<p>A support (of metal or moulded plastics) for an elongate body (e.g. a pipe) passing through a hole in a wall, comprises an apertured plate (10) fixable to the wall and formed with a sleeve (18) surrounding the aperture and extending into the hole, the pipe passing through the aperture and sleeve and being held spaced from the inner surface of the hole by means (integrally formed lands (14) or a ring, or a ring fittable in the support). Supports are described having two or more apertures (12) with respective sleeves and bearing means, with areas readily broken away to allow formation of further apertures, which are of separable parts allowing fitment to an existing pipe run. Plates are said to be provided with volumes of intumescent material operable to seal the hole against fire, this material acting as the bearing means, or being a layer covering the face of the plate on the wall or as volume between said sleeves(s) and further sleeve(s) formed therearound. Arrangements are described for supporting elongate bodies (e.g. pipes, cables, cable trays...) passing through solid and cavity walls making use of the described supports as well as outer piping-, and intumescent material-sleeves extending between supports at opposite ends of a hole in a wall; as are methods of using the supports and other noted elements.</p> |
