BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension band for a pipe used for hanging a pipe such as gas or water from a ceiling or the like.

[0002]

2. Description of the Related Art As a suspension band for piping, the structure shown in FIG. 9 is widely used. The prototype of this type is disclosed in Japanese Utility Model Publication No. 29-12480. In this type of suspension band for piping, the upper end of a suspension bolt 1 is fixed to an internal thread of an insert embedded in a ceiling slab, and a turnbuckle 3 is attached to the suspension bolt 1 via a nut 2 so as to be adjustable in height. The pipe 8 is fixed by tightening each end of the suspension bands 5A and 5B connected to both legs 3A and 3B of the turnbuckle 3 by the hinge mechanism 4 with bolts 6 and nuts 7. Various types of modifications of this configuration have been proposed or implemented.

In the actual work, the work of fixing the illustrated suspension band for piping to the insert embedded in the ceiling slab is performed in advance, and then the work of actually fixing the pipe 8 is performed. When fixing the pipe 8, the nut 7 is removed once, the side of the hanging band 5B is released, the pipe 8 is passed through the inside, and then the hanging band 5B is returned to the original position and tightened by the nut 7. .

[0004] On the other hand, the conventional standing band is the actual band 54-
45536, Japanese Utility Model Publication No. 57-190978, and the like. The structure is stopped by two sets of bolts and nuts, or one set of bolts and nuts and locking portions.

[0005]

In the hanging band for piping shown in FIG. 9, the bolt holes prepared at the ends of the legs 3A and 3B of the turnbuckle 3 and the hanging bands 5A and 5B are so-called stupid holes. Therefore, when the nut 7 is removed at the stage of attaching the pipe 8 and the hanging band 5B is released to the state shown by the imaginary line, the bolt 6 often comes off from the intermediate fitting 3. Therefore, it is necessary to temporarily fix the nut 7 removed to release the suspension band 5B to the bolt 6 again.

In this respect, the following configuration is known as a technique with improved workability. That is, Japanese Utility Model Application Laid-Open No.
In the technique disclosed in Japanese Patent Publication No. 5 (1993), a turnbuckle and a suspension band are riveted to each other with a fastening band. The technique disclosed in Japanese Utility Model Publication No. 56-35588 has a structure in which a turnbuckle and a suspension band are integrally formed, and a projection provided at the tip of the suspension band is hooked into a hole formed at the base of the suspension band. is there. 4-10759
In the technique disclosed in Japanese Patent Publication No. 2 (1993) -1995, a turnbuckle and a suspension band with a lower end released are integrally formed, and a bolt and nut are rotatably fixed to one of the lower end release portions of the suspension band, and a lower end release portion of the suspension band is formed. Is inserted into the notch provided on the other side and tightened. Shokai 63-4528
The technique disclosed in Japanese Patent Publication No. 1 is configured such that a turnbuckle is also used as a suspension band, and is screwed to a full-screw support rod screwed to the turnbuckle with a nut rotatably fixed to a tip of the suspension band. .

However, the above-mentioned techniques (1) to (4) are not sufficient in improving workability and are not satisfactory in terms of manufacturing cost.

The inventor of the present invention has disclosed in Japanese Patent Application No. 7-256826-7 a pipe suspension band which eliminates the above-mentioned poor workability and can easily perform the work of supporting (attaching) the pipe. However, in the subsequent research, there was room for further improvement in terms of production cost, and the present invention was achieved.

In a conventional stand band, a pair of band portions integrated by a hinge mechanism or a combination mechanism holds a pipe, and the end portions of both band portions are fixed to a wall surface, a floor or the like with bolts and nuts. The pipe is supported by being fixed to a supporting member. Explaining the conventional hanging band 5 shown in FIG. 9, instead of the hanging bolt 1, the nut 2 and the turnbuckle 3, it is fixed to a wall surface, a floor or the like. For example, T
This corresponds to a form using a character-shaped support member. Similar to the above-mentioned conventional hanging band, such a conventional stand band also has problems to be solved such as improvement of workability and reduction of manufacturing cost.

