Steel column lifting, welding and quick positioning device

Abstract

The invention discloses a steel column lifting, welding and quick positioning device. The steel column lifting, welding and quick positioning device comprises four positioning steel plates which are mutually spliced into a rectangle, wherein each positioning steel plate comprises a primary steel plate and an auxiliary steel plate which can be partially inserted into the primary steel plate in a sliding mode, the end part, inserted into the primary steel plate, of the auxiliary steel plate is provided with locating pin holes in a vertical direction in a penetrating mode, a plurality of bolt holes which are matched with the locating pin holes are formed in upper and lower side surfaces of the primary steel plate, limiting bolts are arranged in the limiting pin holes and the bolt holes, and welding holes are formed in the primary steel plate and the auxiliary steel plate. The steel column lifting, welding and quick positioning device can regulate effective length of the positioning steelplates by regulating depth, inserted into the primary steel plate, of the auxiliary steel plates, so that precise positioning is realized; and during steel column lifting, the device can be utilized to position and splice, so that safe and stable mounting is realized, and mounting efficiency is improved.

Description

technical field [0001] The invention relates to a fast positioning device for hoisting and welding of steel columns, in particular to a quick positioning device for hoisting and welding of steel columns. Background technique [0002] With the development of construction technology, more and more super high-rise buildings are constructed with steel columns with better bearing capacity. Steel structures are more and more widely used in high-rise civil buildings and other large buildings. Generally, they are composed of steel columns and steel The steel frame composed of beams is used as the main structure. Due to its high building height, the steel columns need to be installed in sections from bottom to top. Due to the limitation of its building space, the hoisting and subsequent adjustment of the steel column beyond a certain height cannot stretch the cable wind rope. How to quickly install the steel column, accurately position it, and ensure the verticality of the steel colu...

AI Technical Summary

Problems solved by technology

For the on-site installation of steel structure cross or H-shaped rigid steel columns, the traditional technology only provides the joint method of connecting plates, but does not provide position adjustment measures for steel column installation. During on-site installation, the lifting operation efficiency is low, and for The installation accuracy of the steel column cannot be guaranteed
