Description

  The present invention relates to a partition structure for forming a comfortable living environment in a building.

In recent years, from the viewpoint of energy saving and global warming countermeasures, we want to create a comfortable living environment in the building by opening the windows and doors of each room of the building and performing natural ventilation without using air conditioning equipment and ventilation equipment. There is a request. However, in summer, the outside air introduced into the building is warm, and in urban areas, the temperature rises due to the heat island phenomenon, so it may be difficult to obtain the effect of natural ventilation.
Therefore, for example, as described in Patent Document 1, a porous material layer having water absorption is provided on the surface as a building material constituting an external structure (partition structure) such as a fence, a gate, a fence, a handrail, and a louver. Is used.
According to the building material in Patent Document 1 and the exterior structure using the same, when water is included in the porous material layer on the surface of the building material, the surface of the exterior structure and the surrounding air are removed by the heat of vaporization of the water. Can be cooled. A comfortable living environment can be formed even in summer by introducing the cooled air into the building.

Next, the flow of water in the partition structure 10 will be described.
First, water is supplied from a water supply source (not shown), and the water reaches the upper end portion of the partition structure 10 through the water supply pipe 17. The water that has reached the upper end portion of the partition structure 10 passes through the water supply holes and falls to the water storage portion 12b in the first surface portion 12 of the building material 11 located at the uppermost position among the plurality of building materials 11.

When the water that has fallen into the water storage section 12b exceeds the allowable water storage capacity, it reaches the second surface sections 13 on both sides through the water flow section 12c.
The water that has reached the second surface portion 13 is transmitted in the extending direction of the transverse flow path portion 13a by the surface tension, and reaches the both ends of the second surface portion 13 in the length direction. And the water exceeding the allowable amount that can be held by the surface tension flows downward, and falls downward from the corner of the lower end of the building material 11.

Water that falls downward from the corner of the lower end of the building material 11 is received by the water storage part 12b in the second building material 11 from the top, and if the water storage allowable amount of the water storage part 12b is exceeded, it passes through the water flow part 12c. It reaches the second surface portion 13 on both sides.
By repeating the process as described above, water falls downward from the corner of the lower end of the building material 11 located at the lowest position. Thereby, it will be in the state where water was transmitted to the whole surface of the some building material 11. FIG.
In addition, the drainage | grounding means which receives and drains the water which fell from the building material 11 located in the lowest may be provided in the ground or the floor surface.

And the wide range of the some building materials 11 can be cooled using the vaporization heat of the water transmitted to the whole surface of the some building materials 11, and the air around the partition structure 10 is cooled in connection with this. Demonstrate the effect.
When natural ventilation is performed in the building, the outside air cooled from the outdoor side space toward the building side space is sent through the ventilation portion 14, and the cooled outside air is introduced into the building from the opening of the building. As described above, natural ventilation in the building can be performed.
Note that it is preferable that the opening of the building and the partition structure 10 face each other because the cooled outside air can be easily taken into the building.

  According to the present embodiment, since the first surface portion 12 has the water passage portion 12c that transmits water toward the second surface portion 13, the water passes from the first surface portion 12 through the water passage portion 12c to the second surface portion 12c. It is reliably transmitted toward the surface portion 13. Moreover, since the 2nd surface part 13 has the some horizontal flow-path part 13a extended in the horizontal direction and arranged in parallel up and down, water is the width direction of the 2nd surface part 13 through these several horizontal flow-path parts 13a. Will be transmitted in a wide range. Therefore, the wide range of the building material 11 can be cooled using the heat of vaporization of water, and the effect of cooling the air around the partition structure 10 can be exhibited. Therefore, when natural ventilation is performed in the building, the outside air cooled from the outdoor side space toward the building side space can be sent through the ventilation portion 14, and the cooled outside air can be introduced into the building. And even if it does not provide special layers, such as the adhesive layer which has hydrophobicity, and the porous material layer which has water absorption conventionally, on the surface of a base material, the water flow part 12c and several crossflows on the surface of the building material 11 Since it is possible to introduce the cooled outside air into the building simply by providing the path portion 13a, it is possible to reliably reduce the cost of materials and manufacturing.

