As described above, in the outlet mounting method, the waterproof outlet 20 can be retrofitted to the outer surface 12 of the structure outer plate 11 as the outlet mounting structure 10 having the above-described configuration through the above-described steps.

The outlet mounting structure 10 and the outlet mounting method of the embodiment of the outlet mounting structure according to the present invention can obtain the following operational effects.

The outlet mounting structure 10 includes a sheet-shaped first waterproof member 33 that covers the extraction hole 13 between the outer surface 12 of the structure outer plate 11 and the base material 32 that is attached thereto, and a second waterproof member that surrounds the first waterproof member 33. 34 and 34 are provided in a compressed state. Therefore, the outlet mounting structure 10 has the two waterproof members, the second waterproof member 34 and the first waterproof member 33, in the path extending from the outside of the base material 32 to the outside surface 12. As a result, more reliable waterproofness of the extraction hole 13 can be obtained, and the waterproofness can be improved. Further, the outlet mounting structure 10 has a surface shape in which the first waterproof member 33 covers the peripheral edge of the extraction hole 13, so that the area to be sealed can be expanded and the waterproof property can be improved. In particular, since the outlet mounting structure 10 is caulked with the outer surface 12 over the entire circumference of the first waterproof member 33 (caulking material 46), the waterproof property can be further improved.

Further, in the outlet mounting structure 10, since the base material 32 has a flat plate shape, the first waterproof member 33 and the second waterproof member 34 are securely held between the flat pressing surface 32a and the outer surface 12. It can be compressed uniformly and evenly, and the waterproofness can be further improved.

Further, in the outlet mounting structure 10, the first waterproof member 33 is attached to the outer surface 12 and the second waterproof member 34 is attached to the base material 32. Therefore, in the outlet mounting structure 10, the first waterproof member 33 more reliably seals the space between the outer surface 12 and the second waterproof member 34 in the path extending from the outside of the base material 32 to the outer surface 12. It is possible to more reliably seal the space between the base material 32 and the base material 32, and it is possible to further improve waterproofness.

In the outlet mounting structure 10, since each second screw member 42 is provided between the first waterproof member 33 and the second waterproof member 34 of the base material 32, each second screw member 42 is attached to the first waterproof member 33. Also, it is possible to prevent the waterproof property of the second waterproof member 34 from being deteriorated, and to prevent the peripheral property of each second screw member 42 from serving as a path. In particular, in the outlet mounting structure 10 of the first embodiment, since each second screw member 42 is caulked, it is possible to reliably prevent the periphery of each second screw member 42 from becoming a water line. The same applies to the first screw members 41 that are screwed into the fixing screw holes 32c of the base material 32 to fix the mounting frame 23 to the base material 32, and the waterproofness can be further improved.

In the outlet mounting structure 10, the space between the insertion hole 32b of the base material 32 and the electric wire 14 passing therethrough is sealed by the third waterproof member 35, so that the insertion hole 32b serves as a path and the waterproofness can be prevented from being lowered. .. In particular, in the outlet mounting structure 10 of the first embodiment, since caulking is performed between the third waterproof member 35 and the insertion hole 32b, the waterproof property during this time can be further improved.

In the outlet mounting structure 10, a fourth waterproof member 36 is provided between the mounting frame 23 and the base material 32 so as to correspond to each first screw member 41. For this reason, the outlet mounting structure 10 can seal the path from the fixing screw holes 23a of the mounting frame 23 to the pull-out hole 13 and further improve waterproofness. In addition, in the outlet mounting structure 10, caulking is performed between the outer surface 12 and the upper edge portions and both side edge portions of the outlet cover 22 fitted in the outlet main body 21 attached to the mounting frame 23 (caulking material 47). ), so waterproofness can be obtained during this period.

Since the method of attaching the outlet performs each of the above-mentioned steps, the first waterproof member 33 is provided between the outer side surface 12 and the base material 32 so as to cover the extraction hole 13, and the first waterproof member 33 is surrounded. Thus, it is possible to easily provide the second waterproof member 34 and compress them. Further, in the outlet mounting method, since the back receiving member 31 is inserted from the drawing hole 13 and provided on the inner side surface 15 of the structure outer plate 11, the waterproof outlet 20 can be appropriately attached to the outer surface 12 of the structure outer plate 11 afterwards. It can be provided with strength.

Since the pressing surface 32a of the base material 32 has a flat plate shape so that the pressing surface 32a is a flat surface, the first waterproof member 33 and the second waterproof member 34 are arranged between the pressing surface 32a and the outer surface 12. By doing so, they can be reliably and evenly compressed, and the waterproofness can be further improved. In addition, the base material 32 is a fixing screw hole 32c that can be fixed by screwing the first screw member 41 to which the waterproof outlet 20 is attached, and a mounting screw that allows the second screw member 42 that attaches itself to the outer surface 12 to pass through. The hole 32d and the hole 32d are provided separately. Therefore, the base material 32 is attached to the outer side surface 12 by the second screw member 42 that passes through the attachment screw hole 32d while interposing the first waterproof member 33 and the second waterproof member 34, and the insertion hole 32b and the electric wire 14 are connected. By sealing the space with the third waterproof member 35, more reliable waterproofness of the extraction hole 13 can be obtained. Further, the base material 32 can be attached to the waterproof outlet 20 (its mounting frame 23) by screwing the first screw member 41 into the fixing screw hole 32c, so that the waterproof property of the drawer hole 13 can be ensured while being used for general purpose. A waterproof outlet (20) can be attached. From these things, the base material 32 can provide a waterproof outlet on the outer surface 12 of the structure outer plate 11 while retrofitting it while ensuring the waterproof performance.

Therefore, in the outlet mounting structure 10 of the first embodiment as the outlet mounting structure according to the present invention, it is possible to improve the waterproof property and provide the waterproof outlet 20 on the outer surface 12 of the structure outer plate 11.
