    摘要： A double or single hung window assembly includes a rectangular main frame formed by a pair of vertical jamb members rigidly connected by a horizontal sill member and a horizontal head member, and each of the members comprises an extrusion of rigid plastics material. The frame members have outer walls for the rough window opening and laterally spaced inner sloping walls, and the inner and outer walls mate at mitered welded corner joints. The jamb members also have inner channel walls for receiving sliding hardware for at least one sash frame formed of extrusions of rigid plastics material. The inner sloping wall of the sill member has an upwardly projecting integral rib which cooperates with a downwardly projecting stop member or rib on the bottom of the sash frame to limit deflection of the sash frame under high negative windloads.

    摘要翻译： 一个双或单悬挂窗组件包括一个矩形主框架，该矩形主框架由一对通过水平门框构件和水平头部构件刚性连接的垂直边框构件形成，并且每个构件包括刚性塑料材料的挤出物。 框架构件具有用于粗视窗开口和横向间隔开的内倾斜壁的外壁，并且内壁和外壁在倾斜的焊接角接头处配合。 侧壁构件还具有内部通道壁，用于接收用于由刚性塑料材料的挤出物形成的至少一个框架框架的滑动硬件。 门槛构件的内倾斜壁具有向上突出的整体肋，其与窗框的底部上的向下突出的止动构件或肋配合，以限制窗框在高负负荷下的偏转。
