Construction joints in reinforced concrete construction Designing a safe construction process Construction joints are unavoidable in reinforced concrete construction, especially when concreting floor slabs and walls in sections. Their design has a direct influence on load-bearing behaviour, tightness and construction process. Especially with complex geometries, the precise design of the concreting sections is becoming increasingly important. Conventional construction joint removals often require elaborate wooden formwork and numerous adjustments on the construction site. In the case of prefabricated reinforcement cages, tight installation space or unusual geometries, the coordination effort increases significantly. At the same time, the risk of execution errors at the construction joint increases. Stremaform® is a modular construction siding element for the formwork of concreting sections and remains in the concrete as lost formwork. The element can be mounted directly on prefabricated reinforcement cages and, if required, delivered geometry-adapted at the factory. Integrated expanded metal creates a defined, rough joint surface for a force-fit connection of the concreting sections. Concrete advantages ➡️ No dismantling and disposal of formwork material ➡️ Safe and defined geometry of the concreting section ➡️ Reduced effort in tight installation situations and complex shapes ➡️ Continuation of reinforcement work regardless of the concreting date ➡️ Design of the working joint in accordance with regulations For planners and construction companies, this means greater execution reliability and a significantly more stable construction process for multi-phase concreting. Working joints become plannable, reproducible and technically controllable.
