Abstract (en)
[origin: WO2012044173A1] Pre-stressed beams where two outer elements (10-12) being symmetrical or near symmetrical along the neutral axis of the cross-section of the beam, are joined together by means of a center element (11) after bending and mutual sliding of the element surfaces. The outer elements (10, 12) are held together by means of the shear transmitting center element (11) arranged for mechanical and/ or chemical transmission of forces. A method for the manufacture of such beams is also provided.
