| 摘要 |
The present invention concerns an arrangement for a wall or roof section constructed of elements (1), comprising a first extended U-shaped profile (2), or a track, and a second extended U-shaped profile (3), or a track, whereby the profiles (2, 3) are intended to take between them one or several sheet-shaped elements. Along the side surfaces of the element, a reactive material (4; 12), intended to meet the side surface of the neighbouring elements, is arranged that is capable of expanding (4'; 12') to at least ten times its own thickness on heating on a temperature that exceeds 100 DEG Celsius, filling and sealing against the neighbouring element. Furthermore, a track or a depression (7; 10) may be arranged along the side surface of the element for receiving the reactive material (4; 12) and the depression (7; 10) preferably demonstrates such a depth that the reactive material is located within the outer edges of the element when in its inactivated condition. |
