In this embodiment, the shape of the cylindrical cover 21 is cylindrical, and the upper side of the inner wall side (right side in FIG. 2A) of the cylindrical cover 21 is longer than the lower side.

  As shown in FIG. 2A, the water shielding ring wall portion 22 is formed so as to protrude from the outer periphery of the cylindrical cover 21 on the inner wall side (right side) of the cylindrical cover 21. It is possible to prevent the poured water droplets from entering the inner wall side. Specifically, water drops poured from above the cylindrical cover 21 and from the outer wall side (left side) of the cylindrical cover 21 flow to the inner wall side (right side) of the cylindrical cover 21 beyond the water shielding ring wall portion 22. It can be prevented.

  In this embodiment, as shown in FIG. 2A, the impermeable ring wall portion 22 is arranged from the outer wall side to the inner wall side (from the left side to the right side) of the cylindrical cover 21 as it goes upward from the lower end portion. It is formed so as to be inclined obliquely, and water droplets poured into the water shielding ring wall portion 22 flow to the outer wall side of the cylindrical cover 21. Further, the water-impervious ring wall portion 22 is arranged on the inner wall side with respect to the waterproof layer 35 on the upper end side, and is formed in a ring shape over the entire circumference of the cylindrical cover 21.

  The water passage 23 is disposed below the cylindrical cover 21 as shown in FIG. In the present embodiment, the water passage 23 is formed by a passage wall 25 disposed so as to cover the lower side in the circumferential direction of the cylindrical cover 21, and the passage wall 25 is integrated with the water-impervious ring wall portion 22.

  The water passage 23 has a function as a water droplet receiving portion for receiving water droplets poured on the outer peripheral surface from the outer wall side end portion of the cylindrical cover 21 to the water shielding ring wall portion 22, and It functions as a passage through which water flows on the outer wall side (left side in FIG. 2A). A drain outlet 26 is formed at the outer wall side end of the water passage 23 (left end in FIG. 2A) for discharging water droplets further outward than the outer wall side end. The drain port 26 is formed so as to protrude from the outer frame body 24.

  In the outer wall side end (left end) of the sleeve 10 having the above-described configuration, a gap formed by the sleeve main body 11, the outer frame body 24, and the outer wall 31 is filled with, for example, a caulking 42. In addition, a gap between the sleeve main body 11 and the inner wall 33 is filled with a packing 41 at the inner wall side end (right end) of the sleeve 10. In this way, water or the like cannot enter from the outside of the wall 30.

Below, the manufacturing method of the drainage member 20 for sleeves, and the construction method of the sleeve 10 are demonstrated.
As shown in FIG. 3, the sleeve drain member 20 can be engaged with the cylindrical cover 21, a member in which the cylindrical cover 21, the water-impervious ring wall portion 22, the passage wall 25, and the drain port 26 are integrally formed. It is manufactured by engaging the outer frame body 24 having the engagement portion 24a provided in the hole and having the hole 27 formed therein.

More specifically, as shown in FIG. 4, the engaging portion 24 a of the outer frame body 24 is engaged with and fixed to the inside of the cylindrical cover 21 of the sleeve drain member 20. As shown in FIG. 5, a fitting portion 24 b that can be fitted inside the cylindrical cover 21 is formed in the outer frame body 24, and the fitting portion 24 b of the outer frame body 24 is fitted inside the cylindrical cover 21. You may make it do.
Furthermore, in this embodiment, the water-impervious ring wall portion 22 protrudes from the outer periphery of the cylindrical cover 21, and further protrudes in the direction perpendicular to the radial direction of the cylindrical cover 21 and toward the outer wall side of the cylindrical cover 21.

Next, the construction method of the sleeve 10 will be described with reference to FIG.
As shown in FIG. 6A, the wall 30 includes an outer wall 31, an intermediate wall 32, and an inner wall 33, and a heat insulating material 34 is provided between the intermediate wall 32 and the inner wall 33. A waterproof layer 35 is formed on the outer wall side. A through hole 36 penetrating the wall 30 is formed in the wall 30 as shown in FIG.

Next, as shown in FIG. 6C, the sleeve body 11 is disposed in the through hole 36. Here, a packing 41 is disposed at the inner wall side end (right end) of the through hole 36 so as to fill a gap between the through hole 36 and the inner wall 33.
Then, as shown in FIG. 6D, the sleeve drainage member 20 is mounted at a predetermined position from the outer wall side (left side) of the sleeve body 11. Then, a gap between the sleeve drain member 20 and the outer wall 31 is filled by the caulking 42. At this time, at least a part of the impermeable ring wall portion 22 is arranged inside the hole of the heat insulating material 34.
As described above, the construction of the sleeve 10 is completed.

