Automatic fire door insert bolt structure

Abstract

The invention discloses an automatic fire door insert bolt structure. The automatic fire door insert bolt structure comprises a fire door body and a monitoring control system. A groove is formed in the periphery of the fire door body, and a fire extinguisher is embedded in the groove. The fire door body is internally provided with a plurality of pipelines, a plurality of through holes are formed in the surface of the fire door body, telescopic tubes are embedded in the through holes, switches are connected to one ends of the telescopic tubes, and nozzles are arranged on one sides of the switches. According to the automatic fire door insert bolt structure, a heat-resistant mesh layer and a mineral glass-magnesium fire-retardant layer are arranged in the fire door, a fire door body is a member made of a PVC mold pressing blister material, the four sides of a door panel are sealed into one body after blister is performed, the problem that glue failure possibly occur after long-term side sealing is solved, the spread of fire is prevented, and the safety of personnel and property safety are guaranteed to a greater extent.

Description

technical field [0001] The invention relates to the field of security technology, in particular to an automatic hidden bolt structure for a fire door. Background technique [0002] Many methods and technologies for manufacturing smart fire doors and smart fire door cores have been developed over time. In general, intelligent fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. , usually used for people to pass, and can prevent flames from spreading in case of fire. In recent years, with the increase of high-rise buildings, the importance of fire doors in buildings has become more and more prominent, and it is one of the most important fire prevention measures in buildings. Although there are some intelligent fire doors on the market, which can raise the alarm when a fire occurs, but simply raise the alarm, it cannot extinguish the fire in a timely and effective manner, prevent t...

AI Technical Summary

Problems solved by technology

Although there are some intelligent fire doors on the market, which can raise the alarm when a fire occurs, but simply raise the alarm, it cannot extinguish the fire in a timely and effective manner, prevent the fire from spreading, and easily cause safety accidents and cause economic losses.

[0003] At present, the fire doors in buildings are generally composed of fire door leaves, fire door frames and door closers connected between the fire door leaves and fire door frames. The lighting and ventilation of the ladder are very bad

Now the fire-fighting walking ladder of the building is often used as a public passage, and the flow of people is very frequent, which leads to the frequent opening of the fire door. The property management department of the building even removes the door closer, so that the fire door is always open. The state of the fire door cannot be monitored by the safety inspection of the fire department. Once a fire breaks out, the fire door cannot play the role of isolating the fire, which poses a great threat to public safety.
