Description

Technical Field

[0001] This invention relates to the field of aerogel building materials, specifically to ribbed reinforced aerogel insulation composite panels. Background Technology

[0002] Traditional building insulation and decoration construction processes are generally characterized by complex procedures, low resource utilization, and serious environmental pollution. In existing technologies, the construction of the main building structure and interior decoration are typically carried out in stages. After the insulation layer is installed, secondary treatment of the base layer is still required during the decoration stage, such as wall leveling and reinforcement, which involves repetitive work. This not only results in a large consumption of materials and human resources but also significantly prolongs the construction period and leads to increased construction waste and carbon emissions, making it difficult to meet the requirements of current green building and "dual carbon" goals.

[0003] Furthermore, conventional building insulation and decoration materials widely rely on formaldehyde-containing adhesives (such as urea-formaldehyde resin) during production and use. These adhesives continuously release volatile harmful substances such as formaldehyde and benzene compounds during board manufacturing, construction, and long-term use, seriously affecting indoor environmental quality and the health of residents. Especially in sensitive settings such as children's rooms and elderly residences where air quality requirements are high, traditional materials exhibit significant environmental shortcomings: a trade-off between high formaldehyde release and low mechanical properties, creating a so-called "environmental protection-performance" dilemma.

[0004] Aerogel, as a high-performance nanoporous thermal insulation material, has shown promising application prospects in the field of building insulation, but its practical promotion still faces many bottlenecks. For example, aerogel felt has problems such as easy powdering and insufficient structural strength, and often needs to be fixed with organic adhesives, which further exacerbates the risk of formaldehyde release—especially in heating or high humidity environments, the aging and decomposition of adhesives are accelerated, leading to increased release of pollutants, which seriously restricts its applicability in healthy buildings.

[0005] Therefore, it is necessary to develop a new type of composite board that can integrate thermal insulation and decorative functions, improve construction efficiency and reduce overall construction costs, fundamentally solve the problem of powder shedding of aerogel materials, and significantly reduce the release of harmful substances, so as to meet the development trend of green and healthy buildings. Summary of the Invention

[0006] The present invention aims to provide a ribbed reinforced aerogel insulation composite board that integrates insulation and decoration functions, improves construction efficiency, and solves the problem of powder shedding of aerogel materials.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a ribbed reinforced aerogel thermal insulation composite board, comprising a composite board, the composite board comprising a panel, a thermal insulation board and connectors, the inner side of the panel is provided with a plurality of ribs, the ribs are embedded in the thermal insulation board, the thermal insulation board is provided with an air-barrier membrane on the side away from the panel, and the connectors are sequentially inserted into the air-barrier membrane, the thermal insulation board and the ribs, thereby connecting the air-barrier membrane, the thermal insulation board and the ribs.

[0008] The beneficial effects of this plan are: 1. By sealing both sides of the insulation board with the panel and the air-barrier membrane, the area of ​​the insulation board exposed to the outside is reduced, the degree of dust shedding from the aerogel felt is reduced, and human health is protected.

[0009] 2. To control the thickness of the composite panel, this solution uses a flexible air-barrier membrane to seal one side of the insulation panel. The air-barrier membrane has good sealing properties and a small thickness, saving indoor space and reducing installation weight.

[0010] 3. In this solution, ribs are added to the inside of the panel. After testing, it was found that under the same structural load-bearing capacity, the panel thickness required in this solution is only 6-8mm. If the ribs are not set, the panel thickness is 8-10mm. Therefore, this solution reduces the total thickness of the composite panel, resulting in a thinner panel, saving indoor space and reducing installation weight.

[0011] 4. In this solution, by combining the panel and the air-barrier membrane, the layered structure of the aerogel roll material can be optimized into a whole board. Not only does it not shed dust, but it also has virtually no organic adhesive materials and no formaldehyde release, which improves the integrity of the material. A prefabricated decorative layer is also provided. Energy consumption and carbon emissions are reduced through industrialization. Compared with traditional methods, prefabricated decoration can reduce on-site waste by 80% and increase the material utilization rate to over 95%.

