[0021] [1. Mode 1 of the heat insulation panel according to an embodiment of the present invention] [Regarding the structure] First, the structure of the heat shielding panel 1 according to one embodiment of the present invention (hereinafter, First Embodiment The following will be described using Figure 1. As shown in Figure 1, the present invention first The heat shield panel 1 according to this embodiment has a structure in which a single metal plate is bent at four bending points 2.

[0022] These four bends divide the heat shield panel 1 into the following areas, from left to right in Figure 1: the first connection section 3, the upper ventilation section 4, the main body section 5, the lower ventilation section 6, and the second connection section 7.

[0023] next Heat shielding panel 1 Let's describe each part. First, the first connection part 3 is the part that is fixedly connected to the upper flat surface of a protrusion such as a corrugated metal roof via connecting members such as bolts and nuts. Since this part has such a connection function, if there is an area large enough to be fixed, the size of that area ( figure In 1 Heat-shielding panel 1 (Width from left to right) teeth, Any length is acceptable as long as it can be fixed to the corrugated metal roof.

[0024] Next, the upper ventilation section 4 will be described. When the heat shield panel 1 according to one embodiment of the present invention is installed on a corrugated metal roof 20, the upper ventilation section 4 of the heat shield panel 1 is positioned at an inclination (for example, at approximately 60° with respect to the horizontal plane). do Therefore, the wind from above passes through the ventilation opening 8 of the upper ventilation section 4, and the air below the heat shield panel between the corrugated roof and the heat shield panel in between Wind flows in.

[0025] The upper ventilation section 4 is provided with ventilation openings 8 for ventilation, but the shape of these ventilation openings 8 is not limited to any particular type. That is, it may consist of multiple circular holes arranged regularly, or it may be a single large rectangular opening, etc.

[0026] Next, we will describe the main body 5. As shown in Figure 1, the main body 5 is a roughly rectangular plate-like structure. When the heat shield panel 1 is installed on the corrugated metal roof 20, the main body 5 is... The surface of the board The configuration is inclined at approximately 30° with respect to the horizontal plane. In other words, as shown in Figure 3, the main body 5 is installed with a left-to-right inclination, with the side where the upper ventilation section 4 is connected being the upper part and the side where the lower ventilation section 6 is connected being the lower part.

[0027] In this case, the main body 5 has the functions of reflecting sunlight and guiding ventilation.

[0028] Although details will be described later, by setting the main body 5 to the angle of inclination as described above, the ventilation opening 8 of the upper ventilation section 4 can be used to heat the heat shield panel 1 Below in between This will allow for smooth ventilation. However, the angle of this inclination may vary as long as it allows for smooth ventilation at the bottom.

[0029] Next, the lower ventilation section 6 will be described. The lower ventilation section 6 is a part that has ventilation openings 9 and is connected to the main body 5. In one form, the ventilation openings 9 of the lower ventilation section 6 allow the air coming down from the main body 5 to enter the space below the heat shield panel. in between It has a ventilation function.

[0030] Furthermore, the shape of the ventilation opening 9 of the lower ventilation section 6 can be in various forms, similar to the ventilation opening 8 of the upper ventilation section 4 described above. That is, circular openings may be arranged regularly, or they may be single square holes.

[0031] Furthermore, although details will be described later, air is released through the ventilation opening 9 of the lower ventilation section 6, below the heat shield panel. in between Wind is flowing in.

[0032] Furthermore, the first connection section 3 and the second connection section 7 are provided with multiple connection holes 10 for connecting to the corrugated metal roof 20 via a connecting member 22. The location and number of these connection holes 10 can vary, as long as they allow the heat shield panel 1 to be fixed to the corrugated metal roof.

[0033] <Regarding the layout and ventilation mechanism> next 、 The installation configuration and ventilation mechanism when the heat-shielding panel 1 is installed on the corrugated metal roof 20 will be described using Figures 2 and 3.

