Description

Technical Field

[0001] This application belongs to the technical field of external wall insulation, specifically relating to a prefabricated insulation board for heat insulation and noise reduction. Background Technology

[0002] With the promotion and application of energy-efficient buildings, insulation boards are typically installed on the exterior walls of modern residential buildings to reduce heat transfer between indoors and outdoors, achieving insulation in winter and heat insulation in summer. This reduces energy consumption of air conditioning and heating systems, thereby saving energy costs. As society progresses and people's living standards improve, there are higher requirements for sound insulation in buildings, leading to the development of insulation boards with both thermal insulation and noise reduction functions.

[0003] In related technologies, such as Chinese utility model patent CN222771651U, a novel noise-reducing insulation board is disclosed. This board includes an insulation board with mating plates fixedly connected to both sides. The mating plates have mating grooves fixedly formed inside. A positioning slot is fixedly formed on the back of the insulation board. A limit groove is formed at the upper end of the positioning slot, and a locking groove is formed inside the positioning slot. A locking element is slidably fitted inside the locking groove. The insulation board includes a flame-retardant layer, a heat insulation layer, a reinforcing core, a sound insulation layer, and a protective layer. When installing this novel noise-reducing insulation board, the locking element needs to be pre-embedded inside the wall according to pre-determined dimensions. When the insulation board needs to be installed… The locking component is inserted into the positioning slot for positioning. After positioning, the insulation board is released, and under the action of gravity, the locking component slides through the limiting slide groove into the locking groove for limiting and locking. Since the locking component needs to be pre-embedded in the wall during construction, it increases the difficulty of wall construction. If the construction workers forget to pre-embed the locking component in the wall, the insulation board cannot be installed and fixed. Therefore, the installation of the insulation board depends on the locking component pre-embedded in the wall. In addition, since each insulation board requires multiple locking components, the distance between adjacent locking components is difficult to determine when pre-embedding them, which in turn makes the installation of the insulation board more difficult. Utility Model Content

[0004] This application provides a prefabricated insulation board for heat preservation and noise reduction, so as to reduce the difficulty of installing the insulation board and improve the installation efficiency of the insulation board.

[0005] The technical solution adopted in this application is as follows:

[0006] A prefabricated insulation board for thermal insulation and noise reduction, comprising:

[0007] The insulation board body includes a flame-retardant and heat-insulating layer and a sound-insulating layer disposed on the outside of the flame-retardant and heat-insulating layer;

[0008] Decorative panel, the decorative panel being disposed on the outer side of the sound insulation layer;

[0009] The fixing frame includes a fixing plate, limiting plates disposed on opposite sides of the fixing plate, and a stop plate disposed on the limiting plates. The fixing plate is located inside the insulation board body, the limiting plates are located on both sides of the insulation board body and the decorative panel, and the stop plate is located outside the decorative panel and can stop the decorative panel in the outward direction.

[0010] By adopting the above technical solution, when installing the prefabricated insulation board in this application, the fixing frame is first fixedly connected to the outer wall by expansion nails, and then when installing the insulation board body and the decorative panel, the insulation board body and the decorative panel are inserted between the two limiting pieces, and the decorative panel is located inside the stop piece, so as to complete the installation of the prefabricated insulation board.

[0011] After the prefabricated insulation board is installed, the stop plate is located on the outside of the decorative panel and can stop the decorative panel in the outward direction, thereby increasing the stability of the decorative panel and the insulation board itself, and thus ensuring the fixing effect of the prefabricated insulation board. Furthermore, the prefabricated insulation board in this application does not require pre-embedded locking components in the wall, thus avoiding the increased difficulty of exterior wall construction due to the need for pre-embedded locking components in the exterior wall. It also avoids the situation where the insulation board cannot be installed on the exterior wall due to deviations between the pre-embedded locking components and the actual required position, thereby reducing the installation difficulty of the prefabricated insulation board and improving its installation efficiency.

