Description

  The present invention relates to a wall penetration sleeve device, a spacer, a wall penetration sleeve installation method, and an installation structure thereof.

  Conventionally, various wall penetration sleeves installed in a through hole of a wall material for ventilation use or wiring / pipe use have been used. In these applications, the wall penetration sleeve is installed in the through hole of the wall material in an inclined posture in which the wall penetration sleeve is lowered from the indoor side to the outdoor side of the wall material in order to prevent rainwater or the like from flowing into the indoors. Generally, a wall penetration sleeve consists of a cylindrical part which penetrates a wall penetration hole, and a flange part for fixing to a wall. And the installation structure of a wall penetration sleeve is built by making a flange part contact | abut on the outer surface of an inner wall, or the front surface of the waterproof sheet erected perpendicularly between the inner wall and the outer wall, and fixing with waterproof tape etc. .

  For example, patent document 1 is disclosing the hole cover for piping arrange | positioned in the hole (2) of a wall (1) in the inclination attitude | position. The hole cover for piping is fitted to the pipe body (3), the flange (4) integrally formed at one end of the pipe body (3), and the outer peripheral surface of the pipe body (3). An annular washer (6, 10). Since the surfaces of the two washers (6, 10) contacting the wall surface are inclined with respect to the other surface, the pipe body (3) can be attached obliquely downward toward the outside. That is, in the installation structure of Patent Document 1, the washer (6, 10) disposed between the flange portion (4) and the wall (1) has a tapered shape in the cross section, so that the pipe body (3 ) With respect to the horizontal axis.

Japanese Utility Model Publication No. 51-38218

  The hole cover for piping (hereinafter referred to as a wall penetration sleeve device) of Patent Document 1 is configured such that an annular washer (hereinafter referred to as a spacer) having an inclined cross section is disposed between a flange portion and a wall surface to thereby horizontally arrange a pipe body. It can be inclined with respect to the axis. However, the spacer extends so as to contact the upper end and the lower end of the flange portion in the inclined direction, and is configured to be larger than the flange portion so that the entire surface of the flange portion contacts the spacer surface. In order to maintain the practical strength, the spacer must have a certain thickness or more even at the thinnest portion (lower edge in the inclined direction). In other words, even at the thinnest part, the physical thickness does not become zero. That is, in the wall penetration sleeve device of Patent Document 1, it is necessary to inevitably dispose the flange portion in the installation space outside the wall surface by at least the physical thickness of the lower edge of the spacer. Therefore, for example, when the installation space is limited such that the space between the wall surface (front surface of the waterproof sheet) and the outer wall is narrow, the installation work becomes difficult due to the overhang width, or the inclined arrangement of the wall penetration sleeve itself is There was a risk that it would be impossible.

The first contact surface of the spacer is formed shorter than the flange portion in the inclined direction, and the spacer partially closes the gap between the flange portion and the wall surface or the waterproof sheet, and the gap is minimized. A spacer is not interposed between the flange portion and the wall surface or the waterproof sheet at the position.

  According to the wall penetration sleeve device of one embodiment of the present invention, the flange part is formed along the wall surface or the waterproof sheet through the spacer in which the first contact surface and the second contact surface are inclined at a predetermined angle with respect to each other. By disposing, the one end (separation end) of the flange portion is separated from the wall surface or the waterproof sheet, and the other end (proximity end) of the flange portion is brought close to each other, so that the wall penetration sleeve is inclined with respect to the horizontal axis. Can be arranged. In the wall-penetrating sleeve device of the present invention, the first contact surface of the spacer is formed shorter than the flange portion in the inclined direction, and the spacer partially opens the gap between the flange portion and the wall surface or the waterproof sheet. In addition to being closed, no spacer is interposed between the flange portion and the wall surface or the waterproof sheet at a position where the distance between the flange portion and the wall surface or the waterproof sheet is the minimum (near end of the flange portion). That is, in the wall penetration sleeve device of the present invention, the distance between the flange portion and the wall surface or the waterproof sheet can be limited by the physical thickness of the spacer by intentionally forming a space where no spacer is interposed at the proximal end of the flange portion. The flange portion can be disposed closer to the wall surface or the waterproof sheet. Therefore, according to the wall penetration sleeve device of the present invention, it is possible to effectively use the installation space while suppressing the flange portion from protruding into the installation space.

  According to the wall penetration sleeve device of the further embodiment of the present invention, in addition to the above effect, the flange portion and the wall surface or the waterproof sheet are formed by the upper end of the flange portion contacting the upper edge of the first contact surface of the spacer. The maximum gap can be closed with a spacer. Furthermore, when the lower end of the flange portion comes into contact with the wall surface or the waterproof sheet, the minimum gap at the proximal end of the flange portion becomes substantially zero. Thereby, in the state which inclined the flange part with the desired angle with respect to the horizontal axis, the distance between a flange part and a wall surface or a waterproof sheet can be minimized. Therefore, according to the present invention, it is possible to minimize the overhang of the flange portion into the installation space.

