TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pipe support fitting, and more particularly, to a pipe support fitting for supporting a pipe such as an electrical conduit for wiring an electric wire or a column forming a frame.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as shown in FIG. 6, a pipe support fitting for supporting an electrical conduit or the like on an H-section steel or an L-section steel has been known. The pipe support fitting 50 is attached so as to sandwich a member to be mounted such as an H-shaped steel, and has a fitting body 51 having a substantially U-shaped cross section and a first plate-shaped portion 52 of the fitting body 51. It is composed of a screwed male screw 53 and an auxiliary metal fitting 57 that can be attached to two mounting holes 56 formed in the second plate-shaped portion 54 and the third plate-shaped portion 55 of the metal fitting body 51, respectively. ing.
[0003]
That is, when the male screw 53 is tightened with the member to be mounted inserted between the first plate-shaped portion 52 and the third plate-shaped portion 55, the male screw 53 is covered by the distal end of the male screw 53 and the third plate-shaped portion 55. The mounting member is clamped, and the fitting body 51 is fixed to the mounted member. Then, in this state, the pipe is attached to the second plate-shaped portion 54 or the third plate-shaped portion 55 via the auxiliary fitting 57, so that the pipe is supported by the member to be mounted. The auxiliary fitting 57 is, for example, a pair of fixed bands that are fastened to each other while sandwiching the outer peripheral surface of the pipe, and a hook 57 a formed at one end of the fixed band is hooked into the mounting hole 56. In some cases, the pipe is attached to the fitting main body 51.
[0004]
At the time of filing the present application, the applicant has found the following documents describing the above-mentioned prior art.

[Problems to be solved by the invention]
However, in the pipe support fitting 50 described above, since the male screw 53 is screwed into the approximate center of the first plate-shaped portion 52, the mounting hole 56 cannot be formed in the first plate-shaped portion 52. In addition, the first plate-shaped portion 52 is formed relatively long, and a screw hole for screwing the male screw 53 and a mounting hole 56 for mounting the auxiliary metal fitting 57 are arranged side by side on the first plate-shaped portion 52. However, since the head 53a of the screwed male screw 53 protrudes from the upper surface of the first plate-shaped portion 52, the head 53a of the male screw 53 becomes an obstacle when supporting the pipe, and May be difficult to support.
[0006]
Therefore, at the site, the orientation of the fitting body 51 is determined in consideration of the shape of the member to be mounted and the location and direction of the piping. For example, when it is desired to arrange a pipe on the near side with respect to the mounted member, the third plate-shaped portion 55 in which the mounting hole 56 is formed is positioned in front of the mounted member, and the male screw 53 is screwed. The first plate-shaped portion 52 is fixed in a state of being located behind the mounted member. However, in this case, since the head 53a of the male screw 53 operated when screwing the male screw 53 is located behind the mounted member, there is a possibility that the tightening operation may be difficult. In particular, when a sufficient space is not secured behind the mounted member, it becomes difficult to insert a hand or a tool of the worker, and the burden on the worker becomes extremely large.
[0007]
Further, in the conventional pipe support fitting 50, since one male screw 53 screwed to the first plate-shaped portion 52 is pressed against one surface of the mounted member, for example, it is fixed. When a force in the rotation direction about the male screw 53 is applied between the mounted member and the fitting body 51, the male screw 53 may rotate in a loosening direction. In other words, since it is supported at one point, it cannot be fixed stably.
[0008]
Further, in the conventional metal fitting body 51, only one mounting hole 56 is provided for each of the second plate-shaped portion 54 and the third plate-shaped portion 55, and thus, for example, two pipes are arranged in parallel. In this case, the pipe has to be supported by the second plate portion 54 and the third plate portion 55 which are perpendicular to each other. That is, when one of the pipes is disposed in front of the mounted member, the other pipe has to be disposed on a surface different from the one pipe by 90 °, for example, on the left side of the mounted member. . For this reason, the two pipes are stepped from each other, impairing the overall appearance, and requiring a relatively large space for installation.
[0009]
In view of the above situation, the present invention provides a pipe support fitting capable of extremely easily and stably attaching a fitting body to a member to be mounted, and capable of increasing the number of supportable pipes. And a second object is to provide a pipe support which allows two pipes to be arranged in an attractive manner without impairing the ease of attachment to a member to be mounted.
[0010]
[Means for Solving the Problems]
The pipe support fitting according to the first aspect of the present invention includes a first plate-like portion having a substantially plate-like shape, a second plate-like portion bent substantially perpendicular to the first plate-like portion, and the second plate-like portion. A metal plate body having a substantially U-shaped cross-section, a third plate-shaped portion bent substantially perpendicular to the shape portion, the first plate-shaped portion, the second plate-shaped portion, and the A mounting portion formed on the third plate-shaped portion, to which an auxiliary fitting for supporting a pipe can be mounted, and a pair of projecting portions projecting outward from both ends in the width direction of the first plate-shaped portion; And the holding member screwed to the protruding portion and inserted between the first plate-shaped portion and the third plate-shaped portion, in cooperation with the third plate-shaped portion. And a male screw.
[0011]
Here, the “substantially plate-like shape” includes not only a plate-like shape but also a curved shape, for example. As the “mounting portion”, a mounting hole formed in each plate portion can be exemplified.
[0012]
Therefore, according to the pipe support fitting of the first aspect of the present invention, the mounted member is inserted between the first plate-shaped portion and the third plate-shaped portion, and then the male screw is screwed into the pair of projecting portions. Then, the mounted member is sandwiched by the cooperation of the male screw and the third plate-shaped portion. Since the mounted member is supported at two points with respect to the metal fitting main body, there is no possibility that the male screw will rotate in the loosening direction, and the mounting can be stably fixed. Further, even when the pipe is mounted on the first plate-shaped portion, the male screw head does not become an obstacle, so that an auxiliary fitting for supporting the pipe can be mounted. Thereby, the auxiliary fitting for supporting the pipe can be attached to any of the first plate-shaped part, the second plate-shaped part, and the third plate-shaped part, and the position of the male screw is restricted depending on the arrangement location of the pipe. Instead, the mounting direction of the bracket can be freely changed in accordance with the operation of screwing the male screw.
[0013]
The pipe support fitting according to the invention of claim 2 is the pipe support fitting according to claim 1, wherein at least one of the first plate-shaped part and the third plate-shaped part is opposite to the second plate-shaped part. It further includes an extended portion and a second attachment portion formed on the extension portion and capable of attaching the auxiliary fitting.
[0014]
Therefore, according to the second aspect of the present invention, in addition to the function of the first aspect of the present invention, since the second mounting portion is provided, the number of pipes that can be supported increases. By arranging the pipes on the second mounting portion provided on the extended portion, it is possible to arrange two pipes side by side on one plate-like portion, and the overall appearance is improved.
[0015]
According to a third aspect of the present invention, there is provided the pipe support fitting according to the second aspect, wherein the extending portion is formed only on one of the first plate-shaped portion and the third plate-shaped portion. Is what it is.
[0016]
By the way, in the configuration of claim 2, when the extending portion is formed on both the first plate-shaped portion and the third plate-shaped portion, the following inconvenience occurs. That is, the H-shaped steel and the L-shaped steel have a surface perpendicular to a portion inserted between the first plate-shaped portion and the third plate-shaped portion, and they are formed only in one direction. If the extending portions are formed on both the one plate portion and the third plate portion, the vertical surface may become an obstacle, and there is a possibility that the pipe support fitting cannot be attached. If the position of the protruding portion to which the male screw is screwed is changed to the distal end of the extending portion, attachment becomes possible, but a relatively large space is required for installation. However, according to the pipe support fitting of the third aspect of the invention, in addition to the operation of the second aspect of the present invention, the extended portion is formed on one of the first plate portion and the third plate portion. On the other hand, when the member to be mounted is inserted, the pipe support can be attached without being affected by the vertical surface, and a large space is not required at the time of installation.
[0017]

