DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanging bracket used when piping a cold / hot water pipe or the like.

[0002]

2. Description of the Related Art As a conventional pipe suspending fitting, a circular suspending band having a cutout on the upper side and a suspending portion continuously provided at an end of the cutout of the circular suspending band are provided above, respectively. Bolt holes are provided in the hanging part.Independent bolts are inserted into the bolt holes of the pipe hanging bracket, and independent nuts are fitted to the threaded parts of the bolts and tightened. Commonly used.

[0003]

In this conventional pipe hanging metal fitting, since the hanging part, the bolt and the nut, which are continuous with the circular hanging band, are separate and independent from each other, For example, when performing pipe installation work at a high place, the worker holds the circular suspension band outside the pipe by hand in a place where it is difficult to work on a ladder, etc., while holding both of the circular suspension bands. It is necessary to insert the bolt into the bolt passage hole of the hanging part, then fit the screw end of the bolt to the nut and tighten it.
There is a problem that bolts and nuts are easy to fall off from the suspension portions of the circular suspension band, and it is difficult to fit bolts and nuts into both suspension portions of the circular suspension band, and a problem that it is difficult to tighten. There was a point.

[0004] The present invention solves these problems of the pipe hanging fittings, prevents the bolts and nuts from dropping off from the piping hanging fittings, and easily tightens the bolts and nuts to the piping hanging fittings first. It is intended to be easy to tighten.

[0005]

According to the present invention, there is provided a pipe hanging metal fitting in which a nut is fixed outside a bolt through hole provided in one hanging portion of a circular hanging band, and the other of the circular hanging band is provided. A long bolt passing long hole is provided in the hanging part in the vertical direction, and a bolt having a constricted portion near the bolt head under the bolt neck is inserted into the long bolt passing hole with the bolt head outside and this bolt is inserted. The elongated hole wall of the other hanging portion is slightly deformed inward at the constricted portion, and the bolt is rotatably supported by the other hanging portion.

In the pipe hanging bracket of the present invention, a nut is fixed to one of the hanging portions of the circular hanging band, and a bolt is rotatably supported by the other hanging portion of the circular hanging band. Therefore, the worker can easily attach the hanging fitting to the outside of the pipe, and the fitting is easily tightened by a bolt and a nut fixed rotatably to the hanging fitting. When the bolt is inserted into the nut and tightened, a vertically long bolt hole is provided in the other hanging part so that the tip of the screw part can move slightly up and down, etc. It is smoothly fitted into the nut fixed to one of the suspension portions and is smoothly tightened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS.
The circular suspension band is composed of one semicircular suspension band 1 and the other semicircular suspension band 2, and has cutouts 1 ″, 2 ″ above both semicircular suspension bands 1, 2. The hanging portions 1 ', 2' are continuously connected to the ends of the notches 1 ", 2".
2 'are respectively provided above. The lower portions of the two semicircular suspension bands 1 and 2 are connected by a hinge 3. A bolt passing hole 4 is provided in one suspension portion 1 ′, and a nut 5 is provided outside the bolt passing hole 4 by welding. The other hanging portion 2 'is provided with a vertically long bolt hole 6 in the vertical direction.
A bolt 7 having a constricted portion 8 is
With the bolt head 9 outside. The bolt 7 having the constricted portion 8 is provided near the bolt head below the bolt neck.
Having. The diameter of the bolt 7 to the bolt through the wall of the long hole 6 of the constricted portion 8 other hanging element 2 'in FIG. 5 by caulking in the horizontal direction indicated by the arrow in FIG. 4 shown in Figure 3 of the bolt 7 A hanging metal fitting for piping in which the bolt 7 is rotatably engaged with the other hanging part 2 ′ by being deformed into a smaller shape larger than the constricted part 8 and rotatably engaged with the other hanging part 2 ′. It is 10.

In this pipe hanging bracket 10, the nut 5 is welded and fixed to one hanging portion 1 ', and the bolt 7 is integrated with the other hanging portion 2'. The nut 5 is integrated with both suspension bands 1 and 2 via both suspension portions 1 'and 2' . The operator can easily attach the pipe hanging bracket 10 to the pipe.
Work can be done. Although the bolt 7 has been described as being integrated with the other hanging portion 2 ' by caulking , the method of integrating the bolt with the other hanging portion is other than caulking. Of course, any appropriate method may be used.

In the pipe hanging bracket 10, the lower part of two semicircular hanging bands is connected by a hinge as a circular hanging band. However, the circular hanging band is composed of two semicircular hanging bands. On one side, a locking hole is provided at the lower part of the semicircular suspension band, and on the other side, a protruding piece is provided at the lower part of the semicircular suspension band. It may be one that is engaged and connected, or one in which a circular suspension band is integrally formed in advance.

FIG. 6 shows another pipe suspender, which is different from the above-mentioned pipe suspender in that a nut 11 having a mounting piece 11 'is attached to one suspending portion 12'.
Nut from the outside through the bolt hole 13
1 is a pipe hanging metal fitting 14 in which the mounting piece 11 ′ is bent outward and fixed inside the bolt through hole 13 with a tool.

[0011]

According to the present invention, there is provided a pipe hanging metal fitting having a circular shape.
And the three parts of the suspension band, bolt and nut
Because provided, respectively integral to the bolt and nut can be easily attached to the operator when attaching the bracket hanging the pipe with the effect that not fall from the suspended portion of the circular hanging band pipe hanging Together with the bracket
Bolts and nuts can be easily fitted
And easily tighten the hanging bracket with bolts and nuts
Can be opened. When you fit this bolt into the nut
At the time of tightening, suspend a long bolt through long hole in the vertical direction
By installing it on one suspension part of the band,
The tip can move slightly up and down, etc.
Is fixed to the other hanging part of the suspension band
It can be smoothly fitted into the nut, and the hanging bracket
It can be easily tightened with the bolt and nut .
