The top reinforcement rail (14) extends along the complete length of the wall, gripping the tops of the wall components (10). It has at least one longitudinal downwardly directed guide flange (15) . which engages in longitudinal guide tracks (16) in the top end parts of the wall components. The reinforcement rail has at least on one side partly an upwardly directed longitudinal edge flange (18), partly a longitudinal, downwardly directed edge flange (17) acting as a back-up fillet. The wall has a lower section formed by the components beneath the reinforcement rail, and an upper wall comprising one or more further prefabricated components fitted above the reinforcement rail on which they rest and grip via their lower end parts around it. |
