To improve the utilization of the volume of the material in the middle of the cross-section of load carrying construction, for example, laminated wooden beams, and to increase the stiffness and bending strength, combinations of structural components, such as laminated wooden beams and lamells, which are curved in presses while the components are assembled, may be used. After being removed from the presses, planned and permanent pre-stresses will be introduced into the entire construction units. Reinforcing components, such as steel, can also be used in combination with the above described methods of construction. |
