Description

Technical Field

[0001] This utility model relates to the field of flooring technology, specifically to a high-strength aluminum-plastic composite floor. Background Technology

[0002] Aluminum-plastic composite (APC) flooring is a type of floor covering material that combines an aluminum alloy substrate with a polymer plastic panel, suitable for commercial, residential, and outdoor applications. Traditional outdoor APC flooring is susceptible to environmental and aging-related issues. Due to insufficient bonding strength between the aluminum alloy substrate and the polymer plastic panel, long-term use often leads to delamination between the two materials, causing damage and shortening its lifespan. Therefore, to improve the bonding strength of APC flooring and prevent delamination, we offer a high-strength APC flooring solution. Utility Model Content

[0003] The purpose of this invention is to provide a high-strength aluminum-plastic composite flooring that solves the problem of traditional outdoor aluminum-plastic composite flooring being easily peeled off due to insufficient bonding strength between the aluminum alloy substrate and the polymer plastic panel, which is affected by environmental factors and usage time.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-strength aluminum-plastic composite floor, comprising an aluminum alloy substrate and a plastic panel layer, wherein the aluminum alloy substrate and the plastic panel layer are interlocked and connected to each other;

[0005] The top surface of the aluminum alloy substrate is provided with a toothed structure. The top of the aluminum alloy substrate is provided with dovetail-shaped fastening grooves that are evenly spaced along the width direction of the aluminum alloy substrate. The middle of the aluminum alloy substrate is provided with a support plate connecting the fastening grooves and the bottom edge. The side of the aluminum alloy substrate is provided with a covering surface, a fitting groove, and a shrinking surface. The covering surface and the shrinking surface are connected by the fitting groove. The inner wall of the fitting groove is provided with an anti-detachment groove. The covering surface is located on the upper part of the side of the aluminum alloy substrate. The shrinking surface shrinks inward and is located on the lower part of the side of the aluminum alloy substrate. The side of the aluminum alloy substrate has a horizontally extending fastening rib at the bottom of the shrinking surface.

[0006] The side of the plastic panel layer is provided with a covering claw. The claw covers the covering surface and extends into the fitting groove to engage and connect. The inner side of the claw is provided with an anti-detachment protrusion that complements the anti-detachment groove. The top surface of the plastic panel layer is provided with a second tooth structure that matches the tooth structure. The top of the plastic panel layer is provided with a dovetail-shaped panel buckle that engages and connects with the buckle groove. The claws between adjacent spliced ​​plastic panel layers abut against each other.

[0007] Preferably, a thickened structure is provided at the corner where the top surface of the plastic panel layer meets the top of the claw.

[0008] Preferably, the top of the thickened structure on one side of the plastic panel layer is provided with a connecting part that splices with the top of the side of the adjacent plastic panel layer.

[0009] Preferably, the fastening ribs adjacent to the aluminum alloy substrate side are fixed by snap fasteners connected to the keel frame.

[0010] This utility model has the following beneficial effects:

[0011] The plastic panel layer is connected to the aluminum alloy substrate through multiple fastening points, including claws, anti-detachment protrusions, toothed structure II, and panel buckles. The claws cover both sides of the aluminum alloy substrate, and after splicing, the claws of adjacent aluminum-plastic composite flooring layers squeeze each other, making it difficult for the plastic panel layer to peel off. The support plate of the aluminum alloy substrate supports the connection groove, making the aluminum alloy substrate structurally strong and less prone to deformation when combined with the plastic panel layer. The plastic panel layer achieves stable edge bonding through the covering claws and anti-detachment protrusions. The aluminum alloy substrate increases the contact area with the claws through the covering surface, and the anti-detachment grooves and anti-detachment protrusions ensure stable edge bonding. The plastic panel layer achieves stable top bonding through the complementary connection of toothed structure II, panel buckles, and toothed structure I of the aluminum alloy substrate, greatly improving the overall strength of the aluminum-plastic composite flooring.

[0018] like Figure 1-4 As shown, this utility model provides a technical solution: a high-strength aluminum-plastic composite floor, comprising an aluminum alloy substrate 1 and a plastic panel layer 2, wherein the aluminum alloy substrate 1 and the plastic panel layer 2 are interlocked and connected to each other;

[0019] The top surface of the aluminum alloy substrate 1 is provided with a toothed structure 11. The top of the aluminum alloy substrate 1 is provided with dovetail-shaped fastening grooves 12 that are evenly spaced along the width direction of the aluminum alloy substrate 1. The middle of the aluminum alloy substrate 1 is provided with a support plate 13 that connects the fastening grooves 12 and the bottom edge.

[0020] The plastic panel layer 2 has a wrap-around claw 21 on its side. A thickened structure 211 is provided at the corner where the top surface of the plastic panel layer 2 meets the top of the claw 21.

The top of the thickened structure 211 on one side of the plastic panel layer 2 has a connecting part 212 that splices with the top of the side of the adjacent plastic panel layer 2. The connecting part 212 makes the splicing gaps of the aluminum-plastic composite flooring smaller and less prone to dust accumulation. The claw 21 wraps around the wrap-around... The surface 14 forms a right-angle corner extending into the fitting groove 15 for snap-fit ​​connection. The inner side of the claw 21 is provided with an anti-detachment protrusion 22 that complements the anti-detachment groove 18.
