As shown in fig. 1-4, the anti-slip layer structure for a guide rail beam 200 according to an embodiment of the present invention includes a polymer adhesive bottom layer 2 and a mixed layer 3.
Specifically, the polymer adhesive lower layer 2 is adapted to be disposed on the upper surface of the steel plate layer 201. Here, the polymer adhesive 32 in the "polymer adhesive bottom layer 2" and the "polymer adhesive 32" in the following can be understood as a kind of adhesive material mainly composed of a polymer compound, which is also called a polymer adhesive or a polymer binder, such as paste, glue, epoxy glue, and the like.

Moreover, the steel plate layer 201 can be completely sealed by the polymer adhesive bottom layer 2, so that a completely sealed sealing layer is formed, and the steel plate layer 1 is high in corrosion resistance.
The mixed layer 3 is arranged on the upper surface of the polymer adhesive bottom layer 2, the mixed layer 3 is formed by mixing crushed stones 31 and polymer adhesive 32, and a part of the crushed stones 31 in the mixed layer 3 protrudes out of the upper surface of the polymer adhesive 32. The broken stones 31 inside the polymer adhesive 32 are wrapped by the polymer adhesive 32, the polymer adhesive 32 is not fully filled between the broken stones 31 on the upper surface of the mixing layer 3, natural structural depth can be formed, the drainage effect is good, and the broken stones can generate large friction force with tires of rail vehicles such as rubber-tyred tramcars, such as rubber tires, so that the driving safety of the rail vehicles such as the rubber-tyred tramcars in rainy days is greatly improved. Moreover, the polymer adhesive 32 is not easily softened after being cured, so rutting does not occur in high-temperature weather, and no VOC (volatile organic compounds, which is an organic matter commanding emission in the ordinary sense, but is defined in the environmental protection sense to be an active volatile organic matter, i.e., a volatile organic matter which can cause harm) is emitted, thereby being safe and environment-friendly.
Compare with traditional cement concrete layer or bituminous concrete layer, according to the utility model discloses the skid resistant course structure has great tensile strength, and the elongation is higher than the elongation of steel, can not produce the crack during steel deck 201 elastic deformation. Moreover, the paving thickness of the polymer adhesive bottom layer 2 and the mixed layer 3 of the anti-skid layer structure is smaller than that of the steel plate layer 201, so that the clearance of the steel bridge is not obviously influenced. In addition, the sum of the weights of the polymer adhesive bottom layer 2 and the mixed layer 3 is only 1/10 of the traditional cement concrete layer or asphalt concrete layer, and the calculation of the rigidity of the guide rail beam 200 is not influenced. In addition, the antiskid layer structure takes about 4 hours from the beginning of construction to the opening of traffic, the construction time is short, the noise is small, and the operation line is convenient and fast to repair.
According to the utility model discloses an skid resistant course structure for guide rail roof beam 200, when the skid resistant course structure is applied to guide rail roof beam 200, through set up polymer gluing agent bottom 2 on the upper surface at steel deck 201, and set up the mixed layer 3 that is formed by mixing rubble 31 and polymer gluing agent 32 on the upper surface of polymer gluing agent bottom 2, and make the upper surface of partly protrusion polymer gluing agent 32 of rubble 31 in the mixed layer 3, can effectively guarantee adhesive force between polymer gluing agent bottom 2 and the steel deck 201, and rubble 31 surface can form great structure degree of depth, thereby be convenient for the drainage, and can produce great frictional force with rail vehicle for example the tire of rubber tyer tram, for example rubber tire, guarantee rainy day driving safety.
According to some embodiments of the utility model, in order to improve the bonding fastness between polymer adhesive bottom and the steel deck 201 still further, can be with the upper surface clean up of steel deck 201, for example, no greasy dirt, loose rust and dust etc. rust removal grade reaches Sa2.5, and surface cleanliness is 0 level, 1 level or 2 levels. Here, "sa 2.5" means that the surface is free from scale, oil stain, rust, etc., and is very thorough in spray or projectile rust removal, and any remaining marks are required to be colored spots or streaks.
Optionally, the thickness of the polymer adhesive bottom layer 2 is t1Wherein t is1Satisfies the following conditions: t is not less than 0.5mm1Less than or equal to 2 mm.

For example, when the thickness t is1When the thickness is less than 0.5mm, the thickness of the polymer adhesive bottom layer 2 is small, and a good anti-corrosion effect cannot be achieved; when the thickness t is1When the thickness is larger than 2mm, the thickness of the polymer adhesive bottom layer 2 is larger, more materials are used, and the cost is higher. Further optionally, t1Further satisfies the following conditions: t is t11 mm. For example, the cleaned upper surface of the steel plate layer 201 may be coated with a polymer adhesive bottom layer 2 with a thickness of 1mm, so as to completely seal the upper surface of the steel plate layer 201, and to play a role in corrosion prevention of the steel plate layer 201.

For example, the upper surface of steel plate layer 201 may be treated to have a rough surface 2011 with a certain roughness by shot blasting or sand blasting. By such an arrangement, the polymer adhesive bottom layer can be further firmly bonded with the steel plate layer 201.
