JPS5838749Y2 - Rainproof cover for bus duct - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to improvements in rainproof covers for outdoor bus ducts and the like.

As shown in Fig. 1, the conventional rainproof cover is a rainproof cover 1 with a U-shaped cross section that covers the bus duct (BD) from above with the opening side facing downward. However, since it cannot be bent at once, the 1-shaped half-split parts IA and IA are assembled by welding 2, which is time-consuming and difficult to handle due to the large size.

Also, the heat dissipation of the bus duct is poor.

The present invention aims to obtain a rainproof cover that does not require the above-mentioned welding, has smaller parts, is easy to assemble, and has excellent ventilation performance. In the rainproof structure that covers the upper and side parts, an upper plate element 11 is provided above the bath duct (BD) and has a draining drooping part 10.10 that projects on both sides of the bath duct, and Side plates 13, 13 formed by bending the upper ends laterally to form attachment parts 12.12.
is provided, and the mounting portions 12.12 of the side plates 13, 13 are provided.
is located inside the hanging portion 10.10, and the mounting portion and the upper plate 11 are connected at predetermined positions in the longitudinal direction while maintaining predetermined intervals with spacing members,
This rainproof cover is made up of side plates 13, 13 arranged with a gap between them and the lower surface of the top plate 11.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be explained below with reference to FIGS. 2 to 5.

In the embodiment of FIG. 2, the hanging portion 10. A steel spacing member 14.14 is interposed between the upper mounting part 12.12 of the side plates 13, 13 arranged inside the IO and the upper plate 11, and the pole 15.15 is attached to the mounting part 12. .12
It is connected by screwing into the

There is a slight rising part 12a, 1 at the tip of the mounting part 12゜12.
2a is formed, which means that in the unlikely event that water leaks from the bolt penetration part of the upper plate 11 onto the mounting part 12, it will be absorbed by the bath duct)B
It should be formed so that it does not fall onto D.

In the embodiment shown in FIG.
Install the spacing member 14'j4' on the upper side, attach the N-type adapter 16 above it, connect it to the side plate by 15.15, and attach the upper plate 1 further above the adapter 16.
1, and both bent ends 16a, 15 of the adapter 16.
a and a hanging portion 10.10 are connected by screws 17.17.

In the case of the above embodiment, by using the one-type adapter 16, there is no need to pass bolts through the upper surface of the upper plate 11, and there is no fear of water leakage.

In the above two embodiments, the spacing member 14, 14' is a piece having a thread groove, and the piece is welded to the mounting portion so that the screws for attaching the upper plate are tightened using the thread groove. You can also do that.

In the embodiment shown in FIG. 4, a one-shaped plate-shaped spacing member 14'' is attached to the mounting portions 12.12 of the side plates 13, 13 with screws, and the upper plate 11 is attached to the hanging portion 10.10 above the spacing member 14''. Part 1
Both bent portions 14''a, 14''a of 4'' are secured with screws 18 and arranged with a gap from the mounting portion.

In the embodiment shown in FIG.
A shaped spacing member 14'' is provided between the rising portions 12a, 12a formed at the tips and the upper plate 11, and is fixed at each attached portion with screws 19 and 20.

The bus duct) BD and the rainproof cover are connected as appropriate, for example, by placing a U-shaped single plate 21 as shown in FIG. 2 on the lower side of the bus duct and installing it between the side plates 13, 13.

Since the present invention is constructed as described above, rain etc.
Since the side plate is attached to the upper plate inside the hanging part 10.10, there is no intrusion of water, and the spacing member 14 .14', 14", and 14"' are connected while maintaining a predetermined interval, the heat dissipated from the bus duct) BD is released through the gap between the top plate 11 and the side plate 13. Since fresh air is always taken in from below the side plates 13, 13 by convection, sufficient cooling can be achieved.

As explained above, the rainproof cover of the present invention can be disassembled into the top plate element and the side plate element, making it easier to handle due to the lighter weight and smaller size of the individual parts, making it very easy to work with. It is possible to significantly improve ventilation cooling.
