Thermal Protection Properties of the Wall Panel of the BKR-2C Series Three-Dimensional Block with Flexible Connections

The authors carried out full-scale tests of the external wall panels of the BKR-2C series three-dimensional block with flexible connections to determine the thermal protection characteristics. Conclusions have been drawn about the need to increase the energy efficiency class of buildings made of load-bearing three-dimensional blocks both at the design stage and at the construction stage. It is shown that the primary task is to increase the coefficient of thermal-technical uniformity to 0.8-0.9. To achieve a high degree of uniformity of the structure, it is possible to replace solid expanded clay concrete dowels and stiffeners with flexible connections made of composite or steel reinforcement. A theoretical model of two-dimensional and three-dimensional thermal field of an external wall panel with discrete and flexible connections is presented. Design and microenvironment parameters are set. Design heat-conducting inclusions have been introduced to calculate high accuracy in the software package. The authors obtained data on the efficiency of switching to reinforcement connections. The transition to flexible connections will make it possible to reduce the number of thermal bridges and heat-conducting inclusions, as well as increase the energy saving class to B-high and the energy efficiency class to C-increased.
