Description

  The present invention provides water retention or water permeability to the sun as a building exterior material, and vaporizes water from the exterior material surface, thereby cooling the outside air at the exterior material portion and suppressing the heat island phenomenon. The present invention relates to an exterior material having a vaporization cooling function.

  In the city, there are many buildings whose buildings are made of concrete, and these buildings are easily heated by sunlight. For this reason, a large amount of energy is consumed by using cooling in the summer, and a large amount of exhaust heat is generated. As a result, a so-called heat island phenomenon occurs in which the ground temperature in the urban area is higher than that in the peripheral area. Therefore, various measures have been taken to alleviate this heat island phenomenon.

  For example, water is supplied to a member that constitutes an exterior material installed on the outer wall surface of a building and accumulated in the member (water retention), and the accumulated water evaporates when exposed to sunlight. There is known a cooling device that obtains a cooling effect by lowering the ambient temperature by being taken away.

  As such a cooling device, a plurality of blade members made of porous ceramics are continuously provided at a predetermined interval, and a reservoir for temporarily storing water is formed on the upper surface of each blade member so as to form an interior of the blade member. A louver device is known in which water is permeated into water and the surroundings are cooled by utilizing the heat of vaporization (latent heat of vaporization) when the water retained is vaporized when heated by sunlight. (For example, refer to Patent Document 1).

  Alternatively, a plurality of slats formed in an open container shape are attached at intervals in the vertical direction between two pipe-like struts suspended from each other at a predetermined interval. And when plants such as moss are planted inside each slat, water is supplied and drained inside each slat via pipe-like struts, and the water contained in the plant evaporates when heated by sunlight There is known a planting louver device that cools the outer wall of a building with the heat of vaporization and attempts to green the outer wall (see, for example, Patent Document 2).

  Alternatively, the partition wall of the cooling body block, which is made of a porous material and has a ventilation hole penetrating from the front surface to the rear surface, is provided with a water passage through hole penetrating from the upper surface to the lower surface, and grooves on each of the upper, lower, left and right surfaces Are stacked so that the through-holes are staggered in the upper and lower blocks, and a concrete frame having a groove-like water channel and a vertical hole is arranged at the top to wet the entire block with water. And the cooling wall body which acquired the surrounding cooling effect using the heat of vaporization when the water wet when a block is heated with sunlight is vaporized is known (for example, patent documents) 3).

Japanese Patent Laying-Open No. 2006-28927 (FIG. 1, pages 5-6) JP 2002-34347 A (FIGS. 2 and 3) JP 2000-144963 A (FIG. 1, page 3)

  The louver device described in Patent Document 1 requires time and effort for watering in order to store water by watering with a hose or a watering can in a storage part formed by recessing the upper surface of each stage blade member. In addition, during seasons when watering is not required (season when cooling is not required, such as spring, autumn, winter, etc.), dust and dead leaves are likely to accumulate in the reservoir formed on the upper surface of the blade member. Becomes easy to clog. Further, when water is sprayed in the summer when cooling is required, it is necessary to remove these deposits, and maintenance is required. Further, when the pores are clogged, the cooling effect is lowered. Furthermore, stable cooling performance cannot be obtained, for example, the water stored in the storage part formed on the upper surface is scattered by strong wind.

  Moreover, since this louver device is structurally not considered for high-rise buildings, it is difficult to suppress the heat island phenomenon caused by high-rise buildings such as buildings.

  In addition, the paragraph (0029) of Patent Document 1 states that “... In the case where water 19 is supplied while the slat 1 is attached to the support frame 3, with respect to the recess 2 of the top slat 1. By pouring a large amount of water, the overflowing water 19 sequentially flows into the recesses 2 of the lower slats 1 as shown in FIG. In this case, if the wing plate 1 is placed in a horizontal position in advance as shown in Fig. 3 (c), a larger amount of water 19 is utilized using the surface tension. It can be held on 1 ”. However, in a structure in which water overflowing from the upper slats falls to the lower slats, the amount of water supplied is uneven between the upper slats and the lower slats, and sufficient water is supplied to all the slats. It is difficult to infiltrate and retain water.

