Description

Technical Field

[0001] The present invention relates to the technical field of building materials, and in particular to a prefabricated compressive thermal insulation wall panel and its compressive member. Background Art

[0002] In recent years, prefabricated buildings have become increasingly popular. Compared with traditional cast-in-place buildings, prefabricated buildings can manufacture building components and fittings (such as floor slabs, wall panels, stairs, balconies, etc.) in batches like machine production, transferring a large amount of work that should be done on-site to the factory. Then, the building components and fittings processed and manufactured in the factory are transported to the building construction site for assembly and installation, significantly improving the simplicity of building construction and the efficiency of on-site construction.

[0003] When manufacturing prefabricated thermal insulation wall panels, after the composite thermal insulation board is manufactured, an inner layer of concrete wall panel needs to be cast on the outer surface of the composite thermal insulation board. Currently, when casting the cast-in-place concrete wall panel, the connection strength between the thermal insulation wall panel and the post-cast concrete wall panel is considered, and many methods and components for improving its connection strength have been proposed. For example, in the invention patent with the patent number "201810753274.6" and the name "A Prefabricated Wall Panel Thermal Insulation Structure and Its Construction Method", a method for improving the connection between the thermal insulation wall panel and the post-cast concrete wall panel is disclosed, that is, by embedding a connecting member in the thermal insulation wall panel. When casting the inner layer of concrete wall panel on the outer surface of the thermal insulation wall panel, the connecting member can be cast into the concrete wall panel together, so as to connect the thermal insulation wall panel and the concrete wall panel, making the connection between the thermal insulation board and the concrete wall panel closer and improving the connection strength between the two. However, when casting the concrete wall panel on the outer surface of the thermal insulation board, insufficient consideration is given to whether the compressive strength of the thermal insulation board itself is sufficient. Because when casting concrete, the concrete mortar actually exerts a great extrusion force on the thermal insulation board, and relying only on the strength of the board itself is not enough to resist the external pressure. As a result, the thermal insulation board is easily deformed under the extrusion of the concrete, leading to serious deformation of the final prefabricated wall panel product, and the engineering quantity required for its later repair is large, significantly increasing the production cost. Summary of the Invention

[0004] The purpose of the present invention is to solve the above technical problems and provide a prefabricated compressive thermal insulation wall panel and its compressive member. When the composite thermal insulation board with compressive support rods and strengthening meshes is poured together with the post-cast concrete wall panel after assembly, the compressive support rods are interspersed inside the composite thermal insulation board and the strengthening meshes are on the outside, which can significantly improve the compressive strength and tensile strength of the composite thermal insulation board, so as to ensure that the composite thermal insulation board will not deform during casting, and the surface of the finally formed prefabricated compressive thermal insulation wall panel is flat and does not need to be repaired, which is beneficial to subsequent construction.

[0005] To achieve the above object, the present invention provides the following solutions: The present invention provides a compressive member for an assembled compressive and thermal insulation wall panel, including compressive support rods and strengthening meshes respectively attached to both sides of the composite thermal insulation board. One of the strengthening meshes is located between the composite thermal insulation board and the post-cast concrete wall panel and is integrally cast with the post-cast concrete wall panel. The compressive support rods pass through the composite thermal insulation board and connect the two strengthening meshes.

[0006] Preferably, the strengthening mesh is a plastic mesh sheet composed of transverse bars and longitudinal bars; one end of the compressive support rod is fixed at the intersection of the transverse bar and the longitudinal bar of one of the plastic mesh sheets, and the other end of the compressive support rod is a pointed head and protrudes with a conical convex ring; a through hole is provided at the intersection of the transverse bar and the longitudinal bar of the other plastic mesh sheet, and a conical clamping groove matching with the conical convex ring is provided on the inner wall of the through hole.

[0007] Preferably, a connecting rod extending into the interior of the post-cast concrete wall panel is fixedly connected to the through hole, and the connecting rod is coaxially arranged with the compressive support rod.

[0008] Preferably, the strengthening mesh is a steel mesh sheet composed of transverse bars and longitudinal bars, a clamping groove for clamping the transverse bar or the longitudinal bar is provided on the compressive support rod, and one end of the compressive support rod extends into the interior of the post-cast concrete wall panel.

[0009] Preferably, the end of the compressive support rod extending into the interior of the post-cast concrete wall panel is a pointed head.

