Description
Technical Field
[0001] This utility model relates to the field of flooring technology, specifically to a multi-layer low-foaming SPC floor with a built-in reinforcing core. Background Technology
[0002] As people's living standards improve, they are paying more attention to interior decoration. As a result, flooring is being used in various indoor spaces, such as living rooms and bedrooms. People are pursuing environmental protection and health while also focusing on texture, stability, and compatibility. At the same time, the high-end decoration market is increasing its demand for the fineness of floor texture and the precision of patterns. Although traditional solid wood flooring has a good texture, it relies heavily on large-diameter timber for processing and manufacturing, which exacerbates resource shortages. In addition, solid wood flooring has extremely poor water and moisture resistance, and it is prone to swelling and cracking when exposed to water, and daily maintenance is extremely difficult. The core material of laminate flooring is mostly high-density fiberboard, which relies heavily on glue in production and is prone to releasing harmful substances. Early PVC flooring had problems such as insufficient wear resistance and poor sound insulation. The joints were prone to shaking and separation, and it was also prone to bending and deformation after long-term use, making it inconvenient to use and easily damaged. Utility Model Content
[0003] The purpose of this invention is to provide a multi-layer low-foaming SPC floor with a built-in reinforcing core to solve the problem mentioned in the background art that the floor is prone to bending and deformation, leading to damage.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer low-foaming SPC floor with an internal reinforcing core, comprising a low-foaming substrate, threaded holes uniformly formed on one side of the low-foaming substrate, a colored film layer inlaid and fixed on one side of the low-foaming substrate, a high-strength fiber material inlaid and fixed inside the low-foaming substrate, and a glass fiber layer fixedly disposed inside the high-strength fiber material, the high-strength fiber material and the glass fiber layer being tightly bonded together, and the glass fiber layer having a mesh design.
[0005] Preferably, the outer surface of the color filter layer is uniformly sprayed and adhered with a wear-resistant layer, and the outer surface of the wear-resistant layer is coated and fixed with an anti-slip layer, the anti-slip layer containing particles.
[0006] By adopting the above technical solution, the wear-resistant layer can improve the overall wear resistance of the floor, while the particles mixed in the anti-slip layer can further improve the wear resistance of the floor, reduce the wear resistance and anti-slip properties of the floor during use, and reduce the chance of slipping and falling when the floor is wet.
[0007] Preferably, a plastic underlayer is fixedly glued to the side of the low-foaming substrate away from the anti-slip layer, and a reinforcing rib is provided on the side of the plastic underlayer away from the color film layer.
[0008] By adopting the above technical solution, the overall strength of the floor can be further improved by the plastic base layer and reinforcing ribs, and the probability of the floor bending and deforming can be further reduced. At the same time, the probability of the low foaming substrate being worn down after long-term use can also be reduced.
[0009] Preferably, a sound-absorbing pad is fixedly attached to the outer surface of the plastic base layer, and ventilation grooves are evenly formed on the outer surface of the sound-absorbing pad.
[0010] By adopting the above technical solution, the sound-absorbing pad can improve the floor's shock absorption, sound insulation and cushioning, as well as improve the comfort underfoot and the floor's durability. It can also compensate for unevenness of the ground during installation to a certain extent, and the ventilation channels ensure the ventilation between the sound-absorbing pad and the ground, reducing mold damage caused by moisture under the floor and reducing noise transmission.
[0011] Preferably, threaded holes are uniformly formed on one side of the low-foaming substrate, and insertion holes are uniformly formed on the side of the low-foaming substrate away from the threaded holes, and the insertion holes and threaded holes are concentrically designed.
[0012] By adopting the above technical solution, the flatness of both sides of the low-foaming substrate can be guaranteed, so that the flooring will not be damaged by bumps during transportation and cannot be spliced.
[0013] Preferably, a bolt is installed in the internal thread of the threaded hole, and the outer surface of the bolt is hexagonal. A flower-shaped spring is fixedly provided on the outer surface of the bolt, and a snap-fit opening mechanism is provided between the flower-shaped spring and the insertion hole.
[0014] By adopting the above technical solution, the flower-shaped spring and bolt can be flexibly installed and fixed into the threaded hole. The hexagonal design allows the bolt to be easily installed on one side of the low-foaming substrate, greatly improving the convenience and flexibility of installation. It can also be easily replaced after damage. The flower-shaped spring itself is elastic and will continuously generate radial elastic force after installation to tightly fit the inner wall of the insertion hole, fill the gap, and avoid loosening caused by vibration and displacement during long-term use.
[0015] Preferably, the buckle opening mechanism includes: an expansion plug, which is fixedly disposed inside the insertion hole, and the insertion hole and the expansion plug are designed in the same way. The expansion plug is tapered, and the outer surface of the expansion plug is in contact with the inner surface of the flower-shaped spring. A wedge pin is fixedly provided at the end of the flower-shaped spring away from the bolt. A locking groove is provided inside the insertion hole, and the locking groove engages with the wedge pin.
[0016] Using the above technical solution, when the flower-shaped spring is inserted into the insertion hole and the expansion plug is inserted into the flower-shaped spring, the flower-shaped spring can expand and the wedge pin can be engaged in the locking groove, ensuring the uniformity of force after the floor is spliced and further improving the firmness of the spliced floor.
[0017] Compared with the prior art, the beneficial effects of this utility model are: the multi-layer low-foaming SPC floor with built-in reinforcing core:
[0018] 1. By combining high-strength fiber materials with the fiberglass layer, and with the grid design of the fiberglass layer, the flooring becomes more resilient. At the same time, the properties of the fiberglass layer itself can further reduce the weight of the flooring, thereby enhancing the overall strength and rigidity of the flooring and effectively preventing the flooring from bending and deforming and being damaged during use.
