Abstract
Description
Technical Field
[0001] The present invention relates to a heat insulation panel for covering a folded plate roof and a heat insulation structure using the heat insulation panel.
Background Art
[0002] A folded plate roof is a concavo-convex structure widely used for the roofs of large warehouses, supermarkets, etc. Since the folded plate roof is formed in a concavo-convex shape, it has excellent drainage and can be installed at low cost because it does not require a base. On the other hand, such a folded plate roof is mainly manufactured using a galvanized steel sheet (registered trademark). When sunlight directly irradiates the folded plate roof, the roof itself easily becomes very hot, and consequently, the internal space of the building directly under the folded plate roof also easily becomes hot.
[0003] To solve such problems, various measures have been taken to prevent the folded plate roof from getting hot. For example, by providing through-holes with a diameter of approximately φ100 mm at regular intervals in a sheet made of synthetic resin that covers the folded plate roof, the sheet is given air permeability and ventilation, and by allowing air to flow through the space between the folded plate roof and the sheet, a technique for preventing the folded plate roof from getting hot (Patent Document 1), or by providing a certain gap at the joint between sheets that cover the folded plate roof, and allowing air to flow through the internal space between the folded plate roof and the sheet and the gap between the sheets, a technique for reducing the temperature of the internal space of the building under the folded plate roof (Patent Document 2), etc. exist.

Summary of the Invention
Problems to be Solved by the Invention
[0005] However, the conventional heat insulation mechanism is not sufficient to cool the folded-plate roof. In recent years, due to the global warming phenomenon, a significant increase in the average temperature has been observed. As a result, the cost of cooling expenses has increased, and consequently, the CO2 emissions associated with power consumption have also increased. For these reasons, the demand for products that consider the global environment has been increasing in recent years.
[0006] In particular, the folded-plate roof is composed of metal panels and is often installed in factories and the like where machines and the like are in operation and the room temperature is likely to rise. Therefore, the cooling cost is higher in factories and the like than in ordinary houses.
[0007] The present invention provides a heat insulation panel that covers the upper part of the folded-plate roof, aligns the ventilation direction between the convex and concave portions of the folded-plate roof, enables ventilation in a specific direction, and thus helps prevent the temperature of the folded-plate roof from rising.
Means for Solving the Problems
[0008] The present invention is a heat insulation panel that covers a regular concavo-convex structure including a folded-plate roof. The heat insulation panel is connected to the concavo-convex structure via a connecting member near the flat portion at the upper part of the convex portion of the concavo-convex structure, covers up to the middle part of the side surface of the convex portion of the concavo-convex structure along the shape of both side surfaces of the convex portion of the concavo-convex structure, then extends parallel to the flat portion of the bottom surface of the concave portion of the concavo-convex structure, and further bends downward at approximately 45° obliquely at both ends thereof.
[0009] The present invention also relates to a heat insulation structure using a heat insulation panel, characterized in that by covering the concavo-convex structure with the heat insulation panel according to claim 1, a temperature buffer air layer is generated in the space between the heat insulation panel and the concavo-convex structure.
[0010] The present invention also relates to a heat insulation panel for covering a regular concavo-convex structure including a folded plate roof, wherein the heat insulation panel is connected to the concavo-convex structure via a connecting member near the upper flat part of the convex part of the concavo-convex structure, and a part of the heat insulation panel is smoothly recessed to form a cavity, thereby forming a hole that is substantially a perfect circle in plan view. The hole is regularly arranged along the concave part of the concavo-convex structure and at a substantially straight upper part of the concave part. The heat insulation panel is characterized by this arrangement.
[0011] The present invention also relates to a heat insulation structure using a heat insulation panel, characterized in that by covering the concavo-convex structure with the heat insulation panel according to claim 3, a temperature buffer air layer is generated in the space between the heat insulation panel and the concavo-convex structure.
[0012] The present invention also relates to a heat insulation panel arranged on the roof part of a building having a roof part with a regular concavo-convex structure, and having a function of buffering temperature changes in the internal space of the building. When the heat insulation panel is arranged on the roof part, it is arranged along the side inclined surface part of the roof part with the concavo-convex structure and near the directly upper part of the side inclined surface part. It has a ventilation vent for ventilation, a ventilation vent covering part arranged in a certain inclined shape above the ventilation vent for covering the ventilation vent and guiding the ventilation direction, and a connection hole for connecting to the upper flat part of the convex part of the roof part. The heat insulation panel is characterized by these features.
