Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building steel structures, in particular to a box-type steel column reinforcement structure and on this basis, also to a steel frame structure. Background Art
[0002] During the welding process of steel frame structures, the welds of the steel columns of the steel frame structures often crack due to the current, welding material selection, welding method, welding material and parent material element content during the welding process. In order to solve the cracks in the welds of the steel columns, the existing technology generally adopts the method of planing the welds and re-welding the steel columns. However, this method, on the one hand, will generate a high temperature of more than 1000℃ during re-welding, which will melt the surrounding welds and steel materials, posing a great safety hazard; on the other hand, the welds of the steel columns are long, and the planing work of the welds needs to be carried out in sections, which prolongs the construction period. Moreover, after the welds are planed, the steel frame structure needs to be temporarily reinforced, further increasing the time and material input costs.
[0003] In addition, according to the requirements of Article 8.3.4 of the Code for Seismic Design of Buildings (GB 50011-2010) (2016 Edition), the thickness of the inner partition shall not be less than the thickness of the beam flange, and all four sides of the inner partition shall be connected to the box-type column wall plate. However, in the actual on-site operation, the thickness of the inner partition is often less than the thickness of the beam flange, and the welding effect between the inner partition and the inner wall of the box-type steel column is not good, resulting in the four sides of the inner partition not being fully connected to the inner wall of the box-type steel column, making the structural strength of the box-type steel column fail to meet the requirements of the national standard. After the box-type steel column is welded, the inner partition is completely wrapped and covered by the box-type steel column, making it impossible to reinforce the inner partition in situ to improve the bearing capacity of the box-type steel column.

For example, the four wall columns of the outer wall of the box-type steel column 1 are respectively connected with a Y-shaped box-type steel frame beam 6, a Y-shaped H-shaped steel frame beam 7 and two X-shaped box-type steel frame beams 8. The position where the outer wall of the box-type steel column 1 is connected to the steel frame beam forms a beam-column node. Moreover, the four wall columns of the box-type steel column 1 are respectively subjected to the tensile force of the steel frame beams corresponding to the four wall columns. In order to improve the bearing capacity of the box-type steel column 1, when manufacturing the box-type steel column 1, an inner partition with a thickness not less than the thickness of the flange of the steel frame beam is usually welded at the position corresponding to the inner wall of the box-type steel column 1 and the beam-column node. However, in the actual production and manufacturing process, it is usually the case that the thickness of the inner partition is less than the thickness of the actual flange of the steel frame beam, and the welding quality of the inner partition and the inner wall of the box-type steel column 1 is poor, so that the actual bearing capacity of the box-type steel column 1 cannot meet the standard.

Preferably, the cross-sectional area of the square ring between the square contour and the outer wall of the box-shaped steel column 1 is greater than or equal to the cross-sectional area of the internal cavity of the box-shaped steel column 1. In other words, the cross-sectional area of the square ring is greater than or equal to the cross-sectional area of the inner partition installed on the box-shaped steel column 1, so that the first outer ring plate assembly 3 can at least provide the bearing capacity provided by the inner partition, for example, Figure 2 When the size of the box-shaped steel column 1 is 500 mm×500 mm×20 mm, the size of the square profile is preferably 800 mm×800 mm. In addition, the thickness of the first outer ring plate 301 is preferably 20 mm.

Preferably, the cross-sectional area of the square ring between the square contour and the outer wall of the box-shaped steel column 1 is greater than or equal to the cross-sectional area of the inner cavity of the box-shaped steel column 1. In other words, the cross-sectional area of the square ring is greater than or equal to the cross-sectional area of the inner partition installed on the box-shaped steel column 1, so that the second outer ring plate assembly 4 can at least provide the bearing capacity provided by the inner partition, for example, Figure 2 When the size of the box-shaped steel column 1 is 500 mm×500 mm×20 mm, the size of the square outline is preferably 800 mm×800 mm.