[0034] Figure 2 shows a perspective view of the heat shield panel 1 installed on the corrugated metal roof 20. As shown in Figure 2, The corrugated metal roof 20 has a convex flat surface 20a at the top of the convex part and a recessed flat surface 20c at the bottom of the recess, and between the convex flat surface 20a and the recessed flat surface 20c there is a convex inclined surface 20b that slopes from the recessed flat surface 20c toward the recessed flat surface 20c. The heat shield panel 1 is, The first connection portion 3 of the heat shield panel 1 is located on the protruding portion of the corrugated metal roof 20. flat The connection will be made along surface 20a.

[0035] Also, corrugated metal roof 20 Among the uneven structures one Convex part and Other adjacent to it In this configuration, one heat-shielding panel 1 is placed on one of the recesses between the protrusions.

[0036] However, corrugated metal roof 20 The width between the convex and concave parts, and the width of the heat shield panel 1 (Figure 2) The heat-shielding panel 1 shown in the diagram is an abridged version of the paper. Width in the left-right direction and the length in the shorter direction of the heat shield panel 1 If there is a sufficient difference between the two, a single heat-shielding panel 1 may be arranged on top of multiple recesses.

[0037] Furthermore, the heat-shielding panel 1 may be installed over the entire upper part of the corrugated metal roof 20 at the top of a building.

[0038] Next, Figure 3 shows a cross-sectional view of the corrugated metal roof 20 with the heat-shielding panel 1 connected. As shown in Figure 3, the heat-shielding panel 1 is connected to the protruding part of the corrugated metal roof 20. flat On surface 20a, the first connection part 3 and The adjacent overlapping connection part 3 other Connection of the second connection part 7 of the heat shield panel 1, etc. surface In this configuration, the connection is made via a connecting member 22 such as a bolt or nut.

[0039] Furthermore, the ventilation opening 8 of the upper ventilation section 4 and the ventilation opening 9 of the lower ventilation section 6 are connected to the first connection section 3 and Second connection section 7 including flat surface and The angle formed by The opening is angled upwards at approximately a 60° angle.

[0040] In this configuration of the heat shield panel 1, the air from the upper ventilation section 4 to the air below the heat shield panel Interval 1 Wind 13 flows into 2. At this time, the incoming wind 13 generally flows over the convex parts of the corrugated metal roof 20. Slope 2Moving along 0b towards the concave flat surface 20c, it continues straight onto the corrugated metal roof. 20 It moves along the concave flat surface 20c.

[0041] On the other hand, the space below the heat shield panel Interval 1 From the opposite side of the ventilation opening 8 of section 2, wind that has traveled along the top of the main body section 5 flows into the space 12 below the heat shield panel through the ventilation opening 9 of the lower ventilation section 6. 13 This is the space below the heat shield panel along the convex slope 20b. 12 Move downwards inside, and continue moving along the concave flat surface 20c.

[0042] Here, the lower ventilation section 6 is located below the first connection section 3 and is connected to the very bottom of the main body section 5. Therefore, the air coming down the main body section 5 13 The structure is designed to easily guide the air towards the vent 9, reducing the risk of the airflow becoming disordered.

[0043] Then, the wind that flows in from the upper ventilation section 4 13 and the wind that flowed in from the lower ventilation section 6 13 They collide near the center of the concave flat surface 20c and are lifted upwards (Figure 3). The page central part reference ). Then, each gust of wind 13 is directed towards the upper ventilation section 4 or the lower ventilation section 6. With this mechanism, the air in the space 12 below the heat shield panel is repeatedly stirred as the wind flows in, and the corrugated roof 2 Below 0 This makes it possible to suppress an excessive temperature rise in the internal space 14.

[0044] Furthermore, in this embodiment, the main body 5 Up This configuration also allows for the installation of solar panels. In this configuration, the temperature rise of the solar panels can be suppressed, enabling efficient power generation.

[0045] [2. Embodiment 2 of a heat-shielding panel according to one embodiment of the present invention] <About the structure> Next, another embodiment of the heat shield panel according to one embodiment of the present invention (hereinafter referred to as the second embodiment). It is called This section will discuss the following. Other embodiments of the heat shield panel according to one embodiment of the present invention include those shown in Figures 4 to 6.

