Description

Известен сиособ измерени  ианр женнн в бетонных сооружени х посредством парных тензометров, например ст пнпы.х, один из которых станавливаетс  в толще испытуемого бетона, а друго : в участке бетона , ,изолирО ванном жестким мета,1лическим кожухом от его массы, с нрименеиием гидравлического кюмпенсатора, св занного гидропроводом с внешним источником давлени .The method of measuring pipes in concrete structures is known by means of paired strain gauges, for example, st., One of which is set in the thickness of the test concrete, and the other in the area of concrete, isolated from its mass, with hydraulic housing. capacitor connected by hydraulic line with external pressure source.

Отл1ичительной особенностью данного изобретени   вл етс  иной пор док размещени  гидравлических компенсаторсв, располагаемых в нагтраплении, обратном действию на бетон собственного веса и прилагаемых нагрузок, в силу чего напр жени  с тензометров не сн:и гаютс , а воспринимаютс  имд полностью.The distinctive feature of the present invention is a different order of placement of hydraulic compensators located in the heating, the opposite effect on the concrete's own weight and applied loads, due to which the voltage from the strain gauges is not apparent: they are completely perceived.

Такой способ дает возможность исключить искажающее вли ние на точность измерений усадки, разбухаеи  и прочих остаточных деформапиГг бетона м же.лезобетона в месте расположени  11змернте,льных приборов.Such a method makes it possible to eliminate the distorting effect on the measurement accuracy of shrinkage, swelling and other residual deformations of concrete of the same concrete at the location of the 11-dimensional tools.

Under the action of the load and its own weight, the concrete is deformed, causing. in a strain gauge, there is a similar defomation and pressure transfer with the opposite sign to the compensator.
