Description

The present invention relates to a pipe support stand that is suitable for supporting pipes in tunnels, pipes for bridge lighting equipment, or pipes related to road infrastructure.

During wiring work, the channel material is fixed to the ceiling or wall surface with anchor bolts, and the piping is supported on this channel material with piping clips.

In particular, in pipe supports at tunnel entrances and in road infrastructure, measures are required to prevent the installed pipes from falling due to constant vibrations.

Meanwhile, a conventional pipe support fitting used for horizontal piping is described in Patent Document 1. This pipe support fitting has a slide plate placed inside the channel material, and a pipe clip is bolted from the outside of the lip to the slide plate placed against the inside of the lip.

This pipe support bracket allows horizontal pipes to be fixed at any height when they are close to a side wall.

In addition, a conventional method for preventing pipes from falling off when laying horizontal piping involves placing a fall prevention device separately on the underside of the pipe support fittings that support the horizontal piping and fastening it with bolts.

Patent No. 6180556

The pipe support fixture described in Patent Document 1 is configured so that a slide plate is placed on the inside of the lip and the pipe clip is bolted to the slide plate. Therefore, if the bolts that secure the pipe clip become loose, there is a risk that the secured pipe will fall off.

In particular, pipe supports at tunnel entrances, pipe supports for bridge lighting equipment, and pipe supports related to road infrastructure are in an environment where constant vibrations are present, which can cause the bolts on the pipe clips to loosen and cause the pipes to fall off.

In addition, the conventional method of separately placing fall prevention devices below the pipe support fittings had the disadvantage of increasing the number of parts used and work processes.

The present invention was created to solve the above problems, and aims to provide a pipe support stand that can prevent the pipe clip and pipe from falling off even if the bolts that secure the pipe clip become loose, and that also reduces the number of parts and work steps.

In order to achieve the above-mentioned object, the first means of the present invention is a support stand for supporting piping, which engages a fastening end 11 of a piping clip 10 on the inside of a lip portion 2 of a stand main body 1 formed of a channel material, and has an anti-fall-off protrusion 4 protruding from the inner surface of the stand main body 1, and is configured so that when the fastening end 11 of the piping clip 10 comes off the lip portion 2, the fastening end 11 engages with the anti-fall-off protrusion 4.

The fall prevention protrusion 4 of the second means is positioned below and close to the piping clip 10 that supports the horizontal piping.

The fall-off prevention projection 4 of the third means is disposed adjacent to and below either one of the upper and lower engaging ends 11 of the piping clip 10, or adjacent to and below each of the engaging ends 11 .

The anti-falling protrusion 4 of the fourth means is positioned above and close to either one of the upper and lower engaging ends 11 of the piping clip 10, or above and close to each of the engaging ends 11, and when the top-bottom orientation of the frame main body 1 is reversed, the anti-falling protrusion 4 is positioned below and close to the piping clip 10 .

The fall-off prevention protrusions 4 of the fifth means are formed by cutting and raising the side surface, bottom plate or lip portion 2 of the pedestal body 1 inward, or by burring or embossing .

The fall-off prevention projection 4 of the sixth means is provided separately from the gantry body 1 so as to project inwardly from the gantry body 1 .

The seventh means is further provided with a locking projection 3 that is continuous along the inside of the lip portion 2 of the gantry body 1, and the locking end portion 11 is locked to the locking projection 3 .

As in the present invention, the inner surface of the frame body 1 is provided with a fall prevention protrusion 4 that prevents the engaging end 11 of the piping clip 10 from falling off when the engaging end 11 comes off the lip portion 2. This makes it possible to prevent the piping from falling off even if the bolt that fastens the piping clip becomes loose. Moreover, the number of parts and work steps can be reduced compared to conventional construction methods.

As a result, it is particularly suitable for supporting pipes in environments with a lot of vibration, such as supporting pipes at tunnel entrances, supporting pipes for bridge lighting equipment, or supporting pipes related to road infrastructure.

FIG. 4 is a bottom view showing the state in which the present invention is used. FIG. 1 is an exploded perspective view showing an embodiment of the present invention. FIG. 11 is an exploded perspective view showing another embodiment of the present invention. FIG. 1 is a cross-sectional view showing an example of use of the present invention.

When the piping support rack of the present invention is used, for example, to support piping at tunnel entrances or road infrastructure piping, the piping P is supported and fixed to the rack body 1 made of channel material with a piping clip 10 (see Figure 6). That is, the piping P is fixed by engaging the engaging end 11 of the piping clip 10 with the inside of the lip portion 2 of the rack body 1 made of channel material (see Figure 1).

