ROOF STRUCTURE CAPABLE OF INCREASING AND DECREASING FRICTION WITH SNOW ACCUMULATION
To make snow accumulation on a roof slip down at an optional timing.SOLUTION: Snow accumulates on a roof where a plurality of roof materials are arranged, in which the roof material is hardly embrittled, can be deformed, and is curved outwardly or inflated by gas. When making the snow accumulation slip down, by moving and deforming a part of the roof materials, the roof material being in close contact with the snow accumulation is peeled. At that time, a valley portion of the roof material in which contact resistance with the roof material due to snow pressure of snow accumulation is large is widened, a space is formed and contact resistance with the snow accumulation is further reduced simultaneously. Thus, the snow accumulation on the roof slips down by its own weight.SELECTED DRAWING: Figure 1
【課題】屋根上の積雪を任意のタイミングで滑落させる。【解決手段】低温でも脆化しにくい、変形可能な、外側に湾曲または気体により膨張させた屋根部材を複数並べた屋根に積雪させ、その積雪を滑落させたい時に前記屋根部材の一部を移動してに変形させる事で、積雪と密着していた屋根部材は剥離する。この時、同時に積雪の雪圧による屋根部材接触抵抗が大きかった前記屋根部材の谷間部分が広がり、空間が出来て積雪との接触抵抗が更に減少するので前記屋根上の積雪は自重により滑落する。【選択図】図１
