Problems solved by technology

[0002] At present, small and medium-sized self-supporting steel chimneys generally adopt factory prefabricated construction site installation. According to the existing transportation conditions and hoisting conditions, the prefabricated length of steel chimneys in the factory is generally 10m to 18m. If the inner cylinder needs to be installed in the outer cylinder, The production and installation process is more difficult

Embodiment

[0026] Embodiment: a kind of inner and outer cylinder type self-supporting steel chimney, as figure 1 As shown, it is composed of a carbon steel outer cylinder 1 and two stainless steel inner cylinders 2. The carbon steel outer cylinder 1 has a diameter of 2300mm and a height of 48500mm, and the stainless steel inner cylinder 2 has diameters of Φ800mm and 1100mm respectively. The height is 50000mm, that is, the top of the stainless steel inner cylinder 2 is 1500mm higher than the top of the carbon steel outer cylinder 1. Both the carbon steel outer cylinder 1 and the stainless steel inner cylinder 2 are composed of three sections.

[0027] Such as figure 2 As shown, at a height of 3000 mm from the bottom of the base flange of the lower carbon steel outer cylinder 101, reinforcements such as steel support bottom plate 3 and support channel steel 4 are used to weld and fix the lower carbon steel outer cylinder 101, and the bottom of the lower stainless steel inner cylinder 201...

Abstract

The invention discloses an inner and outer barrel type free-standing steel chimney, which comprises a carbon steel outer barrel and a stainless steel inner barrel arranged in the carbon steel outer barrel, wherein the carbon steel outer barrel and the stainless steel inner barrel consist of a plurality of subsections; the bottom of the lower stainless steel inner barrel is fixedly connected with the lower carbon steel outer barrel through a reinforcement piece; the top of the lower stainless steel inner barrel and the top of the middle stainless steel inner barrel are connected with the carbon steel outer barrel through a transverse-fixed longitudinal-sliding structure respectively; the top of the upper stainless steel inner barrel is connected with the top of the upper carbon steel outerbarrel through an upper limit structure; the top of the middle stainless steel inner barrel is provided with a middle limit structure; and the subsections of the stainless steel inner barrel are connected through a loose flange. The dead weight of the stainless steel inner barrel is borne through the reinforcement piece, the top of the stainless steel inner barrel is transversely fixed with the carbon steel outer barrel through the special structure to ensure that the stainless steel inner barrel does not sway, and the stainless steel inner barrel can slide in the longitudinal direction, so the free-standing steel chimney has the advantages of simple and reasonable structure, convenient and efficient installation, wide application range and obvious economic benefit.

Description

technical field [0001] The invention relates to a steel structure chimney, in particular to a self-supporting steel structure chimney with an inner cylinder. Background technique [0002] At present, small and medium-sized self-supporting steel chimneys generally adopt factory prefabricated construction site installation. According to the existing transportation conditions and hoisting conditions, the prefabricated length of steel chimneys in the factory is generally 10m to 18m. If the inner cylinder needs to be installed in the outer cylinder, Then the production and installation process is more difficult. Contents of the invention [0003] The purpose of the present invention is to provide a self-supporting steel chimney with inner and outer cylinders, which has a simple and reasonable structure, convenient and efficient installation, wide application range and obvious economic benefits. [0004] The technical solution of the present invention is: a self-supporting stee...
