Butt joint inserting type flue gas exhaust pipeline

Abstract

The invention discloses a butt joint inserting type flue gas exhaust pipeline. The butt joint inserting type flue gas exhaust pipeline comprises flue gas exhaust pipeline bodies which can be in butt joint with each other up and down; inserting structures in corresponding arrangement are arranged at the end parts of the upper end and the lower end of each section of the flue gas exhaust pipeline bodies; and the flue gas exhaust pipeline body located at the relatively upper portion and the adjacent flue gas exhaust pipeline body located at the lower portion are connected together in an inserted mode according to the inserting structures in corresponding arrangement at the end parts of the upper end and the lower end of the flue gas exhaust pipeline bodies. The flue gas exhaust pipeline bodies are inserted together according to the insertion structures in corresponding arrangement at the end parts of the upper end and lower end of the flue gas exhaust pipeline bodies, the direct butt joint parts of the upper and lower flue gas exhaust pipeline bodies can be located at any position of a floor, construction and installation are facilitated, and the construction efficiency is high. Therefore, the flue gas exhaust pipelines can be manufactured at the unified height regardless of the height of the floor; the height of a single-section flue gas exhaust pipeline is effectively reduced, the machining is facilitated, the production efficiency is improved, and the product quality is guaranteed; meanwhile, the hoisting and transportation are facilitated; and the flue gas exhaust pipeline cannot be easily broken in the hoisting and transportation process.

Description

technical field [0001] The invention relates to a butt plug-in type smoke exhaust pipe shared by buildings. Background technique [0002] Existing smoke exhaust pipes shared by buildings are generally square tubular structures. The smoke exhaust pipes of this structure are generally consistent with the height of the floor, and the height is generally more than 2.7 meters, which is limited by the existing processing technology and construction technology. , the direct butt joint of the upper and lower smoke exhaust pipes must be located in the plane of the floor. Since the overall height of the single-section smoke exhaust pipe is too high, and the building heights of different buildings are inconsistent, the single-section smoke exhaust pipe can only be made manually. operation, its production efficiency is low, and at the same time, because the exhaust gas pipe is a thin-walled cement product, the product yield and product quality are difficult to guarantee, and because the...

[0002] Existing smoke exhaust pipes shared by buildings are generally square tubular structures. The smoke exhaust pipes of this structure are generally consistent with the height of the floor, and the height is generally more than 2.7 meters, which is limited by the existing processing technology and construction technology. , the direct butt joint of the upper and lower smoke exhaust pipes must be located in the plane of the floor. Since the overall height of the single-section smoke exhaust pipe is too high, and the building heights of different buildings are inconsistent, the single-section smoke exhaust pipe can only be made manually. operation, its production efficiency is low, and at the same time, because the exhaust gas pipe is a thin-walled cement product, the product yield and product quality are difficult to guarantee, and because the single-section smoke exhaust pipe is too high as a whole, it is not convenient for hoisting, transportation, construction and installation, construction low efficiency