  Moreover, the planting louver device described in Patent Document 2 has no water retention in the blade plate itself because the blade plate formed in an open container shape is not a porous member such as ceramics. The cooling effect is low because the outside air is cooled by plants such as moss planted. In addition, it is necessary to supply water to the plant inside the slats even in the season when cooling of the outside air is not required, which takes time and effort to manage the plant. Furthermore, when a plant withers, it looks bad and maintenance is not only troublesome but also a sanitary problem occurs.

  Furthermore, since water is supplied to the plurality of blades via the support columns, the amount of supplied water is non-uniform between the upper and lower stages, making it difficult to supply water uniformly to the plants inside each blade. Moreover, this planting louver device is difficult to apply to high-rise buildings because of its structure, and it is difficult to suppress the heat island phenomenon caused by high-rise buildings such as buildings.

  Moreover, since the cooling wall body described in patent document 3 piles up a block and comprises a wall surface, it is difficult to apply to a high-rise building. Further, in paragraph (0027) of Patent Document 3, “Furthermore, in this embodiment, a through hole 32 is provided so as to penetrate one partition wall 14 up and down. The water that has entered the through hole 32 flows along the partition wall 14 and flows out of the through hole 32. This prevents dripping noise and allows water to flow out of the block through the vent hole 12. Is also prevented. "

  However, a structure in which water falls through the partition wall 14 in the block, that is, the through hole 32 constituting the water passage is not a closed water passage such as a pipe, but a part thereof is exposed to the outside air. There is a risk of water leaking or splashing outside. For this reason, when the water which leaked or scattered outside wets the neighborhood or faces the road, there is a possibility that a passerby may be troubled. Moreover, since the blocks are stacked to form the wall surface, there are great restrictions on the design surface.

  In order to prevent such problems caused by the structure of the prior art, it is conceivable that the water channel is a series of closed water channels, but in the case of a simple water channel, water flows from the water channel of the upper block to the block of the lower block. It will only flow into the water channel, and in particular when the water permeability of the block is slow, it becomes difficult to permeate the block with a sufficient amount of water. As a result, it is difficult to obtain a sufficient cooling effect for the block. Further, in order to supply a sufficient amount of water to each block, it is necessary to continuously flow a large amount of water, and water is used wastefully.

  On the other hand, if the water channel is formed by connecting the blocks, the block itself needs to be made of a material having water retention or water permeability, which may result in insufficient strength. When such a block is installed along the outer wall of a relatively high-level building, this insufficient strength is a particular problem.

  An object of the present invention is to provide an exterior material in which a tubular closed channel is constituted by a series of hollow porous bodies and connecting materials, the closed channels themselves have sufficient strength, and water is retained in each porous body. Another object of the present invention is to provide an exterior material having an evaporative cooling function that is excellent in cooling effect and can be suitably applied to a high-rise building by allowing a sufficient amount of water to permeate and hold.

In order to solve the above-described problems, an exterior material having a vaporization cooling function according to the present invention is
A hollow porous body having water retention or water permeability, which is arranged in a row at a predetermined interval in the vertical direction in the installed state, a connecting material for moving water between the upper and lower porous bodies, and a support An exterior material comprising a support for supporting the porous body and the connecting material via a member,
The connecting material is interposed between the upper and lower porous bodies in the installed state of the exterior material, so that a water channel is formed between the porous body and the connecting material,

It can be.

It is sectional drawing corresponding to FIG. 6 explaining the 3rd modification of one Embodiment of this invention.

  Prior to describing a mode for carrying out the present invention, functions and effects of the present invention will be described.

  The exterior material having a vaporization cooling function according to the present invention includes a hollow porous body having water retention or water permeability, which is arranged in a row at a predetermined interval in the vertical direction in the installed state, and between the upper and lower porous bodies. And a support member for supporting the porous body and the connecting material via the support member, and the connecting material is an upper and lower porous body in the installed state of the outer material. A water channel is formed between the porous body and the connecting material, the porous body is tubular, and a connecting material and both ends are connected to the hollow portion of the porous body and a core material that supports the porous body is interposed therebetween. It is inserted, water is passed through the water channel, a part of the water is supplied at least below the porous body, and is vaporized from the surface of the porous body. Accordingly, an appropriate amount of water can be supplied to the porous body while supplementing the strength of the porous body made of a material excellent in water retention or water permeability with the core material, and a cooling effect can be obtained efficiently.

