Abstract

A method and an apparatus for casting concrete products with a substantially horizontal slipforming process, the concrete mass in said method being fed by means of at least one feed element (2) through a limited cross section (11, 7, 8) for forming the concrete product, whereby the feed elements (2) are brought to a dual-frequency longitudinal reciprocal motion for compacting the concrete mass.

Claims (9)

1. A method for casting concrete products with a substantially horizontal slipforming process, the concrete mass in said method being fed at least by means of one feed element (2) through a limited cross section (11, 7, 8) for forming a concrete product, characterized in that the feed elements (2) are brought to a dual-frequency longitudinal reciprocal motion for compacting the concrete mass.
2. A method in accordance with Claim 1, characterized in that the product to be cast is a concrete product equipped with at least one hollow core, whereby in addition to the feed elements (2), also the hollow-core forming elements (6) are brought to the dual-frequency longitudinal reciprocal motion.
3. A method in accordance with Claim 1 or 2, characterized in that the length of the short reciprocal motion of the dual-frequency motion ranges from 0,2 to 4 mm with a frequency from 15 to 50 Hz, and that the length of the long reciprocal motion ranges from 5 to 40 mm with a frequency form 1 to 10 Hz.
4. An apparatus for casting concrete products with a substantially horizontal slipforming process, said apparatus comprising at least one feed element (2) for feeding the concrete mass through a limited cross section (11, 7, 8) for forming a concrete product, characterized in that the apparatus comprises means (4, 5) for bringing the feed elements (2) to a dual-frequency longitudinal reciprocal motion for compacting the concrete mass.
5. An apparatus in accordance with Claim 4, characterized in that the apparatus comprises means (6) for forming at least one hollow core to the concrete product to be cast, said means (6) being brought to the dual-frequency longitudinal reciprocal motion together with the feed elements (2).
6. An apparatus in accordance with Claim 4 or 5, characterized in that the length of the short reciprocal motion of the dual-frequency motion ranges from 0,2 to 4 mm with a frequency from 15 to 50 Hz, and that the length of
7 the long reciprocal motion ranges from 5 to 40 mm with a frequency form 1 to 10 Hz.

7. An apparatus in accordance with any of the Claims from 4 to 6, characterized in that the feed element is a feed screw (2).
8. An apparatus in accordance with any of the Claims from 4 to 7, characterized in that the apparatus comprises means (12) for moving the apparatus along the casting bed (11) during the cast.
9. An apparatus in accordance with any of the Claims from 4 to 7, characterized in that the apparatus comprises a fixed casting station and movable casting beds.
