CONTROL TECHNOLOGY IN PREFABRICATED AND MODULAR GREEN HOME
Abstract
The paper describes the technology of controlling a new material called Polytech used for the production of prefabricated units. Prefabricated units made from a modified Polytech mortar based on expanded polystyrene derived from recycling were used to build a residential object. Prefabricated elements are load-bearing and, at the same time, insulating elements in the form of wall panels. In order to control the prefabricated wall with a lintel under realistic conditions, a control technology was suggested that involved introducing fiber Bragg gratings deformation sensors. The suggested monitoring method enables constant measurements of deformations of a construction element during its exploitation. This is a big advantage of the measuring system, due to the fact that so far Polytech has not been used to manufacture prefabricated units. The most important aspect of this solution are FBG sensors introduced into the building structure. The use of measuring method based on sensors with BraggпїЅs gratings allows constant analysis of operational safety of a given element both, in the construction phase and during the normal use of the building. Reinforcement in the tested points did not deform identically. During implementation of FBG deformation sensors, the localization of sensors in the controlled units is important. Tests carried out by means of fiber optic sensors allow to determine the real scope of deformation of the monitored reinforcement bars used in the Polytech lintel system.
