Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixing device for a sprinkler pipe arranged on a ceiling.

[0002]

[Prior art]

 Conventionally, the sprinkler pipe A arranged on the ceiling is a joint of a straight pipe Aa and an elbow joint Ab, as shown in FIG. Recently, however, flexible pipes have been used as sprinkler pipes because of their ease of construction, and it is necessary to have a fixing device that can firmly fix the sprinkler pipes. Has become.

As a conventional fixing device for a sprinkler pipe, as shown in FIG. 8, a supporting member E laid on a ceiling base material D by a mounting tool C and a sprinkler pipe A supported by the supporting member E. Some have a fixing bracket F for fixing the.

[0004]

[Problems to be solved by the device]

 However, the fixing device described above has a problem that it cannot be used on a ceiling without a ceiling base material, that is, an exposed ceiling. That is, the support member cannot be installed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sprinkler pipe fixing device capable of fixing the sprinkler pipe in an exposed well.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the fixing device for the sprinkler pipe of the present invention is a suspension bolt hung from the ceiling and a substantially U-shaped cross section composed of a facing piece and a connecting piece. A fixing bracket that has an insertion part for the sprinkler pipe and a mounting part for the hanging bolt, and has a female screw engraved on the connecting piece, and a male screw member that is screwed into the female screw of the fixing bracket to press the sprinkler pipe. , Is provided.

[0007]

[Action]

 According to this configuration, the sprinkler pipe that is inserted through the insertion part of the fixing bracket is pressed and fixed by the male member, and the fixing bracket is attached to the hanging bolt that is hung vertically from the ceiling, so that it can be used for sprinklers on exposed ceilings. The pipe can be fixed. In addition, since the fixing metal fitting has a substantially U-shaped cross section composed of the facing piece and the connecting piece, and the male screw member is screwed into the female screw engraved on the connecting piece, the tightened state of the male screw member can be visually checked.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. The device for fixing the pipe for the sprinkler of the present invention comprises a suspension bolt 1 which is hung vertically from the ceiling, a fixture 2 which is attached to the suspension bolt 1 and which fixes the sprinkler pipe T, and a male screw which is screwed to the fixture 2. The member 8 is provided.

The suspension bolt 1 is a rod-shaped member used when suspending a pipe or the like, and has male screws engraved on the entire surface or both ends thereof. The hanging bolt 1 is screwed to an insert having an internal thread provided on the exposed ceiling in accordance with the position where the sprinkler head is arranged, and hangs down from the ceiling. Further, the hanging bolt 1 can be cut into a desired length and used.

The fixing member 2 is composed of facing pieces 3 and 3 and a connecting piece 4, and has a substantially U-shaped cross section. The opposed piece 3 is provided with a pipe insertion hole 5 through which the sprinkler pipe T is inserted. The pipe insertion hole 5 is formed slightly larger than the outer diameter of the sprinkler pipe T 1. Further, the facing piece 3 is cut out in a substantially U-shape from its tip to the center, and the cutout portion serves as the hanging bolt insertion portion 6. The fixing bracket 2 is fixed to the suspension bolt 1 by inserting the suspension bolt 1 into the suspension bolt insertion portion 6 and tightening the nut member N screwed to the suspension bolt 1.

Further, the tip end of the facing piece 3 is bent in a direction away from each other, and is engaged with the nut member N to prevent the fixing metal fitting 2 from falling off the hanging bolt 1. Is becoming.

Further, the connecting piece 4 of the fixing member 2 is engraved with a female screw. The male screw member 8 is screwed into this female screw. By tightening the male screw member 8 with the sprinkler pipe T inserted in the pipe insertion hole 5 of the fixing bracket 2, the sprinkler pipe T is pressed and fixed. At this time, the tightened state of the male screw member 8 can be visually observed from the side. That is, the sprinkler pipe T can be fixed while visually checking the tightened state.

The fixing of the sprinkler pipe T 1 by this fixing device will be described. First, the suspension bolt 1 is screwed to the insert provided at a predetermined position, and a plurality of nut members N are screwed to the suspension bolt 1. Next, the fixing metal fitting 2 is attached so that the hanging bolt 1 is inserted into the hanging bolt insertion portion 6, and the nut member N is tightened. As a result, the fixing bracket 2 is fixed to the suspension bolt 1. Next, the sprinkler pipe T is inserted into the pipe insertion hole 5 of the fixing bracket 2. Then, the fixing height is adjusted, and the male screw member 8 is screwed onto the female screw of the fixing member 2 and tightened, whereby the sprinkler pipe T is fixed at a predetermined position.

By the way, when the sprinkler pipe T is fixed by the above-mentioned fixing device, even if the stability of the suspension bolt 1 is increased by using a stabilizing aid 9 as shown in FIGS. 5 to 7. Good. The stabilizing aid 9 is composed of a connecting piece 10 and upward slanting pieces 11 and 11 slanting upward from both ends of the connecting piece 10. Further, the tip end portion of the upper inclined piece 11 is bent obliquely downward to form a downward inclined piece 12. The connecting piece 10 is formed with a hanging bolt insertion portion 10a as a cutout. In addition, the lower inclined piece 12 is provided with a hanging bolt insertion hole 12a.

In this stabilizing aid 9, the connecting piece 10 is superposed on the facing piece 3 of the fixing metal fitting 2, the hanging bolt 1 hanging from the ceiling is inserted into the hanging bolt insertion portion 10a, and the nut member N is tightened. To be installed. Then, when another suspension bolt H is tilted and inserted into the suspension bolt insertion hole 12a of the downwardly inclined piece 12 and the nut member N is tightened, the stability of the hanging suspension bolt 1 is increased.

Either the fixing of the sprinkler pipe or the attachment of the fixing fitting to the suspension bolt may be performed first. The fixed height of the sprinkler head may be adjusted by loosening the male screw or the nut member. Further, the insertion portion of the suspension bolt is not limited to the U-shaped notch, but may be provided with an insertion hole, for example.

[0017]

[Effect of device]

 Since the device for fixing the sprinkler pipe of the present invention presses and fixes the sprinkler pipe that is inserted through the insertion portion of the fixing bracket with the male screw member, and the fixing bracket is attached to the hanging bolt that is hung vertically from the ceiling, the exposed ceiling At, the sprinkler pipe can be fixed. Further, since the fixing metal fitting is made into a substantially U-shaped cross section composed of the facing piece and the connecting piece, and the male screw member is screwed into the female screw engraved on the connecting piece, the tightening state of the male member can be visually checked. . Therefore, it becomes easy to recognize the fixed state of the sprinkler pipe.
