Abstract

In the fields of mechanical engineering and toolmaking there is a frequent requirement for light but very strong constructional elements of high flexural strength, particularly as constructional components with minimum flexure despite unsupported free lengths. In the case of measurement instruments, for example, there is the problem that the rail (1) must, if possible, suffer no flexure even if used completely unsupported and with external forces acting upon it, if the reading is not to be incorrect. To this end, a constructional element in accordance with the invention with a plurality of bodies (2) made of, for example, ceramics which are connected using prestressing devices (3) or adhesives to form a rigid constructional component is presented. This structure prevents the ceramic elements from fracturing as a result of excessive bending moments since they can tilt or slide relative to each other. The bodies (2) and prestressing devices (3) can be placed in a block which may be provided with external cladding, whether partial or whole.
