JP 2000-199584 A

  However, the wall-penetrating structure as in Patent Document 1 has a large number of members for fixing the wall threading tool to the wall and has a complicated shape, so that the places where the wall can be installed on the wall are limited. Therefore, the use of the wall portion penetrating member is also limited.

  Moreover, since the wall threading tool of wall penetration piping like patent document 1 penetrates a sheath pipe in the inclination direction of a sheath pipe guide, and penetrates piping inside a sheath pipe, depending on an installation angle, the vertical direction of a wall threading tool The size of the is increased, and the degree of freedom of installation is low.

  The present invention has been made in view of such a problem, and provides a wall part penetrating member and a pipe wall part penetrating structure that are easy to install and have a high degree of freedom in installation.

In order to achieve the above-described object, the first invention is a wall- penetrating member that is installed in a through-hole of a wall and is used for fixing a through-pipe to the wall, comprising a metal pipe and the pipe A metal flange member joined to the outer peripheral surface of the portion, a screw penetrating the flange member from the front, a rotation restricting member provided on the screw at a portion protruding to the rear side of the flange member, and the rotation restricting member A locking portion screwed into the screw behind the member; and an elastic member and a water-expandable member provided on the flange member, wherein the flange member is substantially perpendicular to the outer peripheral surface of the pipe portion. A second flange portion standing outwardly, a base portion of the second flange portion bent forward, formed along the pipe portion, and joined to the outer peripheral surface of the pipe portion; spaced apart from the second flange portion Provided, in the vicinity of the front end of the said connecting portion, in which a first flange portion you standing substantially parallel outwardly from the second flange portion is formed integrally, the outer diameter of the first flange portion, The elastic member is provided on a rear surface of the first flange portion, and the water-expandable member is formed between the first flange portion and the second flange portion. be between, Oite the outer periphery of the connecting portion, the first flange portion, the second flange portion, and wall portions penetrating member, characterized in that provided in the space formed by the connecting portion .

It is desirable that the axial direction of the pipe portion is shifted with respect to the axial direction of the flange member and is joined by welding, and the pipe portion is joined obliquely to the flange member.

  When the pipe portion is disposed so as to be inclined downward toward the front, a mark portion where the vertical direction of the wall portion penetrating member can be visually recognized may be provided on the front surface of the flange member.

  According to 1st invention, the wall part penetration member which can be easily fixed to a wall part can be obtained.

  Specifically, when the screw is rotated from the front of the flange member, the locking portion moves in the axial direction of the screw until the locking portion contacts the O-ring as the screw rotates. On the other hand, when the engaging portion comes into contact with the O-ring, the engaging portion rotates together with the screw until a part of the engaging portion comes into contact with the outer peripheral surface of the pipe portion. When the locking portion is further rotated and a part of the locking portion comes into contact with the outer peripheral surface of the pipe portion, the locking portion moves in the axial direction of the screw together with the O-ring as the screw rotates.

  Therefore, when attaching the wall part penetrating member to the wall part, by tightening a screw from the front surface of the flange member of the wall part penetrating member, the locking part and the first flange part arranged on the back side of the first flange part Insert the wall. That is, since the wall portion penetrating member is fixed to the wall portion by tightening the screw only from one surface of the wall portion penetrating member, attachment is easy.

  The screw passes through a pair of flange portions that are separated from each other. Therefore, it is possible to prevent the screw shaft from moving. Moreover, since the elastic member is provided on the rear surface of the first flange portion, when the wall portion penetrating member is installed on the wall portion, the gap between the first flange portion and the wall surface is stopped by the elastic member. Moreover, even if moisture permeates between the first flange portion and the wall surface, the water-expandable member is provided on the outer periphery of the connecting portion between the first flange portion and the second flange portion. Therefore, it is possible to reliably prevent moisture from entering the rear side of the second flange portion.

Incidentally, the pipe member and the flange member is formed of metal, the first flange portion of the flange member, the second flange portion and because been formed connecting part integrally, it is easy to manufacture. Moreover, even if it is a case where the fluid which flows through the pipe body penetrated by the wall part penetration member is high temperature compared with the thing made from resin, it is applicable. Therefore, the present invention can be applied to, for example, exhaust of a range hood and intake / exhaust of bathroom heating.

