In the above conventional piping suspension fitting, only a pipe having a predetermined outer diameter can be fixed.
Therefore, in the present invention, it is an object of the present invention to provide a single hanging pipe fitting that can suspend and fix pipe bodies having different pipe diameters.
Also, in order to cope with pipes of different outer diameters when fixing the pipe, it is necessary to change the length of the member that holds the pipe, and thus a pipe fixing method corresponding to this is devised. This is also an object of the present invention.
Furthermore, it is also an object of the present invention that the work can be performed more easily and conveniently when fixing the pipe.

  In order to solve the above-described problems, a first aspect of the present invention is a pipe hanging bracket that is attached to the tip of a long screw rod suspended from the top of a building structure, etc. And a band member made of a plastic thin metal strip, and the main body portion has a top portion rotatably provided with a female screw member that is screwed into the screw rod. One end portion of the band member is fixed to one side edge portion of the portion, and an extension portion extending substantially downward is provided on the other side edge portion of the top portion, and the other end serving as the free end of the band member is provided. One or more locking portions provided in the end portion in a direction substantially orthogonal to the longitudinal direction of the band member are arranged in a plurality of rows along the longitudinal direction of the band member, and the locking is performed to lock the locking portion. A receiving part is provided in the extension part of the main body part, and this band member is wound around the pipe so that it is possible to By locking the row to the lock receiving portion of the main body portion, it is possible to adapt to the outer diameter of different pipes, and then the pipe is connected by screwing the female screw member into the screw rod. A pipe suspension fitting, wherein the pipe is pressed by a tip end of a screw rod, and at the same time, the pipe is fixed by a band member.

A second one of the present invention is a hanging bracket for piping attached to the tip of a long screw rod suspended from the top or the like of a building structure, and can be plastically deformed with a metal main body. The main body portion has a top portion provided with a female screw portion into which the screw rod is screwed, and one side edge of the top portion has a band member. One end is fixed, the other side edge of the top is provided with an extension extending substantially downward, and the other end which is the free end of the band member is substantially orthogonal to the longitudinal direction of the band member 1 or 2 or more locking portions provided in the direction to be arranged in a plurality of rows along the longitudinal direction of the band member, and a locking receiving portion for locking with the locking portion is provided in the extension portion of the main body portion, The band member is wound around the pipe, and any row of the locking portions formed in a plurality of rows is locked to the locking receiving portion of the main body portion. And makes it possible to adapt the outer diameter of the different pipes,
Thereafter, the pipe is pressed by the tip of the screw rod by screwing the screw rod into the female screw portion, and at the same time, the pipe is fixed by the band member.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, there is provided a pipe hanging bracket characterized in that a grip portion is formed at the other end which is a free end of the band member.

  According to a fourth aspect of the present invention, in the first to third aspects of the present invention, one end of the band member fixed to one side edge of the main body is formed to be detachable from the main body. This is a characteristic hanging bracket for piping.

In the first aspect of the present invention, since the band member is formed of a metal thin strip and is plastically deformable, the band member is adapted to a pipe body having a different pipe diameter and is along the outer peripheral surface of the pipe body. Can be deformed appropriately.
The free end portion of the band member is provided with a plurality of rows of locking portions along the longitudinal direction thereof, so that any one of them is selected and formed on the extension portion of the main body portion. By locking with the locking receiving portion, it is possible to adapt to pipe bodies having different pipe diameters.
Then, after holding the tube body by the band member and locking the locking portion to the locking receiving portion of the main body portion, the female screw member provided on the top portion of the main body portion is rotated to turn it into the screw rod.

The screw portion does not rotate like the first invention. The female screw portion may be, for example, a nut-like member welded to the through hole of the top portion, or may be formed by directly forming a female screw hole in the top portion.
Some of the long threaded rods to which the hanging brackets are attached are of a type that rotates themselves. In this case, the threaded rod side is not rotated, but the threaded rod side is rotated. This is because the tip of the screw rod can be brought into contact with the pipe.
Accordingly, in the second embodiment of the present invention, a female screw portion is formed directly on the top portion of the main body portion to provide the same functions and effects as those of the first invention.

