Description

  The present invention relates to a drainer and a building.

  In a building such as a house, in order to prevent rainwater or the like flowing down along the outer wall from entering the inside of the building through the gap between the outer wall and the foundation, a technique of providing a water drain at the lower end portion of the outer wall is known. According to this, the rainwater etc. which flowed down along the outer wall can be made to flow from the lower end of the water drainage tool without entering the inside of the building.

  Here, in general, the drainer is attached to the outer wall using screws. In this case, there is a problem that the space between the lower end portion of the outer wall and the foundation is narrow, and the attaching operation is difficult. In addition, if the screw that attaches the drainage tool to the outer wall is exposed outdoors, the screw will rust due to rainwater, etc., or the installation interval of the screws may be uneven (disturbance in the screw pitch), and the aesthetics of the building may be impaired. There was a problem.

  As a countermeasure for the above problem, for example, in a conventional construction method, a mounting structure has been proposed in which a water drainage tool is fixed to a base of an outer wall and an exterior material is attached so as to cover the screw on the outdoor side (for example, Patent Documents) 1). According to this, since the screw is covered with the exterior material, it is not directly visible from the outdoor side. However, in the case of a house by such a conventional construction method, it is possible to adopt the mounting structure described above, but it is impossible in the case of an industrialized house. That is, in the case of an industrialized house, an outer wall panel in which an outer wall base is assembled in advance on the back side of the exterior material is used. In this case, there is no gap between the exterior material and the outer wall base, and the drainer cannot be screwed to the outer wall base.

  Moreover, the attachment structure which can attach a water drainage tool to an outer wall panel without using a screw is proposed. For example, the draining tool of Patent Document 2 includes a draining body extending to the outdoor side and a draining presser formed by a spring plate having spring properties. Then, the draining body is brought into contact with the outdoor side surface of the outer wall base projecting downward from the exterior material, and the draining presser is arranged between the top end of the foundation and the outer wall panel, so that the draining body Is pressed against the outdoor side surface of the outer wall base. Thereby, it is supposed that the screwing work can be eliminated and the ease of construction can be improved.

However, in the draining tool of the above-mentioned Patent Document 2, it is difficult to mount the draining presser between the outer wall panel and the top of the foundation. Moreover, when the attachment work is inadequate, there exists a concern that the attachment state of a drainer main body will become unstable.
JP 2001-152655 A Japanese Patent Laid-Open No. 9-13515

  The present invention has been made in view of the above circumstances, and has as its main object to provide a water drainage tool that does not impair the aesthetics of the building and is excellent in workability, and a building equipped with the water drainage tool. It is.

  The present invention employs the following means in order to solve the above problems.

  The present invention is a drainer provided at a lower end portion of an outer wall panel in which an exterior material and an outer wall base material are pre-assembled, and is attached to the outer wall base material in a state of hanging downward from the lower end portion of the outer wall panel. It has a draining plate portion extending in the vertical direction, and a draining main body attached to the bracket so as to hide the bracket on the back side of the draining plate portion. .

  In general, the portion where the drainage tool is attached at the lower end of the outer wall panel (the portion where the bracket is provided in the present invention) is narrow. In particular, an outer wall panel used in an industrialized house or the like has an exterior material and an outer wall base material assembled in advance, and many restrictions arise when a drainer is attached to the outer wall base material. Therefore, it is difficult to attach the water drainage tool. On the other hand, in this invention, since an attachment site | part is expanded by a bracket, the attachment operation | work becomes easy. Moreover, since the bracket is concealed on the back side of the draining plate portion of the draining body, the bracket is not directly visible from the outside, and the aesthetic appearance of the building is not impaired.

  In addition, it is desirable that the draining main body has a long shape, while the bracket has a short shape with a length having an attachment allowance for at least the outer wall base material. That is, as described above, the attachment part of the water drainage at the lower end portion of the outer wall panel is narrow, but the bracket that is attached to the outer wall panel is short and easy to handle, so the bracket can be easily attached to the outer wall panel. Become. Moreover, since the attachment site | part is expanded by the bracket, even if it is long about the draining body, the attachment operation | work becomes easy.