  According to the wall penetration sleeve device of the further embodiment of the present invention, in addition to the above effect, the outer frame portion formed on a part of the outer periphery of the spacer is brought into contact with the outer peripheral surface of the flange, thereby being aligned. Thus, the spacer can be easily combined with the wall penetration sleeve. In addition, since the height of the outer frame portion is configured to be equal to the thickness of the flange portion, a step is generated between the flange portion surface and the outer frame portion top surface on one surface opposite to the wall surface or the waterproof sheet. A substantially perfect flat surface can be formed. Therefore, for example, when the waterproof tape is attached and the outer periphery of the flange portion is fixed to the wall surface or the waterproof sheet, the waterproof tape can be firmly attached while suppressing formation of bubbles on the adhesive surface.

  According to the wall penetration sleeve device of the further embodiment of the present invention, in addition to the above effects, the width of the open end of the notch portion is narrower than the outer diameter of the cylindrical portion. Therefore, when the spacer is arranged on the wall penetration sleeve so that the tubular portion is inserted into the notch, the possibility that the spacer unexpectedly falls from the wall penetration sleeve via the open end can be reduced.

  According to the spacer of one embodiment of the present invention, the flange portion is disposed along the wall surface or the waterproof sheet via the spacer in which the first contact surface and the second contact surface are inclined at a predetermined angle with respect to each other. Accordingly, one end (separation end) of the flange portion is separated from the wall surface or the waterproof sheet, and the other end (proximity end) of the flange portion is brought close to the wall surface or the waterproof sheet, so that the wall penetration sleeve can be inclined with respect to the horizontal axis. . The first contact surface of the spacer is formed shorter than the flange portion in the inclined direction, and the spacer partially closes the gap between the flange portion and the wall surface or the waterproof sheet, It is configured not to be interposed between the flange portion and the wall surface or the waterproof sheet at a position where the distance between the flange portion and the wall surface or the waterproof sheet is the minimum (proximal end of the flange portion). That is, the spacer according to the present invention has a possibility that the distance between the flange portion and the wall surface or the waterproof sheet is limited by the physical thickness of the spacer by intentionally forming a space where the spacer is not interposed at the proximal end of the flange portion. This eliminates the flange portion and makes it possible to place the flange portion closer to the wall surface or the waterproof sheet. Therefore, by utilizing the spacer of the present invention, it is possible to effectively utilize the installation space while suppressing the flange portion from protruding into the installation space.

  According to the wall penetration sleeve installation method of one embodiment of the present invention, by selecting a spacer in which the first contact surface and the second contact surface are inclined at a desired angle with respect to each other, When the flange portion is arranged along the wall surface or the waterproof sheet, one end (separated end) of the flange portion is separated from the wall surface or the waterproof sheet, and the other end (proximal end) of the flange portion is brought close to the wall through sleeve. Can be disposed at a desired angle with respect to the horizontal axis. In the installation method of the present invention, the first contact surface of the spacer is formed to be shorter than the flange portion in the inclined direction, and the gap between the flange portion and the wall surface or the waterproof sheet is partially blocked by the spacer. The spacer is not interposed between the flange portion and the wall surface or the waterproof sheet at a position where the distance between the flange portion and the wall surface or the waterproof sheet is the minimum (near end of the flange portion). In other words, the installation method of the present invention has a possibility that the distance between the flange portion and the wall surface or the waterproof sheet is limited by the physical thickness of the spacer by intentionally forming a space where no spacer is interposed at the proximal end of the flange portion. This eliminates the flange portion and makes it possible to place the flange portion closer to the wall surface or the waterproof sheet. Therefore, according to the present invention, it is possible to install the wall penetration sleeve on the wall material in a form in which the installation space is effectively used while preventing the flange portion from protruding into the installation space.

  According to the wall penetrating sleeve installation method of the further embodiment of the present invention, in addition to the above effect, the flange portion and the wall surface or waterproofing is achieved by the upper end of the flange portion contacting the upper edge of the first contact surface of the spacer. The maximum gap of the sheet can be closed with a spacer. Furthermore, by bringing the lower end of the flange portion into contact with the wall surface or the waterproof sheet, the minimum gap at the proximal end of the flange portion can be made substantially zero. Thereby, in the state which inclined the flange part with the desired angle with respect to the horizontal axis, the distance between a flange part and a wall surface or a waterproof sheet can be minimized. And it is possible to prevent water from flowing into the through hole by at least partially closing a minute gap between the outer periphery of the flange portion and the wall surface or the waterproof sheet with a waterproof tape, a caulking material, or the like.