In the sleeve drainage member 20, the sleeve 10, and the sleeve wall penetrating structure 1 according to the embodiment of the present invention configured as described above, it is caused by water droplets entering the inside of the wall 30 from the outer wall 31 or internal condensation. The water droplets thus generated are poured onto the outer peripheral surface from the outer wall side end portion of the cylindrical cover 21 to the water shielding ring wall portion 22. And the water droplet which flows into the impermeable ring wall part 22 flows into the water passage 23, and can be paid out from the drain outlet 26 of the water passage 23 to the outside of the wall 30.
Specifically, as shown in FIGS. 7A and 7B, the water droplet X flowing through the water-impervious ring wall portion 22 moves to the outer wall side of the water-impervious ring wall portion 22 (left side in FIG. 7A). And further flows into the water passage 23. Then, the water droplets X accumulated in the water passage 23 are discharged from the drain port 26 to the outside of the wall 30.

  When the through-hole 36 is formed in the wall 30, an opening is formed in the waterproof layer 35, and there is a possibility that water droplets may enter the heat insulating material 34 through this opening. By providing the drainage member 20 for use, water can be prevented from entering the heat insulating material 34. Therefore, it is possible to maintain the heat insulating performance of the heat insulating material 34 over a long period of time. Moreover, the corrosion which arises in the inner wall 33 can be suppressed by suppressing the permeation of water to the inner wall side.

Further, in the present embodiment, the water shielding ring wall portion 22 is formed so as to be inclined obliquely so as to be arranged from the outer wall side to the inner wall side of the cylindrical cover 21 as it goes upward from the lower end portion. Water can be efficiently flowed from the inner wall side to the outer wall side with water drops poured on the outer periphery of 21.
Therefore, when the sleeve drainage member 20 is attached to the sleeve 10, water drops poured into the cylindrical cover 21 can be efficiently guided to the outer wall side, and the water drops can be discharged from the water passage 23 to the outer wall side.

  Further, since the water passage 23 is formed by a passage wall 25 provided so as to cover the lower side of the sleeve 10, when water drops drop on the water passage 23, the water splashes and falls downward. Can be prevented, and water can be reliably discharged from the water passage 23.

  Furthermore, since the water passage 23 is formed with a drain outlet 26 for discharging water droplets to the outside of the wall 30, the water droplets can be efficiently discharged from the water passage 23.

  As mentioned above, although the drainage member for sleeves and the sleeve which are one Embodiment of this invention were demonstrated, this invention is not limited to this, In the range which does not deviate from the technical idea of the invention, it can change suitably.

  In the above-described embodiment, the water-impervious ring wall portion 22 is obliquely formed so as to be arranged from the outer wall side to the inner wall side of the cylindrical cover 21 as it goes upward from the lower end portion in a side view. However, as shown in FIG. 8, the water-impervious ring wall portion 122 extends from the outer periphery along the circumferential direction (vertical direction in FIG. 8) of the sleeve body 11 inside the hole of the heat insulating material 34. It is good also as the sleeve 110 and the drainage member 120 for sleeves which were formed protrudingly. In this case, the water passage 123 is formed by connecting the passage wall 125 to the water-impervious ring wall 122, and water drops flow through the water-impervious ring wall 122, and further flow through the water passage 123 to the wall. It is paid out to the outside of 30. That is, the impermeable ring wall portion has a shape having a function as a wall that prevents a water droplet entering from the opening of the waterproof layer from entering the inner wall side (right side in FIG. 8) from the impermeable ring wall portion. It ’s fine.

  In the above embodiment, the case where the sleeve drain member is assembled to the sleeve main body has been described. However, the sleeve main body and the sleeve drain member may be integrally formed. That is, the sleeve is provided at the intermediate portion between the sleeve main body, the outer wall side end portion and the inner wall side end portion of the sleeve main body, and is formed so as to protrude from the outer periphery of the sleeve main body. A water passage that is provided on the outer periphery and discharges water droplets poured onto the outer peripheral surface from the outer wall side end of the sleeve body to the water shielding ring wall to the outer wall side may be provided.

In this case, the water-impervious ring wall portion may be formed obliquely so as to be arranged from the outer wall side to the inner wall side of the sleeve body as it goes upward from the lower end portion. Further, the water passage may be formed by a passage wall provided so as to cover the lower side of the sleeve body. The water passage may be formed with a drain outlet for discharging water droplets outward from the outer wall side end of the sleeve body.
Even in the sleeve including the sleeve main body, the water-impervious ring wall portion, and the water passage as described above, it is possible to obtain the same effect as the sleeve of the above-described embodiment.

Moreover, in the said embodiment, although the case where the drain outlet was formed in the water channel was demonstrated, the drain outlet does not need to be formed.
Moreover, in the said embodiment, although the case where the outer frame body was provided in the outer wall side of a cylindrical cover was demonstrated, the outer frame body does not need to be provided.
In addition, a lid may be provided on the outer wall side end portion and the inner wall side end portion of the sleeve.

  The material of the drainage member for sleeve is not particularly limited, but is preferably composed of hard or soft synthetic resin or rubber. In particular, when it is made of soft synthetic resin or rubber, the watertightness is good when the sleeve drainage member is assembled to the existing sleeve body.

  In the above embodiment, the case where the sleeve of the present embodiment is arranged in the through hole formed in the wall of the building when installing an air conditioner or a cooler has been described. However, it is necessary to prevent penetration of water. The present invention can be applied to the holes.
