Description

Technical Field

[0001] This utility model relates to the field of construction, specifically to a spliced ​​aerogel composite panel. Background Technology

[0002] To improve living comfort, air conditioning is typically used for cooling in summer and air conditioning or heating for heating in winter. In this context, building insulation reduces heat transfer between the indoor and outdoor environments, allowing for the maintenance of comfortable indoor temperatures with less energy. Traditional insulation involves coating the interior walls of buildings with insulating mortar. However, insulating mortar is dense, highly hygroscopic, and prone to excessive weight and detachment. Furthermore, the insulation performance of traditional mortar is insufficient to meet increasingly demanding requirements. Therefore, insulation boards are now commonly used instead of traditional insulating mortar.

[0003] Current insulation boards, such as the one disclosed in patent number CN202010258749.1, include a first panel layer, a second panel layer, a core layer, and a skeleton support layer. The core layer is a single aerogel felt layer or composed of two or more layers of aerogel felt stacked together. Each aerogel felt layer is composed of several fiber-reinforced aerogel composite felts spliced ​​together. The core layer is located between the first panel layer and the second panel layer. The skeleton support layer is integrally formed and filled in the lower surface of the core layer and between the first panel layer, the upper surface of the core layer and between the second panel layer, the four edges of the core layer, and the seams between any two adjacent fiber-reinforced aerogel composite felts in the core layer. The skeleton support layer is integrally formed with the first panel layer and the second panel layer. The first panel layer, the second panel layer, and the skeleton support layer are all fiber-reinforced resin.

[0004] Aerogel felt has a lower thermal conductivity and better insulation performance than thermal insulation mortar. The skeleton support layer supports the first and second panel layers to ensure sufficient strength of the composite board. However, during use, heat is transferred through the skeleton support layer, causing heat to be quickly transferred from the interior to the exterior or vice versa. This results in limited insulation performance and makes it unsuitable for public buildings with large windows. Utility Model Content

[0005] The present invention aims to provide a spliced ​​aerogel composite panel to further improve the thermal insulation effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spliced ​​aerogel composite board, comprising a first board body and a second board body, the first board body and the second board body facing each other, forming a heat insulation cavity between the first board body and the second board body, and the heat insulation cavity is filled with aerogel felt, the side wall of the first board body facing the heat insulation cavity has a plurality of first support blocks, the side wall of the second board body facing the heat insulation cavity has a plurality of second support blocks fixed thereon, the first support blocks and the second support blocks are alternately distributed in the heat insulation cavity, and there are gaps between the first support blocks and the second board body and between the second support blocks and the first board body; a plurality of positioning members are fixed on the first board body, the positioning members extend into the heat insulation cavity and are fixed to the second support blocks; the side of the heat insulation cavity is provided with a sealing layer.

[0007] The beneficial effects of this plan are: 1. The insulation cavity in this design consists of a first plate and a second plate, which are separated from each other. There is a gap between the first support block on the first plate and the second plate, and a gap between the second support block on the second plate and the first plate. When the aerogel felt is filled into the insulation cavity, it will fill the gaps simultaneously, so that neither the first plate nor the first support block is in direct contact with the second plate or the second support block. Heat cannot be directly transferred between the first plate and the second plate through the first and second support blocks. Therefore, the heat in this design is hindered by the aerogel felt, which effectively improves the insulation effect and is more suitable for use in public buildings with large windows.

[0008] 2. In this design, the first and second panels are separate, and the insulation cavity is formed by splicing the first and second panels. Therefore, the first and second panels can be processed and shaped separately, resulting in lower processing difficulty and higher efficiency. Compared with directly processing the insulation cavity within a single, complete panel, the processing of the first and second panels in this design is more convenient.

[0009] 3. In this design, the first and second support blocks are embedded within the aerogel felt when it is filled into the insulation cavity, providing support and effectively improving its strength. The positioning element in this design fixes the first plate to the second support block, and the second support block to the second plate. Therefore, the positioning element supports both the first and second plates to maintain the shape of the insulation cavity, while simultaneously connecting the first plate, aerogel felt, and second plate into a single unit, further enhancing the strength of the insulation cavity.

[0010] Furthermore, several U-shaped plates are fixed to the side wall of the second plate away from the insulation cavity. The U-shaped plates extend vertically and form an installation cavity between the U-shaped plates and the second plate. Aerogel felt is also provided in the installation cavity.

[0011] The beneficial effects of this solution are as follows: the U-shaped plate in this solution serves a decorative purpose, and the aerogel felt filled in the installation cavity also provides insulation, thereby further improving the insulation effect of the insulation board.

