Abstract
The invention discloses a fireproof door, and belongs to the technical field of fireproof doors. The fireproof door comprises a door leaf, a fireproof lock, a fireproof door handle, fireproof hinges, a door frame and an electromagnetic induction type fireproof door closer. The door frame of a double-L-shaped structure comprises a front contact portion, a middle connection portion and a rear contact portion. The fireproof door has the advantages that the fireproof door is simple in structure and good in fireproofing and heat insulation effects; door frame deformation is prevented, and a gap between the door leaf and the door frame is further reduced; the fireproof door has high sensitivity and is closed timely, so that fire spread and smoke diffusion are stopped effectively.
Description
Technical field
The present invention relates to labeled door technical field, particularly relate to the labeled door that a kind of fireproof performance is excellent.
Background technology
Labeled door is the important component part of structural fire protection measure, and in building, fire escape all needs to arrange labeled door in fire compartmentation place.Labeled door all can deform in processing, installation, use, and heat more will be out of shape, and this makes door leaf and doorframe gap become large or diminish, and is unfavorable for closed labeled door or effectively stops fire spreading.Meanwhile, the labeled door closure function of rapid sensitive is also required for fire line improves.
Summary of the invention
For overcoming problems of the prior art, the invention provides a kind of not yielding, labeled door that fireproof performance is good.
The invention provides a kind of labeled door, comprise door leaf, Fire-proof lock, labeled door handle, hinge for fireproof, it is characterized in that, also comprise the doorframe with the double L-shaped structure that front contact site, middle connecting portion and rear contact site are formed, and induction fire-proof door closer.
This labeled door utilizes double L-shaped structure fire doorframe, doorframe is wrapped up the compact siro spinning technology that door leaf realizes doorframe and door leaf, reduces gap between door leaf and doorframe, improves labeled door refractoriness.Induction fire-proof door closer simultaneously, fire prevention inductive effects is sensitive, makes fast and closes an action, further increase fire protection efficiency.
As preferably of the present invention, described front contact site, described middle connecting portion and described rear contact site form the recess with seal groove.
As preferably of the present invention, described seal groove has insulation hole.
As preferably of the present invention, described door frame surface has fire resistant coating.
As preferably of the present invention, described fire resistant coating is the inorganic coagulation material coating of 12-16mm.
As preferably of the present invention, in described front contact site and described rear contact site, be provided with iron connector.
As preferably of the present invention, described front contact site, described middle connecting portion, described rear contact site are filled with heat-insulating, fire-preventing cotton.
As preferably of the present invention, described fire-proof door closer comprises signal detecting part, control assembly and electromagnetism and closes door bolt.
The present invention has following beneficial effect:
Fireproof door structure of the present invention is simple, and fire prevention, good heat-insulation effect, prevent door frame distortions, reduces gap between door leaf and doorframe further, and it is highly sensitive that door is closed in fire prevention simultaneously, and closed labeled door, effectively stops that fire spreading, flue gas spread in time.

Detailed description of the invention
As Fig. 1, labeled door of the present invention comprise doorframe 1, door leaf 2, Fire-proof lock 3, labeled door 4, hinge for fireproof 5 and fire-proof door closer.Described doorframe 1 comprises front contact site 11, middle connecting portion 12, rear contact site 13.Described doorframe 1 surface scribbles fire resistant coating, namely on described front contact site 11, described middle connecting portion 12, described rear contact site 13, all scribbles fire resistant coating.In order to improve fireproof performance, this fire resistant coating can be inorganic coagulation material coating, and as the mixture such as magnesia, magnesium chloride solution, low fire-retardant, the distortion-free feature of this coating effectively improves the fire line of doorframe.Simultaneously, the heat conduction length that also can increase fireproof door frame 1 improves doorframe fire line further, then arrange described fire resistant coating and described front contact site 11 or described rear contact site 13 and form the thick heat conduction length of 100-120mm, as preferably, wherein said coating layer thickness is 12-16mm.In addition, in described front contact site 11 with described rear contact site 13, being provided with iron connector, in order to reinforce described fireproof door frame, by strengthening doorframe intensity, supporting fireproof door frame fire resistance period long.
Described front contact site 11, described middle connecting portion 12, described rear contact site 13 three formation have spacing distance and the double L-shaped structure be set up in parallel.This doorframe is connected with door leaf, utilizes bilateral L-type to wrap up door leaf, reduces the gap between doorframe and door leaf, improve door leaf and doorframe seal, can be fastenedly connected with door leaf.
Described doorframe 1 also comprises the recess 14 be made up of described front contact site 11, described middle connecting portion 12 and described rear contact site 13, and in order to improve the fireproof performance of doorframe 1 and door leaf 2 further, described recess 14 offers seal groove 2 with door leaf 2 junction.Described seal groove 2 can be angle-style, also can be circular arc type.Further, pre-buried fireproofing glue strip can be set in described seal groove 2, or Smoke prevention adhesive tape, directly stick on described fire resistant coating.Also insulation hole can be set in described seal groove 2, evenly be arranged in described seal groove, while reducing doorframe thickness, improve the effect of heat insulation of doorframe.In addition, described front contact site 11, described rear contact site 13, described middle connecting portion 12 are filled with heat-insulating, fire-preventing cotton, to improve doorframe effect of heat insulation further.
Described fire-proof door closer 6 comprises signal detecting part, control assembly and electromagnetism and closes door bolt.Described signal detecting part can be smoke-detectors, temperature detector etc., in order to detect breaking out of fire situation, this signal detecting part can be arranged on the wall or on doorframe, when doorframe be metal form time, being arranged on temperature detector on doorframe can temperature sensor fast.Described control assembly comprises control chip, induction coil, and when temperature is higher than induction coil energising during preset temperature in control assembly, the electromagnetism by described induction coil effect closes door bolt and drives labeled door closed action.
When a fire, fireproof door closer 6 closes labeled door in time, and escape personnel firmly can also pin labeled door by Fire-proof lock 4.When fire spreading, expansion fastener, by high-temperature expansion, by door leaf and doorframe compact siro spinning technology, effectively prevents door frame distortions, improves labeled door fireproof performance.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