[0012] Furthermore, since existing building construction basically adopts a concrete frame structure, and then fills the frame with aerated concrete blocks, the locking components of the technical solutions mentioned in the background art can only be pre-embedded in the concrete frame structure. This means that the locking components cannot be pre-embedded in the position of the aerated concrete blocks, and therefore the insulation board cannot be fixed in the position of the aerated concrete blocks. However, the technical solution in this application uses expansion nails to fix the fixing frame to the external wall, so that the installation position of the fixing frame is no longer restricted by the external wall structure, thereby improving the flexibility of the prefabricated insulation board.

[0013] Optionally, the fixing frame further includes a support piece located at the bottom of the insulation board body and the decorative board, with both ends of the support piece connected to the limiting piece.

[0014] By adopting the above technical solution, when installing the prefabricated insulation board in this application, expansion nails are first used to fix the fixing frame to the exterior wall, while the support plate is located at the bottom of the limiting plate. Then, when installing the insulation board body and decorative panel in the direction from top to bottom, the insulation board body and decorative panel move in the direction from top to bottom to between the stop plate and the fixing plate, so that the bottom of the insulation board body and decorative panel abuts against the support plate, thereby using the support plate to support the insulation board body and decorative panel, thereby improving the stability of the insulation board and decorative panel, and thus improving the fixing effect of the prefabricated insulation board.

[0015] Optionally, the stop piece is bent inward on the side away from the limiting piece to form an edge, and a snap-fit ​​space is formed between the edge and the limiting piece. The decorative panel is provided with a snap-fit ​​section located in the snap-fit ​​space.

[0016] By adopting the above technical solution, after the decorative panel and the insulation board body are installed between the two limiting pieces, the snap-fit ​​section of the decorative panel is located in the snap-fit ​​space formed by the edge and the limiting piece, so as to limit the decorative panel and the insulation board body by using the mutual restraint between the snap-fit ​​section and the edge, thereby increasing the fixing stability of the decorative panel and the insulation board body.

[0017] Optionally, the decorative panel has inwardly bent sections on opposite sides, the bent sections having folded sections extending toward the direction of the limiting piece, and the snap-fit ​​section is located on the folded sections.

[0018] By adopting the above technical solution, since the decorative panel has inwardly bent sections on both sides, and the bent sections have folded sections extending in the direction of the limiting piece, and the snap-fit ​​section is located on the folded section, the folded section is recessed into the end face of the decorative panel away from the insulation board body. This allows the end face of the decorative panel away from the insulation board body to be flush with the stop piece after the decorative panel and the insulation board body are installed on the exterior wall, thereby improving the appearance quality of the prefabricated insulation board and avoiding the situation where there is a step difference between the decorative panel and the stop piece, which would affect the user's tactile feel, thus improving the user's tactile feel.

[0019] Optionally, the projection of the fixing piece toward the stop piece has an overlapping area that coincides with the stop piece and a non-overlapping area located inside the overlapping area, wherein the non-overlapping area is provided with a through hole for the expansion pin to pass through.

[0020] By adopting the above technical solution, since the non-critical area is provided with through holes for the expansion nails to pass through, the expansion nails and the stop plates can be made to avoid each other when the expansion nails are installed, thereby reducing the difficulty of installing the expansion nails and improving the installation efficiency of the prefabricated insulation board.

[0021] Optionally, each of the two limiting plates has a sealing groove on the side opposite to the insulation board body, and a sealing gasket is provided in one of the sealing grooves, the thickness of which is equal to twice the depth of the sealing groove.

[0022] By adopting the above technical solution, since a sealing gasket is provided in one of the sealing grooves and the thickness of the sealing gasket is equal to twice the depth of the sealing groove, after the two fixing frames are spliced ​​together, the sealing gasket on one fixing frame can extend into the sealing groove on the other fixing frame and abut against the groove wall of the sealing groove, thereby increasing the sealing between the two adjacent fixing frames and ensuring the insulation effect of the prefabricated insulation board on the exterior wall.

[0023] Optionally, the flame-retardant and heat-insulating layer has an inner end face that is opposite to the sound-insulating layer, and the inner end face is provided with a plurality of adhesive grooves extending in the vertical direction.

[0024] By adopting the above technical solution, since the inner end face is provided with multiple adhesive grooves extending in the vertical direction, after the prefabricated insulation board is installed on the exterior wall, adhesive can be poured into the adhesive grooves to fix the insulation board body again with the adhesive, thereby further improving the fixing effect of the prefabricated insulation board.