  The bracket is preferably fixed to the outer wall base material with screws. In this case, the bracket can be firmly fixed to the outer wall base material with screws. As described above, since the bracket is concealed by the draining plate portion, rainwater or the like is not directly applied to the screw. As a result, inconvenience such as rusting of the screw is suppressed, and the quality of the water draining tool can be suitably maintained. Furthermore, even if the screw pitch is disturbed, the aesthetic appearance of the building is not impaired.

  The draining body is provided with an upright portion extending on the back side of the draining plate portion, and the bracket is a hanging plate portion that faces the draining plate portion and hangs down from the outer wall panel in an attached state to the outer wall panel. It is preferable that the hanging plate portion is provided with a coupling receiving portion that can be coupled to the standing portion of the draining plate portion.

  According to the said structure, a drainage main body and a bracket are couple | bonded by the standing part provided in the back side of the drainage board part of the drainage main body, and the coupling | bond receiving part provided in the drooping board part of the bracket. In this case, the draining plate portion of the draining body has a vertical dimension sufficient for draining, so that a sufficient coupling space can be secured behind the draining plate.

  The standing part of the draining body and the coupling receiving part of the bracket may each be provided with an engaging part that is coupled by elastic deformation of at least one of them. In this case, the draining body can be easily attached by pressing the bracket.

  Each engaging portion provided in the standing portion of the draining body and the coupling receiving portion of the bracket is inclined to assist in entering and releasing the engagement state when the draining body is attached to and detached from the bracket. A surface may be formed. In this structure, each engaging part provided in the draining main body and the bracket is engaged or disengaged while being guided by the inclined surface. In such a case, when the draining body is attached to the bracket, the mounting becomes easy, and when the draining body is detached from the bracket, the removal becomes easy. Therefore, when the drainer body is dirty or damaged, the replacement work can be easily performed.

  The draining body is provided with the upright portions spaced apart at two upper and lower positions on the back side of the draining plate portion, and the bracket is provided with the coupling receiving portion according to the position of the upright portion. Good. In this case, in the state in which the draining body is attached to the bracket, the draining body is supported by the two up and down standing parts, so that the draining body can be held in a stable state.

  The standing part of the draining body may be formed of a continuous body extending in the same cross-sectional shape in the longitudinal direction of the draining body. By forming the draining body as a continuous body as described above, it is possible to attach to the bracket at any part of the draining body. In addition, once attached to the bracket, sliding movement in the longitudinal direction is possible. Therefore, it is possible to easily adjust the position of the draining body.

  The draining plate portion of the draining body may be provided with a lower plate portion that covers the bracket from below. In this case, the gap between the outer wall panel and the foundation is narrowed by the lower plate portion in a state where the water drainage is attached to the building. In such a configuration, it becomes difficult to directly attach the draining body to the outer wall panel due to the presence of the lower plate part, but by adopting the configuration in which the bracket is attached in advance as described above, the mounting operation of the draining body may be hindered. Nor.

  The draining body may be provided with a turn-up portion having a large number of small holes of a size that prevents entry of small animals such as sharks. Thereby, in addition to the draining function, the small animal intrusion prevention function for preventing the invasion of small animals such as a spider or the like under the floor can be added to the drainer.

  In a building to which the drainage tool having the above-described characteristic structure is attached, a plurality of the brackets are attached to the lower end portion of the outer wall panel so as to be spaced apart from each other, and spanned over the plurality of brackets. The main body should be attached. Thereby, in a building, the draining body can be held in a stable state.

  In a building, brackets are preferably attached as shown in (1) and (2) below.

  (1) The bracket may be attached to a joining portion between two adjacent outer wall panels. Here, the drainer body is attached to the lower end portion of the outer wall panel so as to straddle the plurality of outer wall panels, but by providing a bracket at the joining portion of the plurality of outer wall panels, the position of each outer wall panel is shifted. Even if (shift of the bracket mounting site) occurs, the draining body can be held in an appropriate state.

  (2) It is good that the bracket is provided in the joining part of two draining main bodies, and the edge part of two draining main bodies is supported with respect to one bracket. In this case, the end of the draining body is prevented from floating.

[First Embodiment]
The first embodiment will be described below with reference to the drawings. In the first embodiment, the building is a building constructed by a steel frame construction method, and a drainer is attached to the outer wall panel of the building. 1 is a perspective view showing an outline of a drainer in the first embodiment, FIG. 2 is a longitudinal sectional view showing a state in which the drainer is attached to a building, and FIG. 3A is a bracket, a drainer body, The longitudinal cross-sectional view which shows the state which has left | separated, (b) is a longitudinal cross-sectional view which shows the state in which the bracket and the draining body are couple | bonded.

