Description

Technical Field

[0001] This invention belongs to the field of insulation board technology, and specifically relates to a fireproof core layer reinforced rock wool insulation board. Background Technology

[0002] Insulation boards, as the name suggests, are boards used for heat insulation. They are commonly used in construction, typically installed on exterior walls or interior structures to reduce heat loss from the building's interior to the outside, thus maintaining indoor temperatures. The main structure of an insulation board includes an insulation layer and a decorative layer (protective layer). During manufacturing, rock wool, with its excellent fire resistance, heat insulation, sound absorption, and thermal insulation properties, along with EPDM rubber, which boasts excellent waterproof and moisture-proof performance and good heat insulation properties, and is modified to be flame-retardant, are often used together to form a composite insulation layer. This provides better insulation and expands its applicability. Polyvinyl chloride (PVC), due to its inherent flame retardancy, is often used as the decorative layer in insulation boards for locations with high fire safety requirements.

[0003] However, in existing technologies, the insulation boards are not connected to each other during manufacturing and installation; they are simply fixed to the wall. This affects the stability of the insulation boards and their normal use. Furthermore, the layers of existing insulation boards are usually bonded together, making it difficult to separate and recycle the layers when the insulation boards are removed. To address these issues, designing a fire-resistant core-reinforced rock wool insulation board is a problem we need to solve. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fireproof core-reinforced rock wool insulation board.

[0005] To achieve the above objectives, the present invention provides a fireproof core layer reinforced rock wool insulation board, comprising a first PVC board and a second PVC board. Connecting blocks are fixedly connected to the four corners of the opposite side of the first PVC board and the second PVC board, and the outer contour of one corner fixedly connected connecting block is larger than the outer contour of the other connecting blocks. A fireproof rock wool core material is provided between the first PVC board and the second PVC board. PVC mesh frames are provided on both sides of the fireproof rock wool core material. EPDM rubber sheets are provided on the side of each of the two PVC mesh frames away from the fireproof rock wool core material. The two EPDM rubber sheets abut against the first PVC board and the second PVC board respectively.

[0006] A fixing component is used to connect and fix multiple insulation boards, and the fixing component is connected to the first PVC board and the second PVC board;

[0007] The mounting component is used to assemble and fix the insulation board, and the mounting component is connected to the second PVC board and the connecting block.

[0008] In the above technical solution, the fixing component further includes two pairs of first clamping plates and first insert plates fixedly installed on the side of the first PVC board near the second PVC board, and two pairs of second clamping plates and second insert plates fixedly installed on the side of the second PVC board near the first PVC board. One pair of first clamping plates and first insert plates is fixedly connected to a set of opposite sides on the side of the first PVC board near the second PVC board. Another pair of first clamping plates and first insert plates is fixedly installed on another set of opposite sides on the side of the first PVC board near the second PVC board. A pair of second clamping plates and second insert plates is fixedly installed on a set of opposite sides on the side of the second PVC board near the first PVC board. Another pair of second clamping plates and second insert plates is fixedly installed on another set of opposite sides on the side of the second PVC board near the first PVC board.

[0009] In the above technical solution, a first weakening groove is provided on both sides of the first card plate and the second card plate, and a second weakening groove is provided on one side of the first insert plate and the second insert plate.

[0010] In the above technical solution, the first card plate and the second card plate are further provided with a plurality of first card slots and second card slots inside, and the plurality of first card slots and second card slots are provided in a non-equidistant linear array state inside the corresponding first card plate and the second card plate.

[0011] In the above technical solution, a first card block and a second card block are fixedly installed on the opposite side of the first insert plate and the second insert plate. The number and position of the first card block and the second card block correspond one-to-one with the first card slot and the second card slot on the first card plate and the second card plate. The inner contour of the first card slot is adapted to the outer contour of the first card block, and the inner contour of the second card slot is adapted to the outer contour of the second card block. The outer walls of the first card block and the second card block are provided with guide rounded corners.

[0012] In the above technical solution, the installation component further includes a plurality of first elastic strips fixedly connected to the connecting block of the first PVC board near the side of the second PVC board. The plurality of first elastic strips are arranged in a circumferential array, and triangular clips are fixedly connected to the outer wall of each of the plurality of first elastic strips.

