The fireproof structure of the partition wall door of the cab, disclosed in China patent 201620986677.1, comprises an aluminum plate and an aluminum honeycomb, wherein a heat insulation material is adhered to the aluminum honeycomb, a stainless steel fireproof plate is adhered to the heat insulation material, an aluminum profile framework is adopted for the partition wall door and a door frame framework, fireproof expansion adhesive tapes are arranged at joints of the partition wall door and the door frame framework, the thickness of the heat insulation material is 10-20mm, the thickness of the stainless steel fireproof plate is 0.8-1.2mm, and the thickness of the fireproof expansion adhesive tapes is 3-6mm. The Chinese patent 202211149368.5 discloses a fireproof partition wall, which comprises a partition wall main body framework, wherein an inner side wall of the partition wall main body framework is provided with an inner side fireproof structure, an outer side wall of the partition wall main body framework is provided with an outer side fireproof structure, and the inner side fireproof structure and the outer side fireproof structure are used for inner and outer double-sided fireproof of the partition wall main body framework; the outside fireproof structure includes first ceramic fiber layer, first fire prevention phenolic aldehyde sheet layer and first steel sheet layer, the lateral wall of dividing wall main part framework sets gradually first ceramic fiber layer first fire prevention phenolic aldehyde sheet layer with first steel sheet layer. The Chinese patent 202021793596.2 discloses a partition fireproof partition of a railway vehicle cab, which comprises a partition main body plate, a partition main body plate and a partition main body plate, wherein the partition main body plate is a honeycomb plate; the connecting extension rib is arranged on one side of the dividing wall main body plate and used for connecting a cab; the fireproof expansion adhesive tape is arranged between the partition wall main body plate and the cab, and can expand and fill the gap between the connecting and extending rib and the cab. The sound insulation test is carried out on the aluminum honeycomb panel with the thickness of 12mm, and the result shows that the sound insulation quantity is about 23dB and cannot meet the specified 25dB requirement. Therefore, the partition wall with the sound insulation function meeting the technical requirements is developed and designed, and has positive economic and social values.
The utility model comprises the following steps:
the utility model aims to overcome the defects of the prior art, develop and design a partition wall with a sound insulation function, and realize the purpose of meeting the sound insulation requirement by additionally arranging a shed cloth layer.
In order to achieve the above object, the main structure of the partition wall with sound insulation function according to the present utility model comprises a partition wall body, a partition wall door and an armrest arranged on the front surface of the partition wall body, and a door lock arranged on the side surface of the partition wall body, wherein the partition wall body is connected with the partition wall door in a hinge manner, and the partition wall body is connected with the armrest in a bolt manner; the aluminum honeycomb composite board used for the partition wall body and the partition wall door has a sound insulation function, and the main body structure of the aluminum honeycomb composite board comprises a shed cloth layer, aluminum honeycomb layers arranged on two sides of the shed cloth layer and aluminum plate layers coated with the aluminum honeycomb layers.
Compared with the prior art, the utility model has the advantages that a layer of windshield shed cloth is added on the basis of the three-layer aluminum honeycomb plate structure of aluminum plate, aluminum honeycomb and aluminum plate, and the structure is changed into a five-layer structure, so that the sound insulation performance is improved, the toughness is enhanced, and the shock resistance is improved; the structure is simple, the thickness is unchanged,