  As shown in FIG. 2, a rectangular plate-like column base plate 14 for fixing the column 13 is provided at the top end of the foundation 12 of the building 10. A plurality of column base plates 14 are provided for each column 13, and an angle 15 having an L-shaped cross section is fixed by a bolt 16 so as to be bridged between the plurality of column base plates 14. The angle 15 is provided on the column base plate 14 so that the upright side is located on the outdoor side.

  On the upright side of the angle 15, an outer wall panel 21 is fixed by a bolt 17. Thereby, the outer wall panel 21 is attached to the building 10. The outer wall panel 21 is composed of an exterior material 22 and a base frame 23 attached to the back side thereof. The base frame 23 is composed of a plurality of channel steels, and a part of the lower frame member 23 a is attached so as to protrude below the lower edge of the exterior member 22. In the present embodiment, the height dimension (vertical dimension in the drawing) of the protruding portion of the lower frame member 23a is set to 10 mm. Here, the outer wall panel 21 is provided on the outdoor side of the side surface portion (outdoor side surface) of the foundation 12.

  And the draining tool 11 is attached to the protrusion part of the lower frame material 23a. The draining tool 11 has a structure including a bracket 31 and a draining body 41 each made of an extruded product made of aluminum. In the building 10, the draining tool 11 is integrated with the bracket 31 and the draining body 41. The tool 11 is attached to the outer wall panel 21.

  Hereinafter, the details of the drainer 11 will be described with reference to FIG. In the following description, the vertical direction is described with reference to the direction shown in FIG. 3, that is, the direction attached to the outer wall panel 21.

  The bracket 31 is fixed to the lower frame member 23a of the outer wall panel 21 and detachably supports the draining body 41. The bracket 31 has a mounting base portion 32 having a substantially L-shaped cross section. A vertical portion of the mounting base portion 32 is a vertical side portion 32a, and a horizontal portion is a horizontal side portion 32b. When the bracket 31 is attached to the lower frame member 23a, the vertical side portion 32a and the horizontal side portion 32b of the attachment base portion 32 are in contact with two sides (web and flange) of the lower frame member 23a, and in this state, the vertical side portion At 32a, fastening with a metal screw 61 (small screw) is performed. The vertical side portion 32a of the attachment base portion 32 is formed with a dimension that allows the attachment base portion 32 to be attached to the protruding portion of the lower frame member 23a without interfering with the exterior member 22 and allows screw fixing. . Further, the width dimension (horizontal dimension shown) of the horizontal side portion 32b is formed longer than the height dimension (vertical dimension shown) of the vertical side portion 32a. For this reason, the bracket 31 can be fastened and fixed to the lower frame member 23a in a stable state.

  On the other hand, the draining body 41 has a draining plate portion 42 that forms a draining surface in the vertical direction. The draining plate portion 42 has a length dimension (vertical dimension in the drawing) that can hide at least a gap formed between the lower end of the outer wall panel 21 (exterior material 22) and the top end of the foundation 12, At the upper end portion of the vertical surface portion 42a, an inclined surface portion 42b that is inclined to the back side (the opposite side to the draining surface) is formed.

  The draining body 41 is formed in a long shape. Further, the bracket 31 is formed shorter than the draining body 41. The bracket 31 is used in a connecting portion or the like of two draining main bodies 41, and is formed with a width dimension that allows the two draining main bodies 41 to be connected together at the connecting portion.

  Further, as a configuration for integrating the bracket 31 and the draining body 41, each of these members is provided with a support structure for supporting each other, and the support structure will be described in detail below.

  In the bracket 31, a support plate portion 34 extending downward is integrally formed on the mounting base portion 32, and a pair of upper and lower support arm portions 35 are formed on the support plate portion 34. In the draining main body 41, the draining plate portion 42 is integrally formed with a pair of upper and lower support arm portions 43 on the back side (that is, the bracket side). In the following description, the support arm portion 35 provided on the bracket 31 is referred to as “bracket side arm portion 35”, and the support arm portion 43 provided on the draining main body 41 is referred to as “main body side arm portion 43”.

