An insulating layer (5) which runs parallel to the wall and passes through from one bearing surface to the other and from one abutting surface to the other is arranged between two block parts (2, 3). The two block parts (2, 3) are connected to each other by connecting webs (4) passing through the insulating layer (5). Channel-like passages (8), passing through longitudinally, run in the interior of the connecting webs (4). The side walls (9, 10), directed towards the insulating layer (5) in plan view, of the block parts (2, 3) have rounded-off transitions (13, 14, 15, 16). The insulating layer (5) is provided on one bearing surface with a groove-like depression and on the other bearing surface with a comb-like projection corresponding to the groove width. Likewise, said insulating layer is provided on one abutting surface with a groove-shaped depression (34) and on the other abutting surface with a comb-like projection (35) corresponding to the groove width. <IMAGE> |
