  Non-Patent Document 1 discloses an air supply / exhaust louver attachment structure attached to an outer wall. According to this Non-Patent Document 1, the main body of the louver is fixed to the inside of the opening provided in the outer wall with an anchor, and then the space between the inner peripheral surface of the outer wall and the outer frame of the louver from the room and the outer wall side. Plasterer filling with mortar.

  Moreover, in FIG. 2 of patent document 1, the attachment structure of the ventilation port which can be constructed from the inner side of a wall is disclosed. A ventilation port mounting structure 100 shown in FIG. 5 includes a vent cap 101 and a flange 102 extending outward from the outer peripheral surface of the vent cap 101. On the other hand, an outer wall 103 to which the vent cap 101 is attached is provided with an opening 104 provided in the outer wall 103 and a fixing device base 105 on the inner surface side of the wall 103 so as to correspond to the opening 104. In the ventilation port mounting structure 100, first, the vent cap 101 is inserted into the opening 104 from the indoor side of the wall 103. Next, the dowel-shaped gasket 106 is interposed and sealed on the contact surface where the flange 102 collides with the inner surface of the outer wall. Then, with the flange 102 pressed against the gasket 106 as it is, it is fixed to the fixing device base 105 of the wall 103 by a fixture 107 or the like that penetrates the flange 102.

  The gallery main body 110 disclosed in Patent Literature 2 includes a gallery blade 111 and a mounting frame (stand) 114 that supports the gallery blade 111 and is fixed inside the opening 113 provided in the building housing 112. Consists of. The stand 114 is a vertically long member having a U-shaped cross section. At the upper and lower ends of the stand 114, plate-like mounting brackets 115 bent at a right angle for fixing the main body 110 to the opening 113 are arranged. An anchor 116 is driven into the inner peripheral surface of the opening 113 at a position corresponding to the mounting bracket 115. And the said gallery main body 110 is attached by fastening the volt | bolt 117 to the anchor 116 provided in the opening part 113 via the attachment metal fitting 115. FIG. In addition, a gasket 118 attached to the louver blade 111 is disposed in a gap portion between the louver blade 111 and the opening 113 to prevent intrusion of rainwater. Furthermore, the lower end portion of the opening 113 is formed with an inclined surface 119 in which the building housing 112 itself is inclined downward, and has a structure for discharging rainwater to the outside.

  In the prior art, a method is used in which the louver is fixed to the inner surface of the opening with an anchor bolt, and both the anchor bolt and the anchor bolt are filled with mortar at a stretch from the inside and outside of the outer wall. Therefore, when installing a louver or a ventilation port, a scaffold is set up on the outer wall surface, assembled from the outer wall side, mortar filled, and then caulked. Such a construction method requires a dangerous work on an external scaffold in a high-rise building, and costs and labor are also required.

  Moreover, the vent cap 101 of patent document 1 can be constructed from the indoor side. However, since the structure for sealing the rain relies only on the gasket provided on the indoor side, if the square duct with a larger opening is used, the sealing area increases, so the sealing part must be tightly sealed. I can't. Further, when trying to seal the gap between the vent cap 101 and the opening, a caulking material or the like must be filled from the outside of the wall.

  In the gallery of patent document 2, since the outer wall is slanted so that the inside of an opening may be inclined for drainage of rainwater, the labor concerning the construction is large. In addition, since a large number of anchors are installed on the inner peripheral surface of the opening to fix the vertical, it cannot be easily assembled.

  An object of the present invention is to provide a louver attachment structure that can seal louvers from the inside and outside of a wall and that can perform all such sealing operations from the indoor side.

  The louvering attachment structure of the present invention (Claim 1) is a louvering attachment structure for attaching a louver for ventilation between indoors and outdoors to an outer wall, and a frame fitted into an opening provided in the outer wall. A body, a draining plate provided inside the frame and inclined so as to descend from indoors to the outdoors, and a louver provided on the draining plate in the frame and having a frame portion for locking the blades The drainage port which consists of a main body and inclines toward the downward direction between the said frame part and a draining board is characterized by the above-mentioned.

  As for such a louver attachment structure, it is preferable that the draining plate protrudes downward from the lower end of the opening portion to the outside (Claim 2). In addition, it is preferable that a drain hole that communicates with the drain port is provided at a lower portion of the frame portion.

  The louver attachment structure of the present invention (Claim 1) is composed of three parts: a frame, a draining plate, and a louver main body. For this reason, when the frame is first inserted into the opening, the inside of the opening of the frame is wide open and leads to the outdoors. That is, the opening can be used as a work space. In other words, thanks to the space, the body and the tool can be freely used, so that the gap between the frame and the outer wall can be easily filled with a caulking material or the like from the outdoor side and sealed. Next, when the draining plate and the louver main body are inserted into the attached frame body, the louver main body and the draining plate can be sealed from the frame body and the indoor side. Then, the louver can be sealed from both the outdoor and indoor sides of the outer wall only by work from the indoor side.

