Analysis of the temperature-humidity parameters of structural assembly ?balcony slabs - walling - floor slabs? where efficient thermal insulation

Purpose. Leakage of heat-insulating sheath heat-conducting solid increases heat loss by 10 - 40 %. One of the sites with the most vulnerable in aspect of thermal insulation considered structural unit "balcony slabs - cladding - floor slab". The proposed foreign specialists solutions to minimize heat loss in the area abutting the balcony slab to the outside wall of the building today are expensive, which hinders their widespread in the construction market and makes it necessary to find alternative solutions. Technical solutions to cut off the balcony slab from the thermal circuit of the building, keeping the bearing capacity of a structural assembly is made directly on the construction site by filling permanent formwork reinforced foamed insulation material. The aim of this work is to study changes in temperature inside the enclosing structure and temperature on the inner surface of the wall in the case of the heat insulating member, as well as the definition of the zone of condensation inside the cell. Methodology. At the first stage of the calculation was made microclimate parameters of existing algorithms approved by the regulatory documents of Ukraine. Next, using a specialized program Elcut, failed to compare the character of the distribution of temperature fields in the case of a standard interface balcony slabs and slabs, and in the case of heat-insulating block. Findings. Installed, heat and moisture conditions in the area of constructive node meets the requirements DBN V.2.6-31: 2006 "Thermal insulation of buildings," the risk of condensation on the wall in the area of heatconducting inclusions will be eliminated when using the heat insulating member. On the effectiveness of the proposed solution also shows the reduction of heat loss coefficient equal to 14. The results of modeling the distribution of temperature fields in this constructive node show a reduction of heat loss by using a heat-insulating block. Practical value. Adopt a constructive solution provides temperature and moisture conditions in accordance with the regulations of Ukraine and significantly (14 times) reduces the heat loss caused by heatconducting inclusions. The use of the proposed technical solutions to improve the heat-performance building envelopes in mass construction will significantly reduce heat loss through thermal bridges with little money and labor costs for its production.
