1、 Safety requirements of chimney installation platform
1. All site construction personnel must wear safety helmet, and high-altitude operators shall wear safety belt and climbing shoes.
2. Lifting workers and welders shall operate with certificates, and operation without certificates is strictly prohibited.
3. The use of scaffold should be signed by the safety manager, and the super high scaffold should be provided with anti overturning technical measures.
4. If the edge of the binding is sharp, protective measures should be taken (such as wood cushion).
5. The use of binding lifting point shall be tied according to the position in the schematic diagram, and the position of ceiling shall not be changed at will.
6. All operators shall operate in strict accordance with the operating procedures.
7. The command of the commander should be clear and understandable, and the non commander should not conduct command.
8. Because the cross operation in the construction can not be avoided sometimes, it should be coordinated with each other reasonably to ensure the safety; if it has an impact on the safety, the cross operation should be stopped immediately.
9. The perpendicularity and error rate of the column shall be controlled within: single column ≤ 10 mm; multi section column: bottom column ≤ 10 mm; upper section column ≤ 35 mm.
10. The installation of the beam should be straight, and the error rate should be controlled within:?. ≤ H / 250; but not less than 15mm, f ≤ L / 1000, but not more than 10mm.
11. In case of double crane, the action shall be consistent, coordination and command shall be appropriate; for different types of cranes, special attention shall be paid to whether the lifting speed and rotation speed of the two cranes are consistent.
12. Trial hoisting shall be carried out for large components before hoisting. After 15cm away from the ground, the conditions of lifting points, steel wire ropes and cranes shall be observed to ensure safe installation.
13. Before use, the hanging basket should be lifted with iron and then used again.
14. The truss beam shall be prevented from overturning during lightering.
15. Each process should be finished, materials used up and site cleared.
16. The selection of all lifting appliances and tools is based on simple structure, convenient use, safety and reliability.
17. Every construction operator should have the concept of cost awareness and make every effort to reduce the cost.
II. Quality requirements for chimney construction
1. The product quality and coating thickness of aviation sign paint shall meet the design requirements.
2. No missing brush is allowed, and the junction of red and white should be straight and clear. The roller and brush of red and white paint shall be separated and mixed.
3. The aviation color code shall be painted in different times, and then the next time shall be applied after the previous layer is completely dry. It is not allowed to brush the thickness required by the design at one time.
4. The construction of aviation sign paint shall meet the requirements of temperature and climate of the paint, and the relative humidity shall be less than 85%. It shall not be applied under the conditions of rain, fog and large dust.
III. construction safety precautions
1. The personnel participating in high-altitude operation must be in good health, pass the physical examination, and have a strong sense of quality, safety and civilized construction. All operations are under command.
2. The team leaders participating in the construction have strong construction organization ability and can read drawings.
3. Operators, electricians, welders and other special types of work must hold valid certificates.
4. The construction personnel shall strictly perform their duties and carry out the construction according to the operation regulations.
5. Safety helmet and slippers must be worn when entering the site, and the climbing operator must fasten the safety belt correctly.
6. It is strictly forbidden to work after drinking or with diseases.
7. Throwing objects from high altitude is strictly prohibited.
8. High altitude operation shall be stopped in windy and foggy weather.
9. In order to prevent the basket from being pulled up by the steel wire rope due to the self weight of the steel wire rope when the hanging basket rises to a certain height, the weight block shall be placed in the basket. And it is placed firmly and reliably.
10. The hanging basket must be hoisted for a trial time before each passenger riding, and passengers can be carried only after the trial hoisting operation is good. Before using the basket, the safety wire rope of 3T chain hoist must be checked for good performance, safety and reliability.
11. No noise, smoking and hot work are allowed during construction. Put an end to fire at the construction site.
12. The operator wants to concentrate and is not allowed to leave the post without authorization. During operation, the signal should be clear, no wrong operation is allowed, and intercom is used for up and down communication.
13. It is forbidden for non operators to enter the operation room.
14. Before construction, safety operation ticket must be issued and safety and technical disclosure shall be conducted to all operators.
15. The qualified and responsible welders shall be selected for welding during the basket processing, and the welding at the processed hanging basket, lifting ring and steering wheel shall be inspected and signed.
16. For the processing of hanging basket used for chimney platform installation, the qualified and responsible welder shall be selected for welding; the welding of the basket, lifting ring and steering wheel after processing shall be accepted.
