Definitions

  • the present invention relates to a roof blocking sheet for effectively reducing transmission of solar heat as well as blocking sound of rain and the like by being laid or stretched to a roof a building and to a roof structural view using the roof blocking sheet.
  • the present invention relates to a roof blocking sheet capable of reducing a room temperature by preventing a roof forming member from being heated to a high temperature by direct sunlight and optimally acting as a countermeasure for energy saving and global warming prevention as well as reducing sound of rain and a roof using the roof blocking sheet.
  • the roofs of a house, a building, a factory, a warehouse or the like are conventionally impinged with direct sunlight, they are heated to a high temperature by the direct sunlight, and thus rooms are also heated to a high temperature by the heat of the sunlight transmitted thereinto.
  • the temperatures of metal roofs such as a steel roof deck, a galvanized iron roof and the like are outstandingly increased.
  • a countermeasure for blocking the heat transmitted from a roof by improving the ventilation in the space under the roof is conventionally employed.
  • a heat insulation structure is employed to a roof itself to prevent an increase of room temperature by blocking the heat from the roof.
  • the conventional method of improving ventilation in the space under the roof has a problem in that the structure of a building is made complex and a construction cost becomes expensive. Further, when a fan and the like are used for ventilation, a problem arises in that a running cost is required and a maintenance is necessary.
  • the method of providing the roof with the heat insulation structure is disadvantageous in that a roof structure itself is made complex and a construction cost is increased by a heat insulating material built in the roof. Further, there is also a problem in that when an existing roof is provided with the heat insulation structure, a construction cost increases because the overall roof must be rebuilt.
  • any of the above methods has a problem in structure when it is applied to, for example, a factory, a large store building, a warehouse, a garage, and the like, and in particular, when it is applied to a metal roof making use of a low profile standing seam and a steel roof deck, the metal roof is outstandingly heated by direct sunlight and a room is adversely affected by the heat.
  • the effect of the methods is limited.
  • An object of the present invention which was made in view of the above circumstances, is to provide a roof blocking sheet for suppressing an increase of temperature of a roof or naturally cooling the roof as well as blocking the rain and the like and to provide a roof structure for protecting an existing roof itself from direct sunlight by a simple arrangement by laying or stretching the roof blocking sheet to the existing roof as well as preventing the roof (room) from being heated to a high temperature by naturally cooling it economically as well as effectively.
  • an object of the present invention is to provide a roof having a noise insulation effect for greatly suppressing the transmission of a sound of rain when strong rain falls.
  • the present invention relates to a roof blocking sheet, and the above objects of the present invention can be effectively achieved by that a plurality of through holes with a diameter of 80 to 150 [mm] are disposed to a sheet material having heat blocking characteristics and rain and light blocking characteristics, wherein the opening rate of the overall through holes is set to 3% to 8% and the sheet material has a thickness of 0.2 to 2.0 [mm].
  • the objects can be more effectively achieved by that metal eyelets or holes are formed to an edge surface of the sheet material or that the sheet material comprises polyethylene resin.
  • a roof blocking sheet which comprises a sheet material which has a heat blocking characteristics and rain and a light blocking characteristics and to which a plurality of through holes with a diameter of 80 to 150 [mm] are disposed, is laid or stretched to a steel roof deck through hooks with a space of 50 to 90 [mm], wherein the opening rate of the overall through holes to the sheet material is set to 3% to 8%, and the thickness of the sheet material is set to 0.2 to 2.0 [mm].
  • the steel roof deck is a seam type steel roof deck or a bolted steel roof deck or that the hooks are engaged with the projections of the apexes of the seam type steel roof deck.
  • a roof blocking sheet is laid or stretched to a roof with a space (about 50 to 90 [mm]) defined therebetween.
  • the roof blocking sheet is composed of a sheet material which has a heat block characteristics (characteristics for reflecting heat without absorbing it) and a rain/light blocking characteristics and to which a plurality of through holes with a diameter of 80 to 150 [mm] are formed so that the overall through holes have an opening rate of 3 to 8% to the sheet material.
