Different types of engineering construction choose different uses of scaffolding and formwork support. Bowl-buckle scaffold is mostly used for bridge support frame, and portal scaffold is also used. Attached below is the safety technology of lifting scaffolding construction that I compiled for you. Welcome to read and browse.
1. Prepare special construction organization design
Attached lifting scaffolding is different from ordinary landing scaffolding and cantilever scaffolding. The technical quality department of the company, after comprehensive consideration, formulates the special construction organization design, including the design and calculation of the attached scaffolding position, construction organization, installation quality requirements, daily inspection and maintenance management, according to the floor changes in the architectural drawings, whether there are decorative lines, circular platforms or balconies, tower crane positions, people and goods elevator positions, building structures and many other factors.
1. Introduce the project overview. The lifting equipment adopts WZ-93 attached lifting scaffold of our company, and the initial erection layer, lifting layer and lifting height of the lifting frame are defined. According to the requirements of the construction period, quality, safety and civilized construction of this project, the safety and civilized standards of this project are put forward.
2. In strict accordance with standards and specifications, specific design indicators are put forward, including the plane position layout, the total height of the frame, the distance between the truss and the building, the diameter and number of supporting lacing bars, the spacing of anti-camber guide wheels and other specific requirements.
3. Put forward specific requirements for the materials and accessories attached to the lifting scaffold, including self-made equipment bearing frame, horizontal truss, vertical frame, hanging beam and anti-falling beam and other attached supporting structures, anti-falling devices, electric hoist, central electric control cabinet, etc. And purchased accessories cables, steel pipes, fasteners, scaffolding, safety nets, bolts, etc.
4. Emphasize the erection requirements and procedures of attached lifting scaffolding, and put forward specific installation quality requirements and quality inspection and acceptance criteria according to the requirements of standards and specifications.
5. The detailed operation procedures for the lifting process of the attached lifting scaffold are compiled.
6. Specific requirements are put forward for the maintenance of attached lifting scaffolding.
7. A detailed dismantling plan is made for dismantling the attached lifting scaffold.
8. Specific technical management and safety management schemes have been formulated.
9. Elaborated the cooperation between the frame, tower crane and people and goods elevator during the operation of attached lifting scaffold.
The preparation of special construction organization design is the basis of ensuring safe production from technical measures.
2. Strengthen the company's safety production management.
In the management of safety production, the company first started with strengthening the awareness of safety production of company leaders, unified understanding and made unremitting efforts around the company. Survival by quality, efficiency by safety and development by reputation? This policy adheres to the following aspects:
1. Strengthen the safety awareness of construction personnel. Safety awareness is people's attitude and judgment in safety activities. Safety awareness is the basis of implementing all other safety measures, and the strength of safety awareness has a direct impact on safety production. The company regularly organizes construction management personnel at all levels to study and implement national laws and regulations on safety, establish a sense of advance, and put accidents first? Prevention first? Always keep it in mind.
2. Improve the safety organization and implement the responsibility system for production safety. The company has established a series of perfect "safety systems", and on this basis, established the company's safety production management network, formulated the safety production responsibility system and safety management target responsibility system for the general manager, deputy general manager, chief engineer, safety department, technical quality department, production management department, project management department and other departments, integrated the safety production responsibility system into all departments and jobs of the enterprise, and regularly assessed and rewarded construction management personnel at all levels according to the requirements of the safety production responsibility system.
3. Adhere to the safety production meeting system. While paying special attention to safety production, the company insists on holding regular safety production meetings, including meetings attended by all departments and safety personnel in the middle of each month and meetings attended by all departments, project departments, safety personnel and construction team leaders in the late of each month. Take the opportunity of the meeting to carefully check the safety production situation in the previous stage, arrange the safety production work in the next stage, investigate the hidden dangers of accidents, implement preventive measures and prevent accidents.
4. Implement the annual safety production funds. At the beginning of each year, the company prepares the annual safety production fund plan, which is approved and issued by the general manager. It is mainly used for safety protection articles and appliances, fire-fighting facilities and equipment, power facilities, safety education and training, safety technical transformation, special activity funds, etc. The funds are earmarked and registered for use. Personal protective equipment, such as safety helmet, safety belt, work clothes, etc. The construction site should be equipped by construction personnel and purchased and distributed by the company, which can not only meet the needs of the construction site, but also ensure product quality and improve safety performance.
5. Do a good job in the education and training of operators. At present, most of the company's construction workers are migrant workers organized by engineering teams. They lack systematic safety education and training, poor safety awareness, and lack basic safety knowledge, self-protection awareness and operational skills before taking up their posts. Before each project starts and the personnel enter the site, the company shall verify the information of the operators, conduct safety education for the personnel entering the site, learn relevant laws and regulations, be familiar with the technological process and operating procedures of attaching lifting scaffolding, and improve the safety awareness of the operators. Attached lifting scaffold construction belongs to a special type of work. The company appoints a special person to organize the personnel without work license to attend the pre-job training in the professional training institutions in the city, and the operators must obtain the work license before taking up their posts.
