FIG. 2 is an exploded perspective view of members disposed on the side of the outdoor plate 15 that is the first plate from the main body 19 of the wall portion penetrating member 2. The wall portion penetrating member 2 mainly includes an outdoor plate 15, a guide plate 25, a main body 19, a screw 7, a locking portion 17, a rotation restricting member 5, and the like. The wall penetrating member 2 is provided so as to sandwich the main body 19 between the outdoor plate 15 and the guide plate 25.

  For the outdoor plate 15 and the guide plate 25, for example, a corrosion-resistant metal such as stainless steel or aluminum can be used, and a resin or the like can be used if it has a certain level of strength.

  The main body 19 is made of, for example, silicone rubber or ethylene propylene rubber. The main body 19 has a tubular pipe holding portion 6 that can hold pipes on the surface on the outdoor plate 15 side. The main body 19 has a recess on the back side of the surface on which the pipe holding portion 6 is formed. A pressing plate 21 is fixed to the concave portion of the main body 19 when the wall penetrating member 2 is assembled.

  Screws 7 are inserted through the outdoor plate 15, the main body 19, the pressing plate 21 and the guide plate 25. The head of the screw 7 is disposed on the surface of the outdoor plate 15, the O-ring 4 is sandwiched between the head of the screw 7 and the outdoor plate 15, and the axis of the screw 7 penetrates the outdoor plate 15.

  Further, the shaft of the screw 7 is inserted through the main body 19, the holding plate 21 and the guide plate 25 in order. The wall penetrating member 2 is fixed by screws 7. A rotation restricting member 5 that is a screw-like member is disposed in the vicinity of the screw 7.

  Next, the relationship between the position and function of the screw 7 and the rotation restricting member 5 will be described. The shaft of the screw 7 protrudes from the guide plate 25. The locking portion 17 is screwed into a portion protruding from the guide plate 25 of the shaft of the screw 7. The locking part 17 is a plate-like member. As described above, the rotation restricting member 5 exists in the vicinity of the shaft of the screw 7. When the screw 7 is rotated from the outdoor plate 15 side, the locking portion 17 rotates together with the screw 7 until it contacts the rotation restricting member 5. When the locking portion 17 comes into contact with the rotation restricting member 5, the locking portion 17 moves in the axial direction of the screw 7 as the screw 7 rotates.

  A tube 23 is provided on the shaft of the screw 7 between the guide plate 25 and the locking portion 17. The tube 23 is a member (for example, a rubber member or a spring) that has the same or slightly smaller inner diameter than the outer diameter of the shaft of the screw 7 and can be elastically deformed. That is, the tube 23 is in close contact with the axis of the screw 7, and the tube 23 does not rotate with respect to the axis of the screw 7. The locking portion 17 is in contact with the tube 23 in a state where it is screwed with the screw 7. Accordingly, when the screw 7 is rotated, the locking portion 17 rotates together with the screw 7 due to friction with the tube 23, and when installed on the wall portion, the locking portion 17 projects substantially parallel to the wall portion on the outer peripheral side of the guide plate 25, It is possible to sandwich the wall.

That is, since the wall part penetrating member 2 is fixed to the wall part 3 by tightening the screw 7 only from one surface of the wall part penetrating member 2, attachment is easy.

  Further, the main body 19 can be securely sandwiched between the outdoor plate 15 and the guide plate 25. Therefore, the water tightness of the pipe 33 and the main body 19 is maintained. Further, the water tightness of both the wall surfaces separated by the wall portion 3 and the main body 19 is maintained. Therefore, the water stop performance of the wall portion penetrating member 2 is reliably exhibited.

  Further, by sandwiching the main body 19 between the outdoor plate 15 and the guide plate 25, the main body 19 can be held without being deformed by bending or the like even if the pipe holding portion 6 and the pipe 33 are bent.

  Further, by sandwiching the main body 19 between the guide plate 25 and the outdoor plate 15, the rotation restricting member 5 does not move even if the guide plate 25 receives pressure from the locking portion 17 when the wall portion penetrating member 2 is attached to the wall portion 3. Since it can prevent falling, the wall part penetration member 2 can be attached to the wall part 3 reliably.

  Further, since the tube 23 is provided on the shaft of the screw 7 between the guide plate 25 and the locking portion 17, friction between the tube 23 and the locking portion 17 occurs. For this reason, the locking part 17 can be rotated together with the screw 7. Therefore, by providing the tube 23, it is possible to prevent the locking portion 17 from spinning around when the screw 7 is rotated.

