Description

[Detailed description of the invention] <<Industrial Application Field>> This invention relates to a pipe support fitting that supports piping in a building.

《Prior technology》 A conventional pipe receiving fitting will be explained with reference to FIG.

This metal fitting consists of a main hanging metal fitting 2 fixed to the lower end of the hanging bolt 1, and a pair of sub-hanging metal fittings that are jointly fastened to the lower part of the main hanging metal fitting 2 by a pair of bolts 3 and nuts 4 and that expand in the downward direction. 5, and a tube support roller 6 whose both ends are rotatably supported at the lower part of each sub-hanging metal fitting 5. The pipe P for piping is held in a loop formed by each sub-hanging fitting 5 and the pipe support roller 6.

<<Problems to be solved by the invention>> In this structure, when the pipe P is inserted directly into the loop, the main hanging fitting 2 and the sub-hanging fitting 5 may be assembled in advance. However, in reality, due to the length of the pipe P, the loop is often opened and inserted into the loop from the side. In this case, remove the nut 4, leave the load of the pipe P on the roller 6 with one of the sub-hanging fittings 5 open, and then rotate the one of the sub-hanging fittings 5 to close the loop and tighten the nut. Assembly must be done by tightening 4. Moreover, this work had to be performed at a high place, and a large number of parts were to be installed, which required a great deal of effort. Furthermore, since there are a large number of pipes to be installed, it is possible to forget to tighten the nuts 4, which may cause the pipes to loosen due to vibrations, which may lead to accidents.

Therefore, for example, Japanese Utility Model Application Publication No. 59-174475 proposes a pipe receiving fitting to solve this problem.

However, the fitting shown in this publication consists of a pair of semicircular rings connected by a hinge and pivoted to the hanger unit, so when installing the piping, it is necessary to support the piping with one hand. However, the ring of the metal fitting must be attached to the outer periphery of the pipe using the other hand, and both hands of the operator are required to attach the pipe, resulting in poor workability.

This idea was devised in view of the above-mentioned problems, and it is possible to close the loop with a single touch, securely locking the closed end, and provide a pipe holder with high work efficiency that allows the worker to attach the pipe with one hand. The purpose is to provide.

<Means for Solving the Problems> In order to achieve the above object, the present invention includes a hanger-shaped main suspension member whose upper end is integrated with a suspension bolt and whose lower end rotatably supports one end of a tube support roller. , a sub-hanging member rotatably supported on the other end of the tube support roller; a stabilizing pin provided on the rotating end side of the sub-hanging member; and a stabilizing pin provided in the main suspending member; It consists of a pin insertion hole to be fitted, and a latch pivotably supported in the middle of the main hanging member so as to be pivotable in the vertical direction, and the rotating end of the sub-hanging member is arranged on the side surface of the middle part of the main hanging member. The latch is rotated downward in a state where the stabilizing pin and the pin insertion hole are fitted, and the latch tightens the rotating end of the sub-hanging member.

<<Operation>> According to the pipe support fitting having the above configuration, the pipe support roller is pivotally supported by the hanger-shaped main hanging member, and
Since the sub-hanging member is rotatably supported at one end of the pipe support roller, when the sub-hanging member is rotated, there is a large gap on the side, allowing the operator to place the pipe on the support roller with one hand. You can also
If you insert the stabilizing pin into the pin insertion hole and temporarily secure it,
Horizontal slippage is prevented, the temporarily fastened state is stable, and
Quite heavy piping can be supported in this state, and when the latch is rotated downward, the latch will not come off due to earthquakes or vibrations, and furthermore,
Even if the piping moves in the axial direction, it can be stably supported.

<<Example>> Hereinafter, an example of this invention will be described in detail using the drawings.

In the figure, 10 is a main hanging fitting obtained by bending a flat steel material, 12 is a tube support roller whose one end is rotatably supported on the lower end of the main hanging fitting 10, and 1
Reference numeral 4 designates a sub-hanging metal fitting pivotally supported at the other end of the tube support roller so as to be rotatable along the side surface of the pipe P as shown by arrow A.

The main hanging fitting 10 is constructed by overlapping an intermediate part 10b on the lower part of a main hanging part 10a formed of a flat steel material with a rectangular cross section, and integrating the parts by spot welding.
Hanging piece 1 with the lower part of b expanded downward
It is like a hanger formed by extending 0c. A hanging bolt 16 is attached to the upper part of the main hanging part 10a.
A pair of bracket portions 18 are formed upright on the intermediate portion 10b, and the bracket portions 18
A substantially U-shaped latch 2 is inserted through the center pin 20.
2 is pivoted so that it can move up and down as shown by arrow B.

The tube support roller 12 is drum-shaped,
The shaft portions 12a at both ends thereof are attached to the lower ends of the hanging piece 10c and the sub-hanging fitting 14 by caulking.

The sub-hanging metal fitting 14 is curved line-symmetrically with the hanging piece 10c, and a bent piece 14a is formed on the upper part thereof along the intermediate portion 10b. Further, a stabilizing pin 26 is welded to the secondary hanging fitting 14 so as to have a protrusion at the shoulder of the intermediate portion 10b, which is the contact area between the secondary hanging fitting 14 and the main hanging fitting 10, and a pin insertion hole is provided at the opposite position. 24b is formed so that the protrusion of the stabilizing pin 26 can be fitted into the insertion hole 24b.

To insert the pipe P into the pipe receiving fitting configured as above, with the latch 22 positioned upward,
If the sub-hanging metal fitting 14 is tilted forward or backward using the shaft portion 12a of the roller 12 as a base point, the roller 1
2, the hanging piece 10c, and the sub-hanging metal fitting 14, one side of the loop is wide open, and the pipe P can be inserted into the loop from here with one hand. Next, rotate the sub-hanging fitting 14 to attach the upper bent piece 14.
a to the intermediate portion 10b, and fit the protrusion of the stabilizing pin 26 into the insertion hole 24b to temporarily fix the pipe P. In this state, both ends of the pipe support roller 12 are supported by the main and sub-hanging fittings 10 and 14, so even the pipe P, which has a certain amount of weight, can be stably supported while preventing lateral displacement. Furthermore, the latch 22 is rotated downward to surround the upper part of the sub-hanging bracket 14, and then the protruding end of the sub-hanging bracket 14 from the latch 22 is bent and crimped in the direction of arrow C as shown by the solid line in FIG. By attaching the secondary hanging bracket 14
The pivot end will be completely locked, closing the loop.

According to this embodiment, a triple lock structure is achieved by the pin 26, the latch 22, and the crimping operation,
It becomes completely fixed.

<<Effects of the invention>> Since this invention is constructed as described above, it can be easily assembled without the troublesome assembly work or forgetting to tighten bolts and nuts as in the conventional art. Additionally, since the piping can be installed with one hand, work efficiency is greatly improved, contributing to shorter construction times and improved quality control.
