Technical description of the product
The Miyanaga ANZEX undercut anchoris an anchor made of galvanised steel which is placedin an undercut hole and anchored by mechanical interlock with displacement‐ controlled
insta‖ ation,

The product description is given in Annex A

2

Specification of the intended use in accordance with the applicable European
Assessment Document
The pettormances given in Section 3 are only valid ifthe anchoris used in compliance wvith thespecifications and conditions given in Annex B.

The verifications and assessment methods on which this European Technical Assessment isbased lead to the assumpdon of a wor【 ing life ofthe anchor of atleast 50 years The indicadons
given on the working life cannot be interpreted as a guarantee given by the pЮducer〕 but are to

be regarded only as a means for choosing the right products in relation to the expectedeconomica‖ y reasonable working life ofthe works.

Anchorages sublectt。

:。 Static and quasi‐ static loads and seisnlic loads of category Cl and C2

Base materials:。 Reinforced or unreinforced normal weight concrete according to EN 206‐ 1:2000。 Strength ciasses C20/25to C50/60 accoHding to EN 206‑1:2000。 Uncracked or cracked concreteUse conditions(enVirOmmental conditions)・ Anchorages subiect tO dry internal conditions.

Design:。 Anchorages are designed underthe responsib‖ ity of an engineer experienced in anchorages and concrete work.
・ Verifiable calculation notes and drawings are prepared taking account of the loads to be anchored,The positionof the anchor is indicated on the design drawings(e.g・ positiOn of the anchor relative to reinforcement or to
suppotts etc.).

・ Anchorages under static or quas卜static actions are designed for design method A in accordance with
FprEN 1992‐ 4:2016 and EOTA Technical RepOn TR 055.
Bnsta‖ ation:

・O

Hammerd耐 ‖ing only
Anchor installation carried out by appropriately qualified personnel and under the supervision of the person
responsible for technical matters of the sitet

・ Use ofthe anchor only as supplied by the manufacturervvithout exchanging components of an anchor.
・ Anchor insta‖ ation in accordance with the manufacturer's specifications and drawings and using the appropriate
tools listed in Table B3.

・ Thickness ofthe fixture corresponding to Table Bl
・ The concrete sha‖ be we‖ compacted,e.g.vvithout significant voidseCleaning the bore hole and insta‖ ation ofthe anchorin accordance with Annex B5,B6and B7

・ Keeping ofthe minimunl edge distance and spacing(Table B2)。 Positioning of the dri‖ holes and the undercut wvithout damaging the reinforcement
・ in case of abotted hole,dri‖ ing of new hole at a minimum distance of Mice the depth of the aboned hOle,orsma‖ er distance provided the aborted dri‖ hole is fi‖ ed、″ith high strength mortar and no shear or oblique tension
ioads in the direction of aborted hole occur.

・ The insta‖ ation torque moment given in Table Bl to both nuts sha‖

be applied using a calibrated torque wrench。

・ Shearioading、 ″ith lover arm and fastenings through a groutlayer are not a‖ owed under seisnlic toadings.
・ For app‖ cations under seismic ioading the fastening sha‖be placed outside of critical areas(o・g.plastic hingesof the concrete structure)。