  Moreover, if the 2nd surface part 13 has the several vertical flow path part 13b formed crossing the several horizontal flow path part 13a, the width direction of the 2nd surface part 13 will pass through several horizontal flow path parts 13a. Water transmitted in a wide range is also transmitted in the vertical direction of the second surface portion 13 through the plurality of vertical flow path portions 13b. Thereby, water transmitted from the first surface portion 12 can be transmitted to a wider range of the second surface portion 13, so that it is possible to easily generate heat of vaporization of water.

  In addition, although the horizontal flow path part 13a and the vertical flow path part 13b in this embodiment are formed as a groove | channel, it is not restricted to this, For example, the protrusion which a water flows along may be sufficient, It may be a flat passage located between adjacent openings. That is, it is only necessary to secure a passage (flow path) through which water flows.

The water reaching the second surface portion 23 is transmitted in the extending direction of the lateral flow passage portion 23a by the capillary force (surface tension), and the water exceeding the allowable amount that can be held by the surface tension flows downward. It falls downward from the lower end, or falls downward after reaching the lower surface of the building material 21.

The water that has fallen downward from the upper building material 21 is received by the first surface portion 22 of the second building material 21 from the top, and reaches the second surface portion 23 through the water passage portions 22c that are a plurality of grooves.
By repeating the process as described above, water falls downward from the lowermost building material 21, and thus the water is transmitted to the entire surface of the plurality of building materials 21, so that the first embodiment and Similarly, a state suitable for natural ventilation in a building can be formed around the partition structure 20.

According to this embodiment, similarly to the first embodiment, it is possible to cool a wide range of the building material 21 using the heat of vaporization of water, and accordingly cool the air around the partition structure 20. The effect can be demonstrated. As a result, it is possible to reliably reduce the cost of materials and manufacturing without providing special layers such as a hydrophobic adhesive layer or a water-absorbing porous material layer on the surface of the substrate as in the past. Can do.
Further, if the second surface portion 23 has a plurality of vertical flow path portions formed so as to intersect with the plurality of horizontal flow path portions 23 a, the water transmitted from the first surface portion 22 is transferred from the second surface portion 23. Since it can be transmitted to a wide range, the heat of vaporization of water can be easily generated.

  Furthermore, when a hydrophilic film (coating film) such as a photocatalyst is provided on the surface of the building material 21, grooves (water passage portions 22 c, lateral flow path portions) formed on each surface of the building material 21. 23a, which is synergistic with the function of the capillary force of the longitudinal flow path portion), which is preferable because water can be spread quickly in the horizontal direction. Moreover, since such a film (coating film) is provided auxiliary, it is possible to reduce the amount of material forming the film and simplify the coating process.

In the present embodiment, the building material 21 has a rectangular parallelepiped shape. However, the present invention is not limited to this, and as shown in FIG. 6, the building material 21 is formed in a substantially rectangular parallelepiped shape with chamfered corners or rounded corners. It may be formed in a substantially rectangular parallelepiped shape with (R: R).
6A is a cross-sectional view in the case where all corners of the building material 21 (building material 21A) are rounded, and FIG. 6B has bulges on the upper and lower surfaces of the building material 21 (building material 21B). FIG. 6C is a cross-sectional view when all corners are rounded, and FIG. 6C is a cross-sectional view that is rounded or elliptical with all corners of the building material 21 (building material 21C) rounded. It is sectional drawing in the case of being formed.
In this way, by making all the corners of the building material 21 not to be bent more angularly than right angles, a phenomenon called “wetting pinning effect” can be reduced. That is, the water is prevented from accumulating without passing through the right-angled corners, so that the water is easily transmitted from the first surface portion 22 to the second surface portion 23.
Further, in the case of the shapes as shown in FIGS. 6B and 6C, the water transmitted to the lower surface of the building material 21 is likely to gather in the center, and there is an advantage that the water easily falls downward.
In addition, the shape shown in FIG. 6 may be appropriately employed at any corner of the building material 21 shown in FIG.

