Development of the project of modular prefabricated buildings
The issues of working design with the construction of modular prefabricated buildings, with the minimization of cold bridges are revealed. Cold bridges are typical for prefabricated buildings with inadequate attention to the design of both load-bearing metal and enclosing structures, as well as their connections. Connections should not pass through its cross section both zero and negative temperatures. As a result, an original project of two modular buildings was developed from easily prefabricated metal structures and wall structures with light mineral wool filling. This project is also intended for sharply continental regional natural and climatic conditions (regardless of the geographical location on the territory of Kazakhstan – south-eastern Kazakhstan, central, eastern or western Kazakhstan. In winter, natural and climatic conditions are similar in these areas). As a result of this study, it was found that the developed project meets the requirements of thermal insulation – at the interface of the supporting and enclosing structures. The thermal insulation requirements of the above structures are important to eliminate the dew point and consequently the formation of moisture and mold in all structures. In turn, mold and other microorganisms, as studies show, adversely affect the health and normal stay of people in the premises, both during the night and during the day. Many developers do not consider these factors in prefabricated buildings. These buildings are intended for various industries. For example, in healthcare, these are mobile hospitals. In military camps – buildings of temporary residence as barracks, etc.
