| 摘要 |
The invention is concerned with a method to build a cast concrete spaced structure of large dimensions wherein one or more walls, mutually enclosing an angle, are cast and thereafter tilted. A first wall (2) is cast flat lying and thereafter erected whereafter a perpendicular second wall (6) is cast flat lying against the first wall. Thereafter the arrangement of first (2) and second wall (6) is erected such that both these walls extend upwardly, whereafter a perpendicular third wall (7) is cast flat lying against the first (2) and second wall (6). Use is made of a table (8) which is supported such that it can pivot around the horizontal to erect the wall, wherein an edge of the table (8) lowers and/or the tables displaces. During erection, the centre of gravity is displaced by filling or emptying a ballast tank (11,12) such that a tension force is present in a cable (10) used for tilting. <IMAGE> |
