Abstract: The invention relates to a sandwich element with a central layer (10) made of a foamed filler material, preferably plastic foam, and outer layers, wherein the outer layers are made of pressure panels (2, 3), preferably flat pressure panels, and pressure panels lying opposite each other are clamped against each other by means of clamping elements (4) which pass through the central layer (10), thereby compressing the central layer (10). The invention additionally relates to a method for producing such a sandwich element and to a support, in particular a buoyant platform, which is made of such sandwich elements, including the process of producing such a support.

Abstract: Driverless motor vehicles are conveyed to unoccupied parking spaces in a building by a transport system comprising at least two trackless transport elements and, for each motor vehicle, four detachable wheel support elements on the parking space and the two transport elements, on which wheel support elements the vehicle remains during parking in the parking space.

Abstract: A clamp for holding elongated workpieces in angular abutment with each other includes a base, a first pair of clamping jaws formed by two sides of an angular member, the sides defining between them an angle and an angular sector, a guide on the base for guiding displacement of the angular member on the base along a line bisecting the angle, a lock for locking the angular member on the base, a clamping member displaceable relative to the base along a line parallel to the line bisecting the angle, a pair of first and second levers pivotally coupled to each other at one end of each lever, the first lever being pivotally coupled to the base at an end opposite the second lever and the end of the second lever opposite the first lever being pivotally coupled to the clamping member, and a second pair of clamping jaws, each pivotally connected to one of the pair of first and second levers.
