Description

  The present invention relates to a vent drainer attached to a waist wall such as a balcony.

  In order to raise the grade of measures against deterioration of buildings, some kind of hut ventilation system is required for balconies (including rooftops) that are handled as roofs. If the method involves some risk of water leakage, it is possible to ventilate through the ventilation gallery or behind the caps, but in order to bring the risk of water leakage to zero as much as possible from the perspective of long-term durability, a high-dimensional water stoppage is required. A ventilator was needed. The corresponding conventional technology has an independent ventilation opening on the wall near the balcony, which affects the design, becomes a stepping stone because protrusions are unavoidable, is difficult to replace within the wall, and is expensive It had the aspect of being.

  In the building, a draining structure for preventing water from entering the wall is provided between the outer wall material and the base. A common draining structure is provided with a draining sheet metal projecting from between the outer wall material and the base, and this draining sheet metal is deteriorated by exposure to wind and rain. For this reason, there exists a structure which made it removable so that it can replace | exchange when draining deteriorates (for example, refer patent documents 1-4). At the time of removal, conventionally, the end portion of the sheet metal-like draining plate is deformed and removed from the draining plate fixing portion.

  In addition, there is a vent drainer in which a vent hole is formed in the space between the outer wall material on which the drainer is installed and the base so that the vent performance is provided (see, for example, Patent Documents 2 to 6). Such a drainage drain is excellent in that it has ventilation performance, but there is a problem that rainwater enters from the vent hole due to rainwater blowing. For this reason, there exists what attached the valve to the vent hole so that rainwater may not enter from the vent hole (for example, refer to patent documents 5 to 6).

  However, in Patent Documents 1 and 2, there is a problem that the assembly work is troublesome because it is necessary to pass through the spring-type stationary body (mounting bracket) and to be attached with individual screws. In Patent Documents 3 and 4, for ventilation, it is necessary to provide a vent hole in the draining main body and the fixed base, and each of them generally requires equipment such as a press die, which is manufactured by processing to open the vent hole. There was a problem that could not be easily done. In Patent Documents 5 and 6, it is desirable that the on-off valve can be easily replaced from the viewpoint of durability.

  It is an object of the present invention to provide a ventilating drainer that prevents rainwater from entering when maintenance is easy and wind and rain are strong.

A typical configuration of the present invention for achieving the above object is as follows.
A vent drainer attached to the outside of the vent hole between the exterior material and the base,

(Schematic configuration of venting drainer 1)
First, a schematic configuration and a peripheral configuration of the ventilating drainer 1 will be described. 1A and 1B are cross-sectional views showing the overall configuration of the ventilating drain, wherein FIG. 1A is a schematic diagram showing a place where the venting drainage is attached in a building, and FIG. FIG. 2 is a perspective view showing the entire structure of the ventilating water drainer.

  As shown in FIG. 1 (a), the ventilating drainer 1 is preferably provided inside the outer wall 4 of the balcony 3 at the upper part of the hut 5 of the building 2, for example. Since the ventilation drainer 1 has air permeability, air can be introduced from the balcony 3 to the hut back 5 while preventing rainwater from entering. In addition, the installation location of the ventilator 1 is not limited to this location.

  As shown in FIGS. 1B and 2, the ventilating drainer 1 is attached to a vent hole 8 formed between the waist wall 6 and the base 7. The vent drainer 1 has a drainer cover 10 formed with a water slice 11 inclined downward to the outside so as to keep rainwater away from the vent hole 8, and an on-off valve 12 that closes when wind blows. This configuration prevents rainwater from entering the inside of the ventilating drainer 1. Moreover, the ventilating drainer 1 has the attachment base material 20 for attaching to a wall surface. The mounting base material 20 integrally includes a placement portion 20 a placed on the base 7 and a plate-like portion 20 b fixed in the waist wall 6 rising in the direction of the waist wall 6.

  In addition, the ventilation hole 8 of this embodiment is an elongate hole located in the lowest end of the ventilation layer 8a and extending in a horizontal direction, as shown in FIG.1 (b). The ventilation layer 8a is a space formed in the back surface direction of the exterior material 6a. The ventilation layer 8a is formed between the waterproof sheet 6b on the back surface of the exterior material 6a and the waterproof layer 7b.