The water flow portion 32c is a vertical and horizontal cross-shaped groove formed in the first surface portion 32, and its end portion is open toward the side, and the second surface portion 33 is a four side surface. It plays the role of supplying water to each.

The second surface portion 33 is located below the first surface portion 32, is continuous with the first surface portion 32, and is disposed at an angle different from the first surface portion 32. That is, since the building material 31 is formed in a rectangular parallelepiped shape as described above, the second surface portion 33 is disposed perpendicular to the first surface portion 32.
In addition, on the surface of the second surface portion 33, a plurality of horizontal flow path portions 33a that are grooves arranged in parallel in the vertical direction along the circumferential direction of the building material 31 itself are formed.

In order to enhance the effect of such capillary force, a hydrophilic film such as a photocatalyst (coating film) may be provided on the surface of the building material 31 as an auxiliary.

The support part 35 is two elongate connection members which connect the upper end parts and the lower end parts of the plurality of building materials 31, respectively. These two support portions 35 are attached to the outer wall surface of the building.
Above the plurality of building materials 31, there is a water supply pipe (not shown) so that water can be supplied to the first surface portion 32 of each building material 31.

  The main surface of the partition structure 30 configured as described above refers to a front side region and a back side region of the partition structure 30 including a plurality of building materials 31 and a ventilation portion 34.

The water supplied from the water supply pipe falls to the first surface portions 32 of the plurality of building materials 31.
The water that has fallen on the first surface portion 32 reaches the second surface portion 33 through a water passage portion 32c that is a cross-shaped groove by capillary force (surface tension). The water reaching the second surface portion 33 is transmitted in the extending direction of the lateral flow passage portion 33a by capillary force (surface tension), and the water exceeding the allowable amount that can be held by the surface tension flows downward. It falls downward from the lower end, or falls downward after reaching the lower surface of the building material 31.

Moreover, if the 2nd surface part 33 has the several vertical flow path part formed crossing the several horizontal flow path part 33a, it can make it easy to generate the vaporization heat of water.
Furthermore, according to the present embodiment, since the plurality of building materials 31 function as vertical lattice members, the water supplied from the upper water supply pipe flows from the upper end portion of each building material 31 to the lower end portion, It is easy to spread water over the entire partition structure 30.

Next, a fourth embodiment of the present invention will be described with reference to the drawings. For convenience of explanation, only components that are different from the first to third embodiments described above will be described.

  As shown in FIGS. 8 to 10, the partition structure 40 in the present embodiment includes a building material 41 that constitutes a main surface for dividing an outdoor space into a building-side space and an outdoor-side space, and a building divided by the main surface. The ventilation part 44 which connects a side space and outdoor side space, and the support part (not shown) which supports the building material 41 are provided.

The building material 41 is a molded product formed in a plate shape, and receives a water from above and flows downward, a second surface portion 43 that causes water transmitted from the first surface 42 to flow downward, Is provided.
More specifically, the building material 41 includes a plurality of first surface portions 42 formed in a plate shape and a plurality of second surface portions 43 formed in a plate shape alternately arranged in the vertical direction. It is configured by being arranged in a zigzag manner. Each of the plurality of first surface portions 42 and the plurality of second surface portions 43 formed in a plate shape is disposed so as to be inclined with respect to the vertical direction. Therefore, each 1st surface part 42 and each 2nd surface part 43 will be in the state provided with the upper surface (surface diagonally upward) and the lower surface (surface diagonally downward) inclined with respect to a perpendicular direction.

