1. The load of the scaffold should not exceed 260kg / m2, and it can only be used after being qualified and listed. It should be checked and maintained frequently during use. Loads exceeding 260kg / m2, or special forms of scaffolding should be designed.
2. Steel pipe columns shall be provided with metal bases, and planks or sweeping rods shall be provided for the soft geological foundation.
3. The scaffolding poles should be vertical, the vertical deflection should not exceed 1/200 of the height, and the distance between the poles should not exceed 2 meters.
4. Scaffolding ends, corners and every 6-7 columns should be provided with sharp knife stays and supporting rods. When the height is more than 7 meters, supporting rods cannot be installed, every 4 meters vertically and every 7 meters horizontal The objects are firmly connected.
5, the scaffold outside, ramp, platform set 1.05 meters protective fence. When laying bamboo rafts or wooden boards, both ends must be tied tightly. It is strictly prohibited to put them into use without binding.
6. Scaffold crossbars should be elevated and reinforced at the passages and escalators so as not to obstruct the passages.
7. The scaffolding of the pick-up scaffolding is generally 1.2 meters in step, and diagonal braces should be added. The angle between the diagonal brace and the vertical plane is not greater than 30 °.
8. In order to prevent the bending and bending of the shelf pipe from sliding down from the pipe head, the ends of the bars that intersect and protrude are greater than 10 cm.
9. If there are power lines or electrical equipment in the place of scaffolding, the safety distance must be complied with, and power transmission and stopping measures should be taken during installation and removal.
10. When the scaffold is accepted, all parts should be visually inspected, and the acceptance and listing use system should be implemented.
11. Before setting up the scaffold, you must inspect the shelf pipes, fasteners, bamboo rows, and wire. The shelf pipes are severely bent, the fasteners are severely corroded and cracked, and the bamboo rows must be scrapped and not used.
12. It is forbidden to lay the scaffold directly on the wooden slabs of the floor and the structural parts that have not been calculated for the added load, or to fix the scaffolding and scaffolding on structures that are not very strong (such as railings, pipes, etc.)
13. The scaffolding and scaffolding should be firmly connected to each other. Both ends of the scaffolding board should be placed on the crossbar and fixed firmly. Scaffolding must not have joints between spans.
14. Scaffolding and ramp boards should be spread on the crossbars of the rack. On both sides of the ramp, at the bend of the ramp and outside the scaffolding working surface, a 1m high railing shall be provided, and a guard plate 18cm high shall be installed at the lower part.
15. Scaffolding should be equipped with a solid ladder to allow staff to get on and off and carry materials. When lifting a heavy object with a lifting device, it is not allowed to connect the lifting device with the structure of the scaffold.
16. The scaffolding work leader shall inspect the scaffolding and pass a written certificate before using it. The person in charge of the maintenance work shall check the condition of the scaffolding and scaffolding boards used every day. If there are any defects, they must be repaired immediately.
17. It is strictly forbidden to use wooden barrels, wooden boxes, bricks and other building materials to replace temporary scaffolding.
18. It is forbidden to randomly pull the wires on the scaffolding. When temporary lighting circuits must be installed, wooden bamboo scaffolding should be provided with insulators, and metal pipe scaffolding should be provided with wooden crossbars.
19. Install metal scaffolding. It is forbidden to use bent, flattened or cracked pipes. The successive parts of each pipe must be intact to prevent it from falling or moving.
20. The pole of the metal scaffolding must be placed on the support plate vertically, and the ground should be compacted and leveled before the support plate is placed. The pole should be sleeved with a column base, which is made of the base plate of the pillar and a pipe welded to the base plate.
21. The joints of metal scaffolding should be overlapped by special hinges. This kind of hinge is suitable for right angles, but also for acute angles and obtuse angles (for diagonal braces, etc.) The hinge bolts connecting the various components must be tightened.
22. The scaffolding board must be fixed on the beam of the metal pipe scaffolding.
23. When moving the scaffold, all staff on the scaffold must come down. The scaffold with someone working on it is forbidden to move.
