Construction technology stage of the perimeter shell of the elementary school in Slažany
Kozla, Dávid ; Nečasová, Barbora (referee) ; Diaz, Yvetta (advisor)
This bachelor thesis solves the building-technological phase of the perimeter shell of the elementary school in Slažany. Specifically, it deals with the cladding of the wooden superstructure of the 3rd floor of the primary school building and the additional insulation of the existing floors. The shell of the superstructure is covered with a wooden cladding and filled with mineral wool insulation. Additional insulation is designed as a contact from facade polystyrene boards. The work is elaborated technical report, thermal assessment of cladding, technological procedures at given stage, transport solution including design of the machine assembly and situation, budget stage with report statement, principles of organization of construction including technical report and drawing of construction site, control and test plan, time schedule and safety.

Creep behavior of oak pegs under tension in dry and wet conditions

Carpentry joints equipped with oak pegs are well suited for applications where increased moisture is not a significant factor. However, for the use in outside conditions, e.g. in the repairs of historical timber bridges, the pegs connecting the two halves of the joint may deform and change their original shape. This happens especially during long-term loading and can be augmented significantly by environmental changes. Creep behavior can play a crucial role for some types of carpentry joints, especially when precise contacts of faces in the joint are required. The paper deals with experimental testing of creep behavior of 16 mm oak pegs under dry and wet conditions loaded by the combination of shear and bending between two planks made of spruce in the direction parallel to grain. The results show that the decrease of theoretical stiffness values over time plays a significant role in the force redistribution in the joint especially due to moisture effects (drop 50-70% of the original stiffness).
