Novel fluorescent fire door

Abstract

The invention relates to a novel fluorescent fire door. The novel fluorescent fire door comprises a fire door body, a groove is formed in the fire door body, anaccommodating cavity is formed in the side wall of the groove, a fluorescent component A is installed in the accommodating cavity, anda sealing film is arrangedat the position, corresponding to an entrance of the accommodating cavity, of the groove in a pasted mode; a piercing structure is arranged on the side, backing on the accommodating cavity, of the sealing film, the piercing structure is connected with the groove through a compression spring, the piercing structure is further provided with a temperature-sensitive limiting component, and the temperature-sensitive limiting component is used for limiting the position of the piercing structure within a set temperature range; and the groove is furtherinternally provided with a fluorescent component B, the fire door body is provided with a panel at a position corresponding to the groove, the panel has light transmittance, the panel and the fire door body are arranged in a sealed mode toinstall the fluorescent component B in the groove in a sealed mode, the fluorescent component A and the fluorescent component B both have fluidity, and the fluorescent component A and the fluorescent component B have a fluorescent effect after mixing. The fluorescent fire door does not need to depend on a power system, and the fluorescent indication effect can be achieved regardless of whether the power system at the fire site is intact or not.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a novel fluorescent fire door. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. It can prevent the spread of flames and prevent the flow of burning smoke in the event of a fire. In recent years, with the increase of high-rise buildings, the importance of fire doors in buildings has become increasingly prominent, and it is one of the most important fire prevention measures in buildings. However, because most of the existing fire doors lack the indication function, people often use the fire doors and the indication signs together, use the indication signs to form instructions for the users, use the fire doors to provide protection for the safe passage, and then through the fire doors and indications The cooperation of the signs enables the escaped ...

AI Technical Summary

Problems solved by technology

However, the signboards in the prior art often need to rely on the power system at the scene of the fire to work, and in the case of a large fire, the power system is usually severely damaged, which directly leads to the failure of the signboards in the case of a large fire. down is not working

Once the signage fails to work normally, the escaping people or the rescuers rushing to the scene will not be able to quickly and accurately find a safe passage in the case of thick smoke and low indoor visibility, thus delaying the best time to escape or rescue opportunities
