Systematic Fixing Solutions The advantages at a glance EMU Fixing anchors with internal thread are intended to be used for permanent anchorages under predominantly static actions or quasi-static actions in reinforced and unreinforced normal weight concrete from strength class C20/25 to C50/60. They may be used in cracked or non-cracked concrete for transmission of tensile loads, shear loads or a combination of both.

S Y S T E M AT I C F I X I N G S O LU T I O N S Typical Situations / Load Dia grams Load behaviour In order to clarify the load behaviour and advantages of the different fixing anchor types in different situations, the following gives a short overview of the main applications. The load behaviour – i.e. the load capacity as a function of different concrete classes – of certain types of T-FIXX® is compared with the cor- responding types of DEMU Bolt anchors 1988, as illustrated in the diagrams. A detailed calculation of the load behaviour (with all its project specific influences such as the concrete...

These and further special regulations for dimensioning are included in the DEMU calculation...

GENERAL TECHNIC AL INFORMATION Material and Corrosion Protec tion Corrosion protection Galvanising: Zinc galvanising (GV) Zinc galvanising (chromium VI free) with a passivation treatment is used. The coating thickness is approximately 5–8 μm. After galvanising the products are dipped in a bichromate solution for passivation. The corrosion resistance is limited and depends on the immediate environment. All threaded zinc galvanized products (T-FIXX® anchors, bolt anchors, bar anchors) have a yellow tint. Therefore the anchors are easily to distinguish from stainless steel types. This does not apply...

GENERAL TECHNIC AL INFORMATION Changes in the Produc t Range Changes since 1 st January 2012 The new DEMU anchor, the T-FIXX®, became available on 1st January 2012. It is not a socket anchor and it is not a bolt anchor – it is a clever combination of both, and can be used as a replacement for either product type. T-FIXX® can replace many other socket anchors • In terms of load capacity T-FIXX® can replace all types of socket anchors of the same dimensions and because of its higher performance it is possible that a T-FIXX® of a smaller (thread) M-size can replace larger socket anchors! This will...

GENERAL TECHNICAL INFORMATION Changes in the Product Range Range from 1st January 2012 Alternatives to discontinued socket anchors Discontinued socket anchors (non-stock item). Alternatives (same thread diameter and length)® with nailing plate 2275 with nailing plate 2275 with nailing plate 2275 © Because of its high performance it is possible that T-FIXX® in smaller sizes can support similar loads to larger socket anchors! This will also allow a smaller bolt diameter and reduce costs for the fixing. © 2014 HALFEN ■ DEMU-FIX 14-E ■ www.halfen.com

General Information The DEMU Fixing anchor T-FIXX® with European Technical Approval is an innovative combination of socket anchor and bolt anchor. T-FIXX® is calculable for each situation. 22 standard versions/sizes are available in zinc galvanised (GV) or stainless steel (A4). The zinc galvanised version of the T-FIXX® is yellow galvanised (chromium VI free) and therefore visually distinguishable from the stainless steel types. Anchor description The T-FIXX GV is manufactured from a steel precision tube (strength class E235). The surface is zinc galvanised (GV), the internal thread is metric...
