Self supporting prefab reinforced concrete ceiling - has rib system and is joined to site concrete for adequate thickness

摘要

Elements in a ceiling made from prefabricated sections of reinforced concrete ready for installation, can be used anywhere in building above or below ground, or in engineering structures. The self-supporting parts (1) have a ribbed configuration (2) on a ceiling approx. 4 cm. thick, adequate for loading. S The ceiling is subsequently joined to site concrete (3), producing the complete cross-sectional size ultimately required. The bottom main reinforcement (4) can be inlaid in the 4 cm. slab, and min. pressure reinforcement is required. Ribs pref. lie approx. 2 cm. below the top ceiling edge. Material and work involved in columns and other supports are saved.
