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...
