STATE STANDARD OF THE USSR UNION

Date of introduction 01.07.1989

This standard applies to scaffolding means used in the process of construction and installation work during the construction, reconstruction, repair of buildings and structures for organizing workplaces at height.

The standard does not apply to structures that combine the functions of scaffolding means with any other functions (formwork, conductor, etc.) or used for lifting or receiving loads (lifts, platforms for receiving loads delivered to heights, etc.), as well as on the chassis of self-propelled scaffolding equipment and the hydraulic drive of scaffolding equipment.

Explanations of terms used in this standard are given in the Appendix.

1. TYPES AND MAIN PARAMETERS

The types and main parameters of scaffolding means must correspond to those given in the table.

(Changed edition).

2. TECHNICAL REQUIREMENTS

2.2.3. Scaffolding means must withstand the load from its own weight and temporary loads from people, materials and wind.

2.2.4. When developing design documentation, the following should be taken into account:

load reliability factor:

1.2 - from people and materials,

1.1 - from its own weight,

1.3 - from the wind;

Intended safety factor:

7 - when calculating steel rope hangers,

9 - when calculating winch ropes intended for lifting people,

4 - when calculating rod hangers,

1.5 - when calculating the fastenings of scaffolding means to building structures,

3.0 - when calculating the specific pressure of supports on the ground,

1.0 - when calculating other elements;

coefficient of operating conditions of structural elements:

0.9 - when calculating racks for stability,

1.5 - when calculating fence railings;

Rollover safety factor:

1.4 - when calculating the stability of free-standing and mobile scaffolding.

2.2.5. The grades of materials of the load-bearing elements of scaffolding means must be specified in the standards or technical specifications for scaffolding means of a specific type.

2.2.7. The mass of assembly elements per worker during manual assembly of scaffolding at a construction site should be no more than:

25 kg - when installing scaffolding at height;

50 kg - when installing scaffolding equipment on the ground or ceiling (with subsequent installation of them into working position by installation cranes, winches, etc.).

2.2.8. The value and direction of the standard load on the railing must be specified in the standards or technical specifications for specific types of scaffolding.

2.2.9. The force on the handles when rotating the manual drives of the scaffolding means should be no more than 160 N (16 kgf).

2.2.10. The excess of the mass of scaffolding from the design should be no more than 3%.

2.2.11. To be lifted by cranes, the scaffolding must have slinging devices.

2.2.12. In box-shaped and tubular structures, measures must be taken to prevent the accumulation of moisture in them.

2.2.15. Steel parts in contact with structural elements made of aluminum alloys must have a coating that prevents the formation of an electrical couple between them.

2.2.16. Scaffolding facilities, the working floor of which is located at a height of 1.3 m or more from the surface of the ground or ceiling, must have railings and side guards.

2.2.17. The height of the fence is indicated in the standards for a specific type of scaffolding. The distance between the horizontal elements of the fence should be no more than 0.45 m or the fence should have a mesh, lattice, etc. filling.

2.2.18. Machine-driven scaffolding means for moving the workplace in height must have: a movement control device located directly at the workplace; lift height limiters; safety devices (catchers) that prevent spontaneous lowering (falling) of the workplace.

2.2.19. Designs of detachable connections must have locking devices that protect them from spontaneous disconnection.

2.2.20. Sharp edges, burrs, cracks, cavities, and delaminations are not allowed on metal parts and elements.

2.3 . Completeness

2.3.1. The delivery set must include: means of scaffolding of a specific type according to the picking list; passport with operating instructions.

2.4. Marking

2.4.1. Each scaffolding device must be marked containing: a trademark (if any) or the name of the manufacturer; product designation (brand); product or batch number; date of manufacture.

2.4.2. The method, location of marking, etc. are indicated in the standards or technical specifications for a specific type of scaffolding.

2.5. Package

2.5.1. The packaging method and transport marking of the packaging are indicated in the standards or technical specifications for a specific type of scaffolding.

3. ACCEPTANCE

3.1. To verify compliance of scaffolding with the requirements of this standard, the manufacturer must conduct acceptance, periodic and type tests.

3.2. The procedure for submitting for testing, the volume of submitted batches, the composition of the tests, the parameters and technical properties being tested, as well as the sequence of their verification must be specified in the standards or technical specifications for a specific type of scaffolding.

3.3. The manufacturer of scaffolding means must draw up a passport for them in the form given in the appendix.

4. CONTROL METHODS

4.1. The quality of materials and products must be certified by certificates from manufacturers.

5. TRANSPORTATION AND STORAGE

5.1. Transportation of scaffolding should be carried out using any type of transport that ensures their safety (from mechanical damage, paint damage, contamination, etc.).

6. OPERATING INSTRUCTIONS

6.2. Scaffolding means must be registered in a logbook in accordance with Appendix, which must be kept at each construction site.

The registration number must be marked in a visible place on the scaffolding member or on a plate attached to it.

6.3. The results of commissioning and periodic inspections of scaffolding equipment must be reflected in the journal in accordance with the appendix.

The timing of periodic inspections is indicated in the standards or technical specifications for a specific type of scaffolding.

7. MANUFACTURER WARRANTY

7.1. The manufacturer must ensure that scaffolds comply with the requirements of this standard, standards or specifications for specific types of scaffolds.

7.2. The warranty period of operation is at least 12 months from the date of start of operation, provided that the consumer complies with the rules of operation, transportation and storage established by this standard.