[0025] Optionally, the inner end face is provided with a receiving notch, and the fixing piece is located in the receiving notch.

[0026] By adopting the above technical solution, since the inner end face is provided with a receiving notch and the fixing piece is located in the receiving notch, after the prefabricated insulation board is installed on the exterior wall, the inner end face of the flame-retardant insulation layer can abut against the exterior wall. On the one hand, this can increase the stability of the insulation board itself, and on the other hand, it can increase the insulation effect of the prefabricated insulation board on the exterior wall.

[0027] Optionally, the decorative panel is provided with a fixing arm that passes through the flame-retardant heat insulation layer and the sound insulation layer, and the fixing arm has a stop section that cooperates with the stop of the flame-retardant heat insulation layer.

[0028] By adopting the above technical solution, since the decorative panel is provided with a fixing arm that passes through the flame-retardant heat insulation layer and the sound insulation layer, and the fixing arm has a stop section that cooperates with the stop of the flame-retardant heat insulation layer, the decorative panel and the insulation board body can be fixedly connected together by the fixing arm, so as to increase the stability of the prefabricated insulation board and reduce the assembly difficulty of the prefabricated insulation board.

[0029] Optionally, the flame-retardant and heat-insulating layer has an inner end face that is opposite to the sound-insulating layer, the inner end face is provided with a hidden cavity, the stop section is located in the hidden cavity, and the thickness of the stop section is less than the depth of the hidden cavity.

[0030] By adopting the above technical solution, since the stop section is located in the hidden cavity and the thickness of the stop section is less than the depth of the hidden cavity, the stop section can be hidden in the hidden cavity, so as to ensure that after the prefabricated insulation board is installed on the exterior wall, the flame-retardant heat insulation layer can contact the exterior wall, thereby increasing the stability of the prefabricated insulation board.

[0031] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0032] 1. The prefabricated insulation board in this application includes an insulation board body, a decorative panel, and a fixing frame. The insulation board body includes a flame-retardant and heat-insulating layer and a sound-insulating layer disposed on the outside of the flame-retardant and heat-insulating layer. The decorative panel is disposed on the outside of the sound-insulating layer. The fixing frame includes a fixing plate, limiting plates disposed on opposite sides of the fixing plate, and a stop plate disposed on the limiting plate. The fixing plate is located on the inner side of the insulation board body, the limiting plates are located on both sides of the insulation board body and the decorative panel, and the stop plate is located on the outer side of the decorative panel and can stop the decorative panel in the outward direction. The prefabricated insulation board in this application does not require pre-embedded locking components in the wall, thereby avoiding the situation where the difficulty of exterior wall construction is increased due to the need to pre-embed locking components in the exterior wall. At the same time, it avoids the situation where the insulation board cannot be installed on the exterior wall due to the deviation between the pre-embedded locking components in the exterior wall and the actual required position. This reduces the installation difficulty of the prefabricated insulation board and improves the installation efficiency of the prefabricated insulation board.

[0033] 2. The fixing frame in this application also includes a support plate located at the bottom of the insulation board body and the decorative panel. The two ends of the support plate are connected to the limiting plate. When installing the prefabricated insulation board in this application, the fixing frame is first fixed to the exterior wall using expansion nails, while the support plate is located at the bottom of the limiting plate. Then, when installing the insulation board body and the decorative panel in the direction from top to bottom, the insulation board body and the decorative panel move in the direction from top to bottom to between the stop plate and the fixing plate, so that the bottom of the insulation board body and the decorative panel abuts against the support plate, thereby using the support plate to support the insulation board body and the decorative panel, thereby improving the stability of the insulation board and the decorative panel, and thus improving the fixing effect of the prefabricated insulation board.

[0034] 3. In this application, the stop piece is bent inward on the side away from the limiting piece to form an edge, and a snap-fit ​​space is formed between the edge and the limiting piece. The decorative panel is provided with a snap-fit ​​section located in the snap-fit ​​space. After the decorative panel and the insulation board body are installed between the two limiting pieces, the snap-fit ​​section of the decorative panel is located in the snap-fit ​​space formed by the edge and the limiting piece, so as to limit the decorative panel and the insulation board body by the mutual restraint of the snap-fit ​​section and the edge, thereby increasing the fixing stability of the decorative panel and the insulation board body.