In the third one of the present invention, in addition to the above effect, by forming a gripping portion at the end that is the free end of the band member, the gripping portion is gripped with a finger of a hand, etc. When deforming along the outer shape of the tubular body, it is very easy to deform and becomes convenient.
Further, when the locking portion of the band member and the locking receiving portion of the main body portion are locked, the gripping portion can be held and easily locked.

In the fourth aspect of the present invention, the main body and the band member are formed separately, that is, even if one end of the band member is not fixed to one side edge of the main body. The present invention can be implemented.
As a result, a plurality of sizes of the main body part and the band member, which are constituent members, are separately manufactured, and an appropriate one is selected from several types of band members having different lengths according to the pipe diameter of the pipe to be fixed. By selecting or appropriately selecting the main body portions having different sizes, it becomes possible to cope with more types of tube bodies having different tube diameters.

DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of a pipe hanging bracket according to the present invention will be described with reference to the accompanying drawings.
1 is a perspective view illustrating an embodiment of the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a right side view thereof.
A piping hanging bracket 10 according to the present invention includes a main body 11 and a band member 20.

  The main body 11 and the band member 20 are both made of metal, but the band member 20 is made of a thin plate-like body that can be plastically deformed, and has a long hole 25 in the longitudinal direction of the substantially central portion thereof. This long hole is for facilitating the deformation of the band member 20. However, this long hole 25 can be implemented without being provided, and is optional.

The main body 11 includes a top portion 12 and extension portions 14 and 16 extending substantially downward from both side edge portions of the top portion 12 and has a substantially U shape.
A through hole is formed in a substantially central portion of the top portion 12, and a female screw member 15 having a form like a hexagonal nut is provided in the through hole portion. The female screw member 15 is pivoted to the top portion 12. It is provided freely.

One end 21 of the band member 20 is fixed to one extension 14 of the main body 11. A grip portion 23 is provided at the other end portion 22 which is a free end of the band member 20.
This grip part 23 is the structure which just bent the other end part 22 of the band member 20 at the substantially right angle in the outer side direction.

The other extension 16 of the main body 11 is provided with two locking receiving portions 17 and 17, and the locking portions 27 and 27 are provided at the positions of the band members 20 corresponding to the locking receiving portions 17 and 17. Provided.
In this embodiment, two locking portions 27, 27 are provided in a direction substantially perpendicular to the longitudinal direction, and two rows of these locking portions 27, 27 are provided in the longitudinal direction.
These locking portions 27 are formed from holes, and the locking receiving portions 17 locked to the hole portions are formed from protrusions. That is, both can be locked by fitting the hole into this protrusion.

Further, as can be seen from the figure, the shape of the hole serving as the locking portion 27 is such that the lower portion is formed into a large circle and the upper portion is formed into a long and narrow rectangle.
This is designed in such a shape in order to make it easier to fit the locking part 27 into the locking receiving part 17.
The grip part 23 can be gripped with the fingers of the hand at the festival of locking the locking part 27 and the locking receiving part 17 to each other.

The procedure for attaching the tube is as follows.
First, the female screw member 15 provided on the top portion 12 of the main body portion 11 is screwed from the lower end portion of a screw rod (not shown) suspended from the top portion or the like of the building structure. The main body 12 is screwed to the extent that it slightly protrudes from the lower surface.
The grip portion 23 at the end of the band member 20 is gripped with fingers of the hand, and the band member 20 is wound along the outer peripheral surface of the tubular body (not shown), and the engagement formed on the end portion 22 of the band member 20 The stop portions 27 and 27 are locked to the lock receiving portions 17 and 17 of the main body portion 11.

As described above, the latch receiving portion 17 is formed of a protruding portion, and the locking portion 27 is formed of a hole portion. Therefore, the hole portion may be fitted into the protruding portion.
In this state, when the female screw member 15 is further screwed into the screw rod, the tip portion of the screw rod comes into contact with and presses the outer surface of the tube body.
As a result, the tubular body is suspended and fixed by the piping hanging bracket according to the present invention.

