PRECAST CONCRETE ELEMENTS150 CPI %u2013 Concrete Plant International %u2013 3 | 2025 www.cpi-worldwide.commise the load-bearing capacity. 11,000 M16 BT turnbuckles are used to securely connect the elements.BT turnbuckle %u2013 the quick and dry connectionThe BT turnbuckle enables precast concrete elements to be connected quickly and precisely without the use of additional grouting materials or special tools. The connection is made using a dry screw connection that can be loaded immediately and requires no curing time. This means that construction times can be reduced and downtimes avoided. Even in difficult weather conditions, such as low temperatures or precipitation, installation is possible without any problems.Another advantage of the BT turnbuckle is that it can be disassembled, making it suitable for temporary structures. The connection remains permanently stable and resilient, but can be loosened as required. The system is available in sizes M12, M16 and M20 and in both galvanised and stainless steel versions. The general building authority approval and type approval (Z-14.4-599) as well as the European Technical Assessment (ETA 19/0013) confirm the reliability and applicability in the construction industry.The BT turnbuckle is used in a variety of applications, including residential and commercial construction, flood protection, agriculture, civil engineering, and, as mentioned above, temporary structures. Its easy handling and high load capacity make it an efficient solution for joining precast concrete elements.So natural, so robust %u2013 for a lifetime Oberndorf hybrid systems combine the advantageous material properties and connection solutions of wood and concrete. The wooden structures arranged in the lower ceiling level are not only sustainable and visually eye-catching, but also perform well. They support the concrete by absorbing the tensile forces and thus contribute significantly to the stability of the ceilings. A better indoor climate and the well-being of the user are pleasant additional effects.The systems offer numerous advantages and actively contribute to sustainable construction. They are characterised by a good carbon footprint and therefore make an important contribution to climate protection. Depending on the requirements, they can be used to create a finished soffit that is both aesthetically pleasing and functional. Large spans with low component thickness enable efficient designs that save both space and material.Another advantage is the optimised use of materials, which helps to conserve resources. The protective concrete layer also reduces the risk of weathering during installation, which minimises construction delays. Quick and easy installation means that projects can be realised efficiently, saving time and money. The systems from B.T. innovation GmbH therefore stand for sustainability, efficiency and high construction quality.The Oberndorf hybrid systemAs one of the largest precast concrete companies in Austria, Oberndorfer has more than 100 years of experience in the design, development and production of precast concrete products. These skills are still the driving force behind all projects today. In keeping with the company's tradition, it is constantly striving to take new steps, expand its expertise and apply it to future projects. This means that complete solutions can be offered for construction projects of all sizes and comBT turnbuckle in use
