Maintenance:
After the completion of construction, convened by the head of construction technology, safety and the erection team personnel, carry torque wrench, appearance and actual inspection. 

48 mm half inches pipe maintenance:
1 even wall fastening and displacement of reinforced bar. Affecting the construction of the site, measures should be formulated in the technology sector, may shift change effort, the operator shall not, without even the wall displacement of bar.
Observed 2 inch and a half steel scaffolding tube as a whole or partial vertical deviation, especially in observation scaffolding corners, breaking in two side port, whether the deflection, sinking. If found a strange person, shall immediately organize personnel for reinforcement.

3 check carefully whether the federated eye network root bundle loosening, whether the net twine breakage, found loose timely recovery, finding a breaking change in time. 

4 often check shop mat bamboo basketry, timely repair hamstring breaks, fill the hole. And at the same time check the colligation point of bamboo basketry.

5 supervision pile by using personnel material, make it no more than the construction load. Scaffold for masonry, pile of bricks, for example: three layer below the line standard brick, porous brick four layer below the line. 

6 remove accumulated in scaffold materials, brick, concrete block dangerous parts of the clutter.

Welded steel pipe production technology is simple, high production efficiency (1.5 inch pipe shelf life in more than 10 years, longer life after leaching paint or paint), the use of low cost, low price, variety specification more (2.0 4.0 wall thickness can make all kinds of pipe), less equipment investment, but the general strength is lower than the seamless steel scaffolding tube. Welded pipe scaffold is widely a kind of construction site.
