  Embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

  First, the premise of the drainage mounting structure according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a cross-sectional view showing a drainage mounting structure according to the present embodiment. FIG. 2 is a perspective view showing a configuration of the drainage fixture 5 according to the present embodiment.

  With reference to FIG. 1 and FIG. 2, the drainage mounting structure according to the present embodiment includes a foundation 1, an outer wall panel 10 arranged on the foundation 1 with a space therebetween, and a pillar 16 installed on the foundation 1. And the foundation drainer 20 arrange | positioned along the edge of the foundation 1 and the drainer attachment 5 for attaching the foundation drainer 20 are provided. In the present embodiment, it is assumed that the edge of the foundation 1 extends straight along the outer periphery of the building. In FIG. 2, a direction parallel to the edge of the foundation 1 is indicated by an arrow A1, and this direction is hereinafter referred to as a “width direction”. In addition, a direction orthogonal to the width direction on the horizontal plane is indicated by an arrow A2, and this direction is hereinafter referred to as a “front-rear direction”. The width direction and the front-rear direction coincide with the lateral width direction and the thickness direction of the outer wall panel 10, respectively. In the front-rear direction, the external space (outdoor) side is the front, and the internal space side is the rear.

  As shown in FIG. 1, the outer wall panel 10 includes a first wall member 11, a second wall member 12, and a heat insulating material 14 from the outer space side. A lower end portion of the heat insulating material 14 is disposed in the panel frame 15. A first air passage 31 is formed between the first wall member 11 and the second wall member 12 of the outer wall panel 10 for moisture prevention. In addition, a second ventilation path 32 extending under the floor is formed between the foundation 1 and the outer wall panel 10 (panel frame 15). The base drainer 20 functions as a ventilation member that sends outside air into both the first ventilation path 31 and the second ventilation path 32 in a normal state. Therefore, the base drainer 20 includes an outside air inlet 21 for taking in outside air from below, a first ventilation path 41 extending from the outside air inlet 21 to the first ventilation path 31, and a second ventilation path from the outside air inlet 21. And a second ventilation path 42 extending to 32. The base drainer 20 is formed, for example, by arranging a plurality of drainage parts having a predetermined length as shown in FIG. 8 adjacent to each other in the longitudinal direction. A specific shape example of the foundation drainer 20 will be described later.

  In the present embodiment, the lower end portion of the outer wall panel 10 is placed on the panel receiving member 60 fixed to the column 16. More specifically, the panel frame 15 that supports the outer wall panel 10 from below is placed on the panel receiving member 60. The pillars 16 have a rectangular cross section, and are arranged at intervals along the width direction. The panel receiving member 60 is provided for every pillar 16, for example, and the two bolts 52 are penetrated by each. The bolt 52 is a height adjusting bolt, and the height of the panel receiving member 60 is adjusted by a nut 56 attached to the bolt 52. Since the bolt 52 extends in the vertical direction on the foundation 1, in this embodiment, the foundation drainer 20 is attached using the bolt 52.

  However, when the front surface of the column 16 is not installed parallel to the edge of the foundation 1, the alignment direction of the two bolts 52 is inclined with respect to the edge of the foundation 1. Therefore, when the support member that supports the foundation drainer 20 is straightly fixed to the bolts 52 that are inclined, the support member itself is also inclined, so that the foundation drainer 20 can be appropriately attached. Can not. In order to cope with this, it is conceivable that a loose hole for the bolt 52 is formed in the support member so that the position of the support member can be adjusted in all directions. This is not desirable because the position will be crazy.

  On the other hand, the drainage fixture 5 according to the present embodiment can appropriately attach the foundation drainer 20 while using the bolt 52. An example of the structure of the drainer fixture 5 will be described in detail below.

<About the structure of the draining fixture>
With reference to FIGS. 1-3, the structural example of the draining fixture 5 which concerns on this Embodiment is demonstrated. FIG. 3 is a cross-sectional view showing the drainage fixture 5 according to the present embodiment.

