Grapple for logs
Bubník, Tomáš ; Mergl, Václav (referee) ; Kašpárek, Jaroslav (advisor)
The presented work deals with the design of a collet grapple for handling wooden logs and lumber. The work contains a research part of current versions of grabs from both Czech and international companies. It discusses the methods of performing the most used variants of the kinematics of the collet movement, the description of individual technical components and their functions. In the construction part, the work deals with the choice of suitable materials and electrodes, the design of the dimensional parameters of the grapple, the design of a double-acting linear hydraulic motor, sliding and joint bearings and supporting shafts forming rotational connections, a tie rod loaded for buckling and tension, a hydraulic rotator and the design of suitable dimensional parameters of the claws of the collet. An unloading set consisting of a hydraulic arm and an unloading hoist is designed for the grab, for which a stability check is carried out. The result of the work is a functional collet grapple made of high-strength steel for handling wooden logs of smaller weight.

Kunčík, Václav ; Barnat, Jan (referee) ; Šmak, Milan (advisor)
The major objective of this study is to design and statistically assess two variants of the roof construction at log cabin. The first option is wooden prism. The secon option deals with woundwood. The building has 2 floors – above ground floor and partly residential accit. Roof construction is formed by two intersecting gable roof frames. Ground pland dimension of roof construction is 22x13,3 m and the height of the higher roof frame is 6,6 m. The building is situated in Krkonoše near by Špindlerův Mlýn. Climatic load ares considered in both variants.

Family house load-bearing structure composed of thin-walled steel members
Bulíček, Radek ; Melcher,, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The aim of the bachelor thesis is to design and verify load bearing members of single-storey family house composed of thin-walled cold-formed elements. Parking space for cars of timber members is the part of the house, too. The family house is in rectangular plan with dimensions of 9.5 x 10.5 m. The roof of the house is hipped, on the side of the house with the parking place rafters are associated with garage rafters. The following elements were statically assessed: structural members of the house roof (rafters, collar tie, roof bracing), structural members of the ceiling (ceiling beams), reinforcing timber frame, external and internal load bearing walls (columns), load bearing elements of the parking space (rafters, purlins, columns). All assessments were performed according to currently valid standards. The calculation showed that the resistance and serviceability of all components are satisfied.