[0010] There is also provided an assembled compressive and thermal insulation wall panel, which adopts the compressive member of the assembled compressive and thermal insulation wall panel described above, including a composite thermal insulation board located between the two strengthening meshes, and a post-cast concrete wall panel integrally cast with one side of the composite thermal insulation board. The compressive support rods pass through both sides of the composite thermal insulation board and are connected to the two strengthening meshes.

[0011] Preferably, the composite thermal insulation board includes a waterproof and thermal insulation composite layer and fiberglass mesh cloths located on both sides of the waterproof and thermal insulation composite layer. The two fiberglass mesh cloths are sewn together by fiberglass threads.

[0012] Preferably, the waterproof and thermal insulation composite layer includes a thermal insulation layer and a waterproof layer attached to one side of the thermal insulation layer.

[0013] Preferably, the thermal insulation and waterproof composite layer includes a thermal insulation layer and waterproof layers attached to both sides of the thermal insulation layer.

[0014] Preferably, the thermal insulation and waterproof composite layer includes a waterproof layer and thermal insulation layers attached to both sides of the waterproof layer.

[0015] The present invention has achieved the following technical effects compared with the prior art:

[0016] 1. In the present invention, the compression-resistant member includes a compression-resistant support rod and two reinforcing meshes. After the compression-resistant support rod in the middle of the composite insulation board connects and locks the reinforcing meshes on both sides of the composite insulation board, the reinforcing meshes and the composite insulation board are integrated into a whole. The stress points of external tensile and compressive forces are all distributed at the joint points of the reinforcing mesh and the compression-resistant support rod. The entire pressure is borne by the compression-resistant support rod in the middle, protecting the internal composite insulation board from being deformed or damaged by extrusion, and geometrically improving the overall tensile strength and compressive strength of the composite insulation board. Therefore, when casting the post-cast concrete, the composite insulation board will not be extruded and deformed by the concrete mortar. At the same time, after casting the post-cast concrete wall panel, the reinforcing mesh and the post-cast concrete wall panel are cast integrally, which can also improve the connection tightness between the composite insulation board and the post-cast concrete wall panel, and significantly improve the connection strength.

[0017] 2. In the present invention, the reinforcing mesh can be a plastic mesh sheet with a self-contained compression-resistant support rod and a plastic mesh sheet with through holes. During use, it can be quickly assembled to improve the prefabrication speed. At the same time, after the conical convex ring is inserted into the conical card slot, the conical structures of the two can effectively prevent the end of the compression-resistant support rod from detaching from the through hole.

[0018] 3. In the present invention, a connecting rod is fixedly connected to the through hole. After casting the post-cast concrete wall panel, the connecting rod extends into the interior of the post-cast concrete wall panel, which can significantly improve the connection strength between the composite insulation board and the post-cast concrete wall panel, and then improve the integrity of the overall assembled compression-resistant insulation wall panel.

[0019] 4. In the present invention, the reinforcing mesh can be a steel mesh sheet. The compression-resistant support rod is provided with a card slot for clamping the transverse bars or longitudinal bars. At the same time, one end of the compression-resistant support rod can extend into the interior of the post-cast concrete wall panel. Through one compression-resistant support rod, it not only plays the role of connecting the two reinforcing meshes, but also plays the role of strengthening the connection with the post-cast concrete wall panel.

[0020] 5. In the present invention, for the assembled compression-resistant insulation wall panel, the composite insulation board can significantly improve its compressive and tensile strengths under the reinforcement of the compression-resistant member. At the same time, under the action of the reinforcing mesh, the connection strength between the post-cast concrete wall panel and the composite insulation board is also improved. If a plastic mesh sheet is used, the connecting rod will also be connected to the post-cast concrete wall panel. If a steel mesh sheet is used, the end of the compression-resistant support rod will be connected to the post-cast concrete wall panel, thereby greatly improving the connection strength between the post-cast concrete wall panel and the composite insulation board.

[0021] 6. In the present invention, the composite insulation board is sewn together with the glass fiber mesh cloth on both sides by glass fiber threads through a waterproof and thermal insulation composite layer. Under the action of the glass fiber mesh cloth and the glass fiber threads, the integrity of the composite insulation board can be improved, and the structural strength of the composite insulation board can be guaranteed. At the same time, the waterproof and thermal insulation composite layer is composed of a waterproof layer and a thermal insulation layer, and has both the functions of thermal insulation and waterproofing.