  As shown in FIGS. 1 to 3, the drainage fixture 5 is disposed on the outer space side of the column 16. The drainage fixture 5 includes a column fixing member 6 that is fixed to the column 16, and a support member 8 that is attached to the column fixing member 6 so as to be adjustable in angle and supports the foundation drainer 20.

  The column fixing member 6 includes the panel receiving member 60 and bolts 52 and a base member 7 placed on the foundation 1. The bolts 52 fixed to the panel receiving member 60 are arranged so as to press the bottom wall 71 of the base member 7 onto the foundation 1. Thereby, the base member 7 is indirectly fixed to the column 16. The base member 7 and the support member 8 are rotatably connected by a connecting shaft 54. The connecting shaft 54 is arranged at a position equidistant from the axis of the two bolt shafts 53.

  The panel receiving member 60 has an L-shaped cross section, and includes a placement portion 61 on which the panel frame 15 is placed, and a column contact portion 62 that contacts the side surface (front surface) of the column 16. Has been. The mounting portion 61 is formed with two through holes 61 a and 61 b for inserting a shaft portion (hereinafter referred to as “bolt shaft”) 53 of the bolt 52. For example, one through hole 62 a is formed in the column contact portion 62. The panel receiving member 60 is fixed to the column 16 by passing a fastener such as a screw 51 through the through hole 62 a and the side surface of the column 16.

  The structures of the base member 7 and the support member 8 will be described with further reference to FIGS. FIG. 4 is an exploded perspective view showing the base member 7 and the support member 8. FIG. 5 is a view showing an attachment state of the base member 7 and the support member 8. FIG. 6 is a view showing an angle adjustment range of the support member 8. As shown in FIG. 5, the support member 8 and the base member 7 (that is, the two bolt shafts 53) are arranged straight without adjusting the angle of the support member 8 with respect to the base member 7. The arrangement position is referred to as “standard position”.

  As shown in FIGS. 1 to 4, the base member 7 includes, for example, a bottom wall 71 disposed on the foundation 1, a standing wall 72 that rises above the rear end of the bottom wall 71, and an upper end portion of the standing wall 72. It has an upper wall 73 that extends further forward and a standing wall 74 that rises upward from the front end of the bottom wall 71. Arc-shaped notches 75 and 76 for receiving the two bolt shafts 53 are formed at the front end of the upper wall 73. As shown in FIG. 5, the radius of curvature of the notches 75 and 76 of the base member 7 is substantially the same as the radius of the bolt shaft 53. Therefore, the side surfaces of the notches 75 and 76 always function as contact portions (inner contact portions) that contact the bolt shaft 53. A through hole 73 a through which the connecting shaft 54 is inserted is formed in the upper wall 73 at a position equidistant from the notches 75 and 76.

  The support member 8 includes, for example, a plate-like horizontal plate portion 81 that extends in the horizontal direction, and a plate-like attachment portion 82 that is connected to the front side end portion of the horizontal plate portion 81 and extends in the vertical direction. Yes. The horizontal plate portion 81 is disposed so as to overlap the upper wall 73 of the base member 7. The front end portion of the horizontal plate portion 81 is placed on the standing wall 74. Arc-shaped notches 84 and 85 for receiving the two bolt shafts 53 are also formed in the horizontal flat plate portion 81. The curvature radius of the notches 84 and 85 of the support member 8 is larger than the radius of the bolt shaft 53. Therefore, the support member 8 can be rotated within a predetermined range around the connecting shaft 54. A through hole 81 a into which the connecting shaft 54 is inserted is formed at a position equidistant from the notches 84 and 85.