[0013] The present invention also relates to a heat insulation structure in which the heat insulation panel according to claim 5 is covered on the concavo-convex structure.
[0014] The present invention also relates to the heat insulation structure according to claim 6, characterized in that a solar panel is arranged on the upper part of the flat part of the heat insulation panel.
Advantages of the Invention
[0015] According to the present invention, a significant heat insulation effect can be obtained in a folded-plate roof. Therefore, it becomes possible to suppress the rise in air temperature in the internal space located under such a folded-plate roof. Further, it has a structure considering a ventilation mechanism, shielding of sunlight, etc., and has a high cooling effect. As a result, a significant cost reduction due to an energy-saving effect or the like can be expected, and it is also friendly to the global environment. Further, the product of the present invention is excellent in design, and even when disposed on a folded-plate roof, its aesthetic appearance is not lost.

Embodiments for Carrying Out the Invention
[0017] In the present invention, a heat insulation panel having a structure that is connected to a folded-plate roof via a connecting member near the flat part above the convex part of the folded-plate roof, covers up to the middle part of the side surface of the convex part of the folded-plate roof along the shape of both side surfaces of the convex part of the folded-plate roof, extends parallel to the horizontal plane, and further bends downward at approximately 45° obliquely at both ends thereof is covered on the folded-plate roof for heat insulation. Further, as another heat insulation panel, it is connected to the folded-plate roof via a connecting member near the flat part above the convex part of the folded-plate roof, and a part of such a heat insulation panel is smoothly recessed to form a cavity part, thereby forming a substantially circular hole part. The hole part is covered on the folded-plate roof with a heat insulation panel that is regularly arranged directly above the concave part along the concave part of the uneven structure, thereby providing a heat insulation sheet for the folded-plate roof with a high cooling effect.
[0018] [1. Structure of the heat insulation panel according to an embodiment of the present invention] First, an embodiment for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which a heat insulation panel 3 is disposed so as to cover a folded-plate roof (this embodiment is referred to as Embodiment 1). In such a figure, three rows of heat insulation panels 3 are disposed for three rows of convex parts of the folded-plate roof, but usually, all convex parts of the folded-plate roof are covered and disposed for use. Further, in FIG. 1, only the depth of the folded-plate roof is shown up to the middle part, but the convex part of the folded-plate roof extends to the back part of the drawing, and the heat insulation panel also covers the convex part of the folded-plate roof accordingly.
[0019] FIG. 2 is a cross-sectional view during use when a heat insulation panel is covered on a folded-plate roof. Such a figure is a view of the cross-section of the perspective view of the folded-plate roof in FIG. 1 seen from the front. One heat insulation panel and the folded-plate roofs on both sides thereof are described, but such a part is a part of the folded-plate roof, and the heat insulation panel is covered and disposed over the entire folded-plate roof.
[0020] Figure 3 is a side view of the present heat insulation panel. The left side view and the right side view are also similar figures. Figure 4 is a bottom view of the present heat insulation panel and a plan view of the present heat insulation panel. Figure 5 is a front view of the present heat insulation panel and a perspective view of the present heat insulation panel. Also, the rear view is the same figure as the front view of Figure 5(a).
[0021] Figure 6 is a perforated heat insulation panel according to another embodiment of the present invention, and is a perspective view of the state of covering a folded plate roof with the perforated heat insulation panel. Although three rows of folded plate roofs are shown in such a figure, it varies depending on the size of the folded plate roof to be covered and the size of the perforated heat insulation panel. Also, although the depth is shown only partway, it is in a form that covers all the folded plate roofs. Figure 7 is a cross-sectional view during use when the perforated heat insulation panel is covered on the folded plate roof. In such a figure, the through holes and bolts are shown at the positions where the cross section is taken. Figure 7 is a cross-sectional view during use when the perforated heat insulation panel is covered on the folded plate roof. In such a figure, the through holes and bolts are shown at the positions where the cross section is taken.