[0048] Reference Figures 1 to 5 A prefabricated insulation board for heat preservation and noise reduction is disclosed, which includes an insulation board body 1, a decorative panel 2, and a fixing frame 3. The insulation board body 1 includes a flame-retardant heat insulation layer 11 and a sound insulation layer 12 disposed on the outside of the flame-retardant heat insulation layer 11. The decorative panel 2 is disposed on the outside of the sound insulation layer 12. The fixing frame 3 includes a fixing piece 31, a limiting piece 32 disposed on opposite sides of the fixing piece 31, and a stop piece 33 disposed on the limiting piece 32. The fixing piece 31 is located on the inner side of the insulation board body 1, the limiting piece 32 is located on both sides of the insulation board body 1 and the decorative panel 2, and the stop piece 33 is located on the outer side of the decorative panel 2 and can stop the decorative panel 2 in the outward direction.

[0049] It should be noted that, in this application, the outer side of the flame-retardant and heat-insulating layer 11 refers to the side of the flame-retardant and heat-insulating layer 11 that is away from the exterior wall, while the inner side of the flame-retardant and heat-insulating layer 11 refers to the side of the flame-retardant and heat-insulating layer 11 that faces the exterior wall; the outer side of the sound insulation layer 12 refers to the side of the sound insulation layer 12 that is away from the flame-retardant and heat-insulating layer 11, while the inner side of the sound insulation layer 12 refers to the side of the sound insulation layer 12 that faces the flame-retardant and heat-insulating layer 11.

[0050] It is understandable that there are two limiting pieces 32, and the two limiting pieces 32 are located on opposite sides of the fixing piece 31, and a stop piece 33 is provided on the side of the two limiting pieces 32 that are close to each other.

[0051] When installing the prefabricated insulation board in this application, the fixing frame 3 is first fixedly connected to the outer wall by expansion nails. Then, when installing the insulation board body 1 and the decorative panel 2, the insulation board body 1 and the decorative panel 2 are inserted between the two limiting pieces 32, and the decorative panel 2 is located inside the stop piece 33 to complete the installation of the prefabricated insulation board.

[0052] Specifically, when using expansion nails to install the mounting bracket 3 on the exterior wall, first use an impact drill to make a hole in the exterior wall, then pass the head of the expansion nail through the fixing piece 31 and into the hole in the exterior wall, and then tighten the screw of the expansion nail. This will allow the mounting bracket 3 to be fixedly installed on the exterior wall using expansion nails.

[0053] After the prefabricated insulation board is installed, the stop plate 33 is located on the outside of the decorative panel 2 and can stop the decorative panel 2 in the outward direction, thereby increasing the stability of the decorative panel 2 and the insulation board body 1, and thus ensuring the fixing effect of the prefabricated insulation board. Furthermore, the prefabricated insulation board in this application does not require pre-embedded locking components in the wall, thus avoiding the increased difficulty of exterior wall construction due to the need for pre-embedded locking components. It also avoids the situation where the insulation board cannot be installed on the exterior wall due to deviations between the pre-embedded locking components and the actual required position, thereby reducing the installation difficulty of the prefabricated insulation board and improving its installation efficiency. Moreover, the prefabricated insulation board in this application avoids the need for locking components during installation, thus improving the flexibility of prefabricated insulation board installation.

[0054] Furthermore, since existing building construction basically adopts a concrete frame structure, and then fills the concrete frame structure with aerated concrete blocks, the locking components of the technical solutions mentioned in the background art can only be pre-embedded in the concrete frame structure. This means that the locking components cannot be pre-embedded in the position of the aerated concrete blocks, and therefore the insulation board cannot be fixed in the position of the aerated concrete blocks. However, the technical solution in this application uses expansion nails to fix the fixing frame 3 to the external wall, so that the installation position of the fixing frame 3 is no longer restricted by the external wall structure, thereby improving the flexibility of the prefabricated insulation board.

