A steel column displacement control method: pouring concrete foundation before setting will chuck pre buried bolt according to the planning range stuck use, to prevent irrigation concrete attack displacement; low column plate reserved hole should be placed the sample that hole after the reserved hole.
Two, steel column footing gap control measures: before hoisting the steel column, steel structure processing and installation should strictly control the foundation elevation, accurate measurement, and according to the measured value on the basis of the appearance of carefully leveling by two; such as grouting, open the irrigation hole in the base plate (as exhaust hole), using steel plate steel at the bottom of the column uneven pad, and pre planned elevation for column bearing plate, and then adopted two grouting.
The three column, the big error control method: straight steel column should be according to the suspension point of accounting hoisting, and it is necessary to adopt measures for lifting more than two points, lifting should be temporarily fixed to prevent lifting deformation; column in place should be promptly added to the temporary support; the error should be corrected in straight, fixed before.
