  The technique shown in Patent Document 1 has a configuration in which a plurality of pipes are held and supported by a U bolt on a long support member.

  However, this technique has a drawback that the holding stability is low because of the line contact support by the U bolt.

  The technique shown in Patent Document 2 has a configuration in which a plurality of pipes are held and supported by a pipe band fixed on a long support member.

  However, in this technique, the holding stability is high because it is a surface contact support by the piping band as compared with the line contact support by the U bolt shown in Patent Document 1, but the support is because the piping band is fixed to the support member. Since the position adjustment in the longitudinal direction of the member and the angle adjustment in the piping direction are impossible, there is a drawback that it is difficult to cope with construction errors such as pipe pitch deviation and pipe angle deviation.

  The technique shown in Patent Document 3 has a configuration in which a plurality of pipes are held and supported on a long support member by a pipe band attached so that the movement of the support member in the longitudinal direction can be adjusted.

  However, with this technology, it is possible to adjust the pipe support position in the longitudinal direction of the support member, but the angle of the pipe band attached to the support member cannot be adjusted, so it corresponds to the pipe angle deviation in the pipe direction. It has the disadvantage of being difficult to do.

  The technique shown in Patent Document 4 has a configuration in which a plurality of pipes are held and supported on a long support member by a pipe band attached to a slider member that can slide in the longitudinal direction of the support member.

  However, with this technology, it is possible to cope with the pipe support position in the longitudinal direction of the support member and the pipe angle deviation in the pipe direction, but the support member may be distorted, bent, bent, etc. due to the influence of the mounting surface at the construction site. When it occurs or when it adheres to a support member such as dust at the construction site, the slide of the slider member fitted in an idle state with respect to the support member having an L-shaped cross section is not smooth or difficult to slide. However, there is a drawback that it is difficult to adjust the position in the field, and the workability is likely to deteriorate.

A multiple piping support 1 according to the present invention includes a long pedestal 2 fixed to a mounting surface such as a floor or a ceiling, a pair of column bolts 3 and 3 standing on the pedestal 2, and the pair of columns. A long support member 4 installed between the bolts 3 and 3, and three pipe bands 5A, 5B, and 5C that are movable in the longitudinal direction of the support member 4 and attached in parallel. The main structure. In addition, although a present Example demonstrates the aspect which is three piping of a parallel state, the number of piping supported by the support tool for multiple piping of this invention is not restricted to three, Even if it is two It may be four or more. In FIG. 1, reference numeral 6 is a nut for fixing the support bolts 3, 3 to the base 2, and reference numerals 7, 8 are nuts for fixing the support member 4 to the support bolts 3, 3.

  The support member 4 is formed of a plate material having an L-shaped cross section as shown in FIG. Moreover, it is preferable that the support member 4 has a minimum height of the pipe height from the mounting surface when the construction is such that the lowest limit position of the pipe to be connected, such as a drain header. In order to regulate the minimum height, it is preferable to interpose a spacer as a nut 13 between the nut 6 on the base 2 and the nut 8 on the lower surface of the support member 4 as shown in FIG. That is, the total thickness of the three nuts 6, 7, and 13 can be regulated by setting the minimum height of the pipe height (approximately 30 mm in the case of a general drainage header). The spacer may be a tube that can be inserted into the support bolt 3 instead of the nut 13 that is screwed to the support bolt 3, or a plate material that can be clamped, fixed, or attached to the support bolt 3. Other members may be used.

  Further, the support member 4 has through holes 9A, 9B, and 9C formed in the longitudinal direction as shown in FIG. The through holes 9A, 9B and 9C are elongated holes extending in the longitudinal direction of the support member 4, and at least the number of the piping bands 5A, 5B and 5C attached to the support member 4 (three in this embodiment). The number of the long holes corresponding to the number (3 or more, 3 in this embodiment) is formed.

  In the through holes 9A, 9B, and 9C, band fixing bolts 10, 10, and 10 for fixing the plurality of piping bands 5A, 5B, and 5C to the support member 4 are provided from the pedestal side 2 of the support member 4, respectively. It is inserted toward the side opposite to the base 2.

  Further, each of the band fixing bolts 10, 10, 10 is inserted in the through holes 9 A, 9 B, 9 C, and is prevented from falling off with respect to the support member 4, and is associated with the nut screwing. It is fixed in a state that prevents As a means for preventing the band fixing bolts 10, 10, 10 from falling off and preventing accompanying rotation, for example, a preventer 11 as shown in FIG. Can be used. As shown in FIG. 5, the preventer 11 is formed of a plate-like material having a U-shape when viewed from the side, and the support member 4 is sandwiched between the two plates 11A and 11B. The notch 11C formed in 11A enters the thread groove of the band fixing bolt 10 to prevent the falling from the support member 4, and the restricting part 11D formed in the plate 11B prevents the bolt head of the band fixing bolt 10 from rotating. By restricting the nut 11, it is possible to prevent accompanying rotation when the nut 11 is screwed or tightened.

