Definitions

  • the present invention relates to a device for holding a Platform on a conical antenna mast, preferably made of reinforced concrete, the platform being a cylindrical inner pot surrounding the mast having.
  • the inner pot comprises the Platform the conical mast, leaving a relatively wide gap is poured with concrete to secure the platform to the mast. This is it required, the platform to be arranged mostly at high altitude above the ground during pouring and hardening of the concrete filling of the annular gap supported by a support device, which causes considerable problems. This also applies to conical vertical struts using rigid steel ring sleeves swing arm to be fastened, as described in DE 198 11 619 A1 are. There too the gap between the cuffs and the conical Wall poured out.
  • US 5,641,141 relates to a device for holding antennas on a conical mast with at least one mounting sleeve that is clamped to the mast.
  • the problem of the taper of the mast arises with this antenna attachment not because the weights to be caught are orders of magnitude smaller than in walkable platforms.
  • the invention is therefore based on the object of a fastening device in a simpler manner and without the provision of an auxiliary carrying device sufficient platform attachment for the platform on an antenna mast Find.
  • the invention provides that the platform is held between two circumferentially flexible clamping rings and is attached to the mast by means of the clamping rings. According to the invention, there is therefore no Pour out an inner annular gap of the inner pot of the platform, but this Inner pot is between the two circumferentially flexible clamping rings supported. Due to the flexible design of the clamping rings can in spite of their basically cylindrical shape, bend them so that they lay flat on the conical mast and thereby by accepting the corresponding conical shape beyond the pure clamping force a connection cause with the mast, which due to its expansion down a slide safely prevented even under heavy loads.
  • the clamping rings should consist of several, preferably three or more together screwed segments consist of those of the clamping screws enforced, preferably welded end plates of the segments welded support and stiffening plates can be braced.
  • This training makes it possible to directly on the mast, if necessary, before its installation or in the course of its manufacture, to fasten the lower clamping ring, so that the platform can then be moved using a crane or a helicopter can be placed on top of this clamping ring, which then by the mechanics already working on the platform with the help of the upper one Clamping rings can be fixed.
  • two can be the same Clamping rings are used or an education in which the lower Clamping ring has a slightly larger diameter than the upper clamping ring.
  • the platform can be connected to the clamping rings
  • brackets are provided at least on the lower clamping ring to screw on the inner pot of the platform stiffening against each other fixed by stiffening plates braced upper and lower washers are.
  • the platform radial support struts extending from the inner pot stiffened by the ring washers have, on which the, preferably grid-shaped platform floor attached is.
  • the further Training and division is preferably made so that the support struts as I-beams are formed and the support struts lying in the parting plane with their base webs are put together on U-beams.
  • connection of the two halves of the platform is then preferably carried out by the Parting plane of the platform parts flanking the inner pot halves and the Support strut halves of welded screw connection plates.
  • a platform 2 On the conical mast 1 shown only partially in the upper section in FIG. 1, which should preferably consist of reinforced concrete, is a platform 2 with the help of they attached under and overlapping clamping rings 3 and 4, this platform serves in the usual way as a carrier for antennas, but for better clarity are not shown in FIG. 1.
  • the radial support struts consisting of two halves screwed together 5 and 5a, 5b having platform 2 has a cylindrical inner pot 6 which by mutually braced by stiffening plates 7 lower and upper Ring discs 8 and 9 is stiffened.
  • the platform halves 2a and 2b are through Screw connection plates 10, 11 and 12 and screw connections passing through them 13, 14 and 15 connected together.
  • the screw connection plates 10 and 11 are arranged on the in the parting plane of the platform halves 2a, 2b welded support struts 5a and 5b, while the Screw connection plates 12 on the base legs of the divided support legs 5a, 5b, possibly also welded to them.
  • the clamping rings 3 and 4 are - at most with the minor exception that the upper clamping ring can have a slightly smaller diameter than that lower - of identical design, so that only one of these clamping rings in FIGS. 3 and 4, the lower clamping ring 3, is still shown in detail.
  • This clamp ring 3 consists of three screwed together segments 3a, 3b and 3c, the at their ends welded welded through by the clamping screws Wear end plates 17, two of which are adjacent to each other End plates of two segments 3a, 3b and 3c are screwed together. This End plates are welded to the support and stiffening plates 18 with the Braced ring segments.
  • the clamping rings are flexible in the circumferential direction trained so that they tight when tightening the fittings 16 and assuming the slight cone shape of the mast 1 on its outer circumference create, although they need not have a cone shape, but cylindrical could be.
  • brackets 19 for screwing on the platform, specially attached to the washers 8 and 9.
  • These brackets 19 include radial Vertical planar plate-shaped welded to the clamping rings Support elements 20 on which the bracket supports 21 attached, screwed in the present case.
  • Support elements 20 on which the bracket supports 21 attached, screwed in the present case.
  • the grid is finally trained, preferably from individual placed on the support struts 5, 5a, 5b Marked segments formed platform floor.
