When the columns have been erected, check that the measurements correspond with the datasheet.
Align the columns with the aid of a spirited level.
They should tilt slightly outwards after dowelling.
Using a masonry drill (nominal drill diameter = 24 mm, maximum diameter = 24,55 mm), place the drill bit over
the drill holes of the base plate and drill approx 200 mm deep into the concrete base.
Regulations for dowelling
General
The dowel may only be used as a standard unit as delivered for its fixing purpose. Individual parts must not be
replaced.
The assembly of the dowel to be anchored must be carried out in accordance with section 3.1 of the construction
drawings and the assembly instructions of the company. Before placing the dowels, the concrete quality of the
foundation where the dowel is to be anchored must be checked. It must not be below the concrete quality
assigned to the permitted load and not above B55.
Drill hole preparation
The position of the drill hole must be such that damage to the reinforcement is avoided.
The hole should be drilled with a hard metal hammer drill at right angles to the surface of the anchor base. The
hard metal hammer drill must comply with the stipulations in the information leaflet of the Institute for Building
Technology about “Nominal values for quality assurance for hammer drills with cutting plates from hard metal
(hard metal hammer drills) which ar used the drilling holes for dowelling connections (edition June 1977/
Amendment October 1979).
Compliance with the nominal drill values must be proven in the form of a test certificate 3.1 A to EN 10 204,
or in form of a test symbol (see information leaflet) of the Testing Guild of Builders’ drills e.V., Remscheid.
The nominal drill diameter and cutting diameter must correspond to the values in appendix 4. If he hole was
not successfully drilled, the new hole should be drilled at a distance of at least 2 x the depth of the wrong drill
hole.
The drill dust must be removed from the drill hole.
Lacing dowels
The dowel should be easily inserted by tapping with a hand hammer. The washer must touch the inserted part.
The torque values can be found in appendix 4.
If the torque value stipulated in appendix 4 cannot be achieved, then the dowel must not carry any weight.
If the threaded bolt or screw is loosened again after insertion, then the threaded bolt or screw must be screwed
in again into the thread cone by at least the measure of the thread diameter and the stipulated torque value
must be applied again.
Mounted dowels can be checked again at any time; the stipulated torque value for anchoring the dowel must
be achieved again each time.