The illustrated mount body 1 has a locking protrusion 3 that continues along the inside of the lip portion 2 of the mount body 1 (see FIG. 2). The locking protrusion 3 is configured to lock the locking end 11 of the piping clip 10. The locking protrusion 3 increases the locking strength of the locking end 11.

Then, anti-fall-off protrusions 4 are provided on the inner surface of the frame body 1 (see Figure 3). By providing the anti-fall-off protrusions 4 protruding inward from the frame body 1 in this way, if the engaging end 11 of the pipe clip 10 that secures the pipe P comes off the lip portion 2 due to vibration or the like, the engaging end 11 engages with the anti-fall-off protrusions 4, preventing the pipe P from falling off (see Figure 2).

The illustrated fall prevention protrusions 4 are formed by cutting the side of the gantry body 1 inward (see Figs. 1 and 2). In this case, a pair of fall prevention protrusions 4 are formed on opposing side surfaces of the gantry body 1, but it is also possible to form an appropriate number of fall prevention protrusions 4 by cutting them into the bottom plate or lip of the gantry body 1. Furthermore, the fall prevention protrusions 4 only need to be located below one of the engagement ends 11, and the fixing location of the piping P can be freely selected within that range. It is also possible to provide fall prevention protrusions 4 separate from the gantry body 1 in the illustrated example so that they protrude inward of the gantry body 1.

This anti-falloff protrusion 4 is positioned so that if the engaging end 11 comes off the lip portion 2, the engaging end 11 will engage with the anti-falloff protrusion 4. Therefore, the anti-falloff protrusion 4 is positioned below and close to the piping clip 10 that supports the horizontal piping (see Figure 2). The illustrated anti-falloff protrusion 4 is positioned outside the upper and lower engaging ends 11 of the piping clip 10 (see Figure 1). In this way, even if the top and bottom of the frame body 1 are reversed, the anti-falloff protrusion 4 will always be located below and close to the piping clip 10.

In other words, the fall-prevention projection 4 is only required to be located below the piping clip 10 in a position where the engaging end 11 of the piping clip 10 will engage if it comes off the lip portion 2, and the shape of the projection is not limited. For example, it is possible to change the direction of the cut and bend, or to use burring or embossing, etc., and still achieve the same function.

Furthermore, the length of the frame body 1 can be selected depending on the number of pipes P to be fixed. The number of anti-fallout protrusions 4 can also be changed depending on the number of pipes P to be fixed. For example, when fixing one pipe P, four anti-fallout protrusions 4 are formed at the outer positions of each engaging end 11 of the pipe clip 10 (see Figure 4).

Furthermore, when fixing two pipes P, a total of eight fall prevention protrusions 4 are formed on the longer frame body 1 (see Figure 5). In this way, when the number of pipes P to be fixed increases, the length of the frame body 1 and the number of fall prevention protrusions 4 can be adjusted to match the number of pipe clips 10 used.

Anchor bolts 20 are used to secure the stand body 1 to a ceiling or wall (see Figure 3). In the illustrated example, the anchor bolts 20 are inserted into the bolt insertion holes 5 drilled in the stand body 1, and are secured using locking nuts 21 and disc spring washers 22 (see Figures 4 and 5). In this way, by using the locking nuts 21 and disc spring washers 22 together, construction can be carried out with double fall prevention measures in place.

On the other hand, the piping clip 10 that secures the piping P to the frame body 1 is a typical piping clip 10 that uses a pair of clamping pieces 12 that clamp the piping P (see Figure 1). That is, one end of the clamping pieces 12 is provided with a hook-shaped locking end 11 that locks onto the inside of the lip portion 2, and a connecting portion 13 is formed on the other end of the clamping pieces 12.

To secure the pipe P with this pipe clip 10, the engaging end 11 of each clamping piece 12 is engaged with the inside of the lip portion 2 of the frame body 1, and the connecting portions 13 are bolted together with connecting bolts 14, so that the pipe clip 10 clamping the pipe P is secured to the frame body 1 (see Figure 1).

The support rack of the present invention is often used outdoors, such as on roads and bridges (see Figure 6). Therefore, it is preferable that the material of the rack body 1, the pipe clip 10, the anchor bolt 20, etc. be a material with excellent corrosion resistance, such as stainless steel.

The configurations of the present invention are not limited to the examples shown in the drawings, and the shape of the mounting body 1 and the piping clip 10, or the shape, number, configuration, size, etc. of the fall prevention protrusions 4 may be freely modified in design within the scope that does not change the gist of the present invention.
