Profile arrangement with connecting elemet for sectional girders

Abstract

A profile arrangement ( 11 ) has two coaxially serially disposed sectional girders ( 12 ) and having a connecting element ( 16 ), the connecting element ( 16 ) having a value of its section modulus (Wy 1 ) that differs maximally by 10% from the value of the corresponding section modulus (Wy 2 ) of the sectional girders ( 12 ).

1 . A profile arrangement comprising:
 at least two coaxially serially disposed sectional girders; and   a connecting element for joining the sectional girders, the connecting element having a value of its section modulus differing maximally by 10% from a further value of the corresponding section modulus of the sectional girders.   
     
     
         2 . The profile arrangement as recited in  claim 1  wherein the difference in the values of the corresponding section moduli is maximally 5%. 
     
     
         3 . The profile arrangement as recited in  claim 1  wherein the connecting element is a peripherally closed, hollow profile section. 
     
     
         4 . The profile arrangement as recited in  claim 3  wherein material accumulations are provided at mutually opposing sides of the hollow profile section extending in parallel to a corresponding resistance axis. 
     
     
         5 . The profile arrangement as recited in  claim 1  wherein the connecting element is introduced into end regions of the sectional girders to join the sectional girders, and the insertion depth of the connecting element into one of the sectional girders is 50 to 500 mm. 
     
     
         6 . The profile arrangement as recited in  claim 5  wherein the insertion depth of the connecting element into the one of the sectional girders is 75 to 200 mm.
