Description
Technical field
The invention belongs to FPE technical fields, and in particular to a kind of fire-proof wooden door.
Background technique
Fire resistant doorsets refer to is able to satisfy the door that fire stability, integrality and thermal insulation require within a certain period of time.It is to set
There are the fire protection separators of certain fire resistance in fire protection interval, emergency staircase, vertical shaft etc..Fire resistant doorsets, which remove, to be had commonly
Outside the effect of door, has the function of preventing fire spreading and flue gas diffusion, the sprawling of the intensity of a fire can be prevented within a certain period of time, really
Protect evacuating personnel.
There are many kinds of classes in fact for fire resistant doorsets.Mainly there are fire-proof wooden door, fire resistance steel door, the fire prevention of steel wood by material point
Door, other fire resistant doorsets etc..Fire-proof wooden door, which refers to, makees doorframe, door leaf skeleton, door skin with fire retardant timber or fire retardant timber-work.
Fire resistance steel door refers to is filled if packing material in door leaf to people with steel material production doorframe, door leaf skeleton and door skin
The nontoxic fire-proof heat-insulating material of body, and it is equipped with the door with certain fire resistance composed by fire prevention Hardware fitting.Steel wood
Matter fire resistant doorsets refer to steel and fire retardant wood materials or fire retardant timber-work production doorframe, door leaf skeleton, door skin.Other materials
Matter fire resistant doorsets refer to using in addition to steel, fire retardant timber or fire retardant timber-work inorganic incombustible material or part using steel,
Fire retardant timber, fire retardant timber-work make doorframe, door leaf skeleton, door skin, if packing material in door leaf, fill to human body
Nontoxic fire-proof heat-insulating material, and it is equipped with the door with certain fire resistance composed by fire prevention Hardware fitting.
Component part of the fire-proof wooden door as firewall, in addition to fire endurance, itself also should be nonflammable material.And
The finishing material of " fire-proof wooden door general technical specifications " on the door has no requirement." steel, fire-proof wooden door product form are recognized
Detailed rules and regulations can be supplemented " Article 3 regulation, fire-proof wooden door manufacturing enterprise must be equipped with fire-retarding of wood processing equipment.But since part is raw
Producing in the technological document that enterprise submits in factory's certification and type inspection certification claims timber not carry out flame retardant treatment, therefore is formed
A kind of understanding, i.e., using broad-leaved wood production fire resistant doorsets when, timber does not need to carry out flame retardant treatment.The formulation is to wooden fire prevention
The quality surveillance of door and fair market competition are very harmful.It's safe to say, timber is without flame retardant treatment, and do not have to anti-
Fiery coating or incombustible material are protected, and the requirement of first class fire resistant doorsets is not achieved in the fire endurance of fire resistant doorsets certainly.According to as follows:
The timber average combustion speed that Europe uses in timber structure Strength co-mputation is used for structural timber 0.7mm/min, interior decoration material
Broadleaf 0.5mm/min, softwood 0.6mm/min (fire surface is plumbness), the combustion of wood that Japanese architecture design uses
Charing rate is 0.6mm/min.The thickness of fireproof door leaf frame material is usually 35mm or so, with the burning charcoal of 0.6mm/min
Change speed to calculate, 60min is just all burnt.Fire resistant doorsets play the role of positive pressure when detecting, while bearing to be self-possessed, when the thickness of timber
When less than 10mm, fire resistant doorsets will lose integrality and thermal insulation.The data of Japan shows structure and thickness and the country when door
When fire-proof wooden door is identical, the requirement of 0.5h is met with the fire resistant doorsets fire endurance that unseasoned timber makes, with flame retardant treatment collection
The fire resistant doorsets fire endurance of production of becoming a useful person meets the requirement of 1.0h.
Summary of the invention
It is an object of the present invention to solve the deficiency of the existing technology and provide a kind of wooden fire prevention for meeting fire protection requirement
Door.
The present invention is achieved by the following technical solution:
A kind of fire-proof wooden door is made of doorframe, door-plate and door closer, and the doorframe is L-shaped structure, and doorframe is by reality
Wooden frame and protruding portion composition, the protruding portion are followed successively by the first flame-retardant layer, fire-proof plate layer and the second flame-retardant layer from inside to outside；It is real
The side wooden frame Ying Men is equipped with anti-plume, and the side protruding portion Ying Men is equipped with anti-collision adhesive tape；The door-plate is longitudinally disposed by two
First skeleton, four the second skeletons being laterally arranged, the fire prevention perlite being filled between bracket and panel composition；The face
Plate includes front panel and rear panel, and front panel and rear panel are two layers, from outside to inside respectively flame-retardant plywood and fire-proof plate；
The door-plate is arranged on doorframe by hinge for fireproof, and door closer movable end is arranged at the top of door-plate, and fixing end is arranged in door
Arch；Fire-proof lock is additionally provided on the door-plate.
The material of first flame-retardant layer and the second flame-retardant layer is for China fir, with a thickness of 8mm.
The fire-proof plate layer is made of the medium density fibre board (MDF) that threeply degree is 5mm.
The flame-retardant plywood with a thickness of 3mm.
The fire-proof plate is the reinforced fireproof plate with a thickness of 5mm.
The length and width of first skeleton is respectively 60mm and 36mm, and the length and width of the second skeleton is respectively
36mm and 30mm.First skeleton and the second skeleton are all made of China fir.
The anti-plume is plug-in type Smoke prevention sealing strip.
PVC film is coated on the flame-retardant plywood.
Aluminium fastening wire is offered on the flame-retardant plywood.
It is carved on the flame-retardant plywood and is painted with modelling pattern.
Compared with prior art, the present invention is used by the flame-retardant plywood of PVC film processing as panel, and fire protecting performance is more
It is good.Main material using China fir as skeleton and doorframe, regulation that meet national standards.Fire resistant doorsets of the invention also have door
The characteristics of plate edge sealing is smooth, seamless, without chamfering, meets the safety standard of fire resistant doorsets.Fire resistant doorsets of the invention are anti-using plug-in type
