    • A venting device (10) comprising an annular wall (11), an annular flange (14) connected to the annular wall (11) and extending away from the annular wall (11) in the radial direction, and a cup-shaped member (16) connected to the annular wall (11). The cup-shaped member (16) defines a cavity with a peripheral edge (19) facing away from the flange (14) in the axial direction. The cup-shaped member (16) having a venting hole (20) allowing air to pass through the venting hole (20). the cup-shaped member (16) is invertible so that when inverted the peripheral edge (19) faces towards the flange (14) and so that a sheet material (100) such as an underroof can be accommodated between the flange (14) and the peripheral edge (19) with the peripheral edge (19) in sealing contact with the sheet material (100).
    • 一种通风装置(10),包括环形壁(11),连接到环形壁(11)并沿径向远离环形壁(11)延伸的环形凸缘(14),以及杯状构件 16)连接到环形壁(11)。 杯状构件(16)限定具有沿轴向背向凸缘(14)的外围边缘(19)的空腔。 杯形构件(16)具有允许空气穿过通气孔(20)的通气孔(20)。 杯形构件16是可翻转的,使得当翻转时,周边边缘19朝向凸缘14并且使得诸如底板的片材100可容纳在凸缘14和14之间, 所述外围边缘(19)的外围边缘(19)与所述片材(100)密封接触。
