The fischer injection systems are not only developed, but also manufactured in Germany. From the research of the formulation in the in-house laboratory to the mixing of the ingredients and the injection of the specially developed cartridges, everything is manufactured in one plant in the south of Germany. This enables research results, market trends and customer requirements to be quickly embraced and converted into market ready products.
Our quality management system is certified in accordance with DIN EN ISO 9001. Through the fischer Process System (fPS) we continuously optimize our processes and adapt flexibly to customer requirements. We don’t compromise on the safety of our products. We take part in the leading international, standard-setting councils in the fastening technology sector, thus contributing our knowledge to their work. Our products are characterized by up-to-date international approvals, technical certifications and expert reports. In addition to the external ETA, ICC and fire resistance tests, the products are also tested in our own test laboratory after each production step, e.g. by means of pull-out tests.
Thus the fischer products meet highest quality requirements and guarantee maximum safety for your projects.
When designing chemical anchorage of post-installed rebars with tension loads, two design methods should be considered: design in accordance with anchor theory or with rebar theory. If designing according to the anchor theory the loads in the rebars are transferred into the concrete and depend on the concrete’s tensile strength to resist the load. But when the design is in accordance with the rebar theory, then the loads in the rebars are transferred into the existing reinforcement via compression struts. In this case the design is carried out similarly to cast-in rebars. With this method, the calculations are in accordance with the Eurocode 2 (EC 2). The design models and the building regulations are based on the assumption that the transmission of loads into the supporting structure are in accordance with the reinforced concrete regulations. Any additional national regulations must also be observed.
