    • A roof edge fascia or coping cover having an aerodynamic exterior shape mainly comprising a lower face portion, an intermediate face portion, and a top face portion. The lower face portion is either generally vertical, or sloping or curving upwardly and outwardly, forming an angle within 60° to the vertical outer wall surface of a building. The top face portion, of a substantial lateral size, is generally disposed within ±25° from horizontal. The intermediate face portion, having at least one segment of a substantial lateral size sloping or curving upwardly and inwardly, connects the lower and top face portions. Slope changes at a junction between any two adjacent face portions, or adjacent segments thereof, are generally less than or equal to 50°. Through controlling surface slope changes systematically, this invention ensures an aerodynamic roof edge configuration that effectively mitigate airflow separation from the building surface so as to suppress vortex formation and reduce adverse wind actions on a roof construction.
    • 具有主要包括下表面部分,中间面部分和顶面部分的空气动力学外部形状的屋顶边缘面板或应对盖。 下表面部分大致垂直,或向上或向外倾斜或弯曲,与建筑物的垂直外壁表面形成60°以内的角度。 大面积的顶面部分通常设置在与水平面成±25°的范围内。 中间面部分具有向上和向内倾斜或弯曲的基本横向尺寸的至少一个部分,其连接下部和顶部面部。 在任何两个相邻的面部分或其相邻的部分之间的接合处的斜率变化通常小于或等于50°。 通过系统地控制表面坡度变化,本发明确保了一种有效地减轻与建筑物表面的气流分离的空气动力学屋顶边缘结构,以便抑制涡流形成并减少对屋顶结构的不利风力作用。

    • A fascia and soffit member is roll-formed from sheet metal, such as sheet aluminum, so as to have two unitary panels meeting at a juncture. One such panel, a fascia panel, extends vertically and upwardly from the juncture when the member is installed. The other panel, a soffit panel, extends horizontally from the juncture when the member is installed. The soffit panel has a distal portion spaced from the juncture and defining plural, elongate, preferential bending regions, along a selected one of which the distal portion is so as to form a wall flange that extends vertically, either upwardly or downwardly, when said member is installed. Preferably, the distal portion has a series of spaced ridges defining a series of spaced grooves, each ridge defining one of the preferential bending regions and each groove defining another of the preferential bending regions, and the ridges and the grooves collectively have a corrugated profile. In a simplified embodiment, the fascia panel is omitted.
    • 由板状金属(例如铝板)卷成形筋膜和拱顶构件,以便在两个接合处具有两个一体的面板。 一个这样的面板,一个面板,当该组件安装时,它们从接合部垂直和向上延伸。 另一个面板,一个拱形面板,当安装该构件时,从接合处水平延伸。 拱顶面板具有与接合部隔开的远侧部分,并且沿着所选择的一个远侧部分限定多个细长的优先弯曲区域,以形成当所述构件 已安装。 优选地,远侧部分具有限定一系列间隔开的凹槽的一系列间隔开的脊,每个脊限定优先弯曲区域之一,并且每个凹槽限定另一个优先弯曲区域,并且脊部和凹槽共同具有波形轮廓。 在简化的实施例中,省略了面板。
