20.500.12556/RUL-173893 Vpliv konstrukcijskih detajlov na vlažnost lesa v leseni gradnji Influence of construction details on wood moisture in wooden constructions V magistrskem delu smo obravnavali vpliv konstrukcijskih detajlov na vlažnost lesa v sodobni leseni gradnji. Glavni cilj raziskave je bil ugotoviti, kako različne izvedbene rešitve - zlasti ob stikih konstrukcijskih sklopov - vplivajo na navlaženost lesenih konstrukcij in s tem na dolgoročno stabilnost konstrukcije. V okviru analize smo se osredotočili na detajle, pri katerih v praksi najpogosteje prihaja do težav z vdorom vlage, kot so talni zidec (cokel), strešni robovi, stiki z okni ter preboji fasade. Na podlagi konstrukcijskih skic in z uporabo programa Ubakus smo izvedli analize difuzijskega prenosa vlage skozi posamezne sloje sestav. Rezultati kažejo, da detajli brez ustreznih parnih zapor, zrakotesnih plasti in prezračevalnih rež povzročajo akumulacijo vlage v konstrukciji, pri čemer kritične vrednosti relativne vlažnosti presežejo 80 %, kar pomeni povečano tveganje za kondenzacijo in razvoj gliv. Nasprotno pravilno izvedeni detajli omogočajo učinkovito izsuševanje in stabilne razmere v konstrukciji. Na osnovi ugotovitev smo oblikovali priporočila za izboljšanje projektiranja detajlov, ki bodo v prihodnje prispevala k večji trajnosti in zanesljivosti lesenih objektov. This master’s thesis investigates the influence of construction details on wood moisture in modern timber buildings. The main objective of the research was to determine how different design solutions – particularly at junctions between structural elements – affect moisture accumulation in wood construction and thus impact the long-term durability of the structure. The analysis focused on details where moisture problems commonly occur in practice, such as the plinth area, roof edges, window connections and façade penetrations. Based on construction cross-sections and using the Ubakus simulation tool, diffusion moisture transfer was assessed across various material layers. The results show that details lacking proper vapour barriers, airtight layers or ventilation cavities lead to significant moisture accumulation, where relative humidity levels exceed 80%, indicating an increased risk of condensation and fungal growth. In contrast, well-executed detailing ensures sufficient drying capacity and stable internal conditions. The findings served as the basis for a set of recommendations aimed at improving the design of key construction details to enhance the durability and reliability of timber buildings in the long term. konstrukcijski detajli lesena gradnja vlažnost lesa zaščita pred vlago trajnost lesenih konstrukcij construction details timber construction wood moisture moisture protection durability of wooden structures true false false [E.
