  Further, the other joint 502 of the joints 5 and 5 connected to the respective ends of the first fluid pipe 201 is an elbow, like the one joint 501, as shown in FIG. The end side is the first connection port 6, and the other end side is the second connection port 7. And the 1st connection port 6 and the 2nd connection port 7 in this other joint 502 are the same structures as one joint 501, and the other joint 502 is similar to one joint 501, and joint body 5a. And a ring body 6d constituting the first connection port 6. However, unlike the one joint 501, the bent portion 8a of the intermediate portion 8 is simply curved in an arc shape without bulging to the opposite side of the second connection port 7. And the intermediate part 8 has the straight part 8b on the 1st connection port 6 side and the 2nd connection port 7 side other than this bending part 8a.

  Also, in this other joint 502, the ring body 9 is fitted to the outer periphery of the end portion of the second fluid pipe 202. This ring body 9 is similar to the one joint 501 in the second connection port 7 and the other. It is not a member constituting the joint 502.

  By the way, the wall penetration structure 3 accommodates the 2nd connection port 7 (specifically, the 2nd connection port 7 and the 2nd connection port 7 side in the intermediate part 8) in each wall surface, as shown in FIG. A protective cover 10 is provided. The protective cover 10 includes a plate-like base 11 that is arranged along the wall surface 1b and is fixed to the wall surface 1b, and a cover 12 that is attached to the base 11.

Here, each of the protective covers 10 and 10 is formed with a through hole 11a in the base 11 that communicates with the through hole 1a and through which the joint 5 (501, 502) penetrates. And these through-holes 11a and 11a are in the state where the 1st connection port 6 of the said one coupling 501 faced the front-and-back direction of the base 11 (namely, the penetration direction of the through-hole 1a). It has a size that allows it to pass.

  Further, the straight cover 13 is provided along the wall surface 1b so as to be connected to the protective cover 10. The second fluid pipe 202 is housed in the protective cover 10 and the straight cover 13.

  Next, the effects of the wall penetration structure 3 (including the wall penetration member 4 and the joint 5) of the fluid pipe 2 having the above configuration and the wall penetration method of the fluid pipe 2 will be described.

  In the wall penetration structure 3 of the fluid pipe 2, the first fluid pipe 201 is piped in the through hole 1 a of the wall 1, and the second fluid pipes 202 and 202 are piped along the both wall surfaces 1 b and 1 b. The joints 5 and 5 are provided between the first fluid pipe 201 and the second fluid pipes 202 and 202. At least one of the joints 5 and 5 501 (in the illustrated embodiment, one of the joints 5 and 5 501) is connected to the end of the first fluid pipe 201. A bent portion 8a of the intermediate portion 8 that connects the connection port 6 and the second connection port 7 to which the end of the second fluid pipe 202 is connected bulges to the opposite side of the second connection port 7 and curves. By being formed, the second connection port 7 is brought closer to the axis 6a side of the first connection port 6, and one of the joints 501 is in a state where the first connection port 6 faces the penetrating direction of the through hole 1a. The size is such that it can be inserted into the through hole 1a. That is, the bent portion 8a bulges to the opposite side of the second connection port 7 and is curved so that the second connection port 7 is brought closer to the axis 6a side of the first connection port 6. The projected area of the one joint 501 in the direction of the axis 6a of the first connection port 6 can be reduced, and by reducing the projected area of the one joint 501 in this way, the one joint 501 can be reduced. Can be sized such that the first connection port 6 can be inserted into the through hole 1a with the first connection port 6 facing the through direction of the through hole 1a. And by setting one joint 501 to such a size, the joint 5 (501, 502) is connected to each end portion of the first fluid pipe 201 outside the through hole 1a, and the wall penetrating member 4 is attached. The wall penetrating member 4 can be formed and inserted into the through hole 1a from the side of the one joint 501. In addition, it is not necessary to enlarge the through hole 1a.

  And also in the wall penetration method of the fluid pipe 2, the wall penetration member 4 in which the joint 5 (501, 502) is connected to each end of the first fluid pipe 201 is inserted into the through hole 1a from one joint 501 side. However, it is not necessary to enlarge the through hole 1a for this insertion.

  Therefore, according to the wall penetration structure 3 (including the wall penetration member 4 and the joint 5) and the wall penetration method, the joints 5 and 5 can be connected to both ends of the first fluid pipe 201 outside the through hole 1a. Since it can do, the connection operation | work of the 1st fluid pipe | tube 201 and the couplings 5 and 5 becomes easy, and the connection confirmation can be performed.

