Quality Check Standards of Scaffolding Planks in the Real Construction

Time:2017/07/16

1. The appearance of hot dip galvanized steel scaffolding planks size length is not restricted, generally width is 240 mm, 250 mm, height 65 mm, 50 mm respectively. Steel scaffolding planks dimension allows error: should not be more than + 3 mm in length, width

2. Steel scaffolding planks frilled edge corners should be maintain 90 °, the deviation is unfavorable exceed.


3. Steel scaffolding planks, board face should level off, the plate deflection should not be more than 5.0 mm. The floor of the stability of the best triangular shaped grooves, compared to the third generation of hot galvanizing trapezoidal groove design more scientific, more solid work under pressure.


4. Steel scaffolding planks corners tilted bias: put on standard steel board surface, in any of the four corners of plate tilted Angle, should not be more than 5.0 mm.


5. Steel scaffolding planks ruffled the arc radius should be less than 4.0 mm.
 
6. Steel ramp edge burr file must be smooth, etc.
 
7. Every 500 ~ 700 mm steel plank opposite inserts a card slot stiffening rib plate. Steel scaffolding planks stiffener spacing error should not exceed, end plate size error is not more than.

8. Welding requirements: use fullwelding end plate, stiffener adopt welding, the weld should not be less than 2.0 mm, the weld width should not be less than 2.0 mm. Stiffening rib intercostal welding each weld length should be not less than 10 mm, weld should not be less than 10.Stiffening rib plate using spot welding, solder joint length 15 mm or greater, solder joints, six or more weld height of 2 mm or more. End plate welding head should be seven or more solder joints, especially on both sides of the strengthen welding, weld technology requirements of 3 mm in height.