  According to one embodiment of the present invention, according to the wall penetration sleeve installation structure, the flange portion is attached to the wall surface or the waterproof sheet via the spacer in which the first contact surface and the second contact surface are inclined at a predetermined angle with respect to each other. By arranging along the wall, the one end (separated end) of the flange portion is separated from the wall surface or the waterproof sheet, and the other end (proximal end) of the flange portion is brought close to the wall or the waterproof sheet. Tilted. In the installation structure of the present invention, the first contact surface of the spacer is formed to be shorter than the flange portion in the inclination direction, and the spacer partially forms a gap between the flange portion and the wall surface or the waterproof sheet. In addition to being closed, no spacer is interposed between the flange portion and the wall surface or the waterproof sheet at a position where the distance between the flange portion and the wall surface or the waterproof sheet is minimized (proximal end of the flange portion). That is, in the installation structure of the present invention, the distance between the flange portion and the wall surface or the waterproof sheet is not limited by the physical thickness of the spacer because the space where no spacer is interposed is formed at the proximal end of the flange portion. . Thereby, the flange portion is arranged closer to the wall surface or the waterproof sheet.

Example 1
One embodiment of the invention described herein is a through-wall sleeve device 100 for ventilating waterproof state by communication between the outdoor outside the inner indoor and exterior wall W _ex inner wall W. However, the wall penetration sleeve device of the present invention is not limited to the ventilation application of the present embodiment, and may be used for any application in which the wall penetration sleeve is installed in the wall penetration hole.

  FIG. 1 is a perspective view of a wall penetration sleeve device 100 according to an embodiment. As shown in FIG. 1, a wall penetration sleeve device 100 includes a wall penetration sleeve 110 disposed in a wall penetration hole to ventilate indoors and outdoors, and a spacer 120 for inclining the wall penetration sleeve 110 with respect to a horizontal axis Q. And comprising.

  2A and 2B are a front view and a rear view of the wall-penetrating sleeve device 100, and FIGS. 3A and 3B are a side view and a longitudinal sectional view of the wall-penetrating sleeve device 100. FIG. . 2A and 2B, in the wall penetration sleeve device 100 of the present embodiment, the front surface of the flange portion 112 of the wall penetration sleeve 110 and the end surface of the outer frame portion 123 of the spacer 120 are exposed to the front side, and The lower portion of the rear surface of the flange portion 112 and the rear surface of the spacer 120 (second contact surface 122) are exposed on the rear surface side. And the front-end | tip of the grooved connection part 113 of the wall penetration sleeve 110 is opened by the front, and the front-end | tip of the cylindrical part 111 is opened by the back surface. That is, the spacer 120 is disposed over the outer periphery of the cylindrical portion 111 of the wall penetration sleeve 110, and the spacer 120 covers the majority region above the flange portion 112 from the back surface of the wall penetration sleeve 110.

  As shown in FIGS. 3A and 3B, the ventilation through passage defined by the tubular portion 111 and the grooved connecting portion 113 of the wall penetration sleeve 110 so as to penetrate the front and rear of the wall penetration sleeve device 100. Is extended. The spacer 120 is combined with the wall-through sleeve 110 so that the front surface of the spacer 120 (first contact surface 112) comes into contact with the back surface of the flange portion 112 of the wall-through sleeve 110. At this time, the upper end and both side ends of the rear surface of the flange portion 112 and the upper edge and both side ends of the first contact surface 112 of the spacer 120 are matched, and the upper end surface and both end surfaces of the flange portion 112 are outside the spacer 120. It is covered from the outside by the frame part 123. As shown in FIG. 3A, on the front surface of the wall penetration sleeve device 100, the front surface of the flange portion 112 and the end surface of the outer frame portion 123 cooperate to form a flat surface.

  In this wall penetration sleeve device 100, the front surface of the flange portion 112 forming the front surface is orthogonal to the sleeve axis P of the wall penetration sleeve 110, and on the other hand, the back surface of the spacer 120 forming the back surface of the wall penetration sleeve device 100 (second contact). The surface 122) is offset from the orthogonal axis of the sleeve axis P by a predetermined angle. That is, as described later, the second contact surface 122 (having a vertical surface) is formed by inclining the second contact surface 122 of the wall-penetrating sleeve device 100 with respect to the flange portion 112 orthogonal to the sleeve axis P. ) The sleeve shaft P can be inclined with respect to the horizontal axis Q when being brought into surface contact with the wall surface or the waterproof sheet.

  Further, the spacer 120 does not extend to the vicinity of the lower end of the flange portion 112 on the back surface of the wall penetration sleeve device 100. That is, as will be described later, when the wall penetration sleeve device 100 is installed, the spacer 120 can block a part of the gap between the wall surface or the waterproof sheet and the flange portion 112 (that is, the upper majority region of the flange portion 112). There is no spacer 120 in the vicinity of the lower end of the flange portion 112 where there is a minimum gap.

  Next, each component of the wall penetration sleeve apparatus 100 of one Embodiment is demonstrated in detail with reference to FIGS.

  4 is a perspective view of the wall penetration sleeve 110 of the wall penetration sleeve device 100. FIGS. 5A, 5B, and 5C are a front view, a rear view, and a side view of the wall penetration sleeve 110. FIG. . As shown in FIG. 4, the wall penetration sleeve 110 has a substantially cylindrical tubular portion 111 extending to one side with a length capable of penetrating a wall material, and a flange portion 112 extending in a direction orthogonal to the tubular portion 111. And a grooved connecting portion 113 having a plurality of grooves on the outer periphery extending from the flange portion 112 to the other side.

