With a total of two patents to his name, Ottmann has developed innovative methods and apparatuses that enhance the efficiency and quality of concrete pipe production.
Latest Patents
Ottmann's latest patents focus on an apparatus for making concrete pipe. This invention details a method and apparatus for the vibration treatment of concrete pipe, aimed at achieving compaction and residual stress relief. The process involves forming a concrete pipe within an external jacket using a rotary packerhead method. The jacket is positioned vertically, and the packerhead is moved progressively upward, rotating and distributing the mix radially outward while troweling the internal surface of the pipe. Upon completion, the green pipe is removed from the machine and transported to a hollow, vertically split, radially expandable and contractable cylinder. The pipe is lowered around the cylinder, which is then expanded to engage the internal surface of the pipe. A vibrating mechanism within the cylinder is activated to vibrate the pipe along its length. After this treatment, the pipe is returned to the machine for a finishing pass, ensuring a smooth internal surface and filling any voids. The apparatus includes various components such as the expandable cylinder, rollers for intermittent rotation, guide means, fluid operable cylinders, and multiple vibrators mounted on the cylinder wall.
