    摘要： The present invention is a saw guiding device for guiding a power saw when cutting a workpiece in the form of either a flat board or an I-beam. The saw guiding device comprises a base member which is to be disposed across end caps of an I-beam. A straight saw guiding surface of the base member is configured such that a power saw can be engaged therewith and slidably moved therealong to thereby guide the power saw in a straight line as it cuts the I-beam. The base member includes an upwardly facing saw supporting surface disposed adjacent the straight saw guiding surface. The upwardly facing saw supporting surface is constructed and arranged to support the power saw as it is engaged with and slidably moved along the straight saw guiding surface between the end caps of the I-beam. The base member has a workpiece edge engaging structure extending downwardly therefrom. A movable workpiece edge engaging structure is constructed and arranged to be moved through a range of operative positions. The movable workpiece engaging structure is fixable at various locations within the operative range. Both the workpiece edge engaging structure and the movable workpiece edge engaging structure are simultaneously engageable with one edge of an I-beam end cap when the base member is disposed across the end caps and the workpiece engaging structure is fixed at one of the various locations of the range of operative positions to set a desired cutting angle at which the straight saw guiding surface is disposed.

    摘要翻译： 本发明是用于在以平板或工字钢的形式切割工件时引导动力锯的锯引导装置。 锯条引导装置包括一个基本构件，该基座件将设置成横跨工字梁的端盖。 基部构件的直线导引面被构造成使得动力锯可以与其接合并且可滑动地沿其移动，从而在切割工字梁时引导电锯在直线上。 基部构件包括邻近直锯导向表面设置的面向上的锯支撑表面。 向上的锯支撑表面被构造和布置成支撑电锯，因为它与I型梁的端盖之间的直锯导向表面接合并可滑动地移动。 基部构件具有从其向下延伸的工件边缘接合结构。 可移动的工件边缘接合结构被构造和布置成移动通过一定范围的操作位置。 可动工件接合结构可固定在工作范围内的各种位置。 当基部构件跨过端盖布置时，工件边缘接合结构和可移动工件边缘接合结构都可同时与I型端盖的一个边缘接合，并且工件接合结构固定在 设置直锯引导表面所期望的切割角度的操作位置的范围。
