Publication number: 20240133405Abstract: A method can be used for leveling a fastening element to be anchored in a substrate, with fastening element used, for example, for mounting a parapet or glazing. The method involves installing an anchor in the substrate; attaching an adjustment element that is height-adjustable along the anchor to the anchor; and arranging the fastening element on the adjustment element or the anchor in another position defined by the adjustment element. The method further involves leveling the fastening element by adjusting the adjustment element from above using a leveling adapter, which is arranged at least in part above the fastening element and can be gripped and operated from above, in particular by the adjustment element and the leveling adapter interlocking or being releasably interconnected through the fastening element. The method then involves removing the leveling adapter and/or fixing the fastening element to the anchor in the position adjusted in this manner.Type: ApplicationFiled: February 22, 2022Publication date: April 25, 2024Applicant: Hilti AktiengesellschaftInventors: Martin KUHN, Christian Hefele, Oliver Baumann

Publication number: 20240133406Abstract: A device for removing misalignments between flanges of pipeline ends. More specifically, a device that, operated by an ROV, allows flange holes at the ends of subsea pipelines to be aligned so that interconnection operations between said pipelines can be embodied. To this end, the device described herein comprises an elongated metallic body having at least two diameters and presenting a gradual reduction between the component diameters. Additionally, a fixed nut is mounted on the larger diameter side of the elongated body, followed by a manipulator for administration by the ROV. On the other hand, a movable nut is mounted on the smaller diameter side of the elongated body, and the tightening movement made by the ROV on this movable nut causes the device to pass through the holes to be aligned, precisely, in the direction of the larger diameter of the device of the invention.Type: ApplicationFiled: October 17, 2023Publication date: April 25, 2024Applicant: PETRÓLEO BRASILEIRO S.A. - PETROBRASInventor: ANDRE LUIZ BEVILAQUA SANTANA
