Properties of wood of different ages considering heat exposition
Helanová, Ester ; Hradil,, Petr (referee) ; Vaněrek, Jan (advisor)
This thesis discusses the experimental verification of sorption and mechanical properties of fir wood from the 17th to 21th century. The wood of different ages is thermally treated with temperature of 60°C, 120°C and 180°C for a 17 hours. The effect of thermal treatment of wood on the isothermal sorption characteristics and compressive strength in fiber direction is evaluated.
Dendrochronologické datování a stavebně historické hodnocení krovu sv. Valentína v Bravanticích
Bužek, Stanislav
The aim of this bachelor thesis was, by using the dendrochronological analysis, to date the wood truss roof structure of the main nave and presbytery of the church of St. Valentine in the village Bravantice, township Nový Jičín. This seminar thesis describes a standard procedure from dendrochronological sampling anatomical identification, their modifications, measuring up to the actual dating. The truss above the nave is from the year 1662-1663; roof over the presbytery is younger, the final year of the 1834-1835. On the whole truss structure of the church was used fir wood. Dates detected dendrochronological analyses were compared with historical data derived from the available historical sources and Internet resources. The construction and historical development of the monument remained only a very small number of literary sources. The results of the analysis Dendrochronological truss structure gave us the exact date of construction, and partially uncover and add still unclear historical and architectural development of the church.
Dendrochronologické datování a stavebněhistorické hodnocení krovu kostela sv. Jana Křtitele v Hlučíně
Rataj, Tomáš
The aim of this thesis was to conduct a survey and documentation of construction and the historical development of Object church. John the Baptist in Hlučín, district Opava. The available resources and literature to chart the history of truss structure and determine its typology. Anatomically determine tree species in different parts of the roof structure of the church and using dendrochronological analysis to determine the age of the samples. The work deals with a methodical procedure from dendrochronological sampling, treatment and subsequent measurement until after dating results with comparison using statistical methods within specified Czech and Moravian standard chronologies of tree species. The work is complemented by the resources available on the historical development of building construction. As a result, based on microscopic slides of the samples was identified fir wood. There have been a historical summary of the aspects related to the construction and definition of the age of the individual parts of the roof structure. The truss nave was dated to 1890, the age of the truss presbytery was designed in 1732. Truss above the nave was defined as longitudinally coupled rafter construction Hambálková, stagnant faeces. Historical evaluation of extended documentation package, which is now the object of the church we can leave to future generations. Dating age truss church confirmed the historical development of the subject and contributed to the overall mapping of the now almost restored monument.