  The ventilating drainer 1 is attached to the waist wall 6 and the base 7. Here, the configuration of the waist wall 6 and the base 7 will be described. The waist wall 6 includes an exterior material 6 a that forms the outermost layer, a waterproof waterproof sheet 6 b, an exterior material base 6 c, and an attachment base 6 d for attaching the ventilating drainer 1. On the other hand, the base 7 has a structure in which a waterproof layer 7b made of FRP or the like is formed on the outside and upper part of the rising wall 7a made of slag gypsum board or the like.

  The exterior material base 6c preferably has the same configuration as the panel member described in, for example, Japanese Patent Application Laid-Open No. 2000-160732. In the panel member, a plurality of front side belt-like narrow plates arranged in parallel at intervals and a plurality of back side belt-like narrow plates arranged in parallel at intervals are joined and integrated in a state of crossing each other. Wall base panel is used. Such a wall foundation panel can form a ventilation layer on the back side of the outer wall finishing material that can ensure sufficient ventilation by raising the air through the space between each strip-shaped narrow plate. In addition, each band-shaped narrow plate inclined in the opposite direction is caused to function like a brace so that a desired strength as a structural strength member can be obtained. By providing the panel, the ventilation layer 8a can be formed as shown in FIG.

  Here, the method of forming the ventilation layer 8a is not limited to using such a panel. For example, as another method for forming the air-permeable layer 8a, a load bearing surface material such as a plywood or a volcanic glassy multilayer board is disposed on the back surface of the waterproof layer 7b, and a vertical trunk edge is provided between the waterproof layer 7b and the exterior material 6a. The air-permeable layer 8a may be secured using

  With this configuration, in the ventilating drainer 1, the placement portion 20a of the mounting base 20 is placed on the base 7, and the lower part thereof is fixed. Further, in the ventilating drainer 1, the plate-like portion 20b of the mounting base material 20 is sandwiched between the waterproof sheet 6b of the waist wall 6 and the exterior material base 6c, and the horizontal direction thereof is fixed. Note that the exterior material 6 a of the waist wall 6 is placed on the exterior material receiving portion 20 c of the attachment base material 20.

(Detailed structure of ventilating drainer 1)
The detailed structure of the ventilating drainer 1 will be described with reference to FIG. FIG. 3 is a cross-sectional view showing the configuration of each part of the ventilating drain, where (a) is a completed drawing of the venting drainer 1 and (b) is an exploded view of the venting drainer 1 into parts.

As shown in FIG. 3 (a), the ventilating drainer 1 is formed by connecting a draining cover 10 for preventing rainwater from entering, a mounting base material 20 for mounting on a wall surface, the draining cover 10 and the mounting base material 20, and a vent hole. And a bracket 30 for separating the drain cover 10 and the drain cover 10 from each other by a predetermined distance. The drainage cover 10, the mounting base material 20, and the bracket 30 are desirably made of a material such as aluminum that is lightweight, resistant to wind and rain, and hardly deteriorates.

  As shown in FIG. 3 (b), the drain cover 10 has a water section 11 that is inclined from the inside to the outside as it goes down.

  In addition, a fitting convex portion 13 is formed at one end that is the upper end of the water slice 11, and an on-off valve 12 is formed inside the other end that is the lower end of the water slice 11. It is desirable that the valve portion 12a of the on-off valve 12 is made by resin extrusion or the like, and the hinge portion 12b is made of a soft resin. With this structure, the valve portion 12a is opened and closed. The opening / closing operation will be described later.

  The drainer cover 10 has a bracket locking portion 14 at the inner central portion of the water slice 11 and has a structure that is locked to the bracket 30. Moreover, the member holding | maintenance part 15 opened below on the inner upper part of the water slice 11 is provided. For example, a non-flammable volumetric expansion material can be inserted into the member holding portion 15 when the ventilating drainer 1 is fireproof.

  The attachment base material 20 is a member for attaching the drainage cover 10 to the waist wall 6 and the base 7, and includes the placement portion 20a, the plate-like portion 20b, and the exterior material receiving portion 20c as described above.

