Before the partition wall is erected, the alignment is drawn on the floor. For this purpose, a line is stretched and the alignment marked at about 1000 mm intervals. The marked line is marked with marking-out mark (bird’s-mouth). Since the tenons of the posts are accommodated in the mortises of the foot and head runners and the stiffening transoms are also provided with tenons, the whole partition wall is to be assembled before it is erected.
Assembling is done either flat on the floor or in inclined position supported by an auxiliary structure.
The foot runner is to be placed in parallel with and as closely as possible to the alignment. The aligned partition wall is to be moved as a whole.
When the partition wall has been erected according to the scribed markings, it is to be secured against falling off. This can be achieved by wedges to be driven in between the wall post and the wall.
When the partition wall has been secured against falling off, holes are to be bored into the foot and head runners for anchoring them.
The diameter of the holes depends on the shank diameter of the hexagon-head wood screws used for anchoring.
The distance of the holes should not exceed 1000 mm.
When placing the hexagon-head wood screws, the washers must not be forgotten.
When the screw is tightened by means of an open-jawed or ring wrench, it is to be made sure that the washer penetrates the wood of the runner together with the screw head.