[0012] Furthermore, the cross-sections of the end of the first support block away from the first plate and the end of the second support block away from the second plate are both arc-shaped.

[0013] The beneficial effects of this solution are as follows: when installing the positioning component, if the positioning component is slightly tilted, the positioning component will be slightly offset from the center of the end of the second support block that is directly opposite the first plate after it is inserted into the second support block. The arc shape in this solution ensures that the end of the second support block near the first plate has no side ridges, thus allowing for better insertion of the positioning component.

[0014] Furthermore, the positioning component includes a T-shaped head and a rod, with the head and rod fixed together. The head is located on the side of the first plate away from the insulation cavity, and the rod penetrates the first plate and is inserted into the second support block.

[0015] The beneficial effects of this solution are: when the rod is inserted into the second support block, the head abuts against the first plate, and the positioning component can limit the first plate, thereby better connecting the first plate and the second plate.

[0016] Furthermore, the side wall of the first plate away from the insulation cavity is provided with a receiving groove corresponding to the positioning member, and the head is located in the receiving groove.

[0017] The beneficial effects of this solution are: the receiving groove can prevent the head from protruding outside the first plate, ensuring that the first plate can be attached to the wall when the insulation board is installed.

[0018] Furthermore, the rod portion includes a sleeve, a limiting part, and a fixing part. The sleeve is fixed to the head, the limiting part is fixed to the end of the sleeve away from the head, and the limiting part includes multiple fins distributed circumferentially along the sleeve. The fixing part includes a large-diameter section, a small-diameter section, and an insertion section that are sequentially distributed and fixedly connected. The diameter of the large-diameter section is larger than the diameter of the small-diameter section. The large-diameter section is located inside the sleeve and slides within the sleeve, and the large-diameter section can push the fins away from the large-diameter section. The small-diameter section passes through the limiting part, and the diameter of the insertion section is larger than the outer diameter of the limiting part at the end away from the head but smaller than the outer diameter of the sleeve.

[0019] The beneficial effects of this solution are as follows: the small diameter section can be nailed into the second support block to connect the first plate and the second plate, so that the first plate and the second plate will not separate when subjected to mutual tensile forces, while the large diameter section can abut against the second support block, so that the first plate and the second plate will not move toward each other when subjected to mutual pressure, thus forming a more solid insulation cavity.

[0020] At the same time, when the large-diameter section slides outward relative to the sleeve, it can push the fins, thereby causing the fins to open to the side away from the large-diameter section. After filling with aerogel felt, the opened fins are embedded in the aerogel felt, making it less likely for the first plate to separate from the aerogel felt when the first plate and the second plate are subjected to tension on the side away from the aerogel felt, thereby further improving the integrity of the composite plate.

[0021] Furthermore, the limiting sleeve is provided with a limiting hole for the small diameter section to pass through, and a step is formed between the large diameter section and the small diameter section, and the step abuts against the limiting sleeve.

[0022] The beneficial effects of this solution are: the step can better abut against the limiting sleeve, improving the limiting effect of preventing the first plate and the second plate from approaching each other.

[0023] Furthermore, the head is provided with an insertion hole that communicates with the sleeve, and the diameter of the insertion hole is smaller than the outer diameter of the large diameter section; the positioning component also includes an extension rod, which extends through the insertion hole into the sleeve and can slide relative to the head.

[0024] The advantages of this solution are: the extension rod allows for better protrusion of the fixing part, making installation more convenient.

[0025] Furthermore, a limiting block is fixed at the end of the fin near the insertion section, and a limiting groove is provided at the end of the insertion section opposite to the limiting block, with the limiting block located within the limiting groove.

[0026] The beneficial effects of this solution are: the fins can be positioned by the cooperation of the limiting block and the limiting groove, and the fins will not open when the rod of the positioning part passes through the first plate, ensuring the smooth insertion of the rod.

Detailed Implementation

[0028] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: first plate 1, receiving groove 11, first support plate 12, second plate 2, second support plate 21, U-shaped plate 22, positioning element 3, limiting sleeve 4, limiting hole 41, head 5, insertion hole 51, extension rod 6, sleeve 7, fin 71, fixing part 8, large diameter section 81, small diameter section 82, insertion section 9, and limiting groove 91.

