[Prior Art] Previously, the roof of a building or building, or a building such as a work waste or warehouse, was usually directly exposed to light, so that the roof would become hot due to the direct sunlight of the sun, and the heat was transmitted to the interior. It also becomes hot. In particular, metal roofs such as folding, roofing, or galvanized iron roofs have a marked increase in temperature: when the indoor temperature is high, the operating time of air conditioners is increased. , while increasing the use of electricity, and related to the warming of the earth. Good countermeasures for high temperature, such as ventilation of the space on the back of the roof to change the oxygen to cover the influence of the roof. In addition, the house itself is made into a heat-proof structure, and the heat conducted by the roof is shielded from the rise of =. ...the degree of construction

As a result of the need to incorporate heat-preventing materials, the construction cost will increase. X. When the roof of the built building is constructed, it becomes a whole roof reconstruction, and the construction cost becomes high. Therefore, any method is difficult to construct in a building such as a factory, a large shop, a warehouse, or a garage, especially when using a metal roof made of corrugated board or folding board, because the sun is directly exposed to the sun. The change is quite southerly and affects the interior, so the effect is also problematic. • X ′ also has a method of coating a roof with a heat-resistant coating that reflects light and the like to reduce heat absorption. However, since the heat-resistant paint reflects light, it reflects light to an adjacent building or road, causing the temperature to rise and being dazzled by the reflected light. Then, when the heat-resistant paint is applied to the roof, the surface area of the roof is usually larger than the flat area. Therefore, it is necessary to apply a coating area of 1.5 times or more depending on the situation, which may cause an increase in coating cost. Further, although it has a heat-proof effect after being applied straight, it deteriorates as the surface becomes dirty, and there is also a problem that heat absorption is increased. Therefore, it is strongly desired to develop a technique that relatively inexpensively reduces the indoor temperature of a building at a low cost without adversely affecting the performance without environmental impact. Preventing buildings from lowering the temperature of the solar heat and lowering the indoor temperature is related to the reduction in power consumption, and can actively contribute to preventing global warming. Furthermore, in the case of a roof made of metal, in the case of rain, rain falls directly on the roof surface and the rain sounds loud, and the sound of rain sounds inside the house, which adversely affects the indoor environment. Therefore, in the area of frequent underground heavy rain 2049-8944-PF 6 200839071 % domain, it is hoped that even if it rains, the indoor rain will be small, and the indoor work can be carried out quietly. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a roofing sheet for suppressing the temperature rise of a roof or to naturally cool it, and to cover rain or the like, and to lay the roof with a masking sheet. Or shot on the roof that has been made, the roof itself is protected by the direct sunlight of the sun in a simple configuration, and the top structure of the roof (indoor) can be economically and effectively prevented by natural cooling. Further, in order to provide a roof that can greatly suppress the soundproofing effect of the sound propagating into the room when the current heavy rain is provided. SUMMARY OF THE INVENTION The present invention relates to a shielding sheet for a roof, and the above object of the present invention is to a sheet having a heat-proof property and a shielding property of rain and light, and a perforation hole having a plurality of diameters of 80 to 150 mm is arranged by the above The opening ratio of the entire penetration hole is 3 to 8% for the sheet, and the thickness is 〇 2 to 2 · 〇 mm, and the perforation is provided in the peripheral portion of the sheet as needed, or the sheet is Polyethylene resin can be achieved more efficiently. Moreover, the present invention relates to a roof, and the above object of the present invention is to a sheet having a heat-proof property and a rain or light shielding property, and a plurality of penetration holes having a plurality of diameters of 80 to 150 mm are arranged by the through-holes. The opening ratio is 3 to 8% for the sheet, and the thickness of the sheet is 〇·2~2· 屋顶. The roofing sheet is laid by a metal buckle with a space of 50 to 9 〇 and then laid on the roof. And the above-mentioned folding plate is used as the seam type folding plate, or the folding plate is overlapped by the 2049-8944-PF 7 200839071 type folding plate, or the above-mentioned metal buckle and the top surface of the above-mentioned seam type folding plate are convex The fitting of the upper part can be effectively achieved. [Embodiment] In the present invention, a sheet having a heat-proof property (characteristic of reflecting heat without absorption) and shielding characteristics of rain and light is provided with a penetration hole having a plurality of diameters of 80 to 150 mm, penetrating The opening ratio of the entire hole is laid or stretched on the roof with a space of about 3 to 8% of the roof covering