[0020] Reference Figures 1 to 3 , a plate for simulating ice and snow surface and a fixing method thereof, comprising a plate body 1 and a plurality of connecting members 2 for connecting the plate body;

[0021] In order to facilitate the use of the connecting piece, the four sides of the plate body are provided with contoured grooves 11 for fitting the connecting piece;

[0022] In order to improve the connection stability between the plate bodies 1 and ensure quick installation and prevent loosening during use after installation, the profiling grooves 11 are arranged in a trapezoidal structure, and the square grooves 11 between the plate bodies 1 directly correspond to the plate surface profiling grooves 11 arranged one-to-one with each other, and the side with a larger angle of the profiling groove is placed on the inner side of the plate, and the side with a smaller angle is arranged on the outer side of the plate;

[0023] The connector 2 is in an X-shaped structure and is installed in the corresponding profiling grooves 11 of the two adjacent plate bodies after being spliced. The dovetail groove design of the X-shaped structure of the connector can effectively exert a good tensile force in the lateral direction after being fixed because it has a large force-bearing surface, which can reduce the force on the screws and will not bend in the lateral direction only due to the force on the bolts. The bolts of the matching connector can effectively play the role of making each plate on the same surface in the longitudinal direction after the plates are fixed.

[0024] In order to effectively perform fixed installation, a fixing hole 12 is provided in the profiling groove 11 to cooperate with the connecting member 2 for fixing; the connecting member is provided with holes 21, which are respectively provided corresponding to the fixing holes 12 on the profiling groove 11, so as to facilitate fixing by screws and bolts;

[0025] There are two metal threaded rings in the two holes of the connector, which can be used to fix the plate with matching bolts;

[0026] The two sides of the connecting piece have the same structure and are axially symmetrical, so when fixing, it is not necessary to consider the front and back of the connecting piece, and it only needs to be embedded in the plate to facilitate the next step of fixing;

[0027] refer to Figure 3 , the installation method of this embodiment is: assemble the plate body side by side, and arrange the contoured groove parts one by one relative to each other to form the same shape as the connecting piece;

[0028] Then splice according to the area to be laid and connect according to the above requirements;

[0029] The connecting piece is embedded in the contoured groove where the plates are connected, and a connecting piece is placed on the two plate bodies at the same time, and then fixed on the plates by bolts and screws, and the height of the installed connecting piece does not exceed the surface of the plate body;

[0030] The outermost contoured groove does not need to be installed with connectors, thereby reducing installation time and improving efficiency.

[0031] The method for preparing the plate body comprises the following steps:

[0032] Material preparation, select appropriate preparation materials, and determine the required plate size according to needs;

[0033] Mixing of materials: 100 parts of ultra-high molecular weight polyethylene raw material, 10 parts of glass beads, 0.3 parts of UV resistance, 0.5 parts of coupling agent, 3 parts of polyethylene wax, and 1 part of zinc stearate are selected according to the mass ratio, and they are stirred and mixed together to prepare the material;

[0034] Processing and forming: processing the processed mixed materials, forming them into plate bodies and connecting parts according to the required size;

[0035] In this embodiment, the glass microbeads can enhance the hardness and rigidity of the surface, reduce the thermal shrinkage ratio, and the anti-UV can enhance the ability to resist ultraviolet rays outdoors to prevent it from aging and cracking. Polyethylene wax can enhance the self-lubricating property of the material, and the plate can still maintain a good friction coefficient after being rubbed by tires for a long time. Zinc stearate is used as a lubricant to enhance the lubricity of the material surface. The role of the coupling agent in the composite material is that it can react with certain groups on the surface of the reinforcing material and with the matrix resin to form an interface layer between the reinforcing material and the resin matrix. The interface layer can transfer stress, thereby enhancing the bonding strength between the reinforcing material and the resin, and improving the performance of the composite material. At the same time, it can also prevent other media from penetrating into the interface, improve the interface state, and be beneficial to the aging resistance, stress resistance and electrical insulation properties of the product;

[0036] The specific simulation implementation is that the workers lay the boards flat on the floor, and the boards are connected by connectors. The connector boards are fixed by bolts. Countersunk holes are provided at the bolt positions on the board surface. Under the premise of ensuring the connection and tightening, the flatness of the board surface is guaranteed. Expansion joints are left at the joints of the boards, which ensures the flatness of the board surface in places with large temperature differences and greatly improves its service life. It can be used after the splicing is completed. There is no need to sprinkle water to meet the simulation of ice and snow surfaces with adhesion coefficients of 0.1 and 0.3. The material itself has good self-lubricating properties. Without adding any additives, the friction coefficient can be controlled at about 0.1 to simulate the friction coefficient of the ice surface. By adding glass beads, the friction coefficient of the board is increased to 0.3 to simulate the friction coefficient of the snow surface.

[0037] The benefits of the present invention are that the technical solution conducts simulation tests through self-made boards, the density of the boards is close to the density of water, and through appearance size design, a new type of mortise and tenon structure is adopted for splicing; the weight of one board is only 30kg, and one worker can easily complete the installation and splicing; it not only reduces the labor intensity of the workers, but also improves the installation efficiency; the present invention can be quickly assembled, and is relatively convenient to use and disassemble; it can stably and firmly connect the boards, and will not fall off or be damaged easily.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
