Description

TECHNICAL FIELD

[0001] The present application relates to the field of composite boards, in particular to a prefabricated aerogel thermal insulation composite board. BACKGROUND

[0002] With the acceleration of urbanization and the upgrading of consumer demand, traditional on-site manual operation exposes problems such as uncontrollable construction period, serious resource waste, and low process standardization, for example, decoration waste accounts for more than 30% of the total amount of urban construction waste, the annual growth of labor cost exceeds 10%, and the delivery quality is difficult to guarantee due to the uneven technical level of workers. Aerogel is a new type of nanometer porous structure material with excellent performance, aerogel felt is mainly used in the field of building, and has the functions of thermal insulation and sound insulation, but due to the production process and powder falling problem of aerogel felt, the application of aerogel felt in the field of building is limited.

[0003] If a large amount of glue is used to fix the aerogel felt, it is easy to cause harm to the human body, therefore, a composite board is needed to solve the problem of dust falling and reduce harm to the human body. SUMMARY

[0004] The present application aims to provide a prefabricated aerogel thermal insulation composite board to solve the problem of dust falling and reduce harm to the human body.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows: a prefabricated aerogel thermal insulation composite board, comprising a composite board, the composite board comprising a panel, a thermal insulation board and a back plate, a plurality of ribs are arranged on the inner side of the panel, the ribs are embedded in the thermal insulation board, a connecting piece is arranged on the back plate, the connecting piece penetrates the back plate, the thermal insulation board and the ribs in sequence, so as to connect the back plate, the thermal insulation board and the ribs.

[0006] The beneficial effects of the present application are as follows: 1. The thermal insulation board is clamped by the panel and the back plate, which reduces the area of the thermal insulation board exposed to the outside, thereby reducing the degree of powder falling of the aerogel felt and protecting human health.

[0007] 2. Since the composite board increases the back plate to fix the thermal insulation board, the overall thickness of the composite board is increased, thereby increasing the cost and reducing the indoor clearance; therefore, in the present application, ribs are added to the inner side of the panel, and through experiments, the thickness of the panel in the present application is only 6-8mm under the condition of the same structural bearing capacity, if no ribs are arranged, the thickness of the panel is 8-10mm, therefore, the present application reduces the total thickness of the composite board, the thickness is lower, the indoor space is saved, and the installation weight is reduced.

[0008] 3. In this scheme, the aerogel roll material is layered into a whole board, which not only does not fall off dust, but also has no adhesive and no formaldehyde release, improving the integrity of the material, pre-assembling the decorative layer, reducing energy consumption and carbon emissions through industrial means, and reducing 80% of the site waste compared with the traditional way of assembly type decoration, and the material utilization rate is increased to more than 95%.

[0009] 4. The composite board is suitable for factory assembly molding and is assembled by standardized products without the need for on-site processing; it can ensure quality and improve installation efficiency. The ribs increase the integrity of the composite board, making it stronger and easier to transport and transfer.

[0010] Further, the panel is provided with a countersunk screw, which penetrates the panel and enters the rib.

[0011] Further, the rib thickness is 1 / 3-2 / 3 of the thickness of the insulation board.

[0012] Further, the rib is a plurality of discontinuous short ribs or long ribs arranged throughout, and the long rib is parallel to the long edge or short edge of the panel.

[0013] Further, the insulation board is aerogel felt, cement-based aerogel insulation board, or inorganic foaming aerogel insulation board.

[0014] Further, the rib includes an edge rib, which is arranged at the edge of the panel, and an L-shaped embedded part is arranged on the edge rib, which extends out of the panel, and the L-shaped embedded part is used to connect with a hanging part, which is used to hang on the wall or the keel.

[0015] Further, a threaded sleeve is embedded in the panel, the end of the threaded sleeve penetrates the rib, the connecting part is a connecting screw, a countersunk screw hole is arranged on the back plate, and the connecting screw penetrates the countersunk screw hole, the insulation board and the threaded sleeve in sequence and is threadedly connected with the threaded sleeve.

[0016] Further, the connecting screw includes a screw head and a shank, 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 shank penetrates the rotating screw head and the dry hanging screw head in sequence, and the other end of the shank penetrates the countersunk screw hole, the insulation board and the threaded sleeve in sequence and is threadedly connected with the threaded sleeve. Further, the keel is arranged horizontally on the wall, a plurality of limiting parts are arranged on the lower side of the keel, a limiting groove is arranged in the limiting part, a strip-shaped first limiting hole is arranged on the side of the limiting groove, the upper end of the first limiting hole is connected with 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 in clearance fit, and the connecting position of the rotating screw head and the dry hanging screw head is in the first limiting hole.

