Description

[Technical Field]

[0001] The present invention relates to a pipe support frame suitable for supporting pipes in tunnels, pipes for lighting equipment on bridges, or 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, pipe supports at tunnel entrances and road infrastructure pipe supports are constantly subjected to vibrations, so measures are required to prevent the installed pipes from falling.

[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 height when it is near a side wall.

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

[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 inside 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 in an environment where vibrations are constantly present, which can cause the bolts on pipe clips to loosen and the pipes to fall off.

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

[0011] Therefore, 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 loosen, and that also reduces the number of parts and work steps. [Means for solving the problem]

[0012] In order to achieve the above object, a first aspect of the present invention is a support stand for supporting piping, in which a fastening end portion (11) of a piping clip (10) is fastened to an inner side of a lip portion (2) of a support main body (1) formed of a channel material, The aforementioned A projection 4 for preventing falling off is provided on the inner surface of the base body 1, The aforementioned The engaging end 11 of the piping clip 10 The aforementioned When it comes off from lip part 2, The aforementioned The locking end 11 The aforementioned The structure is such that it is engaged with the fall-off prevention protrusion 4.

[0022] When the piping support rack of the present invention is used, for example, to support piping at a tunnel entrance or for supporting piping related to road infrastructure, the piping P is supported and fixed to the rack body 1 made of a channel material with piping clips 10 (see FIG. 6). That is, the piping P is fixed by locking the locking end 11 of the piping clip 10 to the inside of the lip portion 2 of the rack body 1 made of a channel material (see FIG. 1).

[0023] The illustrated gantry body 1 has a locking protrusion 3 that continues along the inside of the lip portion 2 of the gantry body 1 (see FIG. 2). The gantry body 1 is configured so that a locking end 11 of a piping clip 10 is locked to the locking protrusion 3. 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 gantry body 1 (see Fig. 3). By providing anti-fall-off protrusions 4 protruding inward of the gantry body 1 in this way, if the locking end 11 of the piping clip 10 that secures the piping P comes off the lip portion 2 due to vibration or the like, the locking end 11 will be locked 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 of the gantry body 1 inward (see Figures 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 only need to be located below one of the locking ends 11, and the fixing location of the piping P can be freely selected within that range. Furthermore, it is also possible to provide fall prevention protrusions 4 separate from the gantry body 1 in the illustrated example so that they protrude inside the gantry body 1.

[0026] This fall prevention protrusion 4 is positioned so that if the locking end 11 comes off the lip portion 2, this locking end 11 will lock onto the fall prevention protrusion 4. For this reason, the fall prevention protrusion 4 is positioned below and close to the piping clip 10 that supports the horizontal piping (see FIG. 2). The illustrated fall prevention protrusion 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 top and bottom of the frame body 1 are reversed, the fall prevention protrusion 4 will always be positioned below and close to the piping clip 10.

[0027] In other words, the shape of the protrusion is not limited as long as it is disposed below the piping clip 10 in 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 change the direction of the cut and bend, or to use burring or embossing, etc., and still achieve the same function.

[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 two pipes P are to be fixed, 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 to match the number of pipe clips 10 to be used.

[0030] Anchor bolts 20 are used to secure the mount body 1 to a ceiling or wall (see Figure 3). In the illustrated example, the anchor bolts 20 are inserted into bolt insertion holes 5 drilled in the mount 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.

[0031] 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 FIG. 1). That is, one end of the clamping piece 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 piece 12 is formed with a connecting portion 13.

[0032] To secure the piping P with this piping 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, thereby securing the piping clip 10, which is clamping the piping P, to the frame body 1 (see Figure 1).

[0033] The support frame of the present invention is often used outdoors on roads, bridges, etc. (See FIG. 6.) Therefore, it is desirable that the material of the frame body 1, the piping clip 10, the anchor bolt 20, etc. be 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 frame body 1 and the piping clip 10, or the shape, number, configuration, size, etc. of the anti-fall protrusions 4 may be freely modified in design within the scope that does not change the gist of the present invention.
