Abstract
A method and an apparatus for casting concrete products by mold casting, where concrete mix is fed in a casting mold from a casting apparatus moved above the mold, and the concrete mix is vibrated with a vibrator assembly located at least partially in the area inside a nozzle of the casting apparatus, wherein the concrete mix is vibrated in the area inside the nozzle with the vibrator assembly performing only vertical vibrating motion.
Claims9
A method for casting concrete products by mold casting, comprising:
- feeding concrete mix in a casting mold from a casting apparatus moved above the mold wherein the casting apparatus comprises a concrete mix container and a nozzle connected to a bottom of the concrete mix container, wherein an area inside the nozzle defines a casting duct, and
- vibrating the concrete mix with a vibrator assembly located at least partially in the area inside the nozzle of the casting apparatus,
- wherein the concrete mix is vibrated in the area inside the nozzle with the vibrator assembly performing only a vertical vibrating motion and vertical movement of concrete mix inside the nozzle is enhanced with protrusions located on an outer surface of the vibrator assembly in the area located inside the nozzle, or a surface of the vibrator assembly located inside the nozzle is formed serrated for enhancing downwards movement of concrete mix inside the nozzle.
An apparatus for casting concrete products by mold casting, which apparatus is movable above a casting mold for feeding concrete mix in the casting mold, the apparatus comprising:
- a concrete mix container,
- a nozzle connected to a bottom of the concrete mix container, wherein an area inside the nozzle defines a casting duct, and
- a vibrator assembly located at least partially in the area inside the nozzle, wherein the vibrator assembly is adapted to perform only vertical vibrating motion and an outer surface of the vibrator assembly is equipped with protrusions in the area located inside the nozzle, or a surface of the vibrator assembly located inside the nozzle is formed serrated for enhancing downwards movement of concrete mix inside the nozzle.