  As shown in FIGS. 5A and 5B, the cylindrical portion 111 and the grooved connecting portion 113 are in communication with each other and open at their tips. The tubular portion 111 and the grooved connecting portion 113 have a substantially circular shape when viewed from the front (or a cross-sectional view), and the outer diameter of the tubular portion 111 is larger than the outer diameter of the grooved connecting portion 113. large. As will be described later, the distal end of the cylindrical portion 111 is configured so that the piping cap 140 can be fitted from the indoor side of the inner wall, and is configured so that the piping cap 140 can be fitted from the outdoor side of the outer wall (see FIG. 9). And the axis | shaft which passes along the center of the cylindrical part 111 and the grooved connection part 113, and extended along these longitudinal directions was defined as the sleeve axis | shaft P (refer FIG.5 (c)).

  The flange portion 112 of the wall penetration sleeve 110 is formed in a substantially square flat thin plate shape, and its four corners are chamfered. And the vertical width which is the length of the inclination direction of the flange part 112 was defined as L2. The flange portion 112 is formed integrally with the cylindrical portion 111 and the grooved connecting portion 113. The plane of the flange portion 112 is orthogonal to the sleeve axis P, and the sleeve axis P passes through the center of the flange portion 112. Further, the flange portion 112 is formed with four spacers 120 and first fixing portions 114 for fixing to a construction material such as a wall or a cross with a wood screw or the like. The fixing portion 114 is formed thin so that it can be punched with a wood screw.

  In addition, the wall penetration sleeve 110 of this embodiment was produced by integrally molding a hard synthetic resin. However, the present invention is not limited to the manufacturing method and material of one embodiment. For example, instead of molding with a synthetic resin, a metal plate can be welded. Or you may assemble as a separate body, without integrally forming the flange part and cylindrical part of a wall penetration sleeve. Moreover, in the wall penetration sleeve 110 of this embodiment, although the cylindrical part 111 is formed in the cross sectional view circular shape and the flange part 112 is formed in the square shape, this invention is not limited to this and is used. These shapes can be designed arbitrarily according to the situation. For example, the cross-sectional shape of the cylindrical part may be formed in a polygon, or the flange part may be formed in a circular shape.

  FIG. 6 is a perspective view of the spacer 120 of the wall penetration sleeve device 100, and FIGS. 7A to 7D are a front view, a rear view, a bottom view, and a side view. The spacer 120 of the present embodiment is formed by an upper edge extending on a straight line, both side edges extending substantially perpendicularly from the upper edge, a lower edge extending parallel to the upper edge, and the lower edge notched upward. It is bordered by an arcuate inner edge. Then, similarly to the flange portion 112, the two corners of the upper side of the spacer 120 are chamfered. That is, the spacer 120 is similar to a shape obtained by cutting the flange portion 112 in the lateral width direction at a position closer to the lower side in front view or rear view.

  As shown in FIGS. 6 and 7, the spacer 120 includes a first contact surface 121 disposed on the front side of the wall penetration sleeve device 100 and a second contact on the back side of the first contact surface 121. A surface 122. The first contact surface 121 is a flat surface and is configured to be able to come into surface contact with the back surface of the flange portion 114 (the surface on the side from which the cylindrical portion 111 protrudes). As shown in FIGS. 2 and 3, the first abutment surface 121 has a width substantially equal to the flange portion 112, but the first abutment surface 121 is larger than the flange portion 112 in the vertical direction (that is, the inclined direction). It is formed short. In addition, an outer frame portion 123 is formed adjacent to the upper edge and both side edges (that is, the outer periphery excluding the lower edge) of the first contact surface 121. On the other hand, the second contact surface 122 is composed of end surfaces (arranged on the same plane) of ribs 125 extending vertically and horizontally on the back surface of the first contact surface 121 and can be in surface contact with the waterproof sheet S (or the wall surface of the wall material). It is configured. The rib 125 extends vertically and horizontally inside the second contact surface 122 and borders the inner and outer peripheral edges. The protruding width of the rib 125 decreases from the upper edge to the lower edge of the spacer 120. That is, the protruding width of the rib 125 changes linearly so that the thickness of the spacer 120 is the thickest at the upper edge and the thinnest at the lower edge (see FIG. 7D). Furthermore, second fixing portions 126 corresponding to the first fixing portions 114 of the wall penetration sleeve 110 are provided at the two corners of the upper edge of the second contact surface 122 so as to be connected to the rib 125. . In addition, since the second contact surface 122 is formed on the end surface of the rib 125 in the spacer 120, the volume of the entire spacer 120 can be reduced. Thereby, there are additional effects such as reduction of material cost and weight reduction of the spacer. However, the second contact surface of the present invention is not limited to this form. For example, the second contact surface may be a flat surface similar to the first contact surface 121 instead of forming the ribs 125 vertically and horizontally.

