Definitions

  • the present invention relates to the field of post or pole installation, particularly although not exclusively to the installation of posts for street furniture, eg. traffic light posts, pedestrian rail posts or the like.
  • a common method of installing a conventional post is to dig a hole in the ground at an installation site of the post, insert a base of the post into the hole and fill the space between the post and the side walls of the hole with concrete.
  • the concrete sets, to rigidly fix the post in the hole at the installation site.
  • an anchor bar laterally extending to the length of the post bar may be fitted through a lower end of the post prior to inserting the lower end in the hole, such that when the concrete sets around the lower end, the laterally extending bar prevents rotation of the post in the concrete.
  • a post housing for ground installation of a post, the post housing comprising a tubular sleeve for receiving the post, the sleeve having a portion adapted to releasably secure the post.
  • a base portion of the sleeve is adapted to releasably secure a lower end of the post.

  • the base portion may comprise a collar, a surface of which is tapered inwardly towards a lower end of the base.
  • An internal width of the tapered portion of the collar may be selected so as to closely coincide with an outside diameter or width of a corresponding post to be fitted into the sleeve.
  • the post may be driven downwardly in order to jam the lower end of the post into the inwardly tapered collar portion, which grips the lower end of the post to resist removal of the post in an upward axial direction, and to resist rotation of the post about a main central axis of the post.
  • the post housing may comprise a compression means, eg. a ring, adapted to fit to the collar portion.
  • a compression means eg. a ring
  • the ring is of metal construction.
  • the compression ring is provided with a locating means, in the form of one or a plurality of peripheral grooves, for locating the ring to the collar.
  • This may have an advantage of strengthening the lower collar portion of the post to prevent splitting of the collar under driving of the post into the collar by force.
  • the post housing has at an upper end thereof, a post centralising means, for aligning the post co-axially with the sleeve.
  • the post centralising means may comprise a ring adapted to fit into an upper rim portion of the sleeve.
  • the ring is preferably formed into the sleeve such that the plastics material of the sleeve surrounds the ring.
  • the sleeve material is interposed between the post and the ring.

  • the tubular sleeve is formed of a plastics material, which may be polyethylene.
  • the reinforcement member may be a ring, eg. a steel ring.
  • the tubular sleeve may be formed in a two piece mould, which is rotationally spun in order to form the tubular sleeve. Rotational spin forming of the tubular sleeve may provided a relatively quick method of formation of a post housing, and thereby enable a significant cost reduction.

  • the sleeve 150 has a side aperture 151 defined by an integrally moulded tube 152 which projects at an angle inclined to the longitudinal axis of the sleeve 150.
  • the presence of the tube 152 facilitates the threading of cables into a post secured within the sleeve. Because of the way in which the tube 152 is angled, cables which are pushed into the aperture 151 will tend to be guided into the oval slot shown in the tube in Figure 8, in such a way that the cables tend to travel upwardly within the post. This is particularly convenient when the post is intended to carry traffic light signals.
  • the sleeve 150 is moulded in such a way as to provide an inwardly projecting rib 153.
  • the slot in the post can be arranged so that it is in register with the projection 153 which then locates in the slot. This then prevents any tendency for the post to rotate within the sleeve. Rotation of the post in its mounting can be highly undesirable, particularly in the case of traffic lights.
  • the lower part of the sleeve 150 is moulded so as to have a substantial flange 154.
  • the sleeve shown in Figure 15 has a metal reinforcing ring 155 completely embedded in the plastics material 156 from which the sleeve is moulded. This substantially reduces or eliminates any tendency for the reinforcing ring to corrode, even in the extreme conditions encountered in use.
  • FIG. 15 Another innovation of the embodiment shown in Figure 15 is that an integral bung 157 is moulded with the sleeve. This bung is then separated from the sleeve by cutting and can be subsequently used to plug the upper end of the sleeve prior to insertion of a post. This means, for example, that if there has to be a time delay between securing the sleeve in the ground, and inserting a post, the sleeve does not become filled with water or dirt.
  • Figure 16 illustrates a further embodiment which makes it possible to use one size of sleeve to accommodate different diameters of pole.
  • the diameter of the plug 158 can readily be varied during moulding by adjusting the size of part of the moulding core.
  • Figure 16 illustrates an embodiment in which an intermediate adaptor 159 is provided to take up the space between the sleeve 150 and a pole 160.
  • Figures 17a and 17b illustrate an alternative embodiment of adaptor 159 which is adjustable.
  • the adaptor comprises an annular member which is split on location 161. A bolt 162 can be screwed into the split to expand it. the widening of the split causes the adaptor 159 to be compressed between the post 160 and the sleeve 150 thus making the post even more secure in the sleeve.
  • Figures 18a and 18b illustrate the use of a reinforcing ring 163 that has a plurality of radially extending holes 164 spaced about the periphery thereof.
  • plastics material 165 flows into the hole to assist in securing the reinforcing ring in position.
  • Figures 19a and 19b show a similar arrangement, except that the apertured reinforcing ring 163 is spaced inwardly from the outer periphery of the sleeve whereas the reinforcing ring shown in Figures 18a and 18b is positioned on the periphery sleeve.
  • FIGs 20a and 20b there is illustrated yet another embodiment of reinforcing ring 166 which is similar to the ring shown in Figures 19a and 19b except that the holes 164 project in the axially direction rather than the radial direction.
  • the locking member shown in Figures 21 to 23, comprises a tapered bung 167 which has a circular cross-section except for a square cross-section socket 168 in the base of the bung.
  • the bung is arranged to cooperate with a sleeve which is generally similar to the sleeves shown in the earlier Figures except that the base of the sleeve is provided with an upstanding square cross-section spigot 169.
  • This spigot 169 is shaped to fit closely within the square section socket 168 of the bung 167.
  • the bung 167 is first hammered into the base of a post 170. Because of the tapered shape of the bung, hammering it into the base of the post 170 causes the bung to be very tightly locked within the post so that there is virtually no possibility of the bung being able to rotate with respect to the post.
  • the post with the bung inserted therein, is then fitted securely within the sleeve.
  • the engagement of the spigot 169 with the socket 168 ensures that the bung (and hence the post coupled thereto) cannot rotate with respect to the sleeve.
  • a tapered adaptor ring 200 is used to provide further grip between a pole 201 and a sleeve 202.
  • a reinforcing ring 203 may be located in the ring ( Figure 24) or the sleeve ( Figure 25).

Abstract

Logement de poteau, destiné à l'installation dans le sol d'un poteau, comprenant un manchon (150) tubulaire servant à loger le poteau, ce manchon étant doté d'une portion (158) conçue pour assujettir de façon détachable le poteau. Dans certains modes de réalisation, les moyens de fixation du poteau de manière détachable sont solidaires du manchon. Dans d'autres modes de réalisation, on peut utiliser une bonde (167) séparée, coincée dans le manchon afin d'empêcher la rotation du poteau. Ce logement constitue un moyen hautement efficace pour ériger des poteaux tels que des poteaux de feux de circulation, et il facilite leur remplacement lorsque ceux-ci sont, par exemple, endommagés par un accident de la circulation.
