The upper end of the door panel member extends laterally to form a concave trapezoidal mortise, and the distal end of the door panel member is formed with an upper hinge portion along the upper end of the mortise in which the upper hinge portion has an opening opposite to the mortise. The lower end of the door panel member laterally extends to form an oblique bottom portion, and the distal end of the door leaf member is formed with a lower hinge portion along the upper edge of the oblique bottom portion in which the lower hinge portion has an opening opposite to the oblique bottom portion. The lower end of the inserting member includes a trapezoidal tenon correspondingly embedded in the trapezoidal mortise. The upper end of the inserting member extends laterally along the upper part of the tenon to form a compensation portion. The compensation portion includes a vertical surface aligned with the surface of the door panel member, and an inclined surface corresponding to an oblique surface of the oblique bottom portion. Accordingly, the inserting member compensates for the gap between the upper and lower adjacent door panel members so as to completely seal up the gap and thus block infiltration of heavy smoke.

Description

Smoke blocking gas tight fire door

The invention relates to a smoke blocking fire prevention device, in particular to a smoke blocking gas-tight fire door for compensating the gap between upper and lower adjacent door sheet members by inserts to block the penetration of dense smoke.

Social prosperity is accompanied by modern buildings. Although these centralized modern buildings bring a more comfortable life, once a fire occurs, the damage will be very serious and costly. Of course, the technical code of the building regulates the installation of fire doors, which are used to block the rapid spread of fire sources in the event of a fire, increase the escape time of personnel, and reduce the loss of fire.

However, fires are generally accompanied by heavy smoke, especially modern buildings are mostly fire-resistant building materials. Although it can effectively prevent the fire from expanding, it is relatively easy to generate a large amount of thick smoke because air is not flowing. In the development process of most building fires, white smoke that is not high in temperature and rises vertically at the beginning will start to emit black smoke when the surrounding oxygen is gradually consumed, and the smoke layer will accumulate after a period of time. With the decline, the density of smoke is getting higher and higher, the temperature is getting higher and higher, the poisonous gas is getting more and more, the visibility is getting shorter and shorter, the eyes are getting more and more irritating, the fire environment will deteriorate rapidly, and the danger will begin to rise rapidly.

In a building fire, smoke is a very important part of the fire burning process. Important risk factors have a serious impact on evacuation, escape and safety of personnel. The statistical analysis of the number of casualties caused by fires over the years shows that the degree of harm from heavy smoke to the number of casualties is far greater than the number of casualties directly caused by the high temperature of fires, and the harm and impact are relatively more serious. In some cases, smoke is often injured earlier than the temperature on the escape route, so if you can limit the smoke to certain areas, you can avoid many casualties.

The doors of general fire doors are formed by rolling a metal plate with a certain thickness. The metal plate is repeatedly bent during the forming process. From a physical point of view, the radius of curvature of the metal plate on the outer side relative to the inner side. Larger, so there will be gaps between the corners and corners, especially at the hinges between the door panels. Therefore, although this type of fire door can block and restrict the fire source in a certain area, it cannot provide good smoke blocking performance at the hinge between the door and the door.

It is known that many relevant literatures on "smoke-resistant fire doors" have been proposed, such as Taiwan bend new patents M453780, M487102 and Taiwan invention patent 539047. Also, for example, the inventor of this case proposed a "fireproof and heat-insulating door sheet and rolling door" in Taiwan Invention Patent Publication No. I371521. The above-mentioned publications, in order to solve the shortcomings of the traditional fire door in terms of smoke resistance and insufficient fire resistance standards, use a door member with a complicated structure, which disadvantageously increases the manufacturing difficulty and manufacturing cost of the door member.
