DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art A conventional pipe hanger is provided with a flanged nut through a circular hole in an upper horizontal plate, and both sides of the plate are bent vertically downward to be bent at an intermediate portion. In general, a suspended portion composed of a pair of plates is provided at a lower portion with a small distance between the bolts, and a pair of plates of the suspended portion are provided with circular holes for bolts in the horizontal direction.

[0003]

In this conventional pipe suspender, the bolt is suspended at the time of pipe installation work such as connecting the suspender and the suspending band with bolts and holding the pipe with the suspending band. When the bolt is inserted into one of the circular holes for the bolts and the circular hole for the bolts of the hanging tool, the bolts of the bolts are rounded due to the circular shape of the circular hole for the bolts of the lifting tool and the weight of the bolt head and the weight of the lifting band. Since the head side is inclined diagonally downward and the tip of the screw part of the bolt is inclined diagonally upward, the bolt can be removed relatively easily from the bolt hole circular hole of the hanging tool. There was a problem that it would fall off more.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the pipe hanger, prevents the bolt from dropping out of the bolt through hole of the pipe hanger, and facilitates pipe installation work. It is intended.

[0005]

According to the present invention, there is provided a hanging device for a pipe according to the present invention, wherein a locking claw having a thickness smaller than the thickness of a plate is inserted into a bolt hole circular hole provided in one plate of a hanging portion. At least one inward from the top or bottom of the perimeter of the through hole
Are provided.

[0006] In the hanging device for piping according to the present invention, at least one locking claw is provided in the bolt through circular hole provided in one plate of the hanging portion from the upper or lower part of the periphery of the bolt through hole toward the inside. So, if you insert the bolts horizontally into the bolt holes on one side of the suspension band and the bolt holes on the lifting device,
Because the bolt head side is inclined obliquely from the horizontal direction by the weight of the bolt head and the weight of the suspension band, the locking claw of the lifting device is locked at the bottom of the valley between the screw threads of the bolt. The bolts and the suspension band are prevented from dropping out of the bolt through holes of the lifting device, and the pipes are easily installed because the falloff prevention is performed. In addition,
Similarly, in the case where only the bolt is inserted into the bolt through hole of the hanging tool in preparation for pipe installation work or the like, the bolt is similarly prevented from being inclined obliquely and falling off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS.
An upper horizontal metal plate 1 is provided with a flanged nut through circular hole 2 in a horizontal metal plate 1, and both sides of the metal plate 1 are bent vertically downward to reduce the distance between the metal plates 1 bent at an intermediate portion. In the lower part, a hanging portion 3 composed of a pair of metal plates 1 ', 1 "is provided. A circular hole 4 is provided in each of the pair of metal plates 1', 1". Provide. Further, a locking claw 5 having a thickness smaller than the thickness of the metal plate 1 is inserted into the bolt hole circular hole 4 provided on one of the metal plates 1 ′ of the hanging portion 3 from the upper part of the periphery of the bolt hole circular hole. And a pipe hanging member 6 provided on the outer periphery of one of the metal plates 1 ′ and continuous with the peripheral edge of the bolt hole circular hole 4.

As shown in FIG. 5, a bolt 7 is inserted into one of the bolt passing circular holes of the suspension band 8, and the bolt 7 is inserted into the other metal plate (right side in FIG. 5). 1 "metal plate 1 'from 1" bolt hole circular hole 4
Into the circular hole 4 of the bolt. Both metal plates 1 ',
Bolt 7 inserted in 1 "bolt through circular holes 4 and 4
According to the weight of the bolt head 7 'and the weight of the suspension band 8, the right side in the drawing is inclined obliquely downward, and the left side is inclined obliquely upward. A thin locking claw 5 provided above the circular hole 4 for bolting is locked at the bottom of the valley between them as shown in FIG. Reference numeral 9 denotes a nut with a flange, and reference numeral 10 denotes a round bar with a screw in which an upper portion is fixed to a piping portion and the nut 9 with a flange is screwed in a lower portion. In addition, the locking claw 5 is one metal plate 1 '.
In the above description, the locking claw may be provided on the inside of one of the metal plates 1 ′, or on an intermediate portion between the inside and the outside, or the locking claw may be formed by pressing. It may be one obtained by welding a separate locking claw.

FIGS. 6 to 8 show hanging members for piping in which the positions and positions and the number of locking claws provided on one metal plate are changed. The locking claw 15 having a thickness smaller than the thickness of the one metal plate 11 'is continuously connected to the periphery of the bolt hole circular hole 14 from the lower part of the periphery of the bolt hole circular hole toward the inside.
(See FIG. 6). In this pipe hanging tool, one metal plate 11 'on the side where one locking claw 15 is provided.
Then, the locking claw 15 is locked at the bottom of the bolt. Similarly, two locking claws 15 are provided in the bolt hole circular hole 14 from the upper part and the lower part toward the inside (FIG. 7). Similarly, the locking claw 1 is inserted into the bolt hole circular hole 14.
5 are provided at substantially equal intervals from the upper portion and from the left and right to the inside (see FIG. 8). When there are three locking claws, three locking claws may be provided at substantially equal intervals from the lower part and the left and right sides toward the inside. Although not shown, similarly, four or more locking claws may be provided at substantially equal intervals in the bolt hole circular holes.

In the same manner as described above, the locking pawl is provided on one metal plate, and one locking pawl is provided on the other metal plate from the periphery of the circular hole with a bolt passing inward from the upper or lower portion. Alternatively, two locking claws may be provided inward from the upper and lower portions, or three or more locking claws may be provided inward at substantially equal intervals. By providing locking claws on both metal plates, the bolt is better locked by both metal plates and the plurality of locking claws. In the case where one locking claw is continuously provided on the periphery of the bolt hole circular hole of both metal plates, the position of the locking claw of one metal plate and the position of the locking claw of the other metal plate are determined. The position is best upside down (one is upper, the other is lower or vice versa). Similarly, when three locking claws are provided, it is better to turn upside down.

[0011]

According to the present invention, there is provided a hanging device for piping according to the present invention, wherein a locking claw having a thickness smaller than the thickness of a plate is provided on a bolt through hole provided in one plate of a hanging portion at an upper portion of a periphery of the bolt through hole. Or, the bolts are installed inward from the bottom, so the bolts are inserted horizontally into the bolt holes on one side of the suspension band and the bolt holes on the lifting device, so that the bolts tilt obliquely from the horizontal direction due to the weight of the suspension band and bolts. The hooks of the hanging tool are locked to the bottom of the threaded part of the bolt, so that the bolt and the hanging band can be prevented from dropping out of the bolt hole of the hanging tool, thus preventing the dropping Therefore, there is an effect that pipe installation work and the like can be easily performed.