  The bracket side arm portion 35 is formed of a continuous body extending in the same cross-sectional shape in the longitudinal direction of the bracket 31. Similarly, the main body side arm portion 43 is formed of a continuous body extending in the same cross-sectional shape in the longitudinal direction of the draining main body 41.

  Moreover, the bracket side arm part 35 and the main body side arm part 43 are provided above and below at substantially the same interval. Engaging portions 36 and 44 are formed at the distal end portions of the support arm portions 35 and 43 so as to engage each other. In this case, in the bracket side arm portion 35, the upper and lower two engaging portions 36 are formed as inclined portions inclined toward opposite sides (both outside). That is, the upper engaging portion 36 is inclined upward, and the lower engaging portion 36 is inclined downward. Each engaging portion 36 is formed with an engaging protrusion 36a having a substantially trapezoidal cross section that protrudes inward.

  In the main body side arm portion 43, the upper and lower two engaging portions 44 are formed as bent portions that are bent toward the opposite sides (both inside). That is, the upper engaging portion 44 is bent downward and the lower engaging portion 44 is bent upward. Each engaging portion 44 is formed to be bent in accordance with the engaging portion 36 of the bracket side arm portion 35, and the engaging protrusion 36a is inserted into the engaging concave portion 44a formed by the bending. The engagement recess 44a is formed in accordance with the shape and size of the engagement protrusion 36a of the bracket side arm portion 35.

  The distal end portion of each engaging portion 44 is a guide portion 44b that is inclined toward opposite sides (both inside). The inclination direction of the guide portion 44b is opposite to the inclination direction of the engaging portion 36 formed on the bracket side arm portion 35, and the bracket side arm portion 35 and the main body side arm portion 43 are coupled by this guide portion 44b. In doing so, the upper and lower two engaging portions 44 of the main body side arm portion 43 are guided between the upper and lower two engaging portions 36 of the bracket side arm portion 35.

  When the bracket 31 and the draining body 41 are integrated, a pair of upper and lower body side arm portions 43 formed on the draining body 41 between the pair of upper and lower bracket side arm portions 35 formed on the bracket 31. The tip of each support arm part 35 and 43 is made to contact, and the draining main body 41 is pressed on the bracket 31 in that state. Accordingly, the engaging portions 36 and 44 of the arm portions 35 and 43 are engaged with each other while being elastically deformed between the bracket side arm portion 35 and the main body side arm portion 43. At this time, the engagement protrusion part 36a of the bracket side arm part 35 enters the engagement concave part 44a of the main body side arm part 43.

  In the state of FIG. 3B in which the bracket 31 and the draining main body 41 are integrated, the engagement portions 44 of the pair of upper and lower body side arm portions 43 are similarly formed by the engagement portions 36 of the pair of upper and lower bracket side arm portions 35. Therefore, the draining body 41 is supported by the bracket 31 in a stable state in the vertical direction. In addition, since the engaging protrusion 36a formed on the engaging portion 36 of the bracket side arm portion 35 enters the engaging recess 44a formed on the engaging portion 44 of the main body side arm portion 43, it is in the front-rear direction (detachment direction). The draining body 41 is supported by the bracket 31 in a stable state.

  Further, the draining body 41 is supported by the bracket 31 in a stable state in the vertical direction and the front-rear direction, but is not supported in the lateral direction (longitudinal direction of the draining body 41). The water draining body 41 can be slid in the lateral direction (longitudinal direction of the water draining body 41) with the bracket 31 attached to the bracket 31.

  Further, each of the engaging portions 36 and 44 of the bracket side arm portion 35 and the main body side arm portion 43 is for assisting in being engaged and disengaged when the draining main body 41 is attached to and detached from the bracket 31. Since the inclined surfaces (F1 and F2 shown in FIG. 3A) are formed, the engaging portions 36 and 44 are engaged or disengaged while being guided by the inclined surfaces. Therefore, when the draining body 41 is attached to the bracket 31, the attachment becomes easy, and when the draining body 41 is detached from the bracket 31, the removal becomes easy.

