Definitions

  • the invention relates to a reinforcement anchor on a wall is attached and the reinforcement one on the wall applied refractory lining (coating) is used.
  • a reinforcement anchor is already known from document US-A-4 763 584.
  • the newly developed reinforcement anchor is special for the attachment to so-called fin tube walls.
  • Fin tube walls are analogous to FIG. 1 (prior art) built up. They consist of tubular elements 10 (hereinafter referred to as pipes) and the pipes 10 connecting Surface sections 12. While one side of the fin tube wall is covered by a refractory lining 14, on insulation on the other side Mineral wool must be applied.
  • tubular elements 10 hereinafter referred to as pipes
  • refractory lining 14 While one side of the fin tube wall is covered by a refractory lining 14, on insulation on the other side Mineral wool must be applied.
  • Such fin tube walls are used in Power plants, waste incineration plants or the like.
  • the shaft anchors run exclusively in the axial direction of the Tubes 10 ( Figure 2, right representation) and are only through To fix hand welding. Such a process is for one is complex and the other is not optimal Reinforcing effect for the refractory lining 14.
  • the slot pins are identified as 16a in FIG also by hand welding onto the surface sections 12 welded on and then with a wedge along a central one Slot divided in the axial direction, as by the reference numeral 16b indicated.
  • the disadvantage here is that for Reinforcement function important free end areas of the Reinforcement anchor 16 has a very small cross-sectional area have and accordingly do not absorb high loads can.
  • the cross-sectional area of the angled free End areas of the slot pins is only about 30% of the Cross-sectional area of the slot pins at the weld, since also the axial slot (before bending) already material takes away.
  • the object of the invention is to provide a reinforcement anchor mentioned type, especially for use Fin tube walls, to provide the avoids the aforementioned disadvantages, in particular easily assembled and can absorb great forces.
  • the invention is based on the knowledge that a appropriate reinforcement anchor must be designed so that it with the help of a stud welding technique on the above Surface sections between the pipes can be attached a largely constant material thickness over its has entire longitudinal extent and shaped at the same time is that it is the most critical for the reinforcement function Covering the area around the pipes.
  • the reinforcement anchor which is preferably in one piece (one piece) is thus essentially comprised of two sections are designed differently and have different functions fulfill.
  • the U- or V-shaped base part is used for attachment on the fin tube wall, in the area of the entrance mentioned surface sections between adjacent pipes. This done by stud welding, preferably by means of Arc. In this procedure, there is a gap between the base part and on the short side of the metal wall an arc of high current ignited. The arc melts both parts, the parts are put together and the power is turned off.
  • the process can be carried out using drawn ignition (DVS leaflet 0902) as well as with tip ignition (DVS leaflet 0903).
  • one more or less point weld connection to the wall In the case of a V-shaped base part, one more or less point weld connection to the wall. In the case of one U-shaped base part is more or less linear or rectangular welded connection to the wall.
  • Welding aid an adapter in which the armature anchor in front of the Welding process is aligned and held
  • the orientation of the anchor usually be such that the plane spanned by the legs of the base part parallel for the longitudinal extension of the pipes and perpendicular to the wall, as shown in the following description of the figures is.
  • the arms extend accordingly (both vertically and also viewed parallel to the wall) at a certain angle, which should be greater than 0 but less than 90 °.
  • the arms are not perpendicular to the Axial direction of the pipes, but at a certain angle starting from the connection area to the base part, rising slightly (i.e. according to the shape of the neighboring pipes).
  • the base part has a V-shape ( Figure 5) and which is designed S-shaped in the top view, preferably with an elongated S-shape ".
  • the reinforcement anchor can avoid as much as possible at least partially covering its surface with a melting or burning out under the influence of temperature Own material.
  • This cover can, for example, in the form of Plastic caps are made on the free ends of the arms be plugged on.
  • the cover can also be made from a Arms fully or partially covering Plastic coating exist that under the influence of temperature (under conditions of use) melts and so - like that called caps - a space between the reinforcement anchor and the refractory lining creates the thermal one Compensates for changes in length.
  • the invention is based on a Embodiment described in more detail.
  • Figures 4a, 4b and 4c show an inventive Reinforcement anchors in different views, each strong schematized.
  • Figure 4a can be the one already known from Figures 1 to 3 remove the basic structure of a fin tube wall.
  • FIG. 4c shows the welding aid 18 used for this with a receiving opening 20 for assembling the armature 16 and a chamber 22 formed on the underside into which the tip end 16s of the V-shaped base part 16v of the armature 16 protrudes.
  • the armature 16 can be used for arc welding be held securely between adjacent tubes 10.
  • At the A welding process forms in the chamber 22 Protective gas atmosphere that supports the welding process.
  • a variety of anchors 16 are placed on the fin tube wall welded on and there is then an arrangement as in Figure 4b shown.
  • the arms 24 of the reinforcement anchor 16 Connect materially to the V-shaped base part 16v.
  • the arms 24 each extend at an angle ⁇ of approx. 45 ° to the plane spanned by the V-shaped base part 16v E1.
  • the arms 24 are angled, here in each case an angle ⁇ of approximately 55 °.
  • FIGS. 5 and 6 The shape of the anchor is shown in FIGS. 5 and 6 in exemplary version with V-shaped base part 16v (Figure 5) and U-shaped base part ( Figure 6) and twice angled arms 24 with attached at the end Plastic caps 26.
