Said top side (11) is provided with a longitudinal recess (17) for receiving a first ridge portion (18) and a second ridge portion (19), the recess extendling continuously between the first gable side (13) and the second gable side (14) for receiving the ridge portions (18,19) in any posistion in the longitudinal direction. The first and second ridge portions (18,19) are arranged at a distance from each other, which distance correspond to or exceeds a distance between the recess (17) and the long side faces (15,16). Fig.1 and Fig.2 illustrates one embodiment of building block (10) according to the inventionin the shape of a rectangular parallelepiped.</p> |
