  • Patent number: 9889578
    Abstract: A method for casting a hollow core concrete product with a substantially horizontal slipform casting process, where concrete mass is fed at least in one feeding stage through a limited cross-section (5, 6, 7) moving progressively along with the cast, and at least one core is formed in the concrete product to be cast with a core forming member (4), wherein the thickness of webs between the cores of the product to be cast are changed during the slipform casting process by changing the width of the at least one core forming member (4). The invention also relates to such an apparatus and a core forming member.

  • Publication number: 20140145361
    Abstract: A method and an apparatus for casting concrete products with a substantially horizontal slipform casting process, where concrete mass is fed through a restricted cross-section defining the product to be cast, and which restricted cross-section moves progressively along with the casting process in relation to a casting bed, wherein the height of the cast product exiting the restricted cross-section is measured during the casting process, and the height and/or position of the leveling plate of the upper surface of the restricted cross-section is adjusted during the casting process based on the height measurement of the cast product.
