Abstract
The utility model relates to a door, especially a fire door is prevented to multilayer. Should prevent that fire door included the gate and locates the sectional type door plant in the door frame, the sectional type door plant passes through the bulkhead to be separated, the door plant be six layer structures, six layers according to from interior to exterior be interior door plant, first flame retardant coating in proper order, layer, sound absorbing layer, second flame retardant coating and outer door panel finalize the design, first flame retardant coating, sound absorbing layer and second flame retardant coating extend in to door frame and bulkhead. The utility model discloses a fire door is prevented to multilayer is equipped with first flame retardant coating and second flame retardant coating, has strengthened fireproof effect greatly, the setting on design layer, difficult emergence is warp after the door body is heated, does not influence the normal use of door, the setting of sound absorbing layer makes the effect reinforcing of giving sound insulation, is difficult for receiving the interference of noise, guarantees the living environment of equanil.
Description
Technical field
The utility model relates to a kind of door, especially a kind of multi-layer fireproofing door.
Background technology
Along with the progress of society, the development of living standards of the people, the consciousness of people to fire-fighting is also more and more paid attention to, and in house finishing, a lot of fire fighting device is also applied wherein.Such as: fireproof kitchen cabinet, labeled door, fire-retardant paint etc.
Labeled door is the door with fire stability, integrality and thermal insulation made with applied fireproofing, be mainly used in the places such as the fire wall opening of building fire protection subregion, staircase access, evacu-ation walk, pipeline well head, usually pass through for personnel, can play when breaking out of fire and stop propagation of flame and prevent combustion product gases from flowing, and play sealing when positive air supply system work.Labeled door should have the obstruct intensity of a fire and burn the effect spread with flue gas diffusion, has strict demand, once breaking out of fire, can stop spreading of the intensity of a fire within a certain period of time, guarantee evacuating personnel from closure, anti-flammability, thickness.Labeled door serves extremely important effect in prevention fire spread.Labeled door is last pipe protection umbrella preventing fire spread, simultaneously as last one barrier ensureing resident's security of the lives and property.
Existing door, comprises upper and lower two-layer door-plate, between upper door-plate and lower door-plate, be filled with fire-proof heat-insulating material, such door flameproof effect is bad, and soundproof effect is poor, and being heated, back door shape is easily out of shape again, owing to there is such technical problem, therefore, be necessary to improve existing door.。
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of multi-layer fireproofing door.
To achieve these goals, the utility model adopts following technical scheme:
This multi-layer fireproofing door, comprise doorway and be located at the segmented door-plate in doorframe, segmented door-plate is separated by bulkhead, described door-plate is six Rotating fields, comply with for described six layers and be followed successively by internal hilar plate, the first fireprotection layer, setting layer, sound absorbing layer, the second fireprotection layer and external door panel from the inside to the outside, the first described fireprotection layer, sound absorbing layer and the second fireprotection layer extend in doorframe and bulkhead.
Preferably, the first described fireprotection layer and the second fireprotection layer are all meta-aramid fibers layer of cloth.
Preferably, described setting layer is gauze wire cloth or steel plate.
Preferably, described sound absorbing layer is polyurethane foam board or rock wool.
Preferably, described setting layer thickness is 5mm-10mm, and described sound absorbing layer thickness is 10mm-20mm.
Preferably, described six layers bonding successively forms.
Owing to have employed said structure, multi-layer fireproofing door of the present utility model is provided with the first fireprotection layer and the second fireprotection layer, greatly strengthen flameproof effect; The setting of setting layer, not easily deforms after door body is heated, and does not affect the normal use of door; The setting of sound absorbing layer, makes soundproof effect strengthen, and is not subject to the interference of noise, ensures peaceful living environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
As shown in Figure 1, the multi-layer fireproofing door of embodiment of the present utility model comprises doorway and is located at the segmented door-plate in doorframe, segmented door-plate is separated by bulkhead, such as general door body is generally separated into two-part door body by the bulkhead of frame and centre, door-plate in rest in doorframe is six Rotating fields, comply with for described six layers and be followed successively by internal hilar plate 1, first fireprotection layer 2, setting layer 3, sound absorbing layer 4, second fireprotection layer 5 and external door panel 6 from the inside to the outside, the first fireprotection layer 2 simultaneously, sound absorbing layer 4 and the second fire prevention 5 layers extend in doorframe and bulkhead.First fireprotection layer 2, sound absorbing layer 4 and the second fire prevention 5 layers extend the fireproof performance that effectively can improve doorframe and bulkhead place in doorframe and bulkhead, simultaneously due to the existence of doorframe and bulkhead, setting layer and inside and outside door-plate can be saved, the object of saving material can be reached simultaneously
In the present embodiment, the first described fireprotection layer 2 and the second fireprotection layer 5 are all meta-aramid fibers layer of cloth.
In the present embodiment, described setting layer is gauze wire cloth or steel plate.
In the present embodiment, described sound absorbing layer is polyurethane foam board or rock wool.
In the present embodiment, described setting layer thickness is 5mm-10mm, and described sound absorbing layer thickness is 10mm-20mm.
In the present embodiment, described six layers bonding successively forms.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model manual and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
