  Hereinafter, the wall penetration member according to the present invention will be described. FIG. 1 is a perspective view showing a wall penetrating member 1, FIG. 2 is a plan view showing the wall penetrating member 1, and FIG. 3 is a cross-sectional view taken along the line AA of FIG.

  The wall penetrating member 1 mainly includes a cylinder 3, a first flange 5, a second flange 7, a screw 9, a locking member 13, a water blocking member 15a, a water blocking member 15b, and the like. The cylindrical portion 3 is, for example, resinous, and in this case, the cylindrical portion 3, the first flange portion 5, and the second flange portion 7 are integrally configured. The wall portion penetrating member 1 may be made of metal, and the cylinder portion 3, the first flange portion 5 and the second flange portion 7 may be separately formed and joined to each other.

  A first flange portion 5 is provided on the outer peripheral surface in the vicinity of one end of the cylindrical portion 3. The first flange portion 5 protrudes outward of the cylindrical portion 3 substantially perpendicularly to the axial direction of the cylindrical portion 3 over the entire circumference. A water blocking member 15 b which is a second water blocking member is disposed on the back side of the first flange portion 5. The water blocking member 15 b is, for example, a water-expandable member or an elastic body that can closely adhere to the unevenness of the outer wall portion.

  A plurality of through holes are formed in the first flange portion 5 at predetermined intervals in the circumferential direction. The screw 9 is inserted through the hole. That is, the screw 9 penetrates from the front of the first flange portion 5. In the rear of the first flange portion 5, a thick portion 8 which has an outer diameter smaller than that of the first flange portion 5 and which is expanded so as to include the screw 9 is provided. As described above, by increasing the length of the hole, the screw 9 can be prevented from being inclined or shifted. In the example illustrated in FIG. 1, the screws 9 are disposed at three locations in the circumferential direction, but may be at least two locations or more, and the number of dispositions is not limited.

  At the rear of the first flange portion 5, the idling prevention member 11 is disposed on the outer periphery of the screw 9. The idling prevention member 11 is a ring-shaped elastic member such as an O-ring. Further, a locking member 13 screwed with the screw 9 is provided further to the rear of the idling prevention member 11.

  The idling prevention member 11 is a member that prevents the locking member 13 from idling with respect to the screw 9. In a normal state, the locking member 13 is folded so as to contact the cylindrical portion 3 without projecting from the projection surface of the first flange portion 5 in a front view. Further, the idling prevention member 11 is disposed at a position separated by a predetermined distance from the back surface of the first flange portion 5, and the locking member 13 is disposed at the rear thereof. The operation of the locking member 13 will be described in detail later.

  A second flange portion 7 is provided on the outer peripheral surface of the cylindrical portion 3 at a position separated by a predetermined distance from the first flange portion 5 and at the rear of the locking member 13. The second flange portion 7 protrudes outward of the cylindrical portion 3 substantially perpendicularly to the axial direction of the cylindrical portion 3 over the entire circumference, and has an outer diameter smaller than that of the first flange portion 5.

  A water blocking member 15a, which is a first water blocking member, is disposed on the back surface side of the second flange portion 7 (the opposite side to the first flange portion 5). The water blocking member 15a is preferably an elastic body or a water expandable member, and is, for example, a urethane foam.

  Further, in the vicinity of the locking member 13, a rib 17 is provided on the outer surface of the cylindrical portion 3 between the thick portion 8 and the second flange portion 7 along the axial direction of the cylindrical portion 3. The rib 17 is disposed in the vicinity of the screw 9 and has a larger outer diameter than other portions (for example, the outer surface of the cylindrical portion 3 in the screw 9). The height (radius) of the rib 17 is substantially equal to the height (radius) of the second flange portion 7. That is, the rib 17 does not protrude outward beyond the second flange portion 7. The shape of the rib 17 is not particularly limited as long as it can be disposed along the screw 9 and to the outside of the cylindrical portion 3, and another member may be disposed instead of the rib 17.

