Ventilation element, e.g. electrical switching or voltage converting station integrated in outer wall of building - has transverse sections extending to each other between side cheeks which respectively have section surfaces inclined between two longitudinal webs

The two longitudinal webs (42,44,44n) run parallel in front and rear regions. A material strip, having a perforated metal sheet (62) or similar recesses, is arranged respectively between the upper longitudinal web of a transverse section (24,24n) and the lower longitudinal web of an adjacent transve...

Beschreibung
Zusammenfassung:	The two longitudinal webs (42,44,44n) run parallel in front and rear regions. A material strip, having a perforated metal sheet (62) or similar recesses, is arranged respectively between the upper longitudinal web of a transverse section (24,24n) and the lower longitudinal web of an adjacent transverse section. An anchor hollow section (34), with a cross-sectional part circular anchor slot (35), is formed from the rear longitudinal web (42,44,44n) of the transverse section (24,24n) above the inclined section surface (56). The anchor slot (35), with a contact surface (52) of the section surface, forms a push in slot for the material strips (62). ADVANTAGE - Simplifies construction of ventilation element. Accelerates prodn. throughput and improves operational safety and reliability.
