Concrete element, for parts of buildings and other structures, comprises two parallel outer walls and wall between produced by filling gap between outer walls with fresh concrete to bring the latter into its correct position

摘要

Concrete element comprises parallel first and second walls (16, 12) which are brought into correct position relative to an intermediate wall (14) during pouring of the latter, by pressure, with the fresh concrete. This pressure is directed outwards against the shuttering elements. An Independent claim is also included for a method of producing such a concrete element. It involves introduction of two walls into a shuttering system, and filling the space between them with fresh concrete.