[0012] 5. Composite panels are suitable for factory assembly, being standardized products that require no on-site processing; this ensures quality and improves installation efficiency. Ribs increase the overall integrity of the composite panel, resulting in higher strength and easier handling and transportation.

[0013] Furthermore, the ribs are a number of discontinuous short ribs or long ribs arranged along the entire length, with the long ribs parallel to the long or short side of the panel.

[0014] Furthermore, the ribs include edge ribs, which are set at the edge of the panel. The edge ribs are provided with L-shaped embedded parts that extend beyond the panel. The L-shaped embedded parts are used to connect with hangers, which are used to hang on the wall or keel.

[0015] Furthermore, the air-barrier membrane is wrapped around the insulation board. The air-barrier membrane can be a building waterproof and breathable membrane, geotextile, polyester fiber felt, PVC fiberglass coated felt, skeleton non-woven fabric or cement fiberglass coated felt.

[0016] Furthermore, the connector is a connecting screw, which is inserted sequentially into the air-barrier membrane, the insulation board, and the ribs.

[0017] Furthermore, the connector is a cable tie, which is inserted into the air-barrier membrane, the insulation board and the ribs in sequence, and then exits from the ribs, the insulation board and the air-barrier membrane in sequence.

[0018] Furthermore, the insulation board has several mesh fabrics on the side away from the panel, with the mesh fabrics positioned at the corresponding positions of the cable ties, and the air-tight membrane located between the insulation board and the mesh fabrics.

[0019] Furthermore, the connector is a connecting screw, which includes a screw head and a rod body. The screw head includes a rotating screw head and a dry-hanging screw head. The thickness of the dry-hanging screw head gradually decreases from the middle to the edge. The rotating screw head is a disc. One end of the rod body passes through the rotating screw head and the dry-hanging screw head in sequence, and the other end of the rod body passes through the countersunk screw hole and the insulation plate in sequence and is threadedly connected to the threaded sleeve. It also includes a keel, which is horizontally installed on the wall. Several limiting parts are provided on the lower side of the keel. A limiting groove is provided in the limiting part. A strip-shaped first limiting hole is provided on the side of the limiting groove. The upper end of the first limiting hole is connected to the upper edge of the limiting groove. The dry-hanging screw head is accommodated in the limiting groove. The dry-hanging screw head and the side wall of the limiting groove are clearance-fitted. The connection position of the rotating screw head and the dry-hanging screw head is in the first limiting hole.

[0020] Furthermore, the keel is provided with a sliding groove, the lower side of which is connected to several limiting grooves, and the dry-hanging screw head is slidably set in the sliding groove or limiting groove. A limiting element is provided between the sliding groove and the limiting groove. The limiting element is used to prevent the dry-hanging screw head from sliding into the limiting groove.

[0021] Furthermore, each side of the limiting groove has a second limiting hole, all of which are in a straight line. The limiting element is a limiting strip, the shape of which matches the second limiting hole. A hook is bolted to the rotating screw head. The limiting strip passes through several second limiting holes in sequence. The bottom of the second limiting hole is sharp. The composite panel slides on the slide groove through the dry-hanging screw head. After the composite panel slides to the end of the slide groove, the limiting strip is pulled out from the second limiting hole of the corresponding limiting part. The dry-hanging screw head falls into the limiting groove and the hook is hung on the keel.

[0022] This solution also has the following effects: 1. The panel is made of cement fiberboard, calcium silicate board or bamboo charcoal fiberboard. Countersunk screws are used to connect the panels. Pre-made countersunk screws ensure the appearance of the panel. The insulation board (aerogel felt) is cut to 1 / 3-2 / 3 at the rib position and then attached to the panel as a whole.

[0023] 2. Install connectors (connecting screws) at the rib positions, insert the ends of the connectors into the ribs and secure them firmly.