  Further, since the axial directions of the flange portion and the pipe portion are slightly shifted from each other, the pipe portion can be inclined slightly downward when the flange portion is arranged straight on the wall surface. Therefore, it is possible to prevent moisture from flowing from the pipe portion to the inside of the wall surface.

  At this time, by providing a mark on the flange portion so that the orientation of the pipe portion can be understood, the orientation of the pipe portion can be easily visually confirmed. Therefore, it can install reliably so that a pipe part may incline below toward the wall surface exterior.

2nd invention uses the wall part penetration member concerning 1st invention, the said wall part penetration member is installed in the through-hole formed in the wall part, and the outer diameter of the said 1st flange part is the said through-hole. The outer diameter of the second flange portion is formed smaller than the inner diameter of the through hole, and the elastic member on the rear surface of the flange member is formed by the first flange portion and the wall portion. Between the front surface of the wall portion and pressed against the front surface of the wall portion, the water-expandable member is disposed between the outer peripheral portion of the connecting portion and the inner surface of the through hole, and the locking portion is The wall penetrating structure is characterized in that the wall penetrating member is fixed to the wall portion by projecting to the outer peripheral side of the through hole and sandwiching the wall portion by the flange member and the locking portion.

According to the second invention, the outer diameter of the first flange portion is larger than the outer diameter of the through hole, and the outer diameter of the second flange portion is smaller than the inner diameter of the through hole. A wall part penetrating member can be inserted into the hole. At this time, by rotating the screw from one surface of the wall portion, the wall portion is sandwiched between the first flange portion and the engaging portion protruding to the outer peripheral side, so that the wall portion penetrating member is easily fixed to the wall portion. Then, the pipe can be inserted into the wall. Moreover, since it is a simple structure, the installation freedom with respect to a wall part is high. Further, since the elastic member is installed between the first flange portion and the front surface of the wall portion, and the water-expandable member is installed between the outer peripheral portion of the connecting portion and the inner surface of the through hole, the through hole and the wall portion Intrusion of water from the gap with the penetrating member can be prevented.

  Hereinafter, the wall part penetration member concerning the present invention is explained. 1 (a) is a front perspective view showing the wall penetrating member 1, FIG. 1 (b) is a rear perspective view showing the wall penetrating member 1, and FIG. 2 (a) is a front view showing the wall penetrating member 1. 2 (b) is a rear view showing the wall penetrating member 1, FIG. 3 (a) is a right side view showing the wall penetrating member 1, and FIG. 3 (b) is a plan view showing the wall penetrating member 1. FIG. 3 (c) is a bottom view showing the wall penetrating member 1, and FIG. 3 (d) is a left side view showing the wall penetrating member 1. FIG.

  The wall portion penetrating member 1 mainly includes a flange member 3, a pipe portion 5, an elastic member 7, a screw 9, a locking portion 13, a water-expandable member 15, and the like. For the flange member 3 and the pipe portion 5, for example, a metal having good corrosion resistance such as stainless steel or aluminum can be applied.

  The pipe part 5 is a cylindrical body and is formed with a predetermined length. The flange member 3 is joined to the outer peripheral surface of the pipe part 5 by welding or the like. The flange member 3 is integrally formed by a press or the like, for example, and includes a first flange portion 3a, a second flange portion 3b, and the like. Details of the flange member 3 will be described later.

  FIG. 4 is a cross-sectional view in the axial direction showing the wall portion penetrating member 1, and is a cross-sectional view taken along the line AA in FIG. The axial direction (B in the figure) of the flange member 3 and the axial direction (C in the figure) of the pipe portion 5 are shifted. That is, the pipe portion 5 is joined to the flange member 3 with a slight inclination. The inclination angle may be an angle that is displaced about 1 mm in a direction perpendicular to the axial length of 50 mm.

  The wall penetrating member 1 is used so as to incline downward as it goes forward (on the left side in the drawing and on the first flange portion 3a side). That is, the pipe portion 5 projects forward from the upper side of the wall penetrating member 1 relative to the lower side.