  In the draining main body 41, a lower surface plate portion 46 extending behind the draining plate portion 42 is integrally formed near the lower end portion of the draining plate portion 42. The lower surface plate portion 46 is set to a length dimension (depth dimension) that allows underfloor ventilation in the gap between the end portion and the foundation 12. A turn-up mounting portion 47 is formed integrally with the lower surface plate portion 46. The turn-up mounting portion 47 has a rising portion 47a that rises perpendicularly to the lower surface plate portion 46, and a fixing portion 47b that extends from the upper end to the back side (bracket side). The fixed portion 47b is provided with a turn plate portion 48 made of a steel plate. As shown in FIG. 1, a plurality of vent holes 48 a having a rectangular cross section are formed in the turnover plate portion 48 at a predetermined interval in the direction in which the outer wall panel 21 extends. Thereby, the moist air under the floor is discharged to the outside through the vent hole 48a, and the underfloor ventilation is suitably performed.

  Next, a procedure for attaching the drainer 11 to the building 10 will be described with reference to FIGS. 1, 2, 4 and 5. 4 is a plan view showing an arrangement example of the bracket 31. FIG. 5 is a perspective view showing a procedure for attaching the draining body 41 to the bracket 31. As shown in FIG. In addition, here, a procedure for attaching the building 10 to a straight portion will be described as an example.

  First, as shown in FIGS. 1 and 2, the mounting base portion 32 of the bracket 31 is brought into contact with the corners on the outside of the protruding portion of the lower frame member 23a, and the screws 61 are used at the left and right portions of the vertical side portion 32a. The bracket 31 is attached to the lower frame member 23a. At this time, the bracket 31 is attached to the protruding portion of the lower frame member 23a, that is, a relatively narrow portion, but is a member that is considerably smaller than the draining main body 41, so that its handling is easy, and the attachment work Annoyance has been eliminated.

Here, a plurality of brackets 31 are attached to the lower frame member 23a. At this time, the brackets 31 are attached to portions corresponding to any of the following (1) to (3). FIG. 4 is a plan view showing the mounting position of the bracket 31 with respect to the outer wall panel 21.
(1) A joining portion of two outer wall panels 21 (31A in FIG. 4).
(2) A joining portion of two draining main bodies 41 (31B in FIG. 4).
(3) A portion where the installation interval of the bracket 31 is equal to or less than the predetermined interval L (31C in FIG. 4).
The predetermined interval L in (3) is, for example, 500 mm.

  Then, after the bracket 31 is attached, as shown in FIG. 5, the plurality of draining main bodies 41 are respectively pressed against the bracket 31 and attached. At this time, the attachment part of the draining body 41 is expanded because the bracket 31 hangs downward from the lower end portion of the outer wall panel 21. Therefore, the drainer main body 11 is easy to attach. Further, since the operation of attaching the draining body 41 to the bracket 31 is only a pressing operation, the attachment can be easily performed even when the long draining body 41 is supported by both hands.

  When attaching the plurality of draining main bodies 41, the draining main body 41 to be attached later is attached with a slight gap with respect to the end of the draining main body 41 previously attached (state of solid line in FIG. 5). And after the attachment, the end part of each draining body 41 is contact | abutted without a gap by sliding the draining body 41 to the horizontal direction (longitudinal direction of the draining body 41). In this state, both end portions and intermediate portions of each draining body 41 are supported by the plurality of brackets 31. Further, the bracket 31 disposed at the connecting portion between the draining main bodies 41 supports the two draining main bodies 41 across the two draining main bodies 41.

  In addition, a joiner (not shown) having a substantially U-shaped cross section that is fitted between the main body side arm portions 43 and connects the joint portions may be attached to the joint portion between the draining main bodies 41.

  The draining tool 11 is attached to the base frame 23 by the above attachment procedure. Further, not only the straight portion of the building 10 described above but also the protruding corner portion, the entering corner portion, and the like are attached by a substantially similar attachment procedure by arranging the bracket 31 at a predetermined position. For example, in the case of a protruding corner, the L-shaped draining main body 41 is attached to the corner of the protruding corner in plan view.

  As described above, according to the draining tool 11 attached to the building 10, the surface of the exterior material 22 and the surface of the draining plate portion 42 are substantially flush with each other as shown in FIG. Therefore, rainwater or the like flowing down from the lower edge of the exterior material 22 flows down the draining plate portion 42 and flows down from the lower end thereof. Thereby, it is possible to prevent moisture such as rainwater from entering the building 10 from between the outer wall panel 21 and the foundation 12.

  Further, the inclined surface portion 42 b formed in the draining plate portion 42 extends to the vicinity of the lower edge of the exterior material 22. Therefore, the screw 61 is hidden by the inclined surface portion 42b and cannot be directly seen from the outdoor side.

