Description

Technical Field

[0001] The utility model relates to the technical field of floors, in particular to a shock-absorbing SPC floor. Background Art

[0002] SPC flooring consists of a wear-resistant layer, a UV coating, a color film texture layer, and a base material layer. The wear-resistant layer is typically made of transparent PVC, which offers strong adhesion, abrasion resistance, and scratch resistance. The UV coating is formed by curing UV paint to prevent UV rays from evaporating the chemical substances within the board. The color film layer offers a variety of decorative patterns, including wood, stone, and carpet, to suit different occasions and tastes. The base material layer is a composite material made by mixing stone powder and thermoplastic polymer materials and then extruding them at high temperatures. It combines the properties and characteristics of both wood and plastic, resulting in excellent strength and toughness.

[0003] The above-mentioned SPC floor includes an SPC main body, which includes a base material layer and a color film texture layer, a wear-resistant layer and a UV layer sequentially arranged on the base material layer. A first locking part is provided at one end of the SPC main body, and a second locking part is provided at the other end of the SPC main body. The thickness of the first locking part and the second locking part are both less than the thickness of the SPC floor. A coupling groove is provided on the upper surface of the first locking part, and a tenon is provided on the lower surface of the second locking part.

[0004] For the above-mentioned SPC floor, usually, the base material layer is in direct contact with the ground during installation. Since the base material layer is made of stone powder and thermoplastic polymer material through high-temperature extrusion, its hardness is relatively high. Therefore, the force generated by the user walking on the floor cannot obtain energy absorption, thus causing greater vibration.

[0005] In addition, the flatness of the substrate layer is generally better, while the flatness of the ground is generally not as good as the flatness of the substrate layer. After the SPC floor is installed on the ground, there will be a small gap between the SPC floor and the ground. When the user walks on the SPC floor, the gap will cause the SPC floor to be unevenly stressed, resulting in the service life of the SPC floor failing to meet expectations. Utility Model Content

[0006] The utility model provides a shock-absorbing SPC floor. When the SPC floor is subjected to force, the SPC floor absorbs the vibration, thereby reducing the vibration.

[0007] The technical solutions to the above technical problems are as follows:

[0008] The shock-absorbing SPC floor comprises an SPC body, the SPC body comprising a base material layer, a color film texture layer, a wear-resistant layer, and a UV layer. The upper surface of the base material layer is fixed to one end of the color film texture layer, the other end of the color film texture layer is fixed to the wear-resistant layer, and the UV layer is disposed on the wear-resistant layer. A first locking portion is provided at one end of the SPC body, and a second locking portion is provided at the other end of the SPC body. The lower end of the first locking portion extends below the lower surface of the base material layer, forming an assembly space between the lower surface of the base material layer and the lower surface of the first locking portion.

[0009] The utility model also comprises a shock-absorbing pad, which is located in the assembly space and is fixed to the base material layer.

[0010] Furthermore, the lower surface of the substrate layer is provided with multiple rows of block components, two adjacent rows of block components have first inlay grooves arranged along the longitudinal direction of the substrate layer, each row of block components includes multiple protrusions, and a second inlay groove arranged along the transverse direction of the substrate layer is provided between two adjacent protrusions;

[0011] The upper surface of the shock-absorbing pad is provided with a first clamping strip arranged longitudinally along the shock-absorbing pad, and the upper surface of the shock-absorbing pad is also provided with a second clamping strip arranged transversely along the shock-absorbing pad, and the first clamping strip and the second clamping strip intersect vertically and horizontally to form a clamping groove.

[0012] When the shock-absorbing pad is combined with the base material layer, the first clamping strip is matched with the first inlay groove, the second clamping strip is matched with the second inlay groove, and the clamping groove is matched with the protrusion.

[0013] Furthermore, the first clip strip and the second clip strip are made of foamed polyurethane.

[0014] Furthermore, the material of the shock-absorbing pad is rubber.

[0015] In the present invention, when a force acts on the shock-absorbing SPC floor, the shock-absorbing pad will be subjected to the force first, thereby absorbing the generated vibration and reducing the vibration. The shock-absorbing pad will be compressed after being subjected to the force, and the size of the shock-absorbing pad in the lateral direction is much larger than the size of the first locking part. Therefore, after the shock-absorbing pad is compressed, the first locking part will quickly fit into the ground, so that the shock-absorbing SPC floor is subjected to uniform force.

[0030] like Figures 1 to 7 As shown, the shock-absorbing SPC floor of the present invention includes an SPC main body A and a shock-absorbing pad 8. The SPC main body A includes a base material layer 1, a color film texture layer 2, a wear-resistant layer 3, and a UV layer 4. The upper surface of the base material layer 1 is fixed to one end of the color film texture layer 2, and the other end of the color film texture layer 2 is fixed to the wear-resistant layer 3. The UV layer 4 is arranged on the wear-resistant layer 3. The base material layer 1 is made of stone powder and thermoplastic polymer material after being evenly stirred and then extruded at high temperature. The color film texture layer 2 is a decorative layer of various wood grains, stone grains, and carpet grains, which can meet the different needs of different occasions and different tastes. The material of the wear-resistant layer 3 is transparent PVC, which has strong adhesion and is wear-resistant and scratch-resistant. The UV layer 4 is a coating formed by curing UV paint, which can prevent ultraviolet rays from volatilizing the chemical substances in the board. The UV layer 4 is evenly attached to the wear-resistant layer 3 by spraying, and the spraying amount is 12-40g / m 2 .

