Description

Technical Field

[0001] The utility model belongs to the technical field of construction safety in hot work, and particularly relates to a hard partition for construction safety in hot work that can be flexibly assembled. Background Art

[0002] Hot work refers to non-routine operations that may generate flames, sparks, and hot surfaces in a fire prevention area outside of process equipment that directly or indirectly generates open flames. These operations include, but are not limited to, the use of tools or equipment such as electric welding, gas welding (cutting), blowtorches, electric drills, and grinding wheels. When performing hot work, a series of safety measures must be taken to ensure the safety of the operation, including, but not limited to: 1) Using hot work operators who have passed the formal national training and examinations. 2) The welding and cutting operation items should match the qualifications obtained in the special type of work operation certificate. 3) Handling the approval procedures in advance, removing flammable and combustible items, configuring fire fighting equipment, and implementing on-site supervisors and safety measures. 4) Personnel performing operations with fire hazards such as electric welding and gas welding must hold certificates and comply with fire safety operating procedures and implement corresponding fire safety measures. Acts that violate the safety management regulations of hot work may result in serious consequences, including administrative penalties and even criminal liability. Therefore, the management and execution of hot work must strictly comply with relevant laws, regulations, and safety standards.

[0003] In the construction industry, hot work is common at construction sites. Its characteristics are high risk, easy to cause fire and explosion, scattered hot work points at the construction site, and high mobility; as the industry's supervision of safe construction gradually increases, the requirements for hot work at construction sites are becoming more and more strict, and it is essential to set up partitions for hot work. The production of conventional partitions is relatively troublesome, requiring a lot of time and effort, and it is easy to affect the construction progress; secondly, the hot work locations are flexible and changeable, and it is difficult to move the partitions; therefore, it is particularly necessary to develop a simple, effective, and movable partition.
