Document Type and Number:
Japanese Patent JP2022057671
Kind Code:
A
Abstract:
To prevent the front end of an inner periphery sleeve member of a telescopic joint part from catching on a heat insulation material when two chimney units sandwiching the telescopic joint part of a chimney for a building are relatively displaced from each other.SOLUTION: A plurality of cylindrical chimney units 10 are jointly set in a chimney axial direction and supported on a building 1. An annular telescopic joint part 20 is laid between two chimney units 11, 12 neighboring each other in a mutually approachable/separable manner. The telescopic joint part 20 includes a soft heat insulation material 21, a flexible outer periphery cover 22, and an inner periphery sleeve 23. The inner periphery sleeve 23 has a pair of inner periphery sleeve members 31, 32 protruded from the opposed ends of the chimney units 11, 12, respectively, and placed over the inner periphery of the heat insulation material 21. At the opposed front ends of the inner periphery sleeve members 31, 32, inside inclined ends 35 are formed inclined to the inside of the chimney toward mating sides, respectively.SELECTED DRAWING: Figure 6