6. Do a good job in safety inspection and safety data management. In order to ensure that the responsibility system for production safety and construction organization design are implemented in the daily work of each project, eliminate hidden dangers of accidents, improve product quality, ensure construction progress and ensure personal and property safety, the company organizes safety, technology, quality, project management and other relevant personnel to conduct a comprehensive inspection of each project every month, and issues a rectification notice on the spot when problems are found, requiring rectification within a time limit and timely reply. In addition to routine monthly inspections, the company often organizes relevant personnel to organize special inspections before and after holidays, strong winds and heavy rains to ensure that the attached lifting scaffolding is in normal working condition.
At the same time, strengthen safety data management. According to the requirements of the company's safety system, all engineering data such as personnel information, education and training, safety technical disclosure, safety inspection, scaffolding inspection, inspection and acceptance of hoisting process, monitoring and so on are classified and kept. By sorting out and analyzing the data, the weak links of project safety management are found in time, which provides first-hand information for the company's project management.
The company's strong safety production management is a great guarantee for the project safety production.
Three. Strengthen project safety production management
The safety production management of the project department is the focus of the safety production management of the whole company, and it is the important duty of the safety management personnel at all levels of the company to ensure the safety production of each project (engineering team) during the whole construction process. The company's organizers compiled the Azure Company Management Manual, which defined the work priorities of the project managers. Project management personnel stationed in the company's construction site mainly work from the following aspects:
1. Be familiar with the construction organization design scheme before entering the site, know the plane shape and layout in detail, and know the material list and material preparation of Party A and Party B; Familiar with the environment and overall layout of the construction site, and know about temporary facilities, material storage sites, construction electricity, etc. Familiar with the general contractor's construction management organization, understand the situation of relevant personnel, and communicate with each other on safety technology and other issues to facilitate on-site construction.
2. Personnel enter the site to do a good job in employee safety education, handle employee labor protection education cards, fill in employee resumes, verify the information of operating personnel's employment certificates, and collect copies and photos of all personnel's ID cards for the company to file.
3. The materials approach to supervise the site acceptance of the materials approach, strictly control the quality, collect and keep the relevant materials of the materials approach, and do a good job of sampling inspection of steel pipes and fasteners approach.
4. In the erection process of climbing frame, the assembly and erection quality of climbing frame will affect the safety performance and service performance of the frame body during the whole construction period. The project management personnel of the company strictly follow the construction organization design scheme, supervise and guide the operators to assemble and erect the climbing frame according to the operation process. And according to the requirements of the lifting scaffolding quality monitoring table, the following parts are monitored:
(1) The requirements for foundation frame erection conform to the provisions for floor frame erection, and can support the weight of at least five frames.
(2) The bearing frame of the same building must be located in the same plane, consistent with the design drawings, and the following factors should be considered: A. Tower crane with wall B. People and goods elevator C. Whether there is post-pouring belt.
(3) Pay attention to the diagonal installation of truss connection, with vertical plane and horizontal plane.
(4) During the erection of the frame, pay attention to the correct direction of the gantry, set up temporary nodes according to regulations, set up internal protection synchronously with the frame, and control the distance from the building.
5] The upper end of the anti-extraversion guide rail installation guide rail should be higher than the embedded pipe 100mm to maintain verticality.
[6] The overlapping length between the installation guide wheel and the fixed bracket of the camber prevention guide wheel is not less than 100mm, and the guide wheel can rotate flexibly.
Once at the bottom of the protection requirements level off firmly, the inner edge is 200mm away from the building.
Being bottom net green net, white net full pull, every 500mm Rachel a point.
Levies bottom flap should be flat and sealed, each flap should be hinged with thick iron wire at least twice, the flap width is the same, and it is at an oblique angle of 45 with the building. Suitable.

While focusing on monitoring, the project management personnel must insist on daily patrol inspection, fill in the construction management log, safety inspection record and rectification notice, carry out acceptance on the erection process in stages, complete self-inspection and acceptance rating in the erection process, and ensure that the shelves with qualified quality and safe performance are put into use.
5. In the process of lifting the climbing frame, the climbing frame is qualified by the authoritative organization and put into use after the acceptance of the three parties. With the rise of the main project, the climbing frame must be upgraded by one layer from bottom to top. After the main construction is completed, it will be decorated by one layer from top to bottom until the bottom decoration construction is completed. The lifting process of climbing frame is a particularly important key stage in project safety management. According to the requirements of the management manual and combined with his own work experience, the project manager of our company makes careful arrangements for each lifting/lowering, and tracks, supervises and checks the whole process:
(1) According to the Safety Technical Disclosure Table for Lifting Scaffolds, safety technical disclosure should be made to the operators before each lifting, reminding the operators to keep in mind the lifting operation procedures, safety technical measures and precautions at all times, so as to enhance the awareness of safety production.
(2) According to the checklist before lifting the attached lifting scaffold, carefully check item by item, including removal, reinforcement and adjustment, until all lifting conditions are met.
(3) According to the Lifting Notice of Attached Lifting Scaffold, notify the general contractor project department that all the preparations for our climbing scaffold are ready and can be lifted immediately. Please ask the general contractor for acceptance, and notify other construction personnel to leave the construction site and set up a safety restricted area to ensure the safety of lifting.
(4) Arrange each guardian to monitor 3-5 seats according to the table of "Safety Monitoring Posts in Lifting Scaffold", pay close attention to whether there is any abnormality in the monitored parts, and adjust them in time if any abnormality is found, so as to ensure the lifting safety.