  Moreover, when the water-expandable nonwoven fabric 11 absorbs moisture or the like and expands, the guide plate 25 presses the water stop structure toward the outdoor plate 15, and the holding member 13 presses the water stop structure against the wall 3. Therefore, even if it is a simple structure, it can stop water more reliably. In addition, since the wall portion penetrating member 2 includes the holding member 13, it is possible to prevent the main body 19 from being deformed inward, so that the wall portion penetrating member 2 can be more reliably fixed to the wall portion 3.

  In addition, since the screw 7 sandwiches the O-ring 4 between the head of the screw 7 and the outdoor plate 15, the outdoor plate 15 is disposed outside the building or the like and installed in a place where moisture or the like may enter, The water blocking property of the wall penetrating member 2 is maintained.

  Moreover, according to the wall part penetration structure 1, since the wall part 3 is pinched | interposed by the latching | locking part 17 projecting to the outdoor plate 25 and the outer peripheral side by rotating the screw 7 from one surface, the wall part 3 is easy. The wall part penetrating member 2 can be fixed to the wall part 3 and the pipe 33 can be inserted into the wall part 3. In addition, since the structure is simple, the degree of freedom in installation is high.

  Moreover, the water tightness of a pipe holding part and a corrugated pipe is maintained by sticking the pipe holding part 6, the pipe 33, and the corrugated pipe 31.

Next, the wall part penetration member 2a concerning the 2nd Embodiment of this invention is demonstrated.
In addition, in the following embodiment, about the structure which show | plays the same function as the wall part penetration structure 1, the code | symbol same as FIGS. 1-6 is attached | subjected and the overlapping description is abbreviate | omitted.

  FIG. 7 is a perspective view showing a wall portion penetrating member 2a according to the second embodiment. The wall portion penetrating member 2a is, for example, a resin pipe. The wall part penetrating member 2a is used as, for example, a penetrating pipe when an air conditioner is installed indoors. In the first embodiment, the pipe 33 is inserted through the wall penetrating member 2, but the present embodiment differs in that the wall penetrating member 2a itself constitutes the pipe.

  The main body sandwiched between the outdoor plate 15a as the first plate and the guide plate 25a as the second plate has a cylindrical portion that is substantially perpendicular to the outdoor plate 15a and the guide plate 25a in the present embodiment. The main body including the cylindrical portion is referred to as a pipe 37.

  The outdoor plate 15a and the guide plate 25a have a hole in the central portion. Each hole of the outdoor plate 15a and the guide plate 25a is larger than the hole in the cross section of the pipe 37, and does not block the hollow portion of the pipe. That is, the wall portion penetrating member 2a itself constitutes a pipe.

  The outdoor plate 15a, the pipe 37, and the guide plate 25a are sequentially fixed by inserting and screwing screws 35 having heads on the surface of the guide plate 25a.

  For the outdoor plate 15, the guide plate 25, and the pipe, for example, a corrosion-resistant metal such as stainless steel or aluminum can be used, and a resin or the like can be used if it has a certain level of strength.

  The wall part penetrating member 2a is fixed to the wall part 3 by sandwiching the wall part 3 between the outdoor plate 15a and the locking part 17a.

  An O-ring 38 is sandwiched between the head of the screw 35 and the outdoor plate 15a, and the shaft of the screw 35 is inserted into the outdoor plate 15a. Further, the shaft of the screw 35 is inserted into the guide plate 25a and screwed to fix the wall portion penetrating member 2a. The elastic member 9a and the water-expandable nonwoven fabric 11a are sandwiched and fixed between the outdoor plate 15a and the guide plate 25a. Further, a backrest portion 39 that is a rotation restricting member is disposed in the vicinity of the screw 35.

  Next, the relationship between the position and function of the screw 35 and the backrest 39 will be described. FIG. 8 is an enlarged perspective view of the vicinity of the locking portion 17a when the wall portion penetrating member 2a is attached to the through hole 29. FIG. The shaft of the screw 35 protrudes from the guide plate 25a. In FIG. 8, a part of the screw 35 is not shown.

  A locking portion 17a is screwed into a portion of the shaft of the screw 35 protruding from the guide plate 25a. The locking part 17a is a plate-like member. As described above, the backrest portion 39 exists in the vicinity of the axis of the screw 35. When the screw 35 is rotated from the outdoor plate 15a side, the locking portion 17a rotates with the screw 35 until it comes into contact with the backrest portion 39 (A direction in the figure).

