Definitions

  • the invention relates to an anchoring device for stone slab covering stone slabs.
  • Boilers and furnace rooms require a fire-resistant wall construction in order to separate the boiler room from pipe units.
  • the tubular steel units are protected by walling or by hanging stone slabs.
  • the protection of the steel tube aggregates by hanging stone slabs has largely prevailed in industrial furnace construction. These are placed over a large area on the tubular steel units and the gaps are shed. In the event of malfunctions such as B. leakage or maintenance work, the plates were difficult to solve, so that mostly large areas had to be replaced.
  • the tubes of the tube assembly are connected to one another by means of tube fins, which were used to vertically weld a web to these tube fins, onto which a crossbar was in turn placed and locked with a split pin.
  • a disadvantage of such anchors is that the vertical weld guide is difficult to attach.
  • the main disadvantage is that the open plate surfaces compact with the sealing compound Need to become. This casting compound is naturally subject to poorer properties than the fired stone of the curtain stone slabs. Since the potting compound is subject to greater wear and thus blows off, the anchors are exposed to the combustion chamber without protection.
  • the present invention is therefore based on the object of providing an anchoring device with which it is possible to clad the pipe assemblies with stone slabs in such a way that the smallest possible area of casting compound indicates to the combustion chamber, since the invention is based on the knowledge that this casting compound is a weak point in terms of wear; i.e. the mortar is more porous than the fired stone and therefore tends to erode and crack off quickly.
  • the anchoring device for such steel tube aggregates covering stone slabs providing that an anchoring element consists of a tab arranged horizontally on the tube fin with a through-hole passing through it Receiving through hole leading stone holder, wherein the tab forming the anchoring element and the stone holder engages in the recess of the stone slab or in the gap between two stone slabs and are embedded covering the stone slabs.
  • this tab protrudes trapezoidally into the recess in the stone slab, in a special embodiment of the invention the stone holder has an angled design.
  • This inventive design of the anchoring device ensures that good elimination of welding is achieved by eliminating the vertical web on the tubular fin, as is the case in the prior art, and by using a horizontal web according to the invention.
  • the web to be slipped over for mounting is eliminated, as is the split pin required in the known devices. Both parts are replaced by a preferably curved stone holder.
  • the anchoring With the anchoring according to the invention, it is possible to mount the plates which are not recessed in the area but only in the area of the anchoring, the locking being carried out when attaching.
  • the plate is applied to the pipe system using mortar.
  • the plate is slotted and locked in the front area where the holding part is installed. Then the cut part is filled with potting compound.
  • the rapid progress of the present invention lies in the fact that the holder opening according to the prior art is avoided and therefore no longer has to be filled with casting compound, so that the entire surface, with the exception of narrow joints, can thus be found as a fired stone. This is particularly important because a fired stone does not have as much slag adhesion as is the case with the casting compound. The area of the casting compound pointing towards the combustion chamber is thus minimized.
  • the steel tube unit 1 has so-called tube fins 2 between the individual tubes.
  • the stone slabs 7 are hung in front of this tubular steel unit 1.
  • respective tabs 3 are welded horizontally to the tube fins 2, which are preferably trapezoidal.
  • the tab 3 has a through hole 4 for receiving a stone holder 5, which is preferably angled.
  • the tab 3 forming the anchoring element and the stone holder 5 engage in the recess 6 of the stone plate 7 or in the gap 8 between two stone plates 7 and are embedded in a covering manner by the stone plate 7.
  • the recesses 6, the gap 8, the joints 9 and 10 are pressed with potting compound 11.
  • potting compound 2 is introduced into the space 12 between the stone slab 7 and the tube fin.
  • an anchoring device for stone slabs covering stone slabs is created, with which it is possible to exclude the mounting openings of the stone slabs so that they no longer have to be present.
  • the entire surface can be found as a fired stone, thus minimizing the area of the casting compound pointing towards the combustion chamber.
