Manufacturing method of steel structure stair

Compared with the traditional concrete structure stairs, steel structure stairs are relatively simple to make, and can save engineering land more strongly. At present, steel structure stairs are often used as steel workshop, steel structure warehouse and outdoor stairs, in which the Z-shaped steel structure stairs are more common modeling design. Z-shaped steel structure stair is chosen to use continuous Z-shaped thick steel plate welded together, the bending part and the wall are fixed, without other all complex design scheme, compared with the traditional concrete structure stair, steel structure stair can be said to be a perfect match of artistic creativity and simplicity.

Stair material of steel structure is chosen: the material of stair of steel structure can basis user demand, choose international Q-235a class steel or national standard Q-345B class steel, stainless steel plate welding sex is good, economy is practical, processability is good, easy production is processed, suitable large and medium size structure or it is general steel frame structure, its metal material building aesthetics. Steel stair welding method: in the light of the welding processing of steel structure stair, the manufacturer ought to rigorously according to clear processing technology skill and regulation, rigorously reference steel frame structure field design standard regulation, choose carbon dioxide gas protection welding or single pulse direct current argon arc welding machine, and have technical professional technician correction.

Welding node processing: for the stair joint, can be inverted pure processing of the obtuse Angle of the prefabricated components, for the opposite sex friends can try to choose accurate machine processing, so as to ensure that the welding compressive strength and design scheme modeling design comprehensive completion. Surface spraying is treated: regard stair of steel structure as outdoor to a few, construction personnel must undertake surface hot dip galvanizing treatment and undertake coating anticorrosive paint to assure stair of steel structure in the light of prefabricated member of steel frame structure before installation project construction.