  According to a preferred aspect of the present invention, the core member supports the porous body by contacting the upper surface of the inner periphery of the porous body. Thereby, water can be supplied to the porous body more efficiently while supplementing the strength of the porous body.

  According to a more preferred aspect of the present invention, the core material is a cylindrical body having an outer shape corresponding to the inner peripheral surface of the porous body, and the opening for supplying water to the porous body has at least the core material. It is formed below, and water is passed through the water channel, and a part of the water is supplied to the porous body through the opening of the core material and vaporized from the surface of the porous body. Thereby, it is possible to supply an appropriate amount of water to the porous body while further improving the strength of the porous body with the core material, and to efficiently obtain a cooling effect.

  Further, by supplying a part of the water flowing through the water channel to each porous body through an opening formed at least below the core material, water can penetrate into the entire porous body through the water. . As a result, water can be efficiently retained on the entire surface of the porous body, and the building outer wall and the surrounding outside air can be effectively cooled.

  In addition, when the exterior material is used (during cooling), water can be uniformly infiltrated into all porous bodies just by flowing water through a series of water channels, and when not in use, the water supplied to the water channels is shut off. All you need to do is easy to handle. Furthermore, when using a packaging material that has not been used, first, a large amount of water is supplied to a series of water channels, so that sufficient water can be supplied to all porous bodies in a short time. This makes it possible to increase the cooling effect in a short time. Thereafter, a small amount of water corresponding to the vaporization of the water retained in the porous body may be replenished continuously or intermittently, water saving is possible and water management becomes easy. And since it is not necessary to fill the hollow part of a porous body with water, the load to the exterior material or outer wall by the weight of water can be reduced.

  In addition, by forming the porous body in a tubular shape, it also functions as a sunshade (louver), so that it is possible to more effectively suppress an increase in indoor temperature. Further, the strength can be improved by making the porous body tubular.

  In the exterior material having a vaporization cooling function according to the present invention, it is preferable that the core material and the connecting material for supporting the porous body are joined to the support via the support members.

  In addition, since the core member and the connecting member that support the porous body are each joined to the support via the support member, the workability when attaching to the outer wall of the building is good. Further, when the porous body is clogged or damaged, it is only necessary to replace the porous body, and since the replacement work is easy, the maintainability is excellent. For this reason, it is suitable when many exterior materials are provided on the outer wall of a high-rise building. Moreover, since a series of water channels are formed by the porous body and the connecting material, water is not scattered by strong winds, and adverse effects on the outside are prevented.

  In addition, since the core material and the connecting material that support the porous body are joined to the support via the support members, the core material and the connecting material that support the porous body by the weight of the porous body and the weight of the water flowing inside the porous body. No excessive stress is applied to the connection part. Therefore, local deformation of the packing can be reduced, and leakage of water from the connection portion to the outside can be prevented.

  In the exterior material having a vaporization cooling function according to the present invention, preferably, the porous body is made of ceramics.

  By forming the porous body with ceramics, the degree of freedom of coloring on the surface increases, and it becomes possible to color in various colors according to the appearance of the building. Moreover, various textures on the surface of the porous body, for example, textures having irregularities such as sand walls, textures such as marble, etc. can be freely given, and the aesthetics of the building can be changed. By forming the porous body with ceramics in this way, various designs can be imparted according to the building, so that the aesthetic appearance is excellent. Ceramics are excellent in water retention and water permeability, and can enhance the cooling effect.

  Moreover, in the exterior material which has a vaporization cooling function which concerns on this invention, Preferably, a support | pillar is a hollow body and it is good to connect with the said water channel and a part forms a water supply channel or a drainage channel.

  By connecting a water channel to a column of hollow bodies and making a part a water supply channel or a drainage channel, it becomes possible to form a series of water channels by integrating a plurality of porous water supply channels or drainage channels. It will be more excellent in workability and maintainability.

  Moreover, in the exterior material which has a vaporization cooling function which concerns on this invention, Preferably the connection material and support member which connect porous bodies are covered with the cover member.