[0022] Figure 8 is a top view of a single perforated heat insulation panel according to another embodiment of the present invention. The dotted line portion of the through hole indicates the portion where the panel begins to fold smoothly and begins to form the through hole. Figure 9 is a bottom view of a single perforated heat insulation panel. Figure 10 is a side view of the perforated heat insulation panel. The left side view and the right side view of such a perforated heat insulation panel are also the same figures as Figure 10.
[0023] Next, the structure of the article constituting the present invention will be described with reference to FIGS. 1 to 5. Figure 1 is the heat insulation panel 3 described in claim 1 and claim 2. Such a heat insulation panel 3 has a structure in which a vertically long rectangular metal panel is bent. Note that the type of metal of such a panel is not limited as long as it has durability, toughness, etc. Also, the material of such a heat insulation panel 3 may be a synthetic resin or the like. And a cushion material or the like is disposed as a connecting member 4 on the flat portion 5a of the upper surface of the convex portion of the folded plate roof, and the heat insulation panel 3 is loaded thereon via such a cushion material. The thickness of such a cushion material is approximately 5 mm. Also, such a cushion material is a synthetic resin product such as urethane, for example, but the type is not limited as long as it has a certain degree of firmness, durability, heat retention, etc.
[0024] And, the flat portion 3a on the upper surface of the heat insulation panel 3 has a planar structure, and the surface of such flat portion 3a on the upper surface of the heat insulation panel is parallel to the flat portion 5a on the upper surface of the convex portion of the folded plate roof 5. Also, at such a portion, on the flat portion 5a on the upper surface of the convex portion of the folded plate roof, along the longitudinal direction of the heat insulation panel 3 at regular intervals, the heat insulation panel 3, the connecting member 4, and the flat portion 5a on the upper surface of the convex portion of the folded plate roof are firmly fixed by bolts 1 and nuts 2, etc. The bolt 1 is driven upward from the lower part of the folded plate roof 5, and has a structure in which the folded plate roof 5, the connecting member 4, and the heat insulation panel 3 are sandwiched from below and fixed with the nut 2. In addition, in this embodiment, it is fixed with bolts and nuts, but any type of fixing device that can be fixed in the same manner is acceptable regardless of its type.
[0025] And, such heat insulation panel 3 bends downward at both end portions of the flat portion 5a on the upper surface of the convex portion of the folded plate roof so that the surface of the heat insulation panel 3 and the inclined surface portion 5b on the side of the folded plate roof are parallel. And such heat insulation panel 3 is parallel to the surface of the inclined surface portion 5b on the side of the folded plate roof and extends downward along such a side surface. A connecting member 4 is continuously arranged also at such a portion, and also at such an inclined surface portion, the connecting member 4 fills the gap space portion between the heat insulation panel 3 and the folded plate roof 5.
[0026] Furthermore, such heat insulation panel 3 extends horizontally (heat insulation panel side extension portion 3c) so as to be parallel to the ground after running parallel along the middle portion of the inclined surface portion 5b on the side of the folded plate roof (heat insulation panel inclined surface portion 3b). Then, it bends obliquely downward at 45 degrees directly above the bottom surface of the flat portion 5c at the bottom of the concave portion of the folded plate roof to form both end portions (heat insulation panel end portion 3d). There is no other member connected to such heat insulation panel end portion 3d, and such heat insulation panel end portion 3d has an open structure in the internal space 6 of the concave portion of the folded plate roof. At such heat insulation panel end portion 3d, a groove structure portion 7 is formed by one heat insulation panel end portion 3d and another adjacent heat insulation panel end portion 3d. By allowing the wind to ventilate between such groove structure portions 7, it is possible to lower the temperature of the folded plate roof 5.
[0027] Next, with reference to FIGS. 6 to 10, the perforated heat-insulating panel 11 according to another embodiment of the present invention, which is described in claims 3 and 4, will be described (this embodiment is referred to as Embodiment 2). Such a perforated heat-insulating panel 11 is a vertically long rectangular metal panel, and its size is approximately 600 mm in length and approximately 1000 mm in width. Such a perforated heat-insulating panel 11 has a structure in which through-holes 13 are regularly provided. Such through-holes 13 are perfect circles with a diameter of approximately φ30 mm, and are arranged at intervals of approximately 100 mm horizontally along the flat portion 5c of the bottom surface of the corrugated roof recess. Further, as the shape of such through-holes 13, the panel portion 11a of the perforated heat-insulating panel is smoothly recessed downward at the through-hole 13 portion, and the perforated heat-insulating panel recessed portion 11b floating in the corrugated roof recess space 14 forms the hole portion.