As is apparent from the above, it is an object of the present invention to provide a piping suspension band and a piping stand band which have improved usability and are satisfactory in terms of manufacturing cost.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A suspension band for piping according to the present invention will be described with reference to FIGS.

In FIG. 1, a suspension bolt 1 is fixed at its upper end side to an internal thread of an insert embedded in a ceiling slab, and the height of a turnbuckle 3 can be freely adjusted on the suspension bolt 1 via a nut 2. Attached to the
Each end of suspension bands 5A and 5B connected to both legs 3A and 3B of the turnbuckle 3 by a hinge mechanism 4 (which may be a hinge type, a combination type, or a lantern type) is attached to a bolt 6 and a nut 7. The pipe 8 is fixed by being attached by.

In the conventional suspension band shown in FIG. 9, both legs 3A and 3B of the turnbuckle 3 and the upper ends of the suspension bands 5A and 5B are fastened with ordinary bolts and nuts. Therefore, the above-mentioned inconvenience is caused.

Therefore, as shown in FIG. 1, the upper end of one suspension band 5A and both leg portions 3A and 3B of the turnbuckle 3 are provided.
And 6 are connected by a bolt 6, and the bolt 6 is fixed by a clip 9 so as to prevent the bolt 6 from falling off and to be rotatable.
The attachment position of the clip 9 is not limited to between the leg portions 3A and 3B as shown in the drawing, but may be outside the leg portion 3B.

The nut 7 is fixed by a method such as hard caulking (including so-called stepped nut caulking), welding, and adhesion so as not to be accompanied by rotation of the bolt.

In the embodiment shown in FIG. 1, one suspension band 5 is used.
The upper end of A and the leg portions 3A and 3B of the turnbuckle 3 are connected, and the nut 7 is fixed so as not to rotate. Therefore, even if the bolt 6 is rotated, the nut 7 does not rotate.

The nut 7 may be a normal nut, but it is preferable that the nut 7 has an opening that is open outward so that the tip of the bolt 6 can be guided to the female screw portion.

The embodiment shown in FIG. 2 shows an example in which the turnbuckle 3 and the suspension band 5A are formed of a single plate. Further, the nut 7 is non-rotatably fixed by a crimping method. The configuration of other parts is the same as that of the above-described embodiment.

The nut 7 may be a conventional nut in which a female screw is provided over the entire length of the internal space, but a nut having a guide hole in the preceding stage of the female screw is preferably used. . In the guide hole, the inner diameter is gradually reduced toward the female screw, and the entire hole is tapered,
It is possible to adopt a mode in which the guide hole has an inner diameter larger than the inner diameter of the female screw, and the taper is provided immediately before the female screw. It is more preferable that the portion transitioning to the taper be a curve without a step. With this configuration, in the conventional nut, it is difficult to insert the bolt without inserting the female screw from the vertical direction.
Even if the bolt 6 is inserted from an oblique direction, the tip of the bolt 6 can be easily engaged with the female screw by the action of the guide hole, and the work of engaging the bolt 6 with the nut 7 is facilitated. Is significantly improved.

In another embodiment of the present invention shown in FIG. 3, the length of the suspending band 5A is set to be larger than one half of the circumference of the pipe 8 so that the pipe can be inserted. With this configuration, even when the bolt 6 and the nut 7 are released,
The pipe 8 is supported by the suspension band 5A, and therefore does not fall off even if it is not pressed by hand.

In the embodiment shown in FIG. 3, a tapping screw 6A is used instead of the bolt 6, and a tubular opening 7A is used instead of fixing the nut 7 to the end of the suspension band 5B. Are formed. By rotating the tip of the tapping screw 6A while strongly pressing it against the cylindrical opening 7A, the tapping screw 6A enters the inside of the cylindrical opening 7A while threading and is fixed.