  On the side surface (arc surface) side of the notches 84 and 85 of the horizontal flat plate portion 81, a contact portion (outer contact portion) 86 that contacts the outer peripheral surface of the bolt shaft 53 within the rotation range of the support member 8. , 87 are preferably formed. The contact portions 86 and 87 are preferably located on the circumscribed circle C1 shown in FIG. The “circumferential circle” represents the outer circle C <b> 1 of the two circles C <b> 1 and C <b> 2 that contact the outer peripheral surface of the bolt shaft 53 with the connecting shaft 54 as the center. The contact portions 86 and 87 protrude upward from the upper surface of the horizontal plate portion 81, for example. In consideration of the play of the through holes 73a and 81a into which the connecting shaft 54 is inserted, the contact portions 86 and 87 have contact surfaces between the axis of the connecting shaft 54 and the axis of the bolt shaft 53. You may form so that it may become 90 degrees with respect to the straight line to connect.

  For example, the attachment portion 82 extends downward from the front end portion of the horizontal plate portion 81. On the one end side and the other end side in the width direction of the mounting portion 82, through holes 82a and 82b through which screws 55 (FIG. 1) as fasteners are inserted are formed. In addition, when the foundation drainer 20 is constituted by a plurality of drainage parts, the end portions of two adjacent drainage parts may be fixed to the attachment portion 82, respectively. That is, a screw 55 that passes through one end portion in the longitudinal direction of the first draining part (through hole 25b shown in FIG. 8) passes through one through hole 82a, and a second draining hole 82b passes through the other through hole 82b. A screw 55 may be passed through the other end in the longitudinal direction of the component (through hole 25a shown in FIG. 8).

  In the present embodiment, as described above, since the notches 84 and 85 are formed in the support member 8, the range of the angle of the support member 8 with respect to the base member 7 can be regulated. More specifically, as shown by the solid line in FIG. 6, when the support member 8 is rotated to one side, the outer peripheral surface of the bolt shaft 53 and a part of the side surface of the notch 85 are in contact with each other. Further rotation is restricted. Further, as shown by the one-dot chain line in FIG. 6, when the support member 8 is rotated to the other side, the outer peripheral surface of the bolt shaft 53 and a part of the side surface of the notch portion 84 are in contact with each other. The above rotation is restricted. As shown in FIG. 6, in the present embodiment, the angle of the attachment portion 82 of the support member 8 can be changed by, for example, a maximum of 5 °. That is, the support member 8 can be adjusted by about 2.5 ° in both directions from the standard position.

  Thus, the adjustment of the support member 8 can be facilitated by restricting the range of the rotation angle of the support member 8. Moreover, even if some external pressure is applied to the support member 8 after the base drainer 20 is attached to the drainer fixture 5, it is possible to avoid the support member 8 from being greatly distorted.

  FIGS. 7A to 7C are diagrams schematically showing the positional relationship between the installation angle of the pillar 16 and the support member 8 when the drainage fixture 5 according to the present embodiment is used. In FIG. 7, the edge of the foundation 1 is indicated by a one-dot chain line. Referring to FIG. 7A, when the column 16 is installed parallel to the edge of the foundation 1, the two bolt shafts 53 are also aligned straight in the width direction, so that the base member 7 is Arranged parallel to the edge. Therefore, in this case, the support member 8 is appropriately arranged while remaining in the standard position.

  On the other hand, as shown in FIGS. 7B and 7C, when the pillar 16 is twisted and installed on the foundation 1, the two bolt shafts 53 are also aligned obliquely with respect to the width direction. Therefore, the base member 7 is also inclined with respect to the edge of the foundation 1. However, in this embodiment, since the support member 8 is rotatable, the operator adjusts the angle of the support member 8 so that the mounting portion 82 of the support member 8 is parallel to the edge of the foundation 1. can do. That is, the mounting portion 82 can be disposed at an appropriate position by rotating the support member 8 from the standard position to either one.

  As described above, according to the present embodiment, even when the column 16 is twisted and attached to the foundation 1, the foundation drainer 20 can be attached in parallel to the edge of the foundation 1. Therefore, even when the foundation drainer 20 is composed of a plurality of drainer parts, the drainer parts can be attached without gaps. As a result, it is possible to prevent rainwater from entering from the gaps between the draining parts. Moreover, the aesthetics of the whole foundation drainer 20 can be improved.