sheet' (approximately 50 to 90 mm). The roofing sheet is excellent in durability and heat resistance, and shields sunlight or rain, by the reflection of the roof mask itself, and the airflow naturally generated by the space (gap) between the roof panel and the roof surface. The heat dissipation (cooling) suppresses the temperature rise due to direct sunlight and prevents temperature rise due to direct sunlight. Moreover, even if it rains, most of the rain will reach the roof surface after colliding with the shielding sheet, and most of the rain will be covered by the roof with the shielding sheet. Therefore, the rain of the roof can be greatly suppressed. Since the roof covering sheets can be easily laid or laid on existing metal roofs (tile bars or flaps) directly or via metal buckles, it is not necessary to extensively remodel and rebuild the finished roof, which is very inexpensive. Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a plan view of a roofing sheet 1 according to the present invention, and a sheet of the roofing sheet 10 is made of a polyethylene resin having a heat-proof property and having a property of shielding rain or light (polyethylene 92·〇~ 97· 〇% by weight, organic-based additives such as amines or phenols, 1% to 3.0% by weight, and pigments '2049-8944-PF 8 200839071 Inorganic additives such as calcium sulphate 〇·5~5·G% by weight) It is formed into a rectangular sheet shape having a width of about 3 to 8 m, a length (depth) of about L5 to 6 m, and a thickness of about 2.2 to 2 〇 (preferably 〇·4〇·8_). Then, in a comprehensive manner of the roof covering sheet 1 , a circular through hole u having a plurality of diameters of about 8 〇 15 15 (preferably 10 0 to 120 mm) is regularly arranged at a predetermined pitch (lattice shape). A perforated hole 12 made of brass for laying or being laid on the roof is provided at a predetermined distance from the peripheral portion of the roof covering sheet 1 . The total aperture ratio of the entire through-hole 11 to the roof covering sheet 10 is preferably about 38%, preferably 4 to 6%. The aperture ratio of the entire through-hole 11 is determined by the diameter and number of the penetration holes 11, and the heat-reflecting fruit of the roof shielding sheet 1 and the roofing sheet 1 and the roof surface are used. The space generated by the natural cooling relationship, the aperture ratio is about 3 to 8%, preferably 4~. When the aperture ratio is less than 3%, the natural cooling by the air flow is inhibited, and the aperture ratio is more than 8%, the heat reflection effect is reduced, and the light and rain shielding effect is reduced. Further, the through hole u of the roofing mask 10 of the present example is circular, but it may be a rectangle, a triangle or a polygon as long as the opening ratio is 3 to 8%. In addition, the material for the roofing sheet 1 is preferably the above-mentioned polyethylene resin, and various fabric sheets, vinyl sheets, rubber sheets, and the like can be used as long as they have heat-proof properties, light resistance, heat resistance, and durability. Sex, can cover the rain, can withstand wind and rain, snow and other materials. Furthermore, the eyelet 12 is a fingerboard that is fixed to a metal roof, and the seam type flap can be fixed by a locking screw or a bolt or a nut by using the eyelet 12, and the overlapping end is folded. It is not necessarily required because it is used by a fixing member such as a corner member to hold 2049-8944-PF 9 200839071. Moreover, even if it is not an eyelet, it is sufficient to lock the screw or the hole to which the bolt and the nut are fixed. In the present invention, such a roof covering sheet 1 is laid or laid on a metal roof made of, for example, a roof formed of a seam-type flap or an overlap type flap, or a roof in which the tile is arranged. The height of the roof surface of the seam-type flap or the overlap type flap is about 50 to 90, which forms a space for airflow with the roof mask sheet ι. If the height of the tile is low, it can be laid or stretched through a metal buckle with a height to form a space (gap) of about 50 to 90 mm between the roof surfaces. The inclination of the metal roof is usually 30 degrees or less above the twist. Then, when the roofing cover sheet 10 is laid or laid, the end portion of the reinforcement end portion may be a reinforcing portion (edge portion) of a reinforcing material such as a polyethylene rope. 0mm。 Preferably, the diameter of the end of the reinforcing material is about 2.0~6. 〇mm, preferably 3.0~5. 0mm. The rope as the end reinforcing material is generally polypropylene, and it is preferable that the polyethylene having the same relationship as the roof covering sheet 10 is recovered. Fig. 2 is a view showing an example in which a slat roof covering sheet 1 is laid or laid on a metal roof 20, and Fig. 2(a)a is a plan view, Fig. 2(B) is a front view (detailed Fig. 3), Fig. 2 (C) is a side view (detailed in Figure 4). The roof 2 is formed of a plurality of sheet-folding plates 21 of a seam type or a superposition type, and steel tight frames 24A and 24B are provided on the upper and lower portions of the roof 20 so that the end faces of the roof 2〇 are provided to the roof covering sheets 10 The distance L1 is equal to or greater than 50 〇 mm. The spacing distance L1' is set because the heat is dissipated by the airflow more than the coverage of the roof. It is effective to cover the roof area with the cover sheet 10 by 7 〇 to 9 〇%.