  The indoor side end of the turn-up plate 48 extends to the upper end of the foundation 12 without contacting the foundation 12. Further, the gap formed between the top end of the foundation 12 and the turn-up portion 48 is such that small animals such as pupae cannot pass through, and the entry of small animals such as pupae under the floor is suppressed. .

  According to the embodiment described above in detail, the following advantageous effects can be obtained.

  With the draining body 41 attached to the bracket 31, the bracket 31 is hidden by the draining body 41 (specifically, the draining plate portion 42). Thereby, the bracket 31 is not directly visible from the outside, and the beauty of the building 10 is not impaired.

  The bracket 31 was attached to the outer wall panel 21 with screws 61. Thereby, the bracket 31 can be firmly attached to the outer wall panel 21. Moreover, since the bracket 31 is hidden by the draining body 41 as described above, rainwater or the like is not directly applied to the screw 61. As a result, inconvenience such as rusting of the screw 61 is suppressed, and the quality of the water draining tool 11 can be suitably maintained. Further, since the screw pitch disturbance (the screws 61 are attached to the left and right ends of the bracket 31 in this embodiment) is not visible from the outside, the aesthetic appearance of the building 10 is not impaired.

  The bracket side arm portion 35 was formed as a continuous body extending in the same cross-sectional shape in the longitudinal direction of the bracket 31. Similarly, the main body side arm portion 43 was formed as a continuous body extending in the same cross-sectional shape in the longitudinal direction of the draining main body 41. Thereby, attachment of the drainage main body 41 with respect to the bracket 31 and position adjustment can be performed easily. Specifically, as long as the drainage body 41 is positioned at the height at which the bracket 31 is attached, the drainage body 41 can be attached anywhere on the bracket 31. The position can be adjusted by sliding in the longitudinal direction of the draining body 41.

  Inclined surfaces (F1 and F2 shown in FIG. 3A) are formed on the engaging portions 36 and 44 of the bracket side arm portion 35 and the main body side arm portion 43, respectively. As a result, the draining body 41 can be detached from the bracket 31, and when the draining body 41 is dirty or damaged, the replacement work can be easily performed.

  The water drain plate portion 42 of the water drain main body 41 is provided with a lower surface plate portion 46 that covers the bracket 31 from below, and the lower surface plate portion 46 is provided with an inverted plate portion 48 having a plurality of vent holes 48a. Thereby, the invasion of small animals such as rabbits can be prevented without impairing the effect of underfloor ventilation. In addition, since the bracket 31 is configured to be attached to the outer wall panel 21, there is no problem in mounting the draining body 41.

  A plurality of short brackets 31 are attached to the lower end portion of the outer wall panel 21 so as to be spaced apart from each other, and the draining body 41 is attached so as to span the plurality of brackets 31. Thereby, the draining body 41 can be held in a stable state.

  Moreover, since the attachment location of the bracket 31 is a joining portion of two adjacent outer wall panels 21, there is a positional shift between the outer wall panels 21 at the time of attachment of the water cutter 31, Even if a displacement occurs between the outer wall panels 21 due to an earthquake or secular change after the attachment, the draining body 41 can be held in an appropriate state. Furthermore, by attaching to the connecting portion of the two draining main bodies 41, the end of the draining main body 41 is prevented from floating.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In FIG. 6, the structure of the drainer 71 in this embodiment is shown. Hereinafter, the same configurations as those of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. The description will focus on differences from the first embodiment.

  As shown in FIG. 6, the drainer 71 roughly includes a bracket 81 and a drainer main body 91. The bracket 81 is attached to the lower frame member 23a with screws 61 at the lateral side portion 82b in the state where the mounting base portion 82 is in contact with the outdoor side corner portion of the lower frame member 23a. A pair of support arm portions 84 that are spaced apart in the depth direction (the lateral direction in the drawing) and extend downward are integrally formed on the lateral side portion 82b. Similarly, a pair of support arm portions 93 that are spaced apart in the depth direction (lateral direction in the drawing) and extend upward are integrally formed on the lower surface portion 92 formed in the draining body 91.

  The indoor support arm 93 formed in the draining body 91 is integrally formed with a turn-up mounting portion 94 extending toward the foundation 12, and the turn-up mounting portion 94 is provided with a turn-up plate portion 95. Yes.
