In such a case, the infiltrated rainwater is guided into the hollow portion 38B of the lower floor side outer wall panel 30B by a water stop function (not shown) provided in the horizontal joint 40.

(Configuration of penetrating member)
Here, the configuration of the piping as the penetrating member according to the present embodiment will be described.

  In the present embodiment, for example, as shown in FIG. 2, the pipe 50 penetrates the outer wall panel 30. As shown in FIG. 1, the pipe 50 includes a pipe main body 52 as a penetrating member main body and a seal member 54.

  As shown in FIGS. 1 and 2, the pipe main body 52 has a cylindrical shape, and the outer diameter (outer dimension) of the pipe main body 52 is larger than the inner diameter of the through hole 56 formed in the outer wall panel 30. The pipe main body 52 can be inserted into the through hole 56. Further, as shown in FIGS. 2 and 4, a long rubber-like elastic body is used as a seal member 54 on a part of the outer peripheral surface of the pipe body 52 (a portion facing the inner edge portion 56 </ b> A of the through hole 56). EPDM sponge rubber 54A is wound a plurality of times.

  In the seal member 54, one end side along the longitudinal direction of the pipe body 52 is set so that the outer diameter dimension is smaller than the other end side of the seal member 54. Specifically, an EPDM sponge rubber 54B formed on the other end side of the seal member 54 so as to be narrower than the width of the EPDM sponge rubber 54A constituting the seal member 54 is interposed between the EPDM sponge rubbers 54A. It is wound. In FIG. 4, in order to distinguish between the EPDM sponge rubber 54A and the EPDM sponge rubber 54B, dots are put in the EPDM sponge rubber 54B.

  Thereby, the outer diameter of the other end side of the seal member 54 is larger than that of the one end side of the seal member 54. That is, the outer diameter dimension of one end side of the seal member 54 is smaller than that of the other end side of the seal member 54. The outer diameter of the seal member 54 at the other end is set to be larger than the inner diameter of the through hole 56. Preferably, the outer diameter dimension on one end side of the seal member 54 is set to be smaller than the inner diameter dimension of the through hole 56.

(Penetration member construction method)
Next, in the piping as the penetrating member according to the present embodiment, a construction method for the outer wall panel will be described.

  As shown in FIGS. 1 and 2, the seal member 54 provided on the outer peripheral surface of the pipe 50 is formed so that one end side has a smaller outer diameter than the other end side. Therefore, in the seal member 54, the pipe 50 is inserted into the through hole 56 formed in the outer wall panel 30 along the arrow A direction from the one end side toward the other end side (first step).

  Further, the outer diameter dimension at the other end side of the seal member 54 is set to be larger than the inner diameter dimension of the through hole 56. Therefore, when the pipe 50 is inserted into the through hole 56, the seal member 54 is pressed by the inner edge portion 56 </ b> A of the through hole 56 with the pipe 50 passing through the through hole 56. That is, the pipe 50 is fitted into the through hole 56 (second step). Although not shown in FIG. 2, as shown in FIG. 3, on the other end side of the seal member 54, a portion protruding beyond the inner diameter of the inner edge portion 54 </ b> A of the through hole 56 is compressed. .

  Thereby, the clearance gap between the outer peripheral surface of the piping 50 and inner edge part 56A of the through-hole 56 formed in the outer wall panel 30 is block | closed, and it will be in what is called a sealed state. In this state, the seal member 54 is disposed so as to face the inner wall portion 34 of the outer wall panel 30. Further, a joint seal backer 58 is disposed on the outer peripheral surface of the pipe body 52, and a joint seal 60 is disposed on the outdoor side of the joint seal backer 58.

(Operation and effect of penetrating member)
Next, the operation and effect of the piping as the penetrating member according to the present embodiment will be described.

  As shown in FIGS. 1 and 2, a seal member 54 is integrally provided on the outside of a pipe main body 52 constituting the pipe 50. The pipe body 52 is inserted into and penetrates the through hole 56 formed in the outer wall panel 30, and the seal member 54 is pressed into contact with the inner edge portion 56 </ b> A of the through hole 56 (the pipe 50 is fitted into the through hole 56). Like that.

  As a result, the intrusion of water between the pipe 50 and the through hole 56 is suppressed / prevented. That is, the seal member 54 closes the space between the pipe 50 and the through hole 56 of the outer wall panel 30 only by fitting the pipe 50 into the through hole 56. Thus, according to this embodiment, it is possible to seal between the pipe 50 and the through hole 56 with a simple construction.