[0024] 3. To make the connection between the insulation board and the ribs more secure, the connectors are tied with cable ties for a more stable fit. However, to prevent powder from falling off, an air-barrier membrane is used in this solution. To prevent the cable ties from damaging the air-barrier membrane, a mesh cloth is added to distribute the pressure of the cable ties, thereby protecting the air-barrier membrane and the insulation board. The mesh cloth is used to press the air-barrier membrane and the insulation board together.

[0025] 4. In existing technologies, hangers are usually installed on composite panels, which are then hung on keels, which are horizontally fixed to the wall. However, for larger rooms, such as large conference rooms and multi-functional exhibition halls, a large number of composite panels need to be laid, requiring two people to continuously lift the composite panels to the designated location and hang them, which is time-consuming, labor-intensive, and involves a huge amount of work. Therefore, in this solution, the outer side of the keel is designed as a sliding groove to facilitate the sliding of the composite panels.

[0026] 5. To facilitate sliding, dry-hanging screw heads are installed in the sliding groove. To ensure the stability of the structure, the dry-hanging screw heads are fixedly connected to the composite panel. Therefore, the dry-hanging screw heads will experience significant wear against the side wall of the sliding groove during sliding. Thus, although the dry-hanging screw heads can connect the composite panel to the keel, they cannot serve as a long-term connection structure. Therefore, hooks are also provided on the composite panel, which can be hung on the keel as a long-term support structure.

[0027] 6. In order to achieve automatic positioning and stopping after the composite panel slides into place, this solution sets a limiting part at the design position. When the dry-hanging screw head slides to the limiting part, it will fall into the limiting groove below and stop sliding forward. At this time, the hook will also fall down at the same time, so as to hang on the keel. The main connection position of the composite panel is changed from the dry-hanging screw head to the hook.

[0028] 7. Each composite panel has a corresponding limiting groove. Before the composite panel passes through an incorrect limiting groove, a limiting strip needs to be installed to seal the groove, preventing the incorrect dry-hanging screw head from falling into it. The limiting strip is then removed before the correct screw head appears. However, not every limiting groove is close to the edge of the composite panel, so not all limiting strips are easy to remove. Therefore, in this solution, one limiting strip seals multiple limiting grooves simultaneously. When it is necessary to unseal a limiting groove, the limiting strip is pulled out a specific length from its end. The limiting strip does not need to be flush with the top of the limiting groove. A buffer slope can be set to ensure that the dry-hanging screw head can slide out after entering the upper part of the limiting groove and being supported on the limiting strip. Since the limiting strip mainly serves as temporary support, it does not need sufficient rigidity and can have a certain degree of flexibility to facilitate removal from the limiting hole.

[0029] 8. To save time, a limiting strip is usually passed through the second limiting hole of multiple limiting parts. In a large conference room, after the composite panel slides into place, it is unclear which position the limiting strip has been pulled to after pulling it out. It is necessary to walk over to check whether the dry-hanging screw head has fallen into the limiting groove. If each one is checked, it is a waste of time and energy. In this design, the bottom of the second limiting hole is sharp, and the shape of the limiting strip matches the second limiting hole. The limiting strip also has a sharp bottom. When the dry-hanging screw head slides into the limiting groove and is supported on the limiting strip, the weight of the composite panel is transferred to the limiting strip, generating a huge pressure between the bottom of the limiting strip and the second limiting hole. At this time, pulling the limiting strip will generate a large resistance. Once the limiting strip is pulled out of the corresponding second limiting hole, the resistance decreases, indicating that it has been pulled out. There is no need to go and check it, which is convenient and quick. Attached Figure Description

[0032] Example 1 Example 1 is basically as follows Figure 1 As shown: Ribbed reinforced aerogel insulation composite panel, including a composite panel, which includes a panel 1, an insulation panel 2, and an air-barrier membrane 3.