  Further, when the three parts are assembled, a drainage opening is formed by the frame part and the draining plate. Therefore, it is possible to omit the work of forming the opening of the outer wall separately and obliquely. In other words, when the window on the outer wall is used as an opening for the glazing after modification or the like, the glazing can be easily attached.

  Moreover, when the said draining board protrudes below toward the outdoors from the lower end of an opening part (Claim 2), it prevents that the rain water discharged | emitted from the lower side of a frame enters again. Furthermore, when a drain hole that communicates with the drain outlet is provided at the lower portion of the frame portion (Claim 3), rainwater that has entered the louver can be reliably discharged to the outdoors.

  Next, an embodiment of the louver mounting structure of the present invention will be described with reference to the drawings. FIG. 1 is a side sectional view of a louver mounting structure of the present invention, FIG. 2a is a slope view showing a louver main body, FIG. 2b is a slope view showing a frame body, FIG. 2c is a slope view showing a drain plate, and FIG. Fig. 3b is a schematic view showing the state of attaching the draining plate, Fig. 3c is a schematic view showing the state of attaching the galley body, Fig. 4a is a cross-sectional view taken along line XX of Fig. 3b, and Fig. 4b is a diagram. A cross-sectional view taken along line YY of 3c is shown.

  First, an embodiment of the louver mounting structure of the present invention will be described with reference to FIG. The louver attachment structure A in FIG. 1 includes a louver main body 1 disposed in an opening W provided in an outer wall G, and an outer periphery and an opening W of the louver 1 for fixing the louver main body 1 inside the opening W. A frame body 4 interposed between the inner peripheral surface of the frame body 4 and a draining plate 5 disposed between the frame body 4 and the lower portion of the gallery main body 1 and inclined from the indoor side toward the outdoor side; Consists of. In addition, it is preferable to use a steel material or an aluminum material having corrosion resistance against rain water such as stainless steel for the louver mounting structure A.

  Next, each part is demonstrated in detail using the slope view of FIG. The gallery main body 1 shown in FIG. 2a includes a duct short pipe 2 that forms a frame-like communication path for ventilating air between indoors and outdoors, and an end portion on the outdoor side of the inner peripheral surface of the duct short pipe 2 And blades 3 that are inclined so as to have a lower edge toward the outside and are fixed in a row in parallel up and down.

  The duct short pipe 2 has an indoor side, a ridge 2a bent vertically from the end to the outside, and a surface 2d corresponding to the lower side inside the frame when installed in the opening W. A wall 2b extending vertically is provided. Further, a drain hole 2c is formed in the lower surface 2d on the outdoor side of the wall 2b. The flange 2a is a part for connecting another duct that guides the short duct 2 to the indoor side. Further, the drain hole 2c, together with the wall 2b, blocks rainwater that has entered from the gap between the blades 3 to the inside of the duct short pipe 2 with the wall 2b, and further drains the drain from the drain hole 2c to the outside. It prevents rainwater from entering indoors.

  The blades 3 are plate-like members that are fixed in a line in the vertical direction near the end of the short duct 2 on the outdoor side. The blades 3 regulate the air flow and infiltrate rainwater into the duct short pipe 2. To prevent.

  Next, the frame 4 shown in FIG. 2b will be described. The frame body 4 is a frame-shaped member along the inner peripheral surface of the opening W provided in the outer wall G. The frame body 4 includes a side wall 4a that forms a frame shape, and a bracket 4b that extends perpendicularly outward from the indoor side end of the side wall 4a and contacts the indoor side surface of the outer wall G. A fixing hole 4c for fixing the frame 4 to the outer wall G is formed in the bracket 4b.

  Next, the draining plate 5 shown in FIG. 2c will be described. The draining plate 5 is a plate-shaped member, and includes an inclined surface 5a inclined downward from the indoor side toward the outdoor side, and a bracket 5b that bends the inclined surface 5a and contacts the indoor side surface of the outer wall G. . The bracket 5b is provided with a fixing hole 5c for fixing the draining plate 5 to the outer wall G. Since the fixing holes 5c are provided so as to have the same pitch as the fixing holes 4c for locking the frame body 4 to the outer wall G, both members can be fixed to the outer wall together.

  Next, how the frame body 4 is inserted into the outer wall G will be described with reference to FIG. First, the hole-in anchor 6 is driven by the instrument K at a position corresponding to the pitch of the fixing holes 4c provided in the frame 4 around the opening W shown on the left side in FIG. If it does so, it will become a base for fastening frame 4 with fastener B etc.

