The draining arrangement step S1 is a step of arranging the waste draining material 4 provided with the watertight material 5 so as to cover the rising portion 3 from above. In this step S1, the watertight material 5 is provided in advance on the upper surface of the draining material 4 so as to surround the through hole 33. The waste drainer 4 provided with the watertight material 5 is placed on the support frame 12 so that the handrail support 9 is passed through the through hole 33 and the watertight material 5 from above the handrail support 9. Then, the waste drainer 4 is fixed to the support frame 12 with screws or the like. Therefore, the waste drainer 4 is arranged so as to cover the rising portion 3 from above with the handrail support 9 penetrating the through hole 33.

The holding tool arranging step S2 is a step of arranging the watertight material holding tool 6 on the upper surface of the draining material 4 provided with the watertight material 5. In this step S2, the watertight material retainer 6 is adhered to the upper surface of the draining material 4 with double-sided tape 39 so that the handrail support 9 is passed through the through hole 36 from above the handrail support 9. As described above, since the watertight material holding tool 6 has a holding portion 38, by discarding the watertight material holding tool 6 and providing it on the draining material 4, the holding portion 38 is elastic so as to come into contact with the watertight material 5 and stand up. While deforming, the watertight material 5 is pressed against the handrail column 9 and the drainer material 4. At this time, the watertight material 5 is elastically deformed so as to be crushed and pressed against the handrail column 9 and the drainer material 4. Further, as described above, the double-sided tape 39 is not provided at both the front and rear ends of the watertight material retainer 6. Therefore, when the watertight material presser 6 is provided on the drainer 4, a gap is formed between the front end of the watertight material presser 6 and the drainer 4 and the watertight material presser 6 is opened forward. A gap that opens rearward is formed between the rear end of 6 and the drainer 4.

The lower cap tree arrangement step S3 is a step of arranging the lower cap tree 7 so as to cover the waste drainer 4 arranged on the rising portion 3 from above. In this step S3, the pressing material 8 is provided in advance on the lower surface of the lower cap wood 7 so as to surround the insertion hole 43. The lower cap wood 7 provided with the pressing material 8 is arranged above the draining material 4 so that the handrail support 9 is passed through the insertion hole 43 and the pressing material 8 from above the handrail support 9. At this time, the lower cap wood 7 is provided on the drainer 4 by the attachment 44 and the attachment 45 as described above. Therefore, the lower cap wood 7 is arranged so as to cover the drainer drainer 4 from above with the handrail support 9 penetrating the insertion hole 43. By arranging the lower cap wood 7 above the waste drainer 4, the watertight material 5 pressed against the handrail support 9 and the waste drainer 4 by the watertight material retainer 6 is watertight by the pressing material 8 of the lower cap wood 7. Since the pressing portion 38 of the material pressing tool 6 is pressed downward, it is further pressed against the handrail column 9 and the draining material 4.

The sealing step S4 is a step of filling the sealing material 10 between the pressing material 8 and the handrail support column 9. In this step S4, with the handrail support 9 penetrating the insertion hole 43, the sealing material 10 is filled between the pressing material 8 and the handrail support 9 from above via the insertion hole 43. A watertight material holding tool 6 and a watertight material 5 are arranged at the bottom between the pressing material 8 and the handrail column 9 where the sealing material 10 is filled, and the watertight material holding tool 6 is the pressing material 8. The watertight material 5 is pressed against the handrail support 9 while being pressed by the handrail. Therefore, the sealing material 10 is filled in a groove having a substantially rectangular frame shape in a plan view with the pressing material 8 and the handrail support 9 as side portions and the watertight material holding tool 6 and the watertight material 5 as bottom portions.

In the case of this embodiment, the watertight material retainer 6 is provided on the upper surface of the draining material 4 so as to come into contact with the watertight material 5 in a state where the handrail support 9 penetrates through the through hole 36. At this time, the holding portion 38 of the watertight material holding tool 6 elastically deforms so as to stand up in contact with the watertight material 5, and presses the watertight material 5 against the outer surface of the handrail column 9 and the upper surface of the draining material 4. Therefore, it is possible to prevent water from entering the inside of the rising portion 3 (the space between the face material 14 and the base member 13) through the through hole 33 of the draining material 4. In addition to this, in the case of this embodiment, the lower cap wood 7 is provided with a pressing material 8 for pressing the watertight material holding tool 6 downward. Therefore, by providing the lower cap wood 7 on the draining material 4, the pressing member 8 presses the pressing portion 38 of the watertight material holding tool 6 downward, so that the watertight material 5 is strongly pressed against the handrail support 9 and the draining material 4. Can be pressed against.

Further, in the case of the present embodiment, since the pressing member 8 is formed of an elastic material that can be elastically deformed, the pressing member 38 of the watertight material pressing tool 6 is lowered while being elastically deformed in contact with the watertight material pressing tool 6. Press to. Therefore, the watertight material 5 can be strongly pressed against the handrail column 9 and the drainer material 4. Further, in the case of the present embodiment, the watertight material 5 and the watertight material retainer 6 are not exposed to the outside by the lower cap wood 7 or the like, and the appearance of the handrail is not spoiled.

Further, in the case of this embodiment, the through hole 36 of the watertight material retainer 6 has an area larger than the horizontal cross-sectional shape of the handrail support 9. Therefore, when the watertight material 5 is pressed by the watertight material holding tool 6, the elastically deformed watertight material 5 is sandwiched between the tip of the holding portion 38 and the outer peripheral surface of the handrail support column 9. As a result, the watertight material 5 can be pressed more strongly against the handrail column 9 by the watertight material retainer 6. Further, in the case of this embodiment, since the through hole 36 of the watertight material holding tool 6 has an area larger than the horizontal cross-sectional shape of the handrail support 9, when the watertight material holding tool 6 is installed, the holding portion 38 A gap can be formed between the tip end portion of the handrail and the outer peripheral surface of the handrail support column 9. Therefore, the watertight material retainer 6 can be easily installed so that the tip of the retainer 38 does not come into contact with the outer peripheral surface of the handrail column 9, and damage to the handrail column 9 can be prevented.

Further, in the case of this embodiment, double-sided tape 39 is not provided at both front and rear ends of the watertight material retainer 6. Therefore, when the watertight material retainer 6 is adhered to the waste drainer 4, a gap is formed between the front end of the watertight material retainer 6 and the drainer 4 to open forward, and the watertight material retainer 6 is formed. A gap that opens rearward is formed between the rear end portion and the drainer drainer 4. As a result, even if water enters between the watertight material retainer 6 and the waste drainer 4, it can be discharged to the outside through both openings.

Further, in the case of this embodiment, in addition to the watertight material 5 preventing water from entering the rising portion 3, the sealing material 10 prevents the water from entering the rising portion 3, so that the water can be prevented from entering the rising portion 3. It can be prevented more reliably. Further, in the case of this embodiment, since the pressing material 8 serves as a backup material when filling the sealing material 10, it is not necessary to separately provide a backup material, and a simple configuration can be achieved.

Further, in the case of this embodiment, the draining arrangement step S1, the holding tool arrangement step S2, the lower cap tree arrangement step S3, and the sealing step S4 are sequentially executed. Therefore, it is possible to easily construct the waterproof structure 1 in which the watertight material 5 prevents water from entering and the sealing material 10 prevents water from entering.

The present invention is not limited to the configuration of the above embodiment, and can be appropriately modified without departing from the scope of the idea of the present invention.
