Description
Technical field
The utility model relates to fire resistant doorsets technical fields, and in particular to a kind of sound insulated fire door.
Background technique
Fire resistant doorsets are the important components of structural fire protection measure, and fire escape is both needed to be arranged at fire compartment in building
Fire resistant doorsets, with the rapid rising of building trade, the manufacturing technology of fire resistant doorsets also further develops and mature, the quality of fire resistant doorsets
As the necessary factor of every family selection, traditional fire resistant doorsets are generally made of steel or wood, are mounted on wall, door leaf peace
On doorframe, steel door is typically provided in the case where must supporting fire resistant sprawling one hour or more；And wooden door is usually more
It is easy to be inclined by fire and attack, thus with needing on fire resistant one hour door below of sprawling.However either existing steel
Therefore fire resistant doorsets processed or wooden fire resistant doorsets, the high request that fire protecting performance is also able to satisfy far away modern industry sphere of life are opened
Hair fire protecting performance is more excellent, and the high high-performance fire-resistant door of fire-protection rating is a significant and very necessary job；It is anti-
Vent can all deform in processing, installation, use, and heat will more deform, this makes the gap of door leaf and doorframe become larger
Or become smaller, be unfavorable for being closed fire resistant doorsets or effectively prevent fire spreading, meanwhile, existing Fireproof door structure is complicated, and general
There is this one-side function of preventing fires, the soundproof effect of fire resistant doorsets is poor, and the basic function interval sound function of door is also particularly significant,
Sound is easy to be propagated by fire resistant doorsets, to influence the routine use of user.
Utility model content
In view of the deficienciess of the prior art, that the purpose of this utility model is to provide a kind of soundproof effects is good, fire prevention function
Strong, the moisture-proof door body in place of energy is unlikely to deform and sound insulated fire door with long service life.
The technical solution of the utility model is achieved in that a kind of sound insulated fire door, it is characterised in that: including doorframe,
Door body and fire prevention hinge, the door body are hinged on doorframe by hinge of preventing fires, and the door body includes that interior fire-proof plate and package are set
The outer metal fireproof plate on interior fire-proof plate outer wall is set, is arranged in the interior fire-proof plate along the longitudinal perforation from top to bottom of interior fire-proof plate
There is accommodating chamber, sound absorption noise lowering board and sound insulation and noise reduction plate, the sound absorption noise lowering board and sound insulation drop are respectively arranged in the accommodating chamber
Make an uproar and be provided with the second noise reduction cavity between plate, be provided with the first noise reduction cavity between the sound absorption noise lowering board and interior fire-proof plate, it is described every
Third noise reduction cavity is provided between sound noise reducing plate and interior fire-proof plate, the spacing between the sound absorption noise lowering board and interior fire-proof plate with every
Spacing between sound noise reducing plate and interior fire-proof plate is identical and the spacing is greater than the spacing between sound absorption noise lowering board and sound insulation and noise reduction plate.
By using above-mentioned technical proposal, package is provided with the structure of outer metal fireproof plate on the outer wall of interior fire-proof plate,
The setting in conjunction with wooden structure, improves wooden fire resistant doorsets flameproof effect usually in one hour limit below by metal
System makes internal interior fire-proof plate be in a totally enclosed state, reduce because of caused by the wooden reason of interior fire-proof plate by
The wooden phenomenon appearance of swelling when occurring and is heated of damp phenomenon, enhances the moisture resistance of fire resistant doorsets, moisture is avoided to enter interior fire prevention
Internal fire-proof plate causes to corrode in plate, increases the service life of fire resistant doorsets, without ignition substance and oxidizer, effectively prevents
The sprawling of the intensity of a fire, on the other hand the combination saves the material of metal, and processing and making process is more on the basis of having saved cost
Simply；It is provided with an accommodating chamber in interior fire-proof plate, sound absorption noise lowering board and sound insulation and noise reduction plate are respectively set in accommodating chamber, right
It is anti-by this either from the sound propagated outdoors into door or door introversion is propagated outdoors when the propagation of sound is handled
When vent, respectively by the wood materials sound-absorbing of the sound insulation of outer metal fireproof plate and interior fire-proof plate, and in accommodating chamber the
One noise reduction cavity, sound absorption noise lowering board, the second noise reduction cavity, sound insulation and noise reduction plate and third noise reduction cavity sound insulation and noise reduction after, by fire resistant doorsets institute
The soundproof effect played is expanded to maximum, ensure that the sound insulation function of fire resistant doorsets；Between between sound absorption noise lowering board and interior fire-proof plate
And the spacing identical away from the spacing between sound insulation and noise reduction plate and interior fire-proof plate is greater than between sound absorption noise lowering board and sound insulation and noise reduction plate
Spacing, the effect of the structure is to want to improve sound absorbing power significantly, depends merely on the quality for increasing interlayer, such as increase the thickness of plate
Degree, cannot effectively improve attraction power, and the approach at this moment solved is mainly using double-deck down to multiple sound insulation structure, bilayer knot
Structure plays attenuation to sound transmission, prevents from resonating, and reduces most sound transmission, the utility model provide it is a kind of every
Audio fruit is good, fire-proof function is strong, moisture-proof door body in place is unlikely to deform and sound insulated fire door with long service life.
The utility model is further arranged to: on the doorframe and door body and in the gap at doorframe and door body closure
