Description

[Technical field]

[0001] The present invention relates to a pipe support stand suitable for supporting pipes in tunnels, for supporting pipes for lighting equipment on bridges, or for supporting pipes related to road infrastructure, for example. [Background technology]

[0002] In wiring work, a channel material is fixed to the ceiling or wall surface with anchor bolts, and the pipes are supported on this channel material with pipe clips.

[0003] In particular, in the case of pipe supports at tunnel entrances and road infrastructure pipe supports, measures are required to prevent the installed pipes from falling due to the constant vibration environment.

[0004] Meanwhile, a conventional pipe support fitting used for horizontal piping is described in Patent Document 1. This pipe support fitting has a configuration in which a slide plate is placed inside a channel material, and a pipe clip is bolted from the outside of the lip to the slide plate that is placed against the inside of the lip.

[0005] This pipe support bracket allows the horizontal pipe to be fixed at any desired height when the horizontal pipe is fixed close to a side wall.

[0006] Furthermore, a conventional method for preventing pipes from falling off when laying horizontal piping involves placing a separate fall prevention device on the underside of the pipe support fittings that support the horizontal piping and fastening it with bolts.

[0007] [Patent Document 1] Patent No. 6180556 Summary of the Invention [Problem to be solved by the invention]

[0008] The pipe support fitting described in Patent Document 1 has a structure in which a slide plate is placed on the inside of the lip and a pipe clip is bolted to the slide plate. Therefore, if the bolts that secure the pipe clip become loose, the secured pipe may fall off.

[0009] In particular, pipe supports at tunnel entrances, pipe supports for bridge lighting equipment, and pipe supports related to road infrastructure are constantly exposed to vibration, which means that the bolts on the pipe clips can loosen, causing the pipes to fall off.

[0010] Furthermore, the conventional method of separately arranging a fall prevention device below the pipe support fitting had the disadvantage of increasing the number of parts used and the number of work steps.

[0011] The present invention was created to solve the above-mentioned problems, and aims to provide a piping support stand that can prevent the piping clip and piping from falling off even if the bolts that secure the piping clip in place come loose, and that also reduces the number of parts and work processes. [Means for solving the problem]

[0012] In order to achieve the above object, the first means of the present invention is a support stand for supporting piping, which has a lip portion 2 inside a support body 1 formed of a channel material and has a fastening end portion 11 of a piping clip 10 fastened to the lip portion 2 inside the support body 1, The above A projection 4 for preventing falling off is provided on the inner surface of the base body 1.

[0022] When the piping support rack of the present invention is used, for example, to support piping at a tunnel entrance or piping related to road infrastructure, the piping P is supported and fixed to the rack body 1 made of a channel material by a piping clip 10 (see FIG. 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 a channel material (see FIG. 1).

[0023] The illustrated rack body 1 is provided with a locking protrusion 3 that continues along the inside of the lip portion 2 of the rack body 1 (see FIG. 2). The locking protrusion 3 is configured to lock a locking end 11 of a piping clip 10. The locking protrusion 3 increases the locking strength of the locking end 11.

[0024] Then, anti-fall-off protrusions 4 are provided on the inner surface of the frame body 1 (see FIG. 3). By providing the anti-fall-off protrusions 4 protruding toward the inside of the frame body 1 in this manner, if the locking end 11 of the piping clip 10 fixing the piping P comes off the lip portion 2 due to vibration or the like, the locking end 11 will lock onto the anti-fall-off protrusions 4, thereby preventing the piping P from falling off (see FIG. 2).

[0025] The illustrated fall-prevention protrusions 4 are formed by cutting and raising the side surface 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 and raising them on the bottom plate or lip portion of the gantry body 1. Furthermore, the fall-prevention protrusions 4 need only be located below one of the engagement ends 11, and the fixing location of the piping P can be freely selected within that range. Also, it is possible to provide a fall-prevention protrusion 4 separate from the gantry body 1 in the illustrated example so that it protrudes inward of the gantry body 1.

[0026] The fall-prevention projection 4 is positioned so that if the locking end 11 comes off the lip portion 2, the fall-prevention projection 4 will lock onto the locking end 11. Therefore, the fall-prevention projection 4 is positioned below and close to the piping clip 10 that supports the horizontal piping (see FIG. 2). The illustrated fall-prevention projection 4 is positioned outside the upper and lower locking ends 11 of the piping clip 10 (see FIG. 1). In this way, even if the frame body 1 is turned upside down, the fall-prevention projection 4 will always be located below and close to the piping clip 10.

[0027] In other words, the shape of the projection 4 is not limited as long as it is disposed below the piping clip 10 at a position where the engaging end 11 of the piping clip 10 will engage if the engaging end 11 comes off the lip portion 2. For example, it is possible to achieve the same function by changing the direction of the cut and raised part, or by changing to burring or embossing.

[0028] Furthermore, the length of the frame body 1 can be selected depending on the number of pipes P to be fixed. The number of fall-off prevention protrusions 4 can also be changed depending on the number of pipes P to be fixed. For example, when fixing one pipe P, four fall-off prevention protrusions 4 are formed at the outer positions of each locking end 11 of the pipe clip 10 (see FIG. 4).

[0029] Furthermore, when fixing two pipes P, a total of eight fall-prevention protrusions 4 are formed on the longer frame body 1 (see FIG. 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 according to the number of pipe clips 10 used.

[0030] An anchor bolt 20 is used to secure the mount body 1 to a ceiling or wall (see FIG. 3). In the illustrated example, the anchor bolt 20 is inserted into a bolt insertion hole 5 drilled in the mount body 1, and is secured using a locking nut 21 and a disc spring washer 22 (see FIGS. 4 and 5). In this way, by using the locking nut 21 and the disc spring washer 22 together, construction can be carried out with double fall prevention measures in place.

[0031] On the other hand, the piping clip 10 that fixes 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 FIG. 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 the other end of the clamping pieces 12 is formed with a connecting portion 13.

[0032] To secure a pipe P with this pipe clip 10, the engaging ends 11 of each clamping piece 12 are 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, thereby securing the pipe clip 10 clamping the pipe P to the frame body 1 (see Figure 1).

[0033] The support rack of the present invention is often used outdoors on roads, bridges, etc. (See FIG. 6.) Therefore, the materials of the rack body 1, the pipe clip 10, the anchor bolt 20, etc. are preferably made of a material with excellent corrosion resistance such as stainless steel.

[0034] Furthermore, the various configurations of the present invention are not limited to the examples shown in the drawings, and the shape of the rack body 1 and the piping clip 10, or the shape, number, configuration, size, etc. of the anti-fall-off protrusions 4 are freely subject to design changes as long as they do not change the gist of the present invention.
