Installation of support bodies

There are several ways to attach growth aids into insulation, distance systems with support bodies (anchors), are one way. To avoid overlapping with the warranty, FassadenGrün recommends only be fit if the insulation is applied and leaseholder "accepted". The mounting is then performed in the finished plastered insulation, mostly with plaster. Alternatively is of course a "preliminary" mounting possible, see below. This page explains the assembly of such distance systems and complements the product sheets of WM 12XX8 (for wire rope) and AS 12XX8 (for wood trellises).

Setting the Distance Length

The wall holder is based on a modular spacer block, the first locally from the actual distance block (hardwood or plastic) and a certain number of the corresponding shims (plastic) together. Also an accurate adjustment is required. Here are, depending on bore, none used or up to 8 or 12 spacers needed (photos). If the thickness of shims are 10 mm, these should be located directly behind the main spacer body seats and only then may, however many, 1.5 mm washers still follow. In varying degrees of surface behind the insulation (renovated old buildings), must the adjustment for each holder be taken into account. With equal surface is the adaptation to a hole completed and the determined the composition of the spacer block then transferred to all the other holes. In any case, the spacer block is assembled such that it protrudes 2-3 mm beyond the outer edge of the wall. In this way, the first 5 mm thick wall seal is compressed during assembly then without the EWIS being deformed. The threaded shaft of the holder is tentatively pushed in with its discs again into the hole until the correct number is reached; spacers and the spacer block are placed perfectly together. If the spacer block is less than 2 mm above, there may be a concave deformation of the large stainless steel cover plate while tightening the lock nut. With the insulation in old buildings, it happens that the insulation, due to irregularities in wall, comes forward further than expected and the supplied support block is not long enough. After consultation with 'FassadenGrün' you can purchase additional distance body or discs in this case.

Drilling into the insulation

Beginners and handyman please note the information about drilling. Insulation is to be cut with cylindrical saw D = 60 mm bit, remove dust and dirt. For the central inner bore use a hammer drill bit  or percussion drill bit with 16 mm diameter. Clean surface of the supporting wall of insulation residues, glue, bumps, etc. and smooth, so that the spacer body of the wall holder gets a smooth, flame proof contact surface. Larger bumps flatten with composite mortar best during gluing of the holder.

Standard-attachment in insulation

Assembly of the internal components

Incorporating threaded shaft and spacer block is usually done using composite mortar and additionally with sieve sleeves if needed (f.eg. in hollow bricks etc.). These are broadly described herein accordingly. The assembly is shown in the photos here for a wall with mineral wool insulation. The photos are from different drill holes and clarify specific problem cases. With Styrofoam insulation, for example, the procedure is the same. The wall mount is completely dismantled or has already been delivered that way. The drill diameter is shaft diameter plus 2-4 mm, an annular gap of 2 mm thickness is better than one of only 1 mm, because the resulting heat bridge is reduced due to the bad heat-conducting layer of the mortar. When using mesh sleeves always drill to 16 mm. Brush and blow out the boreholes multiple times. Then all threaded shanks are first tentatively plugged into their holes. Check whether they stick deep enough and are vertically and horizontally align. If this is not yet the case, drill again, shorten or bend shafts if necessary. With bent threaded rods mark with grease pencil (in the photo yellow) a point which facilitates later the correct plugging, thus ensuring a proper procedure during bonding. When bonding one should proceed according to the instruction sheets of the composite mortar. The drill holes and mesh sleeves are sufficiently well filled with mortar, so that emerging composite mortar can be used as single-mass for the hardwood body simultaneously. For ledges and corners, in the area around the inner hole, there additional composite mortar is applied as 'adhesive', thus the hardwood body is sufficiently embedded and later completely secured. Then the threaded shafts and supporting bodies are glued. If several support bodies installed (for example 8 + 4 cm), Insert the longer first. The loaded support bodies are pressed firmly against the load-bearing interior wall and facilitate the locking of the threaded rods, if necessary, are additional aids such as matches or toothpicks to be used. After inserting a threaded shank in the precipitated borehole with composite mortar, the shaft should have (5 - 8 cm, depending on the insulation thickness) the chosen projection over the outer wall and be aligned vertically and horizontally. A subsequent correction of the insertion depth after the curing of the mortar is not possible, only an adjustment if necessary, by bending or metered beating can induce change. The rear support body is bonded quasi at the inner load-bearing wall. If the full load carrying capacity of the shaft is achieved according to the setting time indicated on the mortar cartridge, the further assembly takes place.

Installation of external components

The shims are now placed, as described above, under 'adjusted distance length'. Then the stainless steel cover plate is placed on, sealing ring points in the direction of plaster. The spring washer and the two nuts follow, a clamping nut, and the other as a lock nut for Phillips or eyelet. To counter the crosshead, unscrew the Allen screw and insert a flat tool to secure through one of the grooves. Finally with all holders - also with variations where the holders were not disassembled - The thrust nut, using the wrench, is tightened until a further turn at a relatively high hand force is not possible, and the entire holder is tight. The head fixed with a second wrench or similar to prevent re-twist, if installed with releasable threaded plugs. Only through this powerful stress is the item at its capacity. The rest of the assembly is the same as described for Heavy kits.

Special case pre-assembly

In exceptional cases, it is possible to mount distance systems before reinforcing mesh and synthetic resin plasters are applied. The process is similar to as described above, the glued tops are then taped with painter crepe, the plastic discs and the outer components mounted but only after filling or spraying of plaster, when it is cured. To the holes be cut free with a box cutter.
