Roof

Abstract

The present invention is a roof, wherein a planar base material in which gaps penetrated through back and front sides are formed is arranged on a roof surface with a clearance between the roof and itself. The roof structure has an effect to economically and efficiently prevent the temperature of the roof from becoming high due to shining down of direct sunlight on the upper surface of the roof.

       10 . A planar base material for a roof according to  claim 9 , wherein said thin board-like material is made of wood, resin, metal or cloth, and said gaps are through holes and an opening rate of said through holes to said thin board-like material is set to about 3 to 8%. 
   
   
       11 . A planar base material for a roof according to  claim 9 , wherein said sheet-like material is made of a textile cloth, a vinyl cloth or a rubber material, and said gaps are through holes and an opening rate of said through holes to said sheet-like material is set to about 3 to 8%. 
   
   
       12 . A planar base material for a roof according to  claim 9 , wherein said net structure is made of resin net, synthetic fiber net, a mesh cloth, a screen mesh, a bolting cloth or a wire net. 
   
   
       13 . A roof structure, wherein a planar base material in which gaps penetrated through back and front sides are formed is attached to a roof surface with a clearance between a roof and itself. 
   
   
       14 . A roof structure according to  claim 13 , wherein said clearance is about 50-90 mm. 
   
   
       15 . A roof structure according to  claim 13  or  14 , wherein said planar base material is a thin board-like material, a net structure or a sheet-like material. 
   
   
       16 . A roof structure according to  claim 15 , wherein said thin board-like material is made of wood, resin, metal or cloth, and covers about 70 to 90% of said roof. 
   
   
       17 . A roof structure according to  claim 15 , wherein said sheet-like material is made of a textile cloth, a vinyl cloth or a rubber material, and covers about 70 to 90% of said roof. 
   
   
       18 . A roof structure according to  claim 15 , wherein said net structure is made of resin net, synthetic fiber net, a mesh cloth, a screen mesh, a bolting cloth or a wire net. 
   
   
       19 . A roof structure according to  claim 13 , wherein many concave-convex streaks are formed in a certain direction on a roof, and ventilation flues are formed in spaces between said concave streaks and said planar base material. 
   
   
       20 . A roof structure according to  claim 19 , wherein said spaces are 50-90 mm, respectively. 
   
   
       21 . A roof structure according to  claim 19  or  20 , wherein said planar base material is arranged from an inside except an end thereof in a direction of said concave-convex streaks on said roof. 
   
   
       22 . A roof structure according to  claim 13 , wherein said planar base material has a heat insulation efficiency and has attachment holes disposed to peripheral edge portions at a predetermined pitch, and said planar base material is attaché to said roof surface through said attachment holes. 
   
   
       23 . A roof structure, wherein plural planar base materials in which gaps or through holes penetrated through back and front sides are formed are attached to a roof surface with a clearance between a roof and itself and with mutual intervals. 
   
   
       24 . A roof structure according to  claim 23 , wherein said roof is a steel roof deck or a low profile standing seam. 
   
   
       25 . A roof structure, wherein plural sheet-like materials are mounted on convex streaks of a steel roof deck except for an end portion of a roof in a direction of concave-convex streaks with mutual intervals, ventilation flues are formed between said concave streaks and said sheet-like materials, and plural through holes are provided at said sheet-like materials over said ventilation flues,
 thereby to ventilate air in said ventilation flues from said through holes and to prevent a loose of said sheet-like materials by wind.   
   
   
       26 . A roof structure according to  claim 25 , wherein, an opening rate of said through holes to said sheet-like material is set to about 3 to 8%, preferably 4 to 6%.