Further, reinforcing portions 8 are formed at both ends in the width direction of each of the plate portions 5, 6, and 7 so as to bend vertically outward. The end of the reinforcing portion 8 extends in the U-shaped inner circumferential direction to form a reinforcing extension 9, and the tip of the reinforcing extension 9 is located inside the plate-like portions 5, 6, 7. positioned. A corrugated portion 12 is formed at the end of the reinforcing extension 9 extending from the third plate-shaped portion 7 for the purpose of preventing slippage.
[0019]
The mounting portion 2 is formed on each of the first plate-shaped portion 5, the second plate-shaped portion 6, and the third plate-shaped portion 7, and in this example, is configured with a mounting hole.
[0020]
As shown in FIG. 3, the auxiliary fitting 16 has a structure in which the pipe 14 is clamped by a semicircular holding portion 15, and has an end hooked at one end so as to be able to be hooked to the mounting section 2 of the pipe support fitting 10. A stop portion 13 is provided, and a through hole (not shown) is formed at the other end where a semicircular holding portion 15 for holding the pipe 14 is extended, and a bolt 17 passed through the through hole is provided. Is tightened to the nut 18 so that the pinch can be adjusted. The hook 13 of the auxiliary fitting 16 is hooked and fixed to the attachment 2 of the pipe support 10.
[0021]
As shown in FIGS. 1 and 2, the protruding portion 3 protrudes outward from the lower end in the width direction of the reinforcing extension 9 in the first plate-shaped portion 5. The male screw 4 is screwed into the protruding portion 3 so as to pinch the mounted member in cooperation with the third plate-shaped portion 7. Since the head protrudes from the lower end, the head of the male screw 4 does not become an obstacle when supporting the pipe 14.
[0022]
Here, a method of using the pipe support fitting 10 of the first embodiment will be described with reference to FIG. In order to use the pipe support fitting 10 shown in FIG. 3 to support the pipe 14 such as a power distribution tube or a support, first, the mounted member 11 includes the first plate-shaped portion 5 and the third plate-shaped portion of the pipe support fitting 10. The pipe support fitting 10 is installed so as to be inserted between the portion 7.

Furthermore, the hook 13 of the auxiliary fitting 16 attached to the pipe 14 such as an electric conduit or a support is hooked and fixed to the attachment 2 of the pipe support 10.
[0023]
As described above, according to the pipe support fitting 10 of the first embodiment, since the third plate-shaped portion 7 and the two male screws 4 are fixed to the mounted member 11, the mounted member 11 and the fitting main body are fixed. Even when a force that rotates the male screw 4 in the direction in which the male screw 4 is loosened is applied, the male screw 4 is not loosened, and the possibility that the position of the pipe support 10 is shifted is reduced. That is, the pipe support fitting 10 can be fixed stably.
[0024]
Since the projecting portions 3 to which the male screw 4 is screwed are formed at both ends in the width direction of the first plate-shaped portion 5, when the male screw 4 is screwed, the head of the male screw 4 may be obstructed. Instead, the hook 13 of the auxiliary fitting 16 attached to the pipe 14 such as an electric conduit or a support can also be hooked to the first plate-shaped portion 5. Accordingly, the position of the male screw 4 is not restricted by the location of the pipe 14, and the mounting direction of the metal fitting can be freely changed according to the operation of screwing the male screw 4.
[0025]
Next, a pipe support fitting 40 according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a perspective view of the pipe support fitting 40, and FIG. 5 is an explanatory diagram for explaining a use state of the pipe support fitting 40.