  When the locking portion 17a comes into contact with the backrest portion 39, the locking portion 17a moves in the axial direction of the screw 35 (B direction in the drawing) as the screw 35 rotates. Although the shape of the back pad 39 is a wall shape in the figure, after the locking part 17a contacts the back pad 39, the back pad 39 has a function of restricting the rotation of the locking part 17a. Just fill it.

  A tube 23a is provided on the shaft of the screw 35, and both the screw 35 and the locking portion 17a rotate due to friction between the locking portion 17a and the tube 23a. Therefore, the plate-like locking portion 17 a projects over the outer peripheral side of the through hole 29 substantially in parallel with the wall portion 3 and sandwiches the wall portion 3.

  Next, the water stop structure comprised with the elastic member 9a and the water-expandable nonwoven fabric 11a is demonstrated. FIG. 9 is an enlarged cross-sectional view of the vicinity of the pair of screws 35 and the locking portion 17 a of the wall portion penetrating member 2 a attached to the wall portion 3. An elastic member 9 a is sandwiched between the outdoor plate 15 a and the wall 3, and a water-expandable nonwoven fabric 11 a is sandwiched between the pipe 37 and the wall 3 to fix the wall penetrating member 2 a.

  Next, a procedure of a method for fixing a through pipe to the wall 3 using the wall penetrating member 2a will be described. FIG. 10 is a view showing a process of attaching the wall portion penetrating member 2a to the wall portion 3, and FIG. 10 (a) is a perspective view showing a state before the wall portion penetrating member 2a is attached to the wall portion 3, FIG. FIG. 10B is a perspective view showing a state after the wall portion penetrating member 2a is attached to the wall portion 3. FIG. 10C is a perspective view showing a state before the hood 34 is attached to the wall portion 3. FIG. FIG. 3 is a perspective view showing a state after a hood 34 is attached to the wall 3.

  First, the wall portion penetrating member is inserted into the through hole 29 formed in the wall portion 3 in a state where the locking portion 17a is directed inward of the wall portion penetrating member 2a (so that the locking portion 17 does not protrude outward). 2a is installed. The through-hole 29 should just be smaller than the outdoor plate 15a, and penetrates one wall surface and the other wall surface partitioned by the wall portion 3.

  Next, the screw 35 is rotated from the outdoor plate 15a side, the locking portion 17a is rotated until it contacts the backrest portion 39, and the locking portion 17a is directed outward of the wall portion penetrating member 2a. Further, the screw 35 is rotated, the locking portion 17a is moved to the guide plate 25 side along the axial direction of the screw 35, and the end portion of the locking portion 17a is brought into contact with the wall portion 3.

  Moreover, you may attach the hood 34 etc. to the wall part penetration member 2a fixed to the wall part 3 according to a use.

  Thus, according to the wall part penetration member 2a concerning 2nd Embodiment, when attaching the wall part penetration member 2a to the wall part 3, it is the screw | thread 35 from the surface by the side of the outdoor plate 15a of the wall part penetration member 2a. By tightening, the wall portion 3 is sandwiched between the locking portion 17a and the outdoor plate 15a disposed on the back side of the surface of the outdoor plate 15a where the screw 35 is turned. That is, since the wall part penetration member 2a is fixed to the wall part 3 by tightening the screw 35 only from one surface of the wall part penetration member 2a, attachment is easy.

  Moreover, the pipe 37 can be reliably pinched by the outdoor plate 15a and the guide plate 25a. Therefore, the water tightness of both the wall surfaces separated by the wall part 3 and the pipe 37 is maintained. Therefore, the water stop performance of the wall portion penetrating member 2a is reliably exhibited.

  In addition, the pipe 37 can be held without being deformed by sandwiching the pipe 37 between the outdoor plate 15a and the guide plate 25a.

  Further, the provision of the tube 23 a causes friction between the tube 23 a and the locking portion 17 a, so that the locking portion 17 a can rotate together with the screw 35. Therefore, by providing the tube 23a, it is possible to prevent the locking portion 17a from spinning around when the screw 35 is rotated.

  Further, when the water-expandable nonwoven fabric 11a absorbs moisture or the like and expands, the guide plate 25a presses the water-stop structure toward the outdoor plate 15a, so that the water-stop fabric can be surely stopped even with a simple structure. Can keep function.

  Further, since the screw 35 sandwiches the O-ring 38 between the head of the screw 35 and the outdoor plate 15a, the outdoor plate 15a is disposed outside the building or the like, and may be installed in a place where moisture or the like may enter.