  Further, regardless of the angle of the support member 8 with respect to the base member 7, the bolt shaft 53 has the side surfaces of the notched portions 75 and 76 of the base member 7 and the contact portions 86 and 87 of the support member 8. It is sandwiched between. Therefore, although the base member 7 is only pressed on the foundation 1 by the bolts 52, it is possible to prevent the base member 7 from being displaced on the foundation 1. Therefore, it is possible to prevent the base member 7 and the support member 8 from shifting in the front-rear direction. As a result, the distance between the side surface of the foundation 1 and the foundation drainer 20 (that is, the position in the exit direction of the foundation drainer 20) can be made uniform.

  The base member 7 is provided with arc-shaped notches 75 and 76 for receiving the bolt shaft 53. However, the base member 7 and the bolt shaft 53 are at least inscribed circle C2 shown in FIG. It suffices that the points (lines) positioned above abut each other. The “inscribed circle” represents the inner circle C <b> 2 of the two circles C <b> 1 and C <b> 2 that contact the outer peripheral surface of the bolt shaft 53 with the connecting shaft 54 as the center.

<About draining the foundation>
Next, a shape example and an arrangement example of the foundation drainer 20 in the present embodiment will be described.

  FIG. 8 is a perspective view showing the shape of the foundation drainer 20 in the present embodiment. FIG. 9 is a cross-sectional view of the foundation drainer 20 when cut along the line XI-XI in FIG. 8. The base drainer 20 is formed by arranging drainage parts having a predetermined length as shown in FIG. 8 in the longitudinal direction.

  Referring to FIGS. 1, 8, and 9, foundation drainer 20 in the present embodiment includes a front standing wall portion 22, a bottom wall portion 23, a front side wall portion 24, a rear standing wall portion 25, and an upper wall portion. 26, an inclined portion 27, and a rear side wall portion 28. The front standing wall portion 22 extends in the vertical direction and includes a plurality of rectangular outside air inlets 21. The outside air inlet 21 is covered with, for example, a mesh material. The bottom wall portion 23 is located in front of the lower end portion of the front standing wall portion 22 and extends in a substantially horizontal direction. The front side wall portion 24 rises above the front side end portion of the bottom wall portion 23, and comes into contact with the lower surface of the lower end portion of the first wall member 11 of the outer wall panel 10. The lower end of the first wall member 11 is located below the lower ends of the second wall member 12 and the panel frame 15 and above the upper surface of the foundation 1.

  The rear vertical wall 25 extends substantially parallel to the front vertical wall 22 on the rear side of the front vertical wall 22, and through holes 25 a and 25 b for inserting screws 51 are provided at one end and the other end in the longitudinal direction, respectively. It has been. That is, the foundation drainer 20 is attached along the edge of the foundation 1 by fixing the rear vertical wall 25 to the support member 8 of the drainage fixture 5. The rear vertical wall portion 25 is attached so that the through hole 25a fits the through hole 82b (FIG. 2) of the attachment portion 82 in the support member 8 of the drainage fixture 5, and the through hole 25b has a different drainage fixture 5. It attaches so that it may fit in the through hole 82a (FIG. 2) of the attaching part 82 in the support member 8 of this.

  The upper wall portion 26 connects the upper end portion of the front standing wall portion 22 and the upper end portion of the rear standing wall portion 25 and extends in a substantially horizontal direction. The inclined portion 27 extends obliquely upward from the lower end portion of the rear vertical wall portion 25 toward the rear side. The rear side wall portion 28 rises above the rear side end portion of the inclined portion 27 and comes into contact with the side surface of the foundation 1.

  Here, it is desirable that the drainage mounting structure including the outer wall member (outer wall panel 10) has a negative pressure generating structure by arranging the base drainer 20 having such a shape as shown in FIG. In addition, the outer wall ventilation structure provided with the negative pressure generating structure has been filed as Japanese Patent Application No. 2013-008269.