Specific implementation manners

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Embodiment 1

[0044] This embodiment provides a compressive member of an assembled compressive insulation wall panel, such as Figures 1 to 18As shown in the figure, it includes two reinforcing meshes 4 and several compressive support rods 3. The two reinforcing meshes 4 are respectively attached to both sides of the composite insulation board 1. After several compressive support rods 3 pass through the composite insulation board 1, they are connected to the two reinforcing meshes 4, so that the two reinforcing meshes 4 are closely attached to both sides of the composite insulation board 1, and the compressive capacity can be provided by the two reinforcing meshes 4 and several compressive support rods 3. When the formwork is set up and the concrete wall panel is poured from one side of one of the reinforcing meshes 4, the reinforcing mesh 4 on the outside of the composite insulation board 1 is equivalent to providing a protective net for the composite insulation board 1. The stress points of the external tensile force and pressure are all distributed at the joint points of the reinforcing mesh 4 and the compressive support rods 3, and the entire pressure is borne by the compressive support rods 3 in the middle, thus protecting the internal composite insulation board 1 from deformation or damage, so that the overall tensile strength and compressive strength of the composite insulation board 1 are increased geometrically, and it can resist the extrusion of the concrete layer, thereby avoiding the problem of deformation of the composite insulation board 1 caused by the extrusion of the concrete paste. At the same time, after the curing of the concrete layer is completed, the reinforcing mesh 4 will be formed together with the formed post-cast concrete wall panel 2, and it also plays a role in strengthening the connection between the composite insulation board 1 and the post-cast concrete wall panel 2, improving the tightness of the connection. After applying this compressive member, it not only achieves the purpose of avoiding the extrusion deformation of the composite insulation board 1 when pouring the concrete wall panel, but also achieves the effect of improving the connection strength between the composite insulation board 1 and the post-cast concrete wall panel 2. In order to achieve the effect of protecting the composite insulation board 1, the mesh size on the reinforcing mesh 4 should not be too large, and preferably the size is between 150 mm and 200 mm. The compressive support rods 3 are made of materials with low thermal conductivity to avoid forming a "thermal bridge" after being inserted into the composite insulation board 1 and reducing the insulation effect of the composite insulation board 1.

[0045] In this embodiment, as Figures 1 to 5As shown in the figure, both of the two reinforcing meshes 4 are plastic mesh sheets, which are composed of plastic cross ribs 5 and plastic longitudinal ribs 6, and their mesh openings are rectangular mesh openings. The compressive support rod 3 is also made of plastic. One end of the compressive support rod 3 is fixed on one of the reinforcing meshes 4, specifically at the intersection of the plastic cross rib 5 and the plastic longitudinal rib 6. Preferably, the compressive support rod 3 and the reinforcing mesh 4 are integrally formed. The other end of the compressive support rod 3 is a pointed head, which is beneficial to penetrate the composite insulation board 1. A conical convex ring 7 protrudes from the pointed end of the compressive support rod 3. A through hole 8 is provided at the intersection of the plastic cross rib 5 and the plastic longitudinal rib 6 of the other reinforcing mesh 4 for the pointed end of the compressive support rod 3 to be inserted. At the same time, the inner wall of the through hole 8 is recessed inward to form a conical clamping groove 9. After the conical convex ring 7 is snapped into the conical clamping groove 9, since both of them are conical structures, it can prevent the conical convex ring 7 from disengaging from the conical clamping groove 9. During specific use, first, make the compressive support rod 3 on the reinforcing mesh 4 with the compressive support rod 3 penetrate the composite insulation board 1, and make the reinforcing mesh 4 closely fit on the side of the composite insulation board 1. Then, buckle the through hole 8 on the reinforcing mesh 4 with the through hole 8 corresponding to the compressive support rod 3. After the conical convex ring 7 is inserted into the conical clamping groove 9, the reinforcing mesh 4 with the through hole 8 also closely fits on the composite insulation board 1, and the installation of the compressive member is completed. The number of the compressive support rods 3 depends on the situation. It can be like Figure 5 shown, covering all the intersections of the plastic cross rib 5 and the plastic longitudinal rib 6 of the reinforcing mesh 4, or it may not cover all of them, just evenly supplement several of them, as long as it can ensure sufficient compressive strength between the two reinforcing meshes 4. The reinforcing mesh 4 and the compressive support rod 3 can also be made of nylon material.