[0013] In the above technical solution, a first circular hole is formed inside the connecting block of the second PVC board, and a second circular hole is formed inside the second PVC board. The inner contour of the first circular hole is smaller than the inner contour of the second circular hole, and the first circular hole and the second circular hole are connected.

[0014] In the above technical solution, the first elastic strip is inserted into the inside of the first circular hole, the triangular block is inserted into the inside of the second circular hole, a circular plate is inserted between the multiple triangular blocks, and multiple second elastic strips are fixedly connected in a circumferential array on the side of the circular plate away from the first PVC board, and the multiple second elastic strips are fixedly installed on the inner wall of the second circular hole.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By setting up fixing components, multiple insulation boards can be snapped together when they are installed together, so that the multiple insulation boards can support and fix each other, improving the overall stability of the insulation boards after installation and preventing the insulation boards from detaching from the wall.

[0017] By setting up fixing components, the thickness and composition of the internal insulation layer can be adjusted according to needs before assembly to adapt to different insulation requirements. After adjusting the insulation layer, the fixing components are used to assemble and lock the first PVC board, the second PVC board and the insulation layer together, preventing the insulation board from separating during use and affecting its normal use. At the same time, after the insulation board is discarded and removed from the wall, it can be disassembled layer by layer for classified recycling, improving the recycling rate and reducing the difficulty of recycling.

Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 6 The fireproof core-reinforced rock wool insulation board shown includes a first PVC board 1 and a second PVC board 2. Connecting blocks 3 are fixedly connected to the four corners of the facing sides of the first PVC board 1 and the second PVC board 2, with the outer contour of one corner-fixed connecting block 3 being larger than the outer contours of the other connecting blocks 3. A fireproof rock wool core material 4 is disposed between the first PVC board 1 and the second PVC board 2. PVC mesh frames 5 are disposed on both sides of the fireproof rock wool core material 4. EPDM rubber sheets 6 are disposed on the side of each of the two PVC mesh frames 5 away from the fireproof rock wool core material 4, and the two EPDM rubber sheets 6 abut against the first PVC board 1 and the second PVC board 2 respectively. A fixing component is used to connect and fix multiple insulation boards, and the fixing component is connected to the first PVC board 1 and the second PVC board 2. An installation component is used to assemble and fix the insulation boards, and the installation component is connected to the second PVC board 2 and the connecting blocks 3.

[0027] Specifically, by setting the connecting block 3 on one corner of the first PVC board 1 and the second PVC board 2 to be larger than the other connecting blocks 3, the connecting block 3 can play a positioning and guiding role when the workers connect the first PVC board 1 and the second PVC board 2 together, so as to avoid misalignment when the first PVC board 1 and the second PVC board 2 are connected and installed together, which would cause the first clip 7 and the first insert 8 on the first PVC board 1 to not correspond one-to-one with the second clip 9 and the second insert 10 on the second PVC board 2, thus causing installation errors.

[0028] The PVC mesh frame 5 between the rock wool fireproof core material 4 and the EPDM rubber sheet 6 creates a static air layer between them for heat insulation. This mesh frame 5 also enhances the overall strength of the insulation board. Furthermore, the modified EPDM rubber sheet 6 improves its flame retardancy, allowing it to work in conjunction with the rock wool fireproof core material 4 to form a fireproof and heat-insulating core material, thus improving fire resistance.