  • the roof blocking sheet is excellent in durability and a heat resistance as well as blocks sun light and rain and causes a radiating (cooling) action by the reflection of the roof blocking sheet itself and the an airflow naturally generated in the space (gap) between the roof blocking sheet and a roof surface so that the roof blocking sheet can suppress an increase of temperature due to direct sunlight and can effectively prevent an increase of temperature in a room resulting from the direct sunlight.
  • the roof blocking sheet can be simply laid or stretched to an existing metal roof (low profile standing seam and steel roof deck) directly or through hooks at a very low cost because it is not necessary to modify or rebuild the existing roof.
  • FIG. 1 is a plan view of a roof blocking sheet 10 according to the present invention, and a sheet material of the roof blocking sheet 10 is composed of a polyethylene resin (92.0 to 97.0 wt% of polyethylene, 1.0 to 3.0 wt% of an organic additive of amine, phenol or the like, pigment, 0.5 to 5.0 wt% of an inorganic additive of pigment, calcium carbonate or the like) having a heat blocking characteristics and a rain/light blocking characteristics and is formed to a rectangular sheet shape with a lateral width of about 3 to 8 [m], a longitudinal length (depth) of about 1.5 to 6 [m], and a thickness of about 0.2 to 2.0 [mm] (preferably 0.4 to 0.8 [mm]).
  • a polyethylene resin (92.0 to 97.0 wt% of polyethylene, 1.0 to 3.0 wt% of an organic additive of amine, phenol or the like, pigment, 0.5 to 5.0 wt% of an inorganic additive of pigment, calcium carbonate or the like
  • the overall surface of the roof blocking sheet 10 has a plurality of circular through holes 11 with a diameter of about 80 to 150 [mm] (preferably 100 to 120 [mm]) regularly (in a lattice shape) formed thereto at a predetermined pitch, and brass metal eyelets 12 are disposed to the peripheral edge portion of the roof blocking sheet 10 at a predetermined pitch so that they are used when the roof blocking sheet is laid or stretched to a roof.
  • the opening rate of the overall through holes 11 to the roof blocking sheet 10 is set to about 3 to 8% and preferably 4 to 6%. Although the opening rate of the overall through holes 11 to the sheet is determined by the diameter and the number of the through holes 11, it is set to about 3 to 8% and preferably 4 to 6% from the relationship between the heat reflection effect of the roof blocking sheet 10 and natural cooling carried out by an airflow generated through the space between the roof blocking sheet 10a and the roof surface. When the opening rate is less than 3%, the natural cooling carried out by the airflow becomes ostracized, whereas when the opening rate is more than 8%, the heat reflection effect is deteriorated as well as a light/rain blocking effect is also deteriorated.
  • the through holes 11 of the roof blocking sheet 10 are formed to the circular shape, they may be formed to a rectangular shape, a triangular shape, a polygonal shape as long as the opening rate is set to 3 to 8%.
  • the material of the roof blocking sheet 10 is preferably the polyethylene resin, various types of a fabric sheet, a vinyl sheet, a rubber sheet or the like may be also used. That is, any materials may be used as long as they have heat blocking characteristics, light resistance, heat resistance, and durability blocks, and can block rain and withstands wind, rain, snow or the like.
  • the metal eyelets 12 are fixedly attached to a steel roof deck of a metal roof, seam type steel roof deck.
  • a seam type steel roof deck can be fixed with screws or bolts and nuts using the metal eyelets 12.
  • the metal eyelets 12 are not always necessary in a bolted steel roof deck, because it is possible to use the bolted steel roof deck by folding an edge and clamping it by a fixing member such as an angle member and the like. Further, holes may be used in place of the metal eyelets as long as they can be fixed by screws or bolts and nuts.
  • the roof blocking sheet 10 is laid or stretched to an existing metal roof, for example, a roof composed of a seam type steel roof deck and a bolted steel roof deck or to a roof to which low profile standing seams are disposed.
  • the height of the seam type steel roof deck and the bolted steel roof deck from a roof surface is set to about 50 to 90 [mm], by which an airflow space is formed between them and the roof blocking sheet 10.
  • the roof blocking sheet 10 is laid or stretched through high hooks so that a space (gap) of about 50 to 90 [mm] is formed between the roof blocking sheet 10 and a roof surface.
  • a metal roof ordinarily has an inclination of 0° or more to 30° or less.
  • the edge peripheral edge portion
  • the edge reinforcing member has a diameter of about 2.0 to 6.0 [mm] and preferably 3.0 to 5.0 [mm].
  • polypropylene is ordinarily used as the rope of the edge reinforcing member, it is preferable to use the same polyethylene as that used to the roof blocking sheet 10 from a view point of recycle.

