Abstract
Denne afhandling adresserer tre sammenhængende problemer: stilstand i byggebranchen, mangel på betalbare boliger og plastforurening. Projektet introducerer en produktionsmetode, der udnytter industrielt plastaffald, specifikt polyoxymethylen (POM). Fremstillingen kombinerer kontinuerlig ekstrudering med additiv fremstilling (3D‑print). Et hjørnebåret, modulært system med stive moduler anvendes. Modulerne færdigproduceres, samles og udstyres offsite i kontrollerede omgivelser. Det muliggør både masseproduktion og massetilpasning, hvilket sænker omkostningerne og kan give boliger af højere kvalitet til en lavere pris. Der er udarbejdet og analyseret flere versioner af etagebyggeri. De påvirkende laster er beregnet, og de bærende dele er dimensioneret ud fra deres virkning. Særligt fokuseres på stivhed (modstand mod nedbøjning og sidesving), fordi POM som materiale er mindre stift end traditionelle byggematerialer. Derfor er brugbarhedskriterierne (serviceability) styrende for dimensioneringen. I højere bygninger tilføjes stålafstivningsstænger for at øge den samlede stivhed. Samlinger mellem elementer og moduler er designet til fuld demontering, så modulerne kan genbruges, fungere som selvstændige enheder, flyttes og til sidst let genanvendes. Tilsammen peger løsningen mod mere prisvenlige boliger og bedre udnyttelse af plastaffald.
This thesis tackles three linked challenges: a stagnating construction industry, a shortage of affordable housing, and plastic pollution. It introduces a production method that uses industrial waste plastic, specifically polyoxymethylene (POM). The manufacturing combines continuous extrusion with additive manufacturing (3D printing). A corner‑supported, modular system with stiff modules is adopted. The modules are fully produced, assembled, and outfitted offsite in controlled environments. This enables both mass production and mass customization, lowering costs and delivering higher‑quality homes at lower prices. Several versions of multi‑story buildings are designed and analyzed. Loads on the structures are calculated, and structural elements are sized based on their effects. The design emphasizes stiffness (resistance to deflection and sway) because POM is less stiff than conventional building materials. As a result, the serviceability limit state (usability and comfort criteria) governs the design. For taller buildings, steel bracing rods are added to increase overall stiffness. Joints between elements and modules are designed for complete disassembly, so modules can be reused, used as stand‑alone units, relocated, and ultimately recycled. Together, these choices point toward more affordable housing and better use of plastic waste.
