2 meters, and added a brace, brace and the vertical Angle of not more than 30 & deg;
8, in order to prevent the compression of tube bending shelf fasteners from tube head, each link intersecting end were greater than 10 cm.
9, scaffolding, places such as when we have the power cord or electrical equipment need to comply with safety distance, the erection and dismantling adopt measures to stop sending.
When acceptance of 10, scaffolding, appearance inspection should be made for all parts and shall practise a system of acceptance and quotation.
Before 11, scaffolding, need to rack tubes, fasteners, rafts, check, wire rack severe bending tube, fastener severe corrosion, crack, raft and decay, are to be scrapped shall not be used.
12, scaffold can not be directly set on the floor of insensitive and without calculated adding load on the structure of the part, or to fix scaffolding and scaffolding on the structure of the building is not very strong,
Such as the rail, pipe, etc. )

Repair work should check daily use, head of the scaffolding and scaffolding, defects, if any, shall be immediately repaired.
17, conveniently is strictly prohibited to use barrel, wood, brick and other building materials take a temporary planks instead of regular scaffold.
18, prohibit disorderly pull wires on scaffolding.
When need to install the temporary lighting, MuZhu scaffold should add insulator, metal tube scaffold should be another set of wooden cross arm.
19, installing metal scaffolding, banning the use of bending, flattening or cracked pipes, each successive part of the pipe to be intact, in case of dumping or mobile.
20, metal scaffolding poling, need vertically on the plate, to the ground in front of the settlement plate ramming, leveling.
Stud should be set on the column, column base is on the floor by pillar base plate and welding pipe is made.
21, metal tube scaffold joint, the application of special hinge overlap each other, this kind of hinge is suitable for the right Angle, can also be applied to acute and obtuse Angle (
Used to brace, etc. )
Connect the components need to tighten the hinge between the bolt.
22, scaffold board needs to be fixed on the metal scaffolding beam.
23, when the mobile scaffolding, scaffolding all staff have to come down, someone working on the ban mobile scaffold.
Ok, small make up here!
Hope the above content is useful to you, after all, security issues, respectable lick!
