Shaft walls
■
Shaft wall is a vertical, non-bearing partition construction
meeting the double-sided fire requirements. The shaft
wall can be mounted only from one side. No mineral
insulation is used in the construction.
■
First of all, the shaft wall construction must be laid out.
Apart from other vertical constructions, the perimeter
sections must be fitted with connection sealing made
from A1 or A2 fire reaction materials (for instance floor
strips Orsil N/PP). The perimeter sections must be
anchored using steel plugs Ø 6 mm (for example DN6 or
ZHOP) with 500 mm span.
■
Sheathing is carried out using two layers of Glasroc F
boards Ridurit with 20 mm thickness, the boards are
oriented horizontally. First sheathing layer is fixed with TN
212 screws in spacing 200mm to the support
construction. The boards are mounted to tight butt joints
without need of cementing. The second sheathing layer is
screwed to the first sheathing layer using screws Rodurit
in square net 250 mm. Reset of joints of the first and
second layer of Ridurit sheathing is set to 600 mm
vertically and 300 mm horizontally.
Assembly with support structure
■
Vertical intermediate R-CW sections are fixed in 1000 mm layout spacing between R-UW sections and vertical perimeter
R-CW sections.
Assembly without support structure
■
Maximum width of the shaft wall is 2 metres in this case (board length). Steel squares made from steel galvanized sheet
metal 40/20/1 mm are used as perimeter sections, they are anchored to bearing wall using Ø 6 mm steel plugs (for example
DN6 or ZHOP) with 500 mm spacing.

Rigips solution is shown here as an example. Alternatively it is possible to apply the
solution from Knauf or Promat. In such a case follow the instructions of the producer.
