The utility model discloses the application is anticipated and is being provided a water -cooled strengthens preventing fire door to solve the problem that cooling effect not good of present water -cooling type fireproof door to the door plant.
Description
Technical field
Present patent application relates to a kind of water-cooled and strengthens labeled door.
Background technology
Labeled door refers to the door that can meet fire stability, integrality and thermal insulation within a certain period of time and require.It is located between fire compartmentation, fire separation thing that emergency staircase, vertical shaft etc. have certain refractoriness.Labeled door, except the effect with common door, has more the effect stoping fire spreading and flue gas diffusion, can stop spreading of the intensity of a fire within a certain period of time, guarantee evacuating personnel.In traditional labeled door, labeled door is all stop spreading of the intensity of a fire by the back-fire relief heat-blocking action of fireproof door plate.But, because mostly fireproof door plate is to adopt steel plate to make.When the intensity of a fire is larger, the high temperature of generation can make fireproof door plate damaged, even melts, loses the protective effect to crowd.
In order to solve the problem, in prior art, normally water pipe is set on doorframe or door-plate, be lowered the temperature to door-plate by the mode of shower water, and stop spreading of the intensity of a fire.
But, due to all standing adopting the mode of shower water can not ensure end of door plate.Secondly, during shower water, because the time of contact of current and door-plate is short, cause door-plate cooling-down effect bad.Above 2 make water-cooling fire door of the prior art cannot end of door plate effective temperature-reducing.
Utility model content
Present patent application is intended to provide a kind of water-cooled to strengthen labeled door, with the problem that the cooling-down effect solving existing water-cooling fire door end of door plate is bad.
Water-cooled in this programme strengthens labeled door, and base case is: comprise doorframe, door-plate, and described door-plate is connected by door hinge with doorframe; Cooled plate is provided with in described door-plate; The inwall of described cooled plate and door-plate outdoor wall forms water-cooled layer, and the side wall surface that the bottom of described water-cooled layer is positioned at door-plate is provided with inlet opening, and the inwall of described door-plate outdoor wall is provided with vertical reinforcing rib, and the height of described reinforcing rib is less than the thickness of water-cooled layer; The outdoor wall top of described door-plate is provided with the weep hole that a row is evenly arranged.
Operating principle and beneficial effect: during breaking out of fire, should by inlet opening to labeled door water-filling, and after current enter water-cooled layer, directly contact with door-plate wall, end of door plate cools.When the water level in water-cooled layer raises behind the position arriving weep hole gradually, outdoor is flow to by weep hole, and stop the spreading to indoor of fire, in addition, arranging of reinforcing rib can play the effect of reinforcement by end of door plate itself, contact area during heat exchange can also be increased, improve the efficiency of end of door plate cooling.So this programme is comprehensively lowered the temperature by the water-cooled layer end of door plate in door-plate, and increases the time of contact of water and door-plate, is increased the area of heat exchange by reinforcing rib, improve the effect of end of door plate cooling in water-cooling fire door.
Scheme 2, as the improvement to base case, is provided with fireprotection layer between described cooled plate and the indoor wall of door-plate.Advantage is, can further caloric restriction to the transmission of indoor.The safety of guarantee personnel.
Scheme 3, as the improvement to base case, described reinforcing rib is evenly arranged on the direction of door-plate width.Advantage is, makes the cooling-down effect of current end of door plate even, the situation that the door-plate that there will not be heat to concentrate to cause is local melting.
Scheme 4, as the improvement to base case, described doorframe is trapezoidal doorframe.Advantage is, can improve the effect of labeled door Smoke prevention and sound insulation.
Scheme 5, as the improvement to scheme 4, the closed place of described doorframe and door-plate is provided with sealing mat.Advantage is, improves the effect of labeled door Smoke prevention and sound insulation further.
Accompanying drawing explanation
Fig. 1 is the structural representation that present patent application water-cooled strengthens labeled door embodiment.
Detailed description of the invention
Below by detailed description of the invention, present patent application is described in further detail:
Reference numeral in Figure of description comprises: inlet opening 10, cooled plate 20, water-cooled layer 30, reinforcing rib 40, fireprotection layer 50, door-plate 60, weep hole 70, doorframe 80.
Embodiment 1
As shown in Figure 1, water-cooled strengthens labeled door, and comprise doorframe 80, door-plate 60, door-plate 60 is connected by door hinge with doorframe 80.Be provided with cooled plate 20 in door-plate 60, described cooled plate 20 forms water-cooled layer 30 with the inwall of the outdoor wall of door-plate 60, and the side wall surface that the bottom of water-cooled layer 30 is positioned at door-plate 60 is provided with inlet opening 10.The inwall of the outdoor wall of door-plate 60 is provided with vertical reinforcing rib 40, and the height of reinforcing rib 40 is less than the thickness of water-cooled layer 30.The outdoor wall top of door-plate 60 is provided with the weep hole 70 that a row is evenly arranged.
In addition, in the present embodiment, fireprotection layer 50 is provided with between cooled plate 20 and the indoor wall of door-plate 60.Advantage is, can further caloric restriction to the transmission of indoor.The safety of guarantee personnel.Reinforcing rib 40 is evenly arranged on the direction of door-plate 60 width.Advantage is, makes the cooling-down effect of current end of door plate 60 even, the situation that the door-plate 60 that there will not be heat to concentrate to cause is local melting.Doorframe 80 is trapezoidal doorframe 80.Advantage is, can improve the effect of labeled door Smoke prevention and sound insulation.Doorframe 80 is provided with sealing mat with the closed place of door-plate 60.Advantage is, improves the effect of labeled door Smoke prevention and sound insulation further.
During breaking out of fire, should give labeled door water-filling by inlet opening 10, after current enter water-cooled layer 30, directly contact with door-plate 60 wall, end of door plate 60 cools.When the water level in water-cooled layer 30 raises behind the position arriving weep hole 70 gradually, outdoor is flow to by weep hole 70, and stop the spreading to indoor of fire, in addition, arranging of reinforcing rib 40 itself can play the effect of reinforcement by end of door plate 60, contact area during heat exchange can also be increased, improve the effect that end of door plate 60 is lowered the temperature.
Above-described is only the embodiment of present patent application, and in scheme, the general knowledge such as known concrete structure and/or characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from present patent application structure, some distortion and improvement can also be made; these also should be considered as the protection domain of present patent application, and these all can not affect effect and the practical applicability of present patent application enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in manual etc. record the content that may be used for explaining claim.
