Description
Изобретение относитс к строитель ству и может быть использовано дл исследовани структурных нарушений в конструкци х.The invention relates to the construction and can be used to study structural violations in the structures.
Целью изобретени вл етс повышение надежности при исследовании процесса отслоени бетона от внутренней стенки оболочки.The aim of the invention is to increase reliability in the study of the process of detaching concrete from the inner wall of the shell.
На фиг.1 изображена композиционна 1конструкци ,разрез; на фиг,2 - схема размещени датчика.Figure 1 shows a composite structure, section; Fig. 2 shows the layout of the sensor.
Способ осуществл ю т следующим образом .The method is carried out as follows.
Во внешней оболочке 1 конструкции выполн ют отверсти 2. В каждое отверстие устанавливают электропровод щий датчик 3 так, чтобы поверхность контакта оболочки и бетона пересека- ла датчик. Затем оболочку заполн ют бетоном 4, продавлива его сквозь отверсти 2 до образовани на внешней поверхности оболочки грибообразной шл пки 5, Далее бетон вьщерживают до отвердевани .In the outer shell 1 of the structure, holes 2 are made. Into each hole, an electrically conductive sensor 3 is installed so that the contact surface of the shell and concrete intersects the sensor. Then the shell is filled with concrete 4, pushing it through the holes 2 until a mushroom head 5 is formed on the outer surface of the shell. Next, the concrete is held until it hardens.
В процессе нагружени конструкции может происходить разрыв адгезионных св зей между оболочкой и бетоном, что приведет к, нарушению монолитности со - In the process of loading the structure, the adhesive bonds between the shell and the concrete may break, which will lead to a breakdown of the solidity of the joint.

единени . Между оболочкой 1 и бетоном 4 образуетс трещина 6. По мере приложени нагрузки трещина 6 распростран етс по границе контакта оболочки и бетона, встреча на своем пути бетонные выступы 7 с замоноли- ченными в них датчиками 3, срезает их и тем самым указывает о границе своего распространени . Наличие грибков позвол ет жестко соединить бетонный наполнитель, оболочку и датчик.unity Between the shell 1 and the concrete 4, a crack 6 is formed. As the load is applied, the crack 6 spreads along the contact boundary of the shell and concrete, meeting the concrete protrusions 7 with sensors 3 embedded in them, cuts them off and thus points to its boundary distribution. The presence of fungi allows you to rigidly connect the concrete filler, the shell and the sensor.