  FIG. 5 is an enlarged cross-sectional view of the vicinity of the flange member 3, and is an enlarged view of a portion H in FIG. The second flange portion 3b stands outwardly substantially perpendicular to the axial direction (left and right direction in the drawing) of the pipe portion 5. The base portion of the second flange portion 3 b (near the contact portion with the pipe portion 5) is bent forward, and a connecting portion 3 c is formed along the pipe portion 5 with a predetermined length.

  In the vicinity of the front end of the connecting portion 3c, the first flange portion 3a stands up substantially parallel to the second flange portion 3b. In addition, the outer diameter of the 1st flange part 3a is larger than the 2nd flange part 3b. Further, the vicinity of the front end portion of the first flange portion 3a is bent toward the front (left side in the figure) of 1 of the wall portion penetrating member.

  An elastic member 7 is provided on the rear surface of the first flange portion 3a and in the vicinity of the outer peripheral portion. The elastic member 7 is, for example, a foam or the like, and is easily deformed to fill a gap with the wall surface. The first flange portion 3a and the second flange portion 3b are provided apart from each other by the length of the connecting portion 3c. A water-expandable member 15 is provided on the outer peripheral portion of the connecting portion 3c (between the first flange portion 3a and the second flange portion 3b).

  In addition, the caulking process etc. which abbreviate | omitted illustration is performed between the flange member 3 and the outer peripheral surface of the pipe part 5, and water is stopped. Therefore, water does not enter from the gap between the flange member 3 and the pipe portion 5.

  A screw 9 is provided so as to penetrate through the flange member 3 (the first flange portion 3a and the second flange portion 3b). The screw 9 is inserted from the front side of the first flange portion 3a and penetrates through the second flange portion 3b. In the example shown in FIG. 2, a pair of screws 9 are formed above and below the flange member 3, but may be three or more.

  An O-ring 11 that is a rotation restricting member is provided on the screw 9 at a portion protruding rearward from the second flange portion 3b. The rotation restricting member is a member that prevents the locking part from rotating around the bolt. In the present invention, the rotation restricting member refers to a ring-shaped elastic member. The locking portion 13 is screwed onto the screw 9 further on the rear side than the O-ring 11. As shown in FIG. 2B, the locking portion 13 is folded so as to come into contact with the pipe portion 5 without projecting from the projection surface of the first flange portion 3 a in a normal view in a normal state.

  6A and 6B are diagrams showing a state in which the locking portion 13 is opened outward, FIG. 6A is a rear perspective view, and FIG. 6B is a rear view. The locking portion 13 can rotate until the vicinity of one end of the locking portion 13 (the end on the short side from the screwed portion with the screw 9) contacts the outer peripheral surface of the pipe portion 5. When the locking portion 13 rotates completely, the other end of the locking portion 13 (the end on the longer side from the screwed portion with the screw 9) spreads outward, and in front view, from the first flange portion 3a. Also protrude outwards. In addition, about the rotation method of the latching | locking part 13, a detail is mentioned later.

  Next, the fixing method of the wall part penetration member 1 to the wall part 17 is demonstrated. First, as shown in FIG. 7, in the state in which the locking portion 13 is folded (the locking portion 13 does not protrude outward from the first flange portion 3a), the hole 19 formed in the wall portion 17 The wall penetrating member 1 is inserted (in the direction of arrow D in the figure). The hole 19 is larger than the circumscribed circle of the locking portion 13 in the folded state and the second flange portion 3b, and is smaller than the first flange portion 3a.

  As described above, the wall portion penetrating member 1 has a vertical direction. That is, the wall portion penetrating member 1 is inserted into the hole 19 so that the pipe portion 5 faces downward toward the front. At this time, it is desirable to provide a mark indicating the vertical direction on the front surface of the flange member 3 (first flange portion 3a) so that the orientation of the wall portion penetrating member 1 can be easily recognized. By doing in this way, it can prevent that the installation direction of the wall part penetration member 1 is mistaken.

  Next, as shown to Fig.8 (a), the screw 9 is rotated from the front side (1st flange part 3a side) of the wall part 17 (arrow E direction of a figure). When the screw 9 is rotated, the locking portion 13 moves to the wall 17 side as the screw 9 rotates (in the direction of arrow F in the figure). At this time, since the friction at the screwed portion between the locking portion 13 and the screw 9 is smaller than the own weight of the locking portion 13, the locking portion 13 does not rotate but moves along the pipe portion 5. Therefore, as shown in FIG.8 (b), the latching | locking part 13 maintains the folded state.