Furthermore, the present invention also includes a mode in which a female screw is provided in the cylindrical opening 7A and a normal bolt or screw is used instead of the tapping screw 6A.

Since the nut 7 of the conventional piping suspension band shown in FIG. 9 is provided with a female screw over the entire length of the inner space, the bolt 6 is inserted vertically from the female screw of the nut 7 and is not rotated. And, the screw thread does not mesh with the insertion in an oblique state, so it cannot be tightened. However, since the bolt 6 is fixed to the tip of the suspension band 5B, if the suspension band 5B is rotated, it may be inserted obliquely and proper insertion from the vertical direction may be difficult. Occurs.

The clip 9 will be described with reference to FIG.

The clip 9 is made of a thin iron wire (for example, about 0.7 mm) having elasticity. The clip 9 is formed by bending the central portion to form the ring 9A and then crossing it 9B.
Further, the extension portion is curved to form an engaging portion 9C for the bolt 6 and the remaining portion is crossed 9D to form an extension portion 9E. The elasticity is generated by the ring 9A and the intersection 9B, and the diameter of the engaging portion 9C can be increased by pressing the extension 9E in the sandwiching direction. When the pressed extension 9E is released, the engaging portion 9C is released. Is restored by elasticity, and the bolt 6 is pinched. Therefore, the clip 9 can be attached to the bolt 6 very easily.

Further, since the iron wire is twisted at the intersection 9B and the intersection 9D, when the bolt 6 is attached to the nut 7, it functions like a washer and prevents the bolt 6 from loosening. There is. In contrast to the above, it is also possible to adopt a configuration in which the twist is not made.

The above-mentioned clip 9 can be formed of a thin iron wire, a metal wire such as a copper wire or an aluminum wire, or a synthetic resin material.

5 to 7 show another embodiment of the clip 9.

In the embodiment shown in FIG. 5, instead of the ring 9A of the clip 9 shown in FIG. 4, elasticity is imparted as a triangular configuration, a bolt engaging portion 9C is formed in the central portion, and an extension portion 9E is formed. The engaging portion 9C can be easily engaged with the bolt 6 simply by pushing the bolt 6 from the side.

The embodiment shown in FIG. 6 is similar to the clip 9 shown in FIG. 4 in that the elasticity of the ring 9A is utilized,
This is a configuration without the intersections 9B and 9D. As in the embodiment shown in FIG. 5, a bolt engaging portion 9C is formed at the center, and only by pushing the bolt 6 from the side of the extension 9E,
The engaging portion 9C can be engaged with the bolt 6.

As described above, in the embodiment of the clip 9 described with reference to FIGS. 4 to 6, a groove may be annularly provided on the side of the bolt 6 in order to make the mounting position of the clip 9 accurate.

In the embodiment shown in FIG. 7, the clip 9 is formed in a substantially R shape, the linear portion is inserted into the pin hole provided in the bolt 6, and the elasticity of the ring 9A portion is utilized to make the bolt engaging portion 9
This is a configuration for preventing the bolt 6 held in C from falling off. If you pull the extension 9E away from the straight part,
It can be removed from the bolt 6. In this embodiment, unlike the other embodiments described above, the position of the clip 9 does not move in the direction of the head of the bolt 6 according to the rotation of the bolt 6, so that the pin hole into which the straight portion of the clip 9 is inserted is not provided. , Must be provided at a position close to the head of the bolt 6.

Even in the clip 9 of the embodiment shown in FIG. 7, the bolt 6 may be attached to the bolt 6 in the same manner as the clip 9 of the other embodiments described above without providing a pin hole. It is possible.

The tip of the bolt 6 is pushed into the opening of the nut 7 and guided to the female screw. At this time, the opening of the end of the suspension band 5B through which the bolt 6 is penetrated is made a long hole, and the bolt 6 is moved. With such a configuration, the operation of engaging the bolt 6 with the nut 7 becomes simple.

