Research on problems of panel buildings

The purpose of the study is to identify and reveal the main problems arising from the operation of panel buildings, to determine the location of the leakage of joints in panel buildings and to analyze the economic effect of a thermal imaging survey with subsequent repair. The main results of the research consist in analyzing the types of joints of large-panel buildings and their features as well as in conducting the thermal imaging survey of interpanel joints for heat loss and identifying the most problematic areas, according to the results of which heat loss is formed through the vertical and horizontal joints between the panels, as well as at the junction points of the windows. According to the results, the economic effect of the thermal imaging survey shows that the additional costs of paying for heat before overhaul due to the deterioration of the thermal protection quality are many times greater than the cost of the thermal imaging survey, taking into account the additional costs of eliminating thermal protection defects.
