Description

Labeled door

The utility model relates to a kind of door, and particularly a kind of high temperature, structural strength that can effectively intercept the scene of a fire reaches safe labeled door well.

Fire has caused greatest infringement for people's lives and properties, and in order to reduce these infringements, when fire took place, at first, most important work was to control the intensity of a fire rapidly or the escape that loses no time, just can guarantee the safety of life and property; In addition, when fire takes place, the main cause that personnel die is to be choked to death by dense smoke, the door Yin Gaowen of escape destroys by fire and can't use, cause injures and deaths, be minimizing scene of a fire personnel's the casualty rate and the loss of property, more and more Duo fireproof building material is developed, with the labeled door is example, labeled door must have firm overall structure, better heat radiating effect and can reach door-plate when 1000 ℃ high-temperature situation, after continuing for an hour, the back of the body temperature of this door-plate is lower than the safety requirements below 260 ℃, therefore, when the building breaking out of fire, be provided with the labeled door that conforms with this safety standard, could intercept the fierce intensity of a fire and continue to prolong burning, and guarantee the safety of personnel's life and property to other buildings and can keep the intact of labeled door.

As shown in Figure 1, labeled door 1 in the past includes an internal hilar plate 11, an external door panel 12, filling is in the heat-barrier material 13 of 11,12 on inside and outside door-plate, and the members such as edge sealing spare 14 of being located at inside and outside door-plate 11,12 both sides respectively, so that labeled door 1, can be outside inside and outside door-plate 11,12 with high thermal isolation that the scene of a fire produced.But no reinforcing devices in the inside and outside door-plate of labeled door 1 in the past 11,12 very easily make door-plate ftracture because of expanded by heating under the HTHP of the scene of a fire or are subjected to pushing, clashing into and damage of external force, so, the overall construction intensity deficiency.

As shown in Figure 2, another kind of labeled door 2, it mainly includes an internal hilar plate 21, an external door panel 22, a plurality of be oppositely arranged in twos in, external door panel 21,22 reinforcement frame 23, and in being installed in, external door panel 21, the edge sealing spare of 22 both side edges 24 members such as grade, in, external door panel 21,22 separated by reinforcement frame 23 to be formed with accommodation space 25, and in the accommodation space 25 and fill out and be provided with fire proofing material 26, simultaneously, these 23 on reinforcement framves facing each other are provided with an insulating board 27, and establish part 28 by spiral shell reinforcement frame 23 facing each other is located by connecting, moreover, reinforcement frame 23 with in, external door panel 21,22 also are provided with fire proofing material 26, and by interior, external door panel 21,22 set reinforcement framves 23 make labeled door 2 have certain structure intensity, and can reach the purpose of heat insulation and heat control.But, in the labeled door 2, external door panel 21,22, though be provided with a plurality of reinforcement framves 23, can make labeled door 2 have stronger structural strength, yet, under the HTHP in the scene of a fire, ignore pushing or impact that each section of surface of labeled door 2 may bear, and can not be chosen in the stressed position of emphasis reinforcement intensity in the door-plate, only in door-plate, equidistantly install the reinforcement frame, its practical benefit is not high, moreover, in the labeled door 2, by reinforcement frame 23 accommodation space 25 that forms that separates, be disconnected air-tight state, so be subjected to high when hot, air meeting Yin Gaowen in the labeled door 2, and increase pressure, the air that causes expanded by heating is by inside in the accommodation space 25, external door panel 21,22 extruding, cause labeled door 2 in, external door panel 21,22 the explosion metaboly takes place easily, and in addition, the air of HTHP must conduct to outside the scene of a fire via the labeled door 2 of explosion distortion in the scene of a fire, and make labeled door 2 lose the effect of original heat insulation and heat control, and then directly threaten the life that is in the inside and outside personnel of labeled door.

The purpose of this utility model is to provide a kind of labeled door that can effectively intercept scene of a fire high temperature.

For achieving the above object, the utility model is taked following technical measures:
