Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a piping upright band, and more particularly to a piping upstanding band that prevents a bolt inserted into and screwed into a piping upright band from falling off.
[0002]
[Prior art]
A conventional standing band has a T-shape in which a pipe is held by a pair of band portions integrated by a hinge mechanism or a combination mechanism, and ends of both band portions are fixed to a wall surface or a floor by bolts and nuts. It was the structure which supports piping in the holding state by fixing to this support member. The bolts and nuts used for fixing are one set in the suspension band, but in the case of the standing band, two sets are used to prevent the rotation of the band.
[0003]
When installing, once remove the nut screwed to the bolt, open one side of the band part of the standing band and pass the pipe inside, then return the one side of the band part to its original position and nut Tighten.
[0004]
At the time of this installation, the bolt hole prepared at the end of the support member and the band part is a so-called fool hole, so when removing the nut at the stage of holding the pipe and opening the band part on one side, Bolts often dropped out. In particular, in the case of the standing band, since there are two sets of bolts and nuts, the dropout frequency was higher than that of the hanging band.
[0005]
Therefore, the present inventor temporarily fixes each of the two bolts inserted into the end portion of the band portion on one side with two clips in Japanese Patent Application No. 8-317144 (Japanese Patent Laid-Open No. 9-317949). We proposed a technology that prevented the dropout.
[0006]
In addition, when the nut is screwed into the bolt and tightened after holding the pipe, the bolt also rotates along with the screwing of the nut. As a technique for solving such a problem, the present inventor disclosed in Japanese Patent Application Nos. 11-220906 (Japanese Patent Laid-Open No. 2001-50426) and 11-317748 (Japanese Patent Laid-Open No. 2001-141117). We have proposed a technology with excellent work efficiency that allows the nuts to be screwed together without the bolts being pressed with fingers by preventing the rotation of the bolts.
[0007]
As a result of further intensive studies on these techniques, the present inventor has found that there is room for further improvement in terms of work efficiency.
[0008]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION An object of the present invention is to provide a standing band type pipe standing band having a bolt drop-off preventing structure and a bolt follow-up preventing structure with improved work efficiency.
[0009]
[Means for Solving the Problems]
The above object of the present invention is achieved by the following configurations.
[0010]
1. The nut 4 is attached to the support member 2 fixed to the wall surface W , the floor, or the like with the bolt and the nut 4 and the nut 4 can be screwed in a state in which the bolt is prevented from being swung without being pressed with fingers. In the standing band 1 for piping supported as if the piping P is held by the pair of band portions 11 integrated by the hinge mechanism 10 or the assembly mechanism,
The bolt is a U-shaped bolt 3 having screw portions at both ends, and the U-shaped bolt 3 is a square bolt, and the square bolt used as the U-shaped bolt 3 is one end of the pair of band portions 11. the U-shaped on only one leg 3A or 3B corner bolts used as a bolt 3 clip 5 is attached to prevent falling off from the end portion 12A of one of the band portion 11A the in inserted state in section 12A A vertical band for piping characterized in that it is configured.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a specific configuration of the present invention will be described.
FIG. 1 is a plan view showing an embodiment of a standing band for piping according to the present invention, FIG. 2 is an enlarged plan view of a clip, and FIGS. 3 to 5 are enlarged plan views showing other embodiments of the clip.
[0012]
As shown in FIG. 1, the pipe standing band 1 according to the present invention includes a pair of band portions 11 </ b> A and 11 </ b> B connected by a hinge mechanism 10 (which may be a hinge type, a combination type, or a lantern type). Piping by attaching the end portions 12A and 12B to a support leg 21 of a support member 2 called a so-called T-shaped leg fixed to a wall surface W (floor or the like) by means of a U-shaped bolt 3 and nuts 4 and 4 Supports P as if it is being held.
[0013]
One of the leg portions 3A and 3B of the U-shaped bolt 3 inserted into the bolt hole formed in the end portion 12A of the one band portion 11A (the leg portion 3A in this embodiment) is included in the vertical band 1 for piping. Only the clip 5 having the configuration described later is attached.
[0014]
By mounting the clip 5, the U-shaped bolt 3 does not fall off from the one end 12A of the band portion 11A even when the nuts 4 and 4 are removed during the mounting operation.
[0015]
In the present invention, instead of the two bolts that have been conventionally used, one U-shaped bolt 3 is used, so that the clip 5 is attached to each of the two bolts to prevent the bolt from falling off. On the other hand, the clip 5 is attached to only one of the two legs 3A and 3B of the U-shaped bolt 3 (the leg 3A in this embodiment) to prevent the U-shaped bolt 3 from falling off. Can be achieved. Therefore, even though both the clips 5 are one, the U-shaped bolt 3 is not likely to fall off even if both nuts 4 are removed, and one band portion 11B to the other band portion 11A once. , Both the leg portions 3A and 3B of the U-shaped bolt 3 can be passed through the two bolt insertion holes of the band end portion 12B, and the holding and attaching work efficiency of the pipe P is improved, and the clip 5 In addition to halving the number of devices used, the labor at the time of mounting the clip 5 is also halved, so that the cost and labor can be further reduced. A square bolt is used as the U-shaped bolt 3.
[0016]
Furthermore, in the present invention, the use of the U-shaped bolt 3 does not cause a problem of accompanying rotation when the nut 4 is screwed. This eliminates the need for an accompanying device that is a separate component as in the previously proposed technology, and therefore has the effect of reducing the number of parts, the labor required for attaching the accompanying device, and the cost.
[0017]
Hereinafter, the configuration of the clip 5 will be described with reference to FIG.
