Protective coatings are arranged on the outer surfaces of the top plate and the bottom plate. The utility model discloses simple structure, intensity height, durability are high.
Description
Technical Field
The utility model relates to a combined material field especially relates to a combined material sleeper.
Background
Sleepers are often used for carrying objects and are an indispensable material in the field of railway construction, laying of special track running equipment and carrying equipment. Although the existing wood sleeper is convenient to process, the service life of the existing wood sleeper is limited due to the difficulty in material selection, insufficient strength and durability, and the existing wood sleeper is easy to age. Although the concrete sleeper can solve the defects, the problems of poor elasticity and poor noise and shock absorption are also caused, and the concrete sleeper is large in mass and inconvenient to install and maintain.
SUMMERY OF THE UTILITY MODEL
In order to solve the above-mentioned defects, the present invention aims to provide a composite sleeper with simple structure, high strength and high durability, which is fixed by double-layer combination and groove connection.
In order to achieve the above object, the utility model discloses a following technical scheme realizes: the composite material sleeper is of a double-layer structure and comprises a top plate and a bottom plate, wherein the top plate and the bottom plate are both made of glass fiber reinforced polyurethane composite materials, the lower bottom surface of the top plate and the upper top surface of the bottom plate are respectively provided with a tenon and a mortise which are matched with each other, and the top plate and the bottom plate are fixedly connected through the mortise.
Further, protective coatings are arranged on the outer surfaces of the top plate and the bottom plate.
Furthermore, the thickness of the protective coating is 2.5-3.5mm, the protective coating comprises an upper coating and a lower coating, the upper coating is a putty material coating, and the lower coating is an anti-aging water-based coating.
Further, the glass fiber of the glass fiber reinforced polyurethane composite material is 9600tex glass fiber yarn.
Further, the top plate and the bottom plate are fixedly bonded through epoxy vinyl adhesive.
The utility model has the advantages that: the double-layer combination is adopted, the connection is carried out in a groove connection mode, epoxy vinyl adhesives are used for bonding between layers, and the obtained composite material sleeper is higher in strength and durability.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the composite sleeper has a double-layer structure, and comprises a top plate 1 and a bottom plate 2, wherein the top plate 1 and the bottom plate 2 are both made of glass fiber reinforced polyurethane composite materials, so that the composite sleeper has the advantage of good mechanical properties and is far higher than the mechanical strength of a wooden sleeper. And the used polyurethane composite material has higher durability, longer service life, lower maintenance cost and higher cost performance than a wooden sleeper. It has the advantages of light weight and high strength, and is superior to common cement concrete sleeper.
The lower bottom surface of the top plate 1 and the upper top surface of the bottom plate 2 are respectively provided with a tenon 3 and a mortise 4 which are matched with each other, and the top plate 1 and the bottom plate 2 are fixedly connected through the mortise. The top plate 1 and the bottom plate 2 are also fixed by bonding with epoxy vinyl adhesive. The outer surfaces of the top plate 1 and the bottom plate 2 are both provided with protective coatings 5. The thickness of the protective coating 5 is 2.5-3.5mm, the protective coating 5 comprises an upper layer coating and a lower layer coating, the upper layer coating is a putty material coating and has a good protective effect on the composite material sleeper; the lower layer coating is an anti-aging water-based coating, belongs to an environment-friendly coating and has good aging resistance. The glass fiber of the glass fiber reinforced polyurethane composite material is 9600tex glass fiber yarn.
The utility model discloses a bilayer structure, groove connect fixedly, use the ethylene-based binder of epoxy to bond between the layer. The groove mode between the two layers can provide a strong meshing effect, and the damage of relative displacement between the layers can be avoided. The adhesive used for the double-layer interfaces can well ensure the bonding strength between the interfaces, so that the interfaces are firmly connected, and the composite material sleeper with high strength and high durability is obtained.
Claims (5)
