The utility model discloses a fire exit door's mounting structure, door plant can keep the state opened under normal condition, make things convenient for the pedestrian to pass through, then outage accessible time makes the door plant to close, prevent that the intensity of a fire from stretching when the conflagration breaing out, in addition, the elastomeric element in the door -hinge that restores to the throne that it has also can in time close the door plant in the malfunctioning circumstances of electromagnetic system, and dual guarantee is safe in utilization.
Description
Technical field
The utility model relates to fire fighting equipment technical field, is specifically related to a kind of mounting structure of fire exit door.
Background technology
In the commercial buildings such as present hotel, apartment, generally public corridor can be divided into two regions, i.e. fire compartmentation, labeled door therefore generally can be adopted to guarantee safety during fire.Traditional fire exit door adopts and usually adopts the open and close realizing self in two ways, and one is exactly utilize the door closer be arranged on labeled door to realize; Another kind is then install electric energy releasing device on labeled door.
But above-mentioned two kinds of modes all also exist weak point, as adopted door closer, as long as pedestrian encounters door because of carelessness, door will be closed, and causes the frequent open and close of labeled door, easily makes door closer damage.In addition, adopt electric energy releasing device, long-term use causes spring fatigue in this device or oil hydraulic system leakage of oil, easily malfunctioning, causes its labeled door cisco unity malfunction.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is the mounting structure providing a kind of fire exit door, and when breaking out of fire, door-plate can close in time, uses safer.
For achieving the above object, the utility model adopts following technical scheme:
A kind of mounting structure of fire exit door, comprise door-plate and body of wall is installed, door-plate is articulated in by a reset door-hinge and installs on body of wall, is provided with elastomeric element in this reset door-hinge, and this elastomeric element is for providing one by door-plate towards the elastic stress of pressing away from the top, direction of installing body of wall; One end of elastomeric element is fixed on door-plate, and the other end of elastomeric element is fixed in be installed on body of wall; Install body of wall and be provided with electromagnet, door-plate corresponds to the position of electromagnet and is provided with magnet, magnet door-plate be close to body of wall is installed time and electromagnet magnetic attracting; Be provided with a constant close contact linked with external control circuit in electromagnet, this constant close contact is serially connected with in the current supply circuit of electromagnet.
Preferably, body of wall is installed to be made up of aerated bricks.
Preferably, the surface of installing body of wall is provided with fireproofing wood panel layer.
Preferably, the edge bag of door-plate is provided with stainless steel edge cover strip.
The beneficial effects of the utility model are:
Compared to prior art, the mounting structure of fire exit door of the present utility model, its state door-plate can being held open under normal circumstances by the magnetic absorption of electromagnet and magnet, facilitates pedestrian to pass through, then can door-plate cut out power-off in time when breaking out of fire, prevent fire spreading; In addition, door-plate also can cut out in the situation that electromagnetic system is malfunctioning by elastomeric element in the reset door-hinge that it has in time, double shield, use safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross-sectional view of the present utility model.
Wherein, 10, body of wall is installed; 11, electromagnet; 12, fireproofing wood panel layer; 20, door-plate; 21, stainless steel edge cover strip; 22, reset door-hinge.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
The mounting structure of a kind of fire exit door as shown in Figure 1 and Figure 2, comprises door-plate 20 and installs body of wall 10, and door-plate 20 is articulated in by a reset door-hinge 22 and installs on body of wall 10, facilitates the folding of door-plate 20.Specifically in reset door-hinge 22, be provided with an elastomeric element, and this elastomeric element is for providing one by door-plate 20 towards the elastic stress of pressing away from the top, direction of installing body of wall 10.
Simultaneously, above-mentioned installation body of wall 10 is also provided with electromagnet 11, accordingly, the position corresponding to electromagnet 11 at door-plate 20 arranges magnet, so when electromagnet 11 is energized, door-plate 20 is close to when installing body of wall 10 and just can be adsorbed on because magnetic is attracting on installation body of wall, and the state that door-plate 20 can be held open under normal circumstances, facilitates pedestrian to pass through.
And because door-plate 20 is when being adsorbed on installation body of wall 10, above-mentioned elastomeric element is confined state, therefore when powering-off state appears in breaking out of fire, electromagnet 11 loses magnetism, door-plate 20 towards movable away from the direction of installing body of wall 10 under the effect of above-mentioned elastomeric element, can make door-plate 20 cut out in time, prevents fire spreading, double shield, use safety.
In addition, constant close contact can be provided with in above-mentioned electromagnet 11, this constant close contact and external control circuit link, namely be kept closed in the normal situation of power supply, and when dead electricity, this constant close contact of external control circuit coordinated signals disconnects, and this constant close contact is serially connected with in the current supply circuit of electromagnet 11.So when fire occurs, when fire fighting system receives the report for police service, external control circuit disconnects civil power by making constant close contact in time, thus makes electromagnet 11 dead electricity, and then electromagnet 11 loses magnetism, and door-plate 20 can be closed in time.
Preferably, installing body of wall 10 can be made up of aerated bricks, because of the high temperature resistant preferably of aerated bricks and heat-proof quality, better can adapt to hot environment, enhance product performance when fire occurs.Further, be provided with fireproofing wood panel layer 12 on the surface of installing body of wall 10, because wooden facing of preventing fires has flame retardancy, reduce and the damage of body of wall 10 when fire occurs is installed.
Preferably, stainless steel edge cover strip 21 can be established at the edge bag of above-mentioned door-plate 20, reinforce the structure of door-plate 20.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
