Abstract
A thermally compensated structural element (1) comprising an upper element ( 2) and a lower element (3). The upper element consists of an angle section with a mainly horizontal part (15) and a mainly vertical part (16). The lower eleme nt (3) is designed with a base part (17) and a vertical part (18). The upper element (2) and the lower element (3) are both connected to connection elements (5, 6, 7, 8, 9) in such a way that thermally induced expansion/contraction is compensated for. The solution comprises further features which will contribute to preventing distortion of the structural element. Structural elements of the above type may be used in a base frame f or covers which are used in thermal processes such as section covers for use in furnaces for calcining of carbon bodies.
Claims (8)
1. A thermally compensated structural element (1) comprising an upper element (2) and one or more lower elements (3, 3', 3"), characterised in that the upper element consists of an angle section with a mainly horizontal part (15) and a mainly vertical part (16) thus having a L- or U- shape, the lower element (3) is designed with a base part (17) and a vertical part (18), thus having a T-shape, whereby the upper element (2) and the lower element (3) are interconnected by means of a first connection element (5) centrally mounted in relation to the extent of each lower element (3, 3', 3"), and further by means of connection elements (6, 7, 8, 9) designed to be able to compensate for mutual movement between the upper element (2) and the lower element (3) in the longitudinal direction of the structural element (1).
2. A thermally compensated structural element in accordance with claim 1, characterised in that the connection elements (5, 6, 7, 8, 9) are plate-shaped and permanently connected, at their upper ends, to the upper element (2) and, at their lower ends, to the lower element (3).
3. A thermally compensated structural element in accordance with claim 1, characterised in that the vertical part (16), at its lower end, is in contact with one side surface of the vertical part (18), and that torsion-stabilising elements (10, 11, 12, 13) are in contact with the other side surface of the part (18) so that the latter is located in a gap formed between the vertical part 16 and the elements (10, 11, 12, 13).
4. A thermally compensated structural element in accordance with claim 3, characterised in that there are cutouts in the vertical part (18) over the areas where the torsion-stabilising elements (10, 11, 12, 13) are in contact with it.
5. A thermally compensated structural element in accordance with claim 3, characterised in that the torsion-stabilising elements (10, 11, 12, 13) are plate-shaped and are also permanently connected to the element (2) at their upper ends and possibly partially at their vertical sides.
6. A thermally compensated structural element in accordance with claim i, characterised in that several lower elements (3, 3', 3") form part of the structural element (1) and are also mounted so that a gap (70) is formed between them.
7. A thermally compensated structural element in accordance with claim 1, characterised in that the base part (17) is equipped with through cutouts (20, 21, 22, 23, 24, 25, 26, 27) which extend some way in from one side of it.
8. Use of a thermally compensated structural element as defined in accordance with claims 1-7, characterised in that one or more thermally compensated structural elements form part of a base frame for a cover for use in a thermal process such as calcining of carbon bodies.