  By covering the connecting member and the supporting member that connect the porous bodies with the cover member, the sense of unity between the porous body, the connecting member, and the supporting member is increased, and the appearance of the exterior material is improved. Therefore, by applying the exterior material of the present invention to an old building, the appearance of the building is improved.

  Hereinafter, the exterior material which has a vaporization cooling function concerning one embodiment of the present invention is explained based on a drawing. FIG. 1 is a front view of an exterior material (hereinafter simply referred to as “exterior material”) 1 having an evaporative cooling function according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the porous body 11 of the exterior material 1 shown in FIG. FIG. 3 is an explanatory view when the porous body 11 and the support member 14 of the exterior material 1 shown in FIG. FIG. 4 is a right side view of the packaging material 1 shown in FIG. FIG. 5 is a cross-sectional view along the arrow VV of the exterior material shown in FIG.

  The exterior material 1 which concerns on one Example of this invention has shown the state provided in the outer wall of the 3rd-floor part of the multistory high-rise building which is not shown in figure as shown in FIG. As shown in FIG. 1, the exterior material 1 is formed in a size corresponding to the size of the frontage (left and right width) of the building and the height of the outer wall. Therefore, as shown in the figure, when the frontage of the building is wide and the interval between the pillars 3 and 4 on both sides is wide, the pillar 5 is provided at an intermediate position between the pillars 3 and 4 to limit the length of the porous body 11. The bending due to its own weight and the weight of internal water is reduced to prevent the strength from being lowered.

  The porous body 11 is disposed between the support columns 3 and 5 and the support columns 4 and 5, and one side (right side) end surface of each porous body 11 on the right side in the figure is the right support column 3, and the other side (left side) end surface is Joined to one side (right side) of the central column 5, one side (left side) end surface of each porous body 11 on the left side in the figure is the left column 4, and the other side (right side) end surface is the other side of the central column 5. (Left side) Further, struts 6 and 7 are further arranged at intermediate positions between the central strut 5 and the struts 3 and 4 on both sides, and the flexure of the long porous body 11 is further suppressed and reinforced. As shown in FIG. 5, these pillars 3 to 7 are hollow bodies having a rectangular cross section, and are formed of, for example, a stainless steel member having excellent corrosion resistance and strength.

  And the exterior material 1 is comprised by two cooling parts, the right side cooling part 2R which cools the area | region on the right side from the support | pillar 3 to the support | pillar 5, and the left side cooling part 2L which cools the left side area | region from the support | pillar 5 to the support | pillar 4 Has been. Since the right cooling unit 2R and the left cooling unit 2L are formed symmetrically with respect to the central support column 5, the right cooling unit 2R will be described below.

  The support columns 3 and 4 on both sides are fixed from the top floor to the first floor of the outer wall that defines the rooms on both sides of the building. Moreover, the center support | pillar 5 is set to the predetermined length for every floor, and is being fixed to the outer wall. The columns 3 to 7, particularly the columns 3, 4, and 5 are preferable in terms of increasing the strength if they can be fixed to a column such as a steel frame constituting the framework of the building through the outer wall.

  As shown in FIG. 1, a plurality of porous bodies 11 are arranged in a vertical direction with a predetermined interval, and a plurality of upper stages corresponding to the height of the eyes, for example, the interval from the uppermost stage to the fourth stage is wide. It has a function of sunshade (louver) while avoiding annoyance by ensuring a certain extent of field of view from the room through the window. In addition, the interval between the porous bodies 11 from the fifth stage to the lowest stage, which is lower than the height of the eyes, is set narrow to obtain a sufficient sunshade function.

  The porous body 11 forms a thick hollow body as shown in FIG. 2, and has a long oval cross-sectional shape in the front-rear direction (left-right direction in the figure) of the building. Thus, by making the shape of the porous body 11 into an oblong shape that is long in the front-rear direction, it is possible to have a function of sunshine (louver) more than a simple cylindrical shape. And the hollow part 11a becomes a channel | path (henceforth "water channel") of water. The hollow portion 11a has an oval shape whose cross-sectional shape is long in the front-rear direction, like the outer shape. This porous body 11 is formed of ceramics excellent in water retention and water permeability.