  As shown in FIGS. 7A and 7B, the spacer 120 is formed with a notch 124 having an open end 124a at the lower edge thereof. The cutout portion 124 is formed as an arc corresponding to the outer diameter of the tubular portion 111 when viewed from the front. Further, the central axis of the arc of the cutout portion 124 is configured to be concentric with the cylindrical portion 111 when the spacer 120 is combined with the wall penetration sleeve 110. And the center angle of the circular arc of the notch part 124 is larger than 180 degree | times. That is, at the lower edge of the spacer 120, an open end 124a having a width narrower than the diameter of the arc (the outer diameter of the cylindrical portion 111) is formed. The cylindrical portion 111 inserted through the cutout portion 124 cannot pass through the open end 124a.

  As shown in FIGS. 7C and 7D, the spacer 120 has a substantially trapezoidal shape formed so that the thickness thereof becomes thinner from the upper end toward the lower end at a constant rate in a side view. That is, the first contact surface 121 is inclined relative to the second contact surface 122. Further, as shown in FIG. 7D, the outer frame portion 123 is erected at a constant height at the upper edge and the side edge of the first contact surface 121. The height of the outer frame portion 123 from the first contact surface 121 (the distance from the first contact surface 121 to the end surface of the outer frame portion 123) is designed to be substantially equal to the thickness of the flange portion 112. .

  FIG. 8 is a longitudinal sectional view passing through the central axis of the spacer 120. With reference to FIG. 8, the geometry of the spacer 120 will be described in more detail. As shown in FIG. 8, the first contact surface 121 of the spacer 120 has a length L1 from the upper edge to the lower edge along the inclined direction. Note that the length L1 is a concept that does not include the thickness of the outer frame portion 123. The length L1 is set to be smaller than the vertical width L2 of the flange portion 112. In the spacer 120, the first contact surface 121 and the second contact surface 122 are relatively inclined at an inclination angle α. This inclination angle α corresponds to the inclination angle between the sleeve axis P of the wall penetration sleeve 110 and the horizontal axis Q, and can be arbitrarily set to obtain a desired inclination angle of the sleeve axis P. On the other hand, the outer peripheral surface of the spacer 120 and the second contact surface 122 are formed at a substantially right angle. The upper edge of the spacer 120 has a maximum thickness t1, and the lower edge has a minimum thickness t2. The length L1 and the thickness t2 can be arbitrarily selected such that the length L1 is smaller than the vertical width L2, but at least the spacer 120 has a practical strength that is not fragile or can be easily molded. It is preferable to set so as to be formed. That is, the thinner the minimum thickness t2, the more fragile the spacer itself becomes, and the more difficult it is to mold the spacer. Therefore, in view of practicality, the thickness t2 is preferably 0.5 mm or more.

Further, as shown in FIG. 8, a virtual line extending downward from the first contact surface 121 and a virtual line extending downward from the second contact surface 122 intersect to form a virtual substantially right triangle. In other words, the spacer 120 has a trapezoidal shape in which a tip portion of a virtual right triangle is cut. The length of the hypotenuse of the virtual right triangle (the distance from the upper edge of the first contact surface 121 to the intersection of the virtual lines) is defined as L1 ′. At this time, the relationship among the thickness t1, the inclination angle α, and the virtual hypotenuse length L1 ′ is
L1 ′ = t1 / sin (α) [Formula 1]
It is represented by That is, the virtual hypotenuse length L1 ′ can be determined by changing the thickness t1 with respect to the selected desired inclination angle α. As will be described later, the minimum distance d between the flange portion 112 and the waterproof sheet S (or wall surface) is determined by the relationship between the virtual hypotenuse length L1 ′ and the vertical width L2 of the flange portion 112.

  In addition, the spacer 120 of this embodiment was produced by integrally molding a hard synthetic resin. However, the present invention is not limited to the manufacturing method and material of one embodiment. For example, instead of molding with synthetic resin, it is also possible to produce with a material such as metal or wood. Further, the shape of the spacer is not limited to the spacer 120 of the embodiment. That is, in the spacer, at least the first contact surface and the second contact surface are inclined with each other at an inclination angle α, and the length L1 of the first contact surface is the vertical width of the flange portion (length in the inclination direction). For example, it can be arbitrarily designed in accordance with the shape of the corresponding flange portion or the like. Further, as the shape of the spacer, the notch portion may be a perfect circle, the center angle of the notch portion may be 180 degrees or less, or the outer frame portion may be omitted.

FIG. 9 is a perspective view of the wall penetration sleeve installation structure 10 using the wall penetration sleeve device 100 of the embodiment. In FIG. 9, the outer wall W _ex and the piping cap 140 are illustrated separately from the inner wall (wall material) W and the wall penetration sleeve device 100 for the sake of clarity. FIG. 10 is a longitudinal sectional view taken along the vertical direction at the center of the wall through hole of the wall through sleeve installation structure 10 of FIG. In FIG. 10, the piping cap 140 is omitted for explanation.

