1 -- Housing of the ERK-MB (50 mm thick)
2 -- Blade dampers (parallel; 40 mm thick)
3 -- Transmission rod of the blade dampers
4 -- Actuator
5 -- Housing of the actuator and transmission rod
incl. inspection cover
6 -- Hexagon screws with shaft similar to DIN 931
(ISO 4014) M8 x 100 mm
7 -- U-washers to DIN 125 (ISO 7089)
int. Ø 8.4 / out. Ø 16 / 1.6 mm thick
8 -- Drive-in nut M8 with 4 prongs (galvanized steel)
d2 = 22, d3 = 10, h = 15. The drive-in nut must
be flush with the housing side.
9 -- Insulfrax paper 5 mm thick glued with waterglass glue.
10 -- Housing ERK-MB-V
11 -- Mortar of category M10 to EN 998-2 (previously: MG III
according to DIN 1053) or fire protection mortar of sui
table grades; gap ≥ 10 to ≤ 50 mm.
12 -- Mounting bracket type WE-S (galvanised steel
100 x 100 x 160 mm long)
13 -- Hexagon head screw to DIN 931 (e.g. M 10 x 30 mm)
14 -- U-washers DIN 125-A
15 -- Fire safety dowels, e.g. type KMU-F10 (for reinforced
concrete walls only)
16 -- Profile UW 50/40/0.6 (for wall thickness = 100 mm, for
larger wall thicknesses, the profiles must be
adapted accordingly)
17 -- Profile CW 50/50/0.6 (for wall thickness = 100 mm, for
larger wall thicknesses, the profiles must be
adapted accordingly)
18 – Mineral wool (non-flammable according to EN13501-1, ap
parent density ≥ 100 kg/m³, melting point ≥ 1000 °C, min.
thickness according to the actual gap dimension.
Insert the mineral wool over the entire profile web height.
19 -- Wall panelling (on both sides, double)
20 -- Universal screw, for example 4.0 x 50 mm, distance
a ≤ 250 mm or min. distance, but 2 screws per side
21 -- Smoke extraction duct (in accordance with EN 12101-7, tested
according to EN 1366-8)
22 -- ERK-MB suspension
22.1 – Suspension of the smoke extraction duct, taking into
account the maximum suspension distances, may be
not required
23 -- Security grille type ASG-E
24 -- Coarse thread screw ≥ 3.9 × 45, distance ≈ 100 mm
25 -- Waterglass-based adhesive
(shown with dashed lines) - on site
26 -- Sleeve connection (width 100 mm, thickness 20 mm)
with fastening material (coarse thread screw
≥ 3.9 × 45, distance ≈ 100 mm) - on site
27 -- Solid ceiling
28 -- Fire safety dowel (see p. 19)
29 -- E90 or E30 cable connection and cable routing
according to DIN 4102-12
30 -- Solid smoke extraction shafts made of solid building ma
terials (e.g. concrete)
31 -- Seal the circumferential gap of at least 20 mm with
mortar of group II or III, DIN 1053 or with
concrete