  A core material 12 is accommodated in the hollow portion 11 a of the porous body 11. The core material 12 is set slightly shorter than the porous body 11, and the cross section has a shape corresponding to the inner peripheral surface of the hollow portion 11a, that is, an oval shape similar to that of the hollow portion 11a, and is open on the lower surface over the entire length. It consists of a cylindrical body having a substantially C-shaped cross section in which an opening 12a is formed.

  That is, the core material 12 is a cylindrical body having an outer shape corresponding to the inner peripheral surface of the support member, and the lower opening 12a of the core material 12 is opened over the entire length. That is, the opening 12a for supplying water to the porous body 11 is formed at least below the core material in the installed state of the exterior material. Thus, water is passed through the water channel, and a part of the water is supplied to at least the lower part of the inner peripheral surface of the porous body 11 through the opening 12a of the core member 12, and is vaporized from the surface of the porous body. .

  Engagement claws 12c shaped like scissors are formed at a predetermined position on one side end surface 12b of the core member 12, for example, the upper and lower positions of the front and rear arcs, and are formed by molding. It is bent at right angles to the inside. These engaging claws 12c have a spring property, and have a function of a nut for engaging (screwing) with a connecting bolt 31 described later. Similarly, engaging claws are formed on the other end surface of the core member 12. Note that the engaging claw 12c is not limited to the shape of the hook shown in the figure, and for example, it may be cut and raised in a square shape to provide a screw hole.

  The core material 12 is preferably made of, for example, a stainless steel member having excellent corrosion resistance and strength, and is preferably sized such that the entire outer peripheral surface is in contact with the inner peripheral surface of the hollow portion 11 a of the porous body 11. Thus, by accommodating the core material 12 in the hollow part 11a of the porous body 11, the porous body 11 made of ceramics can be reinforced, and the porous body is particularly resistant to bending when flowing its own weight and water. 11 can be increased. Further, even when the porous body 11 is broken for some reason, it can be prevented from falling, and damage can be minimized.

  In FIG. 2, a slight gap is formed between the inner peripheral surface of the hollow portion 11a of the porous body 11 and the outer peripheral surface of the core member 12, but when the porous body 11 is formed of ceramics, the hollow portion This is because an allowance is provided between the core material 12 and the error of the size of 11a. Thus, even when there is a slight gap between the inner peripheral surface of the hollow portion 11a and the outer peripheral surface of the core member 12, the upper surface of the core member 12 is in the hollow portion 11a in a state where it is joined to the column as described later. This is in contact with and supported by the upper surface of the inner peripheral surface, and there is no particular problem in strength.

  Further, the core material 12 is not limited to the stainless steel member, and other members, for example, a synthetic resin member such as plastic may be used. When a synthetic resin member such as plastic is used, cost can be reduced.

  Next, the joining of the porous body 11 and the column 3 will be described with reference to FIGS. 3 to 5, the column 3 has one end face (right end face) 11b from the uppermost porous body 11 to the third porous body 11 of the right cooling part 2R of the exterior material 1 shown in FIG. Depicts the case of joining.

  One end face (right end face) 11b of the porous body 11 is joined to the support column 3 via the water stop packing 13, the support member 14, and the bracket 15 as shown in FIGS. The water-stop packing 13 has an oval slightly smaller than the cross-sectional shape of the outer shape of the porous body 11, and is provided with water passage holes having the same cross-sectional shape as the hollow portion 11a. As shown in FIG. 5, the support member 14 is substantially L-shaped when viewed from above, and corresponds to the hollow portion 11 a of the porous body 11 and the water passage hole of the water blocking packing 13 on one side of the support portion 14 a. A water passage hole (not shown) is provided at the position, and a connection fitting (joint) 21 for connecting a pipe-shaped connecting member 22 or 23 described later is fixed to the water passage hole. Further, the support portion 14a is provided with bolt insertion holes at positions corresponding to the respective engaging claws 12c of the core member 12. Further, the other side support portion 14b is also provided with a bolt insertion hole.

On the other side of the bracket 15, bolt insertion holes are provided corresponding to the bolt insertion holes of the support portion 14 b of the support member 14. These support members 14 and brackets 15 are also formed of stainless steel members in the same manner as the support columns 3.