As shown in FIG. 9 and FIG. 10, an inner wall W is erected on the indoor side pillar side, and a waterproof sheet S is stretched on the outdoor side pillar side. The wall surface of the inner wall W and the plane of the waterproof sheet S extend substantially vertically. And two rungs T are installed between the two studs. Further, a trunk edge material (not shown) is formed on the front surface of the waterproof sheet S, and an outer wall W _ex is erected on the front surface of the trunk edge material. Moreover, the waterproof sheet S, the through holes H1, H2, H3 of substantially the same shape on the inner wall W and the outer wall _{W ex} is bored respectively, the through holes H1, H2, H3 are arranged concentrically, communicate with each other ing. That is, the inner wall W, the center of each through-hole H1~3 tarpaulin S and the outer wall W _ex are aligned along the horizontal axis Q. The waterproof sheet S in the wall through the sleeve device 100, to form a through passage for ventilation penetrating the interior wall W and the outer wall W _ex, through-wall sleeve 110 is disposed through the entire through hole H1～3.

Describing in more detail with reference to FIG. 10, the flange portion 112 and the spacer 120 are located in the installation space between the outer wall W _ex and the waterproof sheet S, and the grooved connecting portion 113 is a through hole of the outer wall W _ex . Arranged in H3. On the other hand, the cylindrical portion 111 of the wall penetration sleeve 110 extends rearward, extends through the through hole H1 of the waterproof sheet S and extends into the through hole H2 of the inner wall W. At this time, the two rungs T are positioned so as to sandwich the through sleeve 110 from above and below. The first contact surface 121 of the spacer 120 is in contact with the back surface of the flange portion 112, and the second contact surface 122 is in contact with the front surface of the waterproof sheet S. That is, the flange portion 112 is inclined by the inclination angle α of the spacer 120 because the flange portion 112 has moved to the outer wall _Wex side by the thickness of the spacer 120. As a result, the sleeve axis P passing through the centers of the cylindrical portion 111 and the grooved connecting portion 113 is inclined obliquely downward toward the outer wall _Wex with respect to the horizontal axis Q at an inclination angle α. At this time, the gap between the upper end of the flange portion 112 and the waterproof sheet S is the largest, and the gap between the lower end of the flange portion 112 and the waterproof sheet S is the smallest. That is, the upper end of the flange portion 112 is a separation end, and the lower end of the flange portion 112 is a proximity end.

  Further, in the wall penetration sleeve installation structure 10, the upper end of the flange portion 112 and the upper edge of the spacer 120 coincide with each other, and in the upper majority portion where the spacer 120 is interposed, between the flange portion 112 and the waterproof sheet S. The gap is closed by the spacer 120. Since the length L1 of the first contact surface 121 of the spacer 120 is shorter than the vertical width L2 of the flange portion 112, the spacer 120 is located between the flange portion 112 and the waterproof sheet S near the proximal end of the flange portion 112. Is not present. 10, the lower end of the flange portion 112 is in contact with the waterproof sheet S.

  Furthermore, in this wall penetration sleeve installation structure 10, the flange part 112 and the spacer 120 are being fixed to the crosspiece T (a part of construction material) with the wood screw 132 through the waterproof sheet S. FIG. Moreover, the waterproof tape 130 is stuck from the front so that between the upper end and side end of the flange part 120, and the waterproof sheet S may be sealed in a water-stopped state. At this time, as shown in FIG. 10, the end surface of the outer frame portion 123 of the spacer 120 and the front surface of the flange portion 112 are flush with each other. Therefore, it is possible to suppress the generation of bubbles on the bonding surface of the waterproof tape 130 and firmly bond the flange portion 112 and the spacer 120 to the waterproof sheet S in a water-stopped state.

  FIG. 11 is a schematic diagram showing the positional relationship between the flange portion 112, the spacer 120, and the waterproof sheet S of the wall penetration sleeve installation structure 10 of FIG. That is, in FIG. 11, a configuration unnecessary for description is omitted. With reference to FIG. 11, the relationship between the respective shape dimensions L1, L1 ′, L2, and α of the flange portion 112 and the spacer 120 in the wall penetration sleeve installation structure 10 will be described. In the form of FIG. 11, the lower end of the flange portion 112 is in contact with the front surface of the waterproof sheet S. That is, the distance between the flange portion 112 and the waterproof sheet S at the proximal end of the flange portion 112 where the gap is minimum is zero. As shown in FIG. 11, the rear surface of the flange portion 112 is disposed on the hypotenuse of the virtual triangle of the spacer 120, and the hypothetical hypotenuse length L <b> 1 ′ of the spacer 120 is equal to the vertical width L <b> 2 (> L <b> 1). That is, as shown in FIGS. 10 and 11, in order to minimize the protrusion of the flange 112 from the waterproof sheet S (minimum distance d to 0), L2 = L1 ′ (= t1 / sin (α)) It is preferable to set the thickness t1 and the inclination angle α of the spacer 120 so as to satisfy the relationship.

