SUMMERY OF THE UTILITY MODEL

The utility model provides a fire door is prevented in giving sound insulation has solved the relevant function that prevents fire door and generally only prevent this unilateral of fire, and prevents that fire door's syllable-dividing effect is unsatisfactory, can not reach the problem of the syllable-dividing effect that operational environment required.

The technical scheme of the utility model as follows:

the utility model provides a fire door is prevented in giving sound insulation, includes sound-absorbing layer, outer shell and flame retardant coating, the flame retardant coating wraps up in sound-absorbing layer both sides, the flame retardant coating includes: an inner fireproof layer and an outer fireproof layer, wherein a sound insulation layer is arranged between the inner fireproof layer and the outer fireproof layer,

the outer shell layer covers the fire-proof layer,

the sound absorption layer is a multi-layer or single-layer low-density layered sound insulation structure.

The outer edge of the sound absorption layer is provided with a hard framework, the hard framework is of a rectangular strip structure and is as thick as the sound absorption layer, and the hard framework is wrapped between the fireproof layers together on the sound absorption layer.

And a gap type sound insulation cavity is reserved between the hard framework and the sound absorption layer.

And an expansion sealing layer is arranged between the outer shell layer and the hard framework.

The expansion seal layer extends from one side of the inner wall of the outer shell layer to the other side and covers the outer edges of the inner and outer fire resistant layers.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view of a portion of A in FIG. one;

in the figure: 1. sound absorption layer 2, outer shell layer 3, inner fireproof layer 4, outer fireproof layer 5, sound insulation layer 6, hard skeleton 7, sound insulation cavity 8 and expansion sealing layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive work, are related to the scope of the present invention.

Example 1, as shown in figures 1-2,

a sound insulation fireproof door comprises a sound absorption layer 1, an outer shell layer 2 and a fireproof layer, wherein the fireproof layer is wrapped on two sides of the sound absorption layer 1,

the fire-resistant layer includes: an inner fireproof layer 3 and an outer fireproof layer 4, a sound insulation layer 5 is arranged between the inner fireproof layer 3 and the outer fireproof layer 4,

the outer shell layer 2 covers outside the fireproof layer, and is characterized in that: the sound absorption layer 1 is a multi-layer or single-layer low-density layered sound insulation structure.

The utility model discloses in provide a fire door is prevented in giving sound insulation, be provided with firm outer shell 2, and the flame retardant coating that fire behavior is good, sound absorbing layer 1 is provided with the lamellar sound-insulating structure of multilayer or individual layer low density, and sound absorbing layer 1 has the function of absorption sound vibrations, has promoted sound insulation and fastness. This embodiment adopts inside and outside two-layer fire prevention design, can obtain better fire prevention effect, and puigging 5 is the deadening felt of high density, can the shock attenuation give sound insulation and promote the sound insulation performance of fire door that gives sound insulation. The problem of relevant fire door generally only have this unilateral function of fire prevention, but fire door's syllable-dividing effect is unsatisfactory, does not reach the syllable-dividing effect that operational environment required is solved.

Further, as shown in FIG. 2,

the outer edge of the sound absorption layer 1 is provided with a hard framework 6, the hard framework 6 is of a rectangular strip structure and is the same as the thickness of the sound absorption layer 1, and the hard framework 6 wraps the sound absorption layer 1 between the fireproof layers. The hard skeleton 6 has the same thickness as the sound absorption layer 1, and can improve the firmness and the sound insulation of the door panel.

Further, as shown in FIG. 2,

a gap type sound insulation cavity 7 is reserved between the hard framework 6 and the sound absorption layer 1. The hard framework 6 can provide good support for the door body, so that the door plate is firm and reliable, and the sound insulation effect can be improved by reserving gaps.

Further, as shown in FIG. 2,

an expansion sealing layer 8 is arranged between the outer shell layer 2 and the hard framework 6.

After the expansion sealing layer 8 reaches the expansion temperature, the expansion sealing layer expands at the highest speed, so that gaps are sealed, high-temperature flame and smoke are prevented from spreading, and escape time is strived for escape personnel.

Further, as shown in FIG. 2,

the intumescent sealing layer 8 extends from one side of the inner wall of the outer shell layer 2 to the other and covers the outer edges of the inner and outer fire barrier layers 3, 4. The expansion sealing layer covers comprehensively without leaving a gap, so that the sound insulation performance can be improved, the stability and firmness of the structure can be guaranteed, and meanwhile, after the expansion sealing layer 8 reaches the expansion temperature, the expansion is performed at the highest speed, the gap can be filled better, and the high-temperature flame and smoke dust are prevented from spreading.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