[0033] The inner side of panel 1 is provided with several ribs 11, which are several discontinuous short ribs or long ribs arranged along the entire length, with the long ribs parallel to the long or short side of panel 1. Figure 2 It is a longitudinal rib. Figure 3 It is a longitudinal short rib. Figure 4 It is a transverse long rib. Figure 5 It is a transverse short rib. Rib 11 and panel 1 are integrally formed or connected by screws. When connected by screws, such as Figure 1 As shown, the panel 1 is provided with several countersunk screws 12, which pass through the panel 1 and into the ribs 11. The panel 1 is 8-10mm thick, and the thickness of the ribs 11 is 1 / 3-2 / 3 of the thickness of the insulation board 2. In this embodiment, the thickness of the ribs 11 is 3mm.

[0034] Panel 1 is made of cement fiberboard, calcium silicate board, gypsum board, wood-plastic composite material (such as bamboo charcoal fiberboard), medium density fiberboard, plywood or blockboard; insulation board 2 is made of aerogel felt, cement-based aerogel insulation board 2, inorganic foamed aerogel insulation board 2; and air barrier 3 is made of building waterproof and breathable membrane, geotextile, polyester fiber felt, PVC fiberglass coated felt, skeleton non-woven fabric or cement fiberglass coated felt.

[0035] Ribs 11 are embedded in the insulation board 2. The air-barrier membrane 3 is set on the side of the insulation board 2 away from the panel 1. The air-barrier membrane 3 wraps the side edge of the insulation board 2. The edge sealing adopts the conventional existing board edge sealing method, which will not be described in detail. Several mesh cloths 6 are provided on the side of the insulation board 2 away from the panel 1. In this embodiment, the mesh cloth 6 is an alkali-resistant fiberglass mesh cloth 6. The mesh cloth 6 is set at the corresponding position of the cable tie 7. The air-barrier membrane 3 is located between the insulation board 2 and the mesh cloth 6.

[0036] The connector is a cable tie 7. The cable tie 7 is inserted into the mesh of the mesh fabric 6, the air barrier membrane 3, the insulation board 2 and the rib 11 in sequence, and then it is inserted out of the rib 11, the insulation board 2, the air barrier membrane 3 and the mesh of the mesh fabric 6 in sequence. Finally, the two ends are tied tightly into a ring.

[0037] Example 2 Example 2 is based on Example 1: Rib 11 includes side ribs, which are set at the edge of panel 1. L-shaped embedded parts are provided on the side ribs, which extend beyond panel 1. The L-shaped embedded parts are used to connect with the hangers, which are used to hang on the wall or keel 5.

[0038] Example 3 The difference between Example 3 and Example 1 is as follows: Figure 6 As shown, the mesh cloth 6 is removed, and the connector is replaced with the connecting screw 4. The connecting screw 4 is inserted into the air-barrier membrane 3, the insulation board 2 and the rib 11 in sequence.

[0039] Example 4 Example 4 is based on Example 3: such as Figure 7 As shown, the air-barrier membrane 3 is wrapped around the insulation board 2, that is, the air-barrier membrane 3 covers all surfaces of the insulation board 2, including the side of the insulation board 2 closest to the panel 1. Figure 7 In the middle, the connecting part is the connecting screw 4. Depending on the actual situation, the connecting part can be replaced by the cable tie 7.

[0040] Example 5 Example 5, based on Example 3 or Example 4, further includes corner brackets, limiting strips 59, and elongated keel 5. The sides of the corner brackets are bolted to the wall, and the upper surface of the corner brackets is bolted to the keel 5. The keel 5 is as follows... Figures 8-11 As shown, keel 5 is set horizontally, as... Figure 8 As shown, the left side of the keel 5 is the wall. The keel 5 includes an integrally formed horizontal part 51 and a vertical part 52. The horizontal part 51 is bolted to the upper surface of the corner bracket. The right end of the horizontal part 51 is connected to the lower end of the vertical part 52. The lower surface of the vertical part 52 has several limit parts 55 integrally formed at equal intervals. The upper end of the vertical part 52 is provided with a triangular notch 53 on the side near the wall.

