Abstract

The invention provides a fireproof folding door which is applied to the technical field of fire fighting and comprises a door frame, door leaves, a cooling protection device and fireproof cloth, the door frame comprises a side frame, an upper cover plate sealing device, a lower guide rail and a lower guide rail sealing assembly, the upper cover plate sealing device is located above the lower guide rail and is parallel to the lower guide rail, the lower guide rail is connected with the lower guide rail sealing assembly, and the door leaves comprise a first door leaf a and a second door leaf b; the first door leaf b, the second door leaf a, the second door leaf b, the first door leaf b and the second door leaf b are connected with the lower guide rail through pulleys, the upper cover plate sealing device is parallel to the door leaves after the door leaves are closed, the upper cover plate sealing device is located above the door leaves, and the cooling protection system improves fireproof time efficiency and prevents the door leaves from deforming under the condition that the temperature is too high. The problem that the fireproof effect is affected by deformation of the door leaf due to too high temperature is effectively solved, the fireproof cloth, the upper cover plate sealing device and the lower guide rail sealing assembly prevent dense smoke, fire and air from passing through gaps, and the problem that the fireproof effect is affected due to too many gaps is effectively solved.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fireproof folding 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. Fire doors are one of the very common fire equipment. Shafts and other fire-resistant partitions with certain fire resistance, fire doors not only have the function of ordinary doors, but also have the function of preventing the spread of fire and the spread of smoke, which can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel. Today's market There are many structures of the upper fire door. The common fire door will take up a lot of space after opening, and the folding door can just make up for the effect of taking up a lot of space after opening. However, the existing folding door has a large number of gaps in the connec...
