Scaffolding management standards and management measures

Scaffolding management standards and management measures
First, management standards
1, the construction need to climb over 1.5 m underground work, must build scaffolding, construction units need to choose suitable way of scaffolding, according to the site. Monitor of scaffolding, former captain must by classes or quality inspection for materials;
2, scaffolding, captain must by classes or monitor and the scene of the X-ray inspection acceptance and just can use after the approval of the subject. Staff work on scaffolding, need to hang the safety belt, must appoint the guardianship, X-ray process on site supervision.
3, high operation use of scaffold materials should meet the following security requirements: scaffold made of metal material, the material is not less than 40 mm steel pipe and the bayonet connection, phi configuration recommended: 3000 mm x 300 mm x 60 mm wooden board (recommendation: wood pine). Wooden scaffold materials, materials for 120 mm (width) x 120 mm (thickness) of pine material, with 8 # iron objects silk tie hoop around 3 laps, configuration 3000 mm x 300 mm x 60 mm pine frame plate. Support distributed evenly and spacing is not more than 1.2 m, when the scaffold height more than 2 m to set up the rail.
Use steel tube: do not open the welding, bending, deformation, cracks and other defects, it is recommended to use painted anticorrosive paint for anti-corrosion treatment, unqualified steel pipe must not be allowed to use.
Fasteners: use the manufacturers of qualified products, and hold the product certificate, fastener technical performance meet the requirements of the provisions on the use of fasteners should be checked, can not have defects such as porosity, sand holes, cracks, slippery silk. Fasteners and steel tube joint surface must strictly cosmetic, ensure a good contact with the steel pipe fasten, fastener grip the pole, the fastener activity part of the flexible rotation. 4, high operation using the scaffolding erectness requirements:
Erection of scaffolding, the requirement of steel bar diameter, different diameter steel bar cannot mix; The master node, fixed rod or longitudinal rod, scissors, lateral horizontal, lateral support from the centerline of the fasteners, such as from the master node is not more than 150 mm.
The length of the scaffold base plate shall be not less than 2 across; Thickness should be not less than 5 cm;
Scaffolding of the pole and the distance of the ground shall not be greater than 20 cm;
Scaffold fastener bolt tightening torque should be between 40 m to 65 n * n * m;
Erection of scaffolding, the docking fastener (a word fasteners) opening direction: stud itself, rail up. Docking fastener opening should be toward the inside of the shelf, bolt up, right-angle fastener openings shall not down, in order to ensure safety. Fittings and bracing should be set up in time, shall not delay more than two steps.
Scaffolding each bar end out fasteners on the edge of the plate length should be not less than 100 mm.
Under the scaffolding scaffolding shall not be less than 3 small bar;
Should be paid attention to in the process of the erection, adjust the verticality of scaffolding, maximum allowable deviation 100 mm.
Hang your seat belt requirement: solid suspension, ascend a use.
5, scaffolding demolition order: should according to step by step down the demolition, the first protective bar, scaffolding and lateral horizontal pole, then rip bracing in the upper part of the fastener and jaw.
Second, the management measures
(1) high, "before the job risk assessment team to organize workers shift;
(2) the team monthly organization learning about knowledge of training people working to climb.
(3) regulation, safety, conducting supervision and inspection found not according to standard operation, stop immediately, and for those responsible for the corresponding punishment.
