Description

Technical Field

[0001] The utility model relates to the technical field of floors, in particular to a silent and wear-resistant PVC floor. Background Art

[0002] Existing PVC floors include a PVC layer, a wear-resistant layer, a sound-proof layer and a bottom plate layer. The upper surface of the PVC layer is fixed to the wear-resistant layer, the lower surface of the PVC layer is fixed to one end of the sound-proof layer, and the other end of the sound-proof layer is fixed to the bottom plate layer. PVC floors with this structure have the advantages of being quiet and wear-resistant. However, since the length and width of the sound-proof layer and the bottom plate layer are consistent with those of the PVC layer, the thickness of the PVC layer will inevitably be reduced after the sound-proof layer is set. Since the strength of the sound-proof layer is usually not as good as that of the PVC layer, the strength of the PVC floor with the above structure is lower than that of the structure consisting of the PVC layer and the wear-resistant layer alone. Therefore, the current problem is to ensure that the floor has corresponding strength while having quiet and wear-resistant properties. Utility Model Content

[0003] The utility model provides a silent and wear-resistant PVC floor. The utility model has better wear resistance and silent performance and also has higher performance.

[0004] The technical solutions to the above technical problems are as follows:

[0005] The silent and wear-resistant PVC floor includes a wear-resistant layer, a PVC layer, a silent layer, and a base plate. The lower surface of the wear-resistant layer is fixed to the upper surface of the PVC layer. The floor also includes a frame. The frame includes a frame and a crossbeam. The crossbeam is located in the frame and is fixed to the frame. The crossbeam divides the frame into multiple accommodating cavities. The silent layer is located in the accommodating cavity. The lower surface of the PVC layer is fixed to the frame, the crossbeam and the upper surface of the silent layer. The base plate is fixed to the frame, the crossbeam and the lower surface of the silent layer.

[0006] Furthermore, one end of the frame is provided with a plug-in groove, and the other end of the frame is provided with a protrusion for plugging.

[0007] Furthermore, it also includes a flame retardant layer, which is located between the PVC layer, the sound-proof layer and the frame, and is fixed to the PVC layer, the sound-proof layer and the frame respectively.

[0008] Furthermore, the flame retardant layer includes a first flame retardant part and a second flame retardant part. The first flame retardant part and the second flame retardant part are fixed. There is a step between the second flame retardant part and the first flame retardant part. A part of the first flame retardant part is located in the accommodating cavity and is fixed to the silent layer. Another part of the first flame retardant part is located outside the accommodating cavity and is fixed to the PVC layer. The second flame retardant part is located outside the accommodating cavity, and the second flame retardant part is fixed to the frame, beam and PVC layer respectively.

[0009] Furthermore, it also includes a moisture-proof layer, which is located between the sound-proof layer and the bottom plate, and is fixed to the sound-proof layer and the bottom plate respectively.

[0010] In the present invention, a frame is provided and the sound-proof layer is installed in the accommodating cavity of the frame. When a force acts on the floor, most of the force is borne by the frame, and only a small part of the force acts on the sound-proof layer. It can be seen that the present invention can enhance the strength while avoiding damage to the various functional layers in the floor. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figures 1 to 3 As shown, the silent and wear-resistant PVC floor of the present invention includes a wear-resistant layer 1, a PVC layer 2, a silent layer 3, and a base plate 4. The lower surface of the wear-resistant layer 1 is fixed to the upper surface of the PVC layer 2. It also includes a skeleton 5. The skeleton 5 includes a frame 5a and a crossbeam 5b. The crossbeam 5b is located in the frame 5a and is fixed to the frame 5a. The crossbeam 5b divides the frame 5a into multiple accommodating cavities 5c. The silent layer 3 is located in the accommodating cavity 5c. The lower surface of the PVC layer 2 is fixed to the frame 5a, the crossbeam 5b and the upper surface of the silent layer 3. The base plate 4 is fixed to the frame 5a, the crossbeam 5b and the lower surface of the silent layer 3.

[0022] In the present invention, the wear-resistant layer 1 is bonded and fixed to the PVC layer 2, the PVC layer 2 is bonded and fixed to the frame 5a, the beam 5b and the sound-proof layer 3, and the base plate 4 is bonded and fixed to the frame 5a, the beam 5b and the sound-proof layer 3. The adhesive used for the above bonding is epoxy glue.

[0023] In the present invention, the thickness of the wear-resistant layer 1 is 1 mm, the thickness of the PVC layer 2 is 3 to 4 mm, the thickness of the skeleton is 5-6 mm, the thickness of the silent layer 3 is 5-6 mm, and the thickness of the bottom plate 4 is 2-3 mm. The material of the bottom plate 4 is preferably the same as that of the PVC layer 2, and the material of the skeleton 5 is preferably the same as that of the PVC layer 2.

[0024] In the present invention, a skeleton 5 is provided and the sound-proof layer 3 is installed in the accommodating cavity 5c of the skeleton 5. When a force acts on the floor, most of the force is borne by the skeleton 5, and only a small part of the force acts on the sound-proof layer 3. It can be seen that the present invention can enhance the strength while avoiding damage to the various functional layers in the floor.

[0025] One end of the frame 5a is provided with a groove 5d for insertion, and the other end of the frame 5a is provided with a protrusion 5e for insertion. When two adjacent floorboards are assembled, the protrusion 5e on one floorboard is inserted and matched with the groove 5d on the other floorboard, so that the two adjacent floorboards form a tight fit.

[0026] The present invention also includes a flame-retardant layer positioned between the PVC layer 2, the sound-reducing layer 3, and the frame 5. The flame-retardant layer is secured to the PVC layer 2, the sound-reducing layer 3, and the frame 5, respectively. The flame-retardant layer serves to prevent the floor from fire. Asbestos is preferably used as the material for the flame-retardant layer. The flame-retardant layer is secured to the PVC layer 2, the sound-reducing layer 3, and the frame 5, respectively, using epoxy adhesive.

[0027] The flame retardant layer includes a first flame retardant part 6 and a second flame retardant part 7. The first flame retardant part 6 and the second flame retardant part 7 are fixed. There is a step between the second flame retardant part 7 and the first flame retardant part 6. A part of the first flame retardant part 6 is located in the accommodating cavity 5c and is fixed to the silent layer 3. Another part of the first flame retardant part 6 is located outside the accommodating cavity 5c and is fixed to the PVC layer 2. The second flame retardant part 7 is located outside the accommodating cavity 5c, and the second flame retardant part 7 is fixed to the frame 5a, the beam 5b and the PVC layer 2 respectively.

[0028] The system also includes a moisture-proof layer 8, which is positioned between the sound-reducing layer 3 and the base plate 4 and secured to both layers. The moisture-proof layer 8 is bonded to both layers using epoxy adhesive. The moisture-proof layer 8 is made of rigid PVC, a material with excellent waterproof properties. The moisture-proof layer 8 also contains an insecticidal fragrance, which effectively inhibits the growth of pests.

[0029] After setting the flame retardant layer and moisture-proof layer 8, since the height of the accommodating cavity 5c is fixed, and the flame retardant layer and moisture-proof layer 8 will occupy the corresponding height, the thickness of the silent layer 3 is thinned. In the present utility model, the thickness of the flame retardant layer and moisture-proof layer 8 are both 1-2 mm.
