Abstract
An elongate construction element according to the invention is made of plastic which has a first, low modulus of elasticity, and a lamination of a material which has a second, significantly higher modulus of elasticity inside the construction element. The construction element has at least one system plane along which the construction element has essentially homogeneous characteristics and is essentially homogeneously constructed. The lamination lies on both sides of the system plane and crosses through the latter at least at one point. The cross-sectional areas of the lamination and the plastic are inversely proportional functions of the effective moduli of elasticity of the plastic and of the lamination so that the flexural rigidities of the cross-sectional areas are essentially equal. The lamination is at least essentially continuous.

An elongate construction element, made of plastic which has a first, low modulus of elasticity, and having a lamination of a material which has a second, significantly higher modulus of elasticity inside the construction element, and at least one system plane associated with the construction element, along which plane the construction element has essentially homogeneous characteristics and is essentially homogeneously constructed,
- comprising the improvement wherein:
- a) the lamination lies on both sides of the system plane and crosses through the latter at least at one point;
- b) the cross-sectional areas of the lamination and the plastic are inversely proportional functions of the effective moduli of elasticity of the plastic and of the lamination so that the flexural rigidities of the cross-sectional areas are essentially equal and
- c) the lamination is at least essentially continuous.