[0028] Also, similar to the above-described heat-insulating panel 3, such a perforated heat-insulating panel 11 is arranged at the flat portion 5a on the upper surface of the corrugated roof convex portion so as to cover the upper portion of the intermediate member 12 via the intermediate member 12. The thickness of such an intermediate member is approximately 5 mm. And at such a portion, the bolt 1 is driven vertically upward from below the flat portion 5a on the upper surface of the corrugated roof convex portion to penetrate the intermediate member 12 and the perforated heat-insulating panel 11. Then, the intermediate member 12 and the perforated heat-insulating panel 11 are sandwiched and fixed by the nut 2. Such a fixing portion is located directly above the flat portion 5a on the upper surface of the corrugated roof convex portion, and is arranged at a position 200 mm inward from both lateral ends of such a perforated heat-insulating panel 11. The number of such fixing portions depends on the size of the corrugated roof on which such a perforated heat-insulating panel 11 is arranged, but in the case of one perforated heat-insulating panel 11 with a size of approximately 600 mm in length and approximately 1000 mm in width as described above, it is about 8 locations.
[0029] Also, such a perforated heat-insulating panel 11 may be in other similar forms. That is, it is a heat-insulating panel with a length of 1000 mm and a width of 1000 mm, and through-holes are arranged at intervals of 100 mm in length and 200 mm in width. In such a heat-insulating panel, there is no connecting portion such as a corrugated roof, and it is directly covered on the upper part of the building and used without fixing such a heat-insulating panel.
[0030] [2. Mechanism for Low Temperature in One Embodiment of the Present Invention] Next, the mechanism of temperature reduction when the heat insulation panel of the present invention is used will be described. First, it is about the heat insulation method described in claim 1 and claim 2. Regarding the mechanism of temperature reduction, there is temperature reduction due to ventilation in the internal space 6 of the corrugated roof recess, and a heat insulation effect on the corrugated roof recess space.
[0031] First, the mechanism of temperature reduction due to ventilation in the groove structure part 7 will be described with reference to FIG. 2. For the internal space 6 of the corrugated roof recess, wind flows in from above the groove structure part 7. Also, the wind flowing in from above the heat insulation panel 3 moves downward along the heat insulation panel inclined surface 3b, the heat insulation panel side extension part 3c, and the heat insulation panel end part 3d in this order from the corrugated roof convex part. Then, it flows into the internal space 6 of the corrugated roof recess of the corrugated roof recess from the groove structure part 7. At this time, the wind gathers toward the narrower groove structure part 7 from above the heat insulation panel 3 and passes through the gap between the heat insulation panel end parts 3d. Therefore, the inflowing winds gather and pressure is generated. And when the wind passes through the gap between the heat insulation panel end parts 3d and exits into the wide internal space 6 of the corrugated roof recess, the outflow speed increases due to the nozzle effect. Therefore, the wind flowing into the internal space 6 of the corrugated roof recess from the groove structure part 7 moves vigorously toward the vicinity of the flat part 5c of the bottom surface of the corrugated roof recess, reaches the corrugated roof side inclined surface 5b, and then is rolled up and moves toward the upper part inside the internal space 6 of the corrugated roof recess. And the air heated in the internal space 6 of the corrugated roof recess is pushed by the wind flowing in later and moves to the upper external space from the end part of the heat insulation panel 3 at the end of the corrugated roof and is discharged as heated air. By these mechanisms, the air in the internal space 6 of the corrugated roof recess is stirred in the internal space 6 of the corrugated roof recess, and also, the heated air in the internal space 6 of the corrugated roof recess is discharged to the outside, preventing excessive temperature rise in the internal space 6 of the corrugated roof recess. As a result, it is possible to prevent the temperature rise in the internal space part below the corrugated roof.