FIG. 12 is a schematic diagram of the wall penetration sleeve installation structure 10 ′ in which only the thickness t1 is increased without changing the vertical width L2 and the inclination angle α from the configuration of FIG. In this embodiment, the virtual hypotenuse length L1 ′ of the spacer 120 is larger than L2, and the lower end of the flange portion 112 is separated from the front surface of the waterproof sheet S by a distance d. That is, the distance d between the proximal end of the flange portion 112 and the waterproof sheet S is greater than zero. The relationship between the virtual hypotenuse length L1 ′, the vertical width L2, the inclination angle α, and the distance d is
d = (L1′−L2) sin (α) [Formula 2]
It is represented by And combining Equation 1 and Equation 2,
d = (t1 / sin (α) −L2) sin (α) [Formula 3]
It becomes. Therefore, by selecting the thickness t1 and the inclination angle α of the spacer 120 according to the vertical width L2 of the flange portion 112, the overhang width (distance d) of the flange portion 112 can be arbitrarily adjusted. In other words, since the spacer 120 is not interposed at the proximal end of the flange portion 112, the distance d can be set with a high degree of freedom without the distance d being limited by the physical thickness of the spacer 120.

  On the other hand, although not shown, when the thickness t1 is decreased without changing the inclination angle α of the spacer 120 from the form of FIG. 11, the virtual hypotenuse length L1 'with which the flange portion 112 contacts is smaller than the vertical width L2. Therefore, the lower end of the flange portion 112 hits the waterproof sheet S, or a gap is generated between the flange portion 112 and the spacer 120, and both the first contact surface 121 and the second contact surface 122 of the spacer 120 are flanged. It becomes difficult to make surface contact with the back surface of the portion 112 and the waterproof sheet S at the same time. However, if the waterproof sheet S is a flexible material, the flange portion 112, the spacer 120, and the waterproof sheet S can be disposed in close contact by causing the lower end of the flange portion 122 to bite into the soft flat surface of the waterproof sheet S. it can. That is, according to the material of the waterproof sheet S, the shape of the spacer 120 can be designed such that the distance d <0, thereby increasing the degree of adhesion.

  In the wall penetration sleeve device 100 of this embodiment, L1 = 158 mm, L2 = 230 mm, t1 = 8 mm, t2 = 2.5 mm, and α = 2 °. When the hypotenuse length L1 'of the virtual triangle of the spacer 120 is calculated based on Equation 1, L1' = 229.2 mm. That is, in this embodiment, since the spacer 120 is designed so that the hypotenuse length L1 'is substantially equal to the vertical width L2 of the flange portion 112, the distance d is substantially zero. However, the present invention is not limited to the above-described geometric dimensions, and the geometric dimensions can be arbitrarily set. Moreover, in the wall penetration sleeve installation structure 10 of this embodiment, although it arrange | positions so that the cylindrical part 111 may fall from the indoor side to the outdoor side, this invention is not limited to this. That is, according to a situation, you may install so that the cylindrical part 111 may fall from the outdoor side to an indoor side by arrange | positioning the spacer 120 upside down.

  Next, with reference to FIG. 13, a method of installing the wall penetration sleeve 110 to construct the wall penetration sleeve installation structure 10 will be described. First, a spacer 120 having a predetermined inclination angle α is selected according to a desired inclination angle of the sleeve axis P. Next, the spacer 120 is combined with the back surface side of the flange portion 112 of the wall penetration sleeve 110 in order to dispose the spacer 120 between the waterproof sheet S and the flange portion 112. At this time, the first contact surface 121 is brought into surface contact with the back surface of the flange portion 112 in a state where the upper edge of the first contact surface 121 of the spacer 120 is in contact with the upper end of the flange portion 112. In this step, the inner side surface of the outer frame portion 123 of the spacer 120 is disposed so as to engage with the end surfaces of the upper end and the side end of the flange portion 112, whereby both can be easily positioned and fixed. Furthermore, since the open end of the notch 123 of the spacer 120 is narrowed, the spacer 120 is prevented from falling off from the state over the tubular portion 111 of the wall penetration sleeve 110 via the open end 124a. Note that a double-sided tape, an adhesive, or the like may be used to temporarily connect the flange portion 112 and the spacer 120.

  Subsequently, the cylindrical portion 111 of the wall penetration sleeve 110 is inserted into the through hole H1 of the waterproof sheet S and the through hole H2 of the inner wall W, and the second contact surface 122 of the spacer 120 is brought into contact with the vertical surface of the waterproof sheet S. By making contact with each other, the sleeve axis P of the wall penetration sleeve 110 is inclined with respect to the horizontal axis Q at a desired angle α. At this time, the wall penetration sleeve device 100 may be directed to the waterproof sheet S along a ruled line previously written on the waterproof sheet S so that the sleeve shaft P does not tilt to the left and right. Then, the wall penetration sleeve device 100 can be fixed to the waterproof sheet S (the crosspiece T) by passing the wood screw 132 through the first fixing portion 114 of the flange portion 112 and the second fixing portion 126 of the spacer 120. it can. Next, the wall penetration sleeve installation structure 10 is constructed by closing between at least a part of the outer periphery of the flange portion 112 (and the end face of the outer frame portion 123) and the waterproof sheet S with the waterproof tape 130.