[0055] Furthermore, since the insulation board body 1 includes a flame-retardant heat insulation layer 11 and a sound insulation layer 12, the prefabricated insulation board of this application, when installed on the exterior wall, not only is the heat insulation performance of the exterior wall improved, but also the sound insulation and noise reduction performance of the exterior wall is improved.

[0056] This application does not specifically limit the flame-retardant and heat-insulating layer 11, which can be a structure composed of a board material with heat-insulating and flame-retardant properties, such as polystyrene foam board, extruded polystyrene foam board, or foamed cement board.

[0057] This application does not specifically limit the sound insulation layer 12, which can be a structure made of sound-insulating materials such as high-density fiberboard, polyester fiberboard, glass wool board or rock wool board.

[0058] In a preferred embodiment, refer to Figure 2 and Figure 3 The fixing frame 3 also includes a support piece 34 located at the bottom of the insulation board body 1 and the decorative board 2, with both ends of the support piece 34 connected to the limiting piece 32.

[0059] When installing the prefabricated insulation board in this application, the fixing bracket 3 is first fixed to the exterior wall using expansion nails, while the support plate 34 is located at the bottom of the limiting plate 32. Then, when installing the insulation board body 1 and the decorative plate 2 in the direction from top to bottom, the insulation board body 1 and the decorative plate 2 move in the direction from top to bottom to between the stop plate 33 and the fixing plate 31, so that the bottom of the insulation board body 1 and the decorative plate 2 abuts against the support plate 34, so as to use the support plate 34 to support the insulation board body 1 and the decorative plate 2, thereby improving the stability of the insulation board and the decorative plate 2, and thus improving the fixing effect of the prefabricated insulation board.

[0060] Of course, in addition to the support plate 34 mentioned above being located at the bottom of the insulation board body 1 and the decorative panel 2, the support plate 34 can also be located on one side of the insulation board body 1 and the decorative panel 2 in the left and right directions, so that the support plate 34 limits the insulation board body 1 and the decorative panel 2 in the left and right directions, and the insulation board body 1 and the decorative panel 2 need to be installed in the left and right directions when installing the insulation board body 1 and the decorative panel 2.

[0061] In a preferred embodiment, refer to Figures 2 to 5 The side of the stop plate 33 away from the limiting plate 32 is bent inward to form an edge 331, and a snap-fit ​​space 332 is formed between the edge 331 and the limiting plate 32. The decorative panel 2 is provided with a snap-fit ​​section 21 located in the snap-fit ​​space 332.

[0062] After the decorative panel 2 and the insulation board body 1 are installed between the two limiting pieces 32, the snap-fit ​​section 21 of the decorative panel 2 is located in the snap-fit ​​space 332 formed by the edge 331 and the limiting piece 32, so as to limit the decorative panel 2 and the insulation board body 1 by the mutual binding of the snap-fit ​​section 21 and the edge 331, thereby increasing the fixing stability of the decorative panel 2 and the insulation board body 1.

[0063] Furthermore, refer to Figures 2 to 5 The decorative panel 2 has inwardly bent sections 22 on opposite sides, and the bent sections 22 have folded sections 23 extending toward the direction of the limiting piece 32. The snap-fit ​​section 21 is provided on the folded section 23.

[0064] Because the decorative panel 2 has inwardly bent sections 22 on both sides, and the bent sections 22 have folded sections 23 extending in the direction of the limiting piece 32, and the snap-fit ​​section 21 is provided on the folded sections 23, the folded sections 23 are recessed in the end face of the decorative panel 2 away from the insulation board body 1, so that after the decorative panel 2 and the insulation board body 1 are installed on the exterior wall, the end face of the decorative panel 2 away from the insulation board body 1 can be flush with the stop piece 33, thereby improving the appearance quality of the prefabricated insulation board, and avoiding the situation where there is a step difference between the decorative panel 2 and the stop piece, which would affect the user's touch feel, thus improving the user's touch feel.

[0065] Preferably, the edge of the sound insulation layer 12 is provided with a notch for accommodating the folded section 23 and the bent section 22, so that the end face of the decorative panel 2 facing the sound insulation layer 12 can abut against the sound insulation layer 12, thereby increasing the stability of the decorative panel 2.

