Abstract

PROBLEM TO BE SOLVED: To facilitate fixing an electric wire protecting pipe. SOLUTION: A pillow member 10 for mounting an electric wire protecting pipe 1 is constituted of a hallow metal mold material. The surface on which the pipe 1 is mounted leaves engaging edges on both sides, and a slit 12 is longitudinally formed in the central part. A U band 30 is constituted of a metal belt, which is slightly wider than the slit 12 of the pillow member 10. Notches 31 are formed in the vicinity of tip of the single leg of the band 30. The part beyond the notches forms a T-shaped hook which hangs up in both of the engaging edges 11 of the pillow member. The tip of the other leg of the U band 30 is bent outside. A setscrew 36 is inserted in a hole 35, formed in a bent part 33 of the U band. A press nut 37 is screwed to the tip of the setscrew 36 and fixed temporarily. The press nut 37 is a parallelogram, when viewed from above. The distance between the long sides is made slightly smaller than the width of the slit 10 of the pillow member.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an electric wire protection pipe,
The present invention relates to a mounting bracket for fixing to a wall or a ceiling of a building.

[0002]

2. Description of the Related Art A mounting bracket for an electric wire protection pipe, which has been widely used, will be described with reference to FIG. Pillows 10 called "ductors" are attached to the walls and ceiling of the building at intervals. The pillow material 10 is hollow, and the surface on which the electric wire protection pipe 1 is mounted has a slit 1 at the center, leaving the engaging edges 11 on both sides.
2 runs vertically. An electric wire protection pipe 1 is applied to the pillow material 10 and a band 2 called a duct clip is attached.
Fixed at 0.

[0003] The band 20 is divided into two parts, and when combined, they form a U-shape. The tip of the foot of each strap 20 is formed with a T-shaped hook 21 so as to be hooked on both engaging edges 11 of the pillow material. A bent portion 22 is formed at the head of both metal bands 20, and one bent portion has a large hole 24 through which a set screw 23 passes, and the other has a tapped hole into which a set screw is screwed (illustrated in the drawing). Not).

In use, each leg (T-shaped hook 21) of the two straps 20 is hooked on the engaging edge 11 of the pillow material, the electric wire protection pipe 1 is hung from both sides, and both straps are set with set screws 23. Tighten the money 20.

[Problems to be solved by the invention]

[0005] Such a conventional mounting bracket has a drawback in that it takes time and effort to work on site because the pipe must be tightened through a set screw after being embraced by the pipe.
When many large and small electric wire protection pipes are attached side by side, the adjacent electric wire protection pipes may hinder the fastening of the setscrew. Furthermore, since the bent portion 22 of the metal band protrudes above the pipe, the worker may be injured by this.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mounting bracket for an electric wire protection pipe which can be mounted more easily.

[0007]

A metal fitting for an electric wire protection pipe according to the present invention is provided with an elongated pillow material placed on the electric wire protection pipe in an intersecting manner, and a U band fixed to the pillow material so as to hold the pipe. Consists of The pillow material is hollow, and the surface on which the pipe rests has a slit vertically extending through the center, leaving engagement edges on both sides. The U band is formed as a T-shaped hook so that the tip of one foot is hooked on both engaging edges of the pillow material. The tip of the other foot of the U-band is bent outward, and the set screw is passed through a hole formed in the bent portion, and passes through a slit when the tip of the set screw is turned in a specific direction. It is made by screwing a presser nut that can be used.

[0008]

[Effect] A pillow material is attached to a building wall, etc., an electric wire protection pipe is placed thereon, and a T-shaped hook formed at the tip of one foot of the U band is engaged with both sides of the slit of the pillow material. Hook on the rim. In this state, the U band is put on the electric wire protection pipe, the holding nut is inserted into the pillow through the slit, and the set screw is tightened.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 2, an electric wire protection pipe 1 is placed on an elongated pillow material 10 attached to a wall or a ceiling of a building at substantially regular intervals. They are placed in an intersecting manner and are fixed to this pillow material by a U-band 30. The pillow material 10 is the same hollow metal mold material as that of FIG. 1, and the surface on which the pipe 1 is mounted
A slit 12 extends vertically in the center except for 1.

The U-band 30 is formed of a metal band slightly wider than the slit 12 of the pillow material. A notch 31 is provided near the tip of one of the feet, and the U-band 30 is provided with a notch. However, it forms a T-shaped hook 32 which hooks on both engaging edges 11 of the pillow (see also FIG. 3). This T-shaped hook 3
2 has the same shape as that previously formed on the metal band 20 of FIG.

The tip of the other foot of the U-band 30 is bent outward, and a set screw 36 is inserted into a hole 35 formed in the bent portion 33.
, And a holding nut 37 is screwed into the end of the set screw 36 to temporarily fix it. The presser nut 37 is a parallelogram when viewed from above, and the distance between the long sides is determined by the slit 10 of the pillow.
(See also FIG. 5).

When used, the T-shaped hook 32 formed at the tip of one foot of the U-band 30 is inserted into the slit 12 of the pillow material.
And hook it on the engaging edge 11 (FIG. 3). Thus, while the T-shaped hook is hooked on the engaging edge,
The band 30 is put on the electric wire protection pipe 1. Next, the holding nut 37 temporarily fixed to one side of the U-band 30 with the set screw 36 is passed through the slit with its longitudinal direction facing the same direction as the slit 12 as shown by a chain line in FIG. Push in.

In this state, when the set screw 36 is turned by a screwdriver, the presser nut 37 rotates together at first, but when the presser nut 37 rotates to the position shown by the solid line in FIG. Become. When the set screw 3 is tightened in this way, the U band 30 is drawn to the pillow material, and the wire protection pipe 1 is fixed (FIG. 4).

[0014]

As described above, according to the present invention, U
A T-shaped hook is attached to one leg of the band, a set screw is attached to the tip of the other leg, and a holding nut that passes through a slit in the pillow is screwed temporarily to the tip of the screw. The wire protection pipe can be firmly fixed to the pillow material only by fitting the pillow into the pillow material, pushing the holding nut through the slit into the pillow material and tightening the set screw. In particular, unlike the conventional one, the band is not divided into two parts, so that it is not necessary to combine and tighten the band on site and the workability is excellent.
Further, even when the electric wire protection pipes are running adjacent to each other, a screwdriver can be inserted between the pipes to tighten the set screws, and the screws can be easily tightened.