[0029] The fixing assembly includes two pairs of first clamping plates 7 and first inserting plates 8 fixedly installed on the side of the first PVC board 1 near the second PVC board 2, and two pairs of second clamping plates 9 and second inserting plates 10 fixedly installed on the side of the second PVC board 2 near the first PVC board 1. One pair of first clamping plates 7 and first inserting plates 8 is fixedly connected to a set of opposite edges on the side of the first PVC board 1 near the second PVC board 2, and the other pair of first clamping plates 7 and first inserting plates 8 is fixedly installed on another set of opposite edges on the side of the first PVC board 1 near the second PVC board 2. Similarly, one pair of second clamping plates 9 and second inserting plates 10 is fixedly installed on a set of opposite edges on the side of the second PVC board 2 near the first PVC board 1, and the other pair of second clamping plates 9 and second inserting plates 10 is fixedly installed on another set of opposite edges on the side of the second PVC board 2 near the first PVC board 1. First weakening grooves 11 are formed on both sides of the first clamping plates 7 and second clamping plates 9, and second weakening grooves 12 are formed on one side of the first inserting plates 8 and second inserting plates 10. The first card plate 7 and the second card plate 9 each have multiple first card slots 13 and second card slots 14 inside. The multiple first card slots 13 and second card slots 14 are arranged in a non-equidistant linear array inside the corresponding first card plate 7 and the second card plate 9. The first insert plate 8 and the second insert plate 10 each have a first card block 15 and a second card block 16 fixedly installed on their opposite sides. The number and position of the first card blocks 15 and the second card blocks 16 correspond one-to-one with the first card slots 13 and the second card slots 14 on the first card plate 7 and the second card plate 9. The inner contour of the first card slot 13 matches the outer contour of the first card block 15, and the inner contour of the second card slot 14 matches the outer contour of the second card block 16. The outer walls of the first card blocks 15 and the second card blocks 16 have guide rounded corners 17. The guide rounded corners 17 are used to assist the first card plate 7 and the second card plate 9 in pressing open the first insert plate 8 and the second insert plate 10, so that the first card slots 13 and the second card slots 14 can be engaged with the corresponding first card blocks 15 and the second card blocks 16.

[0030] The installation of insulation boards to walls is existing technology, so it will not be described in detail.

[0031] Specifically, by setting the first slot 13 and second slot 14 on the first card plate 7 and the second card plate 9, and the first card block 15 and second card block 16 on the first insert plate 8 and the second insert plate 10 in a non-equidistant linear array, after the first card plate 7 and the second card plate 9 on one insulation board are completely aligned with the first insert plate 8 and the second insert plate 10 on the other insulation board, the first card block 15 and the second card block 16 on the first insert plate 8 and the second insert plate 10 can correspond to and be inserted into the first slot 13 and the second slot 14 on the first card plate 7 and the second card plate 9, thus snapping the two insulation boards together and supporting and fixing multiple insulation boards to each other, improving the overall stability of the insulation boards after installation, preventing the insulation boards from detaching from the wall, and avoiding errors in the docking and fixing of the two insulation boards, which would require workers to re-dock and fix them. At the same time, after the first card plate 7 and the second card plate 9 on the two insulation boards dock with the first insert plate 8 and the second insert plate 10, a "V" shaped sealing surface can be formed between the two insulation boards, improving the sealing performance of the insulation board connection.

[0032] With the first weakening groove 11 on the first card plate 7 and the second card plate 9, when the last insulation board in a row is installed indoors, the first card plate 7 and the second card plate 9 of the insulation board near the corner of the wall can be squeezed and deformed by the adjacent wall. The first card plate 7 deforms first and enters between the first PVC board 1 and the second PVC board 2 of the insulation board, and then the second card plate 9 enters between the first PVC board 1 and the second PVC board 2 of the insulation board. The restoring force of the first card plate 7 and the second card plate 9 can apply pressure to the entire row of insulation boards, increase the sealing pressure at the joint of the entire row of insulation boards, and further improve the sealing performance at the joint of the entire row of insulation boards. At the same time, it increases the sealing at the joint between the insulation board and the adjacent wall at the corner, and prevents the first card plate 7 and the second card plate 9 of the insulation board from being unable to bend inward, resulting in gaps at the adjacent wall position at the corner.

[0033] When installing the second row of insulation boards after the first row is installed, the bottom and side of each insulation board need to align with the second row. To achieve this, the second row can be staggered, causing the first retaining plate 7, second retaining plate 9, and first insert plate 8, second insert plate 10 at the contact points to press against each other. This prevents the first retaining groove 13, second retaining groove 14, and first retaining block 15, second retaining block 16 from being inserted together. The first retaining plate 7 and second retaining plate 9, through the first retaining block 15 and second retaining block 16, then deform the first insert plate 8 and second insert plate 10. Then push the insulation board to move towards the side insulation board, so that the first clamping plate 7 and the second clamping plate 9 slide along the outer wall of the first clamping block 15 and the second clamping block 16 until they stop after docking with the side insulation board. At this time, they are aligned with the lower insulation board, so that the first clamping slot 13 and the second clamping slot 14 on the first clamping plate 7 and the second clamping plate 9 can be inserted into the corresponding first clamping block 15 and the second clamping block 16 on the first inserting plate 8 and the second inserting plate 10. At this time, the insulation board is locked and fixed in the lower direction and the side direction, so that the insulation board will not get stuck when docking with the insulation board in multiple directions at the same time.

