BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing device for a sprinkler pipe provided on a ceiling.

[0002]

2. Description of the Related Art Conventionally, a pipe A for a sprinkler disposed on a ceiling is composed of a straight pipe Aa and an elbow joint Ab as shown in FIG.
And was spliced. However, in recent years, flexible pipes have been used as sprinkler pipes because of ease of construction and the like, and a fixing device capable of firmly fixing the sprinkler pipe is required. ing.

As a conventional sprinkler pipe fixing device, as shown in FIG. 8, a support member E which is installed on a ceiling base material D by a mounting bracket C, and a sprinkler pipe A which is supported by the support member E are used. Some are provided with a fixing bracket F for fixing.

[0004]

However, the above-mentioned fixing device has a problem that it cannot be used on a ceiling without a ceiling base material, that is, a so-called 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 a sprinkler pipe on an exposed ceiling.

[0006]

In order to achieve the above object, a sprinkler pipe fixing device according to the present invention comprises a hanging bolt suspended from a ceiling, a pair of opposed pieces and a connecting piece.
And the opposing pieces are opposed in the axial direction of the suspension bolts.
To the hanging bolts
This is to fix the pipes for anchors parallel to the suspension bolts.
Therefore, the tip end side of each opposing piece is formed in a bifurcated shape and suspended.
Mounting parts that can be attached to the bolts from the side are provided.
Sprinkler piping is hung on the base end side of each facing piece
There is an insertion hole inserted in parallel with the bolt, and the connecting piece
A fixing fitting with a female screw, and a male screw member that presses the sprinkler pipe by screwing into the fixing fitting's female screw,
.

[0007]

According to this structure, the sprinkler pipe inserted into the insertion portion of the fixing fitting is pressed and fixed by the male screw member, and the fixing fitting is attached to the suspension bolt suspended from the ceiling. Can be fixed. In addition, since the fixing bracket 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 tightening state of the male screw member can be visually checked.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The fixing device of the sprinkler pipe according to the present invention includes a hanging bolt 1 suspended from a ceiling, a fixing fitting 2 attached to the hanging bolt 1 to fix the sprinkler pipe T, and a male screw member screwed to the fixing fitting 2. 8 is provided.

The suspension bolt 1 is a rod-shaped member used for suspending a pipe or the like, and has a male screw engraved on the entire surface or on both ends. The suspension bolt 1 is screwed to an insert having a female screw provided on the exposed ceiling in accordance with the position where the sprinkler head is provided, and hangs from the ceiling. Further, the suspension bolt 1 can be cut into a required length as needed.

[0010] As shown in FIG.
The opposing pieces 3, 3 and the connecting piece 4 form a substantially U-shape.
Hanging bolt so that 3 faces the hanging bolt 1 in the axial direction
1 and sprinkler piping T
Is fixed in parallel with the suspension bolt 1. Opposing piece 3
As shown in FIG. 3, a sprinkler
Hole through which the piping T is inserted in parallel with the suspension bolt 1.
5 is provided. The pipe insertion hole 5 is formed slightly larger than the outer diameter of the sprinkler pipe T. The mounting tip portion side of the facing plates 3 is formed in a bifurcated shape is notched in a substantially U shape from the front end to the center, the cutout portion, to be attached laterally to the suspension bolt 1 When
And the hanging bolt insertion portion 6. The fixing bracket 2 is fixed to the suspension bolt 1 by inserting the suspension bolt 1 through the suspension bolt insertion portion 6 and tightening the nut member N screwed to the suspension bolt 1.

Further, the distal end of the opposing piece 3 is bent in a direction away from each other, and forms a locking portion 7 which locks to the nut member N to prevent the fixing bracket 2 from dropping from the hanging bolt 1. ing.

Further, a female screw is cut into the connecting piece 4 of the fixture 2. The male screw member 8 is screwed to the female screw. The sprinkler pipe T is pressed and fixed by tightening the male screw member 8 while the sprinkler pipe T is inserted into the pipe insertion hole 5 of the fixture 2. At this time, the tightening state of the male screw member 8 can be viewed from the side. That is, the sprinkler pipe T can be fixed while visually checking the tightened state.

[0013] Piping for sprinkler by this fixing device
Explaining the fixing of T 1, first, the suspension bolt 1 is screwed to an insert provided at a predetermined position, and a plurality of nut members N are screwed to the suspension bolt 1. Next, the fixing bracket 2 is attached so that the suspension bolt 1 is inserted into the suspension bolt insertion portion 6, and the nut member N is tightened. Thereby, the fixing fitting 2 is fixed to the suspension bolt 1. Next, the sprinkler pipe T is inserted into the pipe insertion hole 5 of the fixture 2. Then, the fixing height is adjusted, and the male screw member 8 is screwed into the female screw of the fixing fitting 2 and tightened, whereby the sprinkler pipe T is fixed at a predetermined position.

When the sprinkler pipe T is fixed by the fixing device described above, the stability of the suspension bolt 1 may be increased by using a stabilization aid 9 as shown in FIGS. . The stabilization aid 9 is
And an upwardly inclined piece that inclines obliquely upward from both ends of the connecting piece 10
Consists of 11,11. Further, the tip of the upper inclined piece 11 is bent obliquely downward to form a lower inclined piece 12. Connecting piece 10
In this case, a suspension bolt insertion portion 10a is formed by notching. Further, the downwardly inclined piece 12 is provided with a suspension bolt insertion hole 12a.

The stability assisting tool 9 is obtained by superposing the connecting piece 10 on the opposing piece 3 of the fixing bracket 2, inserting the hanging bolt 1 hanging from the ceiling through the hanging bolt insertion portion 10a, and tightening the nut member N. ,It is attached. Then, when another suspension bolt H is inclined and inserted into the suspension bolt insertion hole 12a of the downward inclined piece 12, and the nut member N is tightened,
The stability of the hanging suspension bolt 1 is increased.

Either of fixing the sprinkler pipe and attaching the fixing bracket to the suspension bolt may be performed first. Also, adjustment of the fixed height of the sprinkler head,
It may be performed 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, and for example, an insertion hole may be provided.

[0017]

[Effect of the Invention] The sprinkler pipe fixing device of the present invention presses and fixes the sprinkler pipe to be inserted into the insertion portion of the fixing bracket with a male screw member, and attaches the fixing bracket to a suspension bolt suspended from the ceiling. Under the ceiling
On an exposed ceiling with no base material, suspenders hanging from the ceiling
Orient the sprinkler piping vertically by using
Can be fixed. In addition, hanging extending vertically
The fixing bracket can be attached to the bolt from the side.
Therefore, the distribution for sprinklers using suspension bolts
The tube can be easily fixed. Further, since the fixing bracket has a substantially U-shaped cross section including the opposing 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 observed. Therefore, the fixed state of the sprinkler pipe can be easily recognized.
