钢结构房屋施工步骤
Construction steps for steel structure houses
(1)下料
(1) Blanking
根据图纸确定下料的尺寸和数量→下非标准件料→下8M房架料→下4M房架料→下支撑钢柱料→下8M房架联接件料→下4M房架联接件料→下钢柱联接件料→下房架檩条和拉条料→将所下材料按用料先后合理摆放并编号下料时对材料要合理使用，做到正确排料，避免不必要的浪费，以减少工程费用。
Determine
the size and quantity of cutting materials according to the drawings →
lay down non-standard parts → lay down 8M room frame materials → lay
down 4M room frame materials → lay down support steel column materials →
lay down 8M room frame connecting parts materials → lay down 4M room
frame connecting parts materials → lay down steel column connecting
parts materials → lay down room frame purlins and braces materials →
arrange and number the materials according to their usage first and then
reasonably, and use them reasonably when cutting materials to ensure
correct layout, avoid unnecessary waste, and reduce engineering costs.
(2)主体结构
(2) Main structure
地面放样→复查尺寸→焊接8M房架正面→刷防锈漆→焊接8M房架反面→刷防锈漆→刷面漆→焊接4M房架正面→刷防锈漆→焊接4M房架反面→刷防锈漆→刷面漆→焊支撑钢柱→刷防锈漆→刷面漆→焊联接件→刷防锈漆→刷面漆→房架檩条和拉条防腐→对所有结构件按吊装顺序编号码放焊接时要注意型材的摆放方向，防腐过程中要将焊渣清除干净。
Ground
setting out → rechecking dimensions → welding the front of 8M room
frame → applying rust proof paint → welding the back of 8M room frame →
applying rust proof paint → applying finish paint → welding the front of
4M room frame → applying rust proof paint → welding the back of 4M room
frame → applying rust proof paint → applying finish paint → welding
support steel columns → applying rust proof paint → applying finish
paint → welding connection parts → applying rust proof paint → applying
finish paint → anti-corrosion of room frame purlins and braces →
numbering and stacking all structural components according to the
lifting sequence, and paying attention to the placement of profiles
during welding During the anti-corrosion process, the welding slag
should be removed thoroughly.
(3)运输
(3) Transportation
确定运输路线→确定装车顺序→装车捆绑固定→为超长超宽构件挂警示标志→将构件按照吊装的反程序进行码放运输时捆绑固定要牢靠防止构件运输途中滑落伤人，装车时注意吊装摆放方式的正确性，支承要合理，避免构件产生塑性变形。
Determine
the transportation route → Determine the loading sequence → Bind and
fix the vehicle → Hang warning signs for ultra long and ultra wide
components → Stack and transport the components according to the reverse
lifting procedure. When transporting, the binding and fixing should be
firm to prevent the components from slipping and injuring people during
transportation. When loading, pay attention to the correctness of the
lifting and placement method, and the support should be reasonable to
avoid plastic deformation of the components.
(4)吊装焊接
(4) Hoisting welding
检查基础尺寸的准确度并弹线→完成电焊机布置并具备使用条件→吊支撑钢柱→找平找正焊接→设置临时爬梯→吊8M房架并固定→焊联接件→吊4M房架并固定→焊联接件→搭跳板→焊房架檩条和拉条→补漆在吊装之前应对构件和钢绳进行一次全面检查，构件有无变形和裂痕，钢绳有无断丝，同时复查预埋件尺寸位置是否准确，以保证工程质量和吊装安全。
Check
the accuracy of the basic dimensions and snap the line → Complete the
arrangement of the welding machine and meet the usage conditions → Hang
the support steel column → Level and align the welding → Set up
temporary ladder → Hang the 8M room frame and fix it → Weld the
connecting parts → Hang the 4M room frame and fix it → Weld the
connecting parts → Build the springboard → Weld the purlins and braces
of the room frame → Touch up the paint. Before lifting, a comprehensive
inspection should be conducted on the components and steel ropes to
check for any deformation or cracks, and whether the steel ropes are
broken, At the same time, recheck the accuracy of the size and position
of the embedded parts to ensure engineering quality and lifting safety.
(5)盖瓦收尾
(5) Cover tile closure
每次作业完成后要把屋顶上的工器具清理干净，盖瓦时搭接方向要一致。
After
each assignment is completed, clean the tools on the roof and ensure
that the overlapping direction is consistent when covering the tiles.
主要项目施工方法
Main project construction methods
(1)结构制作：
(1) Structural fabrication:
a.地面放样。在制作现场按1∶1的比例完成阳雕刻 手套生产设备 果树反光膜 北京纯水设备 保定网站制作 排水槽模具8米房架和4米房架的放样工作。并对所有尺寸进行复查。
a.
Ground layout. Complete the layout work of the 8-meter and 4-meter room
frames in a 1:1 ratio on the production site. And recheck all
dimensions.
b.完成房架正面主框架的制作后，再进行正面防腐。注意在制作时一定要将结构件垫至同一水平后方可焊接，防止结构件产生扭斜。焊接时应将所有构件点焊牢固后才可进行满焊操作，以防因焊缝收缩而导致房架产生焊接变形。
b.
After completing the production of the front main frame of the house
frame, the front anti-corrosion will be carried out. Note that during
production, the structural components must be cushioned to the same
level before welding to prevent twisting and tilting of the structural
components. During welding, all components should be firmly spot welded
before full welding can be carried out to prevent welding deformation of
the building frame caused by weld seam shrinkage.
c.房架反面焊接。正面防腐后将房架翻身进行反面焊接，反面焊接时注意角钢的方向应与正面一致，焊后再进行支脚焊接与防腐。房架翻身时，利用三角架完成，不可强行翻转，以免房架变形。
c.
Welding on the reverse side of the room frame. After anti-corrosion on
the front side, turn over the house frame for reverse welding. When
welding on the reverse side, pay attention to the direction of the angle
steel should be consistent with the front side. After welding, perform
support foot welding and anti-corrosion. When turning over the house
frame, use a tripod to complete it, and do not forcefully flip it to
avoid deformation of the house frame.
d.当完成房架制作后，应对其补漆，并摆放在成品区，以方便下一个房架的制作及装车运输。摆放时摆放方式要正确性，支承要合理，避免构件产生塑性变形。
d.
After completing the production of the frame, it should be repainted
and placed in the finished product area for the convenience