[0034] The mounting assembly includes multiple first elastic strips 18 fixedly connected to the connecting block 3 of the first PVC board 1 near the side of the second PVC board 2. The multiple first elastic strips 18 are arranged in a circumferential array. Triangular blocks 19 are fixedly connected to the outer walls of the multiple first elastic strips 18. The connecting block 3 of the second PVC board 2 has a first circular hole 20 inside, and the second PVC board 2 has a second circular hole 21 inside. The inner contour of the first circular hole 20 is smaller than the inner contour of the second circular hole 21, and the first circular hole 20 and the second circular hole 21 are connected. The first elastic strips 18 are inserted into the first circular hole 20, and the triangular blocks 19 are inserted into the second circular hole 21. A circular plate 22 is inserted between the multiple triangular blocks 19. Multiple second elastic strips 23 are fixedly connected to the side of the circular plate 22 away from the first PVC board 1 in a circumferential array. The multiple second elastic strips 23 are fixedly installed on the inner wall of the second circular hole 21.

[0035] During the production and assembly of the insulation board, the rock wool fireproof core material 4, PVC mesh frame 5, and EPDM rubber sheet 6 can be placed sequentially on the second PVC board 2. The first PVC board 1 is then aligned with the second PVC board 2 and pressed down, causing the first elastic strip 18 and triangular locking blocks 19 on the connecting block 3 of the first PVC board 1 to insert into the first round hole 20 inside the connecting block 3 of the second PVC board 2. During this process, multiple triangular locking blocks 19 are guided and squeezed by the first round hole 20, causing the multiple triangular locking blocks 19 to move closer to each other. This causes the first elastic strip 18 to deform and accumulate force until the overall outer contour formed by the multiple triangular blocks 19 is smaller than the inner contour of the first circular hole 20, at which point the triangular blocks 19 and the first elastic strip 18 will enter the interior of the first circular hole 20. As the triangular blocks 19 continue to move, they begin to enter the interior of the second circular hole 21 of the second PVC plate 2 and push the circular plate 22, causing the circular plate 22 to move together with the triangular blocks 19 and compress the second elastic strip 23 to deform and accumulate force until the triangular blocks 19 completely disengage from the first circular hole 20. After the triangular locking block 19 is pushed back to its original position by the first elastic bar 18, the circular plate 22 loses its push after the triangular locking block 19 is reset. The second elastic bar 23 then pushes the circular plate 22 to reset. At this time, the circular plate 22 will be inserted between multiple triangular locking blocks 19, limiting and fixing the multiple triangular locking blocks 19 so that they cannot get close to each other and deform. The triangular locking blocks 19 are fixed inside the second circular hole 21. At this time, the first PVC board 1 and the second PVC board 2 are fixed and will not separate, so as to achieve the effect of locking the first PVC board 1 and the second PVC board 2, avoiding the insulation board from separating during use and affecting the normal use of the insulation board. At the same time, through the assembly of the insulation board, the thickness and composition of the insulation layer formed by the internal rock wool fireproof core material 4, PVC mesh frame 5 and EPDM rubber board 6 can be changed according to the needs during use to adapt to different insulation requirements. At the same time, through the multi-layer assembly of the insulation board, after the insulation board is discarded and removed from the wall, the insulation board can be disassembled layer by layer for classified recycling.

[0036] Working principle: When installing multiple insulation boards, first fix one insulation board to the wall as a reference, then align another insulation board with and insert it into the reference insulation board, so that the two insulation boards are snapped together by the fixing components, so that multiple insulation boards support and fix each other, improving the overall stability of the insulation boards after installation and preventing the insulation boards from detaching from the wall.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