  One end surface 11b of the porous body 11 is brought into contact with the support portion 14a of the support member 14 through the water blocking packing 13, and the connection bolt 31 is engaged with the engaging claw 12c of the core member 12 through the bolt insertion hole of the support portion 14a. To be engaged (screwed). As described above, the core material 12 is formed slightly shorter than the porous body 11, so that the water-stopping packing 13 is brought into close contact with the one end face 11 b of the porous body 11 and the support portion 14 a by tightening the bolt 31. These can be connected in a liquid-tight manner. The support portion 14b of the support member 14 is joined to the other side of the bracket 15 by a bolt 32 through a bolt insertion hole. In this way, one end face 11b of the porous body 11 of each stage from the uppermost stage to the lowermost stage is joined to the front side of the support column 3.

  Similarly, the other end face (left end face) of the porous body 11 from the uppermost stage to the lowermost stage is joined to the front right side of the front surface of the column 5 via a water-stopping packing, a support member, and a bracket as shown in FIG. In this way, the porous body 11 at each stage is horizontally joined to the support column 3 and the support column 5.

  The connection fitting 21 of the support member 14 to which the one end face 11b of the uppermost porous body 11 is joined is connected to the lower end portion 22a of the connecting member 22 that is substantially L-shaped and extends upward along the support column 3. ing. The connecting material 22 is formed of a pipe and serves as a water supply channel for the exterior material 1.

  The connection fitting 21 of the support member 14 of the second-stage porous body 11 and the connection fitting 21 of the third-stage porous body 11 are connected by a connecting member 23 as shown in FIGS. The connecting member 23 is also formed of a pipe, has a function of moving water between the hollow portions 11 a of the upper and lower porous bodies 11, and serves as a water channel for the exterior member 1. The connecting member 23 is liquid-tightly connected to the second-stage connection fitting 21 and the third-stage connection fitting 21 by bending the end portions 23a on both sides at right angles to one side. Similarly, one end face 11b of the porous body 11 is connected by a connecting member 23 in the fourth and fifth stages, the sixth and seventh stages, and so on. The connecting member of the supporting member joined to one end face of the lowermost porous body 11 (see FIG. 1) has a substantially inverted L shape and includes a connecting material (not shown) that extends downward along the column 3. The upper end is connected. The connecting material of the lowermost porous body 11 is a drainage channel of the exterior material 1.

Similarly, the other end face of each porous body 11 is connected with a connecting material up to the lowest porous body 11 such as the third and fourth stages, the fifth and sixth stages, and so on. In this way, both end faces are alternately connected from the uppermost porous body 11 to the lowermost porous body 11. Thereby, it connects continuously from the hollow part 11a of the uppermost porous body 11 to the hollow part 11a of the lowermost porous body 11, and forms a series of pipe-shaped water channels.

  As shown in FIGS. 4 and 5, the branch pipe 25 is connected substantially horizontally between the connecting member 23 and a position slightly above the center, for example, between the column 3 and the column 3. One end of the branch pipe 25 is opened to the connecting member 23 and is liquid-tightly joined, and the other end is liquid-tightly inserted into the hole 3 b provided in the front surface 3 a of the support column 3 through the packing 26. It is open. That is, the branch pipe 25 communicates the pipe-shaped connecting member 23 and the hollow support column 3. The branch pipe 25 is used as an air vent and overflow pipe for a water channel including the hollow portion 11a of the porous body 11, the connecting member 23, and the like. And the hollow support | pillar 3 functions as an air vent passage and a drainage passage. The branch pipes 25 may be provided between all the connecting members 23 and the support columns 3 and 5, or a plurality of connecting members 23 may be selected and provided on these connecting members 23.

  On the other hand, a cover member 27 is mounted between both ends of each porous body 11 and the support columns 3 and 4 as shown in FIG. 1, and the water stop packing 13, the support member 14, the connection fitting 21, and the coupling member 23. Is covered. Thereby, the external appearance of the exterior material 1 is improved and the appearance is improved. The cover member 27 is preferably formed of a member made of the same material as that of the porous body 11 so that the sense of unity is increased and the design is preferable. In this way, the right cooling unit 2R shown in FIG. 1 is formed. The left cooling unit 2L is formed symmetrically with the right cooling unit 2R.

