KRAFTMETINSTRUMENT FOR ANKARE INOM BYGGNADSINDUSTRIN

摘要

A dynamometer for measuring forces on an anchor in a building construction. The dynamometer has two closely spaced annular discs enclosing a pressure chamber between them. The discs fit around the head of an anchor between a fixed support and a fixing nut. The chamber between the discs contains pressure medium and in use is connected to a pressure gauge. At least one of the discs has flexible zones adjacent its inner and outer peripheries and the discs are otherwise of rigid construction.
