Your attention shall be drawn to the fact that backfill around the foundations shall be tamped Table2-1 allowable deviation of bearing surface and anchor boltItem Allowable deviation (mm)elevation 3Bearing surfaceLevelness l/1000Bolt center deviation 5Anchor boltBolt exposed length 20, 0When columns are lifted and dropped down on concrete, putting shim group on both sides of every anchor bolt to align and level columns. 钢结构在形成空间钢度单元后，应及时对柱底板和基础顶面的空隙采用细石混凝土二次浇灌。 4After steel structure is formed into space rigid unit, fine aggregate concrete2.3 material and steel components acceptance2.3.1 Inspection of materials1) There must be warranty and certificate with inspection for materials. If there are changes in material, material list of replacement is required.2) The surface and section of steel must be free of cracks, fold, bubbles, slag and delamination, and the depth of surface defects shall be less than half of steel plates under-thickness tolerance3) High strength bolt, nut and gasket demand certificates which comply with specification of design and national standard.2.3.2 Steel components acceptanceUpon the delivery of H steel to the job site , the manufacturer shall provide the following files :1）The certificate of quality for products2）Construction drawings and the files of design change3）Agreement about technical problems handling4）Quality certificate or test report of steel, connection material and coating material.5）Test report of slip coefficent of faying surface of high strength bolt and coating material filesTable 2-2 allowable size deviation of steel components Item Allowable deviationcolumn bending rise 5 mmconnection 3 mmcolumn distortionThe other connection 8 mmconnection 3 mmThe dimension of column cross-section The other connection 4 mmconnection 1.5 mmFlange plates verticality to web plate The other connection 5 mmweb plate center offset 2 mm 52.4 Storage of steel components1） In principal, the steel components shall be padded with wood and stored according to its type and installation sequence to avoid the secondary transportation. The padded wood shall provide enough bearing surface to prevent supporting point settleing.2）Steel components of the same model should be stacked in such a way that the support of layers is on the same vertical line to prevent the possible damages and deformation.3）High strength bolt connections shall be stored according to lot number and the bolts of the same lot number shall be used. At stages of storage, transportation and erections, they shall be handled carefully and should not be used in the mixed way, so that the surfaces are protected from corrosion, damages and dampness.2.5 Steel components fabricationThe procedure of fabrication of steel components材 料检 验构件制作 检查焊接检 查返修焊接 组装检 查 组装矫正弯曲 和边缘加工号 料、切割放样检 查放样除锈构件验 收构件堆 放防 腐、编号Figure2-2 The procedure of fabrication of steel components2.5.1 Assemblage platformPut the wood on the tamped soil at 1m intervals, and then put steel I-beam after leveling, then floor the platform with steel plate. The allowable deviation of platforms flatness is 5mm, and there shall not be welding beading and dirt left in its surface.2.5.2 Setting-out, marking and cutting1) As regards to setting-out and marking, there shall be shrinkage allowance for welding and cutting according to techniques requirement
