  • FIGURE 4 is a partial longitudinal section on line IV-IV in FIGURE 3;
  • FIGURE 5 is a partial plan view of a bottom portion
  • FIGURE 6 is a perspective view of a cover section
  • FIGURE 7 on a larger scale is a detail section of a joint between two elements.
  • FIGURE 1 diagrammatically shows part of a house comprising a flooring 1 and a roof structure 2.
  • a boiler 3 having a boiler outlet socket 4 is diagrammatically shown in said house.
  • a chimney structure extends from the socket 4 through the flooring 1 and the roof structure 2 to a suitable height above said roof structure.
  • the chimney structure comprises a smoke flue 5 which is supported on the boiler outlet socket 4.
  • a smoke flue 5 Surrounding the smoke flue S is a first or inner jacket 6 and a second or outer jacket 7.
  • the inner jacket 6 and the outer jacket 7 are divided into a suitable number of elements 8 which are placed on top of each other and are closed by means of a cover 9.
  • the elements '8 are supported by a supporting structure 10 which is placed on the flooring 1 and consists of T-irons 11 and a bottom portion 12. Said bottom portion 12 closes the space between the inner jacket 6 and the outer jacket 7.
  • the inner jacket 6 is extended from the supporting structure 10 to the boiler outlet socket 4 with the aid of a section 13 which is insertable from below into the inner jacket 6 and which at the lower end is bent inwardly towards the smoke flue 5 or has a bottom portion.
  • the element 8 extending through the roof structure has a sheet lead envelope 14 for sealing the joint between the roof structure 2 and the chimney structure. Moreover, a sheet lead envelope 15 is provided between the smoke flue and the cover 9 for sealing the joint between them and for taking up heat expansion movements between them.
  • the joint between the boiler outlet socket 4 and the smoke flue 5 is sealed in any conventional manner, for instance by means of a toe portion as in FIG. 1.
  • the smoke flue is heat insulated from its environment by heat insulating material 16 which fills out the space between the smoke flue 5 and the inner jacket 6.
  • the heat insulating material 16 preferably consists of particles of burnt expanded clay.
  • Each element has an outer jacket 7 and an inner jacket 6.
  • Angle irons 17 are provided in each element both at the upper and the lower ends thereof.
  • the outer jacket 7 is of square cross section
  • the inner jacket 6 also is of square cross section but is turned through an eighth of a revolution relative to the outer jacket and is secured to it at the corners substantially along the longitudinal side median line of the outer jacket.
  • the corners of the inner jacket 6 are extended towards the outer jacket 7 being preferably formed of separate sheets for the sides meeting at the corners thence extending to jacket 7, and are each provided with a flange 18 by which the inner jacket is secured, preferably welded, to the outer jacket. This corner design is shown more in detail in FIGURE 3.
  • Each element thus has a smoke flue and four ventilation air ducts which shall all be separated from each other.
  • This guide means 25 also serves to guide the different superimposed elements 8.
  • the guide means comprises male portion 26 and female portion 27. Guide means of this type are arranged at each corner of the inner jacket in each element and in the bottom portion 12.
  • the bottom portion comprises four identical parts 19 (FIGURE 5) closing the ventilation air ducts.
  • the dotted line indicates a hole to be provided for the connection of a ventilation air pipe. Similar holes can be provided also in the outer walls of the elements.
  • the bottom portion thus comprises four identical parts 19 which are supported by the T-irons 11.
  • FIGURE 6 shows a perspective view of a cover 9.
  • This cover has an outer casing which extends from the smoke flue 5 outwardly over the outer jacket.
  • the cover 9 includes a part 6a covering the inner jacket 6 and having its corners extended outwardly over an outer jacket member 7a which projects into the corner walls 21 through slots therein.
  • the corner walls 21 serve to define the ventilation air ducts formed between the inner jacket 6 and the outer jacket 7.