FIG. 4 shows this suspended and fixed state.
FIG. 4 is an explanatory front view of a state in which the tubular body is fixed.
The tube body 40 is surrounded by the band member 20 and is pressed and fixed to the upper portion of the tube body 40 to which the lower end portion 31 of the screw rod 30 is fixed.

The procedure for fixing has been described above. As can be seen from this figure, the tube body 40 to be suspended and fixed has a different outer diameter, for example, larger than can be fixed in the state shown by the phantom line. An outer diameter tubular body can also be fixed by the same-sized suspension fitting according to the present invention.
The reason why the pipe bodies having different outer diameters can be fixed is as described above by selecting one of the rows of the locking portions formed side by side in the longitudinal direction at one end of the band member 20, This is realized by the engagement distance of the female screw member 15 to the screw rod 30 by being engaged with the engagement receiving portion 17 of the main body portion 11.
As described above, in the present invention, pipes having different pipe diameters can be connected to the same suspension metal fitting by cooperating with the pressing of the tip 31 of the screw rod 30 by screwing the female screw member 15 and the length adjustment of the band member 20. It can be fixed with.

Although the embodiment of the present invention has been described above, the design can be changed as follows in the present invention.
First, in the above embodiment, a rotatable female screw member is provided on the top of the main body, but instead of this rotatable female screw member, a female screw is formed directly on the ceiling. It can also be implemented.

There are some long threaded rods to which this type of hanging bracket is attached, in which the threaded rod can be rotated. In this case, the threaded rod can be rotated by rotating the threaded rod side. It is because the front-end | tip part of this can be made to contact | abut to piping.
When forming the female screw part at the substantially central part of the top part, it is desirable to perform a burring process or the like so as to make the length in the longitudinal direction where the female screw part is engraved longer.
Alternatively, a nut may be welded to the hole at the substantially central portion of the top portion.

The shape and size of the main body can be set as appropriate.
In the above embodiment, the extension portion is formed on both side edges of the top portion of the main body portion. However, the extension portion is not necessarily provided on the side to which the band member is fixed, and the band member is not directly provided on one side of the top portion. It can be carried out without fixing to the side edge and forming an extension.

One side for fixing the band member is formed separately from the main body, and is not fixed in advance, but may be configured to be detachable.
In this case, it is preferable to form extension portions extending downward from the side edge portion of the main body portion on both sides of the side edge portion.
By providing this extension on both sides, a hole is formed in the band member to form a locking portion, similar to the end where the gripping portion of the band member is formed, and the extension on the other side of the main body. A protrusion may be formed as the locking receiving portion, and both can be coupled by locking both.

The configuration of the locking portion and the locking receiving portion is not limited to the combination of the hole portion and the protruding portion, and may be any configuration as long as both can be appropriately locked or engaged.
The length and width of the band member in the longitudinal direction can be freely designed and can be set as necessary.
The number of locking portions formed of holes provided in the band member is also arbitrary, and the number of longitudinal rows in which the locking portions are provided can also be freely designed.

Finally, the hanging metal fitting according to the present invention can fix not only a tube having a circular cross section but also a square tube, and not only a metal tube but also a tube other than a metal tube such as a cooler tube. Can also be fixed.
Furthermore, a plurality of pipes can be fixed simultaneously, and a plurality of cables and the like can also be fixed.

In addition to being suspended, the screw rod can be extended in the horizontal direction or from the bottom to the top and fixed to the tip.
Moreover, in the festival to construct, it can also carry out by inserting a cap in the front-end | tip part of the screw rod which contacts and presses piping. As this cap, a cap made of rubber, synthetic resin or the like can be used, and the cap can be configured so as not to rotate its contact surface.
As described above, the present invention has been able to provide an apparatus that exhibits a very large effect with a simple configuration and that can fix pipe bodies having different pipe diameters with the same suspension fitting.