  When the screw 9 is further rotated, the locking portion 13 comes into contact with the O-ring 11 as shown in FIG. When the locking portion 13 contacts the O-ring 11, the locking portion 13 receives resistance by the O-ring 11. That is, the movement in the direction of the wall portion 17 (in the direction of arrow F in the figure) receives resistance by the O-ring 11 and the rotation of the locking portion 13 with respect to the screw 9 is restricted. Therefore, as shown in FIG. 9B, the locking portion 13 rotates together with the screw 9 (in the direction of arrow G in the figure). At this time, as described above, the locking portion 13 rotates until one end of the locking portion 13 contacts the outer peripheral surface of the pipe portion 5.

  When the screw 9 is further rotated, the locking portion 13 cannot be rotated any further, so that the locking portion 13 moves in the direction of the wall portion 17 together with the O-ring 11 as shown in FIG. (Arrow F direction in the figure). When the locking portion 13 comes into contact with the back surface of the wall portion 17, the wall portion 17 is sandwiched between the locking portion 13 and the first flange portion 3a. At this time, the wall portion 17 is securely sandwiched between the locking portion 13 and the first flange portion 3a by rotating the screw 9 until the elastic member 7 is completely crushed.

  By performing the above operation on the upper and lower screws 9, the first flange portion 3a is fixed straight to the wall portion 17 as shown in FIG. Then, construction is completed by inserting piping etc. in the wall part penetration member 1. FIG.

  Thus, according to the present invention, when attaching the wall penetrating member 1 to the wall portion 17, the wall penetrating member 1 is fixed to the wall portion 17 by tightening the screw 9 from the front side of the wall portion 17. The For this reason, it is not necessary to work on the front surface and the rear surface of the wall portion 17, and attachment is easy.

  Further, the first flange portion 3 a is reliably pressed against the front surface of the wall portion 17. At this time, the elastic member 7 is provided on the rear surface of the first flange portion 3a, and the elastic member 7 is crushed to absorb the irregularities on the front surface of the wall portion 17, and the front surface of the wall portion 17 and the first flange portion. Intrusion of water from the gap with 3a can be prevented.

  In addition, even if water penetrates behind the first flange portion 3a beyond the elastic member 7, the water expandable member 15 is provided between the first flange portion 3a and the second flange portion 3b. . Therefore, when the water-expandable member 15 expands, it is possible to reliably prevent further intrusion of water.

  Moreover, the pipe part 5 inclines below as it goes ahead slightly (outward of the wall part 17). Therefore, the water that has entered the pipe portion 5 can be prevented from flowing out to the front side of the wall portion 17 and flowing into the rear side of the wall portion 17.

  Moreover, the installation direction of the wall part penetration member 1 is not mistaken by forming the mark which shows direction (up-down direction) of the wall part penetration member 1 in the front surface of the 1st flange part 3a.

  Further, by providing the O-ring 11, the locking portion 13 can be reliably rotated outward. In addition, when removing the wall part penetration member 1, if the screw 9 is rotated reversely, the latching | locking part 13 will rotate in the folded state, and will move back. After the wall portion penetrating member 1 is taken out from the wall portion 17, it can be used again by returning the position of the O-ring 11 to the original position.

  Moreover, since the pipe part 5 and the flange member 3 are metal, it can be used also in the site | part through which a high temperature fluid flows. Moreover, the pipe part 5 is a tubular body, and the flange member 3 can also be easily manufactured by pressing. Moreover, since it can join by welding, joining is also easy. As described above, since the caulking is applied to the contact portion between the pipe portion 5 and the flange member 3, it is possible to prevent water from entering.

  Moreover, since the 1st flange part 3a and the 2nd flange part 3b are spaced apart, when rotating the screw 9, the axial shift of the screw 9 can be prevented. Further, by bending the tip of the first flange portion 3a, the first flange portion 3a has a reinforcing effect. At this time, the front end is bent forward so that it does not interfere with the wall portion 17.

  Although the embodiments of the present invention have been described with reference to the accompanying drawings, the technical scope of the present invention is not affected by the above-described embodiments. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims. It is understood that it belongs.
