J PR sr I A ΠON OF THE ESSENCE OF THE INVENTION
1 hi. essence of the invention lelates to pioduction of piefabπcated chimney element of baked teira cotta with oi without addition of gionnd tena cotta and/oi fiie clay in the mixture, which is extruded The elements are produced in variants being of internal O ol flue 10 and 1 cm and for each 0 external dimensions of the element's height vary so that six elements aie pioduced in lotil being ol dimensions 14x25x18 cm, 19x2^x 8 cm 24x25x18 cm Each individual element has two mutually iniegiated parts (D ,\w ni" I 4) of which one is a chimney flue and the other is a stiuctuial connection to standard elements of the wall on the light and on the left in lelation to the axial chimney flue line Method of building in of pre fabi icated chimney flue elements is obvious 11 m ihe Diawmg 5 Six dimension vanants of the elements ensure combination with all types of standard elements being used in hi_.fl use cυnstiυction Besides obtaining of high level of construction strength of a chimney, savings in eonstiuction costs aie achicsed SIIORI DES RIPTION Ol" DRAWINGS

6 Dl SCRIPT ION OF THE METHOD OF PATENT REALIZATION
\s loi the indiistnal aspect the invention can be completed on usual extruders (presses) foi pioduction of peifoiated buck pioclucts using special tools foi dimensioning purposes and profiling necessary holes Piepaiation of mixtuie foi extiusion is possible to combine with giound teπa cotta an/oi fii e-clay powder as a supplement to increase mechanical hardness and insulaimg leatuies \lieι the extiusion diy mg and baking, a pi efabi icated chimney element as a product is palletized, packed and labeled in compliance with common piocedutes in buck industry
7 MLTIIOD Or INVENTION APPLICATION
Kcadv made pioduα a ptefabticated chimney element, is built in 'in situ', dnectly into a wall in a position foieseεn by a pi ieu design in such a mannei that those parts deteimined to serve as a bond with a wall, make a compact connection with the wall as show ι on the diawmg No 5 Vai ions height dimensions of individual prefabricated chimney elements give a possibility to build the
ele enl into the walls, which are made of bπcks (blocks, elements) of sundry standard dimensions In the coui se of bui lding-m the chi mney elements, necessai y holes for building in a chimney access doors and rosettes for installation of fume pipe ai e immediately made