  Further, when one joint 501 brings the second connection port 7 closer to the axial center 6a side of the first connection port 6, the bent portion 8a is in a direction opposite to the second connection port 7 and facing the opposite side. The first connection port 6 bulges to the same position as the end 6b and is curved. Thereby, while suppressing the amount of bulging of the bent portion 8a, the projected area in the direction of the axis 6a of the first connection port 6 in this one joint 501 can be made sufficiently small. From this point of view, the same position as the end 6b does not mean that the end 6b is completely coincident, and may be a position that can be substantially regarded as the position.

  In the illustrated embodiment, a protective cover 10 is provided on each wall surface. And since the through-hole 11a provided in the base 11 of this protective cover 10 is a magnitude | size which one joint 501 can pass, after this base 11 and 11 is arrange | positioned to both wall surface 1b, 1b, The wall penetrating member 4 in which the joint 5 (501, 502) is connected to each end of one fluid pipe 201 is connected to the through-hole 1a of the wall 1 and the through-holes 11a of the bases 11, 11 from one joint 501 side. 11a can be inserted.

  In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, when one joint 501 brings the second connection port 7 closer to the axial center 6a side of the first connection port 6, the bent portion 8a is on the opposite side of the second connection port 7 and facing the opposite side. The first connection port 6 is bulged to the same position as the end 6b of the first connection port 6, but is bulged to at least the same position as the end 6b of the first connection port 6 in the direction facing the opposite side. May be. That is, the bulge may exceed the end 6b. This also makes it possible to sufficiently reduce the projected area of the one joint 501 in the direction of the axis 6a of the first connection port 6. Further, if the projection area does not need to be so small, the bulge does not have to reach the end 6b.

  Further, the joint body 5a and the ring bodies 6d and 9 may not be made of metal but may be made of synthetic resin, or may be formed by combining these metals and synthetic resin.

  In the first connection port 6, the entire ring body 6 d is integrally formed. The ring body 6 d is divided into a split ring that fits on the outer periphery of the end of the first fluid pipe 201, and the split body. The end portion of the first fluid pipe 201 may be sandwiched between the cylindrical portion 6c and the ring body 6d composed of these two bodies by configuring the cap nut so as to reduce the diameter of the ring. This also applies to the relationship between the second connection port 7 and the second fluid pipe 202.

  Further, the first connection port 6 may be provided with, for example, a one-touch connection port at the first connection port 6 without adopting a structure in which the end portion of the first fluid pipe 201 is sandwiched between the cylindrical portion 6c and the ring body 6d. It may be adopted. That is, the first connection port 6 is provided with a retaining ring having a retaining piece that is inclined, and the first connection port 6 is connected to the first connection port 6 only by inserting the end of the first fluid pipe 201 into the first connection port 6. One fluid pipe 201 is connected. The first connection port 6 may be an adhesive connection port. This uses, for example, a vinyl chloride resin pipe as the first fluid pipe 201. By bonding the first connection port 6 to the end of the first fluid pipe 201, the first connection port 6 is used. Is connected to the first fluid pipe 201. The same applies to the relationship between the second connection port 7 and the second fluid pipe 202.

  Further, the fluid pipe 2 (201, 202) may not be made of synthetic resin but may be made of metal or the like. Further, the fluid pipe 2 (201, 202) may not be a water pipe, but may be a pipe through which other liquid or gas passes, such as a gas pipe.

  In addition, in the wall penetration structure 3 or the wall penetration member 4, the second connection ports 7 and 7 of the joints 5 and 5 may face the same direction without being directed to the opposite directions. Moreover, you may face the direction used as the position of a twist mutually.

  In addition, the other joint 502 of the joints 5 and 5 connected to each end of the first fluid pipe 201 is not an elbow, for example, the first connection port 6 is one for the second connection port 7. May be a cheese or two or more second connection ports 7 for one first connection port 6.

  As shown in FIG. 5, in the joints 5 and 5 connected to the respective ends of the first fluid pipe 201, both joints 5 and 5 connect the second connection port 7 to the axis of the first connection port 6. The bent portion 8a may bulge and bend to the opposite side to the second connection port 7 so as to approach the 6a side, and each of the joints 5 and 5 may be the one joint 501.