  As described above, the exterior material 1 is formed in the size of the outer wall of the first floor of the building, and the exterior material 1 is attached to each floor. 1, 3, and 4, the upper end portion of the connecting member 22 connected to the one end surface 11 b of the uppermost porous body 11 of the exterior member 1 attached to the outer wall of the third floor is the fourth floor ( It is connected to the connection fitting of the supporting member on the one end face of the lowermost porous body of the exterior material (not shown) attached to the outer wall of the upper floor) and connected to the one end face of the lowermost porous body 11 of the outer packaging material 1 The lower end portion of the connecting member (not shown) is connected to the connecting member of the supporting member on the corresponding one side end face of the uppermost porous body of the exterior member (not shown) attached to the outer wall of the second floor (lower floor). In this way, a continuous pipe-like water channel is formed from the top floor exterior material to the first floor exterior material. The left cooling unit 2L is the same as the right cooling unit 2R. The right cooling unit 2R and the left cooling unit 2L have separate cooling systems.

  The water supplied from the connecting member 22 connected to the one side end face 11b of the uppermost porous body 11 of the outer packaging material 1 passes through the hollow portion 11a of the uppermost porous body 11 as shown by a broken line in FIG. Through the connecting material 23, the gas sequentially flows through the hollow portion 11 a of the lower porous body 11 and is discharged from the connecting material connected to the lowermost porous body 11. Therefore, the hollow portion 11a of each porous body 11 forms a water supply channel and a drain channel.

  FIG. 6 is a cutaway view for explaining the operation of the exterior material having the evaporative cooling effect according to the embodiment of the present invention. The water flowing into the hollow portion 11a of each porous body 11 comes into contact with the water in the hollow portion 11a as shown by the arrow in FIG. 6 because the lower opening 12a of the core member 12 is open over the entire length. It penetrates the entire porous body 11 by capillarity from the lower surface and both side surfaces, and is retained on the entire surface.

  Further, the amount of water in the hollow portion 11a of the porous body 11, the amount of water remaining in the lower portion of the connecting member 23 according to the amount of water in the hollow portion 11a, the air in the hollow portion 11a, the air in the connecting member 23, etc. Depending on the pressure of the air in the material 23, a phenomenon may occur that a water plug (portion where water stays) is formed in the middle of the connecting material 23 and is blocked and the water does not flow. In order to prevent such a phenomenon, the air in the connecting member 23 is released into the hollow support column 3 through the branch pipe 25 and the connecting member 23 is prevented from being blocked by a water stopper.

  Further, when the water is passed through the water channel of the exterior material 1 for a long time or when a large amount of water is supplied at a time, the connecting material 23 may be clogged with water due to overflow (overflow). In such a case, a part of the water in the connecting member 23 (the overflowed portion) is discharged into the hollow column 3 through the branch pipe 25 and discharged to the outside of the exterior member 1. Accordingly, it is possible to stably flow a necessary amount of water into the water channel of the exterior material 1 and to detect a problem that the water channel is blocked by detecting the water discharged from the lower end of the support column 3. Also useful.

  In addition, the exterior material 1 is provided with the connection material 22 of the uppermost porous body 11 as a water supply channel, and the connection material connected to one end face of the lowermost porous body as a drainage channel and extending downward. However, it is also possible to use the hollow column 3 as a water supply channel or a drainage channel.

  The water retained on the entire surface of the porous body 11 is vaporized when heated by solar heat, and the ambient temperature is lowered and cooled by the heat of vaporization at this time. Moreover, the porous body 11 has a function of sunshade because it has an oblong shape that is long in the front-rear direction, and effectively blocks direct sunlight. Thereby, the temperature of the outer wall of a building can be lowered, the heat island phenomenon can be suppressed, and the indoor temperature can be lowered.

  Further, when the exterior material 1 is used (cooled), it is possible to infiltrate all porous bodies 11 through the openings of the core material and to keep the water by simply flowing water through a series of water channels. When used, it is only necessary to shut off the water supplied to the water channel, and the handling becomes easy. Further, when using the exterior material 1 that has been in a non-use state, by supplying a large amount of water first, it becomes possible to sufficiently supply water to all the porous bodies 11 in a short time and to retain the water. The cooling effect can be increased over time. Then, a small amount of water corresponding to the vaporization of the water retained in the porous body 11 may be replenished continuously or intermittently, water saving is possible and water management is easy.