[0019] 2. The use of a plastic base layer and reinforcing ribs can effectively reduce the chance of wear and tear on the low-foaming substrate after prolonged use, while also further enhancing the floor's toughness to prevent deformation. The use of sound-absorbing pads can effectively reduce the transmission of vibration and noise when walking on the floor. Combined with the use of ventilation channels, ventilation can be achieved between the sound-absorbing pads and the ground, reducing the chance of the sound-absorbing pads becoming moldy, damaged, or ineffective. It can also slightly eliminate unevenness on the ground, further reducing the chance of the floorboards shaking and separating at the joints.
[0020] 3. When assembling the floor, simply screw the bolts into the threaded holes, then insert the patterned spring into the insertion hole of another low-foaming substrate. The expansion plug can be inserted into the patterned spring and deformed, allowing the wedge pin to engage in the locking groove, further strengthening the connection strength of the patterned spring inserted into the insertion hole and reducing the chance of the floor loosening during use.

[0028] 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.
[0029] Please see Figures 1-6 This utility model provides a technical solution: a multi-layer low-foaming SPC floor with built-in reinforcing core, including a low-foaming substrate 1, threaded holes 8 uniformly opened on one side of the low-foaming substrate 1, a colored film layer 4 inlaid and fixed on one side of the low-foaming substrate 1, a high-strength fiber material 2 inlaid and fixed inside the low-foaming substrate 1, and a glass fiber layer 3 fixedly disposed inside the high-strength fiber material 2, the high-strength fiber material 2 and the glass fiber layer 3 are tightly bonded, and the glass fiber layer 3 is designed in a grid pattern.
[0030] Firstly, the high-strength fiber material 2 wraps around the glass fiber layer 3. Through the mesh design and material of the glass fiber layer 3, the low-foaming substrate 1 becomes more resilient. The weight of the floor is reduced by the material of the glass fiber layer 3 and the high-strength fiber material 2. The floor is sturdy, resilient, and deformation-resistant while reducing its own weight, so that the floor will not deform and be damaged after long-term use.
[0031] The outer surface of the color film layer 4 is uniformly sprayed and adhered with a wear-resistant layer 5, and the outer surface of the wear-resistant layer 5 is coated and fixed with an anti-slip layer 6. The anti-slip layer 6 contains particles. The side of the low-foaming substrate 1 away from the anti-slip layer 6 is fixedly glued with a plastic bottom layer 7, and the side of the plastic bottom layer 7 away from the color film layer 4 is provided with reinforcing ribs. The outer surface of the plastic bottom layer 7 is fixedly pasted with a sound-absorbing pad 9, and the outer surface of the sound-absorbing pad 9 is uniformly provided with ventilation grooves 10.
[0032] Secondly, the color film layer 4 can replicate various patterns, providing rich decorative effects for the floor. The wear-resistant layer 5 can prevent the pattern of the color film layer 4 from being erased, and the anti-slip layer 6 can reduce the chance of slipping and falling when the floor is wet. At the same time, the design of the plastic bottom layer 7 and the reinforcing ribs can further enhance the wear resistance and toughness of the floor. Meanwhile, the use of the sound-absorbing pad 9 can reduce the transmission of noise and vibration when walking on the floor, and the ventilation channel 10 can facilitate the circulation of air between the sound-absorbing pad 9 and the ground, reducing the chance of the sound-absorbing pad 9 and the floor being damaged by moisture.
[0033] A threaded hole 8 is uniformly formed on one side of the low-foaming substrate 1, and a insertion hole 14 is uniformly formed on the side of the low-foaming substrate 1 away from the threaded hole 8. The insertion hole 14 and the threaded hole 8 are concentrically designed. A bolt 11 is installed inside the threaded hole 8, and the outer surface of the bolt 11 is hexagonal. A flower-shaped spring piece 12 is fixedly set on the outer surface of the bolt 11. A snap-fit expansion mechanism is set between the flower-shaped spring piece 12 and the insertion hole 14. The snap-fit expansion mechanism includes a plug 15, which is fixedly set inside the insertion hole 14. The insertion hole 14 and the plug 15 are designed in the same way. The plug 15 is tapered, and the outer surface of the plug 15 is in contact with the inner surface of the flower-shaped spring piece 12. A wedge pin 13 is fixedly formed at the end of the flower-shaped spring piece 12 away from the bolt 11. A locking groove 16 is formed inside the insertion hole 14, and the locking groove 16 engages with the wedge pin 13.
[0034] Furthermore, when assembling the floor, simply screw the bolt 11 into the threaded hole 8, insert the flower-shaped spring 12 into the insertion hole 14 of the other floor, and allow the expansion plug 15 to be inserted into the flower-shaped spring 12, so that the flower-shaped spring 12 can deform and the wedge pin 13 can be engaged into the locking groove 16. Through the double fixing of insertion and expansion locking, the two floorboards can be firmly fixed together, greatly improving the convenience and firmness of floor installation.
[0035] Working principle: When laying the floor, simply place the first floorboard on the ground, ensuring the sound-absorbing pad 9 is in contact with the ground and aligned with the wall. Then, screw the bolts 11 into the threaded holes 8 one by one, and insert the flower-shaped spring clips 12 into the insertion holes 14 in the floorboard. This allows the expansion plug 15 to be inserted into the flower-shaped spring clips 12 and expand, enabling the wedge pins 13 to engage with the locking grooves 16 for quick connection and fixation. This allows the two floorboards to be tightly and firmly connected together, reducing the chance of deformation at the connection point during use. Furthermore, the use of high-strength fiber material 2 and glass fiber layer 3 enhances the overall strength and toughness of the floor, reducing the chance of the floor bending and deforming and being damaged after prolonged use.
[0036] 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.