  A fitting recess 21 that fits with the fitting protrusion 13 is formed on the attachment base 20 on the opposite surface of the base portion of the exterior material receiving portion 20c. A vent hole 22 communicating with the vent hole 8 formed in the waist wall 6 is formed below the fitting recess 21. The vent hole 22 is preferably a plurality of slit holes opened vertically or the like (see FIG. 4). This is to prevent a small animal such as a mouse from invading the entire longitudinal direction as an opening.

  A valve receiving portion 23 that receives the valve portion 12 a of the on-off valve 12 is formed at the lower end of the mounting base material 20. In order to attach the bracket 30, a first bracket locking portion 24 is formed above the vent hole 22, and a second bracket locking portion 25 is formed below the vent hole 22 and above the valve receiving portion 23. The

  A watertight material 41 is disposed on the lower surface of the mounting portion 20a. The watertight material 41 abuts on the base 7 and prevents water from entering into the interior from the contact between the ventilating drainer 1 and the base 7. As the material of the watertight material 41, semi-independent foamed EPDM foam having water permeability is preferable.

  The bracket 30 is composed of an overhanging portion 30a that has an inclined cross section and projects forward, a drooping portion 30b that hangs down from the front end of the overhanging portion, and an action portion 30c that engages with other members and abuts against a valve. The Since the bracket 30 is a member for connecting to other members, a plurality of claw-shaped locking portions are formed.

  A plurality of brackets 30 are arranged and fixed in the longitudinal direction of the ventilating drainer 1. One bracket 30 has at least three locking portions. First, it has the 1st latching | locking part 31 and the 2nd latching | locking part 32 latched with respect to the 1st bracket latching | locking part 24 and the 2nd bracket latching | locking part 25 of the attachment base material 20, respectively. The first locking portion 31 is formed at the rear (left side in the drawing) upper portion of the bracket 30, and the second locking portion 32 is formed at the front (right side in the drawing) lower portion of the bracket 30. Moreover, it has the 3rd latching | locking part 33 latched with respect to the bracket latching | locking part 14 of the drainage cover 10. FIG. The third locking portion 33 is formed so as to protrude forward and upward of the bracket 30.

  Moreover, it has the cushion material holding | maintenance part 34 opened upwards on the upper surface of the overhang | projection part 30a. The cushion material holding part 34 holds the cushion material 42. Then, the cushion material 42 is pressed against the drain cover 10. That is, as shown in FIG. 3A, the bracket 30 is pressed against the drainage cover 10 via the cushion material 42. As described above, the bracket 30 has the cushion material 42, so that the drainage cover 10 can be prevented from rattling or lateral displacement.

The lower part of the overhang | projection part 30a has the member holding part 35 opened below. For example, a non-combustible volume expansion material is inserted into the member holding portion 35 when the ventilating drainer 1 is fireproof.

At the lower end of the action portion 30c, a stopper 36 that abuts on the valve receiving portion 23 of the mounting base 20 is formed. Since the stopper 36 protrudes to the inside of the ventilation passage W of the ventilating drain 1 from the valve receiving portion 23, it is possible to prevent the on-off valve 12 from entering the ventilation passage W.

(Assembly of ventilation drainer 1)
The assembly of the ventilating drainer 1 will be described with reference to FIG. FIGS. 4A and 4B are perspective views showing an aeration drainage mounting configuration, in which FIG. 4A shows a state where the bracket 30 is attached to the attachment base material 20, and FIG. 4B shows a state where the drainage cover 10 is attached to the bracket 30.

  When assembling the ventilation drainer 1, first, as shown in FIG. 4A, a plurality of brackets 30 are attached to the attachment base material 20 at a predetermined interval. Next, as shown in FIG. 4B, the drain cover 10 is attached to all the brackets 30.

  Specifically, as shown in FIG. 4, first, with respect to the first bracket locking portion 24 and the second bracket locking portion 25 of the mounting base material 20, the first locking portion 31 and the second bracket locking portion 25 of the bracket 30, respectively. The two locking portions 32 are locked. Next, as shown in FIG. 4 (b), the fitting convex portion 13 of the draining cover 10 is fitted into the fitting concave portion 21 of the mounting base material 20, and the upper portion of the draining cover 10 is rotatably held. The bracket locking portion 14 of the drainage cover 10 is locked with the third locking portion 33 of the bracket 30. Thereby, the assembly work of the ventilating drainer 1 is completed. When the drain cover 10 is replaced, the operation of the drain cover 10 may be reversed.

