Установка для вимірювання горизонтальної складової тиску в масиві бетонної суміші

Abstract

A device for measurement of horizontal pressure constituent in massif of concrete mix that includes a split body, loading device that is arranged as a punch connected to power drive, symmetrically with respect to the first opening a second opening is arranged, besides that on the split body not less than two more pairs of openings are provided, those are arranged symmetrically at the top, at the middle and at beneath of the side wall of the split body. In the cavity, in front of each of openings on the outer surface of the body, in niches of the inner side surface tensoresistors are installed, at that in front of each tensoresistor in niches of the inner side surface of the split body sliding shutters with con-rods connected to those are installed, the last ones are attached to fixation slat that is hinged with rigid coupling to the lever that is hinged to frame with an eye, those are installed with possibility of synchronous displacement, at that the tensoresistors that are placed under the sliding shutter are connected to the analog-digital transformer connected to blocks for data processing that are placed in front of each opening on the outer surface.
