[0007] Since the surface of the floor covering is smooth, it is convenient to move the trolley when transporting materials. After raining, the surface is wet and slippery, and the water-swelling adhesive tape protrudes to form a protrusion higher than the upper surface of the PVC base layer, thereby playing an anti-skid role.

[0008] Further provided, the groove is a U-shaped groove, and the water-swelling adhesive tape is bonded only with the arc-shaped part of the U-shaped groove, and the remaining part is in abutment.

[0009] In this way, only the water-swelling adhesive tape is bonded with the arc-shaped part of the U-shaped groove, and the remaining part is in abutment, so that the water-swelling adhesive tape has enough parts to swell and protrude to form a friction structure.

[0010] Further settings, the water-swelling adhesive strip includes a U-shaped part, a vertical part and a horizontal part, the vertical part has two, respectively with the two ends of the U-shaped part fixed, the horizontal part two ends are fixed with two vertical parts, the U-shaped part, vertical part and horizontal part form a cavity in the middle, the U-shaped part is bonded with the arc-shaped part of the U-shaped groove, and the outer surface of the horizontal part is flush with the upper surface of the PVC base layer.

[0011] The water-swelling adhesive strip is made into an internal hollow structure, which is beneficial to deformation of the water-swelling adhesive strip.

[0012] Further settings, a support part is arranged in the water-swelling adhesive strip, the support part is located between the two vertical parts, and the lower end of the support part is fixed with the U-shaped part, and the upper end is fixed with the lower end surface of the horizontal part.

[0013] The support part is arranged to reduce the amount of water-swelling adhesive strip swelling into the cavity, so that the structure of the water-swelling adhesive strip protruding from the upper surface of the PVC base layer is more, which is beneficial to anti-skid.

[0014] Further settings, the support part includes an upper support part and a lower support part, the upper support part is in the shape of an isosceles trapezoid in cross section, and the lower base of the trapezoid is fixed with the horizontal part, and the lower support part is in the shape of a V in cross section, and the sharp part of the V is fixed with the upper base of the trapezoid.

[0015] The V-shaped structure forms a triangular support structure with the arc-shaped part, which is stable and not easy to deform, and the isosceles trapezoid of the upper support part is also not easy to deform downward, so that the upper surface of the PVC base layer is forced to protrude outward to form an anti-skid structure.

[0016] Further settings, the setting interval of the two adjacent grooves is 5-6 times the width of the groove.

[0017] In this way, the amount of groove setting is reduced as much as possible, and the anti-skid requirement is met.

[0018] Further settings, the upper support part is arranged at intervals with the vertical part.

[0019] Further settings, the material of the support part is a rigid material.

[0026] The specific embodiments are only an explanation of the present application, which is not a limitation of the present application, and those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.

[0027] A floor covering includes a PVC base layer 1, the upper surface of the PVC base layer 1 is smooth and provided with a groove 11, the setting interval of adjacent two grooves 11 is 5-6 times the width of the groove 11. A water-swelling adhesive strip 2 is bonded in the groove 11, and the water-swelling adhesive strip 2 is flush with the upper surface of the PVC base layer 1 in the absence of water. Since the surface of the floor covering is smooth, it is convenient to move the cart when transporting materials; after the rain, the surface is wet and slippery, the water-swelling adhesive strip 2 protrudes to form a protrusion higher than the upper surface of the PVC base layer 1, thereby being able to play a role in preventing slipping.

[0028] The groove 11 is a U-shaped groove, and the water-swelling adhesive strip 2 is bonded only with the arc-shaped part 111 of the U-shaped groove, and the remaining part is abutted; specifically, the water-swelling adhesive strip 2 includes a U-shaped part 21, a vertical part 22 and a horizontal part 23, the vertical part 22 has two, which are respectively fixed with both ends of the U-shaped part 21, and the horizontal part 23 is respectively fixed with both ends of the two vertical parts 22. A cavity 24 is formed in the middle of the U-shaped part 21, the vertical part 22 and the horizontal part 23, the water-swelling adhesive strip 2 is made into a hollow structure, which is beneficial to the deformation of the water-swelling adhesive strip 2. The U-shaped part 21 is bonded with the arc-shaped part 111 of the U-shaped groove, and the outer surface of the horizontal part 23 is flush with the upper surface of the PVC base layer 1. In this way, only the water-swelling adhesive strip 2 is bonded with the arc-shaped part 111 of the U-shaped groove, and the remaining part is in the abutting mode, so that the water-swelling adhesive strip has enough parts to absorb water and protrude to form a friction structure.

[0029] A support part 3 is arranged in the water-swelling rubber strip 2, the material of the support part 3 is rigid material, specifically aluminum profile. The support part 3 is located in the middle of the two vertical parts 22, the lower end of the support part 3 is fixed with the U-shaped part 21, and the upper end is fixed with the lower end face of the horizontal part 23. Specifically, the support part 3 includes an upper support part 31 and a lower support part 32, the cross section of the upper support part 31 is isosceles trapezoid, and the lower base of the trapezoid is fixed with the horizontal part 23, so that the protruding amount of the horizontal part 23 can be limited to a certain extent. The two sides of the upper support part 31 are spaced apart from the vertical part 22. The cross section of the lower support part 32 is V-shaped, and the sharp part of the V-shaped part is fixed with the upper base of the trapezoid. The arrangement of the support part 3 reduces the amount of water-swelling rubber strip 2 swelling into the cavity 24, so that the structure of the water-swelling rubber strip 2 protruding on the upper surface of the PVC base layer 1 is more, which is beneficial to anti-skid. The V-shaped structure and the arc-shaped part 111 form a triangular support structure, the structure is stable and not easy to deform, and the isosceles trapezoid of the upper support part 31 is also not easy to deform downward, so that the PVC base layer 1 is forced to form an anti-skid structure on the upper surface.
