Description

Technical Field

[0001] This utility model relates to the field of flooring technology, specifically to a polymer SPC co-extruded flooring. Background Technology

[0002] Stone-plastic composite flooring (SPC) is a new type of environmentally friendly flooring material, mainly composed of stone powder and high-molecular plastic resin, and is manufactured using an extrusion-calendering composite process. SPC flooring combines the hardness of stone with the flexibility of plastic, offering both durability and aesthetics.

[0003] In related technologies, a search revealed a solution for a multi-layer co-extruded SPC flooring (publication number CN213174621U), in which tongues and grooves are provided on both sides of the flooring width direction. When laying the flooring, the tongues and grooves are used to assemble the flooring and complete the interlocking of adjacent flooring.

[0004] The tongue and groove and tenon used in the above-mentioned flooring are widely used in flooring. Because such an assembly structure is part of the flooring itself and its thickness cannot be the same as the flooring, the strength of the tongue and groove and tenon structure is limited. After the flooring is assembled, when stepping on the floor, the joint of the tongue and groove is prone to deformation and friction with each other, resulting in noise when stepping on the floor. Utility Model Content

[0005] The purpose of this invention is to provide a polymer SPC co-extruded flooring to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A type of SPC co-extruded flooring includes stone plastic flooring. The lower left side of the stone plastic flooring has a protruding buckle with a trapezoidal receiving groove and a beveled slot inside. The upper right side of the stone plastic flooring has a beveled buckle that matches the beveled slot, with a snap-fit ​​groove matching the protruding buckle inside. The beveled slot and beveled buckle guide the splicing of two stone plastic flooring pieces. This reduces the difficulty of stone plastic flooring installation. After splicing, the stone plastic flooring is firmly secured, preventing lateral shifting and unevenness. A buffer strip is installed on the upper surface of the angled buckle. The buffer strip has an angled surface that matches the angled slot. The surface of the buffer strip is provided with a buffer groove, which can provide support and buffer for the angled buckle. The support strip is installed on the lower surface of the angled buckle. The lower part of the support strip has an angled edge that matches the trapezoidal receiving groove. The support strip has a buffer hole inside. When two pieces of stone plastic flooring are spliced ​​together, the buffer strip and the support strip fill the gap. The buffer hole inside the support strip can distribute the overall force of the flooring, avoid the convex buckle and the angled buckle from rubbing against each other, and reduce the noise when stepping on it.

[0007] Furthermore, the lower surface of the stone plastic flooring is provided with a sound-absorbing pad, and the surface of the sound-absorbing pad is provided with several fixing grooves to improve the connection strength between the sound-absorbing pad and the stone plastic flooring. The surface of the sound-absorbing pad is provided with several sound-absorbing holes, which are staggered from the fixing grooves, to reduce friction noise and impact noise between the stone plastic flooring and the ground, such as the sound generated by falling objects or vibrations from walking, thus meeting the application scenarios with high requirements for quietness.

[0008] Furthermore, the protruding buckle has an integrally formed semi-circular strip, the size of which matches the interlocking groove. The semi-circular strip can improve the smoothness of the splicing of the stone plastic flooring, avoid the problem of jamming, and guide the alignment direction of the protruding buckle and the interlocking groove, making the installation of stone plastic flooring more convenient.

[0009] Furthermore, the angled buckle has a placement groove, and the placement groove has a card slot inside. The support strip has a card strip on its side, and the card strip engages with the card slot. The engagement structure of the card slot and the card strip can quickly fix the support strip without the need for additional glue, making the assembly of the support strip convenient and quick.

[0010] Furthermore, the angled buckle has an arc-shaped anti-detachment groove, and the lower surface of the buffer strip has an arc-shaped anti-detachment strip that inserts into the arc-shaped anti-detachment groove. Pressing the buffer strip causes the arc-shaped anti-detachment strip to snap into the arc-shaped anti-detachment groove, which also eliminates the need for glue and helps improve the construction efficiency of stone plastic flooring.

