Personalised Formwork – scientific approach for new solution variants

摘要

Application of personalised formwork is of most interest for architects and engineers now-a-days. Although a required demand when designing special constructions, there is little data and material solutions for this case. The cost and domain of application are of most importance in determining new solutions for concrete formworks. To contribute to these requests (a wider usage domain, productive material cost and maintenance), a personalised formwork concept is presented. The idea of reusing the formwork led to an elastic material – membrane (thermoset elastomers, synthetic rubber) with a punching tie-rod solution in order to obtain any architectural shape desired. This first solution was evaluated taking into account different membrane thicknesses. Several experimental tests denoted that the named chosen membrane variants are of low resistance for pouring a concrete architectural slab, so new solutions were discussed. Hence, a re-analysis of the PLM steps was achieved in order to find an answer for the encountered problem. By using creative methods, we obtained a second solution and put it to test. The attained results are used in order to establish the area of workability, to enlarge the tested domain and to assess the sustainability of a new type of personalised formwork
