Description

Technical Field

[0001] This utility model relates to the field of PVC micro-foamed co-extruded flooring technology, specifically a PVC micro-foamed co-extruded outdoor flooring. Background Technology

[0002] Traditional outdoor flooring materials such as wood and stone are susceptible to moisture, deformation, and corrosion, and have high maintenance costs. PVC flooring, as a new type of floor covering material, has advantages such as waterproofing, moisture resistance, and easy cleaning. However, traditional PVC flooring still suffers from insufficient wear resistance and poor slip resistance when used outdoors. Therefore, technicians in this field have developed PVC micro-foamed co-extruded outdoor flooring, which effectively improves the wear resistance of the flooring while ensuring a certain level of strength, greatly extending its service life. However, traditional outdoor flooring has vertical right-angle edges on both sides, requiring flooring fasteners to fix the flooring to the joist frame during installation. The gaps at the joints between floorboards are relatively large, allowing rainwater to easily seep into the joist frame and corrode it. The large gaps at the joints also affect the overall aesthetics of the installed flooring. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] The technical problem this invention aims to solve is that traditional outdoor flooring has two vertical right-angled sides. During installation, flooring clips are needed to fix the flooring to the joist frame. However, the gaps at the joints between the two floorboards are relatively large, allowing rainwater to easily seep into the joist frame and corrode it. Furthermore, the large gaps at the joints also affect the overall aesthetics of the installed flooring.

[0005] (II) Technical Solution

[0006] To solve the above problems, this utility model provides the following technical solution:

[0007] A PVC micro-foamed co-extruded outdoor flooring includes a micro-foamed body. The micro-foamed body has a male connecting end, a female connecting end, a first hollow groove, and a second hollow groove. The female connecting end includes a female end protrusion, a female end groove, and a female end groove. The male connecting end includes a male end groove, a male end protrusion, and a male end protrusion. The protruding surface of the female end protrusion faces the lower end surface of the micro-foamed body and mates with the male end groove. The female end groove is ridge-shaped, and the highest point of the female end groove is higher than the highest point of the female end groove. The female end groove mates with the male end protrusion, and the female end groove mates with the male end protrusion. The first hollow groove is located on the upper part of the second hollow groove, and there are multiple first and second hollow grooves, which are evenly distributed on the micro-foamed body.

[0008] Furthermore, both the male and female ends of the connector are provided with a fastener connection groove for connecting with the floor fastener.

[0009] Furthermore, a connecting edge is provided on the lower side of both the male and female connecting ends, and a serrated groove for connecting with the floor fastener is provided on both the upper and lower surfaces of the connecting edge.

[0010] Furthermore, the lower end face of the connecting male end is also provided with the serrated groove for connection with the floor fastener.

[0011] Furthermore, the lower end face of the connecting wooden point is also provided with the serrated groove that connects to the floor fastener.

[0012] Furthermore, the height H of the female end protrusion on the female end of the connector is not less than one-third of the thickness of the microfoam body.

[0013] Furthermore, the outer layer of the micro-foamed body is also provided with an ASA co-extrusion layer by co-extrusion, which is co-extruded onto the micro-foamed body by a co-extruder through a die.

[0014] Furthermore, the outer surface of the ASA co-extruded layer is provided with an anti-slip pattern.

[0015] (III) Beneficial Effects

[0016] The beneficial effects of this utility model are:

[0017] 1: The female and male connectors are plugged into each other, with very little gap between them. There is no gap in the foundation, which improves the aesthetics and effectively prevents rainwater from flowing onto the installation joists.

[0018] 2: The design of the hollowed-out groove one and hollowed-out groove two can not only reduce the weight of the entire outdoor floor, but also allow for the passage of outdoor power cords or other signal cables, so that the power cords or signal cables are not exposed to the outside, thereby increasing the service life of the power cords and signal cables and improving safety.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Please see Figures 1-5 The illustration shows a type of PVC microfoam co-extruded outdoor flooring, comprising a microfoam body 1. To enable interlocking connections between floorboards, a male connector 4 and a female connector 3 are provided on the microfoam body 1. Additionally, to reduce the overall weight of the flooring, two perforated grooves 5 and 6 are provided.

[0030] The female end 3 includes a female end protrusion 301, a female end groove 1 302 and a female end groove 2 303;

[0031] The male end 4 includes a male end groove 401, a male end protrusion 1 402, and a male end protrusion 2 403;

[0032] The protruding surface of the female end protrusion 301 faces the lower end surface of the micro-foamed body 1 and cooperates with the male end groove 401. The outer edge surface of the female end protrusion 301 abuts against the outer edge surface of the male end groove 401, forming a relatively sealed structure to prevent rainwater leakage.

[0033] To further enhance the water-proofing capability, the female end groove 302 is designed with a ridge-like structure, and the highest point of the female end groove 302 is higher than the highest point of the female end groove 303. The female end groove 302 is matched with the male end protrusion 402, and the female end groove 303 is matched with the male end protrusion 403.

[0034] The outer surface of the female end groove 302 abuts against the outer surface of the male end protrusion 402, and the outer surface of the female end groove 303 abuts against the outer surface of the male end protrusion 403. This curved gap has better water-proofing ability compared to the traditional vertical gap. Moreover, after the two floorboards are connected, the gap at the joint is small, resulting in a good overall aesthetic appearance.

[0035] The first perforated groove 5 is located on the upper part of the second perforated groove 6, and multiple first perforated grooves 5 and second perforated grooves 6 are provided and evenly distributed on the micro-foamed body 1. The first perforated groove 5 and the second perforated groove 6 can be designed to be the same or different shapes. In practical applications, this not only reduces the weight of the entire flooring and saves raw materials in production, but also allows outdoor power cords, signal cables, and other wires to be threaded through the first perforated groove 5 or the second perforated groove 6. In this way, the PVC micro-foamed body layer 1 can protect these wires from sun exposure, rain, and even physical damage from external factors, providing excellent protection.

[0036] Specifically, both the male end 4 and the female end 3 are provided with a fastener connection groove 7 for connecting with the floor fastener.

[0037] In this implementation scheme, the designed connecting groove 5 is used to fix the floor to the keel frame in conjunction with the use of floor fasteners.

[0038] Specifically, a connecting edge 8 is provided on the lower side of both the male end 4 and the female end 3, and the upper and lower surfaces of the connecting edge 8 are provided with serrated grooves 9 for connecting with the floor fastener. The lower end surface of the male end 4 is also provided with serrated grooves 9 for connecting with the floor fastener. The lower end surface of the connecting wooden point is also provided with serrated grooves 9 for connecting with the floor fastener.

[0039] In this implementation scheme, the serrated groove 9 is designed to increase the connection force between the floor and the floor fastener.

[0040] Specifically, the height H of the female end protrusion 301 on the female end 3 is not less than one-third of the thickness of the micro-foam body.

[0041] In this embodiment, ensuring a certain thickness for the height of the female end protrusion 301 is to ensure that the female end protrusion 301 has a certain strength, so that it is not easy to deform or break during transportation and installation.

[0042] Specifically, the outer layer of the microfoamed body 1 is also provided with an ASA co-extruded layer 2 by co-extrusion. The ASA co-extruded layer 2 is co-extruded onto the microfoamed body 1 by a co-extruder through a die. The outer surface of the ASA co-extruded layer 2 is provided with an anti-slip pattern.

[0043] In this implementation scheme, the ASA co-extruded layer 2 is designed to protect the PVC micro-foamed body layer 1 on the one hand, and to improve the anti-slip properties and aesthetics of the entire floor through the design of the anti-slip pattern.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
