HOLLOW INTERCONNECTING PANELS AS LOST FORMWORK

摘要

An elongated building element (14) to form a series of walls (10) to (13). T he elements (14) each have longitudinally extending flanges (21) that snap enga ge with longitudinally extending grooves (19) in the next adjacent element (14) . Accordingly the wall (10) is constructed by joining the elements (14) in a direction transverse their general direction of extension. If so required th e elements (14) may be filled with concrete.