  Next, a method of fixing the wall penetrating member 1 will be described. FIG. 4 is a view showing a state in which the wall penetrating member 1 is inserted into the wall 19. The wall portion 19 includes an outer wall portion 19a disposed on the outdoor side, a wood board 19b disposed on the indoor side, and a moisture permeable waterproof sheet 19c attached to the surface of the wood board 19b. The outer wall portion 19a and the wood board 19b are disposed apart from each other. The wood board 19b is, for example, plywood.

  The wall 19 is provided with a through hole in advance. More specifically, a through hole 21a which is a first through hole is formed in the outer wall 19a, and a through hole 21b which is a second through hole is provided in the wood board 19b (the moisture permeable waterproof sheet 19c). . The through holes 21a and 21b are formed on the same axis, and the through hole 21b has a diameter smaller than that of the through hole 21a.

  Here, the outer diameter of the second flange portion 7 is smaller than the inner diameter of the through hole 21 a provided in the outer wall portion 19 a. Therefore, when the wall portion penetrating member 1 is inserted from the outer wall portion 19a side, the second flange portion 7 can pass through the through hole 21a. On the other hand, the outer diameter of the first flange portion 5 is larger than the inner diameter of the through hole 21a. Therefore, the wall penetrating member 1 can be inserted until the first flange 5 (water blocking member 15b) contacts the outer surface of the outer wall 19a. The outer diameter of the second flange portion 7 is larger than the inner diameter of the through hole 21 b. For this reason, the second flange portion 7 is not inserted into the through hole 21b.

  First, as described above, in a state where the locking member 13 falls along the outer peripheral surface of the cylindrical portion 3, the cylindrical portion 3 is inserted into the through hole 21a from the outside of the outer wall 19a. At this time, the tip of the cylindrical portion 3 is inserted into the through hole 21 b. As described above, when the wall portion penetrating member 1 is inserted until the water blocking member 15b contacts the outer surface around the through hole 21a of the outer wall 19a, the water blocking member 15a is on the outer surface side of the through hole 21b ( It can be inserted to such an extent as to substantially contact the moisture permeable waterproof sheet 19c). That is, the distance between the back surface of the water blocking member 15a and the back surface side of the water blocking member 15b is approximately the same as the distance between the outer surface side of the wood board 19b (moisture permeable waterproof sheet 19c) and the outer surface of the outer wall 19a.

  Next, the screw 9 is rotated from the front of the first flange portion 5. Fig.5 (a) is the elements on larger scale of the latching member 13 vicinity in the BB line | wire cross section of FIG. As described above, when the wall portion penetrating member 1 is inserted into the wall portion 19, the locking member 13 falls down along the outer peripheral surface of the cylindrical portion 3. For example, the locking member 13 does not protrude outward from the circumscribed circle including the rib 17 described above, and when the cylindrical portion 3 is inserted into the through hole 21a, the locking member 13 and the outer wall portion 19a There is no interference.

  When the screw 9 is rotated from the front surface side (the first flange 5 side) of the outer wall 19a, the locking member 13 rotates with respect to the screw 9 until the locking member 13 contacts the idle rotation preventing member 11 with the rotation of the screw 9. It rotates and moves to the outer wall 19a side. At this time, since the friction at the screwing portion between the locking member 13 and the screw 9 is smaller than the weight of the locking member 13, the locking member 13 does not rotate and moves along the cylindrical portion 3. Therefore, as shown in FIG. 5 (a), the locking member 13 maintains the folded state.

  When the screw 9 is further rotated and the locking member 13 contacts the idling prevention member 11, the locking member 13 receives resistance by the idling prevention member 11, as shown in FIG. 5 (b). That is, the movement in the direction of the outer wall portion 19 a is resisted by the idling prevention member 11, and the rotation of the locking member 13 with respect to the screw 9 is restricted. Therefore, as shown in FIG. 5B, the locking member 13 rotates with the screw 9 (in the direction of the arrow C in the figure).

  At this time, the locking member 13 can rotate until a portion of the locking member 13 contacts the outer peripheral surface of the cylindrical portion 3 (the rib 17 formed on the outer peripheral surface of the cylindrical portion 3). That is, the rib 17 functions as a rotation restricting portion. When the locking member 13 is completely rotated, the tip of the locking member 13 spreads outward and protrudes outward beyond the first flange portion 5 in a front view. That is, as shown to Fig.6 (a), the securing member 13 protrudes on the outer peripheral side of the through-hole 21a.

