 49 regardless of the movement amount of the sprinkler pipe 3. Since it is good, compared with the case where the rotation for the moving amount | distance of the sprinkler piping 3 is required conventionally, work can be performed easily and rapidly.

  Next, a modification of the tube fixture of the present invention will be described with reference to FIGS. As shown in FIG. 9, the tube fixture 1a of the present modification is different from the above embodiment in the shape of the second protrusion 49a of the tube contact member 42a. In addition, about the structure same as the said embodiment in this modification, detailed description is abbreviate | omitted by attaching | subjecting the code | symbol same as the said embodiment in drawing.

  As shown in FIG. 9, the second protrusion 49 a of the tube contact member 42 a in the tube fixture 1 a of this modification has both left and right (Y direction) ends of the portion that contacts the outer peripheral surface of the sprinkler pipe 3. The portion is a side support portion 54 extended toward the square pipe 4 side (X direction).

  As shown in FIG. 10, when the square pipe 4 and the sprinkler pipe 3 are fixed by the tube fixture 1a, the side support portion 54 wraps around to the outer peripheral side face of the sprinkler pipe 3 and supports the side face. It has a structure to do. Also in this modification, the surface 52 of the second protrusion 49a that faces the sprinkler pipe 3 is provided with irregularities 52 that match the shape of the cover 5 of the sprinkler pipe 3.

  According to this tubular body fixture 1a, since the side surface support portion 54 of the second protrusion 49a supports the outer peripheral side surface of the sprinkler pipe 3, the displacement of the sprinkler pipe 3 in the Y direction is prevented. It can be surely prevented. Further, since the second protrusion 49a of the tube contact member 42a is provided by the outer member 43 and the inner member 44 so as to be separated from each other in the axial direction (Z direction) of the sprinkler pipe 3, this side support portion 54 is provided. Thus, the inclination of the sprinkler pipe 3 in the axial direction can be prevented.

  In addition, in each said embodiment, although the pipe body fixing tools 1 and 1a were demonstrated as a fixing tool which fixes the piping 3 for sprinklers to the square pipe 4, it is not restricted to this, A pipe body so that it may cross | intersect with a support | pillar As long as it is fixed, it can be used for other purposes. Moreover, in the said embodiment, although the support | pillar holding | maintenance part 10 and the tube body holding | maintenance part 40 are mainly formed using the metal plate, it is not restricted to this, It is good also as a product made from synthetic resin, and using members, such as die-casting.
