Method of forming a concrete column capital in a standard flat plate concrete slab

摘要

A method of forming a concrete column capital using a flexible tension membrane material in place of the traditional rigid panels currently used for this purpose, is described. A flexible tension membrane material is attached to an opening in a panelized flat slab formwork deck located directly above a pre-existing concrete column. The membrane forms a bag- like container which contains and supports the wet concrete, and serves to form a column capital between the column and the flat slab above. Also disclosed are methods for anchoring the flexible tension membrane capital form to a panelized flat slab formwork deck.