[0046] Furthermore, in this embodiment, as Figures 1 to 5 shown, the plastic cross rib 5 and the plastic longitudinal rib 6 should have a certain thickness, and their cross-sections can be rectangular, square, circular, elliptical, "I"-shaped or other shapes. Preferably, it is a square with a side length of 6 - 16 mm.

[0047] In order to further improve the connection strength between the composite insulation board 1 and the post-cast concrete wall panel 2, in this embodiment, as Figures 1 to 5 shown, a connecting rod 10 is fixedly connected to the through hole 8, and the connecting rod 10 is coaxially arranged with the compressive support rod 3. The connecting rod 10 can also be made of plastic material or nylon material. Preferably, the reinforcing mesh 4 and the connecting rod 10 are integrally formed. When casting the post-cast concrete layer, the connecting rod 10 will be formed together with the post-cast concrete wall panel 2, that is, the connecting rod 10 will be buried inside the post-cast concrete wall panel 2 to connect the reinforcing mesh 4 and the post-cast concrete wall panel 2.

[0048] In this embodiment, as Figures 7 to 9 shown, both of the two reinforcing meshes 4 are steel mesh sheets, which are welded by transverse steel bars 11 and longitudinal steel bars 11. Preferably, the diameter of the steel bar 11 is The compressive support rod 3 is made of a non-thermal conductive material, and one of the non-metallic non-thermal conductive materials such as nylon, polyethylene, polypropylene, and basalt fiber can be selected. Two card slots 12 are provided on the compressive support rod 3 for clamping on the transverse steel bars 11 and longitudinal steel bars 11 of the reinforcement mesh 4, preferably at the intersection of the transverse steel bars 11 and longitudinal steel bars 11. During use, first pass several compressive support rods 3 through the composite insulation board 1, then respectively attach the two reinforcement meshes 4 to the composite insulation board 1, adjust the positions of the compressive support rods 3, and clamp the two reinforcement meshes 4 into the two card slots 12 on the compressive support rods 3. One end of the compressive support rod 3 will exceed one end of the reinforcement mesh 4 by a certain distance for connection with the post-cast concrete wall panel 2.

[0049] Furthermore, referring to Figure 9 as shown, the end of the compressive support rod 3 extending into the post-cast concrete wall panel 2 is a pointed head. The pointed head facilitates penetrating the composite insulation board 1.

[0050] Embodiment 2

[0051] There is also provided an assembled compressive insulation wall panel, as Figures 1 to 18 shown, including a composite insulation board 1, a post-cast concrete wall panel 2, and a compressive member. The composite insulation board 1 is located between the two reinforcement meshes 4. The compressive support rod 3 passes through the composite insulation board 1 and connects the two reinforcement meshes 4. The reinforcement mesh 4 is closely attached to the side wall of the composite insulation board 1. One side of the composite insulation board 1 is the post-cast concrete wall panel 2 formed later. During specific prefabrication, first prefabricate the composite insulation board 1, then install the two reinforcement meshes 4 and the compressive support rod 3 on the composite insulation board 1, and finally set up the formwork and pour the post-cast concrete wall panel 2 on one side of the composite insulation board 1. The reinforcement mesh 4 on this side is integrally formed with the post-cast concrete wall panel 2. Supported by the compressive support rod 3, the two reinforcement meshes 4 can withstand the extrusion of the concrete, thereby reducing the large-range extrusion of the concrete on the composite insulation board 1. At the same time, in order to achieve the effect of protecting the composite insulation board 1, the mesh size on the reinforcement mesh 4 should not be too large. The concrete used for the post-cast concrete wall panel 2 can be the gravel concrete prepared by mixing ordinary Portland cement of building strength grade 42.5, gravel, pea gravel, yellow sand or quartz sand (with a fineness of 0.5 - 0.35) mm in a certain proportion, with ordinary Portland cement as the main component.

