[0002] Fireproof panels are a type of material specifically designed to improve the fire resistance of buildings. By using special materials and processes, they can effectively prevent the spread of fire in the event of a fire, buying valuable time for evacuation and fire rescue.

[0003] In recent years, building fires have become increasingly common, and the root cause is often related to the inadequate fire resistance of building materials. Traditional building materials often accelerate the spread of fire when exposed to fire, posing a safety hazard. To address this challenge, rock wool board, due to its cost-effectiveness and excellent thermal insulation and flame-retardant properties, has been widely adopted in many construction projects and is highly favored by workers. However, these boards all share a common characteristic: poor waterproofing, significantly weakening the sealing and joint strength of the board joints. To address this, we have developed a new flame-retardant and waterproof composite PVC board. Utility Model Content

A docking groove 28 is provided on the upper side of the top dovetail strip 23 and the side of the side dovetail strip 22, and a dovetail groove 29 is provided on the inner side of the docking groove 28. The top dovetail strip 23 and the side dovetail strip 22 are both provided with an installation groove 26, and a sealing strip 27 is inserted into the inner side of the installation groove 26. A side guard bite groove 24 is provided on the lower side of the edge connecting strip 21, and the side guard bite groove 24 and the docking groove 28 are both engaged with the outer edge of the composite PVC sheet 1.

[0024] In this embodiment, the composite PVC board 1 includes a PVC base board 11 , fire-retardant boards 13 are provided on both sides of the PVC base board 11 , and a waterproof adhesive layer 12 is provided between the fire-retardant boards 13 and the PVC base board 11 .

[0025] Through the above-mentioned arrangement, the PVC base plate 11 has structural strength and a certain toughness, and it itself has waterproof properties. The waterproof adhesive layer 12 enables the outer fire-retardant board 13 to form an effective structural bonding effect with the PVC base plate 11.

[0026] In this embodiment, the fire-retardant board 13 is made of silicate board.

[0027] Through the above-mentioned setting, the silicate board is an inorganic non-metallic material, the main components of which are silicate and cellulose, etc. It has good fire resistance and impact resistance, and can maintain stable physical properties in high temperature environments.

[0028] In this embodiment, a plurality of transverse ribs 14 and vertical ribs 15 are provided on both sides of the PVC base plate 11 , and the transverse ribs 14 and vertical ribs 15 are arranged in a cross shape.

[0029] Through the above arrangement, the plurality of transverse ribs 14 and the vertical ribs 15 are arranged in a cross pattern, thereby improving the structural strength of the PVC base plate 11 .

[0030] In this embodiment, the side edges of the edge protection bite groove 24 and the docking groove 28 are screwed through a plurality of connecting screws 25 , and the edge protection bite groove 24 and the docking groove 28 are fixedly connected to the outer edge of the composite PVC board 1 through the connecting screws 25 .

[0031] By the above-mentioned arrangement, the edge protection engaging groove 24 and the docking groove 28 are fixedly connected to the outer edge of the composite PVC board 1 through the connecting screw 25, so that it is convenient to disassemble. The disassembly can be completed by loosening the connecting screw 25, which provides convenience for the subsequent material recycling.

[0032] In this embodiment, the outer end of the connecting screw 25 is fixedly connected to a screw cap 251 , and the other end of the connecting screw 25 is threadedly installed with a docking nut 252 . A sealing gasket 253 is provided on the inner side of the screw cap 251 and the docking nut 252 .

[0033] Through the above-mentioned arrangement, the sealing gasket 253 is arranged on the inner side of the screw cap 251 and the docking nut 252, so that when the connecting screw 25 is connected to the side of the composite PVC board 1, both sides of the screw connection of the composite PVC board 1 are sealed by the sealing gasket 253, so that the screw connection point also has waterproof sealing, ensuring the overall waterproof sealing.

[0034] In this embodiment, a positioning screw 210 is threadedly installed at the end of the docking groove 28 , and the positioning screw 210 is threadedly passed through the inner side of the dovetail groove 29 .

[0035] By setting in the above manner, tightening the positioning screw 210 causes the inner end of the positioning screw 210 to abut against the dovetail bar, thereby completing the splicing, fixing and limiting function.

[0036] In this embodiment, the sealing strip 27 and the sealing gasket 253 are both made of silicone.

[0037] Through the above-mentioned configuration, the silicone has good high temperature resistance and flexibility, is not easy to age, and can maintain its good sealing physical properties within the temperature range of -60°C to +250°C.

[0038] The working principle of the novel flame-retardant and waterproof composite PVC sheet provided by the utility model is as follows:

[0039] During use, the fire-retardant board 13 on the outside of the composite PVC board 1 provides waterproof performance, while the waterproof adhesive layer 12 and the PVC base board 11 on the inside provide good waterproof performance. The fire-retardant board 13 is set on both sides, so that the composite PVC board 1 has double-sided fireproof and waterproof performance. When installing the composite PVC board 1, the edge guard bite groove 24 and the docking groove 28 can be screwed and installed on the side of the board in advance according to the installation method of assembly. Subsequently, the dovetail strip with the edge guard bite groove 24 will be installed and slid into the inside of the dovetail groove 29. After the insertion is completed and positioned, the positioning screw 210 is tightened so that the inner end of the positioning screw 210 abuts against the dovetail strip, thereby completing the splicing fixed limiting function. During splicing, the inner sealing strip 27 and the sealing gasket 253 at the screw connection function ensure the waterproof sealing performance of the splicing.
