Overhead correction adjuster for box-shaped steel columns in ultrahigh layer steel structure

Abstract

The invention discloses an overhead correction adjuster for box-shaped steel columns in an ultrahigh layer steel structure. Connecting plates are arranged on the four corners of upper and lower steel columns; long holes are formed in the connecting plates on the upper and lower steel columns; high-strength bolts are arranged in the long holes; clamping plates are arranged on the side faces of the connecting plates on the upper and lower steel columns; holes are formed in the clamping plates; the clamping plates are connected with the connecting plates through the high-strength bolts; upper and lower support plates are arranged on the side faces of the upper and lower steel columns respectively; a jack is arranged between the support plates. The overhead correction adjuster for the box-shaped steel columns in the ultrahigh layer steel structure provided by the invention has the beneficial effects that a construction method for correcting the box-shaped steel columns in the ultrahigh layer steel structure is more convenient, safe and practical, the construction efficiency is increased greatly, and the construction cost is reduced.

Description

Technical field: [0001] The invention relates to an adjuster for mid-air correction construction of a box-shaped steel column of a super high-rise steel structure, which is practical and convenient. Background technique: [0002] In the field of steel structure, there are more and more super high-rise steel structure office buildings or urban landmark buildings. Designers often use a large number of steel frames-concrete core tube structures. Box-shaped steel frame columns are connected at high altitudes, and the workload of correction is also increasing The higher the number, the more difficult the high-altitude correction construction of the box-shaped steel frame column is. Since in the steel frame-concrete core tube structure, all the corrections of the box-shaped steel frame column are carried out at high altitude, the traditional wind rope correction method It has been unable to meet the construction needs and safe use requirements, seriously restricting the constructi...

[0002] In the field of steel structure, there are more and more super high-rise steel structure office buildings or urban landmark buildings. Designers often use a large number of steel frames-concrete core tube structures. Box-shaped steel frame columns are connected at high altitudes, and the workload of correction is also increasing The higher the number, the more difficult the high-altitude correction construction of the box-shaped steel frame column is. Since in the steel frame-concrete core tube structure, all the corrections of the box-shaped steel frame column are carried out at high altitude, the traditional wind rope correction method It can no longer meet the construction needs and safe use requirements, seriously restricting the construction progress, greatly increasing the construction cost and increasing the construction safety hazards