  When the screw 9 is further rotated, the locking member 13 comes in contact with the rib 17 (the cylindrical portion 3) and can not be rotated any more. Therefore, as shown in FIG. It moves to the outer wall 19 a side (the first flange 5 side) along the axial direction of the screw 9 together with the idle rotation preventing member 11 (in the direction of the arrow D in the figure). When a part of the locking member 13 contacts the inner surface of the outer wall 19a, the outer wall 19a is sandwiched between the locking member 13 and the first flange 5 via the water blocking member 15b.

  When the screw 9 is further screwed in, as shown in FIG. 7, the cylindrical portion 3 of the wall portion penetrating member 1 is pushed into the room (in the direction of arrow E in the drawing). For this reason, the water blocking member 15b provided on the back surface of the first flange portion 5 is pressed against the front surface of the outer wall 19a. That is, the water blocking member 15b is deformed, and the water blocking member 15b is in close contact with the front surface of the outer wall portion 19a and is stopped. At this time, the water blocking member 15a provided on the back surface of the second flange portion 7 is pressed against the front surface of the wood board 19b (moisture permeable waterproof sheet 19c). That is, the water blocking member 15a is deformed and closely attached to the front surface of the wood board 19b (the moisture permeable waterproof sheet 19c).

  By performing the above-described operation on all the screws 9, the wall penetrating member 1 (water blocking member 15a etc.) is fixed to the wall 19, and as shown in FIG. The fixing structure 20 to the part 19 can be obtained. Thereafter, the installation is completed by inserting a pipe or the like into the wall portion penetrating member 1.

  As described above, according to the present embodiment, when attaching the wall penetrating member 1 to the wall 19, the wall penetrating member is fixed to the wall 19 by tightening the screw 9 from the front side of the wall 19. 1 is fixed. For this reason, it is not necessary to work with the front surface and the rear surface of the wall 19, and the mounting is easy. In particular, the waterproofness between the internal wood board 19b (the moisture permeable waterproof sheet 19c) and the wall portion penetrating member 1 can be secured without removing the outer wall portion 19a, so that it is easy to the wooden structure. It can be fixed to

  Moreover, the locking member 13 can be reliably rotated outward by providing the idle rotation preventing member 11. When the wall penetrating member 1 is removed, when the screw 9 is reversely rotated, the locking member 13 rotates in a folded state and moves rearward. After the wall portion penetrating member 1 is taken out of the wall portion 19, the position of the idling prevention member 11 can be returned to the original position, and can be used again.

  Next, a second embodiment will be described. FIG. 8 is a view showing the fixing structure 20 a in which the wall penetrating member is fixed to the wall 19. In the following description, components having the same functions as those of the fixed structure 20 are denoted by the same reference numerals as in FIGS. 1 to 7, and redundant description will be omitted.

  In the present embodiment, the water blocking member 15 b is not provided on the back surface side of the first flange portion 5. That is, the outer wall portion 19 a is directly sandwiched between the first flange portion 5 and the locking member 13. In this state, the water blocking member 15a provided on the back surface of the second flange portion 7 is pressed against the front surface of the wood board 19b (the moisture permeable waterproof sheet 19c). That is, the water blocking member 15a is deformed and closely attached to the front surface of the wood board 19b (the moisture permeable waterproof sheet 19c).

  From this state, the seal member 23 is provided on the outer peripheral portion of the first flange portion 5. The seal member 23 is, for example, a caulking material. By fixing the caulking material, it is possible to obtain the fixing structure 20 a to the wall 19 of the wall penetrating member.

  According to the second embodiment, the same effect as that of the first embodiment can be obtained. Thus, since water blocking of the outer wall 19a and the first flange 5 can be performed from the outer surface side of the outer wall 19a, even if a conventional caulking material is used instead of the water blocking member 15b. Good.

  Although the embodiments of the present invention have been described above with reference to the attached drawings, the technical scope of the present invention is not influenced by the embodiments described above. It is apparent that those skilled in the art can conceive of various changes or modifications within the scope of the technical idea described in the claims, and they are naturally also within the technical scope of the present invention. It is understood that it belongs.