  • the roof 20 is composed of a lot of seal type or bolted type steel roof decks 21, steel tight frames 24A and 24B are disposed on the upper and lower portions of the roof 20, and the separated distance L1 from an edge surface portion of the roof 20 to the roof blocking sheet 10 is set to about 500 [mm] or more.
  • a reason why the separated distance L1 is provided resides in that heat is more radiated by an air flow by separating the edge surface portion of the roof from the roof blocking sheet 10 than entirely covered the roof therewith. It is effective to cover about 70 to 90% of a roof area with the roof blocking sheet 10.
  • the roof blocking sheet 10 is fixed to the apexes of the steel roof deck 21 by bolt and nuts (or screws) 23 through hooks 23.

  • a roof blocking sheet 10A1 and a roof blocking sheet 10A2 are an example in which a separated distance L3 therebetween is set to "0".
  • the separated distance L2 between the roof blocking sheets 10A1, 10A2 and the roof blocking sheet 10B, 10C is set to about 0 to 500 [mm]
  • the separated distance L3 between the roof blocking sheet 10B and the roof blocking sheet 10C is set to about 0 to 500 [mm] .
  • roof blocking sheets When a plurality of roof blocking sheets are laid or stretched as in FIG. 5 , they are fixed to the apexes of the steel roof deck 21 by the bolts and nuts (or screws) 23 through the hooks 22.
  • the metal eyelets 12 are used in the seam type steel roof deck likewise, the roof blocking sheet with no metal eyelet 12 is used in the bolted steel roof deck, and the edge portions thereof are folded and fixed using the fixing member such as the angle member and the like.
  • seam type steel roof deck may be fixed by folding the edge portion thereof using the fixing member such as the angle member and the like without using the metal eyelets, the detail of which will be explained next.
  • FIGs. 6A and 6B show an example in which a trapezoidal quadrangular pyramid shaped hook 221 is fixed to the apex of a seam type steel roof deck 21A, a square root/round head bolt 222 is passed through the hole of the apex of the hook 221 and the metal eyelet 12 of the roof blocking sheet 10, and both the ends of the bolt 222 are tightened and fixed with nuts 223A and 223B, thereby the roof blocking sheet 10 is attached to the roof 20.

  • a space (height: about 50 to 90 [mm]) is formed using the tall hook 221 so that a space, in which airflows are generated, is formed between the roof blocking sheet 10 and the seam type steel roof deck 21A.
  • FIGs. 7A and 7B show an example of a structure in which the roof blocking sheet 10 is attached to the apex of the seam type steel roof deck 21A likewise.
  • a groove 226 formed to the bottom of a trapezoidal quadrangular pyramid shaped hook 225 is engaged with the rail-shaped projection 211 formed to the apex of the seam type steel roof deck 21, and the hook 225 is fixed to the seam type steel roof deck 21A.
  • a hexagonal tightening bolt 227 is extended to a lower portion of the hook 225, and the hook 225 can be more strongly fixed to the seam type steel roof deck 21A by tightening the hexagonal bolt 227 from both the sides thereof.
  • the square root/round head bolt 222 is passed through the hole of the apex of the hook 221 and the metal eyelet 12 of the roof blocking sheet 10, and both the end portions of the bolt 222 are tightened and fixed by the nuts 223A and 223B, thereby the roof blocking sheet 10 is attached to the seam type steel roof deck 21A. Since the tall hook 225 is used, a space is formed between the roof blocking sheet 10 and the seam type steel roof deck 21A(50 to 90 [mm]) so that an airflow is generated in the space.
  • FIG. 8 shows an example in which the roof blocking sheet 10 is attached to anX-portion (midportion) of FIG. 2 , and, first, a rectangular parallelepiped hook 230 with a rectangular cross section is fixed to the apex of the bolted steel roof deck 21B by a bolt and nut 231. Then, the roof blocking sheet 10 is placed on the upper surface of the hook 230, and the roof blocking sheet 10 is fixed by a screw 232. The roof blocking sheet 10 is attached to the bolted steel roof deck 21B by sequentially carrying out the above process at a predetermined pitch. Since the tall hook 230 is used, a space (50 to 90 [mm]) is also formed between the roof blocking sheet 10 and the bolted steel roof deck 21B also in this case so that an airflow is generated in the space.
  • a space 50 to 90 [mm]