[0046] Figure 4 to As shown, in this embodiment, the heat shield panel 30 is constructed by fastening screws or the like, connecting the metal members constituting the first main body support portion 31, the connecting portion 32, the upper ventilation portion 33, the second main body support portion 34, and the members constituting the main body portion 35. and The heat shield panel 30 comprises a first main body support portion 31, a connecting portion 32, an upper ventilation portion 33, a second main body support portion 34, and a main body portion 35. The connecting portion 32 is provided with at least one connecting hole 36.

[0047] The connection hole 36 is for the corrugated roof 50 convex part flat surface 50a These are parts that are connected via connecting members such as bolts or nuts.

[0048] Here, the heat shield panel 30 is connected to a metal plate of the main body 35 by fasteners, etc., by a bent metal plate having a first main body support part 31, a connecting part 32, an upper ventilation part 33, and a second main body support part 34. and Alternatively, one metal plate may be used. bend The plate is then processed and formed, including all of the aforementioned parts. processing It may be done in that way.

[0049] next Heat shielding panel 30 Each part will be described. The function of each part is as in the first embodiment. The same name With respect to similar parts, it is generally the same as that of the first embodiment.

[0050] First, the first main body support section 31 is adjacent to other Heat shielding panel 30 Main body 35 This is the part that supports it. In other words, the adjacent other By loading and fixing the lower part of the main body 35 of the heat shield panel 30 onto the upper part of the first main body support 31, Two adjacent The heat shielding panel 30 Connected to each otherIt will be done.

[0051] This adjacent other The heat shield panel 30 and the first main body support section 31 may be firmly fixed together using fastening members such as bolts and nuts.

[0052] Next, we will describe the connection part 32. The connection part 32 is a corrugated metal roof. 50 convex part Flat surface 50a This is the part that connects to the corrugated metal roof. As mentioned above, one or more connection holes 36 are drilled in the connection part 32, and the corrugated metal roof connects through the connection holes 36. 50 convex part Flat surface 50a It is connected to this.

[0053] Furthermore, the connecting portion 32 and the upper ventilation portion 33 and the main body portion 35, in a plan view when the heat shield panel 30 is installed on the corrugated roof 50, vertical Width (Figure 4) The width of the heat-shielding panel 30 shown in the paper is approximately in the vertical direction, and the length is in the longitudinal direction. ) are different, and compared to the main body 35, the connection part 32 and the upper ventilation part 33 The length is shorter This configuration is good. With this configuration, a corrugated metal roof 50 When multiple heat shielding panels 30 are installed, the main body 35 Front and back in the longitudinal direction A gap without a plate can be provided. The air can then exit from the space below the heat-shielding panel through this gap. However, the main body 35 can be installed closely together without this gap.

[0054] Furthermore, the connection part 32 has a ventilation opening 41 for airflow. Multiple (3) It is provided. each The shape of the ventilation opening 41 is, Book Embodiment So Although it is roughly rectangular in shape, it can be circular or elliptical, or have multiple small-diameter holes, or any other configuration as long as ventilation is possible.

[0055] Next, the upper ventilation section 33 will be described. The upper ventilation section 33 is provided with respect to the surface of the connecting section 32 which is substantially parallel to the horizontal plane, Bending angle Approximately 30°~approximately 60° It can be folded upwards as It is installed at an angle. There is. In the upper ventilation section 33A ventilation opening 42 is provided. The configuration of the ventilation opening 42 may be the same as that of the ventilation opening 41, with one or more circular holes, or with one or more square holes.

[0056] Also, in Figure 4, Connection part 32 The position of each ventilation opening 41 and Upper ventilation section 33 Each of the ventilation openings 42 is located almost adjacent to the others. In this configuration, the air released from the space 51 below the heat shield panel through the ventilation openings 41 45 It can be quickly moved into the adjacent ventilation opening 42.

[0057] Therefore, the wind can move through the heat-shielding panels 30 that are arranged in a series, one after the other, and the corrugated roof 50 This can significantly contribute to suppressing temperature rise.

[0058] Furthermore, the ventilation opening 42 directs airflow from diagonally above, below the main body 35. direction space under the heat-shielding panel 51 It has a ventilation function.

