DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of the present invention will be described with reference to FIGS.

First, the configuration of this embodiment will be described in detail.

This embodiment has a structure in which a lower portion of a mounting member 3 provided with a screw portion 2 for screwing to a suspension bolt 1 on an upper portion and a lower portion of a pair of holding halves 4A are pivotally connected to be freely openable and closable. The upper portion of the pipe holding member 4 is overlapped, and through holes 5 are formed in communication with the overlapping portion of the mounting member 3 and the pipe holding member 4, and the fastening bolt 6 is inserted through the through hole 5. Then, in a pipe support fitting to which a nut is screwed and connected as a fastener 8,
One of the through holes 5 is formed into a tapped screw hole 5A, and a small diameter screwless screw is located at a base end of the fastening bolt 6 and inserted into the screw hole 5A at the time of the tightening connection. The present invention relates to a piping support fitting provided with a portion 7.

It is sufficient that the diameter of the small screwless portion 7 is smaller than the diameter of the screw thread portion of the fastening bolt 6, but it is better to make the screwless portion 7 thinner as shown in the figure. And the screw hole 5A is widened, and the fastening bolt 6 is easily inclined downward.

In this embodiment, the screw hole 5A is provided at the base end side of the fixing bolt 6 of the mounting member 3. However, the screw hole 5A is provided.
The through-hole 5 forming the hole need not be at one place, and the operation and effect of the present invention can be obtained even at a position where the through-hole 5 contacts the tip end of the fastening bolt 6.

However, if the screw hole 5A is provided at a position corresponding to the distal end side of the fixing bolt 6, the small diameter threadless portion 7 of the fixing bolt 6 can be provided only at the distal end side of the fixing bolt 6 or at the proximal end from the distal end side. If it is not provided in a wide range toward the side, the function and effect of the present invention will not be exhibited, and such a fastening bolt 6 is troublesome to manufacture, and may increase the cost of the pipe support fitting. In addition, when the fastening bolt 6 is tilted to rotate the holding half 4A, the fastening bolt 6 is tilted about the through hole 5 at the base end side of the fastening bolt 6 as a fulcrum. Hole 5
When A is provided, the diameter of the threadless portion 7 must be made very small. Therefore, it is better to provide the screw hole 5A at a position corresponding to the base end side of the fastening bolt 6 as in this embodiment.

Next, the method of use of the present embodiment will be described in detail including the effects.

In the pipe support, the mounting member 3 and the pipe holding member 4 are connected in advance by the fastening bolts 6 and the fasteners 8.

FIG. 2 shows a method of connecting the mounting member 3 and the pipe holding member 4. The turning of the fastening bolt 6 causes the fastening bolt 6 to be inserted into the screw hole 5 A and the through hole 5.
And the tightening tool 8 is rotationally tightened.

This pipe support is fixed by screwing the screwing portion 2 to the suspension bolt 1.

Then, in order to fix the pipe 9 to the pipe support, the fastener 8 is first turned and removed.

At this time, the through hole 5 is configured to be larger than the diameter of the screw thread of the fastening bolt 6, and the fastening bolt 6 is provided with a small-diameter non-threaded portion 7. 7 is smaller than the inner diameter of the screw hole 5A, and there is a gap between the threadless portion 7 and the screw hole 5A, so that the fastening bolt 6 can be tilted downward.
Then, the holding half 4A on the side of the fastener 8 can be rotated downward to be removed, and the upper part on one side of the pipe holding member 4 can be opened.

Then, holding the pipe 9 by hand, the fixing bolt 6
Temporarily hold the holding half body 4A on the base end side, and fix the fixing bolt 6 again.
Is tilted downward, the holding half 4A that has been turned downward is turned upward to communicate with the fastening bolt 6, and the holding half 4A is overlapped with the mounting member 3 so as to sandwich the pipe 9, The pipe 9 is fixed by attaching the fastener 8 to the fastening bolt 6 and rotating and tightening it.

At this time, the thread of the fixing bolt 6 is caught by the thread of the screw hole 5A, so that the fixing bolt 6 does not fall out of the pipe support during a series of operations.

That is, since the present embodiment is constructed as described above, the fastening bolt 6 does not fall out of the pipe support fitting, so that the pipe holding member 4 does not fall out of the pipe support fitting. It becomes a pipe support fitting excellent in practicality by spoiling the conventional characteristics of the fitting.

[0031]

As described above, according to the present invention, at least one of the through holes is formed in the screw hole by forming a tap or attaching a nut, so that the fastening bolt is dropped from the through hole unless the fastening bolt is rotated. Therefore, since the fastening bolt does not come out of the through hole, the connection between the mounting member and the pipe holding member does not come off, that is, the pipe holding member does not drop. Since a small diameter screwless portion is provided at a position where it is inserted into the screw hole when the fastening bolt and the fastener are tightened and connected, there is a gap between the screw hole and the screwless portion of the fastening bolt. It is possible to tilt the fixing bolt downward when removing the holding half on the fastener side from the fixing bolt as before, and it is an epoch-making with excellent practicality such as the characteristics of the pipe support bracket are not impaired It becomes a typical piping support fitting.