[0029] Example 1 Example 1 is basically as follows Figure 1 As shown, the spliced ​​aerogel composite panel includes a first panel 1 and a second panel 2, which are opposite to each other and form an insulation cavity between them. The left and right sides of the first panel 1 and the second panel 2 are provided with sealing layers. The sealing layers are used to seal the left and right side walls of the insulation cavity. The sealing layers in this embodiment are the same as those in the prior art and will not be described in detail here.

[0030] Combination Figure 2 The first plate 1 has a number of first support blocks on its sidewall facing the insulation cavity, and the second plate 2 has a number of second support blocks fixed on its sidewall facing the insulation cavity. All the first support blocks are arranged in an array, and all the second support blocks are also arranged in an array. Specifically, a row of first support blocks distributed along the height direction of the first plate 1 is the first support group, and a row of second support blocks distributed along the height direction of the second plate 2 is the second support group. The first support group and the second support group are arranged alternately along the width direction of the insulation cavity.

[0031] The first support block is integrally formed with the first plate 1, and there is a gap between the lower end of the first support block and the second plate 2; the second support block is integrally formed with the second plate 2, and there is a gap between the second support block and the first plate 1. In this embodiment, the lower surface of the first support block and the upper surface of the second support block both have arc-shaped cross-sections.

[0032] The first plate 1 is provided with multiple positioning elements 3, each corresponding to a second support block. Each positioning element 3 includes an integrally formed head 5 and a rod, which are arranged in a T-shape. In this embodiment, the positioning elements 3 are fixed nails. The number of positioning elements 3 is less than the number of second support blocks, and each positioning element 3 corresponds to a second support block. The rod of the positioning element 3 passes through the first plate 1 and inserts into the second support block, connecting the first plate 1 and the second plate 2 through the cooperation of the positioning elements 3 and the second support blocks. The top of the first plate 1 is provided with multiple receiving grooves 11, each corresponding to a positioning element 3, with the head 5 of the positioning element 3 located within the receiving groove 11 to prevent the head 5 from protruding above the first plate 1.

[0033] The insulation cavity is filled with aerogel felt. Specifically, the aerogel felt in this embodiment uses existing technology, which will not be described in detail here. During installation, the first panel 1 is attached to the wall, and the second panel 2 faces outwards. In this embodiment, the aerogel felt provides better insulation when the insulation panel is installed.

[0034] Example 2 Based on Example 1, such as Figure 3 , 4 , Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, a plurality of U-shaped plates 22 are fixed to the top of the second plate 2. The U-shaped plates 22 extend along the height direction of the second plate 2. In this embodiment, the U-shaped plates 22 are fixed to the second plate 2 by adhesive or integrally formed with the second plate 2. An installation cavity is formed between the U-shaped plates 22 and the second plate 2, and an aerogel felt is also provided in the installation cavity.

[0035] In this embodiment, the aerogel felt inside the installation cavity can further improve the insulation effect of the insulation board, while also supporting the U-shaped plate 22 to further improve the strength of the insulation board.

[0036] Example 3 Based on Example 1 or 2, such as Figure 3 As shown, the rod in this embodiment includes a sleeve 7, a limiting part, and a fixing part 8. The left end of the sleeve 7 is integrally formed with the head 5. The head 5 is provided with an insertion hole 51 coaxial with the sleeve 7, and the diameter of the insertion hole 51 is smaller than the inner diameter of the sleeve 7. The positioning member 3 is also provided with an extension rod 6, which can extend to the inside of the sleeve 7 through the insertion hole 51 and can slide to the right relative to the head 5 when subjected to a rightward impact.

[0037] The limiting part is located on the right side of the sleeve 7. The limiting part includes six fins 71. The six fins 71 are evenly distributed along the circumference of the sleeve 7, and the right side of the fins 71 extends along the axial direction of the sleeve 7. The left end of the fins 71 is inclined in a direction away from each other and welded to the right end of the sleeve 7, so that the inner diameter of the left end of the limiting part is larger than the inner diameter of the right end.

[0038] The fixing part 8 includes a large-diameter section 81, a small-diameter section 82, and an insertion section 9 distributed sequentially from left to right. In this embodiment, the large-diameter section 81, the small-diameter section 82, and the insertion section 9 are integrally formed. The large-diameter section 81 is located inside the sleeve 7 and can slide relative to the sleeve 7 when subjected to a rightward impact. The diameter of the large-diameter section 81 is larger than the inner diameter of the left end of the limiting part, so that when the large-diameter section 81 slides to the left, it can push the fins 71 in a direction away from each other, causing the fins 71 to deform and open outward away from the large-diameter section 81. The diameter of the large-diameter section 81 is also larger than the diameter of the small-diameter section 82, so that a step is formed between the large-diameter section 81 and the small-diameter section 82.