[0011] Furthermore, the upper surface of the convex buckle is provided with a limiting edge, and the lower surface of the oblique buckle is provided with a limiting strip corresponding to the limiting edge. After the stone plastic flooring is installed, the oblique buckle is supported by the convex buckle, preventing the oblique buckle from bending due to stepping, and the gaps between the stone plastic flooring panels are not easy to widen.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The convex and oblique buckles are supported and buffered by the support strip and the buffer strip. The convex and oblique buckles support each other and are not easily deformed. When stepping on the convex and oblique buckles, the support strip and the buffer strip reduce the contact area between them. The friction between the support strip and the buffer strip and the convex buckle will not produce noise, which can reduce the noise caused by the deformation of the stone plastic flooring due to stepping. The stone plastic flooring has a better sound insulation effect.

[0013] (2) Both the support strip and the buffer strip are in a snap-fit ​​state. The support strip and the buffer strip can be pre-installed into the angled buckle without the need for later assembly. When assembling the stone plastic floor, the angled buckle is directly inserted into the angled slot. The angled slot and the semi-circular strip can guide the angled buckle. The stone plastic floor is easy to assemble, and the side of the stone plastic floor is neatly assembled. After the stone plastic floor is laid, the surface is flat.

[0014] (3) The sound-absorbing pad can reduce the noise of the stone plastic floor being hit, and the sound-absorbing holes can absorb some of the sound energy, prevent the sound from being transmitted through the ground structure, and reduce indoor environmental noise. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Please see Figures 1-6 This utility model provides a technical solution: a polymer SPC co-extruded floor, including stone plastic floor 1, buffer strip 14, and support strip 13. The buffer strip 14 and support strip 13 are made of flexible materials, such as rubber, which can reduce the creaking sound of the stone plastic floor 1. The lower left side of the stone plastic floor 1 is provided with a protruding buckle 2. The protruding buckle 2 has a trapezoidal receiving groove 9 and a beveled slot 10 inside. The upper right side of the stone plastic floor 1 is provided with a beveled buckle 4 that matches the beveled slot 10. The beveled buckle 4 has a snap-fit ​​groove 11 that matches the protruding buckle 2 inside. The beveled slot 10 and the beveled buckle 4 guide the splicing of two stone plastic floor 1 pieces. When assembling the stone plastic floor 1, it is tilted first, which can quickly assemble the stone plastic floor 1. The assembly operation is simple. The protruding buckle 2 and the beveled buckle 4 interlock with each other, which can ensure the stability of the stone plastic floor 1 after assembly and prevent the problem of warping or unevenness. The buffer strip 14 is installed on the upper surface of the inclined buckle 4. The buffer strip 14 has an inclined surface that matches the inclined slot 10. The surface of the buffer strip 14 is provided with a buffer groove 19. The buffer strip 14 supports the inclined surface of the inclined slot 10. When the inclined slot 10 is stepped on, it is flexibly supported by the buffer strip 14 to prevent the inclined slot 10 and the inclined buckle 4 from rubbing against each other and to reduce noise. The support strip 13 is installed on the lower surface of the angled buckle 4. The lower part of the support strip 13 has an angled edge that matches the trapezoidal receiving groove 9. The support strip 13 has a buffer hole 18 inside. Two stone plastic flooring pieces 1 are spliced ​​together so that the buffer strip 14 and the support strip 13 fill the gap. After the gap is filled, it can ensure that the angled buckle 4 is not easily deformed by stepping. The deformation of the angled buckle 4 is minimal. At the same time, the support strip 13 separates the protruding buckle 2 and the angled buckle 4, which makes it less likely to cause friction noise.