[0059] Next, the second main body support section 34 will be described. The second main body support section 34 is located in the upper ventilation section 33 The connection portion 32 is bent at approximately a right angle to the surface of the upper ventilation portion 33 on the opposite side from the side to which it is connected. connection done This is the part. The main body part 35 is on the second main body support part 34. One end in the width direction By loading the load, the second main body support section 34 has the function of supporting the main body section 35.

[0060] Furthermore, since the second main body support portion 34 or the main body portion 35 is located approximately directly above the upper ventilation portion 33 when the heat shield panel 30 is installed, covering the upper ventilation portion 33 prevents foreign matter from entering the ventilation opening 42 provided in the upper ventilation portion 33.

[0061] Furthermore, the second main body support part 34 or the main body part 35, contact Sequel 32 of The connection portion 32 may be extended directly upward to cover the upper part of the connection portion 32, thereby preventing foreign matter from entering the ventilation opening 41.

[0062] Next, the main body 35 will be described. The main body 35 is a roughly rectangular plate, and is a folded plate roof of the heat shield panel 30. 50 When installing to, Includes a convex flat surface 50a Across the horizontal plane The angle of inclination A range of approximately 30° to approximately 60° as They are arranged in an inclined manner.

[0063] At this angle of inclination, the main body 35 The corrugated metal roof is 50 Installation So By doing so, the main body 35 by It can block and reflect sunlight, and the ventilation opening 42 from Below the heat shield panel between 5 It is possible to guide the airflow into the interior.

[0064] Furthermore, because the main body 35 is inclined, the space between the air inlet 42 and the air outlet 41 narrows as the wind moves. This creates a nozzle effect in relation to the movement of the wind, causing the wind to be released to the outside with increased force from the air outlet 41.

[0065] Here, corrugated metal roof 50 Depending on the width of the corrugated sheet and other conditions, the inclination angle may be set beyond this range.

[0066] <Regarding the layout and ventilation mechanism> Next, the arrangement of the heat shield panel and the ventilation mechanism of this embodiment will be described using Figures 5 and 6. In this embodiment, the connection hole 36 of the connection part 32 and the protrusion of the corrugated roof 50 flat surface 50a and 43 are connected by a connecting member 43 such as a bolt.

[0067] In the heat shield panel 30 of this embodiment, first, air is released from the ventilation opening 42 of the upper ventilation section 33 to the air below the heat shield panel. between 5 Wind 45 flows into 1 (Figure 6). At this time, since the upper ventilation section 33 is arranged at an angle, the wind 45 from above the upper ventilation section 33 is directed to the space below the heat shield panel. between 5 1 is properly guided inside. In addition, the upper part of the upper ventilation section 33 is covered by the second main body support section 34 and the main body section 35. Yes, they are.The second main body support section 34 and the main body section 35 are located in the upper ventilation section 33 Ventilation opening 42 Wind passing through 45 Ventilated slope through which air flows By functioning as such, wind 45 Towards ventilation opening 42 Provide appropriate guidance.

[0068] And, below the heat shield panel between 5 The wind 45 that flows into 1 is below the heat shield panel between 5 After crossing the interior, it passes through the ventilation opening 41 provided in the connection part 32, and below the heat shield panel between 5 It is released to the outside from point 1.

[0069] Furthermore, in this configuration, the space below the heat shield panel between 5 Before being released to the outside from vent 41, below the heat shield panel between 5 The air is released to the outside through the narrower ventilation opening 41 rather than the wider space inside 1. Therefore, the air below the heat shield panel is intermittently released. between 5 Combined with the wind 45 flowing into 1, the air below the heat shield panel between 5 Pressure is applied to the airflow 45 inside 1. As a result, the nozzle effect accelerates the movement of the airflow 45, and the airflow 45 is properly released to the outside.

[0070] In this manner, the heat shield panel according to this embodiment 30 It has excellent heat-shielding properties.