  The “negative pressure generating structure” is the first ventilation path 31 through the first ventilation path 41 for the outside air taken in from the outside air inlet 21 when the wind speed in the vicinity of the outer wall panel 10 becomes a predetermined value or more. Is a structure in which a negative pressure is generated so that air in the second ventilation path 42 is directed toward the first ventilation path 41. The negative pressure generating structure desirably generates a negative pressure when the wind speed is 10 m / s, but it is sufficient that the negative pressure is generated at least when the wind speed is 15 m / s.

  That is, as the first negative pressure generating structure, as shown in FIG. 1, the first ventilation path 41 from the outside air inlet 21 to the first ventilation path 31 becomes a substantially straight main path, and the outside air inlet 21. The foundation drainer 20 is arranged so that the second ventilation path 42 extending from the first to the second ventilation path 32 becomes a branch path that branches to the side. More specifically, the outside air inlet 21 of the base drainer 20 is vertically disposed almost directly below the front side (external space side) surface of the second wall member 12, and the bottom wall 23 and the upper wall The wall portion 26 is attached so as to be parallel to the upper end surface of the foundation 1. Thereby, the 1st ventilation path 41 is made into the main path | route. Therefore, as shown by an arrow F11 in FIG. 1, in the normal time, the outside air taken in from the outside air inlet 21 heads toward the first ventilation path 41 positioned substantially linearly upward, and the second ventilation is provided in the middle. Branch to path 42.

  Further, as shown in FIG. 1, the second negative pressure generating structure is such that the inlet dimension L2 of the second ventilation path 32 is smaller than the inlet dimension L1 of the first ventilation path 31. A drainer 20 is arranged. In the present embodiment, the dimension L2 indicates the distance between the upper wall portion 26 of the base drainer 20 and the lower end portion of the outer wall panel 10 (second wall member 12) positioned immediately above the upper wall portion 26. In addition, the inlet dimension L2 of the 2nd ventilation path 32 in this Embodiment shall be more than the lower limit for ensuring the predetermined ventilation volume in normal time.

  Further, as the third negative pressure generating structure, the front standing wall portion 22 of the foundation drainer 20 is formed and arranged so as to also serve as a partition wall that provides resistance to the flow of outside air to the second ventilation path 42. Specifically, as shown in FIGS. 8 and 9, the outside air inlet 21 is formed excluding a part of the upper side of the front vertical wall portion 22 (hereinafter referred to as “upper side surface”) 220. The upper side surface 220 serves as a partition wall by being present at an angle with respect to the flow of outside air to the second ventilation path 42. In the present embodiment, the front standing wall portion 22 also serves as a partition wall. However, for example, a dedicated partition wall may be provided on the rear side of the front standing wall portion 22.

  In the present embodiment, by adopting the first to third negative pressure generating structures, it is possible to prevent rainwater from entering the second ventilation path 32 even during strong winds.

  FIG. 10 is a diagram showing an air flow during strong wind in the drainage mounting structure according to the embodiment of the present invention. Referring to FIG. 10, it is assumed that the weather in the vicinity of the building having the drainage mounting structure according to the present embodiment is strong wind and raining. In that case, the strong wind containing rainwater is sent to the first ventilation path 31 via the first ventilation path 41 in a flow as indicated by an arrow F12. Further, since negative pressure is generated on the second ventilation path 32 side, the air in the second ventilation path 42 is sent to the first ventilation path 41 side in a flow as indicated by an arrow F13. The air in the second ventilation path 42 sent to the first ventilation path 41 side is drawn into the first ventilation path 31 together with the outside air (strong wind including rainwater) taken in from the outside air inlet 21. Therefore, the inflow of rainwater to the second ventilation path 32 is prevented.

