Embodiment Construction

[0031] Such as figure 1 , figure 2 As shown, when the steel pipe column 1 is welded and fixed with the floor support 3 in the prior art, since the stiffening plate 11 is located inside the steel pipe column 1, the stiffening plate 11 cannot be fixed with the floor support 3, resulting in the steel pipe column 1 and the floor support The connection stability of seat 3 is poor.

[0032] In order to facilitate the understanding of the present invention, the following will be described in conjunction with the accompanying drawings and embodiments.

[0033] The present invention provides a steel pipe column internal stiffening plate and baseplate support welding structure, including: steel pipe column 4, stiffening plate 41 and two repair welding steel plates, one end of steel pipe column 4 is connected with baseplate support 5, steel pipe column 4 is connected to the baseplate One end connected to the support 5 is provided with an opposite gap, and the gap is set on the steel p...

Abstract

The invention provides a welding method and welding structure for an internal stiffening plate and a bottom plate support of a steel pipe column. The stiffening plate is a cross-shaped stiffening plate formed by assembling four support plates. The welding method comprises the following steps of forming gaps in connection positions of the steel pipe column and the bottom plate support between adjacent support plates in order to expose the internal stiffening plate of the steel pipe column, and fixing the exposed stiffening plate to the bottom support by welding; and enclosing the gaps with repair welding steel plates. The welding method is simple, and can improve the connection stability between the steel pipe column and the bottom support as well as a pre-buried plate.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a welding method and welding structure of a stiffening plate inside a steel pipe column and a base plate support. Background technique [0002] With the construction of various complex structures in our country, super-large and complex steel structures are more widely used. According to the complex form and stress characteristics of steel structures, it is required that circular pipe columns and box-shaped steel columns should be able to meet the horizontal and vertical loads. Stress characteristics inside the column: Generally, the measures of thickening the wall thickness of the steel pipe column or arranging cross stiffening plates are adopted. The height of the steel pipe column is continuously arranged to enhance the rigidity of the steel pipe column and prevent instability. Comparing the two construction measures, the arrangement of cross stiffeners will save...
