Problems solved by technology

Since the outer frame steel structure of the building is a honeycomb structure, the size requirements between the axis and the axis are relatively high, which will have a great impact on the honeycomb steel structure to be installed, such as the deviation of the embedded foundation steel column cannot be well resolved problems, it will affect the quality of the entire steel structure project
If the pre-embedded steel column is reworked, it will not only consume a lot of manpower and material resources, but also affect the progress of the project

Embodiment 1

[0031] Example 1. The cross-section of a foundation steel column 1 is a rectangular tube of 600×400mm, and the thickness of the pipe wall is 24mm. The foundation steel column 1 is offset by the design value of 4mm in the X direction (600mm direction), and the design value of the Y direction (400mm direction) is 3mm. . The deviation correction process is as follows: First, an annular groove 3 is milled on the top surface of the basic steel column 1 welded with the sealing plate 2. The groove width of the annular groove 3 is 24mm, which is equal to the wall thickness of the honeycomb grid column 4. The annular groove 3 The center of the center of the base steel column 1 is offset by -4mm in the X direction of the top plane of the base steel column 1, and the Y direction of the base steel column 1 is offset by -3mm, that is to say, the center position of the annular groove 3 is aligned with the design center of the base steel column 1 . Use a semi-automatic cutting machine to m...

Embodiment 2

[0032] Example 2. A basic steel column 1 deviates from the design value of 16mm in the X direction (600mm direction), and there is no deviation in the Y direction (400mm direction). Since the basic steel column 1 has a single-directional deviation, a single-sided steel plate can be used to reinforce the deviation correction structure. The deviation correction process is as follows: Weld a rectangular reinforced steel plate 5 with a thickness of 22 mm, a width of 300 mm, and a length of 700 mm on the side of the negative deviation of the basic steel column 1, and use a cutting machine to process the welding groove 6 on both sides of the reinforced steel plate 5. Welding holes 7 are processed on the reinforcing steel plate 5 . The reinforced steel plate 5 is flattened by a flat machine, and then the reinforced steel plate 5 is sandblasted to Sa2.5 level. When the reinforcing steel plate 5 is welded to the basic steel column 1, the reinforcing steel plate 5 is pressed against th...

Embodiment 3

[0033]Example 3. A foundation steel column 1 deviates from the design value of 30mm in the X direction (600mm direction), and 20mm in the Y direction (400mm direction). Since the foundation steel column 1 has deviations in two directions, double-sided steel plates can be used to reinforce and correct the deviation structure. The deviation correction process is as follows: weld reinforcing steel plates 5 on the two faces of the foundation steel column 1 with negative deviations. One side of the basic steel column 1 with a width of 400 is welded with a rectangular reinforcing steel plate 5 with a thickness of 32 mm, a width of 300 mm, and a length of 950 mm; 950mm rectangular reinforced steel plate 5. The welding groove 6 is processed by a cutting machine on both sides of the reinforcing steel plate 5, and the welding hole 7 is processed on the reinforcing steel plate 5. The reinforced steel plate 5 is flattened by a flat machine, and then the reinforced steel plate 5 is sand...

Abstract

The invention discloses a method and a structure for rectifying deviation of a basic steel column of a honeycomb grid column steel frame building. According to the method, different deviation rectification processes are adopted according to a deviation value of the basic steel column; a weld joint transition deviation rectification process is adopted when the deviation value of the basic steel column is less than 5mm; and a steel plate reinforcement deviation rectification process is adopted when the deviation value of the basic steel column is more than 5mm and less than 35mm. The deviated basic steel column is subjected to deviation rectification by the weld joint transition deviation rectification process and the steel plate reinforcement deviation rectification process, so that the deviated basic steel column is not required to be remade, the problem that the embedded basic steel column deviates is well solved, a relatively small quantity of manpower and material resources are invested, and the engineering progress can be guaranteed on the premise that the project quality is guaranteed.

Description

technical field [0001] The invention relates to a deflection correction method and a structure of a honeycomb grid column steel frame building foundation steel column, belonging to the technical field of steel frame building structures. Background technique [0002] At present, with the continuous development of my country's economy, the architectural style and structure are constantly innovating, and the difficulty and complexity of building construction are also increasing. In particular, some emerging high-rise buildings are introducing new ones in appearance. The outer frame of the tube, the middle is a reinforced concrete core tube, and the outer is a steel frame with a honeycomb grid column structure. The installation of honeycomb grid column steel structure is the first complicated steel structure construction process, and the processing and installation precision of steel components are required to be high. [0003] However, before the hoisting of the steel structure...