  In the present embodiment, as shown in FIGS. 2 and 4, the other end side of the seal member 54 is formed to have a width narrower than the width of the EPDM sponge rubber 54 </ b> A constituting the seal member 54. An EPDM sponge rubber 54B is wound around the EPDM sponge rubber 54A. As a result, the outer diameter of the other end side of the seal member 54 is formed to be larger than that of the one end side of the seal member 54.

  That is, one end side of the seal member 54 is formed to have a smaller outer diameter than the other end side of the seal member 54. For this reason, as shown in FIG. 1, when the seal member 54 is inserted into the through hole 56, the insertion resistance is reduced at the distal end side in the insertion direction of the through hole 56, and can be easily inserted. Therefore, workability when attaching the pipe 50 to the outer wall panel 30 is good. Further, if the outer diameter dimension on one end side of the seal member 54 is set to be smaller than the inner diameter dimension of the through hole 56, workability is further improved.

  Further, as shown in FIGS. 1 and 4, since the seal member 54 is formed by winding long EPDM sponge rubbers 54 </ b> A and 54 </ b> B, the seal member 54 is integrally formed with the pipe 50. Cost can be reduced. Further, the outer diameter of the seal member 54 can be easily changed with respect to a dimensional error or the like in the through hole 56 by adjusting the number of windings (winding angle) of the EPDM sponge rubbers 54A and 54B.

  Further, the outer diameter of the seal member 54 can be increased by winding the narrow EPDM sponge rubber 54B around the wide EPDM sponge rubber 54A. That is, since the EPDM sponge rubber 54 </ b> A is changed and overlapped, the outer diameter of the seal member 54 can be easily changed.

  As shown in FIG. 2, the outer diameter of the seal member 54 at the other end is set to be larger than the inner diameter of the through hole 56 formed in the outer wall panel 30. For this reason, the pipe 50 is fitted into the through hole 56 in a state where the seal member 54 is pressed against the inner edge of the through hole 56. In other words, the pipe 50 is attached to the outer wall panel 30. In this state, the space between the pipe 50 and the through hole 56 is sealed, and water intrusion is prevented and suppressed between the pipe 50 and the through hole 56. . Thereby, the lifetime of the building 10 can be extended, and the user's economic burden can be reduced.

  Moreover, in this embodiment, as FIG. 2 shows, the board | plate material is formed of the outer wall panel 30 in which the hollow part 38 penetrated along a height direction was provided. A seal member 54 (secondary waterproof) is arranged on the inner wall 34 side of the outer wall panel 30 and a joint seal 60 (primary waterproof) is provided on the outer wall 32 side of the outer wall panel 30, so-called secondary waterproofing. Function can be obtained.

  Thereby, when the water (rain water) flowing through the hollow portion 38A of the upper floor side outer wall panel 30A reaches the pipe 50, it is transmitted along the circumferential direction of the outer peripheral surface of the pipe 50, and the hollow of the lower floor side outer wall panel 30B. Guided to section 38B. Therefore, it is possible to prevent water from entering the indoor side of the building 10 and to extend the life of the building 10, thereby reducing the economic burden on the user. In FIG. 2, the pipe 50 is the insertion direction, and the arrow A direction is directed from the outer wall portion 32 side to the inner wall portion 34 side of the outer wall panel 30, but conversely, from the inner wall portion 34 side to the outer wall portion 32. When the pipe 50 is inserted toward the side, the EPDM sponge rubber 54A is disposed on the insertion direction side.

  In the present embodiment, the pipe 50 connected to an air conditioner or the like has been described as the penetrating member that penetrates the outer wall panel 30, but the present invention is not limited to this. For example, the present invention may be applied to a heel that penetrates the waist wall or floor of a veranda. Further, the shape of the penetrating member is not limited to a cylindrical shape, and may be a rectangular tube shape. However, in this case, a rectangular through hole is formed in the outer wall panel. Furthermore, although not shown in the drawings, the present invention may be applied to a portion through which a square member is penetrated, such as an express beam.

  Further, in the present embodiment, as shown in FIG. 5, the example in which the extruded cement board is used as the outer wall panel 30 of the building 10 has been described. However, the outer wall may not necessarily be formed of the extruded cement board. .

  As mentioned above, although one embodiment of the present invention was described, the present invention is not limited to such an embodiment, and one embodiment and various modifications may be used in combination as appropriate, and the gist of the present invention will be described. Of course, various embodiments can be implemented without departing from the scope.
