Description

Technical Field

[0001] This utility model relates to an outdoor flooring, and more particularly to a corrosion-resistant composite flooring for outdoor use. Background Technology

[0002] Outdoor flooring is constantly exposed to rain, humidity, ultraviolet radiation, and temperature fluctuations. Ordinary wood is prone to absorbing water, swelling, and rotting in humid environments, shortening its lifespan. To cope with the harsh outdoor environment, existing outdoor flooring undergoes anti-corrosion treatment.

[0003] Existing technologies for preventing corrosion in flooring include: 1. High-temperature pyrolysis or modification treatment to reduce the moisture absorption of wood, thereby reducing moisture absorption deformation and the growth of decay fungi, giving it higher weather resistance and extending its service life. However, the treatment cost is high, and the surface requires regular maintenance after long-term use, which is troublesome. 2. Using agents such as CCA and ACQ for corrosion and termite prevention, preserving the natural texture of the wood. However, some agents contain harmful substances such as chromium and arsenic, resulting in a low environmental protection coefficient. 3. Using wood-plastic composite flooring. Wood-plastic composite flooring is made of a mixture of plastic and wood fibers. It has the advantages of being waterproof, mildew-proof, acid and alkali resistant, and having low maintenance costs. However, it is easily deformed by thermal expansion and contraction and has low load-bearing capacity.

[0004] Therefore, existing outdoor corrosion-resistant flooring suffers from problems such as high processing costs, insufficient environmental friendliness, easy deformation, and low load-bearing capacity. Utility Model Content

[0005] The purpose of this invention is to provide an outdoor corrosion-resistant composite flooring. This invention is characterized by being environmentally friendly, resistant to deformation, and having high load-bearing capacity.

[0006] The technical solution of this utility model is: outdoor corrosion-resistant composite flooring, including a load-bearing layer, a wood-plastic composite substrate on the surface of the load-bearing layer, a grid frame inside the wood-plastic composite substrate, carbon fiber filling the grid holes of the grid frame, an edge banding strip on the periphery of the wood-plastic composite substrate, an elastic strip on the outer side of the edge banding strip, a micro-foamed layer on the surface of the wood-plastic composite substrate, and a wear-resistant layer on the surface of the micro-foamed layer.

[0007] In the aforementioned outdoor corrosion-resistant composite flooring, the elastic strip has a cavity inside.

[0008] In the aforementioned outdoor corrosion-resistant composite flooring, the edge banding is U-shaped, with its top surface embedded in the micro-foamed layer and its bottom surface embedded in the load-bearing layer.

[0009] In the aforementioned outdoor corrosion-resistant composite flooring, the load-bearing layer includes a first load-bearing frame and a second load-bearing frame distributed vertically. Several buffer strips are provided between the first load-bearing frame and the second load-bearing frame. A waterproof and sound-insulating layer is provided at the bottom of the second load-bearing frame, and several drainage grooves are provided at the bottom of the waterproof and sound-insulating layer.

[0010] In the aforementioned outdoor corrosion-resistant composite flooring, both sides of the buffer strip are provided with reinforcing ribs that are respectively connected to the first load-bearing frame and the second load-bearing frame. The reinforcing ribs are triangular in shape, and the two reinforcing ribs form a centrally symmetrical structure with the buffer strip as the center.

[0011] In the aforementioned outdoor corrosion-resistant composite flooring, the wear-resistant layer is a UV coating or a polymer film layer.

[0012] In the aforementioned outdoor corrosion-resistant composite flooring, the cross-section of the grid frame is wavy or arc-shaped, extending downwards from the middle to both sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The load-bearing layer of this invention is used to improve the load-bearing capacity of the floor. A carbon fiber mesh frame is set inside the wood-plastic composite substrate to improve the strength, deformation resistance and compressive strength of the wood-plastic composite substrate and prevent it from breaking. Edge strips are set on the sides of the wood-plastic composite substrate to protect the edges and corners of the substrate and make them less prone to wear. Elastic strips are used to absorb expansion stress to prevent warping or cracking caused by the widening of gaps, reduce gaps caused by floor deformation, reduce floor corrosion, and improve the floor's sound insulation effect.

[0015] Furthermore, the wood-plastic composite substrate combined with the micro-foamed layer has flame-retardant, waterproof, and mildew-proof properties. The materials used are relatively environmentally friendly, and no additional anti-corrosion treatment is required to achieve a high corrosion resistance effect, reducing processing costs. Moreover, the micro-foamed layer combined with the wear-resistant layer on the floor surface can also play a role in anti-slip, cushioning, corrosion resistance, and wear resistance, improving the impact resistance and safety of outdoor flooring and extending its service life.