When the bolt 6 engaged with the female thread of the nut 7 is rotated, in the embodiment shown in FIG. 1, the leg portion 3A and the leg portion 3B are rotated.
The clip 9 is deformed in the direction in which
It is pushed by the inner side surface of B and moves in the direction of the leg portion 3A. The final position of the clip 9 is determined by the final tightened position of the bolt 6. In the mode shown in FIGS. 2 and 3, the clip 9 is pushed by the nut 7 that moves as the bolt 6 is tightened, and moves to the leg 3B side.

Next, referring to FIG. 8, a vertical pipe band according to the present invention will be described.

The pipe stand band 10 is composed of a pair of band portions 11 and 12 for holding the pipe and a support member 13 for fixing the band portions 11 and 12 to a wall surface or the like. The support member 13 is a substrate 14 that is fixed to a wall surface or floor by concrete nails or the like.
And a support plate 15 which is erected from the substrate 14, and the support plate 15 is provided with an opening 16 composed of a long hole or a plurality of circular holes.

The structure of the support member 13 is not limited to the illustrated embodiment, and the base portion of the support plate 15 may be screwed to an anchor driven into a wall surface or floor.

A tapping screw 17 is arranged in an opening provided at an end of one band portion 11 of the stand band 10, and the tapping screw 17 is opened by the clip 9 described with reference to FIGS. It is fixed so that it does not fall out. Tapping screw 17
Is configured so that it can be easily rotated even when fixed by the clip 9.

A cylindrical opening 18 is prepared at the end of the other band portion 12. The configuration of the tubular opening 18 is the same as the configuration of the tubular opening 7A described with reference to FIG. Therefore, the tip of the tapping screw 17 is attached to the cylindrical opening 1
By pressing firmly against 8 and rotating it, the inside of the cylindrical opening 18 is threaded and penetrates,
The end portions of the band portions 11 and 12 are provided with the support plate 15 of the support member 13.
It will be firmly fixed with the sandwiched between. As the tapping screw 17 is tightened, the clip 9 comes into contact with the peripheral edge of the tubular opening 18 and receives pressure, so that the clip 9 is pushed toward the head of the tapping screw 17.

The present invention also includes a mode in which a bolt is fixed in place of the tubular opening 18, a mode in which a screw or a bolt is used in place of the tapping screw 17, and a mode in which a female screw is provided inside the tubular opening 18. Included.

Further, as described in the prior art, it goes without saying that the present invention can be applied to a stand band constructed so as to be stopped by a set of bolts and nuts and locking portions.

[0045]

According to the suspension band for piping according to the present invention, even when the bolt and the nut are released when the piping is mounted, each of the bolts and nuts falls off from the leg of the turnbuckle or the end of the suspension band. There is no. Therefore, it is not necessary to hold down the bolts and nuts and temporarily fix them, which were required in the conventional work using a suspension band.In addition, when tightening the bolts and nuts, the bolts can be easily attached vertically to the female thread of the nut. Since it can be placed in various postures, it has the advantage of being extremely convenient to use and significantly improving work efficiency.

Furthermore, if a clip formed of a thin iron wire having elasticity is used as a clip for fixing the bolt to one end of the suspension band in a rotatable state, the end of the clip is slid to engage the bolt. You can easily and securely attach to the threaded part of the bolt simply by opening the part, for example,
Compared to a method in which a synthetic resin ring is fitted into the bolt thread, the assembly work is extremely simple, which is advantageous in reducing production costs. Further, by using a metal, unlike a synthetic resin, there is an advantage that no toxic gas or the like is generated in a fire.

According to the pipe stand band of the present invention,
By simply rotating the tapping screw attached to the end of one band via a clip, the tubular opening formed at the end of the other band enters and fixes while tapping. Since it works, it is not only very convenient to use, but also extremely useful in reducing the manufacturing cost as compared with the conventional fixing using bolts and nuts.

Further, in the mode in which the female screw is provided inside the tubular opening, it is convenient to use ordinary bolts or screws instead of the tapping screw, and the piping work can be performed efficiently. is there.