[0019] In this embodiment, as Figure 1 and Figure 2 As shown, the lower surface of the stone plastic flooring 1 is provided with a sound-absorbing pad 3. The surface of the sound-absorbing pad 3 is provided with several fixing grooves 5. Environmentally friendly hot melt adhesive (such as EVA hot melt adhesive, PU hot melt adhesive, etc., which are formaldehyde-free and have strong adhesion) is applied to the fixing grooves 5. This can accommodate the hot melt adhesive, prevent the hot melt adhesive from flowing, and ensure the flatness of the sound-absorbing pad 3 after it is bonded to the stone plastic flooring 1. This ensures the flatness of the stone plastic flooring 1 after installation. The surface of the sound-absorbing pad 3 is provided with several sound-absorbing holes 6. The sound-absorbing holes 6 are staggered from the fixing grooves 5 to prevent the sound-absorbing holes 6 from being blocked by hot melt adhesive. In scenarios such as jumping on the stone plastic flooring 1 or objects falling on the stone plastic flooring 1, the sound generated is transmitted to the sound-absorbing pad 3 and the sound-absorbing holes 6. The sound-absorbing holes 6 and the sound-absorbing pad 3 absorb some of the sound energy, thereby reducing noise.

[0020] In this embodiment, as Figure 3 and Figure 5 As shown, the convex buckle 2 has an integrally formed semi-circular strip 7. The size of the semi-circular strip 7 matches the interlocking groove 11. The surface of the semi-circular strip 7 is smoothly rounded. When assembling the stone plastic flooring 1, the interlocking groove 11 will not be stuck by the semi-circular strip 7, and the stone plastic flooring 1 can be assembled smoothly. The upper surface of the convex buckle 2 is provided with a limiting edge 8, and the lower surface of the oblique buckle 4 is provided with a limiting strip 12 corresponding to the limiting edge 8. The limiting edge 8 and the limiting strip 12 support each other, which can prevent the oblique buckle 4 from bending due to heavy pressure, and the structure at the joint of the stone plastic flooring 1 is stable.

[0021] In this embodiment, as Figure 4As shown, the angled buckle 4 has a placement groove 15, and the placement groove 15 has a slot 16 inside. The support strip 13 has a locking strip 17 on its side, and the locking strip 17 engages with the slot 16. The angled buckle 4 has an arc-shaped anti-detachment groove 20. The lower surface of the buffer strip 14 has an arc-shaped anti-detachment strip 21 that engages with the arc-shaped anti-detachment groove 20. During installation, simply align the support strip 13 with the placement groove 15 and press it down, and the locking strip 17 will engage with the slot 16. Similarly, pressing the buffer strip 14 will allow the arc-shaped anti-detachment strip 21 to enter the arc-shaped anti-detachment groove 20. The support strip 13 and the buffer strip 14 are easy to pre-install. During the assembly of the stone plastic flooring 1, the support strip 13 and the buffer strip 14 are not easy to fall off, and will not affect the assembly difficulty and efficiency of the stone plastic flooring 1.

[0022] Specifically, when assembling stone-plastic flooring 1, such as Figure 5 Lay out the stone plastic flooring 1, and assemble the subsequent stone plastic flooring 1. First, hold the stone plastic flooring 1 at an angle, align the angled buckle 4 with the angled slot 10, and then while laying the stone plastic flooring 1 flat, push the angled buckle 4 into the angled slot 10 to achieve the splicing of the protruding buckle 2 and the angled buckle 4. The buffer strip 14 fills the gap in the inclined slot 10, and the support strip 13 provides flexible support for the convex buckle 2 and the inclined buckle 4. When the stone plastic floor 1 is subjected to pressure, because the gap is filled by the buffer strip 14, the convex buckle 2 and the inclined buckle 4 are not easily deformed and rub against each other, which can prevent the sound generated by the friction between the convex buckle 2 and the inclined buckle 4, thereby reducing the creaking sound when stepping on the stone plastic floor 1; combined with the sound insulation pad 3 and the sound absorption hole 6 to absorb sound energy, the stone plastic floor 1 has good overall sound insulation performance.

[0023] After the support strips 13 and buffer strips 14 fill the gaps of the stone plastic flooring 1, they also prevent dust, water and other substances from entering under the stone plastic flooring 1, reducing the risk of damage to the stone plastic flooring 1 and extending its service life.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
