Sectioning scheme applied to two- or four-foot cross tee members associated with a ceiling grid system and accounting for an offset existing between an associated end of a cross tee and a center point of the main tee measured to an oppositely positioned wall angle

Abstract

A measurement scheme applied to a cross tee member accounting for an offset between the tee and a cross-sectional center point of a main tee measured to a wall angle. The cross tee exhibits an overall length with first and second opposite lip supporting edges. A cross section of the cross tee including a tile support and a web extending in substantially perpendicular fashion from a midpoint of the support. First and second connector clips extend from first and second edges of the cross tee. An overall rated length of the cross tee corresponds to a lineal distance measured between center line locations associated with inserting portions of the connector clips. An indicia marking scheme is applied at linear extending intervals along the cross tee, an outermost selected indicia marking establishing a first specified lineal distance with a centerline location of a selected one of the connector clips. The marking establishes a second specified lineal distance with a further selected marking to determine a sectionable length of the cross tee equaling the dimensional offset existing between the main tee and the wall angle.

1 . A measurement scheme applied to a cross tee member and specifically tailored to account for a dimensional offset existing between the cross tee and a center point of a cross sectional location of a main tee measured to a wall angle, comprising: 
 the cross tee having an overall length exhibiting first and second opposite and lip supporting edges, a cross section of the cross tee including a tile support and a web extending in substantially perpendicular fashion from a midpoint of said support;    first and second connector clips extending from said cross tree approximate said first and second edges, an overall rated length of the cross tee corresponding to a lineal distance measured between center line locations associated with inserting portions of said connector clips; and    an indicia marking scheme applied at linear extending intervals along the cross tee, an outermost selected indicia marking establishing a first specified lineal distance with a centerline location of a selected one of said connector clips, said marking establishing a second specified lineal distance with a further selected marking to determine a sectionable length of the cross tee equaling the dimensional offset existing between the main tee and the wall angle.    
   
   
       2 . The scheme as described in  claim 1 , the cross tee exhibiting a specified shape and size, an outermost one of said indicia markings measuring one (1″) inch from a centerline location associated with said associated connector clip.  
   
   
       3 . The scheme as described in  claim 2 , said indicia markings extending at intervals of at least every three (3″) inches from a center point of said rated length and along the cross tee.  
   
   
       4 . The scheme as described in  claim 2 , said indicia markings extending at intervals of at least every (1″) inch from a center point of said rated length and along the cross tee.  
   
   
       5 . The scheme as described in  claim 1 , the cross tee having a specified shape and size and with a rated distance of forty eight (48″) inches.  
   
   
       6 . The scheme as described in  claim 1 , said cross tee having a specified shape and size, and with a rated distance of twenty-four (24″) inches.