[0016] Therefore, this utility model has the characteristics of being environmentally friendly, not easily deformed, and having high load-bearing capacity. Attached Figure Description

[0022] Example:

[0023] like Figures 1-2 As shown, the outdoor corrosion-resistant composite flooring includes a load-bearing layer 1, a wood-plastic composite substrate 2 on the surface of the load-bearing layer 1, a grid frame 21 inside the wood-plastic composite substrate 2, carbon fiber 22 filling the grid holes of the grid frame 21, an edge banding strip 23 on the periphery of the wood-plastic composite substrate 2, an elastic strip 24 on the outer side of the edge banding strip 23, a micro-foamed layer 3 on the surface of the wood-plastic composite substrate 2, and a wear-resistant layer 4 on the surface of the micro-foamed layer 3.

[0024] The load-bearing layer 1 of this invention is used to improve the load-bearing capacity of the floor. A grid frame 21 filled with carbon fiber 22 is set inside the wood-plastic composite substrate 2 to improve the strength, deformation resistance and compressive strength of the wood-plastic composite substrate 2 and prevent it from breaking. An edge strip 23 is set on the side of the wood-plastic composite substrate 2 to protect the edges and corners of the wood-plastic composite substrate 2 and make it less prone to wear. An elastic strip 24 is used to absorb expansion stress to prevent warping or cracking caused by the expansion of gaps. It reduces the gaps generated when the floor deforms, makes the installation between the floorboards more tight, prevents water penetration, blocks the path of insects and ants, reduces the corrosion of the floor, reduces the sound and vibration transmission of the floor, and improves the sound insulation effect of the floor.

[0025] Furthermore, the wood-plastic composite substrate 2, combined with the micro-foamed layer 3, has flame-retardant, waterproof, and mildew-proof properties. The materials used are relatively environmentally friendly, and no additional anti-corrosion treatment is required to achieve a high corrosion resistance effect, reducing processing costs. Moreover, the micro-foamed layer 3, combined with the wear-resistant layer 4, placed on the floor surface, can also play a role in anti-slip, cushioning, corrosion resistance, and wear resistance, protecting the internal structure of the floor, improving the impact resistance and safety of outdoor flooring, and extending its service life.

[0026] The elastic strip 24 has a cavity 25 inside. The cavity 25 can increase the deformation space of the elastic strip 24, thereby strengthening the deformation capacity of the elastic strip 24 and reducing installation gaps.

[0027] The edge banding strip 23 is U-shaped. Its top surface is embedded in the micro-foamed layer 3, and its bottom surface is embedded in the load-bearing layer 1. Both the micro-foamed layer 3 and the load-bearing layer 1 have grooves for the edge banding strip 23 to be inserted. The U-shaped design of the edge banding strip 23 protects the wood-plastic composite substrate 2 and enhances the connection strength between the wood-plastic composite substrate 2 and the micro-foamed layer 3 and load-bearing layer 1, thereby improving the overall structural strength and stability of the flooring.

[0028] The load-bearing layer 1 includes a first load-bearing frame 11 and a second load-bearing frame 12 distributed vertically. Several buffer strips 13 are provided between the first load-bearing frame 11 and the second load-bearing frame 12. A waterproof and sound-insulating layer 14 is provided at the bottom of the second load-bearing frame 12, and several drainage grooves 15 are provided at the bottom of the waterproof and sound-insulating layer 14. The first load-bearing frame 11 and the second load-bearing frame 12 adopt a double-layer structure. Combined with the buffer strips 13 in the middle, pressure buffering is provided to improve the load-bearing capacity of the floor. Combined with the bottom waterproof and sound-insulating layer 14, this improves the waterproof and moisture-proof capabilities of the floor and reduces noise.

[0029] The buffer strip 13 has reinforcing ribs 16 on both sides, which are respectively connected to the first load-bearing frame 11 and the second load-bearing frame 12. The reinforcing ribs 16 are triangular in shape, and the two reinforcing ribs 16 form a centrally symmetrical structure with the buffer strip 13 as the center. The reinforcing ribs 16 improve the dimensional stability and structural strength of the load-bearing layer 1 and prevent deformation and displacement under long-term pressure.

[0030] The wear-resistant layer 4 is made of UV coating or polymer film. UV coating or polymer film can improve the wear resistance, scratch resistance and stain resistance of the floor, inhibit the growth of bacteria and extend the service life of the floor.

[0031] The cross-section of the grid frame 21 is wavy or arc-shaped, extending downwards from the middle to both sides. The irregular cross-section of the grid frame 21 can disperse stress and improve load-bearing capacity.

[0032] The parts of this utility model not described in detail are existing technologies and therefore will not be specifically described here.