[0041] A sliding groove 54 is provided inside the vertical part 52, and the sliding groove 54 extends through the length of the vertical part 52. A limiting groove 56 is provided inside the limiting part 55, and the upper end of the limiting groove 56 is connected to the sliding groove 54. A corresponding strip-shaped first limiting hole 57 is provided on the side of the limiting groove 56 and the sliding groove 54 away from the wall. The length of the first limiting hole 57 is determined according to the length of the sliding groove 54 and the limiting groove 56. Along the length of the slide groove 54, a second limiting hole 58 is provided on the side of the limiting part 55. The cross-section of the second limiting hole 58 is a right triangle with the right angle side at the top and the acute angle at the bottom. The second limiting hole 58 passes through the limiting part 55 along the length of the slide groove 54. The second limiting grooves 56 of several limiting parts 55 are collinear and adjacent to the lower surface of the vertical part. The cross-section of the limiting strip 59 matches the shape of the second limiting hole 58. The limiting strip 59 passes through several second limiting holes 58. In this embodiment, one limiting strip 59 passes through four second limiting holes 58 at the same time. Two rows of connecting screws 4 are provided on a composite plate, with two connecting screws 4 in each row.

[0042] The connecting screw 4 includes an integrally formed screw head and a rod body 43. The rod body 43 passes through the air-insulating membrane 3 and the insulation board 2 in sequence. The screw head is positioned between the air-insulating membrane 3 and the vertical plate. The screw head includes a rotating screw head 41 and a dry-hanging screw head 42. The shape of the dry-hanging screw head 42 matches the cross-sectional shape of the groove 54. The dry-hanging screw head 42 is butterfly-shaped, that is, a flat, slightly thicker in the center and thinner at the edges, circular shape. The side of the dry-hanging screw head 42 closest to the vertical part 52 is flat, and the other side of the dry-hanging screw head 42 is flush with the rotating screw. The head 41 is connected in the middle. The rotating screw head 41 is a disc. One end of the rod body 43 passes through the rotating screw head 41 and the dry-hanging screw head 42 in sequence. The other end of the rod body 43 passes through the countersunk screw hole and the insulation plate 2 in sequence and is threadedly connected to the threaded sleeve. The rotating screw head 41 is provided to facilitate the rotation of the connecting screw 4 so that it is threadedly connected to the threaded sleeve. A hook 44 is integrally formed on the rotating screw head 41. The shape of the hook 44 matches the triangular notch 53 at the upper end of the vertical part 52 so that the hook 44 can be hung on the vertical part 52.

[0043] In the initial state, such as Figure 9 As shown, the dry-hanging screw head 42 is slidably disposed in the limiting groove 56, and the dry-hanging screw head 42 and the side wall of the limiting groove 56 are in clearance fit. The part of the rod body 43 located between the rotating screw head 41 and the dry-hanging screw head 42 is accommodated in the first limiting hole 57. When the dry-hanging screw head 42 passes the position where the limiting part 55 is located, such as Figure 10 As shown, since the limiting strip 59 is inserted into the second limiting hole 58, the dry-hanging screw head 42 will not fall into the limiting groove 56, thus continuing to push the composite panel and allowing the dry-hanging screw head 42 to slide forward. The height of the second limiting hole 58 is set according to the actual situation. If the limiting strip 59 in the second limiting hole 58 is too low and forms a groove, causing the dry-hanging screw head 42 to be unable to slide out of the groove, then an inclined slope needs to be set on both sides of the limiting groove 56 as a transition.

[0044] When the dry-hanging screw head 42 slides to the designed position, it rests on the limiting strip 59. Then, the limiting strip 59 is pulled out, and the dry-hanging screw head 42 falls into the limiting groove 56. Figure 11 As shown, hook 44 is also hung on vertical part 52, thus simulating manual hanging of composite board on keel 5, saving a lot of manpower.

[0045] Example 6 The difference between Example 6 and Example 1 is as follows: Figure 10 As shown, panel 1 and rib 11 are integrally formed, and countersunk screws 12 are omitted.
