BEST MODE FOR CARRYING OUT THE INVENTION

The present invention could protect roofs themselves from direct sunlight with a simple configuration, and also could prevent the roofs from becoming high temperature by positively cooling them.

Embodiment-1

Embodiments of the present invention will be described based on the drawings.
FIG. 1 is a plan view of a roof showing one embodiment of the present invention, and FIGS. 2 and 3 are principal part sectional views thereof, wherein it is configured that the planar base material 2 is arranged on a roof 1. It is effective to cover about 70 to 90% of the roof 1 with the planar base material 2.
The roof 1 in the drawings is a low profile standing seam metal roofing roof of a flat roof, being removably attached with a bolt and nut 13 using an angle 6 of a snow stopper 5 which is attached to a cap 4 of a knot of a metal roofing board 3, and attachment holes 7 of a planar base material 2, and the planar base material 2 is arranged on the roof 1 while loosing from the surface of the roof 1 and providing a clearance 8 (about 50-90 mm) therebetween. The attachment holes 7 are disposed to the peripheral edge portion of the planar base material 2 at a predetermined pitch.
The planar base material 2 is a thin board-like material or a sheet-like material, the material of which may be any kind of materials, such as wood, resin, metal, or cloth, and gaps 9 penetrated through a back and front sides are formed therein.
The gaps 9 which penetrate through the back and front sides may be formed linearly or geometrically to be scattered regularly or arbitrarily. In a case that the gaps 9 are through holes, an opening rate of the overall through holes to the planar base material 2 is set to about 3 to 8% and preferably 4 to 6%.
As a net structure, a textile net or a knitted net, such as a resin net, a synthetic fiber net, a mesh cloth, a screen mesh, a bolting cloth, a wire net, or a net punched holes uniformly or the like, are provided with the gaps 9, so that they can be used for the planar base material 2 as they are.
Further, a tape-like material of thin width is woven or knitted to form the gaps 9, or a configuration arranging a stick material or a string material within a frame in the shape of barred lattice can also provide the streaky gaps 9, so that they can be used for the planar base material 2 as they are.
As the sheet, a material which has tensile strength, such as various textile cloth, a vinyl cloth, a rubber material is desirable, and a material called a shade sheet variously processed, such as light-proof, heat resistance, waterproofing, or a cold gauze may be used. For example, the thickness of the sheet is about 0.2-2.0 mm, preferably 0.4-0.8 mm.
As the board material, although a single board of the various materials and a plyboard can be used without any limitations, a board as thin as possible is preferable. For example, the thickness of the board material is about 2.0-20.0 mm.
In addition, a corrugated board such as polystyrene or the like, a thin board made of resin with a heat insulation function, or a single board and a plyboard with a heat insulating layer on the surface are also desirable.
Moreover, a shape and a size of the through holes 9 formed in the sheet or the board material may adopt arbitrary one, and scattering of the through holes is designed appropriately based on a relation between an increase in roof temperature by sunlight passing therethrough and a ventilation circulation. For example, the diameter of the through holes 9 is about 80-150 mm (preferably 100-120 mm) in a case of circular holes (refer to FIG. 4).
Since the roof 1 is blocked by the planar base material 2 without sunlight hitting directly, the temperature rise of the roof 1 itself can be prevented, even when the net planar base material is used, it has a block function of sunlight.
Subsequently, since the space of the clearance 8 is formed between the roof 1 and the planar base material 2, and the planar base material 2 is provided with the gaps 9 and 9 . . . , air goes in and out and circulates from the ends and the gaps 9 of the planar base material 2 of the roof 1, so that the air in the space of the clearance 8 is aerated to thereby prevent the temperature in the space from becoming high, and the air cooling function of the roof 1 itself is also performed, and the loose of the planar base material 2 by the wind or the like can also be prevented.

Embodiment-2

The roof 1 is a flat roof which is gently inclined in a direction from the top to the bottom and is formed of a roof deck 10 in the drawing, and concave streaks (valley parts) 11 and convex streaks (mountain parts) 12 of the roof deck 10 are also arranged in the top to bottom direction along with an inclination in the drawing.
The roof 1 may have concave-convex streaks formed thereon, so that means and configurations for forming the streak are not limited to a kind of roof deck, and a kind of roof is not considered, either.
The planar base material is in removable fixed and arranged with the bolts and nuts 13 provided in a circumferential end of the roof 1 corresponding to the attachment holes 7 and 7 . . . provided in the circumference.
Moreover, the gaps 9 and 9 . . . exist in the planar base material 2 on a ventilation flue 14 formed of the concave streak 11 of the roof 1 and the arranged planar base material 2.
Hence, since air in the ventilation flue 14 goes in and out and circulates from the end and gaps of the concave streak of the planar base material 2, the air in the ventilation flue 14 is ventilated to be able to prevent the temperature from becoming high, and the air cooling function of the concave streak 11 of the roof 1 which forms the ventilation flue 14 or the planar base material 2 is also performed, and the loose of the planar base material 2 by the wind or the like can be also prevented.

Embodiment-3

FIG. 7 is a plan view showing another embodiment, wherein a plurality of the planar base materials 2 and 2 . . . are mutually arranged on a plane-like roof 1 with an interval 15, and air can go in and out and circulate from the portion with the interval 15 to the ventilation flues 14. For example, the interval 15 is about 10-500 mm.

Embodiment-4

FIG. 8 is a plan view showing another embodiment, wherein the planar base material 2 is arranged from the inside except the end 16 in the direction of the concave- convex streaks 11, 12 of the roof 1, so that air can easily go into the ventilation flues 14 from the end 16 which the planar base material 2 is not arranged thereon.
The above description shows one embodiment of the present invention, and the mere design change from which the same effect can be obtained and the modifications by means of common practice are included in the embodiments of the present invention.
