摘要:
Embodiments of this application provide a composite structure of a cable and an auxiliary tool for wall penetration and a cable, and relate to the field of optical communications technologies. The composite structure of a cable and an auxiliary tool for wall penetration includes a traction member, a cable, and a guide pipe, where one end of the traction member is securely connected to the cable, a pipe hole of the guide pipe is used to allow the cable to pass therethrough, and a gap exists between an inner wall of the guide pipe and an outer wall of the cable.

A firestopping sleeve positionable usually in walls which is self-adjusting and includes a sleeve defining an access corridor extending longitudinally therewithin with at least one firestopping pad positioned therein. The sleeve has an access corridor extending therethrough for receiving wall penetrating cables which are firestopped therearound by the pad. A projecting block is attacked to the pad for providing self-adjusting and sealing capability of the device, to prevent air or smoke leaks around the cables.

The invention relates to a building-services unit (10), which includes a body component (12), a cover component (16) arranged to be attached to the body component in order to close the building-services unit, and inside which building-services unit elongated pieces (14) can be fitted. The cover component (16) includes edge bends (20) in the longitudinal direction (L) of the building-services unit, stiffening shaping (15) is fitted between the edge bends, and the building-services unit includes magnetic fastening (30) for attaching the cover component to the body component, which, when the building-services unit is assembled is in connection with at least one of the edge bends. The invention also relates to a building-services-unit system, a method for manufacturing a building-services unit, and the use of a building-services unit.
摘要:
Ein Kabelschutzrohrsystem (2), insbesondere für eine Hanglage, ist gebildet aus einer Mehrzahl von miteinander verbundenen Rohrelementen (5a, 5b, 5c, 5d, 5e) aus Kunststoff, welche einen durchgehenden Rohrkanal für eine oder mehrere Leitungen bilden, wobei der Rohrkanal einen Innendurchmesser von 45 mm bis 400 mm aufweist. Zur Kompensation von Umgebungsverschiebungen umfasst der Rohrkanal eine Mehrzahl von Kompensationselementen (6a, 6b, 6c), wobei ein jedes Kompensationselement als längenvariables Rohrsegment oder als teleskopierbares Rohrsegment ausgebildet ist. Ein zwischen zwei, an entgegengesetzten Seiten eines Kompensationselementes befindlichen, Stellen (8a, 8b) des Rohrkanals definierter Axialabstand (L1, L2) ist über eine Wirklänge (Lw) variierbar, wobei die Wirklänge mindestens 35 cm beträgt.
