Description

Fire-proof door

Technical Field

The utility model belongs to building fire prevention field especially relates to a prevent fire door.

Background

At present, the fire protection design requirement is more and more strict, and the requirement on the net size of an evacuation door in the building design fire protection specification is more and more large. In the design, the situation that the width of the door is not large in normal use requirement, but the design evacuation width is large is often met, and for the difference of the design width requirement, if the door opening leaf is large in order to meet the fire protection requirement, the space waste is generated in use, but the fire protection design requirement must be followed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fire door to solve the sparse jumbo size that requires of fire control among the prior art, can open the not high small-size of width requirement when using at ordinary times again, and can realize the problem of switching in the twinkling of an eye under the fire control signal effect.

For solving the technical problem, the utility model discloses the technical scheme who adopts is:

a fireproof door comprises a main door, an auxiliary door, a first door control system and a second door control system, wherein the auxiliary door is a door-in-door arranged on the main door, the main door is connected with the auxiliary door through a hinge, the main door is connected with the first door control system, the auxiliary door is connected with the second door control system, the first door control system and the second door control system are respectively and electrically connected with a fire-fighting linkage controller, the fire-fighting linkage controller transmits signals to the first door control system and the second door control system when in a fire state, the first door control system is closed, the main door is opened, the second door control system is opened, and the auxiliary door is closed; in a daily state, the first access control system is opened, the main door is closed, the second access control system is closed, and the auxiliary door is in an openable state.

And when the second door control system is opened, the automatic door closer acts to close the auxiliary door.

Furthermore, the first door control system is arranged at the top end or the side edge of the main door, and the second door control system is arranged at the top end or the side edge of the auxiliary door.

Further, the fire door switch monitoring device is used for monitoring a fire door switch and is electrically connected with the central control room.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has:

the utility model provides a pair of prevent fire door, when the conflagration breaing out, behind the fire signal that fire control linkage controller sent, main door is opened to first access control system, and vice door is closed to second access control system. Under daily conditions, the main door is normally closed, and the auxiliary door is in an openable state through the second access control system. Therefore, different requirements of the width of the door under the daily and fire conditions can be realized, and the instant switching is realized under the action of receiving the fire-fighting signal, so that the fire-fighting requirement is met.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Fig. 1 to fig. 3 show a specific embodiment of the fire door of the present invention, as shown in fig. 1, the fire door comprises a main door, an auxiliary door, a first door control system and a second door control system, wherein the auxiliary door is a middle door installed on the main door, the main door is connected to the auxiliary door through a hinge, the main door is connected to the first door control system, the auxiliary door is connected to the second door control system, the first door control system and the second door control system are respectively electrically connected to a fire protection linkage controller, when in a fire disaster state, the fire protection linkage controller transmits a signal to the first door control system and the second door control system, the first door control system is closed, the main door is opened, the second door control system is opened, and the auxiliary door is closed; in a daily state, the first access control system is opened, the main door is closed, the second access control system is closed, and the auxiliary door is in an openable state. Because the main and auxiliary door is according to the state that fire control linkage controller is conflagration promptly, the main and auxiliary door is not opened simultaneously or is closed, realize the different requirements of width of door under daily and the conflagration state, and realize switching in the twinkling of an eye under the effect of receiving the fire control signal, satisfy the fire control requirement, the auxiliary door passes through hinge connection with the main door, make the auxiliary door pass through the hinge can open in or open outward smoothly, in this embodiment, the auxiliary door is inwards opened when using at ordinary times, as shown in fig. 3, can reduce the influence to the corridor after the auxiliary door is opened.