  • a reason why an end portion of the hook 233 is opened and inclined is to permit the bolt and nut 234 to be easily tightened with a tool from an upper side, and both the end portions of the hook 233 may be inclined or may be made flat.
  • a rectangular parallepiped hook 235 and a pipe shaped square member 236 are further disposed on the hook 233 in abutment therewith, the hook 235 and the square member 236 are fixed on the hook 233 by a bolt and nut, and the like, and the roof blocking sheet 10 is placed on the hook 235 and the square member 236.
  • an angle member 237 with an L-shaped cross section, which is engaged with the square member 236 is abutted against the roof blocking sheet 10, and the roof blocking sheet 10 is clamped between the square member 236 and the angle member 237 and fixed by a screw 238.

Accordingly, an outstanding heat blocking effect can be obtained by the roof blocking sheet 10.
  • the roof blocking sheet 10 has a thin thickness of 0.2 to 2.0 [mm], the amount of heat accumulated in the sheet itself can be suppressed. Further, since the roof blocking sheet 10 is attached spaced apart from the roof surface about 50 to 90 mm and attached by the hook, the amount of heat transmission to the roof can be suppressed. Further, since the roof blocking sheet, the roof and the like are cooled by the heat radiation caused by the airflow, an increase of temperature thereof can be suppressed.
  • FIG. 12A shows a conventional roof to which the roof blocking sheet is not laid or stretched.
  • a room temperature is increased by the solar heat transmitted into a room.
  • the roof blocking sheet 10 is laid or stretched to the roof as shown in FIG. 12B , since solar heat is reflected on the roof blocking sheet 10 and the amount heat entering into the room is reduced, an increase of the room temperature can be suppressed or prevented.

  • the present invention is not limited to the above roof, and it is sufficient to lay or stretch the roof blocking sheet so that an appropriate space is formed between the roof and the roof blocking sheet.
  • the roof blocking sheet is applied to the metal roof, the application thereof is not limited to the metal roof.
  • the roof blocking sheet of the present invention is a sheet formed by regularly disposing or dispersing the through holes thereto and having heat, light, and rain blocking characteristics.
  • the roof blocking sheet can be easily laid or stretched to the metal roof and is excellent in durability and heat resistance.
  • the roof blocking sheet When the roof blocking sheet is laid or stretched to a roof with a space defined therebetween, it causes a radiating action due to the reflection of heat made the sheet and to a naturally generated airflow, thereby an increase of heat can be suppressed so that a temperature can be effectively prevented from being increased by direct sunlight.
  • a roof to which the roof blocking sheet is laid or stretched, has a space between the upper surface of the roof and the roof blocking sheet, a hot airflow made by direct sunlight is eased or suppressed by an airflow naturally formed by the through holes formed to the roof blocking sheet so that the roof can be prevented from being heated to a high temperature by the direct sunlight radiated to the upper surface of the roof.
  • a wind causes an action for cooling the roof by ventilating the space formed between the upper surface of the roof and the roof blocking sheet and by entering into and going out also from the through holes.

  • the present invention Since the operation/working effect of the present invention is achieved neither artificially nor mechanically and is achieved naturally, the present invention has also an economical effect of not requiring a running cost.
  • the roof of the present invention employs the flammable polyethylene resin as the roof blocking sheet, since its thickness is 0.2 to 2.0 [mm], when it is laid or stretched to a roof with an inclination of 0 to 30°, the heat transmission function of the sheet attenuates or disappears to thereby suppress an increase of temperature. As a result, the roof blocking sheet acts as an inflammable material and satisfies the regulation of building standards.