[0031] A first locking portion 5 is provided at one end of the SPC body A, and a second locking portion 6 is provided at the other end of the SPC body A. The first locking portion 5 includes a first extension portion 5a, which is provided with a slot 5b. The second locking portion 6 includes a second extension portion 6a, which is provided with a tenon 6b. When the two SPC bodies A are assembled, the second extension portion 6a in one of the SPC bodies A is matched with the first extension portion 5a, and the tenon 6b is snapped into the slot 5b.

[0032] The lower end of the first locking portion 5 extends below the lower surface of the substrate layer 1. That is, a portion of the first locking portion 5 is located below the lower surface of the substrate layer 1. An assembly space 7 is formed between the lower surface of the substrate layer 1 and the lower surface of the first locking portion 5. The assembly space 7 is used to accommodate a shock-absorbing pad 8. The shock-absorbing pad 8 is located in the assembly space 7 and is fixed to the substrate layer 1. The material of the shock-absorbing pad 8 is rubber.

[0033] The thickness of the shock-absorbing pad 8 is equal to the distance between the lower surface of the first locking part 5 and the lower surface of the base material layer 1, or the difference between the thickness of the shock-absorbing pad 8 and the distance between the lower surface of the first locking part 5 and the lower surface of the base material layer 1 is less than 1 mm. In this embodiment, the difference between the thickness of the shock-absorbing pad 8 and the distance between the lower surface of the first locking part 5 and the lower surface of the base material layer 1 is 0.2 mm. After the shock-absorbing pad 8 is combined with the ground, there is a distance of 0.2 mm between the first locking part 5 and the ground. When a force acts on the shock-absorbing SPC floor, the shock-absorbing pad 8 will be subjected to the force first, thereby absorbing the vibration generated. Although there is a distance of 0.2 mm between the first locking part 5 and the ground, the shock-absorbing pad 8 will be compressed after being subjected to the force, and the size of the shock-absorbing pad 8 in the lateral direction is much larger than the size of the first locking part 5. Therefore, after the shock-absorbing pad 8 is compressed, the first locking part 5 will quickly fit into the ground, so that the shock-absorbing SPC floor is subjected to uniform force.

[0034] In addition, even if a gap is generated between the shock-absorbing SPC floor and the ground due to uneven ground, as can be seen from the above, due to the presence of the shock-absorbing pad 8, the shock-absorbing pad 8 is compressed after being subjected to force, thereby filling the gap and improving the uniformity of force on the shock-absorbing SPC floor.

[0035] The lower surface of the substrate layer 1 is provided with multiple rows of block components, and two adjacent rows of block components have a first inlay groove 1a arranged longitudinally along the substrate layer 1. Each row of block components includes multiple protrusions 1b, and there is a second inlay groove 1c arranged transversely along the substrate layer 1 between two adjacent protrusions 1b.

[0036] The upper surface of the shock-absorbing pad 8 is provided with a first clamping strip 9 arranged longitudinally along the shock-absorbing pad 8, and the upper surface of the shock-absorbing pad 8 is also provided with a second clamping strip 10 arranged transversely along the shock-absorbing pad 8. The first clamping strip 9 and the second clamping strip 10 intersect vertically and horizontally to form a clamping groove 11. When the shock-absorbing pad 8 is combined with the base material layer 1, the first clamping strip 9 cooperates with the first inlay groove 1a, the second clamping strip 10 cooperates with the second inlay groove 1c, and the clamping groove 11 cooperates with the protrusion 1b.

[0037] The first and second clips 9, 10 are made of polyurethane foam. Polyurethane foam offers advantages such as pre-foaming, high expansion, and minimal contraction. It also boasts excellent foam strength and high adhesion. Once cured, the foam provides multiple benefits, including caulking, bonding, sealing, heat insulation, and sound absorption. It is an environmentally friendly, energy-saving, and convenient building material suitable for sealing leaks, filling gaps, fixing, bonding, and providing thermal insulation and sound insulation. Therefore, the use of polyurethane foam in the first and second clips 9, 10 not only secures the shock-absorbing pad 8 to the substrate layer 1, but also provides heat insulation and sound absorption.

[0038] During the specific implementation, the mold is first placed on the shock-absorbing pad 8, and the foamed polyurethane is sprayed into the mold to form the first card strip 9 and the second card strip 10. Then the mold is removed. At this time, the first card strip 9 and the second card strip 10 are not completely dry, so the shock-absorbing pad 8 carrying the first card strip 9 and the second card strip 10 is then combined with the substrate layer 1 to fix the shock-absorbing pad 8 and the substrate layer 1 into one.