  In addition, if the drainage attachment structure which concerns on this Embodiment has the said 1st-3rd negative pressure generation | occurrence | production structure, the shape and arrangement position of the foundation drainer 20 are not limited to the said example. For example, the outside air intake 21 may be formed in the bottom wall portion 23. In that case, the foundation drainer 20 may be inclined and arranged so that the bottom wall portion 23 faces obliquely forward.

  Moreover, in the draining attachment structure which concerns on this Embodiment, the said 1st-3rd negative pressure generation structure was employ | adopted. However, it is not necessary to adopt all of these, and if at least a negative pressure is generated on the second air passage 32 side at a wind speed of 10 m / s, only one of these may be employed. Good.

  Moreover, it is not limited to the said 1st-3rd negative pressure generation structure, Furthermore, you may employ | adopt another negative pressure generation structure. For example, the flow resistance that enters the second ventilation path 32 via the second ventilation path 42 is made larger than the flow resistance that enters the first ventilation path 31 via the first ventilation path 41. Also good. Specifically, a mesh material or the like may be disposed in the vicinity of the entrance of the second ventilation path 32, that is, in the whole or a part of the gap indicated by the dimension L2 in FIG.

<Other examples of draining fixtures>
In the above embodiment, it is assumed that the column fixing member 6 of the drainage fixture 5 includes the panel receiving member 60 fixed to the column 16, but the panel receiving member 60 may not be included. That is, the column fixing member 6 may be configured by the base member 7 and the plurality of bolts 52. In this case, the plurality of bolts 52 may not have the function of adjusting the height of the panel frame 15 as in the above embodiment. Further, the base member 7 may be directly fixed to the column 16.

  When the base member 7 is directly fixed to the column 16, the number of bolts 52 included in the column fixing member 6 may be one. A structural example of the drainage fixture 5 in this case will be described as a modification of the present embodiment with reference to FIG.

  FIG. 11: is a schematic diagram which shows the structural example of the base member 7A and the supporting member 8A which are contained in the draining fixture 5 which concerns on the modification of embodiment of this invention, (A)-(C) has a pillar. The positional relationship between 16 installation angles and the support member 8A is schematically shown. Also in FIG. 11, the edge of the foundation 1 is indicated by a one-dot chain line.

  Referring to FIG. 11A, in the modification, base member 7A is attached to column 16 by, for example, a connecting member (not shown) so as to be arranged in parallel with the front surface of column 16. The upper wall 73 of the base member 7 </ b> A includes one notch 77 that receives one bolt shaft 53 instead of the two notches 75 and 76. The notch 77 basically has the same function as the notches 75 and 76.

  The horizontal plate portion 81 of the support member 8 </ b> A includes one elliptical receiving hole 88 for receiving one bolt shaft 53 instead of the two notches 84 and 85. The shaft center of the connecting shaft 54 and the center of the receiving hole 88 are both located at the center in the width direction of the horizontal plate portion 82. The receiving hole 88 is formed such that a part of the arc surface on the front side is located on the circumscribed circle of the connecting shaft 54. Thereby, a part of the side surface of the receiving hole 88 functions as a contact portion 86A that contacts the outer peripheral surface of the bolt shaft 53 within the rotation range of the support member 8A.

  Also in this modified example, as shown in FIG. 11A, when the column 16 is installed in parallel to the edge of the foundation 1, the base member 7A is also arranged in parallel to the edge of the foundation 1. . Therefore, in this case, the support member 8A is appropriately disposed while remaining in the standard position.

  On the other hand, as shown in FIGS. 11B and 11C, when the column 16 is twisted and installed on the foundation 1, the base member 7 </ b> A is also the same as the column 16 with respect to the edge of the foundation 1. They are offset by an angle. Therefore, also in this case, the angle of the attachment portion 82 of the support member 8A is adjusted in parallel to the edge of the foundation 1 by rotating the support member 8A from the standard position to either one. Thereby, also in this modification, the foundation drainer 20 can be attached in parallel to the edge of the foundation 1 regardless of the installation angle of the column 16.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
