Column base structure of large-span steel structure trestle

Abstract

The invention discloses a column base structure of a large-span steel structure trestle. The column base structure comprises a steel structure trestle and stand columns, wherein the stand columns arearranged below the steel structure trestle, and are connected with the steel structure trestle; height adjusting devices are arranged at the bottoms of the stand columns; the height adjusting devicesare fixedly connected with foundation embedded parts; the height adjusting devices comprise locating devices, stand column connection plates and bolt adjusting assemblies; the locating devices are fixedly arranged on the foundation embedded parts; the stand column connection plates are arranged above the locating devices; the bolt adjusting assemblies are arranged between the locating devices andthe stand column connection plates; the bolt adjusting assemblies are connected with the locating devices; the bolt adjusting assemblies are also connected with the stand column connection plates. According to the column base structure of the large-span steel structure trestle, the height adjusting devices capable of adjusting the heights of the stand columns are arranged at the bottoms of the stand columns in order to reduce the horizontal thrusting force generated on a central column of a stacker by the steel structure trestle, so that the central column is protected from cracking, and the service life of the central column of the stacker is prolonged.

Description

technical field [0001] The invention relates to a column foot structure, in particular to a column foot structure of a long-span steel structure trestle bridge. Background technique [0002] In industries such as electric power, papermaking, and steel, there are often stacking sites, where bulk materials are automatically stacked by combining stackers and steel structure trestles. In order to ensure the usable area of ​​the stacking site, the span design of the general steel structure trestle is relatively large, but the span of the steel structure trestle is too large, which will lead to more and more complicated stress between the steel structure trestle and the stacker. As the span of the steel structure trestle becomes larger, the stress (horizontal thrust, vertical pressure) on the central column of the stacker also gradually increases. Generally speaking, there is no problem with the vertical pressure on the central column of the stacker, but the impact of the horizon...

Problems solved by technology

Generally speaking, there is no problem with the vertical pressure on the central column of the stacker, but the impact of the horizontal thrust on the central column of the stocker is particularly large, and the long-term impact is likely to cause the central column to break
