Latticed column welding device and method

Abstract

The invention discloses a welding lattice column device and a welding method, comprising a sleeve frame (100), the sleeve frame (100) including four upright columns (9) and a beam (4) detachably connecting the upright columns (9) ), the beam (4) is divided into several layers from top to bottom, the bottom of the column (9) is fixed on the concrete base (2) by the steel plate (3), the upper part of the sleeve frame (100) and A chain block (6) is provided on the corresponding crossbeam (4) at the bottom, and a shaft (1) is provided at the bottom of the casing (10), and the center of gravity line of the casing (100) is aligned with the center of the shaft (1). Lines overlap. It solves the problem of material waste caused by the direct lengthening of the lattice column in the traditional method and is not conducive to the quality control of the positioning construction of the steel lattice column. The invention adopts the method of supporting by the sleeve frame (100), controlling by the chain hoist (6) and segmentally welding at the wellhead, so that super-long and super-heavy lattice columns can be connected and installed in segments by means of a small tower crane on steep slopes.

Description

technical field [0001] The invention relates to a welding lattice column device and a welding method, in particular to a lattice column welding construction device and a welding method when there is no large hoisting equipment on a steep slope. Background technique [0002] In recent years, with the transformation of old commercial areas in cities, more and more deep foundation pit projects have appeared in prosperous areas with complex surrounding environments. As a result, foundation pit construction is often affected by external factors, such as surrounding high-rise foundations, subways, etc. In order to ensure the stability of surrounding buildings and structures during the construction process, as well as limited by the site, the reverse method is widely used in engineering support forms. Commonly used columns: lattice columns, steel pipe columns, etc. are also increasingly used in reverse construction. In the construction process of the reverse method, there are two ...

AI Technical Summary

Problems solved by technology

This practice will result in waste of materials, and is not conducive to the quality control of steel lattice column positioning construction

If the lattice column is located on a steep slope, it is not advisable to use large hoisting equipment due to the influence of the construction operation surface
