'[Also in Divisions F2 and A4] A combined clip and stand for a pipe 13 has mating parts 29, 30 which provide for relative adjustment between them and thereby in use adjustment of the effective height of the combined clip and stand relative to a support from which the stand is mounted, the stand having a split hollow collet-like anchoring sleeve 32, for insertion in said support and a plug 34 for forcing the sleeve against the sides of the hole thereby to anchor said clip and stand. In the construction shown the socket part consists of two oppositely disposed arcuate wings 29 formed integrally with the clip 26, the wings together forming a tubular stem for the clip 26 which is annular except for diametrically opposite gaps 27; the gaps enable the clip resiliently to grip the pipe. The spigot part 30 of the stand is hollow and is formed with the sleeve 32 which has a central liner 33. Both the socket part and the spigot part are formed with circumferential interfitting teeth 36 which provide the mating parts and the means for contracting the sooket part is a tapered lock nut 37 which engages a tapered thread 38 provided by the socket part. The clip can be formed with a circumferential stiffening rib. A combination of the clip and stand with a pipe having an expansion joint is described the expansion joint including a sleeve supported by the clip the sleeve having a locating boss or rib positioned in one or both gaps of the clip.</p> |
