PROBLEM TO BE SOLVED: To provide a waterproof insulation structure having a higher durability and a higher shock resistance.SOLUTION: A waterproof insulation structure 11 comprises an insulation layer 20 disposed on an upper surface 3 of a roof 2, a first waterproof layer 25 disposed on an upper surface 21 of the insulation layer 20, a reinforcement layer 31 disposed on an upper surface 26 of the first waterproof layer 25, a second waterproof layer 50 disposed on an upper surface 43 of the reinforcement layer 31, and a finish layer 55 disposed on an upper surface 51 of the second waterproof layer 50. The reinforcement layer 31 comprises a reinforcement sheet 34 laid on the upper surface 26 of the first waterproof layer 25 and made of fiber material, a third waterproof layer 38 disposed on an upper surface 35 of the reinforcement sheet 34, and silica sand 42 disposed over an upper surface 39 of the third waterproof layer 38. Since the reinforcement layer 31 protects the insulation layer 20, the waterproof insulation structure 11 has a higher durability. In addition, since the reinforcement sheet 34 is disposed over the insulation layer 20 via the first waterproof layer 25, the waterproof insulation structure 11 has a higher shock resistance.SELECTED DRAWING: Figure 1 |
