Fabrication of steel column

1 .When start to fabricate steel columns, the first of the actual size according to the drawing release a variety of model of parts processing cutting, shearing, H, wing plate adopt numerical control cutting, web reinforcement plate, connection plate after the shear burr polishing (must rectify all, piece), column top and bottom end stigma adopts semi-auto cutting, grinder grinding level off is smooth, after polishing is similar to milling flat base. On the basis of this assembly in the column above the floor, roof, steel plate, plate connecting the shearing the burr after polishing.

2.Column combination h-beam, wing plate must be connected to it of three boards about 30-50 mm wide, grinding welds then Fang Kehua centerline, three boards combination connection into H.

3. Column combination h-beam, must connect the three boards stick, web and flange centerline deviation must be according to the construction and acceptance of the steel structure engineering.

4. Column after welding is good, you must repair the defects of the rear assembly.

5. Column and of high strength bolt connection between roof board, pay special attention to make correction after the welding process, slightly rough to meet the close degree, and make the whole correction.
