BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS.
The piping duct D for mounting the end cover member 1 according to the present invention has the following configuration.
The pipe duct D mainly includes a pair of side wall members 2, a canopy member 3 that can be detachably attached to the pair of side wall members 2, and a plurality of pipe supports that connect the pair of side wall members 2. And a member 4. The pipe support member 4 also has a function of mounting various pipes such as a cooler pipe or an electric cable laid inside the pipe duct D.
The side wall member 2 is formed by bending an upper edge 1A and a lower edge 1B. The upper edge 1A is used as a mounting portion for the canopy member 3, and the lower edge 1B is used as a mounting portion for the pipe support member 4. The attachment between the side wall member 2 and the canopy member 3 or the attachment between the side wall member 2 and the pipe support member 4 is performed using, for example, an attachment screw 5 and a nut 6. For this purpose, the upper edge 1A and the lower edge 1B are provided with mounting holes 7 through which the mounting screws 5 are inserted. The nut 6 may be attached to the attachment hole 7 of the upper edge 1A by welding or the like, or may be a nut that directly forms a female screw with respect to the attachment hole 7.
The side wall member 2 or the canopy member 3 is provided with a step 8 along its longitudinal direction X as shown in FIG. 1 in order to improve its strength.
The pipe duct D is normally fixed to the leg member 10 in a state of being placed on the leg member 10. In this case, the lower edge portion 1B of the pipe duct D is sandwiched between the sandwiching member 9 and the leg member 10 and fixed using the mounting screw 5.
[0009]
(End cover and mounting)
The attachment of the end cover member 1 to the pipe duct D may be performed after the canopy member 3 is attached to the side wall member 2 or before the canopy member 3 is attached. FIG. 1 shows the former example.
As shown in FIG. 1, the end cover member 1 has two connecting pieces 11 at two side edges 1C on both sides, and further has an outer fitting projection piece 12 and an inner fitting projection at the upper edge 1A. One piece 13 is provided. FIG. 1 shows an example in which two pairs of the outer fitting protruding pieces 12 and the inner fitting protruding pieces 13 are provided. The reason why the outer fitting protruding pieces 12 are provided at two places is to avoid the step 8 formed on the canopy member 3.
In order to attach the end cover member 1 to the pipe duct D, the respective connecting pieces 11 are inserted inside the side wall member 2, and the two inner fitting protruding pieces 13 are inserted inside the canopy member 3, The two outer fitting protruding pieces 12 are located outside the canopy member 3. FIG. 2 shows a state in which the end cover member 1 is attached.
As a result, since the inner fitting protruding piece 13 and the outer fitting protruding piece 12 sandwich the canopy member 3, no gap is generated between the upper edge 1 </ b> A of the end cover 1 and the canopy member 3. . Therefore, it is possible to effectively prevent rainwater or sunlight from entering from the boundary between the canopy member 3 and the end cover member 1, or prevent the canopy member 3 from vibrating in a strong wind.
When the end cover member 1 is aligned with the piping duct D, the base end portion 12A of the outer fitting projecting piece 12 abuts on the edge 3A of the canopy member 3. Therefore, the end cover member 1 does not enter the inside of the piping duct D too much, and the positioning with respect to the piping duct D is performed by simply pushing the end cover member 1 until the end cover member 1 contacts the canopy member 3. Therefore, the work of attaching the end cover member 1 is facilitated.
[0010]
Although not shown, having the outer fitting protruding piece 12 and the inner fitting protruding piece 13 is also effective when the canopy member 3 is attached last. That is, when the end cover member 1 is first attached to both the side wall members 2 and the canopy member 3 is attached thereafter, the edge 3A of the canopy member 3 is attached to the outer fitting projecting piece 12 and the inner fitting projecting piece. Then, the canopy member 3 may be inserted and pushed into the canopy member 3 until the edge 3A of the canopy member 3 comes into contact with the base end 12A of the external fitting projecting piece 12. Therefore, alignment of the edge 3A of the canopy member 3 is easy, and in particular, when attaching the canopy member 3 to the end cover member 1 provided at the lower end portion of the piping duct D arranged in the vertical direction, the worker It is not necessary to lift and support the canopy member 3, and the work of mounting the canopy member 3 becomes extremely easy.
[0011]
Note that the number of the inner fitting protruding pieces 13 and the number of the outer fitting protruding pieces 12 are not limited to two pairs, and at least one each may be provided. In short, as long as there is no extreme gap between the upper edge 1A of the end cover member 1 and the canopy member 3, the configuration is the above-mentioned inner fitting protruding piece 13 and outer fitting protruding piece 12 The shape is not limited, and the number is arbitrary.
[0012]
