Steel columns Offset: 1, construction preparation (1) the preparation of steel erection construction organization. Its contents include: calculation of the number of steel members and connections, select hoisting machinery, determine the water program, to determine the lifting method to develop the schedule, determine labor organization, planning member yard, to determine the quality standards and safety measures. (2) the basis of test preparation and steel components. Its contents include: the axis error measure, preparing the foundation bearing surface, the bearing surface and the bearing surface elevation of the level of testing, measuring bolt position and an extended length of the bearing surface and the like. Foundation bearing surface and bolt bearing tolerances compliance. Before lifting should be based on "steel construction and acceptance" (GB50205-2001) requirements, carefully examine the shape and geometry of the steel members, if the deviation before lifting should try to eliminate. (3) if necessary, checking the stability of hoisting steel members, checking formulas please check the relevant information.
