Abstract
The utility model provides a magnetic type floor spring fireproof door which comprises a door leaf, a door frame and a floor spring, wherein thermal dilation sealing strips are fixed between the door leaf and the door frame; the floor spring is of a non-positioned floor spring; a magnetic plate with an electromagnetic door stopper is fixedly installed at the back side of the door leaf; an electromagnet of the electromagnetic door stopper is fixedly installed at a corresponding wall or a ground; and the electromagnet is communicated with a firefighting control center or a firefighting detector. At a normal state, the electromagnet absorbs the magnetic plate on the door leaf so that the door is at the constantly opened state, the requirement that people can go out and go in conveniently is met; however when a fire disaster happens, the firefighting control center can cut off the control voltage or the firefighting detector automatically cuts off the voltage after detecting a fire disaster signal, the electromagnetic door stopper is powered off so as to release the door leaf, and then the fireproof door is closed, so that the firefighting control center can master and control the fireproof isolation situation at the area, thereby being beneficial for the deployment and the control to the fire disaster.
Description
Technical field
The utility model relates to a kind of floor spring fireproof door, especially a kind of magnetic-type floor spring fireproof door.
Background technology
When breaking out of fire in highrise building, the intensity of a fire is easy to spread, and causes a serious accident, and in order to reduce the scope of fire propagation, the common defensive measure of taking is that labeled door is installed; In the prior art, in order to make the door that is provided with floor spring have fire-proof function, periphery at door leaf is provided with the thermal expansion weather strip corresponding with doorframe, leave the slit between thermal expansion weather strip and the doorframe, when fire occurs, thermal expansion weather strip expanded by heating, thereby the sealing between realization door leaf and the doorframe; For floor spring fireproof door, floor spring can adopt positioningly spring, namely opens under the state that rear door leaf then is positioned often to open, and also can adopt the delocalization floor spring, and namely opening rear door leaf can automatically reset; But though which kind of adopts, all there is certain problem: as, when adopting the delocalization floor spring, door leaf is in normally off, and the routine that is not easy to personnel is current, and often switch easily causes artificial damage; And when adopting retainer spring, door leaf is under the normally open, in case breaking out of fire, as have no time to attend to and close door leaf, then labeled door has just lost the effect of isolation and control fire spreading, and labeled door is under uncontrollable state, Fire Services Communication Centre also can't be grasped the fire prevention isolated instances in this zone, thereby has affected deployment and control to the condition of a fire.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of magnetic-type floor spring fireproof door, can in time control and grasp the switching situation of labeled door, is convenient to deployment and the control of the condition of a fire.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of magnetic-type floor spring fireproof door, comprise door leaf, doorframe and floor spring, be fixed with the thermal expansion weather strip between described door leaf and the doorframe, it is characterized in that: described floor spring is the delocalization floor spring, the described door leaf back side is installed with the magnetic plate of electromagnetism door-inhale, the electromagnet that corresponding body of wall or ground are installed with the electromagnetism door-inhale, described electromagnet is communicated with Fire Services Communication Centre or fire fighting detector.
The beneficial effects of the utility model are: the utility model has been installed the electromagnetism door-inhale at normally closed delocalization floor spring door, make it under non-fire condition, can keep normally open, satisfy the requirement of personnel's easy access, and when breaking out of fire, but Fire Services Communication Centre cutting-off controlling voltage or fire fighting detector cut off voltage after detecting fire signal automatically, make electromagnetism door-inhale dead electricity and discharge door leaf, close labeled door.The utility model is conducive to the fire prevention isolated instances that this zone was grasped and controlled to Fire Services Communication Centre so that closing of labeled door is under the controllable state, is convenient to deployment and the control of the condition of a fire.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1 open mode.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of magnetic-type floor spring fireproof door, a kind of magnetic-type floor spring fireproof door, comprise door leaf 1, doorframe 2 and floor spring 3, be fixed with thermal expansion weather strip 4 between described door leaf 1 and the doorframe 2, described floor spring 3 is the delocalization floor spring, and described door leaf 1 back side is installed with the magnetic plate 51 of electromagnetism door-inhale 5, the electromagnet 52 that corresponding body of wall or ground are installed with electromagnetism door-inhale 5, described electromagnet 52 is communicated with Fire Services Communication Centre or fire fighting detector.
Operating principle of the present utility model is: under the normal condition, the electromagnet 52 of electromagnetism door-inhale is charged, and the magnetic plate 51 on can the adhesive door leaf makes the fireproof door leaf location, and door remains on normally open; When meeting the condition of a fire, Fire Services Communication Centre control voltage interruption or fire fighting detector cut off voltage after detecting signal automatically, make electromagnet 52 dead electricity and discharge a body.
The utility model has been installed the electromagnetism door-inhale at normally closed delocalization floor spring door, make it under non-fire condition, can keep normally open, satisfy the requirement of personnel's easy access, and when breaking out of fire, can cut off the power supply again, make electromagnetism door-inhale dead electricity and discharge door leaf, close labeled door, play the effect that the control of isolation burning things which may cause a fire disaster spreads.The utility model is conducive to the fire prevention isolated instances that this zone was grasped and controlled to Fire Services Communication Centre so that closing of labeled door is under the controllable state, is convenient to deployment and the control of the condition of a fire.
