● Can be utilised in all cases for fixing anchor tie bars retrospectively ● Infinitely variable screw-in depth and clamping thickness ● For fixing formwork in in-situ concrete construction work ● Screw-in set as accessory for fastening purposes when assembling precast components as well as for fixing formwork and / or formwork supports for in-situ concrete ● Approved load ratings determined for a 15 N/mm² low concrete strength ● Breaking forces tested and documented by an official testing institute ● Inexpensive solution in all cases where a larger concrete anchor is not necessary This special impact dowel with a Dywidag-internal thread is used by foremen over and over again with enthusiasm. For subsequent anchoring on sites with low loads there is nothing better available, because the according tie bars with a practical coarse thread are used on every site. With the tie bars in suitable length any clamping widths for all kinds of use can be realized. For safety reasons we state the admissible loads for a low concrete strength of 15 N/mm2. That means in practice that the anchors are often installed the next day after concreting and are already loaded. This data are based on extensive tests of the offical laboratory “bautest” in Augsburg. Additionally the admissible loads for concrete strength 25 and 35 N/mm2 are stated for using the dowels in hardened concrete.