  Before the frame body portion of the frame body 4 is fitted toward the opening W, an elastic backup material 7 is attached to the outer periphery of the front end portion of the frame body 4. The backup material 7 is affixed to the indoor side by a predetermined amount from the front end of the frame body 4 and is fitted into the opening W as it is. Next, the bracket 4b is brought into contact with the inner surface of the outer wall G, and is fixed to the outer wall G from the fixing hole 4c by a fastener B such as a bolt or a screw (see FIG. 3b). The backup material 7 is an elastic rubber-like material.

  Next, FIG. 4a shows an XX cross-sectional view of FIG. 3b. As shown in FIG. 4 a, the distal end portion on the outdoor side of the frame body 4 is in close contact with and in contact with the elasticity of the backup material 7, and the frame body 4 is locked to the inner peripheral surface of the opening W. The backup material 7 is arranged so as to be recessed from the front end of the frame 4 toward the indoor side by a predetermined amount. Therefore, at the time of insertion into the opening W, a gap 8 surrounded by the frame 4, the backup material 7, and the inner peripheral surface of the opening W is formed. Next, the caulking material 9 is filled along the outer periphery of the frame body 4 by reaching into the gap 8 from the indoor side.

  Even if the frame 4 is inserted into the opening W in this way, the caulking material 9 can be easily filled and sealed from the outdoor side by extending the body or tool from the indoor side through the large opening space.

  Next, how the draining plate 5 is attached will be described with reference to FIG. First, the slope portion 5a is arranged on the lower surface 2d of the frame body 4 so as to be inclined from the indoor side toward the outdoor side. Then, the bracket 5 b that is continuous with the inclined surface portion 5 a is brought into contact with the inner surface of the outer wall G. Next, the fixing hole 5c of the bracket 5b is arranged so as to overlap the fixing hole 4c of the frame body, and the frame body 4 and the draining plate 5 are fixed by a fastener B such as a common bolt. Thereafter, the caulking material 9 is filled from the indoor side into the gap between the slope portion 5a and the inner periphery of the frame body 4 and sealed (see FIG. 3c).

  At that time, as shown in FIG. 4b, the inclined portion 5a of the draining plate 5 is arranged in a state of protruding a predetermined amount from the lower end portion of the opening W toward the outdoor side. At this time, the end portion of the slope portion 5a is disposed below the lower end of the opening W (reference numeral L in FIG. 4b). If it does so, even if rain water penetrate | invades into the inside of the frame 4, it can be made to drain | drain to the outdoors along the said slope part 5a reliably. Further, it is possible to prevent rainwater from entering the gap 5d formed between the slope 5a formed by providing the slope 5a on the lower surface 2d and the inner bottom surface of the frame body 4.

  Next, as shown in FIG. 3 c, the upper surface side and the side surface side of the duct short tube 2 of the gallery main body 1 are inserted so as to be in contact with the upper surface and side surfaces inside the frame body 4. At this time, the lower surface side of the duct short tube 2 is in contact with the bent portion (P in FIG. 3c) located at the uppermost position of the slope portion 5a.

  Next, as shown in FIG. 1, when the duct short pipe 2 is inserted between the frame body 4 and the draining plate 5, the duct short pipe 2 is directed to the outdoor side between the inclined surface portion 5 a on the lower surface side. A drain port 10 extending downward is formed. The drainage port 10 and the louver main body 1 communicate with each other through the drain hole 2c and are separated from the indoor side. At this time, the drain hole 2c is arranged on the outdoor side from the bent portion P. Then, the caulking material 9 is piled up and sealed from the indoor side at the corner formed by the duct short tube 2 and the surface of the flange 2a of the frame body 4. On the other hand, on the lower surface of the duct short pipe 2, the caulking material 9 is placed and sealed from the indoor side at the corner formed by the duct short pipe 2 and the bracket 5b.

  If it does so, even if rain water penetrate | invades into the inside of a gallery main body 1 temporarily exceeding the said blade | wing 3, the attached gallery main body 1 will be blocked | interrupted by the said wall 2b, and cannot reach an indoor side. Furthermore, it flows into the drainage port 10 from the drain hole 2c, is guided to the outdoors through the slope portion 5a.

  The louver attachment structure A shown in FIG. 1 can perform all the operations for sealing the louver main body 1 with a caulking material or the like from the indoor side and the outdoor side from the indoor side. Therefore, in the renovation work of the building, the gallery main body 1 can be easily attached without newly forming a scaffold on the outdoor side of the outer wall, and the work can be performed safely. Further, when the three parts are assembled, a drainage opening is formed by the frame part and the draining plate. For this reason, the opening of the outer wall may be horizontal, and it is possible to omit the work of cutting obliquely separately. In other words, when the window on the outer wall is used as an opening for the glazing after modification or the like, the glazing can be easily attached. Furthermore, since it is divided into the three parts of the louver main body 1, the frame body 4, and the draining plate 5, when replacing any one part, it is not necessary to remove all.
