Technical Field

[0001] The utility model relates to the field of floor and stair tread design, in particular to an SPC anti-skid and wear-resistant stair tread. Background Art

[0002] SPC interlocking flooring consists of a thickened wear-resistant layer, a UV layer, a color film texture layer, and a base material layer. The base material is a composite board made by mixing stone powder and thermoplastic polymer materials and then extruding them at high temperature. It combines the properties and characteristics of wood and plastic to ensure the strength and toughness of the floor.

[0003] The prior art (Announcement No.: CN 214220332 U, Announcement Date: 2021.09.17) discloses a silent SPC floor structure for stairs, which consists of a gear transmission mechanism composed of a first gear and a second gear, pulling the fourth support plate to move outward, driving the second gear to rotate, and then driving the first gear to rotate, so that the first SPC floor moves upward, so that the first SPC floor and the second SPC floor can become a straight line, thereby achieving the purpose of facilitating the cleaning of garbage at the corner of the floor and the wall.

[0004] In the above solution, although the SPC floor can be made into a straight line to facilitate cleaning of the corner positions, it requires the installation of complex structures such as gears and hinges, which has high preparation costs. In addition, the transmission structure is prone to dirt and grime, and these positions are also inconvenient to clean. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0006] SPC anti-slip and wear-resistant stair slabs include several floor panels and several stair treads, wherein several of the floor panels are laid and installed on the ground, and several of the stair treads are laid and installed on the stairs;

[0007] The left edges of the floor and the stair treads are both formed with a male tenon, the left edge of the stair treads is detachably mounted with a positioning edge, and the right edge and positioning edge of the floor are both formed with a female tenon, and the male tenon and the female tenon are mutually engaged and assembled;

[0008] The positioning edge is fixedly installed on the stairs, and an arc-shaped edge is formed at the right edge of the stair tread. A semicircular transverse groove is formed on the inner side of the arc-shaped edge in a one-to-one correspondence with the stairs, and an anti-dropping insert is installed between the inner side of the arc-shaped edge and the semicircular transverse groove.

[0009] Furthermore: one end of the anti-dropout cannula is formed with a pull-in and pull-out handle.

[0010] Furthermore: a T-shaped structure is formed between the anti-dropout cannula and the insertion and extraction handle.

[0011] Furthermore, the floor and stair treads both include a UV film, a wear-resistant layer, a wood grain printing layer, a stone crystal core board layer and an EVA foam layer stacked from top to bottom.

[0012] Furthermore: the male tenon and the female tenon are integrally formed and arranged on the left and right sides of the stone crystal core board layer, and the left side and the curved edge of the stair tread are integrally formed and arranged on the left and right sides of the stone crystal core board layer.

[0013] Furthermore: a waterproof strip is installed between the male tenon and the female tenon.

[0014] Furthermore: the anti-dropout cannula is a hollow tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. When using it on stairs, first set a semicircular groove on the stairs, place the stair treads on the stairs, and the curved edge of the stair treads will form a circular hole structure with the semicircular groove. Then, insert the anti-dropping plug into the circular hole formed by the curved edge and the semicircular groove by plugging, thereby preventing the stair treads from rising and falling off by themselves, and making them more secure after installation.

[0017] 2. When removing the stair treads, you need to pull out the anti-dropping plug first. Then you can tilt the stair treads upwards, and then quickly remove them. It is convenient to clean the dirt between the stair treads and the positioning edges.

[0018] 3. When used on the ground, the floor uses a traditional inverted tenon structure to achieve quick assembly and easy use. When cleaning is needed, the two adjacent floors can be separated from each other by tilting them upwards, making it easier to clean the dirt between the two floors.
