ABSTRACT:
The structural combination flange gauge of my invention for laying out the flange of structural steel beams and girders with great ease, speed, and accuracy comprises a base member with tripod, or three point, supporting means for the support thereof upon the web of the structure steel beam to be laid out. An inverted generally U-shaped stem bar is adjustably secured to the base member, which stem bar includes inner and outer leg portions connected by an intermediate portion adapted to extend over the flange of the beam upon which the base member is supported. A gauge member for use in marking of the beam flange is adjustably secured to the outer leg portion of the stem bar, which gauge member is generally E-shaped and includes a straight edge section extending parallel with the outer leg portion of the stem bar and a plurality of parallel arm sections extending at right angles from one side of the straight edge section. The upper and lower ends of the straight edge section extend above and below the respective upper and lower-most parallel arm sections of the gauge member to facilitate cross marking on the beam flange. The gauge member arms are uniformly spaced and are of a uniform width. Also, colinear line sections are formed on the parallel arm sections parallel with the straight edge section for use in angular marking of the beam flange. Axially aligned through holes are formed in the parallel arm sections of the gauge member through which the outer leg portion of the stem bar extends, and releaseable locking means such as a thumb screw releaseably secure the gauge member to said outer leg portion. In addition, an adjustable stop means is releaseably secured to the stem bar and which is adapted for abutment with the gauge member for establishing the position of the gauge member along the stem bar. The adjustable connection between the stem bar and base member includes a first pin pivoting the stem bar to the base member for pivotal movement of the stem bar about a longitudinal axis parallel to a plane passing through the feet of the tripod supporting means for angular layout of the flange. A pointer and associated dial means carried by the stem bar and base member provide a visual indication of the angular setting of the gauge member. The adjustable connection between the stem bar and base member includes a second pivot pin for pivotal support of the stem bar about a transverse axis also parallel to the plane passing through the feet of the tripod supporting means for tilting the gauge member in a forward or rearward direction for use on beams with twisted flanges.
