Joining of thin walled elements. Investigations on the introduction of compressive forces by the use of implants
Reducing the environmental impact of concrete structures is a significant step for a sustainable building industry. Mass reduction due to an application of high-tech material combined with a focus on design for recyclability of structural elements requires the development of new construction methods. The use of Ultra- High-Performance Concrete (UHPC) with its advantageous properties allows for the construction of thin walled, prefabricated elements and aesthetically pleasant structures. Requirements for the assembly, disassembly and therefore recyclability as well as the compensation of tolerances and the accessibility of the gap between joined structural elements have to be taken into account for joining prefabricated elements on site. The authors present a construction method under consideration of the aforementioned requirements for joining thin, prefabricated elements made of Ultra-High-Performance Fibre Reinforced Concrete (UHPFRC) by the use of implants. The implant development, first results of experimental investigations and a general outline on the design for assembly and disassembly will be given in the context of recyclable and sustainable structures.
