  • Publication number: 20230400579
    Abstract: A method for repeatedly measuring the position of a construction device on a construction site, wherein a position is measured relative to at least two, the method comprising: a. directly measuring the distances from a position measurement system arranged and/or formed on the construction device to at least two of the markings located in a field of view of the position measurement system and measuring the apparent viewing angles of the at least two of the markings from the position measurement system to carry out a first measurement of the position of the construction device and b. taking a bearing of at least two of the markings from the position measurement system to carry out a second measurement of the position of the construction device.

  • Patent number: 11745327
    Abstract: A tool guide has a mounting, a lifting mechanism, and a chassis. The mounting is for fixing a hand-held machine tool. The mounting is mounted on the lifting mechanism. The lifting mechanism has a propulsion unit for vertically lifting the mounting. The chassis has two wheels on a wheel axle, a drive coupled with the wheels, and a steering system. The lifting mechanism is rigidly mounted on the chassis. A center of gravity sensor is arranged to detect a lateral deflection of the center of gravity of the lifting mechanism relative to the wheel axle. The steering system is configured to control the drive to deliver a torque counteracting the lateral deflection.

  • Publication number: 20230186451
    Abstract: A method of monitoring a building element includes using an image capturing device and a computing device, in attributing a visual feature to each one of a first and a second region of the element; taking a first plurality of images of the visual features by the capturing device at a first point of time; taking a second plurality of images of the visual features by the capturing device at a second point of time; causing the computing device to process the images of the first and the second plurality of images to derive at least one of distances between the two visual features and relative orientations of the two visual features within the first and the second plurality of images; and causing the computing device to deduce a state of the element from at least one of the difference between the distances and the difference between the relative orientations.

  • Patent number: 9233458
    Abstract: An installation method for an expansion anchor is carried out by repeatedly exerting rotary-percussive strikes onto the shank (2) of the expansion anchor (1) by an impact screwdriver. The repeat rate (Ntarget) of the rotary-percussive strikes is selected as a function of the tightening torque prescribed for expanding the expansion sleeve (3) of the expansion anchor (1). The impact screwdriver stops generating rotary-percussive strikes when the detected mean rotational speed (d) of the shank falls below a threshold value (D).

  • Publication number: 20140345110
    Abstract: In an anchor system, for example, an undercut anchor system, having an anchor bolt with an expansion element, preferably at least one engagement means for the purpose of bearing a load, an expansion sleeve surrounding the anchor bolt, a means for detecting an axial end position of the expansion sleeve on the expansion element when the expansion sleeve is expanded and moved axially, the axial end position of the expansion sleeve should be able to be detected precisely. This problem is solved in that the means has a sensor for the purpose of detecting the axial end position.
