Description

Technical Field

[0001] The utility model relates to the technical field of steel chimneys, in particular to an inner tube segmented suspended load-bearing sleeve chimney. Background Art

[0002] At present, the inner tube of the prefabricated sleeve steel chimney in China realizes "lateral constraint and longitudinal sliding" through the bottom support and anti-sway device. For example, the inner and outer tube type self-supporting steel chimney disclosed in Chinese patent CN101806162B has a lifting load-bearing device with a certain sliding space designed on the upper part of the inner and outer tubes other than the first section for the convenience of transportation and installation. For chimneys with large height and large diameter inner tubes, their dead weight often exceeds 100 tons, and the load is borne by the bottom support. Once the design is not considered enough, there is a risk of acid leakage and corrosion of the supporting structure, which will destroy the strength and stability of the structure and even cause serious safety accidents and economic losses. On the other hand, since the inner tube is a self-supporting structure, considering the load effects such as dead weight, earthquake, wind load and additional bending moment, it is often necessary to select an inner tube with a thicker wall, which increases the material used for the inner tube and the cost of the project.