The clip 5 is formed of an elastic thin (for example, about 0.7 mm) iron wire, bent at the center portion to form the ring 5A, intersected 5B, and further curved at the extension portion U. An engaging portion 5C is formed to only one of the leg portions 3A and 3B of the square bolt used as the letter bolt 3 , and the remaining portion is crossed 5D, and then the extension portion 5E is formed. Elasticity is generated by the ring 5A and the intersection 5B, and the diameter of the engaging portion 5C can be increased by pressing the extension portion 5E in the sandwiching direction. If the extension portion 5E that has been pressed is released, the engaging portion 5C Is restored by elasticity, and only the legs 3A or 3B are sandwiched. Therefore, the clip 5 can be attached to the legs 3A or 3B ( 3A in this embodiment) only very easily.
[0018]
Further, since the iron wires are twisted at the intersection 5B and the intersection 5D, when the nut 4 is screwed onto the one leg 3A of the square bolt used as the U-shaped bolt 3, the washer is tightened. It functions in the same way as the nut 4 and prevents the nut 4 from loosening. Contrary to the above, it may be configured not to twist.
[0019]
The clip 5 described above can be formed of a thin iron wire, a metal wire such as a copper wire or an aluminum wire, or a synthetic resin material.
[0020]
3 to 5 show other embodiments of the clip 5. In the embodiment shown in FIG. 3, instead of the ring 5A of the clip 5 shown in FIG. 2, a triangle-like structure is provided with elasticity, and a bolt engaging portion 5C is formed at the center portion, and the U portion is extended from the extension portion 5E side. The engaging portion 5 </ b> C can be easily engaged with the leg portion 3 </ b> A simply by being pushed into one leg portion 3 </ b> A of a square bolt used as the letter-shaped bolt 3.
[0021]
The aspect shown in FIG. 4 is the same as the clip 5 shown in FIG. 2 in that the elasticity of the ring 5A is used, but has no crossing 5B and 5D. Similar to the embodiment shown in FIG. 3, a bolt engaging portion 5C is formed at the center, and the leg is simply pushed into the leg 3A of the square bolt used as the U-shaped bolt 3 from the side of the extension 5E. The engaging portion 5C can be engaged with the portion 3A.
[0022]
As described above, in the embodiment of the clip 5 described with reference to FIGS. 2 to 4, the groove is annularly formed on the leg 3 </ b> A / 3 </ b> B side of the square bolt used as the U-shaped bolt 3 in order to make the mounting position of the clip 5 accurate. It may be provided.
[0023]
In the embodiment shown in FIG. 5, the clip 5 is formed in a substantially R shape, and the straight portion is inserted into the pin holes provided in the leg portions 3 </ b> A and 3 </ b> B of the square bolt used as the U-shaped bolt 3. Is used to prevent a drop from the square bolt used as the U-shaped bolt 3 held in the bolt engaging portion 5C. If the extension portion 5E is pulled away from the straight portion, it can be removed from either one of the leg portions 3A and 3B of the square bolt used as the U-shaped bolt 3.
[0024]
Even in the clip 5 of the embodiment shown in FIG. 5, the clip 5 of the other embodiment described above is provided without providing pin holes in the leg portions 3 </ b> A and 3 </ b> B of the square bolt used as the U-shaped bolt 3. It is possible to attach to only one of the leg portions 3A and 3B of the square bolt used as the U-shaped bolt 3 in the same manner.
[0025]
According to the pipe standing band 1 of the present invention using the square bolt and the clip 5 used as the U-shaped bolt 3 as described above, after the pipe P is held in the band part 11 at the site, the band part 11B and the end portion 12B are closed, and nuts 4 and 4 are screwed onto the tips of the leg portions 3A and 3B of the square bolt used as the U-shaped bolt 3 protruding from the end portion 12B. In the prior art, when the nuts 4 and 4 are screwed together, the bolts rotate along with the rotation of the nuts 4 and 4, so the two bolts and nuts can be screwed separately while holding the bolts with fingers. However, in the present invention, the U-shaped bolt 3 is used as the bolt, and the square bolt is used as the U-shaped bolt 3 . Therefore, workability is significantly improved.
[0026]
Further, the presence of the clip 5 makes it possible to prevent the nut 4 from loosening without using a spring washer or the like.
[0027]
As described above, the piping vertical band 1 according to the present invention is in the state shown in FIG. 1, that is, the leg portions 3A and 3B of the square bolt used as the U-shaped bolt 3 are inserted into the end portion 12A of the band portion 11A. In this state, the nuts 4 and 4 are loosely screwed together and shipped from the factory and carried into the site. Depending on the request of the field worker, the end 12B of the band 11B is not inserted into the square bolt legs 3A and 3B used as the U-shaped bolt 3, and the U-shaped bolt 3 remains in the released state of the band 11B. The nuts 4 and 4 may be loosely screwed onto the leg portions 3A and 3B of the square bolts used as
[0028]
【The invention's effect】
According to the present invention, instead of the two bolts that have been conventionally used, a square bolt that is used as one U-shaped bolt is used , so that a clip is conventionally attached to each of the two bolts. Whereas it was necessary to attach a clip to only one of the two legs of a square bolt used as a U-shaped bolt, the nut is removed. The square bolt used as the U-shaped bolt does not fall off from one end of the band portion. Therefore, not only the number of clips used is halved, but also the labor for mounting the clips is halved, so that both the cost reduction and the work labor can be reduced.
[0029]
Furthermore, according to the present invention, the use of the square bolt used as the U-shaped bolt does not cause a problem of accompanying rotation at the time of nut screwing. This eliminates the need for a follow-up prevention tool, which is a separate component as in the already proposed technology, and has the effect of significantly reducing the number of parts, labor required for installation, and cost.