In this case, in the case of the seam-type flap, when the flap 12' is used to overlap the flap, the roofing mask having no perforation i 2 is used, and the end portion is folded and fixed by a fixing member such as an angular member. The details will be described later. In addition, FIG. 5 shows an example in which four roof covering sheets ι 〇Α 10C are laid or laid on the metal roof 20, and FIG. 5(A) is a plan view, FIG. 5(B) is a front view, and FIG.

For the round head screw inspection 222, the two portions of the bolt 222 are locked and fixed by the nuts 223A and (10), and the roof shielding sheet 10 is used for the case of the house 71 2G. A groove 224 is disposed at the bottom of the metal buckle 221, and the groove 224 is comminuted with the rail-shaped convex portion 2U existing at the top of the joint type (4) 2U, and the metal buckle is supported by the groove 224 and the convex portion 2 ιι The 221 is fixed to the seam type flap 2U. By using the metal buckle 221 having a height, a space for generating airflow is formed between the roof shielding sheet 1〇 and the seam-type flap 2ia (the height is about 50 to 90 mn. Further, FIG. 7 is similarly shown The structural example of the roof sheet covering sheet 1A is attached to the top of the seam-type flap 21A. The groove 226 provided at the bottom of the trapezoidal pyramid-shaped metal buckle 225 is formed in the seam-type flap 21. The rail-shaped protrusion 211 of the top is fitted, and the metal buckle 2 is fixed to the seam-type flap 21A. The hexagonal nut 227 for locking is attached to the lower part of the metal buckle 225, and the hexagonal screw is used. The cap 227 is locked by both sides, and the metal buckle 225 can be more firmly fixed to the seam-type flap. Then, the hole at the top of the metal buckle 221 and the eyelet 12 of the roof cover sheet 1 pass through the corner root. The round head bolt 222 is fixed to both ends of the bolt 222 by nuts 223 and 223, and the roof cover sheet 1 is attached to the seam type flap 21. By using the metal buckle 225 having a height, A space for generating airflow is formed between the seam-type flaps 21 of the roof (the height of about 50 to 90 positions) Next, the roof cover sheet 1 〇 is attached to the overlap type flap 21B. 204 9-8 94 4 - PF 12 200839071 is illustrated as shown in Figs. 8 to 10. The top of the overlap type flap 21B does not exist. In the case of the projection portion 211 of the seam-type flap 21A, the construction method is different from that of the seam-type flap 21A. Fig. 8 is a view in which the roof shielding sheet 1 is attached to the X portion (middle portion) of Fig. 2 . For example, first, a rectangular parallelepiped metal buckle 23〇 is fixed to the top of the overlap type folding plate 21B by bolts and nuts 231. Then, the roof covering sheet 10 is laid on the metal buckle 230, and the roof is fixed by screws 232. The cover sheet 10 is used. The roof cover sheet 10 is attached to the overlap type flap 21B in this order at a predetermined pitch. At this time, since the metal buckle 230 having a height is used, it is used for the roof. A space for generating airflow (having a height of about 5 〇 to 9 〇 mm) is formed between the shielding sheet 1 〇 and the overlapping folding plate 21B. Fig. 9 and Fig. 1 〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇丨〇 For example, the end portion is first fixed at the top of the overlap type folding plate 21B with a bolt and a nut 234. Rectangular tubular metal buckle 233. The reason why the metal buckle body 233 - the end opening is inclined, is to facilitate the tool from the top (four) bolts, nuts 234, or both ends have a tilt, or (four) flat The metal buckle 233 is fixed on the top of the overlapping type plate 21β, and the tubular metal buckle 235 and the tubular angle material _ purely arranged, and the metal buckle 235 and the tubular angle material are screwed and fixed on the metal buckle 233, and the metal dial 4 qqe: ”5 and the tubular angle material for the roofing cover sheet 10.