[0039] The right end of the insertion section 9 forms a pointed tip and is used to penetrate the first plate 1. The diameter of the left end of the insertion section 9 is greater than the diameter of the small diameter section 82 and less than the diameter of the large diameter section 81. The left end of the insertion section 9 is provided with an annular limiting groove 91. The right end of the fin 71 is integrally formed with an arc-shaped limiting block. The projection of the limiting block to the right is located in the limiting groove 91. When the right end of the fin 71 abuts against the left end of the insertion section 9, the limiting block is located in the limiting groove 91, thereby limiting the fin 71 and preventing the fin 71 from opening.

[0040] A limiting sleeve 4 is fitted onto the end of the second support block away from the second plate 2. The left end of the limiting sleeve 4 is provided with a limiting hole 41 opposite to the rod. The diameter of the limiting hole 41 is larger than the diameter of the insertion section 9 and smaller than the diameter of the large diameter section 81, so that after the small diameter section 82 and the insertion section 9 are inserted into the second support block through the limiting hole 41, the step abuts against the left end of the limiting sleeve 4, thereby limiting the positioning member 3.

[0041] In this embodiment, when the positioning component 3 is installed, the extension rod 6 is not installed. At the same time, the large-diameter section 81 is located inside the sleeve 7, the small-diameter section 82 is opposite to the limiting part, and the insertion section 9 is located on the right side of the limiting part and limits the fin 71 through the cooperation of the limiting block and the limiting groove 91. When it is necessary to fix the first plate 1 and the second plate 2, the right end of the insertion section 9 is aligned with the receiving groove 11, and then the head 5 is subjected to the first impact, causing the head 5 to drive the rod to slide to the right, penetrating the first plate 1, and the rod enters the insulation cavity.

[0042] When the head 5 enters the limiting groove 91 and abuts against the side wall opposite to the opening of the limiting groove 91, the extension rod 6 is inserted into the sleeve 7 through the insertion hole 51. At this time, the extension rod 6 abuts against the large diameter section 81. Then, an impact is applied to the right on the extension rod 6, which pushes the fixing part 8 to the right. Since the head 5 abuts against the first plate 1, the head 5, sleeve 7 and limiting part no longer slide to the right. The extension rod 6 and the fixing part 8 slide to the right relative to the sleeve 7. The small diameter section 82 and the insertion section 9 are inserted into the second support block through the limiting hole 41, connecting the fixing part 8 to the second support block.

[0043] At the same time, the large-diameter section 81 slides out of the sleeve 7 to the right, pushing the fins 71 to the outer edges that are far apart from each other, causing the fins 71 to bend and deform and open outwards. When filling the aerogel felt, a large pressure is applied to the first plate 1 and the second plate 2 towards the insulation cavity, and the point of force application covers the end of the extension rod 6 to position the extension rod 6.

[0044] In actual implementation, the length of the extension rod 6, sleeve 7, and large-diameter section 81, along with the thickness of the insulation cavity, ensure that when the step abuts against the limiting sleeve 4, the left end of the large-diameter section 81 remains inside the sleeve 7. When installing the extension rod 6, glue can be poured into the insertion hole 51 before inserting the extension rod 6 into the insertion hole 51. Before the glue solidifies, the extension rod 6 is inserted and slid to the right into the sleeve 7. After the glue solidifies, the extension rod 6, sleeve 7, and large-diameter section 81 can be fixed. Alternatively, the large-diameter section 81 can be set as a T-shaped structure, so that the left end of the large-diameter section 81 forms a locking block. When the large-diameter section 81 slides to the left relative to the sleeve 7, it cannot be completely dislodged from the sleeve 7, thereby further improving the connection strength between the first plate 1 and the second support block.

[0045] In this design, when the positioning element 3 is used, after the aerogel felt is filled, the fins 71, sleeve 7, and large-diameter section 81 are all wrapped by the aerogel felt and cannot be removed from the insulation cavity. Since the fins 71 are open at this time, the positioning element 3 is effectively prevented from detaching from the aerogel felt, increasing the connection strength between the first plate 1 and the aerogel felt. During aerogel filling, applying pressure towards the insulation cavity to the first plate 1 and the second plate 2 better limits their position, preventing the thickness of the formed aerogel felt from increasing. At this time, the abutment between the limiting sleeve 4 and the step further limits the position of the first plate 1 and the second plate 2, preventing them from approaching each other and causing a decrease in the thickness of the insulation cavity.

[0046] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
