钢结构的制作施工-中英版
Construction of Steel Structure
钢结构的制作：钢结构制作前要根据现场测量数据，结合图纸尺寸进行放大样。大样放好后应进行校对，现场技术员、施工员应对大样进行验收，经检查验收无误后，方可进行下料。下料时采用自动切割机具切割，自动切割机下料前要进行试切割，调整割嘴的高度、角度，切割机轨道要垫平、垫稳，行进速度要调整好，以保证切割线的平滑顺直。切割前板材表面应清理干净。
Fabrication of steel structure: perform magnified sample before fabrication of steel structure according to measuring data on site combined with dimension on drawing.After checking the magnified sample, technician and constructer on site shall check and accept magnified sample and then carry out blanking through successful checking and acceptance. Adopt automatic cutting machine for cutting during blanking; perform trial cutting before using automatic cutting machine for blanking and adjustheight and angle of cutting nozzle; the cutting machine shall be installed on an even and steady base and its rate shall be well regulated to ensure the cutting line smooth and straight. The surface of material shall be clean before being cutting.
制作时先做好平台，然后将下好的料进行试拼装，检查下料是否正确，拼装后的尺寸是否符合设计要求，检查无误后进行点焊拼装，拼装好后按设计要求要用埋弧焊机进行焊接。施焊前要做好焊接胎位、走道，把焊件放在胎位上进行焊接。焊丝选用HO8锰A型，焊剂选用J431型。焊接时要控制焊缝的厚度，应满足设计及规范的要求，构件焊接后如发生变形的，可根据设计要求采用机械或高温进行调直，以达到设计的尺寸及几何形状的要求。
Make a platform before fabrication and then trial assemble the blanking; check if the blanking is correct and the dimension through trial assemble complies with requirement of design or not, and then carry out spot welding and assembling, after that carry out welding with submerged arc welding machine as per design. Before welding, reserve welding focal position and walkway and put welding parts on focalposition for welding. Take HO8 Mn A-type as welding wire and J431-type as welding flux. Control welding thickness of welding seam during welding, meeting demands of design and regulation. If components deform after welding, straighten them with machine or under high temperature to specific dimension and geometricalshape as per design.
钢结构的安装：钢结构经预制后，用运输车辆运至施工现场，再用小平板车从施工平台运至安装点，再用轻型扒杆吊装就位，进行拼装焊接。安装顺序是先主梁、后次梁、最后安装边梁。安装时先将构件就位，拼装点焊，点焊后再进行尺寸位置检查，无误后进行焊接。焊接要注意温度变化对结构的影响，分点分开施焊，以分散热变形产生的应力。
Installation of steel structure: after being prefabricated, apply transport vehicle to carry steel structure to construction site and then move them to the installation spot from construction platform by flat cars and then use light derrick mast to hoist them to a fixed place for assembling and welding.The installation sequence is from girder to rear secondary girder and finally edge beam. During installation, set components to fixed spots in advance for assembling & weldingand then check size and position after spot welding, finally carry out welding. Pay attention to the influence of temperature on structure and separating points shall be welded individually in order to disperse stress generated from thermal deformation.
钢结构的防腐处理：
Anticorrosion treatment of steel structure:
钢结构制作安装后，应该进行检查验收，验收合格后即应进行除锈防腐：
After installing steel structure, check and accept it; if qualified, carry out anti-rusttreatment after acceptance.
①用砂纸进行人工除锈3遍。
① Manually remove rust by abrasive paper for three times.
②刷底漆：经除锈处理后的构件，报请监理工程师验收后，可进行刷防锈底漆。本工程使用环氧富锌防锈底漆，施工时可用人工涂刷，必须涂布均匀，不产生流坠或漏涂。下一遍油漆要在上一遍干透后进行。本工程对构件的防腐要求三遍底漆，每遍完成后要进行检查，达不到设计要求的应认真整改。
② Paint primer: after anti-rust treatment of wood members, report and require supervision engineer for acceptance and then paint anti-corrosion primer. This project applies Zn-Rich Epoxic Anti-rust Primer, painting manually during construction, which should be uniform without sagging of paint or skip. The second painting should be carried out after last paint has been completely dried.
待防锈底漆施工完毕，并干透后即进行面层油漆施工。根据业主的要求进行施工。
After anti-rust primer has been painted, construct with top finish when anticorrosion primer is completely dry according to requirement of owner.
③注意事项：油漆施工时，要杜绝火种，施工环境要通风，作业人员要戴防护口罩，防止中毒。
③ Notices: put out the kindling when painting, constructionenvironment shall be ventilated and operators shall wear protective mask to prevent from poisoning.
