Problems solved by technology

[0002] In recent years, a large number of steel structures have been gradually adopted in domestic buildings. Steel columns are widely used in steel structures. When traditional multi-section steel columns are connected, the three-dimensional adjustment method is to use iron wedges, backing plates, crowbars, etc. The technology is relatively backward, and it is not safe, the work efficiency is low, and the accuracy is not high

Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the utility model is further described:

[0024] The steel column adjuster that the present invention adopts is developed spontaneously, and its structure is as follows figure 1 As shown, the center of the steel column adjuster is a screw rod 1, the upper and lower ends of the screw rod 1 are respectively fitted with a nut 2, the upper and lower parts of the screw rod 1 are threaded in opposite directions, and a nut sleeve 3 is fixed in the middle of the screw rod 1. The outer ends of the nuts 2 at the upper and lower ends are provided with slots suitable for positioning with the steel columns. It is suitable for installing the steel column 5. The cross-section can be in the shape of "O", "I", "T", "T" or "□". Figure 3-Figure 7 shown.

[0025] The three-dimensional adjustment method of the steel column butt joint of the present invention is schematically shown as figure 2 As shown, the specific steps are as follows: ...

Abstract

The invention provides a simple, safe, economic and high-efficiency steel column splicing three-dimensional adjusting method, which adopts a steel column adjuster developed by the inventor to adjust the verticality, height and width of a seam. The method has reasonable process, high positioning precision and advanced technology during the adjusting construction of a steel column, and has remarkable social benefits and economic benefits. The method comprises the following steps of: welding ear plates on a steel column and snapping a center line; lifting the steel column in place, placing the steel column adjuster between the upper ear plate and the lower ear plate according to four directions and adjusting the directions by abutting against the ear plates; fixing an ear plate connecting plate with the upper ear plate and the lower ear plate by using bolts; placing a magnetic plumb bob, adjusting and rotating a middle screw rod till the steel column is perpendicular; determining whether the steel column is perpendicular or not by comparing the distance between the lower end line and the upper end line of the magnetic plumb bob; adjusting the height and the seam while adjusting the verticality; temporally fixing the steel column by using electric welding after the three dimensions of the steel column are corrected; and dismounting a lifting hook and the magnetic plumb bob to finish the mounting by performing final welding and mounting of the steel column.

Description

Technical field: [0001] The invention relates to a three-dimensional adjustment method for butt joints of steel columns, which is mainly used in construction to adjust the verticality and elevation of steel columns, and at the same time adjust the width of horizontal welds to meet design and specification requirements. Background technique: [0002] In recent years, a large number of steel structures have been gradually adopted in domestic buildings. Steel columns are widely used in steel structures. When traditional multi-section steel columns are connected, the three-dimensional adjustment method is to use iron wedges, backing plates, crowbars, etc. The technology is relatively backward, and it is not safe, the work efficiency is low, and the accuracy is not high. Invention content: [0003] The invention provides a simple, safe, economical and efficient three-dimensional adjustment method for butt jointing of steel columns. In this method, a self-developed steel column...