[0052] Furthermore, in this embodiment, as Figures 1 to 18 shown, the composite insulation board 1 includes a waterproof and thermal insulation composite layer and two layers of fiberglass mesh cloth 13. The two layers of fiberglass mesh cloth 13 are located on both sides of the waterproof and thermal insulation composite layer and are sewn together by fiberglass threads, thereby sewing the fiberglass mesh cloth 13 and the waterproof and thermal insulation composite layer into a whole. Referring to Figures 13 to 18 , when sewing between the two layers of fiberglass mesh cloth 13, the running direction of the fiberglass threads can be divided into normal sewing ( Figure 13)、Zonal encrypted seam, no seam in the radial direction( Figure 14 )、Radial encrypted seam, no seam in the zonal direction( Figure 15 )、Radial encrypted seam, no seam in the zonal direction( Figure 16 )、Zonal encrypted seam, normal seam in the radial direction( Figure 17 )、Radial encrypted seam, normal seam in the zonal direction( Figure 18 ) Six sewing thread - running methods. The specific methods and advantages of each method are as follows:

[0053] Normal seam:

[0054] 1. The row spacing of normal sewing is fixed, generally in a zonal - radial grid pattern of 60mm - 65mm. The stitch density is generally between 20mm - 38mm, mainly adjusted according to different material thicknesses and usage occasions. The higher the stitch density, the higher the tensile strength; conversely, the lower the stitch density, the lower the tensile strength. There are approximately 1388 stitches per square meter in normal sewing, and the running speed is not greater than 60 stitches per minute.

[0055] 2. For the composite insulation board 1 sewn by normal sewing, there are approximately 1388 stitches per square meter, and the mechanical strength is relatively high. The tensile strength in the direction perpendicular to the board surface can reach more than 100 kPa;

[0056] 3. It can be sewn and completed with one - time feeding, with relatively high production efficiency.

[0057] Zonal encrypted seam, no seam in the radial direction:

[0058] 1. Stop sewing in the radial direction. Sew in the zonal direction for the first time with feeding. After completion, offset the processed board by 30mm, and then sew with reverse feeding for the second time (rotate or flip 180°);

[0059] 2. Rotate or flip 180° for the second time, and sew again with zonal feeding. The advantage of reverse feeding: It avoids the defects of easy thread - off and thread - pulling in two - time sewing in the same direction;

[0060] 3. The row spacing of sewing is fixed, generally 60mm - 65mm, and the stitch density is generally between 20mm - 38mm, mainly adjusted according to different material thicknesses and usage occasions. The higher the stitch density, the higher the tensile strength; conversely, the lower the stitch density, the lower the tensile strength. There are also 1388 stitches per square meter in the zonal one - way encrypted seam and no seam in the radial direction, and the running speed is not greater than 60 stitches per minute.

[0061] 4. For the composite insulation board 1 sewn with one - way encryption, the number of stitches does not decrease, and there are also 1388 stitches per square meter. The mechanical strength is second only to that of the normal seam:

[0062] 5. Because one sewing process is reduced, the production efficiency is increased by more than 50% compared with normal sewing.

[0063] Radial encrypted seam: no seam in the zonal direction:

[0064] The weft sewing stops. Rotate or flip it 180° for the second time, and feed the material radially and sew again. Advantages of reverse feeding: It avoids the defects of easy thread-off and thread-pulling in two sewings in the same direction;

[0065] Weft direction: Dense sewing, Radial direction: Normal sewing:

[0066] Operate according to normal sewing. The row spacing is generally fixed at 60mm - 65mm in a weft and warp grid pattern, and the stitch density is generally between 20mm - 38mm. It is mainly adjusted according to the thickness of different materials and the usage occasions. The denser the stitch density, the higher the tensile strength. Conversely, the looser the stitch density, the lower the tensile strength. For weft dense sewing and radial normal sewing, there are approximately 2083 stitches per square meter, and the running speed is not greater than 60 stitches per minute;

[0067] 2. The radial sewing stops. Offset the processed composite insulation board 1 by 30mm in the weft direction, and feed the material in the reverse direction (rotate 180°) and sew again;

[0068] 3. Rotate or flip it 180° in the weft direction for the second time, feed the material and sew again. Advantages of reverse feeding: It avoids the defects of easy thread-off and thread-pulling in two sewings in the same direction;

[0069] 4. For the sewn board with one direction dense sewing and one direction normal sewing, there are approximately 2083 stitches per square meter, and the mechanical strength is relatively high. The tensile strength perpendicular to the board surface can reach more than 150 kPa;

[0070] Radial direction: Dense sewing, Weft direction: Normal sewing:

[0071] 1. After normal sewing, rotate or flip it 180° for the second time, offset the board by 30mm, and feed the material radially and sew. The tensile strength perpendicular to the board surface can reach more than 150 kPa;

[0072] Both radial and weft directions: Dense sewing:

