Casting method for slab containing channels, used for floors or ceilings in buildings, involves forming channels in concrete layers cast around heating or cooling pipes

摘要

#CMT# #/CMT# A concrete core activating means is cast in an open mold and then a first layer of concrete is cast on top, followed by a second layer of concrete. At least one channel (28) is formed in the first and/or second concrete layer during casting and the concrete core activating means is completely enclosed by the concrete. The activating means comprises one or more heating and/or cooling pipes (6). #CMT# : #/CMT# Independent claims are also included for the following: (A) Slab (23) comprising a concrete upper shell and concrete lower shell, one or both of the shells containing at least one channel extending in the slab length direction and the lower shell containing a concrete core activation means secured to a length reinforcing structure (5); and (B) Floor comprising one or more of these slabs. #CMT#USE : #/CMT# For floor or ceiling slabs in buildings, especially for underfloor heating or climate control systems. #CMT#ADVANTAGE : #/CMT# Climate control can be achieved using relatively little energy. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows an end view of a floor comprising this slab. 5 : reinforcing parts 6 : climate control pipes 23 : floor slab 28 : channels.
