[0002]

2. Description of the Related Art A flexible polybutene pipe or the like is used for an air-conditioning pipe in which an outgoing pipe and a return pipe are arranged in parallel and a water supply / hot-water pipe arranged in a pair. The suspension fittings for suspending must be arranged at a short pitch. For this reason, the labor required for suspending work such as insert punching and mounting of suspension bolts performed near the ceiling has been enormous.

[0003] The spacing between pipes requiring heat insulation must be kept constant so as not to be too close. In addition, in order to keep the spacing from the ceiling constant, complicated and expensive turnbuckles must be used. I had to. In addition, if one pipe is hung at a time, a large number of pipes may be in an upset state, and it is particularly difficult to distinguish between the outgoing pipe and the return pipe which should be paired during maintenance. There was a problem that it is.

Japanese Unexamined Patent Publication No. 5-99372 discloses a metal fitting for hanging pipes one by one. However, it is difficult to attach such metal fittings at a short pitch. It will take effort. JP 4

SUMMARY OF THE INVENTION It is an object of the present invention to provide a pair of piping such as an air-conditioning pipe in which an outgoing pipe and a return pipe are arranged in parallel, and a pipe for hot and cold water supply arranged in pairs. The present invention is to provide a pipe suspension device suitable for suspending a pipe at the same time. It is another object of the present invention to provide a pipe hanging apparatus capable of adjusting a distance between a pipe and a ceiling without requiring a turnbuckle.

It is still another object of the present invention to provide a pipe hanging apparatus capable of adjusting a distance between pipes. Still another object of the present invention is to provide a pipe suspension device for making a pair of pipes of the same system easily identifiable from pipes of another system.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a rod member having a mounting portion for a ceiling-side frame at an upper portion and a male screw portion at a lower portion thereof, and a male screw of the rod member. A U-shaped bracket having a plate portion having a hole for receiving the portion at the center and tab portions extending downward from the left and right sides of the plate portion, and a ring-shaped holding bracket for gripping the pipe by bolting, In each tab portion of the bracket, a horizontal insertion groove for inserting the bolt of the holding bracket in a direction perpendicular to the axis thereof and a vertical mooring groove for guiding and stopping the inserted bolt vertically downward are formed in series. The present invention provides a pipe suspension apparatus characterized in that a holding fixture is held in a mooring groove by a fastening force of a bolt and gravity.

[0008]

In order to use the suspending device of the present invention based on such a structure, first, the rod member and the bracket are bolted to each other.
After connecting with a nut, the upper mounting portion (hook, male screw, etc.) of the rod member is hooked into a hole in the ceiling frame, or a male screw is screwed into a screw hole that has been inserted.

Next, a pair of ring-shaped holding fittings (tightening bands) are wound around pipes, respectively, and the tightening bolts at the upper portions thereof are moved halfway while being moved in a direction perpendicular to the axis of the bolts. Then, insert the bracket into the horizontal insertion groove of the tab. The inserted bolt falls so as to be guided by the groove, enters the vertical mooring groove from the horizontal insertion groove, and is stopped.

Here, if the pipes are fixed by tightening the bolts of the holding fittings, the holding fittings are held in the mooring grooves by the tightening force of the bolts and gravity, and are held so as not to fall off even by vibration due to an earthquake. Will be.

[0011] If the pipe suspension apparatus of the present invention is used, 2
The book pipes are hung by one metal fitting while maintaining the necessary intervals, and the number of work steps is reduced by half. Further, since the bolts of the ring-shaped holding metal fittings for fastening the respective pipes may be inserted into the grooves of the tabs of the bracket in a state where they are partially tightened, the work efficiency is significantly improved.

To adjust the distance between the pipe and the ceiling,
Since the tightening position of the nut in the male screw portion of the rod member may be adjusted up and down, it is not necessary to use a complicated and expensive turnbuckle as in the related art, resulting in a significant cost reduction. In addition, since a pair of pipes are suspended by one suspension bolt, even if a large number of pipes are arranged in parallel, the pipes of the same system can be easily identified and maintenance becomes easy.

Further, when it is desired to adjust the interval between the pipes, a desired interval can be conveniently obtained by bending the plate portion of the placket. Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 shows a pipe suspension apparatus 10 according to a preferred embodiment of the present invention. The apparatus 10 comprises a rod member 12, a U-shaped bracket 14, and a pair of pipes 6.
And a pair of ring-shaped holding fittings 16 for holding the first and second bolts 62 with bolts. In the illustrated example, the rod member 12 has a hook formed at an upper portion as an attachment portion 21 to the ceiling-side frame 50, and the hook is hooked in the groove 52 of the ceiling frame and held as it is or caulked by an external force. Fixed. A male screw portion 22 is provided at the lower portion of the rod member 12, and nuts 23 and 24 are made to mesh with the male screw portion 22.

The bracket 14 includes a plate portion 32 having a hole 31 at the center for receiving the male screw portion 22 of the rod member 12, and tab portions 34 extending downward from the left and right sides of the plate portion 32, respectively. Made in. As an example of the dimensions of the bracket 14, the width of the plate portion is 32 mm and the length is 110 m.
m and the length of the tab portion can be set to 50 mm.

The holding bracket 16 may be in the form of a band which is widely commercially available, and may be a metal or plastic ring 4.

And a vertical mooring groove 36 for guiding the inserted bolt vertically downward and stopping it.

Thus, the holding fitting 41 is firmly held in the anchoring groove 36 of the tab portion 34 by the tightening force of the bolt and nut and the gravity. When it is desired to adjust the interval between the pipes, a desired interval can be obtained by bending the plate portion 32 of the placket 14.

The frame 50 on the ceiling side of the rod member 12
Is not limited to the hook shape as shown in the figure, but in a construction method in which an insert having a female screw cut inside is embedded in the ceiling, the mounting portion 21
1 may be a male screw part.

The hole 31 for receiving the male thread portion 22 of the rod member 12 in the bracket 14 has a through hole slightly larger than the bolt diameter in the illustrated example, but as a modified example, the plate thickness of the bracket 14 is increased to increase the hole thickness. An internal thread may be cut in the interior of 31. In this case, since the male screw 22 meshes with the female screw, the nut 24 can be omitted.

The pipe suspension device of the present invention is a
It is suitable for suspending a pair of pipes, but it is also convenient for suspending pipes of another system one by one, and is also used for suspending only one pipe without using one side. be able to.