[0032] Next, the heat insulation effect on the folded-plate roof will be described. The heat insulation panel 3 used in FIGS. 1 and 2 has both of its ends inclined downward at approximately 45°. Therefore, when sunlight enters obliquely with respect to the folded-plate roof 5, a part of the sunlight is shielded by the heat insulation panel side extension 3c and the heat insulation panel end 3d of the heat insulation panel 3, and the amount of sunlight incident on the internal space 6 of the folded-plate roof recess is reduced. As a result, many shaded areas are generated in the internal space of the folded-plate roof recess, and the temperature rise of the internal space 6 of the folded-plate roof recess can be suppressed. As a result, it is possible to expect a lower temperature in the internal space below the folded-plate roof. Here, since the heat insulation panel end 3d is inclined downward at approximately 45°, it has a structure that can maintain a sufficient air inflow function and obtain an appropriate heat insulation effect.
[0033] Next, regarding the heat insulation method described in FIGS. 6 and 7 etc., the mechanism of temperature reduction will be described. Also in the perforated heat insulation panel 11, air flows in from above the through hole 13 of the perforated heat insulation panel 11. Further, since the through hole 13 is smoothly recessed, the air flows in along the perforated heat insulation panel recessed portion 11b that bends smoothly toward the through hole 13. Here, since the perforated heat insulation panel recessed portion 11b is formed in a curved shape and smoothly, smooth ventilation toward the through hole 13 is promoted from above the perforated heat insulation panel 11. Further, since the through hole 13 has a structure in which the hole diameter smoothly contracts from the upper part to the lower part, the reverse flow of air from the lower direction to the upper direction can be reduced, and the one-way ventilation direction can be more ensured. For this reason, the air passage becomes clear, resulting in a sufficient cooling effect.
[0034] Furthermore, since the through hole 13 has a structure in which the hole diameter is large at the upper part and small at the lower part, when air flows into the through hole 13 from above, pressure is applied because it enters from a wider part toward a narrower part. Therefore, when the air flows out through the through hole 13 and toward the folded-plate roof recess space 14, the outflow speed increases due to the nozzle effect. As a result, the air existing in the folded-plate roof recess space 14 is more agitated.
[0035] The air flowing in from the through-hole 13 directly moves towards the flat part 5c on the bottom surface of the corrugated roof recess, and a part of the inflowing air hits near the flat part 5c on the bottom surface of the corrugated roof recess and is lifted up, stirring the air in the corrugated roof recess space 14. Then, it is discharged to the outside as heated air through the through-hole 13 of the perforated heat insulation panel 11 at the end of the corrugated roof. With such a mechanism, the perforated heat insulation panel 11 realizes sufficient low temperature in the internal space below the corrugated roof.
[0036] Also, regarding the heat insulation effect of the heat insulation method described in FIGS. 6 and 7, since the through-hole 13 is formed smoothly in a curved shape, when sunlight enters obliquely at such a part, a part of the sunlight incident on the curved surface part can be blocked. Such a mechanism for blocking sunlight has a larger sunlight shielding effect compared to the case where the through-hole 13 is formed in a straight line because the through-hole 13 is formed smoothly in a curved shape.
[0037] To summarize the above, the curved surface part of such a through-hole 13 has a structure with extremely high cooling effect that combines both functions of obtaining a sufficient ventilation part for air and a heat insulation effect for sunlight. As a result, the temperature rise in the corrugated roof recess space 14 can be suppressed.
[0038] [3. Another Embodiment of the Present Invention (Embodiment 3)] Next, an embodiment of the present invention will be described. In another embodiment of the present invention, it is in the form shown in FIG. 11 (this embodiment is referred to as Embodiment 3).
[0039] A cross-sectional view when Embodiment 3 is disposed on the corrugated roof is shown in FIG. 12. As shown in FIG. 12, the heat insulation panel 21 of Embodiment 3 is disposed on the corrugated roof 20 in contact with the flat part 20c on the bottom surface of the corrugated roof recess of the corrugated roof 20. At this time, the heat insulation panel 21 is disposed substantially parallel to the entire corrugated roof 20 (as an example, when the entire corrugated roof is disposed substantially parallel to the horizontal plane, the heat insulation panel 21 is also disposed substantially parallel to the horizontal plane).
[0040] The heat insulation panel 21 is connected to the flat portion 20a on the upper surface of the convex portion of the folded plate roof 20 via other connection members 22 such as bolts and nuts, similar to the other embodiments (Embodiment 1 and Embodiment 2) described above. As one aspect, these connection members 22 are regularly provided at regular intervals along the flat portion 20a on the upper surface of the convex portion. However, as long as the heat insulation panel 21 can be fixed, the position where the connection members 22 are provided does not matter in terms of their type.