As an additional step, an outer wall W _ex is erected on the front surface of the waterproof sheet S, and the piping cap 140 is fitted into the grooved connecting portion 113 through the through hole H3 of the outer wall W _ex , and the through hole H2 of the inner wall W is inserted. The pipe cap 140 is fitted into the tip of the cylindrical portion 111 through the gap (see FIG. 9). As a result, a waterproof ventilation device that communicates indoors and outdoors is installed. Note that the method described here is merely an example, and those skilled in the art can change the order of the steps or omit unnecessary steps.

  Hereinafter, the operational effects of the wall penetration sleeve device 100 (spacer 120, wall penetration sleeve installation method, and wall penetration sleeve installation structure 10) according to an embodiment of the present invention will be described.

  According to the wall penetration sleeve device 100 (spacer 120, wall penetration sleeve installation method, and wall penetration sleeve installation structure 10) of one embodiment, the first contact surface 121 and the second contact surface 122 of the spacer 120 are opposed to each other. It is inclined at a predetermined angle α. Therefore, by fixing the flange portion 112 to the waterproof sheet S (or the inner wall W wall surface) via the spacer 120, the upper end of the flange portion 112 is separated from the waterproof sheet S and the flange portion 112. The sleeve shaft P of the wall penetration sleeve 110 can be inclined with respect to the horizontal axis Q by bringing the lower ends close to each other. In the wall penetration sleeve device 100 according to the present embodiment, the length L1 from the upper edge to the lower edge of the first contact surface 121 of the spacer 120 is shorter than the vertical width L2 of the flange portion 112 in the inclined direction. ing. Then, when the upper end of the flange portion 112 is arranged so as to match the upper edge of the first contact surface 121, the spacer 120 closes the majority of the upper portion of the gap between the flange portion 112 and the waterproof sheet S, and The spacer 120 is not interposed between the flange portion 112 and the waterproof sheet S at a position where the distance d between the flange portion 112 and the waterproof sheet S is minimized. That is, the wall penetration sleeve device 100 of the present embodiment dares to form a space where the spacer 120 is not interposed at the proximal end of the flange portion 112, so that the minimum distance d between the flange portion 112 and the waterproof sheet S is the physical distance of the spacer 120. The possibility of being limited by the target thickness is eliminated, and the flange portion 112 can be disposed closer to the waterproof sheet S. In addition, the distance d can be freely designed by selecting the shape (inclination angle α, thickness t1) of the spacer 120 according to the shape of the flange portion 112 (vertical width L2). Therefore, according to the wall penetration sleeve device 100 of the present embodiment, it is possible to effectively use the installation space while suppressing the flange portion 112 from protruding into the installation space.

  Furthermore, the wall penetration sleeve apparatus 100 of one Embodiment combines the wall penetration sleeve 110 with which the cylindrical part 111 and the flange part 112 orthogonally crossed, and the spacer 120 formed with the predetermined inclination | tilt angle (alpha). Such a through-wall sleeve 110 is generally available. And by using this wall penetration sleeve 110 in combination with the spacer 120 of various shapes, the wall penetration sleeve apparatus 100 of this embodiment exhibits high versatility. For example, even when the desired inclination angle of the sleeve axis P is diverse, it is easy to select a spacer 120 having a desired shape from a plurality of spacer shapes and combine it with one wall penetration sleeve 110. It can correspond to. Moreover, the required wall-through sleeve device 100 can be constructed by retrofitting one or more spacers 120 to one (eg, off-the-shelf) wall-through sleeve 110, and the wall The cost for installing the penetration sleeve can be greatly improved.

(Example 2)
In the wall penetration sleeve installation structure 10 of one embodiment, the wall penetration sleeve device 100 is installed on the front surface of the waterproof sheet S, but the present invention is not limited to this. For example, as in the installation structure 20 of FIG. 14, the wall penetration sleeve device 100 can be directly installed on the wall surface of one wall member (inner wall or outer wall) W ′ in which the through hole H4 is formed. As shown in FIG. 14, the first contact surface 121 of the spacer 120 contacts the rear surface of the flange portion 112 of the wall penetration sleeve 110, and the second contact surface 122 directly contacts the wall surface of the wall material W ′. ing. As a result, in the wall penetration sleeve installation structure 20, the cylindrical portion 111 passes through the through hole H <b> 4 in a posture in which the sleeve axis P of the wall penetration sleeve 110 is inclined by the inclination angle α with respect to the horizontal axis Q. Note that when the wall material W ′ is an outer wall, the adhesive strength of the waterproof tape 130 decreases with time, so a caulking material may be used instead of the waterproof tape 130.

  The present invention is not limited to the above-described embodiments and modifications, and can be implemented in various modes as long as they belong to the technical scope of the present invention.