[0071] [3. Embodiment 3 of a heat-shielding panel according to one embodiment of the present invention] <About the structure> Next, Embodiment 3 of a heat-shielding panel according to one embodiment of the present invention (Hereinafter referred to as the third embodiment) This will be described. The heat shield panel 60 in this embodiment is First Embodiment Or Second Embodiment Heat shielding panel 1,30 Similarly, although it is installed on a corrugated metal roof 70, 70 The orientation of the installation differs, and the recess of the corrugated metal roof 70 The extension directions of the section and the protrusion, respectively. against The long side of the heat shield panel is They are arranged perpendicularly to each other.

[0072] Specifically, as shown in Figure 7, the heat shield panel 60 consists of a first main support section 55, a connecting section 56, an upper ventilation section 57, a second main support section 58, and a main body section 59.

[0073] Furthermore, ventilation openings 73 and 74 are provided in the connecting section 56 and the upper ventilation section 57. As shown in one embodiment of Figure 7, the shape of the ventilation openings 73 and 74 is, for example, roughly rectangular, but they can be circular, elliptical, or a collection of small-diameter circular shapes, as long as ventilation is possible.

[0074] <Installation configuration and ventilation mechanism> Next, we will describe the specific arrangement of this embodiment. As shown in Figure 7, the heat shield panel 60 The connection part 56 is the flat part of the convex portion of the corrugated metal roof 70. flat surface 70a is connected via a connecting member 71 such as a fixing device.

[0075] At this time, as shown in Figure 7, the row of connection parts 56 of the heat shield panel 60 and the convex flat flat surface The row 70a is approximately orthogonal to the row 70a.

[0076] And the convex part of the corrugated metal roof 70 flat surface 70a Direction of extension In accordance with this, the first main body support section 55, the connecting section 56, the upper ventilation section 57, and the second main body support section 58 are arranged in order (each section sequentially covers the upper part of the upper flat section 70a of the convex part of the folded plate roof 70).

[0077] Because they are arranged in this manner, the wind flows along the main body 59 of the heat shield panel 60, from above to below the heat shield panel. between 7 2. It passes through the recessed space of the corrugated metal roof 70. In this case as well, the wind passes through the space below the heat shield panel. between 7 In section 2, air enters through the wide entrance and, as the wind progresses, The gap The opening narrows. As a result, the airflow pushes against each other, gaining momentum due to the nozzle effect as it exits the recess, and is released to the outside through the vent 73. This results in a configuration with good ventilation efficiency.

[0078] Also, the wind is below the heat shield panel. between 7 It is also possible to move within 2 in one direction (from left to right in Figure 7). Therefore, the heat shield panel according to this embodiment 60 It has excellent ventilation and provides sufficient temperature buffering effect.

[0079] In other words, in this embodiment, the movement of air occurs smoothly from left to right in Figure 7 by passing through the vents 73 and 74 and the space below the heat shield panel 72.

[0080] Furthermore, in this embodiment, although the ventilation openings 73 and 74 are shown adjacent to each other in Figure 7, the positions of the ventilation openings 73 and 74 may be offset to prevent mixing of the air passing through the ventilation opening 73 and the air passing through the ventilation opening 74.

[0081] [4. Embodiment 4 of a heat-shielding panel according to one embodiment of the present invention] <About the structure> Next, Embodiment 4 of a heat-shielding panel according to one embodiment of the present invention (Hereinafter referred to as the fourth embodiment) This will be explained using Figure 8. As shown in Figure 8, the heat shield panel 80 in this embodiment is not intended to be mounted on a corrugated metal roof as described above, but rather to be installed on a flat roof such as a flat roof.

[0082] Although Figure 8 only shows one weight 90 connected to the connection hole 91 of the heat shield panel 80, the two connection holes 91 in the heat shield panel 80 are considered as one set, and a weight 90 is connected to each connection hole 91 in each set. Therefore, for example, in the heat shield panel 80 shown in Figure 8, four weights 90 will be connected.

[0083] Furthermore, although not shown for the heat shield panel 80, when installing the heat shield panel 80 on a flat roof, each heat shield panel 80 is as shown in Figure 8. Page The panels are arranged in a manner where multiple panels are placed adjacent to each other, from left to right.

