Vliv tepelných mostů na vznik plísní v panelových bytových domech

Abstract

Since the ancienit times man needed a shelter for protection against climatic influences. User´s requirements have increased step by step. Development in housing came to the introduction and implementation of panel technologies. Today, the panel blocks of flats can be described as one of the typical kinds of dwellings constructed not only in the Czech Republic but also in Europe in the second half of the 20th century. Because of the great volume of construction of blocks of flats in previous years, we have to deal with the question of prolonging their service life to reflect the demands for housing at the beginning of the 21st century. Panel residential houses are known for their faults, especially for the defects of constructions in the field of statics and thermal technology or inappropriate internal microclimate and high demands for energy, etc. As a result of thermal bridges internal surgaces of structures in these places are often affected by moulds. The aim of the thesis is the analysis of four structural variants of the solution of the connection of loggia to staircase wall of the panel system T-06-B from Prefa Olomouc. The advantages and disadvantages of particular variants will be evaluated statistically on the base of the analysis of designed solutions and will serve for recommending appropriate constructional adjustments to minimize the influence of thermal bridges in construction. The secondary objective is to demonstrate the effect of thermal bridges on the rise of mould in prefab blocks of flats and to demonstrate the influence of thermal bridges on the deterioration of internal microclimate. Demonstrating the effect of thermal bridges is done by the results of thermographic measurements and by the results of measurements of surface temperatures on the structures affected by moulds.
