What is the scaffold load standard?

The standard values of construction load of scaffold operation layer are: structural frame 2.7kN/m2 and decoration frame 2.5kN/m2 respectively.

The construction load of scaffold operation layer shall meet the design requirements and shall not be overloaded. Formwork supports, cable wind ropes, conveying pipes for pumping concrete and mortar shall not be fixed on scaffolding, and it is forbidden to hang lifting equipment.

What is scaffolding?

Refers to all kinds of supports erected on the construction site for workers to operate and solve vertical and horizontal transportation. The general term for the construction field refers to the place where external walls, interior decoration or high floors cannot be directly constructed on the construction site. Mainly for construction personnel to work up and down, or external safety net enclosure and high-altitude installation components. To put it bluntly, scaffolding materials are usually bamboo, wood, steel pipes or synthetic materials. Scaffolding is also used as a template in some projects, and it is also widely used in advertising, municipal administration, traffic bridges, mines and so on.

What is the construction load?

Refers to the temporary loads considered for checking the safety of bridge structures or components in the construction stage, such as structural gravity, construction equipment, wind power, one-way thrust of arch bridge, etc.

Usage specification:

safe

1, erection of high-rise scaffolding, all kinds of materials used must meet the quality requirements.

2, high-rise scaffolding foundation must be solid, before erection, after calculation, meet the load requirements, and according to the construction specification, drainage measures.

3, scaffolding technical requirements should comply with the provisions of the relevant specifications.

4. We must attach great importance to various structural measures: bracing, pulling joints, etc. Settings should be made as needed.

5. Horizontal joint sealing: From the first step, every one or two steps, scaffold or scaffold board shall be fully laid, and the scaffold board shall be laid along the long direction, and the joint shall be overlapped on the small bar. Short boards are strictly prohibited. And a long safety bottom fence is laid every four steps between the upright post and the wall.

6. Vertical sealing: from the second step to the fifth step, a protective template railing and skirting board or net with a height of1.000 m shall be set inside the outer row of vertical poles in each step, and the protective poles (nets) shall be fastened with the vertical poles; Above the fifth step, in addition to the protective railings, safety fences or safety nets should be set up; In streets or densely populated areas, from the second step, all safety fences or safety nets should be set outside.

7, scaffolding should be higher than the top of the building or operating surface 1.5m above, and add enclosure.

8. After the scaffold is erected, the steel pipes, fasteners, scaffolding and connection points on it shall not be removed at will. When necessary in construction, it must be approved by the person in charge of the site and effective measures should be taken. After the process is completed, it should be resumed immediately.

9, scaffolding before use, should be organized by the person in charge of the inspection and acceptance, and fill in the acceptance report rear can use. Professional management, inspection and warranty are required in the construction process, settlement observation is carried out regularly, and reinforcement measures are taken in time if any abnormality is found.

10, scaffolding demolition, should first check the connection with the building, as well as the remaining materials on the scaffold, sundry, etc. When cleaning, it shall be carried out from top to bottom in the order of first assembly and then disassembly, and the removed materials shall be uniformly transferred downwards or hoisted to the ground, step by step. Step demolition method is not allowed, and throwing or pushing (pulling) demolition is prohibited.

1 1, scaffolding should set up a warning zone, and hold people alert. In case of gale and bad weather above level 6, the erection and dismantling of scaffolding should be stopped.

12. When the foundation is uneven, please use adjustable feet to achieve balance. The foundation must be able to withstand the pressure of scaffolding and work.

13. Workers must wear safety belts when working at high altitude. Please install a safety net around the work area to prevent heavy objects from falling and injuring people.

14, scaffolding components, accessories in the process of transportation, storage, it is forbidden to seriously fall, impact; When overlapping disassembly, it is forbidden to throw it from a height, and the disassembly should be carried out from top to bottom in turn.

15, pay attention to safety when using, and it is forbidden to play on the shelves to prevent accidents.

16, work is important, but safety and life are more important.
