Usage

Please also use the tips for optimal trellis attachment. A cost-effective option for permanent corrosion-free wall mounting of commercially available wooden trellises and especially for cross beams of classic wooden trellis on walls with insulation, in conjunction with a modeled support cone. Usable up to 12 cm insulation thickness. Without cutting the facade. The material width of the wood parts to be fastened should - due to the required through hole of 12 mm - be at least 27 - 30 mm in order not to weaken the cross section too much.

Depending on the shaft length s. below wall distance (gap) of approx. 2 - 4 cm. The actual wall distance is calculated from the wall gap and the sum of the screwed cross-sections and can be up to 10 cm at Latten strengths of about 27/27 mm. For wide trellises, place an anchor bolt in the spar at a distance of 1.0 to 1.5 m (depending on the thickness and deflection of the wood cross section).

The wall gap should be as small as possible, so be about 20 mm, for static reasons. The column "masonry with plaster" is to be used when the thermal insulation has been applied to an old building with exterior plaster (under the insulation).

Different lengths according to the article numbers of the table, the 3rd and 4th numbers indicate the shaft length in cm. The applications already take into account approx. 1 cm extra length for the reinforced external plaster and the adhesive layer of the ETICS. Please only use the column "masonry with plaster" if the thermal insulation has been retroactively applied to an old building with existing exterior plaster.

Please note: The table is valid for the attachment of trellis bars with approx. 30 mm thickness. If, for example, delicate prefabricated trellises with, for example, only 10 mm material thickness are fitted, a 20 mm shorter anchor bolt must be selected in each case. The strength of the insulation means the pure insulation layer, in the shaft length are also about 1 cm reserve for adhesive layer and plaster included.

 

Recommended Tools

Hammer drill bit HB 16310, alternatively percussion drill bit SB 16400.

 

Installation

Please observe the sequence of steps for planning and executing wood trellises and the leaflet on drilling and the instructions for the composite mortar. For optimal sealing, the plaster should be reasonably level or prepared (sanded). The wooden parts to be fastened receive a through hole of 12 mm at the respective fixing points, the wall is given a bore of 16 mm in order to be able to fill a 2 mm annular gap with the poorly heat-conducting composite mortar (interruption of the direct contact between the anchor bolt and the substrate, reduction of the thermal bridge). Drilling depth approx. 10 - 13 cm depending on the desired wall distance. For hollow masonry additionally use extra long sieve dowel SD 16130, bore then approx. 140 mm deep. Then drill the borehole conically in the area of ​​the insulation to the rear using a masonry drill, aspirate or blow out. The circular cone base should be about 10 - 20% smaller in diameter than the insulation thickness, so at 10 cm insulation about 8-9 cm circle diameter. Caution: The front of the hole should not be much larger, otherwise the seal will not grip. If possible, drill with smaller diameter, so 8-10 mm. Cool the composite mortar in refrigerator or cold water first to extend curing time! Then, at the same time as the actual drill hole, fill the milled cavity to about 2/3 - 3/4 with mortar.

Move moving parts of the anchor bolt to the head, insert the shaft into the composite mortar, position it and, if necessary, secure it against sagging from below while setting. Remove swelling mortar with a cloth.

The displaced mortar now also fills the rest of the cavity. If the holes are too large, use the mortar as a filler to re-create a sufficiently large support for the seal. Form the supernatant and sand off after hardening. After setting, the composite mortar has formed a supporting body that is connected to the loadable wall. After setting, push the cover plate together with the laminated seal to the wall and gently press through the first of the two flat nuts until only a narrow visual gap between the cover plate and the wall can be seen. This optimal condition is permanently fixed by clamping both flat nuts against each other with the help of two wrenches ("counter"). Subsequently, the respective spar is mounted between the two spring washers and hex nuts on the front shaft of the anchor bolt.

 

Origin

“Made in Germany”, hex nuts from Far East.

Greenery on external insulation
Stainless steel anchor screw
Rear view: For the AS 12XX4 series for thermal insulation, the sealing disc is made of a 5 mm thick special foam, so that even at low pressure of the adjusting nut, a seal is achieved on the low-pressure base.
Attachment in thick insulation
The support cone in the pierced insulation (red) helps to increase the bending resistance of the element.