[0073] 1. Operate according to normal sewing. The row spacing is generally fixed at 60mm - 65mm in a weft and warp grid pattern, and the stitch density is generally between 20mm - 38mm. It is mainly adjusted according to the thickness of different materials and the usage occasions. The denser the stitch density, the higher the tensile strength. Conversely, the looser the stitch density, the lower the tensile strength. For both radial and weft directions dense sewing, there are approximately 2777 stitches per square meter, and the running speed is not greater than 60 stitches per minute;

[0074] 2. Offset the normally processed composite insulation board 1 by 30mm in the weft direction, rotate or flip it 180°, feed the material and sew again, and then sew more densely in the weft direction;

[0075] 3. Offset the composite insulation board 1 that has been sewn densely in the weft direction by 30mm in the radial direction, rotate or flip it 180°, feed the material and sew again, and then sew more densely in the radial direction;

[0076] 4. Advantages of rotating or flipping 180° for weft feeding and sewing: It avoids the defects of easy thread breakage and thread pulling in two sewings in the same direction.

[0077] 5. The composite insulation board 1 sewn with both warp and weft directions encrypted has about 2,777 stitches per square meter, with high mechanical strength. The tensile strength perpendicular to the board surface can reach more than 200 kPa, and it is applied to special occasions with high strength requirements.

[0078] In this embodiment, there are three total setting methods for the waterproof and heat insulation composite layer: Class A waterproof and heat insulation composite layer, Class B waterproof and heat insulation composite layer, and Class C waterproof and heat insulation composite layer.

[0079] In this embodiment, referring to Figure 11 , the Class A waterproof and heat insulation composite layer includes one heat insulation layer 14 and one waterproof layer 15. The waterproof layer 15 is attached to one side of the heat insulation layer 14. After compounding, the thermal conductivity coefficient decreases significantly, and it has good waterproof and heat insulation effects after compounding.

[0080] In this embodiment, referring to Figure 10 , the Class B heat insulation and waterproof composite layer includes one heat insulation layer 14 and two waterproof layers 15. The two waterproof layers 15 are respectively attached to both sides of the heat insulation layer 14. After compounding, the thermal conductivity coefficient decreases significantly, and it can be used in occasions with relatively high waterproof requirements for current building prefabrication.

[0081] In this embodiment, referring to Figure 12 , the Class C heat insulation and waterproof composite layer includes one waterproof layer 15 and two heat insulation layers 14. The heat insulation layers 14 are respectively attached to both sides of the waterproof layer 15. After compounding, the thermal conductivity coefficient decreases significantly, and it can be used in occasions with extremely high waterproof requirements for current building prefabrication.

[0082] In this embodiment, the heat insulation layer 14 can adopt a fiber-based insulation board (thickness 50 mm - 150 mm, thermal conductivity coefficient ≤ 0.040 [W / (m·k)], bulk density 120 kg / m 3 ~160 kg / m 3 ), such as rock wool board. The waterproof layer 15 used in cooperation with it adopts a silica aerogel board (thickness 6 mm - 20 mm, thermal conductivity coefficient ≤ 0.023 [W / (m·k)], bulk density ≤ 215 kg / m 3 ).

[0083] The thermal conductivity coefficient of a single rock wool board is generally in the range of (0.038 - 0.040) W / (m·k). After being compounded with one layer of aerogel board and tested, the thermal conductivity coefficient drops to (0.030 - 0.032) W / (m·k). The water absorption of the rock wool board is relatively large, generally 1.0 kg / m 2 , while the water repellency rate of the aerogel board is more than 99%, and it hardly absorbs water. The surface water absorption after compounding is less than 0.4 kg / m2 ; After the two-layer aerogel plates are compounded and tested, the thermal conductivity drops to (0.026 - 0.028) W / (m·K), and the surface water absorption after compounding is less than 0.2 kg / m 2 ; When one layer of aerogel plate is compounded with two layers of rock wool plates, the thermal conductivity after compounding is generally in the range of (0.030 - 0.032) W / (m·K) after testing.

[0084] Furthermore, in this embodiment, the thermal insulation layer 14 can adopt a woven fiber-reinforced thermal insulation board, which is composed of a rock wool board (thickness 50 mm - 150 mm, thermal conductivity ≤ 0.040 [W / (m·K)], bulk density 120 kg / m 3 -160 kg / m 3 ), basalt fiber yarns (linear density 500 tex - 800 tex), and alkali-resistant fiberglass mesh cloth (unit area mass 120 g / m 2 -160 g / m 2 ).