[0017] Further, a sliding groove is arranged on the keel, the lower side of the sliding groove is communicated with the plurality of limiting grooves, and the dry hanging screw head is slidingly arranged in the sliding groove or the limiting groove. The limiting piece is arranged between the sliding groove and the limiting groove, and is used for blocking the dry hanging screw head from sliding into the limiting groove.

[0018] Further, the second limiting hole is arranged on the side surface of the limiting groove, all the limiting holes are arranged on a straight line, the limiting piece is a limiting strip, the shape of the limiting strip is matched with the second limiting hole, and the hook is connected with the screw head of the rotating screw. The limiting strip is sequentially arranged through the second limiting holes, the bottom of the second limiting hole is sharp, the composite board is slid on the sliding groove through the dry hanging screw head, the limiting strip is pulled out from the second limiting hole of the corresponding limiting part after the composite board is slid to the end of the sliding groove, the dry hanging screw head falls into the limiting groove, and the hook is hung on the keel.

[0019] The scheme has the following effects: 1. The panel is a cement fiber board, a calcium silicate board or a bamboo charcoal fiber board, the countersunk screw is arranged to connect the panel and the panel, the prefabricated countersunk screw is used to ensure the panel is beautiful, and the aerogel felt is cut by 1 / 3-2 / 3 and then integrally attached to the panel.

[0020] 2. The connecting piece (screw) is arranged at the rib position, and the end of the connecting piece is inserted into the rib and stably fixed.

[0021] 3. In the prior art, the hanging piece is usually arranged on the composite board, the hanging piece is hung on the keel, and the keel is horizontally fixed on the wall; however, for a larger room, such as a large conference room or a multi-functional exhibition hall, a large number of composite boards need to be laid, two people need to continuously lift the composite boards to the specified position and hang them, which is time-consuming and laborious, and the engineering quantity is huge; therefore, in the scheme, the outer side of the keel is designed as a sliding groove, so that the composite board can slide thereon.

[0022] 4. In order to facilitate sliding, the dry hanging screw head is arranged in the sliding groove to facilitate sliding, in order to ensure the stability of the structure, the dry hanging screw head is fixedly connected with the composite board, therefore, the dry hanging screw head will be greatly abraded when sliding, therefore, the dry hanging screw head can connect the composite board with the keel, but cannot be used as a long-term connecting structure, therefore, the hook is further arranged on the composite board and can be hung on the keel as a long-term supporting structure.

[0023] 5. In order to realize automatic positioning and stopping after the composite board is slid to the position, the limiting part is arranged at the design position in the scheme, the dry hanging screw head will fall into the limiting groove below and will not continue to slide forward after the dry hanging screw head is slid to the limiting part; at this time, the hook also falls, so as to be hung on the keel, and the main connecting position of the composite board is switched from the dry hanging screw head to the hook.

[0024] 6. Each composite panel is provided with a corresponding limiting slot. Before the composite panel passes through the non-corresponding limiting slot, the limiting strip needs to be used to seal the limiting slot to prevent the non-corresponding dry hanging screw head from falling into the limiting slot. When the corresponding dry hanging screw head appears, the limiting strip is pulled out. However, not every limiting slot is close to the edge of the composite panel, so not all limiting strips are easy to pull out. Therefore, in this scheme, one limiting strip seals multiple limiting slots at the same time. When it is necessary to unseal one limiting slot, the limiting strip is pulled out by a specific length at the end of the limiting strip. The limiting strip does not need to be flush with the upper end of the limiting slot. A buffer transition slope can be set to ensure that the dry hanging screw head can slide out after entering the upper part of the limiting slot and being supported on the limiting strip. Since the limiting strip mainly serves as temporary support, the limiting strip does not need to have sufficient rigidity and can have a certain flexibility to facilitate the extraction of the limiting hole.

[0025] 7. To save time, one limiting strip is usually inserted through the second limiting hole of multiple limiting parts. In a larger conference room, after the composite panel is slid into place, the limiting strip is pulled out, and it is not clear where the limiting strip is pulled to. It is necessary to go there to confirm whether the dry hanging screw head falls into the limiting slot. If each one is checked once, it is very time-consuming and consumes a lot of physical energy. In this scheme, the bottom of the second limiting hole is sharp, the shape of the limiting strip matches the second limiting hole, and the limiting strip is also sharp at the bottom. When the dry hanging screw head slides into the limiting slot and is supported on the limiting strip, the weight of the composite panel is transferred to the limiting strip, and a large pressure is generated between the limiting strip and the bottom of the second limiting hole. At this time, pulling out the limiting strip will generate a large resistance. Once the limiting strip is pulled out of the corresponding second limiting hole, the resistance decreases, and it is not necessary to go there to check it again, which is convenient and fast.