  As described above, the ventilating drainer 1 fixes the bracket 30 to the mounting base 20 by locking. For this reason, attachment and replacement can be easily performed. Moreover, since the bracket 30 is attached to a plurality of portions in the longitudinal direction of the ventilating drainer 1, the air passage can be maintained without blocking the ventilation passage W over the longitudinal direction.

  Further, the drain cover 10 is attached to the mounting base 20 via a bracket 30 that is locked above and below the vent hole 22. For this reason, it is not necessary to arrange | position an attachment member etc. in the position which plugs the ventilation hole 22 of the attachment base material 20. FIG. For this reason, the drain cover 10 can be attached to the attachment base material 20 without blocking the vent hole 22.

  Further, the drain cover 10 that forms the appearance of the vent drain 1 is configured to be detachable from the mounting base 20 and the bracket 30. When the drainage cover 10 is configured to be detachable and replaceable as described above, the drainage cover 10 can be easily replaced with a new one when the drainage cover 10 is damaged due to aging or impact. For this reason, it can be set as the ventilation drainer 1 which is excellent in an external appearance.

  Moreover, the on-off valve 12 is attached to the drain cover 10 so that the exchange is easy.

(Operation of on-off valve 12)
The operation of the on-off valve 12 will be described with reference to FIG. FIG. 5 is a cross-sectional view showing the operation of the on / off valve for venting water, where (a) shows a state where the valve is open and (b) shows a state where the valve is closed.

  As shown in FIG. 5 (a), the on-off valve 12 is open during normal times when the wind is not strong.

  As shown in FIG. 5B, when the wind becomes strong, the valve portion 12a is pushed up by the wind with the hinge portion 12b of the on-off valve 12 as a rotation axis. The pushed-up valve part 12a closes the opening of the ventilation passage W by contacting the valve receiving part 23 of the mounting base 20. Further, in front of the valve receiving portion 23 of the mounting base member 20, there is a stopper 36 of the bracket 30 that protrudes forward and downward. With this configuration, even when the wind becomes stronger, the stopper 36 prevents the valve portion 12a from rising, so that the valve portion 12a does not turn up and enter the ventilation passage W.

  In the conventional configuration where the on / off valve is located at the same position as the vent hole, the pressure is in the direction that the strong wind bounces off the base and opens the on / off valve. May occur. Then, the on-off valve may not close despite the strong wind. In order to solve this, in this embodiment, it was set as the structure which makes it easy to receive a wind by taking out the on-off valve 12 inside the lower end of the water piece 11 to the ventilation passage W side. Thereby, the on-off valve 12 can receive air and can be closed smoothly. Moreover, it is preferable for the convenience of drainage to take the tip of the on-off valve 12 inclining downward.

  Further, as in the present embodiment, the ventilation passage W can be closed at a position where the valve portion 12a and the valve receiving portion 23 are located. For this reason, the position where rainwater enters can be provided at the entrance of the ventilation passage W. Then, since the distance between the vent hole 22 and the entrance of the vent path W can be increased, the possibility that rainwater enters from the vent path W and reaches the vent hole 22 can be reduced. As a result, it is possible to further prevent rainwater from entering the ventilation hole 22.

  The location where the ventilation drainage is installed is a part where the risk of water leakage is extremely high because it may be used on the rooftop. In the present embodiment, technical ideas have been devised, such as draining water by the drain cover 10, stopping water by the on-off valve 12, returning water by the presence of the waterproof layer 7 b, and pouring water by gravity. In the present embodiment, a detail is constructed in which these basic elements of rain performance are united.

  As described above, the drainage cover and the mounting base are configured to be locked and attached via a bracket, so that the assembly is easy, and the manufacture of the drainage cover is not necessarily required because the operation of opening the vent hole is not necessarily required. Become. In addition, since the on-off valve that can close the ventilation passage when wind and rain are strong is configured to be installed on a drainage cover that can be removed, the on-off valve can be easily replaced.

  The present invention can be used for ventilating water drains attached to buildings.
