How to do a good job in safety control of scaffolding construction
Scaffolding operation belongs to aerial work, which is dangerous, so the whole project construction must rely on scaffolding. Scaffolding is a temporary facility in building engineering, but it is related to the safety management and progress of the whole project. In order to ensure the safety of construction, there are strict requirements on the material specifications, quality and erection requirements of scaffolding, and strengthening the management of scaffolding is the top priority of safety management.
(1) Scaffolding materials shall be standardized and strictly controlled.
In order to ensure the safety of scaffolding, the project department strictly controls the procurement and use of scaffolding materials. Scaffolding materials can be used only after they are uniformly accepted by the security department, the quality department and the user department. There should be connecting devices at both ends of the board, and there should be anti-slip holes on the board surface. Any crack or deformation shall not be used.
(2) Standardize the scaffold technology to ensure that the scaffold is firm and qualified.
Strengthen monitoring to prevent irregular erection of shelves and local instability or collapse. When scaffolding is erected, the length of scaffolding pipe must be selected according to the erection height, and the butt joints must be staggered and not stay in the same span, and the joints are connected into a whole with butt fasteners. It is forbidden to use rotating fasteners for scaffolding docking. All longitudinal and transverse frame beams are provided with supports and splayed supports. At the corner of the shelf, scaffolding should be staggered. Scaffolding should be laid smoothly and each piece should be tied firmly. The uneven places should be padded with boards and nailed firmly, and bricks are not allowed. Scaffolding must be laid vertically and horizontally on the wall, fully spread out in place, leaving no gaps. Effective protective measures must be taken in places that are not completely diffused. Scaffolding must be tied with l8# lead wire in parallel, not less than 4 o'clock, requiring firm binding and smooth connection. Scaffolding should be intact when laid, and should be replaced in time if damage is found. When turning scaffolding on the shelf, two people should do it from the inside out in turn, and a safety net should be set below. Suspended scaffolding should be fixed on a solid part of the structure. Suspended steel pipe suspension scaffolding should have two-way insurance during erection. In addition to the fasteners for columns and rails, the upper and lower ends of the vertical rod should be provided with insurance fasteners, and the length of the vertical rod extending out of the rail at both ends should not be less than 20cm. Dismantling scaffolding should be carried out from top to bottom. It is forbidden to work up and down at the same time or push down the scaffold as a whole. Before the full-house scaffold is erected, the erection scheme shall be approved by the technical director of the construction unit and the chief supervision engineer of the supervision unit. After the scaffold is erected, it shall be signed and listed by the construction and use departments and delivered for use. When the scaffold is delivered for use, there should be written technical and safety disclosure. Always check and maintain during use, and strengthen inspection after heavy wind and rain. Scaffolds that have been stopped for a long time can only be restored to use after inspection and appraisal. The error of the vertical pole, the distance between the large and small cross bars and the height of each step of the scaffold should be controlled within the allowable error range of the specification.
(C) to prevent people's unsafe behavior
In the project design, scaffolding construction can not be completed by experience, so it must be strictly designed and calculated, and the construction management personnel should master its technology and construction requirements to ensure safety. Establish and improve the project safety management organization, send full-time safety production management personnel to carry out safety management, clarify the responsibilities of safety management personnel, improve the safety awareness of management personnel, improve the preparation ability of safety prevention technical measures, and improve the emergency ability of safety management personnel to deal with safety accidents. Formulate targeted and feasible scaffold erection and dismantling schemes, and strictly carry out safety technical disclosure. Safety protection scheme is a document that specifies how to carry out safety protection on the construction site. Therefore, it must be compiled according to the actual situation, construction environment, construction methods and on-site staffing of the construction site, and effective protective measures must be determined in accordance with the provisions of standards and norms, which should be seriously implemented in practical engineering work. Strengthen the training and education of construction personnel, improve safety awareness, enhance self-protection ability, and put an end to illegal operations. When erecting and dismantling scaffolding, the operators should hang up their safety belts, and the operators of poles and poles should cooperate closely. Red-and-white isolation belts or warning signs should be set around the construction, and they should be supervised by special personnel. Irrelevant personnel are strictly prohibited from entering. Scaffolding personnel belong to special operations, and they should receive professional training and obtain valid special operation certificates before they can work independently with certificates. Unlicensed operation is strictly prohibited. Carry out "three-level safety education" for new workers entering the site, and special operators need to undergo special training and pass the examination before taking up their posts. Safety technical disclosure should not stay in oral form, and mutual concern among colleagues is more difficult to replace formal disclosure. Implement safety education and training, improve the safety awareness of construction personnel, and change "ignorance" into "wisdom" and "fearless" into "promising".
