Light composite floor applied to train floor part

Technical Field

The utility model belongs to a light laminate flooring especially indicates the light laminate flooring who is applied to train floor position.

Background

The floor is an indispensable part for carrying the operation of people in the train on the train structure, and the product needs to have the service life of at least 30 years. Meanwhile, along with the more sophisticated production technology of the railway vehicles, the requirements on the weight, the environmental protection performance and the fireproof performance of the vehicle body parts are higher and higher.

The floor used on the existing high-speed rail and motor train unit is mainly a wood floor, and the floor used on the urban rail and the subway vehicle is mainly an aluminum honeycomb floor. The wooden floor is easily deformed under the influence of weather in the long-term use process, and subsequent overhaul and maintenance are more tedious and consume a large amount of manpower and material resources. The aluminum honeycomb floor uses a large amount of adhesives in the production and preparation process, the environmental protection performance of the product is poor, toxic and harmful gases are easily released when a fire disaster happens, and meanwhile, the overall weight of the material is large because the main structure body is made of metal aluminum, so that the weight reduction of a vehicle body is not facilitated.

Disclosure of Invention

The utility model provides a be applied to light laminate flooring at train floor position to solve the easy deformation of wooden floor that exists at present, aluminium honeycomb floor weight great, use adhesive, the poor problem of feature of environmental protection.

The utility model adopts the technical proposal that: the upper floor layer and the lower floor layer are parallel to each other, sandwich fillers are fixedly connected between the upper floor layer and the lower floor layer, and three-dimensional frameworks are arranged in the sandwich fillers.

The framework unit of the three-dimensional framework adopts an X shape or a needle shape.

When the framework units are in an X shape, each framework unit is perpendicular to the upper floor layer and the lower floor layer, the X-direction framework units and the Y-direction framework units are perpendicular to each other to form a unit group, and the unit groups are uniformly distributed between the upper floor layer and the lower floor layer.

The distance between the two parallel X-direction framework units is 2.1cm, and the distance between the two parallel Y-direction framework units is 2.0 cm.

When the skeleton units of the three-dimensional skeleton adopt the needle type, each skeleton unit is perpendicular to the upper floor layer and the lower floor layer and is uniformly distributed.

The floor upper layer, the sandwich filler and the floor lower layer form a single-layer structure, N layers of single-layer structures are fixedly connected with one another to form a multi-layer structure, and N is a natural number greater than 1.

And N is 2-5.

And N is 3.

The utility model has the advantages that the structure is novel, the upper and lower layers of the floor are prepared by resin curing, which is often called as glass fiber reinforced plastic (FRP or GFRP), the product has the advantages of wear resistance, deformation resistance and high structural strength, and the service life of the product can be effectively prolonged; the floor core material is composed of a floor sandwich filler and a three-dimensional framework structure in the floor, the floor sandwich filler has certain mechanical strength and high bending strength and compressive strength, and after the floor sandwich filler is combined with the three-dimensional framework structure, the overall mechanical performance of the structure is integrally further improved. The floor breaks through the structural strength of the traditional floor due to the transverse and longitudinal cross supporting form of the three-dimensional framework, has higher shear strength and rigidity, and simultaneously greatly avoids the condition that the surface of the floor collapses in the long-term use process due to the uniform filling of the filler in the core material. The low density of the floor sandwich filler also enables the overall density of the final floor structure to be far lower than that of a common floor in the market, the requirement for weight reduction of the whole train is high during design of the train, the floor is extremely large in using area on a train body, so that the local plate makes a prominent contribution to the overall weight reduction of the train, all materials related to the floor structure are environment-friendly and excellent in fireproof performance, the defects of poor environment protection and fireproof performance of the traditional floor material are overcome, and the floor sandwich filler has the characteristics of light weight, high structural strength, deformation resistance, environment friendliness and the like and excellent fireproof performance.