The first surface portion 42 extends in the horizontal direction and is arranged in parallel up and down, and a plurality of vertical flow passage portions 42b formed so as to intersect the plurality of horizontal flow passage portions 42a. And a water passage portion 42 c that transmits water toward the second surface portion 43.

That is, the 1st surface part 42 and the 2nd surface part 43 have the same component, and the direction of the front-back direction is just reverse. Further, the first surface portion 42 and the second surface portion 43 are integrally formed or integrally formed.

The ventilation portion 44 is configured mainly with a plurality of through holes (through holes 44a) formed in the first surface portion 42 and the second surface portion 43, respectively. The plurality of horizontal flow path portions 42 a and 43 a and the plurality of vertical flow path portions 42 b and 43 b are arranged avoiding the plurality of ventilation portions 44.
The plurality of ventilation portions 44 are regularly arranged with respect to the plate-like first surface portion 42 and the second surface portion 43. In other words, the plurality of ventilation portions 44 are formed in the first surface portion 42 and the second surface portion 43 by, for example, a punching technique (metal mesh manufacturing technique) for a metal plate such as a punching metal or an expanded metal. The horizontal flow path portions 42 a and 43 a and the plurality of vertical flow path portions 42 b and 43 b are arranged corresponding to the positions of the plurality of ventilation portions 44. In addition, the ventilation portions 44 arranged vertically are shifted in the horizontal direction and are in a so-called “staggered arrangement” state.

As shown in FIG. 10, each ventilation part 44 includes a through hole 44a that should be called a main body of the ventilation part 44, and a cover part 44b that covers the through hole 44a in a bowl shape.
The through hole 44a is formed so as to penetrate each of the plurality of first surface portions 42 and the plurality of second surface portions 43 formed in a plate shape in the thickness direction.
The cover part 44b is in a state of covering the through hole 44a, and the through hole 44a is in a state of opening downward by the cover part 44b. Accordingly, it is possible to prevent water flowing from the top to the bottom from flowing into the through hole 44a.

  In addition, if the surface with the cover part 44b which comprises the ventilation | gas_flowing part 44 is a "front part" in the 1st surface part 42 and the 2nd surface part 43, the front part of the 1st surface part 42 and the front part of the 2nd surface part 43 will be As shown in FIG. 9, it is in a state of being directed in the opposite direction. That is, the front part of the first surface part 42 is directed to the front side of FIG. 9, and the front part of the second surface part 43 is directed to the back side of FIG.

The water flow portions 42 c and 43 c are a plurality of through holes formed through the lower ends of the first surface portion 42 and the second surface portion 43, and are arranged side by side with the plurality of ventilation portions 44.
More specifically, the water passing portions 42 c and 43 c in the first surface portion 42 and the second surface portion 43 are formed in the same manner as the through holes 44 a in the plurality of ventilation portions 44 described above, and together with the plurality of ventilation portions 44. It is in a staggered arrangement. That is, the water flow portions 42c and 43c, which are through holes, have the same configuration as the state in which the cover portions 44b of the plurality of ventilation portions 44 are not provided.
Since the water passing portions 42c and 43c do not have a bowl-shaped cover portion as described above, water flows in. Therefore, water moves from the upper surface inclined with respect to the vertical direction of each first surface portion 42 and each second surface portion 43 toward the lower surface inclined with respect to the vertical direction through the water flow portions 42c and 43c. Will do.

The support portion (not shown) is two support columns configured in the same manner as in the first embodiment described above, and a water supply pipe cover 46 is provided between the upper end portions. A water supply pipe 47 is passed through the hollow portion of the water supply pipe cover 46. The water supply pipe cover 46 has a plurality of water supply holes 46a.

  A plurality of building materials 41 as described above are used, and the plurality of building materials 41 are arranged side by side so as to be adjacent to each other in the lateral direction. In such a case, the width dimension of each building material 41 is set to a short width dimension as shown in FIG. 8, for example. However, the present invention is not limited to this, and the width dimension of the building material 41 can be appropriately changed without departing from the gist of the present invention, and the partition structure 40 is configured by using the building material 41 having a long width dimension alone. You may make it do.