[0084] Next, the heat-shielding panel 80 will be described. This heat-shielding panel 80 is used by first placing a weight 90, such as a water tank weight, on the top of a flat roof, and then fixing the weight 90 and the heat-shielding panel 80 together with connecting members 95 such as bolts or nuts.

[0085] Furthermore, the weight 90 can be attached to a flat roof, and as long as a heat-shielding panel can be fixed to its upper part, its size, shape, material, etc., can be freely designed.

[0086] Furthermore, the structure of the heat shield panel 80 is generally similar to that of the heat shield panel 30 (Figure 4) described above. Specifically, the heat shield panel 80 comprises a first main body support section 81, a connecting section 82, an upper ventilation section 83, a second main body support section 84, and a main body section 85.

[0087] Furthermore, the structure and function of the first main body support section 81, the upper ventilation section 83, the second main body support section 84, and the main body section 85 are as described above. According to the second embodiment It is the same as the heat-shielding panel 30.

[0088] Furthermore, the connecting portion 82 has one or more connecting holes 91 for connecting to the weight 90, and is fixed at this portion by fasteners such as bolts or nuts. The number and form of the connecting holes 91 are not limited as long as they are in a manner that allows for sufficient fixing to the weight 90.

[0089] Furthermore, the connection section 82 is provided with a ventilation opening 86 for allowing air to circulate. As shown in one embodiment of Figure 8, the shape of the ventilation opening 86 is, as an example, roughly rectangular, but it can be circular, elliptical, or a collection of small-diameter circular shapes, as long as it allows for ventilation.

[0090] Furthermore, the upper ventilation section 83 is provided with ventilation openings 87 for allowing air to circulate. As shown in one embodiment of Figure 8, the shape of the ventilation openings 87 is, for example, roughly rectangular, but they can be circular, elliptical, or a collection of small-diameter circular shapes, as long as ventilation is possible.

[0091] <Regarding the layout and ventilation mechanism> next, Shielding panel 80 according to the fourth embodiment The arrangement and ventilation mechanism will be described using Figure 9. Figure 9 is a cross-sectional view when a weight 90 is placed on a flat roof and a heat-shielding panel 80 is placed on top of the weight 90.

[0092] As shown in Figure 9, the heat shield panel 80 is fixed to the weight 90 by the top of the weight 90 and by, for example, two fixing points per connection part 82. The weight 90 is, for example, a water tank weight, but it may be of any other form as long as it can be fixed in place.

[0093] In the heat-shielding panel 80 arranged in this manner, air 96 flows from left to right in Figure 9. That is, since the main body 85 is arranged at an angle and the upper ventilation section 83 has an opening 87, air 96 flows into the space below the heat-shielding panel from the opening 87 of the upper ventilation section 83.

[0094] Furthermore, since the weights 90 are placed at intervals below the heat shield panels 80, space is created on both sides of the weights 90 for air 96 to circulate, allowing for sufficient airflow.

[0095] And, below the heat shield panel Between, The wind 96 that has passed through both sides of the weight 90 is released to the outside through the ventilation opening 86 of the connection part 82 of the adjacent heat shield panel 80. At this time, it may mix with the wind 96 flowing in from the ventilation opening 87 of the upper ventilation part 83 of the adjacent heat shield panel 80, but one after the other, as shown in Figure 9 Page The wind 96 moves from left to right and is eventually released entirely to the outside, thus providing a sufficient temperature change buffering effect.

[0096] Furthermore, as shown in Figure 9, in this embodiment, the airflow path for the wind 96 is stable in one direction, and appropriate airflow guidance is provided. Also, for example, Figure 9 Page When wind 96 blows from right to left, the inclined main body 85 suppresses the inflow of wind 96, and the area below the heat shield panel in between This obstructs ventilation. As a result, the direction of ventilation is stabilized, and the heat shield panel of this embodiment has a sufficient temperature buffering effect.

[0097] Furthermore, the space below the heat-shielding panel is the air into which the wind flows in as the wind 96 enters. The gap It gradually shrinks. As a result, as the inflow of wind 96 progresses, pressure is applied to the wind 96, increasing its velocity, and due to the nozzle effect, the vigorously flowing wind 96 is released from the vent 87.