[0066] In a preferred embodiment, refer to Figure 2 and Figure 3 The projection of the fixing piece 31 toward the stop piece 33 has an overlapping area that coincides with the stop piece 33 and a non-overlapping area located inside the overlapping area. The non-overlapping area is provided with a through hole 311 for the expansion nail to pass through. Thus, when the expansion nail is installed, the expansion nail and the stop piece 33 can be made to avoid each other, thereby reducing the difficulty of installing the expansion nail and improving the installation efficiency of the prefabricated insulation board.

[0067] It is understandable that the non-weighted area is located inside the stop plate 33 on the projection of the fixed plate 31 toward the stop plate 33. In other words, the non-weighted area does not coincide with the stop plate 33 on the projection of the fixed plate 31 toward the stop plate 33.

[0068] Preferably, multiple through holes 311 are provided at circumferential intervals along the overlapping area to increase the number of fixing points for the fixing frame 3 using expansion nails, thereby improving the fixing stability of the prefabricated insulation board.

[0069] In a preferred embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 Both limiting plates 32 are provided with sealing grooves 321 on the side away from the insulation board body 1. A sealing gasket 322 is provided in one of the sealing grooves 321. The thickness of the sealing gasket 322 is equal to twice the depth of the sealing groove 321.

[0070] Since a sealing gasket 322 is provided in one of the sealing grooves 321, and the thickness of the sealing gasket 322 is equal to twice the depth of the sealing groove 321, after the two fixing frames 3 are spliced ​​together, the sealing gasket 322 on one fixing frame 3 can extend into the sealing groove 321 on the other fixing frame 3 and abut against the groove wall of the sealing groove 321, so as to increase the sealing between the two adjacent fixing frames 3, thereby ensuring the thermal insulation and noise reduction effect of the prefabricated insulation board on the exterior wall.

[0071] This application does not specifically limit the formation method of the sealing groove 321. Preferably, the end face of the limiting piece 32 facing away from the insulation board body 1 is recessed into the ends of the stop piece 33 and the fixing piece 31, so that the stop piece 33, the limiting piece 32, and the fixing piece 31 together form the sealing groove 321. In other embodiments, the sealing groove 321 may also be a groove-shaped structure formed in the limiting piece 32.

[0072] In a preferred embodiment, refer to Figure 1 and Figure 4 The flame-retardant and heat-insulating layer 11 has an inner end face that is opposite to the sound insulation layer 12, and the inner end face is provided with a plurality of adhesive grooves 111 extending in the vertical direction.

[0073] Since the inner end face is provided with multiple adhesive grooves 111 extending in the vertical direction, after the prefabricated insulation board is installed on the exterior wall, adhesive can be poured into the adhesive grooves 111 to fix the insulation board body 1 again with the adhesive, so as to further improve the fixing effect of the prefabricated insulation board.

[0074] Furthermore, the end face of the fixing piece 31 is U-shaped, and the inner end face is provided with a receiving notch, with the fixing piece 31 located at the receiving notch.

[0075] Because the inner end face is provided with a receiving notch, the fixing piece 31 is located in the receiving notch. After the prefabricated insulation board is installed on the exterior wall, the inner end face of the flame-retardant insulation layer 11 can abut against the exterior wall. On the one hand, this can increase the stability of the insulation board body 1, and on the other hand, it can increase the insulation effect of the prefabricated insulation board on the exterior wall.

[0076] This application does not specify the connection method between the decorative panel 2 and the insulation board body 1. Preferably, refer to... Figure 4 The decorative panel 2 is provided with a fixing arm 24 that passes through the flame-retardant heat insulation layer 11 and the sound insulation layer 12. The fixing arm 24 has a stop section 241 that cooperates with the stop of the flame-retardant heat insulation layer 11.

[0077] Since the decorative panel 2 is provided with a fixing arm 24 that passes through the flame-retardant heat insulation layer 11 and the sound insulation layer 12, and the fixing arm 24 has a stop section 241 that cooperates with the stop of the flame-retardant heat insulation layer 11, the decorative panel 2 and the insulation board body 1 can be fixedly connected together by the fixing arm 24, so as to increase the stability of the prefabricated insulation board and reduce the assembly difficulty of the prefabricated insulation board.
