Description
Technical Field
[0001] This invention relates to the field of fire door technology, specifically to a reinforced fire door structure. Background Technology
[0002] Fire doors are doors that meet the requirements of fire resistance stability, integrity, and thermal insulation for a certain period of time. They are fire-resistant partitions with a certain degree of fire resistance, installed in fire-resistant compartments, evacuation stairwells, vertical shafts, and other similar locations. In building construction, they are specifically used to isolate fire sources and play a crucial role in firefighting. In the event of a fire, people can use fire doors to escape. In addition to the functions of ordinary doors, fire doors also prevent the spread of fire and smoke, stopping the spread of fire for a certain period and ensuring the evacuation of personnel.
[0003] Patent CN208518549U discloses a reinforced steel fireproof door insulation structure, including a frame, an outer door panel, and an inner door panel. Flame-retardant wooden boards are bonded between the frames and are bolted together. The frames are welded to the outer and inner door panels. A perlite board is installed on the inner wall of the outer door panel via anchors, and air inlets are provided on both the outer door panel and the perlite board. A first ceramic seat is adhered to the inner wall of the inner door panel and engages with a heat-conducting plate. Heat-conducting fins are welded at equal intervals on the heat-conducting plate, and one end of the heat-conducting plate extends through a second ceramic seat to the outside of the outer door panel. The heat-conducting plate is welded to a heat dissipation plate, which is also welded with heat dissipation fins at equal intervals. The outer and inner panels of this reinforced steel fireproof door are indirectly in contact through flame-retardant wood boards. Due to the low thermal conductivity of the flame-retardant wood boards, the heat conduction between the outer and inner panels is poor, thus preventing the outer panel from overheating. Simultaneously, multiple heat-conducting and heat-dissipating plates are installed on both the outer and inner panels. During heat convection, the heat-conducting plates absorb heat from the air, and the heat-dissipating plates dissipate it into the air. This reduces heat convection between the outer and inner panels, significantly improving the insulation effect and keeping the outer panel at a low temperature, which is beneficial for rescue and firefighting operations.
[0004] In the above-mentioned technical solution, the outer and inner door panels are in direct contact with the fire environment. When the fire door is opened for people to escape, the high temperature of the door panels may cause injury to people. In addition, the high temperature of the door panels may make it impossible for people to touch them, thus preventing them from opening the fire door and escaping. Therefore, the use of the above-mentioned fire door poses a safety hazard. Therefore, there is an urgent need for a reinforced fire door structure to solve the above-mentioned problems.

[0026] Compared with the prior art, the beneficial effects of the present invention are:
[0027] (1) A reinforced fire door structure, wherein the door panel and the door hinge are connected by a hinge and there is no obstruction on both sides of the door panel. During use, the door panel can be rotated along the door hinge by pushing it regardless of the opening direction. In this way, in emergency situations such as fire, the person escaping does not need to judge the direction of opening the door, thus facilitating the passage of people.
[0028] (2) A reinforced fire door structure, which, through the setting of a visible component on the door panel, allows the sliding column to slide along the sliding groove by pushing the upper block before opening the door panel, thereby exposing the lower side of the glass and enabling observation of the other side from one side of the door panel. This avoids opening the door panel to supply fresh air when the fire is large on one side, which would make the fire more difficult to control and facilitates observation of the fire.
[0029] (3) A reinforced fire door structure, which fills the inside of the insert with beeswax and paraffin wax. When the fire is large, the beeswax and paraffin wax will melt due to the high temperature, causing the pipe head facing the groove to fall into the bottom groove. The clean water inside the bottom groove is sucked into the sponge by the suction pump, which not only helps to isolate heat during a fire, but also plays a role in absorbing smoke.
[0030] (4) A reinforced fire door structure is connected to a water pipe and a fire hydrant. When a fire alarm is triggered, clean water is supplied to the water tank. The clean water is then sprayed on both sides of the door panel through the nozzles, thereby forming a water curtain on both sides of the door panel to prevent the fire from spreading to the door panel. At the same time, the door panel affected by the fire is cooled down to prevent escapers from being burned by the high temperature of the door panel and to improve the safety of passage through the door panel.
[0031] (5) A reinforced fire door structure in which the clean water sprayed by the nozzle flows into the bottom groove through the trough on the bottom plate and can be retained, and is sucked back into the water tank for recycling through the first suction pipe, so as to avoid waste of clean water and save water resources.
[0032] (6) A reinforced fire door structure in which, after a fire occurs, informed personnel can release the handwheel limit by pulling out the latch, and under the gravity of the manual component, the door curtain will roll out from the curtain shaft and then descend together with the manual component to cover the outside of the door panel again, thereby enhancing the fire resistance of the structure.
[0033] (7) A reinforced fire door structure, by setting a manual component, when there are still people who need to escape after the door curtain mechanism has formed protection, the lower beam is manually raised and the two beams are attracted together by magnets to form a lower passage, so that people can continue to escape. The passage formed on the lower side is opposite to the path of smoke dispersion, thereby reducing the leakage of smoke when people escape and improving the safety of escape.

[0074] The working principle of this invention is as follows:
[0075] The door panel 401 and the door hinge 209 are connected by a hinge, and there are no obstructions on either side of the door panel 401. During use, the door panel 401 can be rotated along the door hinge 209 by pushing it, regardless of the opening direction. In emergency situations such as fire, people do not need to judge the direction of the door opening, thus facilitating the passage of people.
[0076] By setting the visible component on the door panel 401, before opening the door panel 401, the sliding column 411 can be slid along the sliding groove 407 by pushing the upper lever 410, thereby exposing the lower side of the glass 406. This allows observation of the situation on the other side from one side of the door panel 401. This avoids opening the door panel 401 to supply fresh air when the fire is large on one side, which would make the fire more difficult to control and facilitates observation of the fire.
[0077] By filling the inside of the insert 415 with beeswax and paraffin wax, when the fire is large, the beeswax and paraffin wax will melt due to the high temperature, causing the pipe head 417 facing the drain 105 to fall into the bottom tank 101. The clean water inside the bottom tank 101 is sucked into the sponge 413 by the suction pump 414, which not only helps to isolate heat during a fire, but also plays a role in absorbing smoke.
[0078] The water pipe 302 is connected to the fire hydrant. When the fire alarm is triggered, clean water is introduced into the water tank 301. The clean water is then sprayed on both sides of the door panel 401 through the nozzle 303, thus forming a water curtain on both sides of the door panel 401. This prevents the fire from spreading to the door panel 401 and cools down the door panel 401 affected by the fire, preventing escapers from being burned by the high temperature of the door panel 401 and improving the safety of passage through the door panel 401.
[0079] The clean water sprayed by the nozzle 303 flows into the bottom tank 101 through the trough 105 on the bottom plate 104 and can be retained. It can also be sucked back into the water tank 301 through the first suction pipe 304 for recycling, thus avoiding waste of clean water and saving water resources.
[0080] After a fire breaks out, informed personnel can release the limit of handwheel 203 by pulling out the latch 205. Under the gravity of the manual component, the door curtain 504 will be routed off the curtain shaft 501 and then lowered to cover the outside of the door panel 401 again together with the manual component, thus enhancing the fire resistance of the structure.
[0081] With the manual component set, when personnel still need to escape after the door curtain mechanism 5 has formed protection, the lower crossbeam 505 can be manually raised and the two crossbeams 505 can be attracted together by magnet 506 to form a lower passage, allowing personnel to continue to escape. Moreover, the passage formed on the lower side is opposite to the path of smoke dispersion, thereby reducing the leakage of smoke when personnel escape and improving the safety of escape.
[0082] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
