Fremgangsmate for stoping av et betongprodukt med hul kjerne i en horisontal glideforskalingsform, samt apparat til bruk ved fremgangsmaten.

摘要

The top surface height level and profile of the concrete product is measured. The relative proportion of the concrete mix flowing to the upper layer or to the lower layer of the concrete slab product is controlled based on the measurement results. The relative proportion of the mix is controlled through moving or tilting during the casting operation of the feed trough (12) which is below an auger feeder (2). An independent claim is also included for a fabricating apparatus for hollow core concrete product.
