Specification

The universal solution for attaching windows in concrete, perforated and solid brickwork and wood

For tension-free installation of windows in the reveal

The hole is drilled through the frame, if necessary an anchor for perforated block or reveal bricks is pushed through

Areas of application:

AMO Combi can be screwed directly into solid block, concrete and wood due to the hardened thread

Can be loaded immediately - no need to wait after installation

Versatile and flexible range of applications, in particular art. no.: 0234 090 250 is ideal for installing windows with frame extensions

Removable anchorage

Notice

It is important to check that the components are correctly installed for the specific construction conditions (e.g. weight of window casement, surface properties, hole pattern in the brick). Accident-proof glazing as specified in the German technical rules for safety glazing (TRAV) or DIN 18008-4 may only be attached with the AMO-Combi screw if the appropriate individual approval has been obtained before installation starts.

Drill perforated and hollow blocks with a rotary drill (without impact mechanism)

When the W-UR 10 XXL is used, the screw is no longer than the anchor and therefore reaches the second chamber in modern filled perforated bricks, ensuring that the anchor is guided correctly into the drill hole and the frame. Consequently the load-bearing capacity is not reduced.

Instructions

Guidelines for planning and executing the installation of windows and house doors, 2020 edition

Art. no. 5995000000

The fixture must safely transfer all standard forces affecting the window to the structure and the foundation. The total load must therefore be calculated from e.g. the window load, wind load and live load (see DIN 1055). The currently applicable building regulations stipulate that buildings and their components must be planned in such a way that they do not endanger human life and health or pose a risk to public safety. Attachment of the windows must also comply with this criterion.

When securing window walls compliant with the former DIN 18056 standard or elements with a surface area in excess of 9 m2 and fall-proof glazing as specified in the German technical rules for safety glazing (TRAV) or DIN 18008-4, the following must be observed

The DIN 18056 standard applied to window walls with a minimum surface area of 9 m² and a minimum side length of 2 m on the shortest side. Anchors with construction product approval, European Technical Approval or with individual approval should be used for this application. Similarly, only anchors with construction product approval, European Technical Approval or with individual approval must be used to attach fall-proof glazing as specified in the German technical rules for safety glazing (TRAV) or DIN 18008-4.