  Further, the amount of water supplied to the exterior material 1 can be adjusted according to the weather condition. For example, it is possible to use water effectively by flowing water intermittently, flowing a small amount, or temporarily storing water so as to be immersed. Therefore, the exterior material 1 is also effective for ecological measures, cool biz measures, and energy saving measures. Further, since a series of water channels is formed by the inside of the porous body 11 and the connecting material 23, water is not scattered by strong winds, and adverse effects to the outside are prevented.

  As described above, according to the exterior material having a vaporization cooling function according to the present invention, the core material is a cylindrical body having an outer shape corresponding to the inner peripheral surface of the porous body, and supplies water to the porous body. An opening is formed at least below the core material, water is passed through the water channel, a part of the water is supplied to the porous body through the opening of the core material, and is vaporized from the surface of the porous body. . Accordingly, an appropriate amount of water can be supplied to the porous body while supplementing the strength of the porous body made of a material excellent in water retention or water permeability with the core material, and a cooling effect can be obtained efficiently.

  Further, by supplying a part of the water flowing through the water channel to each porous body through an opening formed at least below the core material, water can penetrate into the entire porous body through the water. . As a result, water can be efficiently retained on the entire surface of the porous body, and the building outer wall and the surrounding outside air can be effectively cooled.

  In addition, when the exterior material is used (during cooling), water can be uniformly infiltrated into all porous bodies just by flowing water through a series of water channels, and when not in use, the water supplied to the water channels is shut off. All you need to do is easy to handle. Furthermore, when using a packaging material that has not been used, first, a large amount of water is supplied to a series of water channels, so that sufficient water can be supplied to all porous bodies in a short time. This makes it possible to increase the cooling effect in a short time. Thereafter, a small amount of water corresponding to the vaporization of the water retained in the porous body may be replenished continuously or intermittently, water saving is possible and water management becomes easy. And since it is not necessary to fill the hollow part of a porous body with water, the load to the exterior material or outer wall by the weight of water can be reduced.

  In addition, by forming the porous body in a tubular shape, it also functions as a sunshade (louver), so that it is possible to more effectively suppress an increase in indoor temperature. Further, the strength can be improved by making the porous body tubular.

  In addition, by forming the porous body in a tubular shape, it also functions as a sunshade (louver), so that it is possible to more effectively suppress an increase in indoor temperature. Further, the strength can be improved by making the porous body tubular.

  Further, by forming the porous body with ceramics, the degree of freedom of coloring of the surface is increased, and it is possible to color in various colors according to the appearance of the building. Furthermore, various textures on the surface of the porous body, for example, textures having irregularities such as sand walls, textures such as marble, etc. can be freely produced, and the appearance of the building can be changed. By forming the porous body with ceramics in this way, various designs can be imparted according to the building, so that the design is excellent. Moreover, ceramics are excellent in water retention and water permeability and can enhance the cooling effect.

  In addition, when a plurality of porous water supply / drainage channels are integrated to form a series of water channels, the workability and maintainability are further improved.

  Further, since the connecting members 22 and 23 that connect the porous bodies to each other and the support member 14 are covered with the cover member 27, a sense of unity between the porous body 11, the connecting materials 22 and 23, and the support member self member 14 is increased. The appearance of the exterior material 1 is improved. Therefore, the exterior of the building is improved by applying the exterior material 1 to the old building. Moreover, the exterior material 1 becomes a blindfold and sunshade.

A core material 212 made of a body may be used. In this case, the water in the water channel can be supplied to the porous body 11 from any of the large number of openings 212a made of the burring holes while the strength of the core material is further increased by the cut and raised portions of the respective burring holes, and the water flows into the water channels. The responsiveness until the cooling of the exterior material after it is further increased.

  Furthermore, as shown in the third modified example of FIG. 9, a core material 312 made of a tubular body made by twisting and welding a wire made of a thick steel material having sufficient strength into a mesh shape may be used. good. In this case, the gap between the wires becomes the opening 312a, and water in the water channel can be uniformly supplied from the opening 312a to the inner peripheral wall of the hollow portion of the porous body 11, and the exterior material after flowing water through the water channel To further improve the response to cooling.