As described above, the roofing cover sheet 10 of the present invention is attached to the flap or laid on the roof, as shown in the schematic view of Fig. 11, the heat of the sun is reflected on the surface of the roof covering sheet 10, and Airflow (wind) is generated by the space formed between the penetration hole 11 and the roof panel 1 折 and the flap to ventilate the air. Therefore, the heat shielding effect by the roof covering sheet 10 is extremely large. In other words, since the thickness of the roof covering sheet 10 is 0·2 to 2.0 mm, the heat storage amount of the sheet itself can be suppressed, and the roof covering sheet is mounted by a metal buckle from the roof surface by about 50 to 90 mm. Therefore, the amount of heat transfer to the roof can be suppressed. Further, the roof is shielded by a heat shielding and cooling by a shield sheet or a roof, and the temperature rise is suppressed. Fig. 12(A) shows the previous roof of the roof covering sheet which is not laid or laid, and heat from the sun is conducted to the room and the room temperature rises. In this case, if the roofing mask 1 is not laid on the roof or the roof covering sheet 1 is used, the heat from the sun is shot by the roof covering sheet 1 〇 & It can suppress or prevent the rise of indoor temperature. For the black roof, the silver roof, and the white roof, a lamp with a heat source temperature of about 75 ° C was used, and after the lamp was turned on for about 5 minutes from the lamp for about 5 minutes, the temperature rise was measured as the difference under T + ^ ^ . The black roof is 6 2 · 9 °C, and the silver roof is unshielded. The case is 40. The silver roof is covered with 33.5C and the white roof is 4l rc. 13 is an experimental data showing the temperature control effect of the present invention.

In addition, in the case where the metal roof is used as the roof, the case where the joint type flap and the overlap type flap are laid or the roof covering sheet is used is described, but it is not limited to the roofer as long as it is on the roof. It is sufficient to form a suitable space between the roofing sheet and the shielding sheet for the roof. In particular, the effect on the metal roof is large, but it is not limited to the metal 2049-8944-PF 16 200839071 roofer. The above description of the embodiments of the present invention is intended to be a modification of the present invention. The cover sheet for a roof of the present invention has a sheet which is formed in a regular arrangement or in a loosely formed manner to have a heat-proof property and has a property of shielding light and rain, and can be easily laid or laid on a metal roof, durability or It has excellent heat resistance, and it is only possible to set the space to be laid or to be placed on the roof. It can generate heat dissipation by the reflection of the sheet and the naturally generated airflow, which can suppress the temperature rise and effectively prevent the temperature rise due to direct sunlight. In addition, the roof of the roof covering sheet is laid or laid, and there is a space between the roof top and the roof covering sheet, and the airflow is naturally formed by the penetration hole provided in the roof covering sheet, which can alleviate or suppress the cause. The direct flow of heat prevents direct sunlight from illuminating the roof and making the roof hot. The wind (air) will be formed in the space between the roof top and the roof covering sheet by the through-holes to change the air to generate a cooling roof, suppressing the lifting of the roof covering sheet, preventing fluctuations and making the roof The shielding sheet is broken, and there is also an effect of draining rainwater or the like accumulated in the roof covering sheet from the penetration hole. When the wind blows, the flow rate above the sheet is faster than the bottom of the sheet, and the lift due to the air flow. However, since the hole is opened at 3 to 8 ° / ◦ on the sheet, the lift can be offset, and the floating or fluctuation of the sheet can be suppressed. The effects of the present invention are not artificially or mechanically performed, but are carried out naturally, so that there is no need for running costs and economic effects. Furthermore, the roof of the present invention is used as a roofing mask for the use of a combustible material of 204 9-8944-PF 17 200839071 polyethylene resin, but the thickness is 〇·2~2·0 mm, so when laying or laying on the roof of the degree The heat transfer function of the film is attenuated or disappeared, which can suppress the temperature rise of the sheet. Therefore, it also has the function of incombustible materials, and the 35-foot building reference method.
