#CMT# #/CMT# The conduit has a covering device comprising attachments to maintain a strip (2) i.e. thermally insulating strip, in wrapping position. The strip has two series (7, 8) of anchoring or hooking points (9) adjoining visible and masked longitudinal edges (4, 5) of the strip. The series of the anchoring or hooking points are arranged to extend on both sides of the visible longitudinal edge at rolled state of the strip in the position around a tubular body (1). Each attachment connects the anchoring or hooking points of the series in the position by spanning the visible longitudinal edge. #CMT# : #/CMT# The thermally insulating strip is in the form of two layers of glass fabrics and sheets based on alkaline earth silicate fibers that are interposed between the layers. #CMT#USE : #/CMT# Retrofit smoke evacuation conduit for use in existing evacuation conduit used in walls of building i.e. old house. #CMT#ADVANTAGE : #/CMT# The design of the retrofit smoke evacuation conduit avoids intervention on outdated existing conduit so as to avoid cost and inconvenience for habitants of building to destruct the portion of the building for repair or replacement. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a retrofit smoke evacuation conduit during closing of covering strip of tubular body by attachments. 1 : Tubular body 2 : Strip 4 : Visible longitudinal edge 5 : Masked longitudinal edge 7, 8 : Series of anchoring or hooking points 9 : Anchoring or hooking points. |
