Smoke-proof airtight fire door

The invention relates to a smoke-proof fire-proof device, in particular to a smoke-proof airtight fire door for compensating between the gaps of the upper and lower adjacent door members by means of the engaging members for blocking the penetration of thick smoke.

Social prosperity is accompanied by modern buildings. These concentrated modern buildings bring a more comfortable life, but in the event of a fire, the losses will be very serious and the price will be painful. In the rules of building technology, there are rules for setting fire doors. When fires occur, they are used to block the rapid spread of fire sources and increase the time for personnel to escape to reduce the loss of fire.

However, the general fire is basically accompanied by the generation of heavy smoke. Especially the modern building is mostly fireproof building materials, although it can effectively prevent the fire from expanding, but it is also relatively easy to produce a large amount of smoke because the air is not circulating. In the development of most building fires, white smoke that is not hot and floats vertically will be generated at the beginning. When the surrounding oxygen is gradually consumed, it will start to emit black smoke. After a while, the smoke will accumulate. The decline, the density of smoke is getting bigger and bigger, the temperature is getting higher and higher, the toxic gas is getting more and more, the visibility is getting shorter and shorter, the eyes are more and more irritating, the environment of the fire will be rapidly deteriorated, and the danger will begin. rise rapidly.

In a building fire, smoke is a heavy fire in the fire The necessary risk factors have a considerable impact on the evacuation, escape and safety of personnel. The statistical analysis of the number of casualties caused by fires over the years shows that the number of casualties is greatly affected by smoke, which is far more serious than the number of casualties caused by fire and high temperature, and the damage and impact are relatively more serious. In some cases, smoke is often harmed earlier than the temperature in the escape route, so if you can limit the smoke to certain areas, you can avoid many casualties.

The door panel of a general fire door is formed by rolling a metal plate having a certain thickness, and the metal plate is bent a plurality of times during the molding process. From the physical point of view, the radius of curvature of the outer side of the metal plate in the direction of bending is opposite to the inner side. It is larger, so there is a gap between the corner and the corner, especially at the hinge between the door and the door. Therefore, such fire doors can block and limit the fire source to a certain area, but can not provide good smoke resistance at the hinge between the door piece and the door piece.

A number of related literatures on "smoke-proof fire doors" have been proposed, such as the new patents M453780, M487102 and Taiwan invention patent 539047. Moreover, the inventor of the present invention proposed a "fireproof heat insulating door piece and a roll door" and the like in Taiwan Patent Publication No. I371521. In the above publication, in order to solve the shortcomings of the traditional fire door resistance and the flameproof standard, the use of the structurally complicated door member disadvantageously increases the manufacturing difficulty and the manufacturing cost of the door member.

The main object of the present invention is to provide a smoke-proof and airtight fireproof door, which is compensated between the gaps of adjacent door members by means of the engaging members for blocking the penetration of smoke.

Another object of the present invention is to provide a smoke-proof airtight fire door which is compensated between the gaps of adjacent door members by means of engaging members for blocking the outward diffusion of the flame.

In order to achieve the above and other objects, the present invention provides a smoke-proof airtight fire door, which is composed of a plurality of door unit serially connected, each of the door unit including a door member and an engaging member; wherein the door The sheet member has a first surface and a second surface, the upper end of which extends laterally to form a concave trapezoidal mortise on the same side of the second surface, and the end forms an opening along the upper edge of the trapezoidal rim to oppose the trapezoidal mortise Upper hinge. The lower end of the door member extends laterally to form an oblique bottom portion on the same side of the second surface, and the end defines an lower hinge portion at the upper edge of the oblique bottom portion opposite to the oblique bottom portion. The lower end of the engaging member includes a trapezoidal cymbal, correspondingly embedded in the trapezoidal mortise, and a compensating portion is laterally extended along the upper end of the mortise. The compensating portion has a vertical surface flush with the first surface of the slat member, and a The inclined surface corresponds to the oblique bottom surface of the oblique bottom.

Furthermore, a first bending portion is included between the upper end of the door member and the trapezoidal eye, and a second bending portion is included between the trapezoidal eye and the upper hinge; the fitting is in the compensation Between the vertical surface of the portion and the trapezoidal head, including a first circular recess corresponding to the first bent portion, and between the inclined surface of the compensation portion and the trapezoidal head, including a second bend corresponding to the second bend The second circular recess of the fold portion enables the engagement member and the door member to be in close contact with each other when engaged.

Preferably, the inner diameter of the upper hinge corresponds to the outer diameter of the lower hinge, both on the same center line.

In another embodiment of the smoke-proof airtight fire door of the present invention The door piece unit is formed by the first door piece member and the second door piece member interlacing; wherein the upper end of the first door piece member extends laterally, forming a concave trapezoidal mortise on the same side, and the end along the The upper edge of the blink forms an upper hinge opposite to the mortise; the lower end of the first flap member extends laterally, forming a concave arc-shaped mortise and a slanted oblique bottom on the same side, and the end Forming a lower hinge portion opposite to the arc-shaped mortise along an upper edge of the oblique bottom portion; the upper end of the second door member extends laterally to form an upper engaging portion on the same side of the first door member, The lower portion of the upper engaging portion has a trapezoidal head correspondingly embedded in the trapezoidal mortise. The upper portion of the upper engaging portion includes a lateral compensating portion having an upper inclined surface; the lower end of the second flap member Translating, forming a lower engaging portion on the same side of the first door member, the upper portion of the lower engaging portion having a circular arc-shaped boring head correspondingly embedded in the circular arc-shaped mortise, the lower portion of the lower engaging portion Including a slanted bottom, and the slanted bottom has a slanted bottom surface corresponding to The inclined surface.

Accordingly, the compensation between the door member or the first door member and the second door member by the fitting member can improve the flatness and density between the bending angle and the bending angle caused by the bending of the metal plate. The degree of jointing makes the door curtains connected in series by the door piece unit completely flat and close, which can block the penetration of smoke.
