Snedskarvning som industriell tillverkningsmetod för trälister / Scarf jointing as an industrial manufacturing method of wood laths

Gunnarsson, Johan, Gustafsson, André January 2016 (has links)
Kan snedskarvning vara ett ekonomiskt lämpligt komplement till fingerskarvning? Kvistfritt listmaterial av furu är mycket eftertraktat inom träindustrin där fingerskarvning numera är den mest förekommande metoden. Det är viktigt att listmaterial har en hanteringsstyrka god nog för att hålla ihop vid montering eftersom konstruktionsstyrkan inte är den begränsande faktorn. Denna studie innehåller en jämförelse i draghållfasthet för lister gjorda med fingerskarv, MDF och snedskarv där det lägsta vinkelförhållandet som uppfyller kraven på skarven är sökt från 1:1 till 1:5. Tidigare tester framhåller förhållandet 1:8 när det är till för konstruktionsändamål, denna studie hävdar att 1:3 är tillräckligt för lister. / Could scarf jointing be an economical suitable complement to finger jointing? Knot-free lath material of pine wood is highly requested in the timber industry where finger jointing nowadays is a commonly used method. It is important that the lath material has a handling strength good enough to hold the assembly since structural strength is not the limited factor. This study contains a comparison of tensile strength in laths made of finger joints, MDF (Medium Density Fibreboard) and scarf joints where the lowest ratio of angular relationship that meets the demands of the scarf is searched from 1:1 to 1:5. Previous testing only holds a ratio of 1:8 for construction purposes whereas this study claims a result of 1:3 for laths.

Přepočet a variantní návrh ocelové konstrukce administrativní budovy JmP Brno - Radlas / Static verification and variant design of steel structure of administrative building of Gasworks in Brno - Radlas

Štulrajterová, Terézia January 2016 (has links)
The subject of this master´s thesis is a recalculation of the existing structure, design, static analysis and economic comparison of two variants of this bearing structure of the administrative building Jihomoravská plynárenská located in Brno. Ground plan dimensions and height of both these variants are based on existing disposition of the building. The diameter of the circular floor plan is 16,088 m and height of the structure is 29,46 m. With this new proposal of solution A and B, lower weight of structure in comparison to the existing state has been reached. Both variants have a bearing column in the middle of floor plan and new solution of ceiling structure. The most advantageous from the economic and assembly point of view is variant B. Design of this variant was processed in detail.