The main surface of the partition structure 40 configured as described above refers to the front-side region and the back-side region of the partition structure 10 including a plurality of building materials 41 arranged side by side and the ventilation portion 44.
That is, although the first surface portion 42 and the second surface portion 43 are provided in reverse, the front side region that is visible when the partition structure 40 is viewed as a whole and the opposite back side region are the main surfaces. It is said that.

Next, the flow of water in the partition structure 40 will be described.
First, water is supplied from a water supply source (not shown), and the water reaches the upper end portion of the partition structure 40 through the water supply pipe 47. The water that has reached the upper end portion of the partition structure 40 passes through the water supply hole and falls to the upper surface of the first surface portion 42 that is located at the uppermost position and that is inclined with respect to the vertical direction.

The water that has fallen to the upper surface of the first surface portion 42 that is inclined with respect to the vertical direction spreads over the entire upper surface of the first surface portion 42 while flowing downward through the horizontal flow channel portion 42a and the vertical flow channel portion 42b.
The water that has reached the lower end of the first surface portion 42 flows to the lower surface of the first surface portion 42 that is inclined with respect to the vertical direction through the water passage portion 42c. Then, it flows further downward and reaches the upper end portion of the upper surface of the second surface portion 43 that is inclined with respect to the vertical direction.

The water that has reached the upper end portion of the upper surface of the second surface portion 43 that is inclined with respect to the vertical direction spreads over the entire upper surface of the second surface portion 43 while flowing downward through the horizontal flow channel portion 43a and the vertical flow channel portion 43b.
The water that has reached the lower end portion of the second surface portion 43 flows to the lower surface of the second surface portion 43 that is inclined with respect to the vertical direction through the water flow portion 43c. And it flows further down and reaches the upper end part of the upper surface which inclines with respect to the perpendicular direction of the 1st surface part 42 located below.

  By repeating the above-described process, water falls downward from the lower end portion of the first surface portion 42 or the second surface portion 43 located at the lowest position. As a result, since water is transmitted to the entire surface of the building material 41, a state suitable for natural ventilation in the building is formed around the partition structure 40 as in the first to third embodiments. can do.

  According to the present embodiment, the plurality of first surface portions 42 and the plurality of second surface portions 43 having the same configuration are arranged alternately in the vertical direction and arranged in a zigzag manner. Therefore, water can be alternately transmitted to the plurality of first surface portions 42 and the plurality of second surface portions 43 arranged in parallel in the vertical direction through the water flow portions 42 c and 43 c. As a result, it is possible to introduce the cooled outside air into the building without providing a special layer such as a hydrophobic adhesive layer or a water-absorbing porous material layer on the surface of the substrate as in the past. Costs for materials and manufacturing can be reliably reduced. Moreover, it is possible to easily generate heat of vaporization of water by the plurality of vertical flow path portions 42b and 43b.

  In addition, each of the first surface portion 42 and the second surface portion 43 includes a plurality of vertical flow path portions 42b and 43b formed so as to intersect with the plurality of horizontal flow path portions 42a and 43a. , 43a, the water transmitted in a wide range in the width direction of the first surface portion 42 and the second surface portion 43 also in the vertical direction of the first surface portion 42 and the second surface portion 43 through the plurality of longitudinal flow path portions 42b, 43b. It will be transmitted. As a result, water that is alternately transmitted between the plurality of first surface portions 42 and the plurality of second surface portions 43 can be transmitted to a wider range of the first surface portion 42 and the second surface portion 43. It is possible to easily generate heat of vaporization.

  Further, the plurality of horizontal flow path portions 42a and 43a and the plurality of vertical flow path portions 42b and 43b avoid the plurality of through holes (through holes 44a) formed in the first surface portion 42 and the second surface portion 43, respectively. Since they are arranged, a path through which water is transmitted and a path through which air passes can be secured in each of the first surface portion 42 and the second surface portion 43.

