Description

Technical Field

[0001] The utility model relates to the technical field of fireproof doors, in particular to a fireproof door with good sound insulation effect. Background Art

[0002] Fire doors refer to doors that can meet the requirements of fire resistance, integrity and thermal insulation within a certain period of time. They are fireproof partitions with certain fire resistance, such as those installed between fire compartments, evacuation stairwells, vertical shafts, etc. For example, the partition doors of equipment rooms (cylinder rooms, foam stations, etc.) with fixed fire extinguishing devices installed in high-rise civil buildings, ventilation and air conditioning rooms, etc. should use Class A fire doors; the doors on the partition walls of basement rooms where people often stay or there are many combustibles should use Class A fire doors; due to conditions, it is necessary to arrange oil and gas boilers, combustible oil-immersed power transformers, high-voltage capacitors and switches filled with combustible oil in high-rise buildings, and the doors on the partition walls of special rooms should all use Class A fire doors. There are also household doors that are designed with special requirements and must be fireproof, such as the household doors of fire monitoring and command centers, archives and information rooms, and valuables warehouses, which usually use Class A or Class B fire doors. The household doors of high-rise and high-end residential buildings often use fireproof and anti-theft doors. Fire doors are an important component of fire-fighting equipment and an important part of social fire prevention. Fire doors should be installed with fire door closers or door closing devices that allow normally open fire doors to automatically close the door leaves in the event of a fire (except for use in special areas, such as pipe well doors).

[0003] After searching, the Chinese patent with publication number: CN203669665U discloses a fireproof door, aiming to provide a fireproof door with sound-absorbing function and good appearance. The key points of its technical solution are a fireproof door, including a door leaf and a door frame, the door leaf includes a flame-retardant layer and two wood layers, the flame-retardant layer is located between the wood layers, the flame-retardant layer is provided with a perlite layer, an asbestos layer and a gypsum layer in sequence from both outer surfaces inward, the layers are bonded with an adhesive, the perlite layer is a perlite sound-absorbing board, the asbestos layer is an asbestos board, and the gypsum layer is a gypsum board. In this way, while playing a good fireproof role, it also has a sound-absorbing role and is beautiful as a whole.

[0004] but:

[0005] In the technical solution of the prior art, only the gypsum board has a sound insulation effect, but the sound insulation effect of the gypsum board is limited and cannot really achieve a soundproofing effect, and the sound insulation is still lacking. For this reason, we have made improvements to the prior art and proposed a fire door with good sound insulation effect. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the utility model provides a fireproof door with good sound insulation effect.

[0008] (II) Technical solution

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fire door with good sound insulation effect, comprising a fire door body, the front side of the fire door body is provided with a groove, and a fireproof glass is fixedly installed at the groove mouth, the fire door body comprises: an explosion-proof layer, a sound insulation layer, a sound receiving layer, and a flame retardant layer, the front side of the fire door body is fixedly connected with a front door handle, the back side of the fire door body is provided with a rear door handle, and a smoke sensor is fixedly installed on the fire door body.

[0010] Preferably, the explosion-proof layer is an explosion-proof plate.

[0011] Preferably, the sound insulation layer is a sound insulation felt, and the sound insulation layer can effectively isolate internal and external noises.

[0012] Preferably, the sound-absorbing layer is a fireproof sound-absorbing board. By opening a plurality of sound-absorbing holes on the fireproof sound-absorbing board, the sound insulated by the sound insulation felt can be effectively eliminated, and further sound insulation treatment is performed to achieve the purpose of double sound insulation.

[0013] Preferably, the flame retardant layer is a flame retardant sponge. By arranging the flame retardant sponge, since the flame retardant sponge is generally a fireproof material synthesized by adding flame retardants to various polyurethanes, the fireproof sponge adopts imported flame retardants, which can effectively reduce the burning time, delay combustion, and block smoke to cause the fire site to self-extinguish. The fireproof sponge has the excellent properties of heat preservation, heat insulation, sound absorption, shock absorption, and flame retardancy. Therefore, together with the sound insulation layer and the sound absorption layer, it has a triple sound insulation effect.

[0014] Preferably, an inner groove is provided on the back side of the fire door body, and a rear hand-sliding door is hinged at the inner groove by a hinge. The rear door handle is fixedly mounted on the rear hand-sliding door. By providing the rear hand-sliding door, some commonly used fire-fighting equipment, such as a dry powder fire extinguisher, etc., can be placed in the inner groove, and an ordinary lock can be provided on the rear door handle for easy opening and closing.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a fireproof door with good sound insulation effect, which has the following beneficial effects:

[0017] 1. This kind of fireproof door with good sound insulation effect can effectively isolate the noise inside and outside by setting the sound insulation layer. By opening a number of sound-absorbing holes on the fireproof sound-absorbing board, the sound after being isolated by the sound insulation felt can be effectively eliminated. Further sound elimination treatment is performed to achieve the purpose of double sound insulation. By setting the flame-retardant sponge, since the flame-retardant sponge is generally a fireproof material synthesized by adding flame retardants to various polyurethanes, the fireproof sponge adopts imported flame retardants, which effectively reduces the burning time, delays combustion, and blocks smoke to cause the fire site to self-extinguish. The fireproof sponge has the excellent characteristics of heat preservation, heat insulation, sound absorption, shock absorption, and flame retardancy. Therefore, it is combined with the sound insulation layer and the sound receiving layer to achieve a triple sound insulation effect.

[0018] 2. This kind of fire door with good sound insulation effect can place some commonly used fire-fighting equipment, such as dry powder fire extinguisher, in the inner groove by setting the rear hand sliding door, and set an ordinary lock on the rear door handle to facilitate opening and closing.