[0041] In addition, near the flat portion 20a on the upper surface of the convex portion of the heat insulation panel 21, a ventilation opening 23, which is a hole for ventilation or air flow, is provided. The position of such a ventilation opening 23 is approximately the directly upper part of the side inclined surface portion 20b. This ventilation opening 23 is provided along the side inclined surface portion 20b such that, in a plan view of the entire heat insulation structure, a part of the side inclined surface portion 20b overlaps with the position of the ventilation opening 23, that is, the part of the side inclined surface portion 20b and the ventilation opening 23 are substantially parallel.
[0042] Here, as an example, the shape of the ventilation opening 23 may be a substantially rectangular shape as shown in FIG. 13, or it may be a mode in which a plurality of circular openings are provided along the upper part of the side inclined surface portion 20b. Also, the ventilation openings 23 may be provided continuously along the upper part of the side inclined surface portion 20b, or parts without the ventilation openings 23 may be regularly provided.
[0043] In addition, above the ventilation opening 23 of the heat insulation panel 21, a ventilation opening covering portion 24 that covers the ventilation opening 23 is disposed (FIG. 12). As an example, the ventilation opening covering portion 24 starts from a contact portion 25, which is a portion where the heat insulation panel 21 contacts the flat portion 20a on the upper surface of the convex portion, and extends in an inclined manner toward the side opposite to the connection member 22 from the contact portion 25.
[0044] Also, as an example, the inclination angle of this ventilation opening covering portion 24 forms an angle of approximately 45 degrees with the main body portion of the heat insulation panel 21.
[0045] The ventilation opening covering portion 24 that covers this ventilation opening 23 is not provided at a portion without the ventilation opening 23.
[0046] Further, this vent covering portion 24 may be formed by bending a part of the heat insulating panel 21, or may be provided by arranging a new metal part.
[0047] Next, the mechanism of the temperature change buffering function of the building interior space 30 when the heat insulating panel 21 of Embodiment 3 is arranged will be described.
[0048] First, the ventilation mechanism will be described. As shown in FIG. 12 which is a cross-sectional view of the heat insulating panel 21 and the folded plate roof 20, the wind 31 blowing from above the heat insulating panel 21 hits the vent covering portion 24 and enters the lower space 26 of the heat insulating panel. At this time, since the vent covering portion 24 is provided inclined at approximately 45° with respect to the heat insulating panel 21, an appropriate amount of wind enters the lower space 26 of the heat insulating panel.
[0049] The wind that has entered the lower space 26 of the heat insulating panel enters the interior of the lower space 26 of the heat insulating panel, and then descends along the side inclined surface portion 20b within the space of the lower space 26 of the heat insulating panel. Then, on the flat portion 20c of the bottom surface of the recess of the folded plate roof, when the wind collides with the other wind flowing into the same lower space 26 of the heat insulating panel, the mutual winds rise to the upper part within the lower space 26 of the heat insulating panel and return to the side where the wind has flowed in.
[0050] Due to the mechanism as described above, the air within the lower space 26 of the heat insulating panel is constantly stirred. In addition, the inflowing air is discharged to the external space from the part where the lower space 26 of the heat insulating panel, which is the end of the folded plate roof, is exposed to the external space.
[0051] Due to the mechanism as described above, the air within the lower space 26 of the heat insulating panel is constantly stirred, so the interior space 30 of the building under the folded plate roof does not experience excessive temperature rise.
[0052] In addition, since the sunlight itself is reflected by the heat insulating panel 21, the heat insulating panel 21 itself has a buffering function of alleviating the temperature rise of the building interior space 30.
[0053] Also, as another usage example of Embodiment 3, as shown in FIG. 14, a photovoltaic panel 28 may be provided on a flat portion 27 in the heat insulation panel 21 that does not have a connecting member 22, a vent 23, and a vent covering portion 24. In such a mode, ventilation through the vent 23 can prevent excessive temperature rise of the photovoltaic panel 28 and contribute to an increase in the power generation efficiency of solar power generation.
[0054] Incidentally, as an example, the size of this heat insulation panel 21 has a lateral width (the direction perpendicular to the convex portions of the folded plate roof is defined as the lateral direction) corresponding to one interval between the convex portions of the folded plate roof, but it may also be a length arranged across a plurality of convex portions. Also, the vertical width size is, for example, approximately 1000 mm, but various sizes are acceptable as long as it can be arranged on the folded plate roof.