  In addition, since the partition structure body 40 in this embodiment is provided with a plurality of building materials 41 arranged side by side, air can be passed through the gaps between the plurality of building materials 41. As a result, for example, the amount of air that escapes from the one side space of the partition structure 40 to the other side space increases rather than when the building material 41 is used alone, so that when introducing the cooled outside air into the building Is preferred.

A ventilation portion 54 that communicates with the outdoor space and a support portion 55 that supports the building material 51 are provided.

The building material 51 is a molded product formed in a plate shape, a first surface portion 52 that receives water from above and flows downward, a second surface portion 53 that flows downwardly the water transmitted from the first surface portion 52, and A fixing portion 58.
More specifically, the building material 51 includes a plurality of first surface portions 52 formed in a plate shape and a plurality of second surface portions 53 formed in a plate shape alternately arranged in the vertical direction. It is configured by being arranged in a zigzag manner. Further, each of the plurality of first surface portions 52 and the plurality of second surface portions 53 formed in a plate shape is disposed so as to be inclined with respect to the vertical direction. Therefore, each 1st surface part 52 and each 2nd surface part 53 will be in the state provided with the upper surface (surface diagonally upward) and the lower surface (surface diagonally downward) inclined with respect to a perpendicular direction.
The first surface portion 52 is set to have a gentle inclination, and the second surface portion 53 is set to have a steep inclination.

The first surface portion 52 extends in the horizontal direction and crosses the plurality of horizontal flow path portions (located between adjacent cover portions 54b and 54b) arranged in parallel in the vertical direction and the plurality of horizontal flow path portions. A plurality of longitudinal flow path portions formed, and a water flow portion 52 c that transmits water toward the second surface portion 53.

In addition, the fixing | fixed part 58 may be provided in the upper end part of the 1st surface part 52 located in the uppermost part.

The ventilation portion 54 is configured mainly with a plurality of through holes (through holes 54a and 54c) formed in the first surface portion 52 and the second surface portion 53, respectively. The plurality of horizontal flow path portions and the plurality of vertical flow path portions are arranged avoiding the plurality of ventilation portions 54.
The plurality of ventilation portions 54 are regularly arranged with respect to the plate-like first surface portion 52 and the second surface portion 53. That is, the plurality of ventilation portions 54 are formed on the first surface portion 52 and the second surface portion 53 by a punching technique (metal mesh manufacturing technique) of a metal plate such as a punching metal or an expand, for example. The horizontal flow path portion and the plurality of vertical flow path portions are arranged corresponding to the positions of the plurality of ventilation portions 54.

The ventilation portions 54 formed on the first surface portion 52 are arranged in a so-called “staggered arrangement” in which the ventilation portions 54 arranged vertically are shifted from each other in the horizontal direction.
The ventilation portion 54 in the first surface portion 52 includes a plurality of through holes 54a as a main body and a plurality of cover portions 54b that cover the plurality of through holes 54a in a bowl shape. The cover part 54b is in a state of covering the through hole 54a, and the through hole 54a is in a state of opening downward by the cover part 54b.

The ventilation part 54 formed in the second surface part 53 does not include a cover part, and is configured by a plurality of through holes 54c. The through hole 54 c is a slit-like long hole formed in a long shape along the width direction (lateral direction) of the second surface portion 53. The through hole 54 c of the second surface portion 53 is formed longer in the lateral direction than the through hole 54 a of the first surface portion 52.
The plurality of through holes 54c may be formed to have a length corresponding to the length in the width direction of the second surface portion 53 and arranged side by side vertically, or may be formed shorter than this and staggered. Good.

