1. Material standards:
The 1. stainless steel is made of high quality brand new stainless steel plate (201 color stainless steel sculpture, 304L matte or mirror hyperbolic surface forging, more stainless steel sculpture, 316L seaside stainless steel sculpture) 1.5-2.5mm thick (according to different environment and different sculpture modeling material and thickness).
2. unused raw materials produced by the original plant and in accordance with the national and industrial standards are used.
Two. Process standard:
The welding of 1. stainless steel is welded by sub arc welding method, welding point interface grinding and polishing, and atomic ash leveling.
2. basic concrete marks are not less than C30, and the foundation and lightning protection grounding system are constructed at the same time.
The fixing bolt and nut based panel by two to 3. pre cast concrete foundation, the panel placed in Euparagonimus, with fixed bolt welded steel.
4. during the winter construction, effective measures must be taken to prevent the frost heave of the foundation pit.
Three. Acceptance criteria:
1. welding shall not affect the strength of crack, slag, overip, burn, craters and needle like pores, and no wrinkle and break the defects.
The 2. stainless steel plate welding spot has no sag, rupture and discoloration. The distance between solder joints is less than 20mm. The welding place is consistent with the original steel plate. The surface is surface, the line is the line, the angle is the corner, and the paint practice is the same as above.
3. the design of anti wind pressure snow load is in accordance with the relevant regulations of the building structure load code GB50009-2001.
4. the welding of the sculptures should be in accordance with the technical requirements of the welding regulations of the construction steel structure GBJ81-91.
The 5. installation is scientific, beautiful and reasonable.
Four. The standard of quality assurance:
1. the warranty period is one year within the project completion date.
2. the damage of the sculpture itself is free of repair during the period of the warranty period, and the maintenance service is only charged for the maintenance of the artificial and material expenses.