  • a sheet lead envelope 15 is provided between the smoke flue 5 and the casing 20. Said envelope 15 is for sealing the joint and for taking up heat expansion movements between the smoke flue 5 and the cover 9.
  • snap means are provided between elements 8, between the uppermost element and the cover 9 and between the lowermost element and the bottom portion 12, as will be seen from FIGURE 7.
  • Downwardly directed eyelid openings are provided in the angle irons 17 and the jacket wall is bent outwardly at 24 to form between the angle irons 17 and the jacket wall 24 a suflicient space for the jacket wall of another element in which there is an eyelid opening corresponding to the eyelid opening 23.
  • the member 13 For mounting the chimney structure the member 13 is first placed in position whereupon the supporting structure 10 is placed upon the first flooring 1. Then a first element 8 is fitted to the bottom portion and on top of said element a further number of requisite elements up to the roof structure 2. The element extending through the roof structure 2 shall have a sheet lead envelope 14. A further number of requisite elements -8 are then placed on top of the element having the sheet lead envelope. Being allwelded from stainless acid-resistant sheet metal, the smoke flue 5 can now be inserted in the smoke gas duct formed by the inner jacket 6 until it rests on the boiler outlet socket 4. Now the member 13 is pushed up into the smoke gas duct and the joint between the socket 4 and the smoke flue 5 is sealed.
  • the cross section of for instance the inner jacket may be hexagonal while that of the outer jacket is square. Also with such a modification of the cross section of the inner jacket the diagonals thereof will be approximately equally long as the sides of the cross section of the outer jacket.
  • the supporting structure including the bottom portion 12 may be integral with the lowermost element 8 of the chimney structure.
  • a vertical chimney structure comprising a plurality of end-to-end, aligned, connected, prefabricated sections, each section including an outer rectangular and inner rectangular jacket each corner of the inner jacket being spaced inwardly from a corresponding side wall of the outer jacket, said inner jacket including outwardly projecting flanges at each corner thereof, said flanges extending from the inner jacket corners to the respective side walls intermediate a pair of adjacent corners of the outer jacket for maintaining the jackets in spaced relation, a tubular flue pipe disposed within the inner jacket and extending throughout the aligned sections, said pipe being spaced inwardly of the inner jacket walls, particulate insulation materials filling the space between said pipe and said inner jacket, and closure means at the end of the lowermost section closing the space between said pipe and said inner jacket.
  • closure means closing the space between the pipe and inner jacket extends downwardly from said base supporting the lower end of the outer jacket to substantially the lower end of said pipe the space therein exterior to the pipe being filled with material for insulating the pipe below said base.
  • said inner jacket being fabricated of four like sections each comprising a vertical flange extending inwardly from the middle portion of one side of the outer jacket thence diagonally across an adjacent comer of the outer jacket to form a side of the inner jacket, thence outwardly to a middle portion of an adjacent side, the four sections being juxtaposed with the respective diagonals thereof forming a square inner jacket rotated about 45 with respect to said outer jacket.
  • a structure according to claim 1 including lifting flange means on one end of each section for a positioning juxtaposed section ends, and detent portions in the flange and nested section ends comprising means for locking the two sections together when fully nested.
  • the vertical chimney structure comprising a plurality of end-to-end aligned, connected, prefabricated sections of which each section includes an outer polygonal jacket and an inner polygonal jacket comprising faces formed from a sheet outwardly turned at corners of the inner jacket to form lateral flanges extending to engagement with the outer jacket, contiguous flanges of adjacent inner jacket faces being positioned in parallel relationship as a common wall separating ventilation ducts exterior to respective inner jacket faces within said outer jacket, a continuous smoke flue disposed within the aligned inner jackets supported at a lower end thereof and spaced therefrom to provide insulation space between the inner jacket and smoke flue, a closure member at the bottom of the inner jacket to form a retainer for particulate insulation about the flue, a body of particulate insulation filling the space above the retainer, and means supporting said inner and outer jackets independently of support for said flue.
