【 摘 要 】

In this work we analyze existing technologies of installing window blocks in the zone of insulator of external walls, which are used when building multi-storey residential buildings in mass constructions. The comparison was made on a number of parameters (providing normative sanitary and hygienic parameters during operation, the possibility of carrying out work from inside the room, etc.). On the basis of the analysis, a remote installation system of window units in the insulation zone is proposed, which allows year-round performance of glazing of multi-storey residential buildings with external walls with mineral wool or basalt insulation. To substantiate the possibility of using the system in climatic regions with low outdoor temperatures during winter operation, a laboratory experiment was set up. A model of an external wall with a mounted window unit was assembled for the experiment. During the experiment, the actual work of the proposed system for installing window units was simulated in negative outdoor temperatures (-20 °C).The experiment showed that the proposed technical solution of the system meets the requirements of the current regulatory documents on sanitary and hygienic parameters of premises. Studied technical solution for installing window blocks in the insulation zone of external walls is proposed to be used for glazing typical multi-storey buildings in mass constructions as well as in high-rise buildings with increased requirements of thermal protection in external enclosing structures. A plan is proposed to study the system further. It is planned to develop a method for statistical calculation of structural elements of the system components for the effect of operational loads (wind pressure, the own weight of the window unit, etc.), to optimize the technology for various structural variants of the external walls.