[0055] Therefore, the arrangement mode of the folded plate roof may be a single large plate structure as shown in FIG. 14, or a mode in which a plurality of short plates are combined and arranged side by side.
[0056] [4. Advantages of the Present Invention, etc.] Next, the advantages of the heat insulation panel of the present invention product will be described. As described above, by using the heat insulation panel of the present invention, it is possible to lower the temperature of the internal space under the folded plate roof.
[0057] Regarding the temperature change during the installation of the heat insulation panel, according to the temperature measurement that actually measured the temperature drop, the temperature of the external space was lowered by 6°C compared to the installation of this heat insulation panel. In this regard, it can be said that the heat insulation panel of the present invention product has a sufficient cooling effect.
[0058] Also, the heat insulation panel of the present invention product only needs to be installed once and does not require replacement of the device due to seasonal changes. Therefore, it does not require much labor for facility management.
[0059] Also, once the heat insulation panel of the present invention product is installed, it can constantly lower the temperature of the space under the heat insulation panel. Therefore, compared to cooling by a cooling device such as a cooler, the cost is low and it is economically excellent.
[0060] In addition, the corrugated roof is often installed in facilities such as factories that operate at high temperatures. Therefore, by arranging such heat insulation panels, it is possible to expect a reduction in large-scale cooling costs due to the low-temperature effect. In this regard, according to the present invention, it is particularly cost-effective in terms of power costs and is economically excellent.
[0061] Moreover, such heat insulation panels are also excellent in terms of CO2 reduction costs. That is, the amount of CO2 required for the low-temperature operation of such a corrugated roof is only the amount of CO2 generated from the power energy required during product manufacturing, etc., and a significant reduction in the amount of CO2 can be expected compared to the amount of CO2 generated when continuously cooling using a cooler or the like. In this regard, the product of the present invention is environmentally friendly and highly contributes to a sustainable society.
[0062] In addition, in the heat insulation panel 3 described in claim 1, a corrugated roof recess is linearly opened in the gap between the heat insulation panels. Therefore, during cleaning, it is possible to easily clean by pushing a broom or the like into such a gap and scraping. In this regard, the product of the present invention is excellent in convenience.
[0063] In addition, the heat insulation panel 3 described in claim 1 has a structure in which a corrugated roof recess is linearly opened in the gap between the heat insulation panels. Therefore, when the wind ventilates, the ventilation directions are aligned and ventilate in one direction. As a result, the air movement in the corrugated roof recess space part is smoothly performed, and a sufficient cooling effect can be exerted.
[0064] In addition, the perforated heat insulation panel 11 described in claim 3 may be connected to the corrugated roof convex part and a through hole may be arranged directly above the corrugated roof recess. Therefore, it can be adapted to the size of the corrugated roof to be used and the size etc. can be flexibly changed for use, and it is easy to use. Moreover, when using the heat insulation panel of the product of the present invention, it is only necessary to cover the existing corrugated roof from above, so that the addition work can be easily performed. Also in this regard, it is excellent in convenience.
[0065] Regarding the perforated heat insulation panel 11 described in claim 3, as long as it is a structure with a flat part of a certain area, it can be disposed by simply covering the target structure with the invention product. Therefore, the object of use is not limited to the folded-plate roof, and it is user-friendly.
[0066] Also, the perforated heat insulation panel 11 described in claim 3 may be disposed vertically along the wall. Even in such an embodiment, a gap is formed between the perforated heat insulation panel 11 and the wall, and it is possible to expect a temperature drop by allowing the wind to ventilate through such a gap portion.
[0067] Also, the heat insulation panel 3 described in claim 3 is excellent in design. Therefore, the appearance of the building where such a heat insulation panel 3 is disposed does not impair the aesthetics and blends in with the surrounding scenery. In this regard, the heat insulation panel 3 of the present invention has commercial value.
[0068] The above-described embodiments are examples of the present invention, and the present invention is not limited to the above-described embodiments. Therefore, it goes without saying that various changes can be made according to the design and the like as long as the technical idea according to the present invention is not deviated from even outside the above-described embodiments. Also, the effects described in this embodiment are merely examples, and there may be other effects.
