Definitions

  • the present invention relates to a prefabricated chimney, or in other words to a chimney which is made from various elements manufactured in advance and constructed in such a way that they can easily be juxtaposed and connected one to the other on site, in order to form the chimney.
  • This chimney will preferably be applied for large chimneys, such as factory chimneys.
  • the prefabricated chimney according to the invention makes it possible to erect such a chimney in a minimum of time, so that the assembly costs can be kept at a relatively low level and that it becomes possible, according to the requirements and / or the desires, to erect either only the outer envelope, or the outer envelope together with its interior refractory covering.
  • connection between the various elements both vertically and horizontally, can be effected by a simple tightening of cables or of similar elements which are provided for this purpose through the various elements.
  • the prefabricated chimney according to the invention consists for this purpose, and at least for the construction of the outer envelope, by the combination of various superposed rows of elements themselves juxtaposed, preferably of reinforced concrete, these various elements being connected together and with the base of the chimney, both vertically and horizontally, by means of tensioning cables, rods or the like.
  • FIG. 1 there is shown a chimney 1 whose outer envelope consists of elements 2 of reinforced concrete, one of which is shown separately in Figures 2 to 6 and each of them being formed by means of a panel curved, whose radius corresponds to the half-diameter of the desired chimney and where this panel is provided in this case on its upper edge with a rib 3, while the lower edge is provided with a corresponding groove 4.
  • each element there are further provided two passages, respectively 5 and 6, the first part of the lower edge and spring for example in the left side edge of the panel, while the second part of the right side edge of the panel for spring shot in the upper edge.
  • the passages 5 and 6 are parallel to each other and their inclination relative to the lateral edges of the panel 2 will depend on the diameter and the height of the chimney, as will appear subsequently.
  • each panel 2 can be provided with a rib 7 and a groove 8 respectively, as shown schematically in the variant of FIG. 7.
  • such an element 2 will also be provided, preferably before mounting, with an appropriate insulating layer 9.
  • the lower and upper elements will also be provided with notches, respectively 14 and 15 which, as will appear in the following, serve to provide constraint devices, or respectively to have access thereto, while, depending on the height of the chimney, notches will also be provided, respectively 16 and 17, at levels such as for example AA and BB where, depending on the height of the construction, these levels AA, or respectively BB, or possibly others again, could be provided for example every 20 meters.
  • a next row of elements 2 is then put in place and so on until level AA is reached, and each time the grooves 4 of a given row of elements are made to cooperate with the ribs 3 of the underlying row of elements and the elements of each row are allowed to shift in such a way with respect to the elements of the previous row, that the passages 6 of one element are placed coaxially with the passages 5 of another element.
  • a cable 21 or similar element which will be connected in an appropriate and well known manner to the upper end of an anchor 19, each cable 21 being provided at its upper end with a tensioning device 22, in itself also well known, by means of which it is possible to put the cables 21 under the appropriate tension in order to obtain that all the superposed elements 2 are firmly tightened against each other both in the vertical direction and in the horizontal direction, so as to obtain a perfectly stable assembly.
  • FIGs 15 to 17 there is shown an alternative embodiment which will preferably be applied and where the elements 26 which form the outer envelope are made in a U shape, where the arms, respectively 27 and 28 of these U shapes are provided with mortises, or tenons respectively, 29 30 and 31 32 by means of which it is obtained that these elements can be placed very efficiently with respect to each other in the horizontal direction and connected to each other, while these elements will be provided in the vertical direction similar to that described above for elements 2, ribs 3 and grooves 4.
  • Each element 26 also has a layer of insulating material 33 and is connected to a panel 34 of refractory material, which will also be produced in approximate form. tive of a U and whose arms, respectively 35 and 36 adapt appropriately to the arms 27 and 28 of the external elements in order to obtain in any suitable manner a connection between the internal elements and the external elements.
  • cables 21, 23 and 24 will be used in the same way, when three sections are formed, in order to assemble the whole, although in the case of this latter embodiment.
  • the great advantage is obtained not only of making use of prefabricated elements which are suitably connected to one another by constraint cables both horizontally and vertically, but also that the inner and outer casing of the chimney are placed in a single phase .
  • annular closure plate 37 which closes the opening formed between the inner shell and the outer shell of the chimney.