The water flow portions 52 c and 53 c are a plurality of through holes formed through the lower ends of the first surface portion 52 and the second surface portion 53, and are arranged side by side with the plurality of ventilation portions 54.
The water passing portions 52c and 53c have no cover portion, so that water easily flows in. Thereby, water passes from the upper surface inclined with respect to the vertical direction of each first surface portion 52 and each second surface portion 53 to the lower surface inclined with respect to the vertical direction through the water flow portions 52c and 53c. Will move.

The support part 55 is two support | pillars comprised similarly to 1st Embodiment mentioned above, and the water supply pipe cover 56 is spanned and provided between upper end parts. A water supply pipe 57 is passed through the hollow portion of the water supply pipe cover 56. The water supply pipe cover 56 has a plurality of water supply holes 56a.
A fixing portion 58 of the building material 51 is fixed to the side surface of the support portion 55. In addition, the uppermost first surface portion 52 of the building material 51 is disposed below the water supply hole 56a, and water that has dropped from the water supply hole 56a can be received by the uppermost first surface portion 52.

  Note that a plurality of building materials 51 are used in the same manner as in the above-described fourth embodiment, and the plurality of building materials 51 are arranged side by side so as to be adjacent in the horizontal direction. Moreover, the width dimension of the building material 51 can be changed as appropriate without departing from the spirit of the present invention, and the partition structure 50 may be configured by using the building material 51 having a long width dimension alone.

Next, the flow of water in the partition structure 50 will be described.
First, water is supplied from a water supply source (not shown), and the water reaches the upper end portion of the partition structure 50 through the water supply pipe 57. The water that has reached the upper end portion of the partition structure 50 passes through the water supply hole 56a and falls to the upper surface of the first surface portion 52 that is located at the uppermost position that is inclined with respect to the vertical direction.

The water that has fallen to the upper surface of the first surface portion 52 that is inclined with respect to the vertical direction spreads over the entire upper surface of the first surface portion 52 while flowing downward through the horizontal flow channel portion and the vertical flow channel portion.
The water that has reached the lower end of the first surface portion 52 flows to the lower surface of the first surface portion 52 that is inclined with respect to the vertical direction through the water flow portion 52c. Then, it flows further downward and reaches the upper end portion of the upper surface of the second surface portion 53 that is inclined with respect to the vertical direction.

The water that has reached the upper end of the upper surface of the second surface portion 53 that is inclined with respect to the vertical direction spreads over the entire upper surface of the second surface portion 53 while flowing downward through the horizontal flow channel portion and the vertical flow channel portion.
The water that has reached the lower end portion of the second surface portion 53 flows downward through the water flow portion 53c, passes through the fixing portion 58, and the upper surface of the first surface portion 52 that is positioned below is inclined with respect to the vertical direction. The top end will be reached.

  By repeating the process as described above, water falls downward from the lower end portion of the first surface portion 52 or the second surface portion 53 located at the lowest position. As a result, since water is transmitted to the entire surface of the building material 51, a state suitable for natural ventilation in the building is formed around the partition structure 50 as in the first to fourth embodiments. can do.

According to the present embodiment, not only the same effects as in the fourth embodiment described above can be obtained, but also the first surface portion 52 and the second surface portion 53 can have different functions.
That is, the first surface portion 52 is gently inclined at an angle close to a direction orthogonal to the vertical direction. For this reason, the water spreads in the width direction of the first surface portion 52 until it reaches the lower end portion of the first surface portion 52, so that it is easy to spread the water over a wide range.
Moreover, since the through-hole 54c is a slit-like long hole and does not include a cover, the second surface portion 53 can increase the aperture ratio compared to the first surface portion 52. This increases the amount of air that escapes from the one side space of the building material 51 to the other side space, which is suitable for introducing cooled outside air into the building. In addition, since the aperture ratio is high in this way, water flows while the water droplets gradually fall downward from the through-hole 54c, so that even when the water droplets fall midway, the first surface portion 52 located below is in a wide range. Water can be supplied. Furthermore, since a certain amount of line-of-sight can be secured, it is suitable for functioning as a fence.