  The pipe bands 5A, 5B, 5C attached to the support member 4 by the band fixing bolts 10, 10, 10 are cantilevered with a bolt insertion hole through which the band fixing bolts 10, 10, 10 are inserted at one end of a substantially U shape. A band of the type. The band fixing bolts 10, 10, 10 can be fixed by screwing and tightening nuts 12, 12, 12 to the band fixing bolts 10, 10, 10 with the piping held and supported.

  With the above configuration, each of the piping bands 5A, 5B, and 5C for holding and supporting the piping is attached to the support member 4 by the band fixing bolts 10, 10, and 10 inserted into the long holes 9A, 9B, and 9C. By being attached, it is possible to adjust the movement of the support member 4 in the longitudinal direction, so that it is possible to cope with various piping pitches, pitch deviations, and the like. In addition, the pipe bands 5A, 5B, and 5C are cantilevered bands, and one end of the band is attached to the support member 4, so that the pipe angle can be shifted or slanted by rotating around the one end. It can also handle piping.

  Furthermore, since the band fixing bolts 10, 10 and 10 are inserted into the support member 4 in a state of preventing the drop off, in order to open the pipe bands 5A, 5B and 5C when holding the pipe. Even if the nuts 12, 12, 12 are removed, the band fixing bolts 10, 10, 10 do not fall out, so that not only can they be lost on complicated sites, but also workability can be prevented from being lowered. it can. Furthermore, since the nut 12 is inserted in a state of preventing the nut 12 from being screwed, the nut 12 can be easily and smoothly screwed without pressing the bolt heads of the band fixing bolts 10, 10, and 10. So workability is high.

  As mentioned above, although one Example of the support tool for multiple piping which concerns on this invention was described, this invention is not limited above, For example, the following aspect can also be taken.

In this case, for example, as shown in FIG. 5, two of the three through holes 9A, 9B, and 9C formed in the support member 4 (9B and 9C) have the same orientation, and one (9A) is formed. The through-holes 9B and 9C are formed in different directions from the support member 4 used in the above-described embodiment shown in FIG.

  By placing two of the three piping bands 5A, 5B, and 5C (5B and 5C) in the same direction and one (5A) in a different direction, as shown in FIG. Even when the pipe pitch of the pipes 14A, 14B, and 14C is narrow, the holding member 4 can be held and supported by arranging the support member 4 in an inclined state with respect to the pipes P, P, and P. In particular, the interference between the band ends of the adjacent piping bands 5A, 5B and 5C and the band fixing bolts 10 and nuts 12 and the pipes P, P and P can be reduced. Since the screwing tool can be used without receiving interference from the other end of the pipe band (one of 5A, 5B, and 5C) adjacent to the pipe band, the flexibility of the pipe support is high and the workability is high.

  Further, the through holes 9A, 9B, and 9C, which are long holes formed in the support member 4, are not limited to the modes shown in FIGS. 3 and 5, and as shown in FIG. 7, there are three through holes 9A and 9B. -The direction of the piping band 5B attached to the center through hole 9B by making the long diameter of one middle (9B) of 9C longer than the long diameter of two (9A, 9C) on both sides (9A, 9C) Can be made the same as that of the piping band 5A, or can be made the same as the piping band 5C, so that it can be appropriately changed to correspond to the piping pitch or the like of the construction site. When the number of the through holes formed in the support member 4 is not three but four or more, for example, two in the case of four, three in the case of five, both sides What is necessary is just to form the long diameter of the long hole except two in this to be longer than the long diameter of the long hole of the both sides.

  Further, the through holes 9A, 9B, and 9C, which are long holes formed in the support member 4, are formed as a through hole 9D which is one long hole extending in the longitudinal direction of the support member 4, as shown in FIG. You can also. In this case, since the direction of each of the piping bands 5A, 5B, and 5C attached to the through hole 9D can be changed, the three pieces are made the same direction, the two pieces are made the same direction, and the one pieces are made different directions. You can also. When two are in the same orientation and one is in a different orientation, (1) 5A and 5B are in the same orientation and 5C are in different orientations, (2) 5A and 5C are in the same orientation and 5B are in different orientations (3) 5B and 5C may be in the same direction, and 5A may be in a different direction. Further, the number of piping bands to be attached is not limited to three, and may be two or four or more.

  Furthermore, the support member 4 is not limited to a plate member having an L-shaped cross section as shown in FIG. 2, and may be a U-shaped cross-sectional material or a rod-shaped body having a rectangular cross section as shown in FIG. In the case of the rod-shaped body shown in FIG. 9, the long hole can be formed as a slit 9 </ b> E that penetrates both ends of the support member 4 in the longitudinal direction.
